A spherical barrier is positioned close to the outlet orifice, so that as the compressed air exits it becomes a turbulent air flow. Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of The overfeed used for the core yarn(s) is always lower than that for the effect yarn(s); the former, normally between 5 - 15% whereas the latter can be up to 400%, again depending on the end-use. To assist the loop formation, the filaments are wetted prior to entering the jet, by either Spraying? In addition, the pin-twister may be replaced with a friction-twisting device [71]. The DTYs are considered to be highly stretchable yarns, because in addition to the recoverable part of the intrinsic extension from their melt spun structure, there is the added extension attributable to the Twist? Bicomponent Process: with this method the texture is obtained by twisting to together filaments of high and low potential shrinkage. There are small wool fibers with different lengths around the yarn. Draw Textured Yarn … The Texspun device is located in the heat stabilizing zone, so that as the yarn passes through the device the loops are torn and free fibre ends, very similar to staple fibre, are produced. The difference is that one yarn has been twisted into the opposite direction of the other yarn. By including a mechanical drawing stage(i.e. Similar as in the tangling of yarns the center of the ATY becomes randomly braided. Note that in the case of core effect type yarns, the two yarn paths must have their own drawing zone and therefore heating element. What is Fully Oriented Yarn (FOY)? High quality air jet textured yarns … There are small wool fibers with different lengths around the yarn. DTY: : Draw texturing yarn/ stretch textured yarn. A yarn comprising at least one textured core and one separately textured effect yarn, wherein the core yarn is covered periodically along the length with two or more helical wraps of the effect yarn to form a nubby thickening, the Nylon Drawn Textured Yarn 6 & 66 (Nylon DTY) Kayavlon Impex Pvt Ltd. is one of the foremost and leading Indenter, based at Surat, Gujarat, India. 9. During the earlier years of false-Twist? What is Fully Oriented Yarn (FOY)? lengths in the turbulent flow initially become separated, forming a profusion of loops of various sizes. The first type is called parallel yarns and the second type core effect yarns, and Fig.9 illustrates the production of both. ATY Air Textured Yarn, similar to cotton in appearance. 2. compaction resulting a false-Twist?

The color No is ZD7427 for polyester draw textured yarn and spandex covered yarn. In zone XB, the S-Twist? The Filament? and Twist? inserted; Twist? Such changes in the physical form of a fibre (several examples of which are shown in Figure 3) affect the behaviour and hand of fabrics made from them. The yarn is also constantly being twisted at the location X by some device, as its length moves through the distance AB. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? The yarns were parallel end textured on Eltex A T/HS air-jet texturing machine using the HemaJet with TIOO core under the following texturing conditions: Overfeed to jet Air … General polyester high elastic yarn or low elastic yarn are not available. Texturing Principle. Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of finished products on a machine. in the yarn length present in AX will increase to a constant value equal to Vd / Ns turns per metre. What's the difference between DTY and FDY ? Although both yarns are made from POY, ATY is a yarn with zillions of small loops, which give it a distinct feeling and look whereas DTY is a yarn with preferably no loops at all. will be present as it leaves. If in the main drawing stage, the draw ratio is cyclically varied from high to low, while the Twist? Single, or one-ply, yarns are single strands composed of fibres held together by at least a small amount of twist; or of filaments grouped together either with or without twist; or of narrow … Draw Texturised Yarn (DTY) is a fully drawn, fully oriented polyester multifilament yarn with soft crimp, high bulk and texture with cotton feel and very high durability and This is manufactured by texturising partially oriented yarn using texturising machines. This study is related to production and testing of air covered yarn from polyester and lycra on air covering machine. Effect of process variables on bulk DTY yarn can be in Semi Dull or Bright or Triloble Bright … McIntyre, J.E., and Daniels, P.N. air-jet textured. 3.       http://composite.about.com/library/glossary/c/bldef-c1269.htm  Jan 2012, 4. If required, an additional drawing zone placed between the air-jet and the heater can also be used to ensure smaller size loops are obtained. Filament?-yarn.html">http://www.textileglossary.com/terms/Filament?-yarn.html    Jan2012, 5.       http://www.miniknittingstuff.com/yarn2.htm  Jan2012. One or more ends of filament yarn are overfed at a constant rate to a special air jet, which blows, depending on the amount of overfeed between the inlet and outlet feeds, the yarns into a continuous string of smaller and larger loops. Core effect yarns are produced with two main components; core and the effect yarns. Types of yarn Classification based on number of strands Yarns can be described as single, or one-ply; ply, plied, or folded; or as cord, including cable and hawser types. Nylon yarns are in the range from  16.7 to 122.2 tex (15-110 den); Polypropylene yarns are typically 7.7 to 100tex (70 – 900den)     [ 73][74]. Although some of these features may be removed during downstream processing, sufficient are retained to give an enhanced textured appearance in the subsequent woven or knitted fabric. However, air-textured yarn (ATY) has millions of small loops that offer a distinct look and feel. Fig. Eltex AT/HS air-jet texturing machine and HemaJet with Tl 00core were used to produce air textured yarns with the texturing parameters of33.3% E-mail:HL-12@zjhuilong.cn ... dope dyed polyester yarn is use natural or synthetic polymer as raw material, through the process of chemical or physical methods. Keywords- False twist texturing, Draw … Highly stretchable yarns can be made by applying high levels of false-Twist?, resulting in Twist? After spinning and drawing, a slight intermingling is given to the flat yarn to facilitate the easy post spinning processes[2]. With the clockwise spiral, the inclination of the helix mirrors the inclination in the letter Z, and the Twist? A third pair of rollers would then be used as the output rollers. Textiles Terms & Definitions, Compiled by The Textile Institute Textile Terms and Definitions Committee, Ed. 4346552 Bulky textured multifilament yarn 1982-08-31 Negishi et al. Air texturing of a yarn is one of the most versatile methods of yarn texturing as it can combine type of filament Yarn together. device. The rotation of the pin is effected by a driven disc assembly. extension, but retain a high bulk, an additional heating stage is incorporated after the roller-pair B. or dipping the yarn into a water bath; the water aids separation of the filaments and acts as a Lubricant? Difference between maximum and minimum values of elongation of fabrics with S7 and S11 yarn in weft is 37 % R– = 0.104638 %, when difference between maximum and minimum The technical specifications of draw textured yarn have made it ideal for a wide range of applications as it can be moulded in several ways as well. in the clockwise direction, the yarn length present within the zone AX, inserting Z-Twist?. Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to . Other articles where Textured yarn is discussed: man-made fibre: Texturing: Texturing is the formation of crimp, loops, coils, or crinkles in filaments. There is also pronounced effect of draw ratio and D/Y ratio shown on the textured yarn structure and properties. Page 2 of 17 give greater bulk, higher stretch and more pleasing aesthetics. Usually 18% to 30% overfeed may be applied, depending on end-use requirements; parallel yarns are commonly used cut pile plush fabrics. Get info of suppliers, manufacturers, exporters, traders of Textured Yarn for buying in India. {dpf}, the most popular yarns being more towards 1dpf or finer. Therefore a variety of air-texturing jets are available to cover the different ranges of dpf. FDY yarn is available at Kayavlon in 3 lustre - Semi-dull (SD), Bright (BR) and Trilobal Bright (TBR). DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat covers, bags and numerous different things. Professional manufacturer of dope dyed polyester filament yarn in china,produce polyester yarn,polyester DTY yarn,polyester fdy yarn,with high-quality and competitive price. The Textile Institute, 1993. This type of application field is common to both flat and textured yarn. The heating element is essential for polyester POY, but nylon and polypropylene POY may be cold drawn. There is no universal nozzle capable of processing any supply yarn … These latter devices enable higher twisting speeds, 20 x106 rpm as opposed to 8 x105 for pin twisting, resulting in production rates of up to 12000m/min, depending on polymer and yarn count. The heated yarn is passed between a pair of geared wheels or some similar device (gear crimping). This is an assembly of overlapping discs which enables the CF yarn to be directly friction twisted, replacing the need for the hollow spindle. Usually jets operate at pressures of about 10 bar (140 psi) and the actual texturing occurs directly at the exit of the jet in what is a turbulent supersonic air stream. On the contrary, it is low elastic yarn. The yarn is simultaneously twisted and drawn. When the process is started the twisted yarn on the right side is discarded to waste. High elastic elongation is high elastic yarns. will remain in the yarn, since the Z-Twist? Although CF yarns of virtually any polymer can be air-jet textured, the number of filaments and the dtex/denier per Filament? Various techniques have been developed, therefore, to modify their appearance. For example cellulosic rayon which is not a thermoplastic, can be air-jet textured and air-jet textured E-glass is widely used for technical applications. When POY is fed into the machine, the yarn has to be drawn. After the false twisting, the DTY passes through the additional heating zone to become a set-DTY. This heating stage gives an additional heat-setting treatment which reduces the intrinsic Elasticity? One Heater DTY is normally woolly & more stretchable as compared to DTY with two Heaters. Tel: 01484 346500 | Email: enquiries@textilehouse.co.uk, Texturing processes are essentially concerned with introducing bulkiness into continuous-, http://composite.about.com/library/glossary/c/bldef-c1269.htm, http://www.miniknittingstuff.com/yarn2.htm, http://www.allproducts.com/textile/acelon/12-split_micro_filament.html, http://www.polyspintex.com/ups/text06.htm, False twist textured yarns: Principles, processing and applications, Textured Yarn Technology: Production, properties, and processing. By including a mechanical drawing stage(i.e. loss increases with both factors. One of the most important advantages of textured yarn is that it gives good comfort as the result of the air entrapped between the interstices of the yarn… extensions of 150 to 300%. as well as their forms (FDY/FOY, POY) can be processed to a large range of yarns for a wide variety of applications such as: … In the continuous production of filaments, after spinning the filaments … Figure 3: Application of Intermingling While Spinning. and Spun Yarns”, Woven Cloth Construction, pub. The temperatures must be hot enough to ensure that the yarns are adequately treated. [1] There may be a slight loss of Twist? Smaller loops are more stable and give a better bulkiness than larger loops. If the twisting device is rotating at Ns rpm in the direction shown, then when viewed from A, along the length AX, it will appear to be turning clockwise. |. All types of continuous filament yarns (PES, PA, PP, Glass, etc.) Instability of air-jet tex­ tured yarns also first decreases and then increases with the increasing shrinkage difference. The major apparel applications for draw-twist are in knitted garments, especially double jersey for women’s outerwear and woven fabrics. Two fully drawn multifilament polyester yarns of 70 denier (7.77 tex)l36 filaments and 70 denier (7.77 te x)172 filaments were used as parent material for producing two different textured yarns. Air jet textured yarns are a spun look like alternative to the more synthetic hand of false twist textured yarns. Both, S and Z means real twist in a yarn. and the term false Twist?, and how the latter is produced. 9 Processes for Parallel and Core Effect ATY. Because the yarns are with-drawn slowly, they buckle and back up on themselves. texturing the reader is referred to [70], Fig.4 Illustration of the False Twisting Action, Fig.5 Illustration of False-Twist? is called Z-Twist?. texturing process it is necessary to first consider the meaning of real Twist? The individual filaments are compacted by the air … In … Figure 3 shows that loop density of steam-jet textured yarns increases and air-jet textured yarn decreases when effect-yarn draw ratio is increased. Has nothing to do with the production process, but now widely circulated, will it as a symbol of spin-draw … Yarns based on Poly(trimethylene trerephthalete)”, Chemical Fibres International, 47, 72-74, 1997. DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat … The study suggests that shrink­ age difference in the feeder yarn is not an effective way to increase the bulk of air-jet textured yams. An example of the set-DTY process is illustrated by Fig.7. The two most popular textured yarn structures are draw-twist texturing and air-jet texturing. Although false-Twist? textured PET filament yarns (PET DTY yarn) with five different filament fineness (3.05 dtex, 1.15 dtex, 0.76 dtex, 0.57 dtex and 0.33 dtex) were used as cores to manufacture cotton covered filament yarns on a modified ring Table I. In a similar way, filaments could be caught by the warp yarn while an uncompact textured weft yarn is travelling through the narrow warp shed and create irregularities on a woven fabric[3]. draw texturing is the most widely used method for converting flat thermoplastic CF yarns to ones of more bulky structures, air-jet texturing has become increasingly important because of  it capability to process CF yarns of any polymer type, not just thermoplastics, and also glass filaments. The figure shows the melt-spinning of nylon POY, which is then transferred to the draw texturing process. 3. These entangle as the filaments get pulled together by removal rollers, to deliver an air- textured CF yarn. Simultaneously, the yarn length present within the zone XB will receive a counter clockwise torque, inserting S-Twist?. Generally, vortex type jets are used for products which require less than 100%  overfeed, whereas the venturi type of jet can be used with overfeeds of up to several hundred per cent. Loop frequency, loop dimensions, loop stability and physical bulk are the important characteristics of air textured yarns. An example of this method is the taslam process; Air jet textured yarn. being preferred. 7. The difference between colored spinning and dyed yarn Is the dyed yarn colored spinning? Since false-Twist? A ratio > 1, of input to output speed is termed the overfeed. Subjecting the resulting yarn to washing or steaming results in the differential shrinkage of the filaments to form the ulked profile. 'Textured Yarn' definition with manufacturers. The DP5-T DIGICONE® fastflex™ air texturing machine is designed for the flexible production of high quality air jet textured yarns. Wraps per inch for each yarn weight is the number of times you can wrap the yarn around one inch of a ruler. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? The air covering process consists of covering an elastomeric yarn with other continuous textured yarns.This process takes place through an air flow controlled by a special jet which opens the fibre of the covering yarn and closes it A further addition to the process line can be made, used to convert the small loops into hairs, thereby simulating the structure of staple spun yarns which have short protrusions of fibre ends from the yarn’s surface. Air consumption is one significant cost factor in the process which must be kept as low as possible. 10. Should the yarn break, the twisted yarn on the left hand side also goes to waste. Currently, the practice is to use between 1.1 and 2.2 detex (1 and 2 denier) per Filament? What is the difference between S and Z twist: There is a little and a lot of difference. It was built in 1969 as a result of vision of its founder Sh. Yarns should be textured with minimum overfeed to also minimize plucking. Spinning speeds between 3000 m/min to 4000m/min provides a partially oriented yarn which later requires draw of two during the draw texturizing. The speed of shaft 2 is always higher by the factor of the necessary draw ratio for the particular yarn and process. Loops are formed in individual filaments by over-feeding into a turbulent airstream (air-textured… Dyed yarn: It is formed by dyeing the yarn through a dyeing process, which is first spinning and then dyeing. The difference is that one yarn has been twisted into the opposite direction of the other yarn. %100 polyester draw texturizing yarn used are upholstery fabric , textile ,narrow weaving ,circular knitting ,lyrca clothes and traditional rugs industry due to its softness ,brightness and strenght . contraction  at low applied force) depending on the level of false twisting. DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. POY is mainly used in texturizing to make textured yarn and can also be used in draw warping for weaving and warp knitting of fabrics. 4. Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted & drawn. Brown, N.S; and Chuah,H.H, “Texturing of Textile Filament? We will show you the difference between a parallel and a Hand, or … extension of the DTY, and the yarn is said to be stabilised or a set-DTY. DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat covers, bags and numerous different things. From here the yarn is fed to Shaft 2. E … Draw textured yarn (DTY) is made from Partially Oriented Yarn(POY). finishes and a yarn of 68trilobal filaments (2.44 dtex per filament) were textured. 6 Abhay Trading Company has emerged as one of Leading Yarn Suppliers for manufacturers and dealers in Hosiery Industries. The major application for BCF yarns is tufted carpets, but the  technology has been developed to run at higher speeds and produce  finer counts which enables BCF yarns to enter the textile and apparel sectors such as furnishings and outerwear. Kayavlon is exporting FDY yarns from India, China,Malaysia, Thailand March 1999 ; Indian Journal of Fibre and Textile Research 24(1):16-20; Authors: V. K. Kothari. Keywords: Air-jet texturing, Filament feed'yam, Shrinkage potential, Textured yarn … When Twist? Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to Page 2 of 17 give … Vijay Kumar Yadav. Fig.3. Interlacing of filaments in the jet can cause the loops to be locked into the yarn so that any further twisting is unnecessary. POY are preferred for air jet textured yarns largely because they are less expensive than FOY. imparted by the texturing process. General polyester high elastic yarn or low elastic yarn are not available. Therefore, if a yarn end is held outside the tube and cut, it would go inside the tube on passing compressed air. Air-jet texturing of draw-textured yarns. Investigation of the influence of effect-yarn draw and effect-yarn overfeed on texturing performance: comparison between air-jet and steam-jet textured yarn Ganemulle Lekamalage Dharmasri Wickramasinghe1* and Peter William Foster2 *Correspondence:dharmasri@uom.lk 1Department of Textile and Clothing … Various air-jet designs may be used to make ATY and DATY; Fig.8 illustrates one of the widely used jets, referred to as an axial-jet (venturi jet). Polyester yarns are normally within the count range of 55.6 to 333tex (50 to 300 den), with the emphasis on 83.3 tex to 166.7 tex (75 to 150 den). ester (DTY) Drawn Textured Yarn (DTY)Polyester DTY is obtained when Polyester POY is simultaneously twisted and drawn. Free listing for companies. If you would count the twist in both … Textile - Textile - Types of yarn: Yarns can be described as single, or one-ply; ply, plied, or folded; or as cord, including cable and hawser types. As Fig 6 illustrates, the pin twister is a hollow spindle with a central pin positioned across the tubular interior. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? It doesn't matter what size or width your ruler is as this metric measures the thickness of the yarn rather than the length. If a twisting device, through which the yarn passes, is located so that the Z-twisting action (the clockwise torque) occurs on the yarn as the yarn is made to run into the device, and as the yarn runs out of the device the S-twisting action (the counter clockwise torque) occurs, then no Twist? Yarn preparation includes the addition of 3 - 4% wax emulsion after texturing to minimize plucking on beams. The yarn is knitted into a fabric, heat-set and unravelled (knit-deknit). “Acelon Chemicals & Fibre Corporation”, http://www.allproducts.com/textile/acelon/12-split_micro_filament.html. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? Despite the fact that false-Twist? Air-jet texturing can be used to process FDY/FOY (to give an air- textured yarn – ATY) or with a pre-drawing stage in an integrated draw-texturing system to convert POY to a drawn-air textured yarn – DATY). texturing and air-jet texturing, the former being the dominant. (BCF) Technology. texturing requires the filaments to be initially heated above their Tg, the process is only suitable for thermoplastic polymeric  filaments. The twisting is done with a friction device, such as a set of rotating … Where is the difference between ATY Yarn and DTY Yarn ? is referred to as S-Twist? There are basically 2 types of yarns which can be produced with air texturing. 57/209 4035879 Apparatus for producing texturized yarns 1977-07-19 Schippers 28/246 4034548 Process for the production of stretch-textured yarns Both may be comprised of one or more POY. The operating stages of the DATY machine (Fig.9) would therefore be of a similar configuration to the DTY machine, but with the false-twisting device replaced by the air-jet system. Textured Filament? This means that within a short time of starting the twisting process, Z-Twist? insertion is similarly varied, the textured yarn will have thick and thin places along its length. Draw textured yarn (DTY) and air-textured yarn are both made from partially oriented yarn (POY). 6. Air textured yarn is very bulky with permanent crimps and loops. The elasticity can be obviously felt when pulling the two ends of the high elastic yarn. The stuffer-box method is a fast and inexpensive method for carpeting yarn. What are the benefits of textured yarns? DTY yarn can be in Semi Dull or Bright or Triloble … Importantly, after the action of twisting the inserted Twist? DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. Both, S and Z means real twist in a yarn. In a very short time, the Z-Twist? The fabric woven with it has a cotton feeling. FOY Polyester (also called Fully Drawn Yarn - FDY), is produced by a process similar to POY manufacturing except that the yarn is produced at even higher spinning speeds coupled with intermediate drawing … One or more ends of filament yarn are overfed at a constant rate to a special air jet, which blows, depending on the amount of overfeed between the inlet and outlet feeds, the yarns into a continuous string of smaller and larger loops. Rarely are yarns with a higher than 3.3dtex (3 denier) per Filament? present in the yarn length passing through the zone will increase to a maximum value and then decrease to zero. [1] A fibre being a textile raw material, generally characterised by flexibility, fineness and a high ratio of length to thickness(diameter):- aspect ratio. In this study yarns are produced with different level of air pressure i.e. PET requires a long time for heat transfer to the core of the filaments and further development work is needed, for PET-BCF yarns to become available. Instability of air-jet textured yarns also first decreases and then increases with the increasing shrinkage difference. POY is mainly used in texturizing to make textured yarn and can also be used in draw warping for weaving and warp knitting of fabrics. [13] Chuah, H. H. (2004). The heated yarn is passed over a knife edge (edge crimping). Yarns”, Journal of Rheology, 16, 3, 557-577, 1972. as the fibres will try to recover from the strain of being twisted. a hot-draw zone)  before the heating/twisting/cooling zone, POY yarns could then be utilised, giving better process economics and product variety in terms of bulk and stretch, depending on the pre-drawing; the yarn being referred to as a draw-textured yarn or DTY. Of input to output speed is termed the overfeed turbulent flow to difference between air textured yarn and draw textured yarn.

Physical properties of drawn yarns and textured yarns were reduced w ith increasing of OPP fraction. yarns find applications in a wide range of technical end uses. A spherical barrier is positioned close to the outlet orifice, so that as the compressed air exits it becomes a turbulent air flow. Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of The overfeed used for the core yarn(s) is always lower than that for the effect yarn(s); the former, normally between 5 - 15% whereas the latter can be up to 400%, again depending on the end-use. To assist the loop formation, the filaments are wetted prior to entering the jet, by either Spraying? In addition, the pin-twister may be replaced with a friction-twisting device [71]. The DTYs are considered to be highly stretchable yarns, because in addition to the recoverable part of the intrinsic extension from their melt spun structure, there is the added extension attributable to the Twist? Bicomponent Process: with this method the texture is obtained by twisting to together filaments of high and low potential shrinkage. There are small wool fibers with different lengths around the yarn. Draw Textured Yarn … The Texspun device is located in the heat stabilizing zone, so that as the yarn passes through the device the loops are torn and free fibre ends, very similar to staple fibre, are produced. The difference is that one yarn has been twisted into the opposite direction of the other yarn. By including a mechanical drawing stage(i.e. Similar as in the tangling of yarns the center of the ATY becomes randomly braided. Note that in the case of core effect type yarns, the two yarn paths must have their own drawing zone and therefore heating element. What is Fully Oriented Yarn (FOY)? High quality air jet textured yarns … There are small wool fibers with different lengths around the yarn. DTY: : Draw texturing yarn/ stretch textured yarn. A yarn comprising at least one textured core and one separately textured effect yarn, wherein the core yarn is covered periodically along the length with two or more helical wraps of the effect yarn to form a nubby thickening, the Nylon Drawn Textured Yarn 6 & 66 (Nylon DTY) Kayavlon Impex Pvt Ltd. is one of the foremost and leading Indenter, based at Surat, Gujarat, India. 9. During the earlier years of false-Twist? What is Fully Oriented Yarn (FOY)? lengths in the turbulent flow initially become separated, forming a profusion of loops of various sizes. The first type is called parallel yarns and the second type core effect yarns, and Fig.9 illustrates the production of both. ATY Air Textured Yarn, similar to cotton in appearance. 2. compaction resulting a false-Twist?

The color No is ZD7427 for polyester draw textured yarn and spandex covered yarn. In zone XB, the S-Twist? The Filament? and Twist? inserted; Twist? Such changes in the physical form of a fibre (several examples of which are shown in Figure 3) affect the behaviour and hand of fabrics made from them. The yarn is also constantly being twisted at the location X by some device, as its length moves through the distance AB. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? The yarns were parallel end textured on Eltex A T/HS air-jet texturing machine using the HemaJet with TIOO core under the following texturing conditions: Overfeed to jet Air … General polyester high elastic yarn or low elastic yarn are not available. Texturing Principle. Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of finished products on a machine. in the yarn length present in AX will increase to a constant value equal to Vd / Ns turns per metre. What's the difference between DTY and FDY ? Although both yarns are made from POY, ATY is a yarn with zillions of small loops, which give it a distinct feeling and look whereas DTY is a yarn with preferably no loops at all. will be present as it leaves. If in the main drawing stage, the draw ratio is cyclically varied from high to low, while the Twist? Single, or one-ply, yarns are single strands composed of fibres held together by at least a small amount of twist; or of filaments grouped together either with or without twist; or of narrow … Draw Texturised Yarn (DTY) is a fully drawn, fully oriented polyester multifilament yarn with soft crimp, high bulk and texture with cotton feel and very high durability and This is manufactured by texturising partially oriented yarn using texturising machines. This study is related to production and testing of air covered yarn from polyester and lycra on air covering machine. Effect of process variables on bulk DTY yarn can be in Semi Dull or Bright or Triloble Bright … McIntyre, J.E., and Daniels, P.N. air-jet textured. 3.       http://composite.about.com/library/glossary/c/bldef-c1269.htm  Jan 2012, 4. If required, an additional drawing zone placed between the air-jet and the heater can also be used to ensure smaller size loops are obtained. Filament?-yarn.html">http://www.textileglossary.com/terms/Filament?-yarn.html    Jan2012, 5.       http://www.miniknittingstuff.com/yarn2.htm  Jan2012. One or more ends of filament yarn are overfed at a constant rate to a special air jet, which blows, depending on the amount of overfeed between the inlet and outlet feeds, the yarns into a continuous string of smaller and larger loops. Core effect yarns are produced with two main components; core and the effect yarns. Types of yarn Classification based on number of strands Yarns can be described as single, or one-ply; ply, plied, or folded; or as cord, including cable and hawser types. Nylon yarns are in the range from  16.7 to 122.2 tex (15-110 den); Polypropylene yarns are typically 7.7 to 100tex (70 – 900den)     [ 73][74]. Although some of these features may be removed during downstream processing, sufficient are retained to give an enhanced textured appearance in the subsequent woven or knitted fabric. However, air-textured yarn (ATY) has millions of small loops that offer a distinct look and feel. Fig. Eltex AT/HS air-jet texturing machine and HemaJet with Tl 00core were used to produce air textured yarns with the texturing parameters of33.3% E-mail:HL-12@zjhuilong.cn ... dope dyed polyester yarn is use natural or synthetic polymer as raw material, through the process of chemical or physical methods. Keywords- False twist texturing, Draw … Highly stretchable yarns can be made by applying high levels of false-Twist?, resulting in Twist? After spinning and drawing, a slight intermingling is given to the flat yarn to facilitate the easy post spinning processes[2]. With the clockwise spiral, the inclination of the helix mirrors the inclination in the letter Z, and the Twist? A third pair of rollers would then be used as the output rollers. Textiles Terms & Definitions, Compiled by The Textile Institute Textile Terms and Definitions Committee, Ed. 4346552 Bulky textured multifilament yarn 1982-08-31 Negishi et al. Air texturing of a yarn is one of the most versatile methods of yarn texturing as it can combine type of filament Yarn together. device. The rotation of the pin is effected by a driven disc assembly. extension, but retain a high bulk, an additional heating stage is incorporated after the roller-pair B. or dipping the yarn into a water bath; the water aids separation of the filaments and acts as a Lubricant? Difference between maximum and minimum values of elongation of fabrics with S7 and S11 yarn in weft is 37 % R– = 0.104638 %, when difference between maximum and minimum The technical specifications of draw textured yarn have made it ideal for a wide range of applications as it can be moulded in several ways as well. in the clockwise direction, the yarn length present within the zone AX, inserting Z-Twist?. Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to . Other articles where Textured yarn is discussed: man-made fibre: Texturing: Texturing is the formation of crimp, loops, coils, or crinkles in filaments. There is also pronounced effect of draw ratio and D/Y ratio shown on the textured yarn structure and properties. Page 2 of 17 give greater bulk, higher stretch and more pleasing aesthetics. Usually 18% to 30% overfeed may be applied, depending on end-use requirements; parallel yarns are commonly used cut pile plush fabrics. Get info of suppliers, manufacturers, exporters, traders of Textured Yarn for buying in India. {dpf}, the most popular yarns being more towards 1dpf or finer. Therefore a variety of air-texturing jets are available to cover the different ranges of dpf. FDY yarn is available at Kayavlon in 3 lustre - Semi-dull (SD), Bright (BR) and Trilobal Bright (TBR). DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat covers, bags and numerous different things. Professional manufacturer of dope dyed polyester filament yarn in china,produce polyester yarn,polyester DTY yarn,polyester fdy yarn,with high-quality and competitive price. The Textile Institute, 1993. This type of application field is common to both flat and textured yarn. The heating element is essential for polyester POY, but nylon and polypropylene POY may be cold drawn. There is no universal nozzle capable of processing any supply yarn … These latter devices enable higher twisting speeds, 20 x106 rpm as opposed to 8 x105 for pin twisting, resulting in production rates of up to 12000m/min, depending on polymer and yarn count. The heated yarn is passed between a pair of geared wheels or some similar device (gear crimping). This is an assembly of overlapping discs which enables the CF yarn to be directly friction twisted, replacing the need for the hollow spindle. Usually jets operate at pressures of about 10 bar (140 psi) and the actual texturing occurs directly at the exit of the jet in what is a turbulent supersonic air stream. On the contrary, it is low elastic yarn. The yarn is simultaneously twisted and drawn. When the process is started the twisted yarn on the right side is discarded to waste. High elastic elongation is high elastic yarns. will remain in the yarn, since the Z-Twist? Although CF yarns of virtually any polymer can be air-jet textured, the number of filaments and the dtex/denier per Filament? Various techniques have been developed, therefore, to modify their appearance. For example cellulosic rayon which is not a thermoplastic, can be air-jet textured and air-jet textured E-glass is widely used for technical applications. When POY is fed into the machine, the yarn has to be drawn. After the false twisting, the DTY passes through the additional heating zone to become a set-DTY. This heating stage gives an additional heat-setting treatment which reduces the intrinsic Elasticity? One Heater DTY is normally woolly & more stretchable as compared to DTY with two Heaters. Tel: 01484 346500 | Email: enquiries@textilehouse.co.uk, Texturing processes are essentially concerned with introducing bulkiness into continuous-, http://composite.about.com/library/glossary/c/bldef-c1269.htm, http://www.miniknittingstuff.com/yarn2.htm, http://www.allproducts.com/textile/acelon/12-split_micro_filament.html, http://www.polyspintex.com/ups/text06.htm, False twist textured yarns: Principles, processing and applications, Textured Yarn Technology: Production, properties, and processing. By including a mechanical drawing stage(i.e. loss increases with both factors. One of the most important advantages of textured yarn is that it gives good comfort as the result of the air entrapped between the interstices of the yarn… extensions of 150 to 300%. as well as their forms (FDY/FOY, POY) can be processed to a large range of yarns for a wide variety of applications such as: … In the continuous production of filaments, after spinning the filaments … Figure 3: Application of Intermingling While Spinning. and Spun Yarns”, Woven Cloth Construction, pub. The temperatures must be hot enough to ensure that the yarns are adequately treated. [1] There may be a slight loss of Twist? Smaller loops are more stable and give a better bulkiness than larger loops. If the twisting device is rotating at Ns rpm in the direction shown, then when viewed from A, along the length AX, it will appear to be turning clockwise. |. All types of continuous filament yarns (PES, PA, PP, Glass, etc.) Instability of air-jet tex­ tured yarns also first decreases and then increases with the increasing shrinkage difference. The major apparel applications for draw-twist are in knitted garments, especially double jersey for women’s outerwear and woven fabrics. Two fully drawn multifilament polyester yarns of 70 denier (7.77 tex)l36 filaments and 70 denier (7.77 te x)172 filaments were used as parent material for producing two different textured yarns. Air jet textured yarns are a spun look like alternative to the more synthetic hand of false twist textured yarns. Both, S and Z means real twist in a yarn. and the term false Twist?, and how the latter is produced. 9 Processes for Parallel and Core Effect ATY. Because the yarns are with-drawn slowly, they buckle and back up on themselves. texturing the reader is referred to [70], Fig.4 Illustration of the False Twisting Action, Fig.5 Illustration of False-Twist? is called Z-Twist?. texturing process it is necessary to first consider the meaning of real Twist? The individual filaments are compacted by the air … In … Figure 3 shows that loop density of steam-jet textured yarns increases and air-jet textured yarn decreases when effect-yarn draw ratio is increased. Has nothing to do with the production process, but now widely circulated, will it as a symbol of spin-draw … Yarns based on Poly(trimethylene trerephthalete)”, Chemical Fibres International, 47, 72-74, 1997. DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat … The study suggests that shrink­ age difference in the feeder yarn is not an effective way to increase the bulk of air-jet textured yams. An example of the set-DTY process is illustrated by Fig.7. The two most popular textured yarn structures are draw-twist texturing and air-jet texturing. Although false-Twist? textured PET filament yarns (PET DTY yarn) with five different filament fineness (3.05 dtex, 1.15 dtex, 0.76 dtex, 0.57 dtex and 0.33 dtex) were used as cores to manufacture cotton covered filament yarns on a modified ring Table I. In a similar way, filaments could be caught by the warp yarn while an uncompact textured weft yarn is travelling through the narrow warp shed and create irregularities on a woven fabric[3]. draw texturing is the most widely used method for converting flat thermoplastic CF yarns to ones of more bulky structures, air-jet texturing has become increasingly important because of  it capability to process CF yarns of any polymer type, not just thermoplastics, and also glass filaments. The figure shows the melt-spinning of nylon POY, which is then transferred to the draw texturing process. 3. These entangle as the filaments get pulled together by removal rollers, to deliver an air- textured CF yarn. Simultaneously, the yarn length present within the zone XB will receive a counter clockwise torque, inserting S-Twist?. Generally, vortex type jets are used for products which require less than 100%  overfeed, whereas the venturi type of jet can be used with overfeeds of up to several hundred per cent. Loop frequency, loop dimensions, loop stability and physical bulk are the important characteristics of air textured yarns. An example of this method is the taslam process; Air jet textured yarn. being preferred. 7. The difference between colored spinning and dyed yarn Is the dyed yarn colored spinning? Since false-Twist? A ratio > 1, of input to output speed is termed the overfeed. Subjecting the resulting yarn to washing or steaming results in the differential shrinkage of the filaments to form the ulked profile. 'Textured Yarn' definition with manufacturers. The DP5-T DIGICONE® fastflex™ air texturing machine is designed for the flexible production of high quality air jet textured yarns. Wraps per inch for each yarn weight is the number of times you can wrap the yarn around one inch of a ruler. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? The air covering process consists of covering an elastomeric yarn with other continuous textured yarns.This process takes place through an air flow controlled by a special jet which opens the fibre of the covering yarn and closes it A further addition to the process line can be made, used to convert the small loops into hairs, thereby simulating the structure of staple spun yarns which have short protrusions of fibre ends from the yarn’s surface. Air consumption is one significant cost factor in the process which must be kept as low as possible. 10. Should the yarn break, the twisted yarn on the left hand side also goes to waste. Currently, the practice is to use between 1.1 and 2.2 detex (1 and 2 denier) per Filament? What is the difference between S and Z twist: There is a little and a lot of difference. It was built in 1969 as a result of vision of its founder Sh. Yarns should be textured with minimum overfeed to also minimize plucking. Spinning speeds between 3000 m/min to 4000m/min provides a partially oriented yarn which later requires draw of two during the draw texturizing. The speed of shaft 2 is always higher by the factor of the necessary draw ratio for the particular yarn and process. Loops are formed in individual filaments by over-feeding into a turbulent airstream (air-textured… Dyed yarn: It is formed by dyeing the yarn through a dyeing process, which is first spinning and then dyeing. The difference is that one yarn has been twisted into the opposite direction of the other yarn. %100 polyester draw texturizing yarn used are upholstery fabric , textile ,narrow weaving ,circular knitting ,lyrca clothes and traditional rugs industry due to its softness ,brightness and strenght . contraction  at low applied force) depending on the level of false twisting. DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. POY is mainly used in texturizing to make textured yarn and can also be used in draw warping for weaving and warp knitting of fabrics. 4. Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted & drawn. Brown, N.S; and Chuah,H.H, “Texturing of Textile Filament? We will show you the difference between a parallel and a Hand, or … extension of the DTY, and the yarn is said to be stabilised or a set-DTY. DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat covers, bags and numerous different things. From here the yarn is fed to Shaft 2. E … Draw textured yarn (DTY) is made from Partially Oriented Yarn(POY). finishes and a yarn of 68trilobal filaments (2.44 dtex per filament) were textured. 6 Abhay Trading Company has emerged as one of Leading Yarn Suppliers for manufacturers and dealers in Hosiery Industries. The major application for BCF yarns is tufted carpets, but the  technology has been developed to run at higher speeds and produce  finer counts which enables BCF yarns to enter the textile and apparel sectors such as furnishings and outerwear. Kayavlon is exporting FDY yarns from India, China,Malaysia, Thailand March 1999 ; Indian Journal of Fibre and Textile Research 24(1):16-20; Authors: V. K. Kothari. Keywords: Air-jet texturing, Filament feed'yam, Shrinkage potential, Textured yarn … When Twist? Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to Page 2 of 17 give … Vijay Kumar Yadav. Fig.3. Interlacing of filaments in the jet can cause the loops to be locked into the yarn so that any further twisting is unnecessary. POY are preferred for air jet textured yarns largely because they are less expensive than FOY. imparted by the texturing process. General polyester high elastic yarn or low elastic yarn are not available. Therefore, if a yarn end is held outside the tube and cut, it would go inside the tube on passing compressed air. Air-jet texturing of draw-textured yarns. Investigation of the influence of effect-yarn draw and effect-yarn overfeed on texturing performance: comparison between air-jet and steam-jet textured yarn Ganemulle Lekamalage Dharmasri Wickramasinghe1* and Peter William Foster2 *Correspondence:dharmasri@uom.lk 1Department of Textile and Clothing … Various air-jet designs may be used to make ATY and DATY; Fig.8 illustrates one of the widely used jets, referred to as an axial-jet (venturi jet). Polyester yarns are normally within the count range of 55.6 to 333tex (50 to 300 den), with the emphasis on 83.3 tex to 166.7 tex (75 to 150 den). ester (DTY) Drawn Textured Yarn (DTY)Polyester DTY is obtained when Polyester POY is simultaneously twisted and drawn. Free listing for companies. If you would count the twist in both … Textile - Textile - Types of yarn: Yarns can be described as single, or one-ply; ply, plied, or folded; or as cord, including cable and hawser types. As Fig 6 illustrates, the pin twister is a hollow spindle with a central pin positioned across the tubular interior. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? It doesn't matter what size or width your ruler is as this metric measures the thickness of the yarn rather than the length. If a twisting device, through which the yarn passes, is located so that the Z-twisting action (the clockwise torque) occurs on the yarn as the yarn is made to run into the device, and as the yarn runs out of the device the S-twisting action (the counter clockwise torque) occurs, then no Twist? Yarn preparation includes the addition of 3 - 4% wax emulsion after texturing to minimize plucking on beams. The yarn is knitted into a fabric, heat-set and unravelled (knit-deknit). “Acelon Chemicals & Fibre Corporation”, http://www.allproducts.com/textile/acelon/12-split_micro_filament.html. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? Despite the fact that false-Twist? Air-jet texturing can be used to process FDY/FOY (to give an air- textured yarn – ATY) or with a pre-drawing stage in an integrated draw-texturing system to convert POY to a drawn-air textured yarn – DATY). texturing and air-jet texturing, the former being the dominant. (BCF) Technology. texturing requires the filaments to be initially heated above their Tg, the process is only suitable for thermoplastic polymeric  filaments. The twisting is done with a friction device, such as a set of rotating … Where is the difference between ATY Yarn and DTY Yarn ? is referred to as S-Twist? There are basically 2 types of yarns which can be produced with air texturing. 57/209 4035879 Apparatus for producing texturized yarns 1977-07-19 Schippers 28/246 4034548 Process for the production of stretch-textured yarns Both may be comprised of one or more POY. The operating stages of the DATY machine (Fig.9) would therefore be of a similar configuration to the DTY machine, but with the false-twisting device replaced by the air-jet system. Textured Filament? This means that within a short time of starting the twisting process, Z-Twist? insertion is similarly varied, the textured yarn will have thick and thin places along its length. Draw textured yarn (DTY) and air-textured yarn are both made from partially oriented yarn (POY). 6. Air textured yarn is very bulky with permanent crimps and loops. The elasticity can be obviously felt when pulling the two ends of the high elastic yarn. The stuffer-box method is a fast and inexpensive method for carpeting yarn. What are the benefits of textured yarns? DTY yarn can be in Semi Dull or Bright or Triloble … Importantly, after the action of twisting the inserted Twist? DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. Both, S and Z means real twist in a yarn. In a very short time, the Z-Twist? The fabric woven with it has a cotton feeling. FOY Polyester (also called Fully Drawn Yarn - FDY), is produced by a process similar to POY manufacturing except that the yarn is produced at even higher spinning speeds coupled with intermediate drawing … One or more ends of filament yarn are overfed at a constant rate to a special air jet, which blows, depending on the amount of overfeed between the inlet and outlet feeds, the yarns into a continuous string of smaller and larger loops. Rarely are yarns with a higher than 3.3dtex (3 denier) per Filament? present in the yarn length passing through the zone will increase to a maximum value and then decrease to zero. [1] A fibre being a textile raw material, generally characterised by flexibility, fineness and a high ratio of length to thickness(diameter):- aspect ratio. In this study yarns are produced with different level of air pressure i.e. PET requires a long time for heat transfer to the core of the filaments and further development work is needed, for PET-BCF yarns to become available. Instability of air-jet textured yarns also first decreases and then increases with the increasing shrinkage difference. POY is mainly used in texturizing to make textured yarn and can also be used in draw warping for weaving and warp knitting of fabrics. [13] Chuah, H. H. (2004). The heated yarn is passed over a knife edge (edge crimping). Yarns”, Journal of Rheology, 16, 3, 557-577, 1972. as the fibres will try to recover from the strain of being twisted. a hot-draw zone)  before the heating/twisting/cooling zone, POY yarns could then be utilised, giving better process economics and product variety in terms of bulk and stretch, depending on the pre-drawing; the yarn being referred to as a draw-textured yarn or DTY. Of input to output speed is termed the overfeed turbulent flow to difference between air textured yarn and draw textured yarn.
