Despite the fact that false-Twist? 2. winding tension produce yarn with higher phys. Highly stretchable yarns can be made by applying high levels of false-Twist?, resulting in Twist? usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? The elasticity can be obviously felt when pulling the two ends of the high elastic yarn. 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. Dyed yarn: It is formed by dyeing the yarn through a dyeing process, which is first spinning and then dyeing. as the fibres will try to recover from the strain of being twisted. There are small wool fibers with different lengths around the yarn. yarns find applications in a wide range of technical end uses. 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. contraction  at low applied force) depending on the level of false twisting. textured yarn; bulky with considerable stretch (elongation or Twist? In … {dpf}, the most popular yarns being more towards 1dpf or finer. will remain in the yarn, since the Z-Twist? and the term false Twist?, and how the latter is produced. However, where it is required that DTYs have relatively low Twist? The twisting is done with a friction device, such as a set of rotating … Robinson, A.T.C and Marks, R.,  Chapter 1, p1, “Yarns and Their Characteristics: Continuous-Filament? A third pair of rollers would then be used as the output rollers. Brown, N.S; and Chuah,H.H, “Texturing of Textile Filament? Another type of friction twisting device used is based on driven cross-belts. It was built in 1969 as a result of vision of its founder Sh. 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. View full-text Article Worsted is a hyponym of wool. The heated yarn is passed between a pair of geared wheels or some similar device (gear crimping). 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 … 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. in the yarn length present in AX will increase to a constant value equal to Vd / Ns turns per metre. Viewed from B, along the length BX, it will appear to turning counter clockwise. A ratio > 1, of input to output speed is termed the overfeed. DTY yarn can be in Semi Dull or Bright or Triloble Bright … 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. extensions of 150 to 300%. Textured Filament? 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. From here the yarn is fed to Shaft 2. Yarns based on Poly(trimethylene trerephthalete)”, Chemical Fibres International, 47, 72-74, 1997. 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. Bulk Continuous Filament? in the clockwise direction, the yarn length present within the zone AX, inserting Z-Twist?. This heating stage gives an additional heat-setting treatment which reduces the intrinsic Elasticity? Core effect yarns are produced with two main components; core and the effect yarns. Molecular weight and molecular weight distribution currently limit PP-BCF yarns to 900dtex and 3000 m/min. One Heater DTY is normally woolly & more stretchable as compared to DTY with two Heaters. In the continuous production of filaments, after spinning the filaments … If you would count the twist in both … Kayavlon is exporting FDY yarns from India, China,Malaysia, Thailand “Acelon Chemicals & Fibre Corporation”, http://www.allproducts.com/textile/acelon/12-split_micro_filament.html. In a very short time, the Z-Twist? bulk, higher instability, lower tenacity, and higher elongation. 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 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 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 … Spinning speeds between 3000 m/min to 4000m/min provides a partially oriented yarn which later requires draw of two during the draw texturizing.

The color No is ZD7427 for polyester draw textured yarn and spandex covered yarn. With the clockwise spiral, the inclination of the helix mirrors the inclination in the letter Z, and the Twist? 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. 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). Both, S and Z means real twist in a yarn. 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. Similar as in the tangling of yarns the center of the ATY becomes randomly braided. Mar 21, 2018. Simultaneously, the yarn length present within the zone XB will receive a counter clockwise torque, inserting S-Twist?. extension of the DTY, and the yarn is said to be stabilised or a set-DTY. 'Textured Yarn' definition with manufacturers. Since false-Twist? usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? Therefore a variety of air-texturing jets are available to cover the different ranges of dpf. It offers a fresh new … 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. 3. Other articles where Textured yarn is discussed: man-made fibre: Texturing: Texturing is the formation of crimp, loops, coils, or crinkles in filaments. finishes and a yarn of 68trilobal filaments (2.44 dtex per filament) were textured. 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. Finishing Fabrics Containing Air Jet Textured Yarns Relaxation … Usually 18% to 30% overfeed may be applied, depending on end-use requirements; parallel yarns are commonly used cut pile plush fabrics. present in the yarn length passing through the zone will increase to a maximum value and then decrease to zero. So, air out side the tube with relatively higher pressure, rushes into the tube. The three-dimensional crimp is permanently set by the heat. Should the yarn break, the twisted yarn on the left hand side also goes to waste. 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. Generally high-pressure steam is known to be cheaper to produce than compressed air. Filament?-yarn.html">http://www.textileglossary.com/terms/Filament?-yarn.html    Jan2012, 5.       http://www.miniknittingstuff.com/yarn2.htm  Jan2012. 5. 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. Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of finished products on a machine. 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. Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. Air-jet texturing can be used to process FDY/FOY (to give an air- textured yarn – ATY) or with a pre-drawing stage in an integrated draw-texturing system to convert POY to a drawn-air textured yarn – DATY). Similarly with counter clockwise the Twist? The fabric woven with it has a cotton feeling. Loops are formed in individual filaments by over-feeding into a turbulent airstream (air-textured… 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% Polyester Fully Drawn Yarn is abbrevated as Polyester FDY. DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. will be removed by the counter clockwise torque. 4. The new substitute product holds the potential for competitive advantage, lower manufacturing costs and streamlined manufacturing capabilities. A continuous filament yarn that has been processed to introduce durable crimps, coils, … 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.

When the POY is drawn and Twisted at the same time, the end product obtained is a draw textured yarn. will be seen in the yarn as it runs into the twisting device, but no Twist? Hand, or … The two most popular textured yarn structures are draw-twist texturing and air-jet texturing. Air texturing of a yarn is one of the most versatile methods of yarn texturing as it can combine type of filament Yarn together. Importantly, after the action of twisting the inserted Twist? What is the difference between S and Z twist: There is a little and a lot of difference. In this device the compressed air has a spiralling turbulent flow to the outlet, the loose Filament? Various techniques have been developed, therefore, to modify their appearance. 6. 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. 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? 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. What's the difference between DTY and FDY ? device. texturing process it is necessary to first consider the meaning of real Twist? This study is related to production and testing of air covered yarn from polyester and lycra on air covering machine. Toner, Masterbatch and Liquid Masterbatch, Copyright © Shandong Jiamei Fiber Technology Co., Ltd. All Rights Reserved. However, air-textured yarn (ATY) has millions of small loops that offer a distinct look and feel. 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. 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. Abhay Trading Company has emerged as one of Leading Yarn Suppliers for manufacturers and dealers in Hosiery Industries. ATY Air Textured Yarn, similar to cotton in appearance. 6 lengths would become separated, and would form a profusion of different sizes of entangled loops as they exit the jet to become the ATY. Mar 21, 2018 DTY: : Draw texturing yarn/ stretch textured yarn. 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. Of the above methods briefly described, the more widely used are false-Twist? March 1999 ; Indian Journal of Fibre and Textile Research 24(1):16-20; Authors: V. K. Kothari. %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 . 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 … Air-jet textured yarns produced at const. The flat CF yarn passes down the tube and around the pin. Loop frequency, loop dimensions, loop stability and physical bulk are the important characteristics of air textured yarns. 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. Instability of air-jet tex­ tured yarns also first decreases and then increases with the increasing shrinkage difference. 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. 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. 9. The material of high elastic yarn is generally nylon and polypropylene, etc, and low elastic yarn is generally nylon and polyester, etc. texturing the reader is referred to [70], Fig.4 Illustration of the False Twisting Action, Fig.5 Illustration of False-Twist? Texturing of Thermoplastic Continuous Filament? By including a mechanical drawing stage(i.e. On the contrary, it is low elastic yarn. High quality air jet textured yarns … If in the main drawing stage, the draw ratio is cyclically varied from high to low, while the Twist? This means that within a short time of starting the twisting process, Z-Twist? 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. (BCF) Technology. Has nothing to do with the production process, but now widely circulated, will it as a symbol of spin-draw … texturing gives CF yarns a more natural feel bulk and stretch, their uniform geometry lacks the natural appearance of staple-spun yarns. Fig.7 Illustration of the set-DTY process. Effect of process variables on bulk is called Z-Twist?. Where is the difference between ATY Yarn and DTY Yarn ? 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. Moreover, increasing of OPP fraction in blend, reduce crim p properties of textured yarn. is referred to as S-Twist? 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]. Air jet textured yarns are a spun look like alternative to the more synthetic hand of false twist textured yarns. Textiles Terms & Definitions, Compiled by The Textile Institute Textile Terms and Definitions Committee, Ed. To assist the loop formation, the filaments are wetted prior to entering the jet, by either Spraying? In this study yarns are produced with different level of air pressure i.e. It suggests that the increase of effect-yarn draw ratio increases the level of … 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 insertion is similarly varied, the textured yarn will have thick and thin places along its length. Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of The yarn is simultaneously twisted and drawn. 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]. The twist on the left hand side remains. 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. texturing FDY/FOY yarns were texturised using a rotating pin as the false-Twist? 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. 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. The temperatures must be hot enough to ensure that the yarns are adequately treated. inserted; Twist? Find here online price details of companies selling Textured Yarn. air-jet textured. 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. With this development yarns from finer denier to extremely coarse denier can be textured. compaction resulting a false-Twist? 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. Currently, the practice is to use between 1.1 and 2.2 detex (1 and 2 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. extension, but retain a high bulk, an additional heating stage is incorporated after the roller-pair B. The DP5-T DIGICONE® fastflex™ air texturing machine is designed for the flexible production of high quality air jet textured yarns. To describe the basics of the false Twist? R. L; Pieters, R; and Morrison M. E; “Fundamentals of False-Twist? The drawing in my stretch yarn pageshows a running yarn in a false twisting machine. The yarn is knitted into a fabric, heat-set and unravelled (knit-deknit). Instability of air-jet textured yarns also first decreases and then increases with the increasing shrinkage difference. 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. will be present as it leaves. Inside, the tube yarn comes underFig. The heating element is essential for polyester POY, but nylon and polypropylene POY may be cold drawn. The heated yarn is passed over a knife edge (edge crimping). 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. After the false twisting, the DTY passes through the additional heating zone to become a set-DTY. These entangle as the filaments get pulled together by removal rollers, to deliver an air- textured CF yarn. ; see.
