DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat … Basically, the Filament? Although false-Twist? Currently, the practice is to use between 1.1 and 2.2 detex (1 and 2 denier) per Filament? ATY Air Textured Yarn, similar to cotton in appearance. However, air-textured yarn (ATY) has millions of small loops that offer a distinct look and feel. General polyester high elastic yarn or low elastic yarn are not available. Another type of friction twisting device used is based on driven cross-belts. Loop size and loop stability are important factors, especially for finer detex/denier yarns. ATY Air Textured Yarn, similar to cotton in appearance. Air-jet texturing method. So, air out side the tube with relatively higher pressure, rushes into the tube. McIntyre, J.E., and Daniels, P.N. Textured Filament? 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. Find here online price details of companies selling Textured Yarn. Similarly with counter clockwise the Twist? When Twist? The process used for achieving this staple-fibre like yarn is called “Texspun” developed by the machine manufacturer Barmag [75]. 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. Vijay Kumar Yadav. inserted; Twist? This is an assembly of overlapping discs which enables the CF yarn to be directly friction twisted, replacing the need for the hollow spindle. The Filament? The Textile Institute, 1993. 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 one device will therefore at any instant in time effectively Twist? Effect of process variables on bulk In zone XB, the S-Twist? 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. 9. 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. 9 Processes for Parallel and Core Effect ATY. On the contrary, it is low elastic yarn. The air-textured line manufactured by Sanathan Textiles is an excellent example that depicts how different yarns can be combined … 1. This will depend on the fibre stiffness (torsional modulus) and the amount of Twist? Air consumption is one significant cost factor in the process which must be kept as low as possible. 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. 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. After spinning and drawing, a slight intermingling is given to the flat yarn to facilitate the easy post spinning processes[2]. texturing the reader is referred to [70], Fig.4 Illustration of the False Twisting Action, Fig.5 Illustration of False-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. The individual filaments are compacted by the air … The fabric woven with it has a cotton feeling. Rarely are yarns with a higher than 3.3dtex (3 denier) per Filament? 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. After the false twisting, the DTY passes through the additional heating zone to become a set-DTY. Therefore a variety of air-texturing jets are available to cover the different ranges of dpf. winding tension produce yarn with higher phys. The new substitute product holds the potential for competitive advantage, lower manufacturing costs and streamlined manufacturing capabilities. 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. Smaller loops are more stable and give a better bulkiness than larger loops. Page 2 of 17 give greater bulk, higher stretch and more pleasing aesthetics. texturing and air-jet texturing, the former being the dominant. Therefore, if a yarn end is held outside the tube and cut, it would go inside the tube on passing compressed air. In a very short time, the Z-Twist? Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to . Draw Textured Yarn … usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? 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. 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: … Air jet textured yarns are a spun look like alternative to the more synthetic hand of false twist textured yarns. What's the difference between DTY and FDY ? 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% In air-jet texturing, filament yarns are fed over a tiny blast of air that forces the … Core effect yarns are produced with two main components; core and the effect yarns. 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. With this development yarns from finer denier to extremely coarse denier can be textured. POY are preferred for air jet textured yarns largely because they are less expensive than FOY. These entangle as the filaments get pulled together by removal rollers, to deliver an air- textured CF yarn. air-jet textured. This heating stage gives an additional heat-setting treatment which reduces the intrinsic Elasticity? 10. 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 … 2. Air-jet texturing is one of the most versatile methods known to convert flat syntheticfilament yarns to textured yarns. The rotation of the pin is effected by a driven disc assembly. 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. High elastic … bulk, higher instability, lower tenacity, and higher elongation. remains in the yarn[1]. 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. 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,. It offers a fresh new … Both may be comprised of one or more POY. R. L; Pieters, R; and Morrison M. E; “Fundamentals of False-Twist? 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. 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. See Fig.6. The figure shows the melt-spinning of nylon POY, which is then transferred to the draw texturing process. 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. 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 (DTY) Drawn Textured Yarn yarn is obtained when Polyester POY is simultaneously twisted and drawn. Because the yarns are with-drawn slowly, they buckle and back up on themselves. Generally high-pressure steam is known to be cheaper to produce than compressed air. Fig. Mar 21, 2018 DTY: : Draw texturing yarn/ stretch textured yarn. Usually 18% to 30% overfeed may be applied, depending on end-use requirements; parallel yarns are commonly used cut pile plush fabrics. From here the yarn is fed to Shaft 2. 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? The color No is ZD7427 for polyester draw textured yarn and spandex covered yarn. 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. There is also pronounced effect of draw ratio and D/Y ratio shown on the textured yarn structure and properties. By including a mechanical drawing stage(i.e. The twist on the left hand side remains. To assist the loop formation, the filaments are wetted prior to entering the jet, by either Spraying? Warp Knitting Air Textured Yarns Fabrics have been satisfactorily knit. There are small wool fibers with different lengths around the yarn. High quality air jet textured yarns … The DP5-T DIGICONE® fastflex™ air texturing machine is designed for the flexible production of high quality air jet textured yarns. The difference is that one yarn has been twisted into the opposite direction of the other yarn. Draw textured yarn (DTY) is made from Partially Oriented Yarn(POY). Yarn preparation includes the addition of 3 - 4% wax emulsion after texturing to minimize plucking on beams. 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. The fabric woven with it has a cotton feeling. insertion is similarly varied, the textured yarn will have thick and thin places along its length. loss increases with both factors. 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? High elastic elongation is high elastic yarns. 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. Should the yarn break, the twisted yarn on the left hand side also goes to waste. being preferred. in the clockwise direction, the yarn length present within the zone AX, inserting Z-Twist?. Free listing for companies. The twisting is done with a friction device, such as a set of rotating … One Heater DTY is normally woolly & more stretchable as compared to DTY with two Heaters. The heating element is essential for polyester POY, but nylon and polypropylene POY may be cold drawn. Filament?-yarn.html">http://www.textileglossary.com/terms/Filament?-yarn.html    Jan2012, 5.       http://www.miniknittingstuff.com/yarn2.htm  Jan2012. Over the years, developments in air jet texturing have been related to the developments in nozzle design. 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. 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. What is Fully Oriented Yarn (FOY)? Bicomponent Process: with this method the texture is obtained by twisting to together filaments of high and low potential shrinkage. Mar 21, 2018. (BCF) Technology. What is the difference between S and Z twist: There is a little and a lot of difference. Instability of air-jet textured yarns also first decreases and then increases with the increasing shrinkage difference. Fig.6  Illustrations of False-Twisting Devices. The usual setting temperatures are 230 - 240 °C for finer polyester yarns. Fibres & Textiles in Eastern Europe, 17(3), 48-50. To describe the basics of the false Twist? 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. texturing gives CF yarns a more natural feel bulk and stretch, their uniform geometry lacks the natural appearance of staple-spun yarns. Toner, Masterbatch and Liquid Masterbatch, Copyright © Shandong Jiamei Fiber Technology Co., Ltd. All Rights Reserved. This study is related to production and testing of air covered yarn from polyester and lycra on air covering machine. 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 textured or air textured yarn. There are small wool fibers with different lengths around the yarn. 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. Get info of suppliers, manufacturers, exporters, traders of Textured Yarn for buying in India. What is the difference between S and Z twist: There is a little and a lot of difference. 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.
