contraction  at low applied force) depending on the level of false twisting. The loops in ATY contribute to the bulk and loft of a fabric, whereas in DTY the even crimp in every filament creates the bulk and volume of a fabric. This page will explain how ATY is produced and where it is used. The difference is that one yarn has been twisted into the opposite direction of the other yarn. When POY is fed into the machine, the yarn has to be drawn. Where is the difference between ATY Yarn and DTY Yarn ? Loops are formed in individual filaments by over-feeding into a turbulent airstream (air-textured… 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). Kayavlon is exporting FDY yarns from India, China,Malaysia, Thailand loss increases with both factors. and Spun Yarns”, Woven Cloth Construction, pub. An example of this method is the taslam process; Air jet textured yarn. 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. 176 elongation at break, than on breaking force. Both, S and Z means real twist in a yarn. lengths to be textured are fed without tension into the jet ; this is achieved by ensuring that the speed at which they are fed into the jet is faster than the speed at which they leave the jet, the compressed air entering the jet can then act on the loose Filament? Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. The twist on the left hand side remains. winding tension produce yarn with higher phys. The elasticity can be obviously felt when pulling the two ends of the high elastic yarn. The major apparel applications for draw-twist are in knitted garments, especially double jersey for women’s outerwear and woven fabrics. Molecular weight and molecular weight distribution currently limit PP-BCF yarns to 900dtex and 3000 m/min. Polyester Fully Drawn Yarn is abbrevated as Polyester FDY. The DP5-T DIGICONE® fastflex™ air texturing machine is designed for the flexible production of high quality air jet textured yarns. This is the false-twisting action as Fig 4 illustrates. Mar 21, 2018 DTY: : Draw texturing yarn/ stretch textured yarn. In Fig32, the drawing zones for both yarn types have a heating element, which may be a heated pin, godet or plate. texturing requires the filaments to be initially heated above their Tg, the process is only suitable for thermoplastic polymeric  filaments. It was built in 1969 as a result of vision of its founder Sh. In the continuous production of filaments, after spinning the filaments … The air-textured line manufactured by Sanathan Textiles is an excellent example that depicts how different yarns can be combined … The three-dimensional crimp is permanently set by the heat. Should the yarn break, the twisted yarn on the left hand side also goes to waste. See Fig.6. 4. POY are preferred for air jet textured yarns largely because they are less expensive than FOY. When the POY is drawn and Twisted at the same time, the end product obtained is a draw textured yarn. Air textured yarn is very bulky with permanent crimps and loops. As Fig 6 illustrates, the pin twister is a hollow spindle with a central pin positioned across the tubular interior. Nylon (PA & PA6.6) of  600dtex,   3.3 – 5.6. dtex (3 -5 den)  filaments (compared with  11.1-16.7 /10-15 dpf) can be produced at productions speeds of up to 3500 m/min. — Digital misty gray: PANTONE 13-4303TGP — In our factory, we can manufacture yarn with this color as well. By including a mechanical drawing stage(i.e. 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. 10. 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 … Polyester Drawn Textured Yarn (Polyester DTY) Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. As Fig.32 shows, on leaving the air-jet, the textured yarn can be heat treated to increase the stability and  shrink the loops into a smaller size,. Keywords- False twist texturing, Draw … It was observed that Demir’s method is a practical and reliable way to compare the instability of air-jet textured yarns produced from the same raw material. The process used for achieving this staple-fibre like yarn is called “Texspun” developed by the machine manufacturer Barmag [75]. The decrease of loop density in the case of air-jet textured yarns may be due to smaller loops. DTY: : Draw texturing yarn/ stretch textured yarn. Air-textured yarn (ATY) is an excellent substitute for the synthetic hand of false twist textured Yarn. There is no universal nozzle capable of processing any supply yarn … The heating element is essential for polyester POY, but nylon and polypropylene POY may be cold drawn. As nouns the difference between worsted and wool is that worsted is yarn made from long strands of wool while wool is the hair of the sheep, llama and some other ruminants. bulk, higher instability, lower tenacity, and higher elongation. Similar as in the tangling of yarns the center of the ATY becomes randomly braided. “Acelon Chemicals & Fibre Corporation”, http://www.allproducts.com/textile/acelon/12-split_micro_filament.html. Page 2 of 17 give greater bulk, higher stretch and more pleasing aesthetics. E … 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. So, air out side the tube with relatively higher pressure, rushes into the tube. lengths in the turbulent flow initially become separated, forming a profusion of loops of various sizes. Maker Filaments - Manufacturer & exporter of Fancy Air Textured Yarn. 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. texturing the reader is referred to [70], Fig.4 Illustration of the False Twisting Action, Fig.5 Illustration of False-Twist? 'Textured Yarn' definition with manufacturers. 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. Inside, the tube yarn comes underFig. Textured Filament? DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. Note that in the case of core effect type yarns, the two yarn paths must have their own drawing zone and therefore heating element. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? Wraps per inch for each yarn weight is the number of times you can wrap the yarn around one inch of a ruler. 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. Here, the yarn is first drawn with a draw ratio of the order of 2.3 to 3.5 at a temperature of at least 50℃ ( Tg = 40oC), then subjected to simultaneously false twisting (friction disc device) , heating and a further drawing zone with a draw ratio of from 1.1 to 1.5. There is also pronounced effect of draw ratio and D/Y ratio shown on the textured yarn structure and properties. (BCF) Technology. and the term false Twist?, and how the latter is produced. textured yarns- nylon 66 air Textured yarns, draw Textured yarns, nylon yarns for hook & loop fastener, dupont Yarn, tactel yarns, polyester yarns, synthetic yarns, circular knitting yarns, warp knitting yarns, weaving Yarn for sportswear, lingeries, hosiery, Yarn dyeings, sewing thread, zipper sewing threads, label Yarn, bonded Yarn … 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). 3.       http://composite.about.com/library/glossary/c/bldef-c1269.htm  Jan 2012, 4. textured yarn; bulky with considerable stretch (elongation or Twist? To assist the loop formation, the filaments are wetted prior to entering the jet, by either Spraying? What is Fully Oriented Yarn (FOY)? lengths would become separated, and would form a profusion of different sizes of entangled loops as they exit the jet to become the ATY. 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. 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. being preferred. Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of finished products on a machine. Therefore, if a yarn end is held outside the tube and cut, it would go inside the tube on passing compressed air. DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. Smaller loops are more stable and give a better bulkiness than larger loops. An example of the set-DTY process is illustrated by Fig.7. Simultaneously, the yarn length present within the zone XB will receive a counter clockwise torque, inserting S-Twist?. lengths. Both may be comprised of one or more POY. Polyester Textured Filament Yarn (PTY) can be draw textured or air textured yarn. The heated yarn is passed over a knife edge (edge crimping). The speed of shaft 2 is always higher by the factor of the necessary draw ratio for the particular yarn and process. 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. insertion is similarly varied, the textured yarn will have thick and thin places along its length. Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted & drawn. One Heater DTY is normally woolly & more stretchable as compared to DTY with two Heaters. [13] Chuah, H. H. (2004). 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. ATY Air Textured Yarn, similar to cotton in appearance. An additional drawing zone using a hot-pin may be placed before the texturing stage, and used to impart irregular and repetitive changes to the filaments, so that after texturing the yarns display light and dark sections when dyed. Fig.3. 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). The usual setting temperatures are 230 - 240 °C for finer polyester yarns. Moreover, increasing of OPP fraction in blend, reduce crim p properties of textured yarn. extensions of 150 to 300%. 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 … is inserted into a CF yarn, starting at its free end, the filaments adopt a helical shape (or spiral) which may be a clockwise or counter clockwise spiral, in accordance with the direction of rotation of the twisting device. By including a mechanical drawing stage(i.e. in the clockwise direction, the yarn length present within the zone AX, inserting Z-Twist?. Rarely are yarns with a higher than 3.3dtex (3 denier) per Filament? Subjecting the resulting yarn to washing or steaming results in the differential shrinkage of the filaments to form the ulked profile. Since the advent of synthetic filament yarns, the preceding difficulties have been faced by textile industry and naturally several solutions have also been applied to overcome. Textiles Terms & Definitions, Compiled by The Textile Institute Textile Terms and Definitions Committee, Ed. It doesn't matter what size or width your ruler is as this metric measures the thickness of the yarn rather than the length. 2. yarns find applications in a wide range of technical end uses. The stuffer-box method is a fast and inexpensive method for carpeting yarn. This is because each length of yarn moving from zone AX into zone XB will become untwisted by the counter clockwise torque present in zone XB. The objective of this research work was to investigate the use of steam as a substitute fluid for air in spun-like textured yarn manufacturing. 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 … 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? Air texturing of a yarn is one of the most versatile methods of yarn texturing as it can combine type of filament Yarn together. Yarns”, Journal of Rheology, 16, 3, 557-577, 1972. 9. air-jet textured. Air-jet texturing of draw-textured yarns. There are small wool fibers with different lengths around the yarn. 5. If in the main drawing stage, the draw ratio is cyclically varied from high to low, while the Twist? The heated yarn is passed between a pair of geared wheels or some similar device (gear crimping). The material of high elastic yarn is generally nylon and polypropylene, etc, and low elastic yarn is generally nylon and polyester, etc. With the clockwise spiral, the inclination of the helix mirrors the inclination in the letter Z, and the Twist? Robinson, A.T.C and Marks, R.,  Chapter 1, p1, “Yarns and Their Characteristics: Continuous-Filament? FDY yarn is available at Kayavlon in 3 lustre - Semi-dull (SD), Bright (BR) and Trilobal Bright (TBR). 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: … Basically, the Filament? High elastic elongation is high elastic yarns. In this study yarns are produced with different level of air pressure i.e. Air consumption is one significant cost factor in the process which must be kept as low as possible. Currently, the practice is to use between 1.1 and 2.2 detex (1 and 2 denier) per Filament? Despite the fact that false-Twist? 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. 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]. With this development yarns from finer denier to extremely coarse denier can be textured. |. In a very short time, the Z-Twist? or dipping the yarn into a water bath; the water aids separation of the filaments and acts as a Lubricant? 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. 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% After the false twisting, the DTY passes through the additional heating zone to become a set-DTY. The color No is ZD7427 for polyester draw textured yarn and spandex covered yarn. With an axial jet, the compressed air is accelerated to the outlet while dragging the filaments along. Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to . On the contrary, it is low elastic yarn. 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. The one device will therefore at any instant in time effectively Twist? Fibres & Textiles in Eastern Europe, 17(3), 48-50. A ratio > 1, of input to output speed is termed the overfeed. 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. 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. Usually 18% to 30% overfeed may be applied, depending on end-use requirements; parallel yarns are commonly used cut pile plush fabrics. remains in the yarn[1]. Texturing Principle. A continuous filament yarn that has been processed to introduce durable crimps, coils, … 6. ATY Air Textured Yarn, similar to cotton in appearance. Worsted is a hyponym of wool. Highly stretchable yarns can be made by applying high levels of false-Twist?, resulting in Twist? {dpf}, the most popular yarns being more towards 1dpf or finer. 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. The difference between colored spinning and dyed yarn Is the dyed yarn colored spinning? Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of texturing process it is necessary to first consider the meaning of real Twist? There are basically 2 types of yarns which can be produced with air texturing. Air-jet textured yarns produced at const. 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. Texturing of Thermoplastic Continuous Filament? Abhay Jain. The figure depicts the situation where a CF yarn, nipped by two pairs of rollers at positions A and B is driven at a linear speed of Vd  m/min. Yarns should be textured with minimum overfeed to also minimize plucking. 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. Other articles where Textured yarn is discussed: man-made fibre: Texturing: Texturing is the formation of crimp, loops, coils, or crinkles in filaments. 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? is called Z-Twist?. imparted by the texturing process. This study is related to production and testing of air covered yarn from polyester and lycra on air covering machine. The specific difference between high elastic yarn and low elastic yarn is: compared with low elastic yarn, the swelling and bending state of the high elastic yarn is larger, more bending. 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. will be removed by the counter clockwise torque. Bicomponent Process: with this method the texture is obtained by twisting to together filaments of high and low potential shrinkage. Polyester (DTY) Drawn Textured Yarn yarn is obtained when Polyester POY is simultaneously twisted and drawn. Bulk Continuous Filament? Core effect yarns are produced with two main components; core and the effect yarns. 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. To describe the basics of the false Twist? The yarn is also constantly being twisted at the location X by some device, as its length moves through the distance AB. The fabric woven with it has a cotton feeling. textured or air textured yarn. Dyed yarn: It is formed by dyeing the yarn through a dyeing process, which is first spinning and then dyeing. 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… What is the difference between S and Z twist: There is a little and a lot of difference. DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat … The individual filaments are compacted by the air … are very important; a high number of filaments with a low detex/denier per Filament? Physical properties of drawn yarns and textured yarns were reduced w ith increasing of OPP fraction. 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. Find here online price details of companies selling Textured Yarn. The drawing in my stretch yarn pageshows a running yarn in a false twisting machine. extension of the DTY, and the yarn is said to be stabilised or a set-DTY. If the yarn were to be heated above the Tg [1] of the polymer while it is being Z-twisted in zone AX,  Fig.5, and then cooled before being untwisted in zone XB, the spiral shape of the individual filaments comprising the CF yarn would be retained, but the filaments would become free of the Twist?
