difference between air textured yarn and draw textured yarn

It offers a fresh new … Another type of friction twisting device used is based on driven cross-belts. 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. 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. 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% '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. 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? %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 . {dpf}, the most popular yarns being more towards 1dpf or finer. textured yarn; bulky with considerable stretch (elongation or Twist? Usually 18% to 30% overfeed may be applied, depending on end-use requirements; parallel yarns are commonly used cut pile plush fabrics. E … DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat … Warp Knitting Air Textured Yarns Fabrics have been satisfactorily knit. 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. Texturing of Thermoplastic Continuous Filament? lengths would become separated, and would form a profusion of different sizes of entangled loops as they exit the jet to become the ATY. Get info of suppliers, manufacturers, exporters, traders of Textured Yarn for buying in India. However, air-textured yarn (ATY) has millions of small loops that offer a distinct look and feel. Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to Page 2 of 17 give … The three-dimensional crimp is permanently set by the heat. Generally high-pressure steam is known to be cheaper to produce than compressed air. An example of the set-DTY process is illustrated by Fig.7. However, where it is required that DTYs have relatively low Twist? DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. DTY yarn can be in Semi Dull or Bright or Triloble … This means that within a short time of starting the twisting process, Z-Twist? The rotation of the pin is effected by a driven disc assembly. If you would count the twist in both … Dependences of air textured polypropylene yarn properties on the yarn structure and air pressure in a texturing jet. McIntyre, J.E., and Daniels, P.N. The decrease of loop density in the case of air-jet textured yarns may be due to smaller loops. This type of application field is common to both flat and textured yarn. 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. texturing the reader is referred to [70], Fig.4 Illustration of the False Twisting Action, Fig.5 Illustration of False-Twist? Loop size and loop stability are important factors, especially for finer detex/denier yarns. Inside, the tube yarn comes underFig. Fibres & Textiles in Eastern Europe, 17(3), 48-50. Air-textured yarn (ATY) is an excellent substitute for the synthetic hand of false twist textured Yarn. When the POY is drawn and Twisted at the same time, the end product obtained is a draw textured yarn. 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. This is the false-twisting action as Fig 4 illustrates. Both may be comprised of one or more POY. By including a mechanical drawing stage(i.e. winding tension produce yarn with higher phys. 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. Yarns should be textured with minimum overfeed to also minimize plucking. Worsted is a hyponym of wool. 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. 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 … March 1999 ; Indian Journal of Fibre and Textile Research 24(1):16-20; Authors: V. K. Kothari. 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? Other articles where Textured yarn is discussed: man-made fibre: Texturing: Texturing is the formation of crimp, loops, coils, or crinkles in filaments. The elasticity can be obviously felt when pulling the two ends of the high elastic yarn. Spinning speeds between 3000 m/min to 4000m/min provides a partially oriented yarn which later requires draw of two during the draw texturizing. Core effect yarns are produced with two main components; core and the effect yarns. There are small wool fibers with different lengths around the yarn. texturing FDY/FOY yarns were texturised using a rotating pin as the false-Twist? Over the years, developments in air jet texturing have been related to the developments in nozzle design. After spinning and drawing, a slight intermingling is given to the flat yarn to facilitate the easy post spinning processes[2]. texturing requires the filaments to be initially heated above their Tg, the process is only suitable for thermoplastic polymeric  filaments. Air consumption is one significant cost factor in the process which must be kept as low as possible. Polyester Drawn Textured Yarn (Polyester DTY) Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. The twist on the left hand side remains. From here the yarn is fed to Shaft 2. 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. Bulk Continuous Filament? There is no universal nozzle capable of processing any supply yarn … 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. The fabric woven with it has a cotton feeling. If in the main drawing stage, the draw ratio is cyclically varied from high to low, while the Twist? 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. is referred to as S-Twist? Although CF yarns of virtually any polymer can be air-jet textured, the number of filaments and the dtex/denier per Filament? and the term false Twist?, and how the latter is produced. Air-jet texturing is one of the most versatile methods known to convert flat syntheticfilament yarns to textured yarns. It was built in 1969 as a result of vision of its founder Sh. 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 yarn is also constantly being twisted at the location X by some device, as its length moves through the distance AB. Wraps per inch for each yarn weight is the number of times you can wrap the yarn around one inch of a ruler. In air-jet texturing, filament yarns are fed over a tiny blast of air that forces the … 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. DTY: : Draw texturing yarn/ stretch textured yarn. Fig.7 Illustration of the set-DTY process. 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 … Simultaneously, the yarn length present within the zone XB will receive a counter clockwise torque, inserting S-Twist?. 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. The difference is that one yarn has been twisted into the opposite direction of the other yarn. Dyed yarn: It is formed by dyeing the yarn through a dyeing process, which is first spinning and then dyeing. Textured Filament? 1. With this development yarns from finer denier to extremely coarse denier can be textured. inside the jet. and Spun Yarns”, Woven Cloth Construction, pub.

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 objective of this research work was to investigate the use of steam as a substitute fluid for air in spun-like textured yarn manufacturing. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? Instability of air-jet tex­ tured yarns also first decreases and then increases with the increasing shrinkage difference. 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 … On the contrary, it is low elastic yarn. bulk, higher instability, lower tenacity, and higher elongation. FDY: Fully drawn yarn. The first type is called parallel yarns and the second type core effect yarns, and Fig.9 illustrates the production of both. Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of Physical properties of drawn yarns and textured yarns were reduced w ith increasing of OPP fraction. Similar as in the tangling of yarns the center of the ATY becomes randomly braided. will be present as it leaves. 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. 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. 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. Finishing Fabrics Containing Air Jet Textured Yarns Relaxation … Kayavlon is exporting FDY yarns from India, China,Malaysia, Thailand DTY yarn can be in Semi Dull or Bright or Triloble Bright … 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. Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. Mar 21, 2018 DTY: : Draw texturing yarn/ stretch textured yarn. What is Fully Oriented Yarn (FOY)? — Digital misty gray: PANTONE 13-4303TGP — In our factory, we can manufacture yarn with this color as well. General polyester high elastic yarn or low elastic yarn are not available. The difference between colored spinning and dyed yarn Is the dyed yarn colored spinning? Basically, the Filament? The heated yarn is passed between a pair of geared wheels or some similar device (gear crimping). What's the difference between DTY and FDY ? air-jet textured. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? Polyester (DTY) Drawn Textured Yarn yarn is obtained when Polyester POY is simultaneously twisted and drawn. What's the difference between DTY and FDY ? 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 color No is ZD7427 for polyester draw textured yarn and spandex covered yarn. ATY Air Textured Yarn, similar to cotton in appearance. 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. 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. lengths. Robinson, A.T.C and Marks, R.,  Chapter 1, p1, “Yarns and Their Characteristics: Continuous-Filament? For more in-depth study of the principles of false-Twist? The air-textured line manufactured by Sanathan Textiles is an excellent example that depicts how different yarns can be combined … texturing and air-jet texturing, the former being the dominant. 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.
