The three-dimensional crimp is permanently set by the heat. Interlacing of filaments in the jet can cause the loops to be locked into the yarn so that any further twisting is unnecessary. Draw textured yarn (DTY) is made from Partially Oriented Yarn(POY). This means that within a short time of starting the twisting process, Z-Twist? The yarn is knitted into a fabric, heat-set and unravelled (knit-deknit). A spherical barrier is positioned close to the outlet orifice, so that as the compressed air exits it becomes a turbulent air flow. as the fibres will try to recover from the strain of being twisted. Both, S and Z means real twist in a yarn. extension, but retain a high bulk, an additional heating stage is incorporated after the roller-pair B. High quality air jet textured yarns … Air-textured yarn (ATY) is an excellent substitute for the synthetic hand of false twist textured Yarn. What is Fully Oriented Yarn (FOY)? Texturing Principle. Simultaneously, the yarn length present within the zone XB will receive a counter clockwise torque, inserting S-Twist?. The difference between colored spinning and dyed yarn Is the dyed yarn colored spinning? 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? 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 Fig32, the drawing zones for both yarn types have a heating element, which may be a heated pin, godet or plate. 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. To describe the basics of the false 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. Has nothing to do with the production process, but now widely circulated, will it as a symbol of spin-draw … 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 new substitute product holds the potential for competitive advantage, lower manufacturing costs and streamlined manufacturing capabilities. Various techniques have been developed, therefore, to modify their appearance. Free listing for companies. Air jet textured yarns are a spun look like alternative to the more synthetic hand of false twist textured yarns. There is also pronounced effect of draw ratio and D/Y ratio shown on the textured yarn structure and properties. 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 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. Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. What is the difference between S and Z twist: There is a little and a lot of difference. compaction resulting a false-Twist? 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). There is no universal nozzle capable of processing any supply yarn … If in the main drawing stage, the draw ratio is cyclically varied from high to low, while the Twist? It was built in 1969 as a result of vision of its founder Sh. Investigation of the influence of effect-yarn draw and effect-yarn overfeed on texturing performance: comparison between air-jet and steam-jet textured yarn Ganemulle Lekamalage Dharmasri Wickramasinghe1* and Peter William Foster2 *Correspondence:

Currently, the practice is to use between 1.1 and 2.2 detex (1 and 2 denier) per Filament? In a very short time, the Z-Twist? Textiles Terms & Definitions, Compiled by The Textile Institute Textile Terms and Definitions Committee, Ed. The rotation of the pin is effected by a driven disc assembly. and the term false Twist?, and how the latter is produced. The Filament? 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. 10. The difference is that one yarn has been twisted into the opposite direction of the other 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. A continuous filament yarn that has been processed to introduce durable crimps, coils, ⦠is referred to as S-Twist? textured or air textured yarn. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp?

In zone XB, the S-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. 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. It offers a fresh new … 9. Maker Filaments - Manufacturer & exporter of Fancy Air Textured Yarn. The yarn is also constantly being twisted at the location X by some device, as its length moves through the distance AB. Keywords: Air-jet texturing, Filament feed'yam, Shrinkage potential, Textured yarn … lengths in the turbulent flow initially become separated, forming a profusion of loops of various sizes. DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat ⦠The material of high elastic yarn is generally nylon and polypropylene, etc, and low elastic yarn is generally nylon and polyester, etc. Highly stretchable yarns can be made by applying high levels of false-Twist?, resulting in Twist? The difference is that one yarn has been twisted into the opposite direction of the other yarn. The DP5-T DIGICONE® fastflex™ air texturing machine is designed for the flexible production of high quality air jet textured yarns. inserted; Twist? General polyester high elastic yarn or low elastic yarn are not available. 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. is called Z-Twist?. Air-jet texturing is one of the most versatile methods known to convert flat syntheticfilament yarns to textured yarns. 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 … March 1999 ; Indian Journal of Fibre and Textile Research 24(1):16-20; Authors: V. K. Kothari. 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. An example of this method is the taslam process; Air jet textured yarn. In addition, the pin-twister may be replaced with a friction-twisting device [71]. The fabric woven with it has a cotton feeling. E ⦠McIntyre, J.E., and Daniels, P.N. 6. 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. Bulk Continuous Filament? inside the jet. 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? In this device the compressed air has a spiralling turbulent flow to the outlet, the loose Filament? 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 … Textured Filament? 1. or dipping the yarn into a water bath; the water aids separation of the filaments and acts as a Lubricant? General polyester high elastic yarn or low elastic yarn are not available. Mar 21, 2018. 9 Processes for Parallel and Core Effect ATY. Mar 21, 2018 DTY: : Draw texturing yarn/ stretch textured yarn. 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% The figure shows the melt-spinning of nylon POY, which is then transferred to the draw texturing process. Hearle, J.W.S; Hollick, L; and Wilson, D.K, “Yarn Texturing Technology”, Woodhead Publishing Ltd, Chapter 1, p.1-13, 2001, 8. High elastic … 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. Viewed from B, along the length BX, it will appear to turning counter clockwise. DTY yarn can be in Semi Dull or Bright or Triloble Bright … 176 elongation at break, than on breaking force. A ratio > 1, of input to output speed is termed the overfeed. The heating element is essential for polyester POY, but nylon and polypropylene POY may be cold drawn. Should the yarn break, the twisted yarn on the left hand side also goes to waste. As Fig 6 illustrates, the pin twister is a hollow spindle with a central pin positioned across the tubular interior. Basically, the Filament? There are small wool fibers with different lengths around the yarn. present in the yarn length passing through the zone will increase to a maximum value and then decrease to zero. Toner, Masterbatch and Liquid Masterbatch, Copyright © Shandong Jiamei Fiber Technology Co., Ltd. All Rights Reserved. The elasticity can be obviously felt when pulling the two ends of the high elastic yarn. 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 … The two most popular textured yarn structures are draw-twist texturing and air-jet texturing. Because the yarns are with-drawn slowly, they buckle and back up on themselves. The first type is called parallel yarns and the second type core effect yarns, and Fig.9 illustrates the production of both. are very important; a high number of filaments with a low detex/denier per Filament? When the POY is drawn and Twisted at the same time, the end product obtained is a draw textured yarn. texturing and air-jet texturing, the former being the dominant. Yarns should be textured with minimum overfeed to also minimize plucking. An example of the set-DTY process is illustrated by Fig.7. 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. 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? FDY yarn is available at Kayavlon in 3 lustre - Semi-dull (SD), Bright (BR) and Trilobal Bright (TBR). Air textured yarn is very bulky with permanent crimps and loops. texturing requires the filaments to be initially heated above their Tg, the process is only suitable for thermoplastic polymeric filaments. 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. See Fig.6. Fig. 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 lengths. Usually 18% to 30% overfeed may be applied, depending on end-use requirements; parallel yarns are commonly used cut pile plush fabrics. finishes and a yarn of 68trilobal filaments (2.44 dtex per filament) were textured. 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 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). Therefore, if a yarn end is held outside the tube and cut, it would go inside the tube on passing compressed air. This is the false-twisting action as Fig 4 illustrates. 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. DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. The twist on the left hand side remains. By including a mechanical drawing stage(i.e. and 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. 3. http://composite.about.com/library/glossary/c/bldef-c1269.htm Jan 2012, 4. The color No is ZD7427 for polyester draw textured yarn and spandex covered yarn. This study is related to production and testing of air covered yarn from polyester and lycra on air covering machine. 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. A third pair of rollers would then be used as the output rollers. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? 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 DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. 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). What is Fully Oriented Yarn (FOY)? Hand, or … This heating stage gives an additional heat-setting treatment which reduces the intrinsic Elasticity? Over the years, developments in air jet texturing have been related to the developments in nozzle design. The Textile Institute, 1993. It doesn't matter what size or width your ruler is as this metric measures the thickness of the yarn rather than the length. Filament?-yarn.html">http://www.textileglossary.com/terms/Filament?-yarn.html Jan2012, 5. http://www.miniknittingstuff.com/yarn2.htm Jan2012. Dyed yarn: It is formed by dyeing the yarn through a dyeing process, which is first spinning and then dyeing. 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. View full-text Article Polyester Fully Drawn Yarn is abbrevated as Polyester FDY. Fig.7 Illustration of the set-DTY process. 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,. Inside, the tube yarn comes underFig. DTY: : Draw texturing yarn/ stretch textured yarn. When the process is started the twisted yarn on the right side is discarded to waste. On the contrary, it is low elastic yarn. remains in the yarn[1]. Air-jet texturing of draw-textured yarns. The temperatures must be hot enough to ensure that the yarns are adequately treated. By including a mechanical drawing stage(i.e. texturing gives CF yarns a more natural feel bulk and stretch, their uniform geometry lacks the natural appearance of staple-spun yarns. 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. These entangle as the filaments get pulled together by removal rollers, to deliver an air- textured CF yarn. What's the difference between DTY and FDY ? 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. The process used for achieving this staple-fibre like yarn is called “Texspun” developed by the machine manufacturer Barmag [75]. 6. The yarn is simultaneously twisted and drawn. Importantly, after the action of twisting the inserted Twist? will be seen in the yarn as it runs into the twisting device, but no Twist? In the continuous production of filaments, after spinning the filaments … air-jet textured. Moreover, increasing of OPP fraction in blend, reduce crim p properties of 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. Draw textured yarn (DTY) and air-textured yarn are both made from partially oriented yarn (POY). R. L; Pieters, R; and Morrison M. E; “Fundamentals of False-Twist? 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. When POY is fed into the machine, the yarn has to be drawn. Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of finished products on a machine. Similar as in the tangling of yarns the center of the ATY becomes randomly braided. The one device will therefore at any instant in time effectively Twist? 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 Both may be comprised of one or more POY. extensions of 150 to 300%. Figure 3: Application of Intermingling While Spinning. loss increases with both factors. ATY Air Textured Yarn, similar to cotton in appearance. |. 5. 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. Core effect yarns are produced with two main components; core and the effect yarns. Polyester Textured Filament Yarn (PTY) can be draw textured or air textured yarn. Note that in the case of core effect type yarns, the two yarn paths must have their own drawing zone and therefore heating element. 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. in the yarn length present in AX will increase to a constant value equal to Vd / Ns turns per metre. 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 drawing in my stretch yarn pageshows a running yarn in a false twisting machine. 'Textured Yarn' definition with manufacturers. will remain in the yarn, since the Z-Twist? For more in-depth study of the principles of false-Twist? Vijay Kumar Yadav. The stuffer-box method is a fast and inexpensive method for carpeting yarn. imparted by the texturing process. After spinning and drawing, a slight intermingling is given to the flat yarn to facilitate the easy post spinning processes[2]. 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. Worsted is a hyponym of wool. 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. The decrease of loop density in the case of air-jet textured yarns may be due to smaller loops. In this study yarns are produced with different level of air pressure i.e. 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… Instability of air-jet textured yarns also first decreases and then increases with the increasing shrinkage difference. A vortex –jet design can also be used. The heated yarn is passed over a knife edge (edge crimping). This page will explain how ATY is produced and where it is used. 2. This type of application field is common to both flat and textured yarn. 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. ATY Air Textured Yarn, similar to cotton in appearance. Generally high-pressure steam is known to be cheaper to produce than compressed air. 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. bulk, higher instability, lower tenacity, and higher elongation. 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. In … All types of continuous filament yarns (PES, PA, PP, Glass, etc.) Reimschuessel, H; Chapter 2 “Polyamide Fibres, p.144, in Handbook of Fibre Chemistry, Edited by Lewin, M; pub. 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. 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. Keywords- False twist texturing, Draw ⦠Instability of air-jet tex tured yarns also first decreases and then increases with the increasing shrinkage difference. Texturing of Thermoplastic Continuous Filament? by Marcel Dekker, 1998. 7. The air-textured line manufactured by Sanathan Textiles is an excellent example that depicts how different yarns can be combined … Fig.6 Illustrations of False-Twisting Devices. Similarly with counter clockwise the Twist? The twisting is done with a friction device, such as a set of rotating … in the clockwise direction, the yarn length present within the zone AX, inserting Z-Twist?. There are basically 2 types of yarns which can be produced with air texturing. {dpf}, the most popular yarns being more towards 1dpf or finer. 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? Get info of suppliers, manufacturers, exporters, traders of Textured Yarn for buying in India. Molecular weight and molecular weight distribution currently limit PP-BCF yarns to 900dtex and 3000 m/min. and Spun Yarns”, Woven Cloth Construction, pub. 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. textured yarn; bulky with considerable stretch (elongation or Twist? 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. Air-jet textured yarns produced at const. What's the difference between DTY and FDY ? 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. winding tension produce yarn with higher phys. ; see. lengths would become separated, and would form a profusion of different sizes of entangled loops as they exit the jet to become the ATY. %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 . (BCF) Technology. Smaller loops are more stable and give a better bulkiness than larger loops. Both, S and Z means real twist in a yarn. Loops are formed in individual filaments by over-feeding into a turbulent airstream (air-textured… Polyester (DTY) Drawn Textured Yarn yarn is obtained when Polyester POY is simultaneously twisted and drawn. Another type of friction twisting device used is based on driven cross-belts. 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. Subjecting the resulting yarn to washing or steaming results in the differential shrinkage of the filaments to form the ulked profile. Yarn preparation includes the addition of 3 - 4% wax emulsion after texturing to minimize plucking on beams. 6 3. The speed of shaft 2 is always higher by the factor of the necessary draw ratio for the particular yarn and process. Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to Page 2 of 17 give ⦠See Fig 9. Finishing Fabrics Containing Air Jet Textured Yarns Relaxation … 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.
