To assist the loop formation, the filaments are wetted prior to entering the jet, by either Spraying? Reimschuessel, H;  Chapter 2 “Polyamide Fibres, p.144, in Handbook of Fibre Chemistry, Edited by Lewin, M; pub. Loop size and loop stability are important factors, especially for finer detex/denier yarns. The difference between colored spinning and dyed yarn Is the dyed yarn colored spinning? 3. When POY is fed into the machine, the yarn has to be drawn. In air-jet texturing, filament yarns are fed over a tiny blast of air that forces the … ester (DTY) Drawn Textured Yarn (DTY)Polyester DTY is obtained when Polyester POY is simultaneously twisted and drawn. The speed of shaft 2 is always higher by the factor of the necessary draw ratio for the particular yarn and process. textured yarn; bulky with considerable stretch (elongation or Twist? Various techniques have been developed, therefore, to modify their appearance. Should the yarn break, the twisted yarn on the left hand side also goes to waste. Both may be comprised of one or more POY. The flat CF yarn passes down the tube and around the pin. Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to Page 2 of 17 give … Dyed yarn: It is formed by dyeing the yarn through a dyeing process, which is first spinning and then dyeing. An example of the set-DTY process is illustrated by Fig.7. Loop frequency, loop dimensions, loop stability and physical bulk are the important characteristics of air textured yarns. Dependences of air textured polypropylene yarn properties on the yarn structure and air pressure in a texturing jet. FDY: Fully drawn yarn. Because the yarns are with-drawn slowly, they buckle and back up on themselves. 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]. Physical properties of drawn yarns and textured yarns were reduced w ith increasing of OPP fraction. Polyester Textured Filament Yarn (PTY) can be draw textured or air textured 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. Air-textured yarn (ATY) is an excellent substitute for the synthetic hand of false twist textured Yarn. 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 stuffer-box method is a fast and inexpensive method for carpeting yarn. 10. Yarns based on Poly(trimethylene trerephthalete)”, Chemical Fibres International, 47, 72-74, 1997. In a very short time, the Z-Twist? loss increases with both factors. textured or air textured yarn. View full-text Article Keywords- False twist texturing, Draw … When the process is started the twisted yarn on the right side is discarded to waste. Over the years, developments in air jet texturing have been related to the developments in nozzle design. texturing and air-jet texturing, the former being the dominant. 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.

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. Therefore a variety of air-texturing jets are available to cover the different ranges of dpf. 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. 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. finishes and a yarn of 68trilobal filaments (2.44 dtex per filament) were textured. [13] Chuah, H. H. (2004). 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 . The elasticity can be obviously felt when pulling the two ends of the high elastic yarn. air-jet textured. It doesn't matter what size or width your ruler is as this metric measures the thickness of the yarn rather than the length. What is the difference between S and Z twist: There is a little and a lot of difference. The twisting is done with a friction device, such as a set of rotating … R. L; Pieters, R; and Morrison M. E; “Fundamentals of False-Twist? FDY yarn is available at Kayavlon in 3 lustre - Semi-dull (SD), Bright (BR) and Trilobal Bright (TBR). A continuous filament yarn that has been processed to introduce durable crimps, coils, … Draw textured yarn (DTY) and air-textured yarn are both made from partially oriented yarn (POY). These entangle as the filaments get pulled together by removal rollers, to deliver an air- textured CF yarn. |. Hand, or … 6. The temperatures must be hot enough to ensure that the yarns are adequately treated. Both, S and Z means real twist in a yarn. See Fig 9. Abhay Jain. DTY yarn can be in Semi Dull or Bright or Triloble … Where is the difference between ATY Yarn and DTY Yarn ? Inside, the tube yarn comes underFig. extension of the DTY, and the yarn is said to be stabilised or a set-DTY. During the earlier years of false-Twist? is called Z-Twist?. [1] A fibre being a textile raw material, generally characterised by flexibility, fineness and a high ratio of length to thickness(diameter):- aspect ratio. present in the yarn length passing through the zone will increase to a maximum value and then decrease to zero. 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. DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. winding tension produce yarn with higher phys. 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. will remain in the yarn, since the Z-Twist?

Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to . lengths would become separated, and would form a profusion of different sizes of entangled loops as they exit the jet to become the ATY. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? 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. High quality air jet textured yarns … texturing the reader is referred to [70], Fig.4 Illustration of the False Twisting Action, Fig.5 Illustration of False-Twist? 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. 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. Both, S and Z means real twist in a yarn. The one device will therefore at any instant in time effectively Twist? 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.

By including a mechanical drawing stage(i.e. What's the difference between DTY and FDY ? Smaller loops are more stable and give a better bulkiness than larger loops. 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). 6. or dipping the yarn into a water bath; the water aids separation of the filaments and acts as a Lubricant? Robinson, A.T.C and Marks, R.,  Chapter 1, p1, “Yarns and Their Characteristics: Continuous-Filament? In zone XB, the S-Twist? usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? Of the above methods briefly described, the more widely used are false-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. 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). Air-jet texturing of draw-textured yarns. as the fibres will try to recover from the strain of being twisted. 2. The DP5-T DIGICONE® fastflex™ air texturing machine is designed for the flexible production of high quality air jet textured yarns. (BCF) Technology. 1. 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. 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. 7. The new substitute product holds the potential for competitive advantage, lower manufacturing costs and streamlined manufacturing capabilities. 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 In this device the compressed air has a spiralling turbulent flow to the outlet, the loose Filament? The material of high elastic yarn is generally nylon and polypropylene, etc, and low elastic yarn is generally nylon and polyester, etc. One of the most important advantages of textured yarn is that it gives good comfort as the result of the air entrapped between the interstices of the yarn… 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. Another type of friction twisting device used is based on driven cross-belts. However, where it is required that DTYs have relatively low Twist? Note that in the case of core effect type yarns, the two yarn paths must have their own drawing zone and therefore heating element. When Twist? The three-dimensional crimp is permanently set by the heat. 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. will be removed by the counter clockwise torque. To describe the basics of the false Twist? A spherical barrier is positioned close to the outlet orifice, so that as the compressed air exits it becomes a turbulent air flow. 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. March 1999 ; Indian Journal of Fibre and Textile Research 24(1):16-20; Authors: V. K. Kothari. Polyester Drawn Textured Yarn (Polyester DTY) Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. The yarn is simultaneously twisted and drawn. Therefore, if a yarn end is held outside the tube and cut, it would go inside the tube on passing compressed air. Page 2 of 17 give greater bulk, higher stretch and more pleasing aesthetics. Warp Knitting Air Textured Yarns Fabrics have been satisfactorily knit. 57/209 4035879 Apparatus for producing texturized yarns 1977-07-19 Schippers 28/246 4034548 Process for the production of stretch-textured yarns Similar as in the tangling of yarns the center of the ATY becomes randomly braided. 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. Abhay Trading Company has emerged as one of Leading Yarn Suppliers for manufacturers and dealers in Hosiery Industries. Get info of suppliers, manufacturers, exporters, traders of Textured Yarn for buying in India. This will depend on the fibre stiffness (torsional modulus) and the amount of Twist? and the term false Twist?, and how the latter is produced. The first type is called parallel yarns and the second type core effect yarns, and Fig.9 illustrates the production of both. Polyester (DTY) Drawn Textured Yarn yarn is obtained when Polyester POY is simultaneously twisted and drawn. So, air out side the tube with relatively higher pressure, rushes into the tube. What are the benefits of textured yarns? Mar 21, 2018. After the false twisting, the DTY passes through the additional heating zone to become a set-DTY. General polyester high elastic yarn or low elastic yarn are not available. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? What is Fully Oriented Yarn (FOY)? What's the difference between DTY and FDY ? DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. There are small wool fibers with different lengths around the yarn. 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? Keywords: Air-jet texturing, Filament feed'yam, Shrinkage potential, Textured yarn … 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. Polyester Fully Drawn Yarn is abbrevated as Polyester FDY. 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 … There is also pronounced effect of draw ratio and D/Y ratio shown on the textured yarn structure and properties. The yarn is knitted into a fabric, heat-set and unravelled (knit-deknit). From here the yarn is fed to Shaft 2. device. Similarly with counter clockwise the Twist? POY are preferred for air jet textured yarns largely because they are less expensive than FOY. Bulk Continuous Filament? [1] There may be a slight loss of Twist? As Fig 6 illustrates, the pin twister is a hollow spindle with a central pin positioned across the tubular interior. Viewed from B, along the length BX, it will appear to turning counter clockwise. 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. 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. and Spun Yarns”, Woven Cloth Construction, pub. 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]. Basically, the Filament? See Fig.6. The heated yarn is passed between a pair of geared wheels or some similar device (gear crimping). The decrease of loop density in the case of air-jet textured yarns may be due to smaller loops. Other articles where Textured yarn is discussed: man-made fibre: Texturing: Texturing is the formation of crimp, loops, coils, or crinkles in filaments. Interlacing of filaments in the jet can cause the loops to be locked into the yarn so that any further twisting is unnecessary. Despite the fact that false-Twist? A vortex –jet design can also be used. The drawing in my stretch yarn pageshows a running yarn in a false twisting machine. Draw textured yarn (DTY) is made from Partially Oriented Yarn(POY). Textured Filament? There is no universal nozzle capable of processing any supply yarn … There are small wool fibers with different lengths around the yarn. by Marcel Dekker, 1998. Moreover, increasing of OPP fraction in blend, reduce crim p properties of textured yarn. 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. 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. Instability of air-jet textured 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. 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. 5. If the yarn were to be heated above the Tg [1] of the polymer while it is being Z-twisted in zone AX,  Fig.5, and then cooled before being untwisted in zone XB, the spiral shape of the individual filaments comprising the CF yarn would be retained, but the filaments would become free of the Twist? 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. 4, … Textiles Terms & Definitions, Compiled by The Textile Institute Textile Terms and Definitions Committee, Ed. texturing FDY/FOY yarns were texturised using a rotating pin as the false-Twist? Fig.6  Illustrations of False-Twisting Devices. Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted & drawn. The air-textured line manufactured by Sanathan Textiles is an excellent example that depicts how different yarns can be combined … The heating element is essential for polyester POY, but nylon and polypropylene POY may be cold drawn. With the clockwise spiral, the inclination of the helix mirrors the inclination in the letter Z, and the Twist? The yarn is also constantly being twisted at the location X by some device, as its length moves through the distance AB. Air textured yarn is very bulky with permanent crimps and loops. Yarn preparation includes the addition of 3 - 4% wax emulsion after texturing to minimize plucking on beams. Texturing Principle. 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. 176 elongation at break, than on breaking force. Air-jet texturing is one of the most versatile methods known to convert flat syntheticfilament yarns to textured yarns. In addition, the pin-twister may be replaced with a friction-twisting device [71]. imparted by the texturing process. An example of this method is the taslam process; Air jet textured yarn. texturing gives CF yarns a more natural feel bulk and stretch, their uniform geometry lacks the natural appearance of staple-spun yarns. Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of 4. What is the difference between S and Z twist: There is a little and a lot of difference. 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. Although CF yarns of virtually any polymer can be air-jet textured, the number of filaments and the dtex/denier per Filament? If you would count the twist in both … It offers a fresh new … Figure 3: Application of Intermingling While Spinning. Has nothing to do with the production process, but now widely circulated, will it as a symbol of spin-draw … On the contrary, it is low elastic yarn. The individual filaments are compacted by the air … 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. 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: … One Heater DTY is normally woolly & more stretchable as compared to DTY with two Heaters. We will show you the difference between a parallel and a 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 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. Air jet textured yarns are a spun look like alternative to the more synthetic hand of false twist textured yarns. 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% and Twist? DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat … 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? Fibres & Textiles in Eastern Europe, 17(3), 48-50. contraction  at low applied force) depending on the level of false twisting. A ratio > 1, of input to output speed is termed the overfeed. ; see. 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. Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. are very important; a high number of filaments with a low detex/denier per Filament? A yarn comprising at least one textured core and one separately textured effect yarn, wherein the core yarn is covered periodically along the length with two or more helical wraps of the effect yarn to form a nubby thickening, the Toner, Masterbatch and Liquid Masterbatch, Copyright © Shandong Jiamei Fiber Technology Co., Ltd. All Rights Reserved. Rarely are yarns with a higher than 3.3dtex (3 denier) per Filament? Maker Filaments - Manufacturer & exporter of Fancy Air Textured Yarn. 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. A third pair of rollers would then be used as the output rollers. inside the jet. After spinning and drawing, a slight intermingling is given to the flat yarn to facilitate the easy post spinning processes[2]. The color No is ZD7427 for polyester draw textured yarn and spandex covered yarn. The figure shows the melt-spinning of nylon POY, which is then transferred to the draw texturing process. 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. 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. 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.
