Polyester Fully Drawn Yarn is abbrevated as Polyester FDY. Viewed from B, along the length BX, it will appear to turning counter clockwise. DTY yarn can be in Semi Dull or Bright or Triloble Bright … Dyed yarn: It is formed by dyeing the yarn through a dyeing process, which is first spinning and then dyeing. Texturing Principle. 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 … Fig. Dependences of air textured polypropylene yarn properties on the yarn structure and air pressure in a texturing jet. by Marcel Dekker, 1998. In this device the compressed air has a spiralling turbulent flow to the outlet, the loose Filament? The decrease of loop density in the case of air-jet textured yarns may be due to smaller loops. There are small wool fibers with different lengths around the yarn. 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. DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. Maker Filaments - Manufacturer & exporter of Fancy Air Textured Yarn. To describe the basics of the false Twist? Robinson, A.T.C and Marks, R.,  Chapter 1, p1, “Yarns and Their Characteristics: Continuous-Filament? Has nothing to do with the production process, but now widely circulated, will it as a symbol of spin-draw … DTY: : Draw texturing yarn/ stretch textured yarn. Draw Textured Yarn … 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. 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 There is no universal nozzle capable of processing any supply yarn … texturing the reader is referred to [70], Fig.4 Illustration of the False Twisting Action, Fig.5 Illustration of False-Twist? Similar as in the tangling of yarns the center of the ATY becomes randomly braided. present in the yarn length passing through the zone will increase to a maximum value and then decrease to zero. A third pair of rollers would then be used as the output rollers. The rotation of the pin is effected by a driven disc assembly. The properties of false-twist textured yarns in the aspects of crimp characteristic and tensile behavior depend mainly on the draw ratio and the D/Y ratio. Vijay Kumar Yadav. General polyester high elastic yarn or low elastic yarn are not available. 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. An example of this method is the taslam process; Air jet textured yarn. This type of application field is common to both flat and textured yarn. lengths would become separated, and would form a profusion of different sizes of entangled loops as they exit the jet to become the ATY. 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 elasticity can be obviously felt when pulling the two ends of the high elastic yarn. This will depend on the fibre stiffness (torsional modulus) and the amount of Twist? We will show you the difference between a parallel and a 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. There are small wool fibers with different lengths around the yarn. 4, … 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. Smaller loops are more stable and give a better bulkiness than larger loops. 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. Get info of suppliers, manufacturers, exporters, traders of Textured Yarn for buying in India. Fig.3. 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. 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? 4346552 Bulky textured multifilament yarn 1982-08-31 Negishi et al. High elastic elongation is high elastic yarns. What are the benefits of textured yarns? {dpf}, the most popular yarns being more towards 1dpf or finer. The heated yarn is passed between a pair of geared wheels or some similar device (gear crimping). Wraps per inch for each yarn weight is the number of times you can wrap the yarn around one inch of a ruler. 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]. Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. Similarly with counter clockwise the Twist? being preferred. Despite the fact that false-Twist? When POY is fed into the machine, the yarn has to be drawn. 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. Air jet Texturising: 3/26/2014DRAWING & TEXTURISING29 In this method of texturing, yarns led through the turbulent region of a air jet at a rate faster than if is drawn off on the far side of the jet, in the jet, the yarn structure is opened , loops are locked inside and others are locked on the surface of the yarn. 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. From here the yarn is fed to Shaft 2. Texturing of Thermoplastic Continuous Filament?

Air-jet texturing of draw-textured yarns. as the fibres will try to recover from the strain of being twisted. bulk, higher instability, lower tenacity, and higher elongation. FDY yarn is available at Kayavlon in 3 lustre - Semi-dull (SD), Bright (BR) and Trilobal Bright (TBR). Air jet textured yarns are a spun look like alternative to the more synthetic hand of false twist textured yarns. Yarns”, Journal of Rheology, 16, 3, 557-577, 1972. 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. 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? By including a mechanical drawing stage(i.e. 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. 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 . Fig.6  Illustrations of False-Twisting Devices. 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]. 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. It doesn't matter what size or width your ruler is as this metric measures the thickness of the yarn rather than the length. 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: … What's the difference between DTY and FDY ? Air Textured Yarn (ATY) Annual Events Careers Contact Us CSR Draw Textured Yarn (DTY) Dyeing Yarn Fully Drawn Yarn (FDY) Gallery Home Home Textiles Home-2 Infrastructure Management Mono Yarn Mother Yarn Overview imparted by the texturing process. When the process is started the twisted yarn on the right side is discarded to waste. 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. 176 elongation at break, than on breaking force. Mar 21, 2018 DTY: : Draw texturing yarn/ stretch textured yarn. Therefore, if a yarn end is held outside the tube and cut, it would go inside the tube on passing compressed air. So, air out side the tube with relatively higher pressure, rushes into the tube. Air-textured yarn (ATY) is an excellent substitute for the synthetic hand of false twist textured 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. Figure 3: Application of Intermingling While Spinning. E … 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 … 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. 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. Various techniques have been developed, therefore, to modify their appearance. One Heater DTY is normally woolly & more stretchable as compared to DTY with two Heaters. 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. Other articles where Textured yarn is discussed: man-made fibre: Texturing: Texturing is the formation of crimp, loops, coils, or crinkles in filaments. A spherical barrier is positioned close to the outlet orifice, so that as the compressed air exits it becomes a turbulent air flow. Find here online price details of companies selling Textured Yarn. Worsted is a hyponym of wool. What's the difference between DTY and FDY ? contraction  at low applied force) depending on the level of false twisting. 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. 2. Loop frequency, loop dimensions, loop stability and physical bulk are the important characteristics of air textured yarns. The process is particularly useful for the manufacture of nylon textured yarns having a linear density in the range of from about 10 dtex to about 50 dtex [72], Generally all thermoplastic multifilament yarns made from polyesters, nylons  and polypropylene can be converted into DTYs. With an axial jet, the compressed air is accelerated to the outlet while dragging the filaments along. 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 … After the false twisting, the DTY passes through the additional heating zone to become a set-DTY. Because the yarns are with-drawn slowly, they buckle and back up on themselves. Air texturing of a yarn is one of the most versatile methods of yarn texturing as it can combine type of filament Yarn together. The difference is that one yarn has been twisted into the opposite direction of the other yarn. 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. Finishing Fabrics Containing Air Jet Textured Yarns Relaxation … [13] Chuah, H. H. (2004). 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. The heated yarn is passed over a knife edge (edge crimping). However, air-textured yarn (ATY) has millions of small loops that offer a distinct look and feel. texturing process it is necessary to first consider the meaning of real Twist? yarns find applications in a wide range of technical end uses. 9. Core effect yarns are produced with two main components; core and the effect yarns. Currently, the practice is to use between 1.1 and 2.2 detex (1 and 2 denier) per Filament? 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). FDY: Fully drawn yarn. 57/209 4035879 Apparatus for producing texturized yarns 1977-07-19 Schippers 28/246 4034548 Process for the production of stretch-textured yarns and the term false Twist?, and how the latter is produced. Importantly, after the action of twisting the inserted Twist? — Digital misty gray: PANTONE 13-4303TGP — In our factory, we can manufacture yarn with this color as well. 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. |. In a very short time, the Z-Twist? 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. The yarn is knitted into a fabric, heat-set and unravelled (knit-deknit). texturing FDY/FOY yarns were texturised using a rotating pin as the false-Twist? Textured Filament? Brown, N.S; and Chuah,H.H, “Texturing of Textile Filament? loss increases with both factors. What is the difference between S and Z twist: There is a little and a lot of difference. Both may be comprised of one or more POY. As Fig 6 illustrates, the pin twister is a hollow spindle with a central pin positioned across the tubular interior. 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. Another type of friction twisting device used is based on driven cross-belts. and Spun Yarns”, Woven Cloth Construction, pub. If in the main drawing stage, the draw ratio is cyclically varied from high to low, while the Twist? On the contrary, it is low elastic yarn. 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. 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. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? lengths in the turbulent flow initially become separated, forming a profusion of loops of various sizes. Bicomponent Process: with this method the texture is obtained by twisting to together filaments of high and low potential shrinkage. 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. During the earlier years of false-Twist? Air consumption is one significant cost factor in the process which must be kept as low as possible. When Twist? Instability of air-jet textured yarns also first decreases and then increases with the increasing shrinkage difference. Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to Page 2 of 17 give … %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 .
