See Fig.6. 6. 6 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. loss increases with both factors. 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. 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 DTY yarn can be in Semi Dull or Bright or Triloble Bright … In addition, the pin-twister may be replaced with a friction-twisting device [71]. The drawing in my stretch yarn pageshows a running yarn in a false twisting machine. Smaller loops are more stable and give a better bulkiness than larger loops. 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 … When the POY is drawn and Twisted at the same time, the end product obtained is a draw textured yarn. yarns find applications in a wide range of technical end uses. Bicomponent Process: with this method the texture is obtained by twisting to together filaments of high and low potential shrinkage. Similarly with counter clockwise the Twist? There are basically 2 types of yarns which can be produced with air texturing. Should the yarn break, the twisted yarn on the left hand side also goes to waste. texturing process it is necessary to first consider the meaning of real Twist? 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 Yarns based on Poly(trimethylene trerephthalete)”, Chemical Fibres International, 47, 72-74, 1997. textured or air textured yarn. by Marcel Dekker, 1998. DTY Elastic Yarn can be divided into high elastic yarn and low elastic 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. Dependences of air textured polypropylene yarn properties on the yarn structure and air pressure in a texturing jet. If you would count the twist in both … The difference is that one yarn has been twisted into the opposite direction of the other yarn. Air-jet texturing of draw-textured yarns. Robinson, A.T.C and Marks, R.,  Chapter 1, p1, “Yarns and Their Characteristics: Continuous-Filament? 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 . In Fig32, the drawing zones for both yarn types have a heating element, which may be a heated pin, godet or plate. 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. To assist the loop formation, the filaments are wetted prior to entering the jet, by either Spraying? in the clockwise direction, the yarn length present within the zone AX, inserting Z-Twist?. Another type of friction twisting device used is based on driven cross-belts. Similar as in the tangling of yarns the center of the ATY becomes randomly braided. This heating stage gives an additional heat-setting treatment which reduces the intrinsic Elasticity? 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. The decrease of loop density in the case of air-jet textured yarns may be due to smaller loops. Physical properties of drawn yarns and textured yarns were reduced w ith increasing of OPP fraction. In this device the compressed air has a spiralling turbulent flow to the outlet, the loose Filament? 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 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. The yarn is also constantly being twisted at the location X by some device, as its length moves through the distance AB. Reimschuessel, H;  Chapter 2 “Polyamide Fibres, p.144, in Handbook of Fibre Chemistry, Edited by Lewin, M; pub. 6. McIntyre, J.E., and Daniels, P.N. Note that in the case of core effect type yarns, the two yarn paths must have their own drawing zone and therefore heating element. ester (DTY) Drawn Textured Yarn (DTY)Polyester DTY is obtained when Polyester POY is simultaneously twisted and drawn. The following are some examples, http://www.technica.net/NF/NF1/efibreptt.htm, http://www.swicofil.com/setilawidnaupbt.html, http://www.polda.com/products.html#_Applications, http://www.fibre2fashion.com/textile-market-watch/company-brief/trevira/, http://www.fibtex.lodz.pl/file-Fibtex_(trrd5d7ln5mizux7).pdf-FTEE_74_48.pdf, http://www.amitechindustries.com/products.html, Copyright © 2020 Textile Centre of Excellence 3485552Website Developed by Rippleffect, Textile Centre of Excellence, Textile House, Red Doles Lane, Huddersfield, HD2 1YF texturing FDY/FOY yarns were texturised using a rotating pin as the false-Twist? Basically, the Filament? The new substitute product holds the potential for competitive advantage, lower manufacturing costs and streamlined manufacturing capabilities. Has nothing to do with the production process, but now widely circulated, will it as a symbol of spin-draw … 9. Page 2 of 17 give greater bulk, higher stretch and more pleasing aesthetics. 4, … The stuffer-box method is a fast and inexpensive method for carpeting 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. E … 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. After the false twisting, the DTY passes through the additional heating zone to become a set-DTY. 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. The heating element is essential for polyester POY, but nylon and polypropylene POY may be cold drawn. What's the difference between DTY and FDY ? One Heater DTY is normally woolly & more stretchable as compared to DTY with two Heaters. There is also pronounced effect of draw ratio and D/Y ratio shown on the textured yarn structure and properties. device. extension, but retain a high bulk, an additional heating stage is incorporated after the roller-pair B. 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 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. Air texturing of a yarn is one of the most versatile methods of yarn texturing as it can combine type of filament Yarn together. inside the jet. The Filament? usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? 1. 3. However, air-textured yarn (ATY) has millions of small loops that offer a distinct look and feel. Despite the fact that false-Twist? POY are preferred for air jet textured yarns largely because they are less expensive than FOY. 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. Although CF yarns of virtually any polymer can be air-jet textured, the number of filaments and the dtex/denier per Filament? It suggests that the increase of effect-yarn draw ratio increases the level of … 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 … There are small wool fibers with different lengths around the yarn. See Fig 9. This type of application field is common to both flat and textured yarn. The technical specifications of draw textured yarn have made it ideal for a wide range of applications as it can be moulded in several ways as well. DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat … The three-dimensional crimp is permanently set by the heat. texturing requires the filaments to be initially heated above their Tg, the process is only suitable for thermoplastic polymeric  filaments. 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. The DP5-T DIGICONE® fastflex™ air texturing machine is designed for the flexible production of high quality air jet textured yarns.

We will show you the difference between a parallel and a Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted & drawn. The individual filaments are compacted by the air … 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. inserted; Twist? Mar 21, 2018. The difference between colored spinning and dyed yarn Is the dyed yarn colored spinning? 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. With this development yarns from finer denier to extremely coarse denier can be textured. Bulk Continuous Filament? will be present as it leaves. The fabric woven with it has a cotton feeling. During the earlier years of false-Twist? 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 page will explain how ATY is produced and where it is used. Vijay Kumar Yadav. Air consumption is one significant cost factor in the process which must be kept as low as possible. Instability of air-jet textured yarns also first decreases and then increases with the increasing shrinkage difference. %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 . 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. 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. 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. 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. To describe the basics of the false 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. Figure 3: Application of Intermingling While Spinning. Dyed yarn: It is formed by dyeing the yarn through a dyeing process, which is first spinning and then dyeing. 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,. bulk, higher instability, lower tenacity, and higher elongation. Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of What's the difference between DTY and FDY ? Air textured yarn is very bulky with permanent crimps and loops. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to Page 2 of 17 give … Toner, Masterbatch and Liquid Masterbatch, Copyright © Shandong Jiamei Fiber Technology Co., Ltd. All Rights Reserved. A ratio > 1, of input to output speed is termed the overfeed. Textiles Terms & Definitions, Compiled by The Textile Institute Textile Terms and Definitions Committee, Ed. The heated yarn is passed over a knife edge (edge crimping). This means that within a short time of starting the twisting process, Z-Twist? 2. Air jet textured yarns are a spun look like alternative to the more synthetic hand of false twist textured yarns. {dpf}, the most popular yarns being more towards 1dpf or finer. 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. Draw Textured Yarn … ATY Air Textured Yarn, similar to cotton in appearance. are very important; a high number of filaments with a low detex/denier per Filament? Texturing of Thermoplastic Continuous Filament? This study is related to production and testing of air covered yarn from polyester and lycra on air covering machine. Fig.7 Illustration of the set-DTY process. 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. Filament?-yarn.html">http://www.textileglossary.com/terms/Filament?-yarn.html    Jan2012, 5.       http://www.miniknittingstuff.com/yarn2.htm  Jan2012. Loop frequency, loop dimensions, loop stability and physical bulk are the important characteristics of air textured yarns. lengths would become separated, and would form a profusion of different sizes of entangled loops as they exit the jet to become the ATY. 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. Therefore, if a yarn end is held outside the tube and cut, it would go inside the tube on passing compressed air. Yarns should be textured with minimum overfeed to also minimize plucking. (BCF) Technology. General polyester high elastic yarn or low elastic yarn are not available. The yarn is simultaneously twisted and drawn. Free listing for companies. Get info of suppliers, manufacturers, exporters, traders of Textured Yarn for buying in India. Where is the difference between ATY Yarn and DTY Yarn ? 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. Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to . 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]. 10.

Abhay Trading Company has emerged as one of Leading Yarn Suppliers for manufacturers and dealers in Hosiery Industries. It doesn't matter what size or width your ruler is as this metric measures the thickness of the yarn rather than the length. 4346552 Bulky textured multifilament yarn 1982-08-31 Negishi et al. 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. This will depend on the fibre stiffness (torsional modulus) and the amount of Twist? Interlacing of filaments in the jet can cause the loops to be locked into the yarn so that any further twisting is unnecessary. In air-jet texturing, filament yarns are fed over a tiny blast of air that forces the … Draw textured yarn (DTY) and air-textured yarn are both made from partially oriented yarn (POY). Therefore a variety of air-texturing jets are available to cover the different ranges of dpf. 176 elongation at break, than on breaking force. It offers a fresh new … Rarely are yarns with a higher than 3.3dtex (3 denier) per Filament? texturing gives CF yarns a more natural feel bulk and stretch, their uniform geometry lacks the natural appearance of staple-spun yarns.
