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. Draw textured yarn (DTY) and air-textured yarn are both made from partially oriented yarn (POY). Polyester Fully Drawn Yarn is abbrevated as Polyester FDY. Generally high-pressure steam is known to be cheaper to produce than compressed air. To assist the loop formation, the filaments are wetted prior to entering the jet, by either Spraying? Abhay Trading Company has emerged as one of Leading Yarn Suppliers for manufacturers and dealers in Hosiery Industries. DTY yarn can be in Semi Dull or Bright or Triloble … The new substitute product holds the potential for competitive advantage, lower manufacturing costs and streamlined manufacturing capabilities. 1. Since false-Twist? Air-jet texturing method. Yarns”, Journal of Rheology, 16, 3, 557-577, 1972. 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. What is the difference between S and Z twist: There is a little and a lot of difference. Rarely are yarns with a higher than 3.3dtex (3 denier) per Filament? In this device the compressed air has a spiralling turbulent flow to the outlet, the loose Filament? Fibres & Textiles in Eastern Europe, 17(3), 48-50. A spherical barrier is positioned close to the outlet orifice, so that as the compressed air exits it becomes a turbulent air flow. By including a mechanical drawing stage(i.e. This page will explain how ATY is produced and where it is used. What is Fully Oriented Yarn (FOY)? The heated yarn is passed over a knife edge (edge crimping). Other articles where Textured yarn is discussed: man-made fibre: Texturing: Texturing is the formation of crimp, loops, coils, or crinkles in filaments. What are the benefits of textured yarns? Dyed yarn: It is formed by dyeing the yarn through a dyeing process, which is first spinning and then dyeing. inside the jet. So, air out side the tube with relatively higher pressure, rushes into the tube. See Fig.6. 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. What is Fully Oriented Yarn (FOY)? Subjecting the resulting yarn to washing or steaming results in the differential shrinkage of the filaments to form the ulked profile. Maker Filaments - Manufacturer & exporter of Fancy Air Textured Yarn. We have strong network in China, Taiwan, South Korea, Malaysia, Thailand, Indonesia, Mexico, Spain, Italy & various other countries for Nylon DTY.Nylon POY is used for manufacturing … 9. Keywords: Air-jet texturing, Filament feed'yam, Shrinkage potential, Textured yarn … There are small wool fibers with different lengths around the yarn. The air-textured line manufactured by Sanathan Textiles is an excellent example that depicts how different yarns can be combined … 6. 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? present in the yarn length passing through the zone will increase to a maximum value and then decrease to zero. extension, but retain a high bulk, an additional heating stage is incorporated after the roller-pair B. With an axial jet, the compressed air is accelerated to the outlet while dragging the filaments along. The material of high elastic yarn is generally nylon and polypropylene, etc, and low elastic yarn is generally nylon and polyester, etc. [13] Chuah, H. H. (2004). From here the yarn is fed to Shaft 2. Loop frequency, loop dimensions, loop stability and physical bulk are the important characteristics of air textured yarns. 4, … Both, S and Z means real twist in a yarn. The drawing in my stretch yarn pageshows a running yarn in a false twisting machine. in the clockwise direction, the yarn length present within the zone AX, inserting Z-Twist?. Texturing Principle. Despite the fact that false-Twist? Polyester Textured Filament Yarn (PTY) can be draw textured or air textured yarn. 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: … Instability of air-jet tex­ tured yarns also first decreases and then increases with the increasing shrinkage difference. device. FDY: Fully drawn yarn. Moreover, increasing of OPP fraction in blend, reduce crim p properties of textured yarn. Of the above methods briefly described, the more widely used are false-Twist? The production of parallel yarns involves one or more POY being fed into the air jet device with precisely the same overfeed for all the yarns used. texturing process it is necessary to first consider the meaning of real Twist? 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. 9 Processes for Parallel and Core Effect ATY. 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. Air-jet textured yarns produced at const. The fabric woven with it has a cotton feeling. Should the yarn break, the twisted yarn on the left hand side also goes to waste. as the fibres will try to recover from the strain of being twisted. FRICTION TEXTURED YARN We can produce between 70 denier and 450 denier with a variety flaments dull ,semi dull and dope dyed with differents colours and quantity . During the earlier years of false-Twist? Fig.6  Illustrations of False-Twisting Devices. Mar 21, 2018 DTY: : Draw texturing yarn/ stretch textured yarn. The color No is ZD7427 for polyester draw textured yarn and spandex covered yarn. High quality air jet textured yarns … Reimschuessel, H;  Chapter 2 “Polyamide Fibres, p.144, in Handbook of Fibre Chemistry, Edited by Lewin, M; pub. Abhay Jain. Has nothing to do with the production process, but now widely circulated, will it as a symbol of spin-draw … Figure 3: Application of Intermingling While Spinning. 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). 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. The yarn is knitted into a fabric, heat-set and unravelled (knit-deknit). Polyester (DTY) Drawn Textured Yarn yarn is obtained when Polyester POY is simultaneously twisted and drawn. R. L; Pieters, R; and Morrison M. E; “Fundamentals of False-Twist? Bicomponent Process: with this method the texture is obtained by twisting to together filaments of high and low potential shrinkage. The DP5-T DIGICONE® fastflex™ air texturing machine is designed for the flexible production of high quality air jet textured yarns. 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. 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. Vijay Kumar Yadav. 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. However, where it is required that DTYs have relatively low Twist? ; see. One Heater DTY is normally woolly & more stretchable as compared to DTY with two Heaters. 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. Currently, the practice is to use between 1.1 and 2.2 detex (1 and 2 denier) per Filament? usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? In addition, the pin-twister may be replaced with a friction-twisting device [71]. The twist on the left hand side remains. Yarn preparation includes the addition of 3 - 4% wax emulsion after texturing to minimize plucking on beams. 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? yarns find applications in a wide range of technical end uses. will remain in the yarn, since the Z-Twist? Simultaneously, the yarn length present within the zone XB will receive a counter clockwise torque, inserting S-Twist?. 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,. ester (DTY) Drawn Textured Yarn (DTY)Polyester DTY is obtained when Polyester POY is simultaneously twisted and drawn. Bulk Continuous Filament? Air-jet texturing is one of the most versatile methods known to convert flat syntheticfilament yarns to textured yarns. Air textured yarn is very bulky with permanent crimps and loops. A vortex –jet design can also be used. finishes and a yarn of 68trilobal filaments (2.44 dtex per filament) were textured. 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 … In air-jet texturing, filament yarns are fed over a tiny blast of air that forces the … Keywords- False twist texturing, Draw … Texturing of Thermoplastic Continuous Filament? 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. Note that in the case of core effect type yarns, the two yarn paths must have their own drawing zone and therefore heating element. Both, S and Z means real twist in a yarn. In Fig32, the drawing zones for both yarn types have a heating element, which may be a heated pin, godet or plate. 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 … Worsted is a hyponym of wool. After spinning and drawing, a slight intermingling is given to the flat yarn to facilitate the easy post spinning processes[2]. “Acelon Chemicals & Fibre Corporation”, http://www.allproducts.com/textile/acelon/12-split_micro_filament.html. The difference is that one yarn has been twisted into the opposite direction of the other yarn. Yarns based on Poly(trimethylene trerephthalete)”, Chemical Fibres International, 47, 72-74, 1997. 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. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? 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]. What's the difference between DTY and FDY ? There is also pronounced effect of draw ratio and D/Y ratio shown on the textured yarn structure and properties. Similarly with counter clockwise the Twist? Polyester Drawn Textured Yarn (Polyester DTY) Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. inserted; Twist? Smaller loops are more stable and give a better bulkiness than larger loops. are very important; a high number of filaments with a low detex/denier per Filament? being preferred. 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. See Fig 9. 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. What is the difference between S and Z twist: There is a little and a lot of difference. 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. The elasticity can be obviously felt when pulling the two ends of the high elastic yarn. Because the yarns are with-drawn slowly, they buckle and back up on themselves. 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. 10. texturing FDY/FOY yarns were texturised using a rotating pin as the false-Twist? The major apparel applications for draw-twist are in knitted garments, especially double jersey for women’s outerwear and woven fabrics. 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. We will show you the difference between a parallel and a 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. 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. Air texturing of a yarn is one of the most versatile methods of yarn texturing as it can combine type of filament Yarn together. There is no universal nozzle capable of processing any supply yarn … in the yarn length present in AX will increase to a constant value equal to Vd / Ns turns per metre. 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. 7. 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. extensions of 150 to 300%. Wraps per inch for each yarn weight is the number of times you can wrap the yarn around one inch of a ruler. and the term false Twist?, and how the latter is produced. For example, overfeeds of 8% core and 40% effect would be used for an apparel end-use such as nylon sportswear; while 120% effect yarn overfeed would be appropriate for upholstery fabrics, both domestic and car seat upholstery. This type of application field is common to both flat and textured yarn. It offers a fresh new … As Fig 6 illustrates, the pin twister is a hollow spindle with a central pin positioned across the tubular interior. The fabric woven with it has a cotton feeling. Brown, N.S; and Chuah,H.H, “Texturing of Textile Filament? The yarn is also constantly being twisted at the location X by some device, as its length moves through the distance AB. 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. By including a mechanical drawing stage(i.e. texturing the reader is referred to [70], Fig.4 Illustration of the False Twisting Action, Fig.5 Illustration of False-Twist? The figure shows the melt-spinning of nylon POY, which is then transferred to the draw texturing process. It suggests that the increase of effect-yarn draw ratio increases the level of … High elastic elongation is high elastic yarns. [1] A fibre being a textile raw material, generally characterised by flexibility, fineness and a high ratio of length to thickness(diameter):- aspect ratio. Yarns should be textured with minimum overfeed to also minimize plucking. With this development yarns from finer denier to extremely coarse denier can be textured. The heated yarn is passed between a pair of geared wheels or some similar device (gear crimping). %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 . This is the false-twisting action as Fig 4 illustrates. 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. bulk, higher instability, lower tenacity, and higher elongation. All types of continuous filament yarns (PES, PA, PP, Glass, etc.) In zone XB, the S-Twist? 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. 6. The Textile Institute, 1993. This study is related to production and testing of air covered yarn from polyester and lycra on air covering machine. The yarn is simultaneously twisted and drawn. lengths in the turbulent flow initially become separated, forming a profusion of loops of various sizes. The three-dimensional crimp is permanently set by the heat. (BCF) Technology. is referred to as S-Twist? compaction resulting a false-Twist? by Marcel Dekker, 1998. The twisting is done with a friction device, such as a set of rotating … 5. lengths would become separated, and would form a profusion of different sizes of entangled loops as they exit the jet to become the ATY. or dipping the yarn into a water bath; the water aids separation of the filaments and acts as a Lubricant? DTY: : Draw texturing yarn/ stretch textured yarn. 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.
