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. contraction at low applied force) depending on the level of false twisting. 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 The individual filaments are compacted by the air … 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. Keywords: Air-jet texturing, Filament feed'yam, Shrinkage potential, Textured yarn … In this study yarns are produced with different level of air pressure i.e. The major apparel applications for draw-twist are in knitted garments, especially double jersey for womenâs outerwear and woven fabrics. McIntyre, J.E., and Daniels, P.N. Polyester Fully Drawn Yarn is abbrevated as Polyester 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. Viewed from B, along the length BX, it will appear to turning counter clockwise. In Fig32, the drawing zones for both yarn types have a heating element, which may be a heated pin, godet or plate. present in the yarn length passing through the zone will increase to a maximum value and then decrease to zero. textured yarn; bulky with considerable stretch (elongation or Twist? Warp Knitting Air Textured Yarns Fabrics have been satisfactorily knit. 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. 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. 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… When the process is started the twisted yarn on the right side is discarded to waste. It was built in 1969 as a result of vision of its founder Sh. Both, S and Z means real twist in a yarn. Figure 3: Application of Intermingling While Spinning. This will depend on the fibre stiffness (torsional modulus) and the amount of Twist? Polyester (DTY) Drawn Textured Yarn yarn is obtained when Polyester POY is simultaneously twisted and drawn. Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of finished products on a machine. 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). There is also pronounced effect of draw ratio and D/Y ratio shown on the textured yarn structure and properties. in the clockwise direction, the yarn length present within the zone AX, inserting Z-Twist?. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? 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. Similar as in the tangling of yarns the center of the ATY becomes randomly braided. Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to Page 2 of 17 give â¦ The yarn is simultaneously twisted and drawn. Molecular weight and molecular weight distribution currently limit PP-BCF yarns to 900dtex and 3000 m/min. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? This is the false-twisting action as Fig 4 illustrates. 3. extensions of 150 to 300%. 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. However, where it is required that DTYs have relatively low Twist? Draw Textured Yarn … 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. Where is the difference between ATY Yarn and DTY Yarn ? 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 Yarn preparation includes the addition of 3 - 4% wax emulsion after texturing to minimize plucking on beams. will remain in the yarn, since the Z-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. Air jet textured yarns are a spun look like alternative to the more synthetic hand of false twist textured yarns. By including a mechanical drawing stage(i.e. The twisting is done with a friction device, such as a set of rotating … General polyester high elastic yarn or low elastic yarn are not available. Polyester Textured Filament Yarn (PTY) can be draw textured or air textured 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 … Loops are formed in individual filaments by over-feeding into a turbulent airstream (air-textured… What are the benefits of textured yarns? bulk, higher instability, lower tenacity, and higher elongation. ATY Air Textured Yarn, similar to cotton in appearance. will be removed by the counter clockwise torque. 9 Processes for Parallel and Core Effect ATY. Smaller loops are more stable and give a better bulkiness than larger loops. 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: … Effect of process variables on bulk Fig.6 Illustrations of False-Twisting Devices. Simultaneously, the yarn length present within the zone XB will receive a counter clockwise torque, inserting S-Twist?. 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? 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? will be present as it leaves. 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. Air texturing of a yarn is one of the most versatile methods of yarn texturing as it can combine type of filament Yarn together. 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. 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. Of the above methods briefly described, the more widely used are false-Twist? 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. There are small wool fibers with different lengths around the yarn. 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. 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. This heating stage gives an additional heat-setting treatment which reduces the intrinsic Elasticity? Although false-Twist? texturing the reader is referred to , Fig.4 Illustration of the False Twisting Action, Fig.5 Illustration of False-Twist? DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat â¦ 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. 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. Abhay Jain. 2. Textured Filament? 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? R. L; Pieters, R; and Morrison M. E; “Fundamentals of False-Twist? 'Textured Yarn' definition with manufacturers. Difference between maximum and minimum values of elongation of fabrics with S7 and S11 yarn in weft is 37 % Râ = 0.104638 %, when difference between maximum and minimum This type of application field is common to both flat and textured yarn.

March 1999 ; Indian Journal of Fibre and Textile Research 24(1):16-20; Authors: V. K. Kothari.  Chuah, H. H. (2004). â Digital misty gray: PANTONE 13-4303TGP â In our factory, we can manufacture yarn with this color as well. In zone XB, the S-Twist? extension, but retain a high bulk, an additional heating stage is incorporated after the roller-pair B. Because the yarns are with-drawn slowly, they buckle and back up on themselves. compaction resulting a false-Twist? When the POY is drawn and Twisted at the same time, the end product obtained is a draw textured yarn. Texturing Principle. remains in the yarn. When POY is fed into the machine, the yarn has to be drawn. extension of the DTY, and the yarn is said to be stabilised or a set-DTY. Another type of friction twisting device used is based on driven cross-belts. 9. If the yarn were to be heated above the Tg  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? finishes and a yarn of 68trilobal filaments (2.44 dtex per filament) were textured. The color No is ZD7427 for polyester draw textured yarn and spandex covered yarn. This page will explain how ATY is produced and where it is used. A spherical barrier is positioned close to the outlet orifice, so that as the compressed air exits it becomes a turbulent air flow. These entangle as the filaments get pulled together by removal rollers, to deliver an air- textured CF yarn. Draw textured yarn (DTY) and air-textured yarn are both made from partially oriented yarn (POY). texturing gives CF yarns a more natural feel bulk and stretch, their uniform geometry lacks the natural appearance of staple-spun yarns. Keywords- False twist texturing, Draw â¦ lengths would become separated, and would form a profusion of different sizes of entangled loops as they exit the jet to become the ATY. 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. 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. 6 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 … The two most popular textured yarn structures are draw-twist texturing and air-jet texturing. The stuffer-box method is a fast and inexpensive method for carpeting yarn. In the continuous production of filaments, after spinning the filaments … Subjecting the resulting yarn to washing or steaming results in the differential shrinkage of the filaments to form the ulked profile. 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:email@example.com 1Department of Textile and Clothing … Air-jet texturing method. It doesn't matter what size or width your ruler is as this metric measures the thickness of the yarn rather than the length. Various techniques have been developed, therefore, to modify their appearance. 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. View full-text Article The decrease of loop density in the case of air-jet textured yarns may be due to smaller loops. The difference is that one yarn has been twisted into the opposite direction of the other yarn. Fig.3. The usual setting temperatures are 230 - 240 °C for finer polyester yarns. However, air-textured yarn (ATY) has millions of small loops that offer a distinct look and feel. Interlacing of filaments in the jet can cause the loops to be locked into the yarn so that any further twisting is unnecessary. To describe the basics of the false Twist? is called Z-Twist?. See Fig 9. The Textile Institute, 1993. 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. In this device the compressed air has a spiralling turbulent flow to the outlet, the loose Filament? Both may be comprised of one or more POY. Usually 18% to 30% overfeed may be applied, depending on end-use requirements; parallel yarns are commonly used cut pile plush fabrics. Air-jet texturing is one of the most versatile methods known to convert flat syntheticfilament yarns to textured yarns. yarns find applications in a wide range of technical end uses. air-jet textured. 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. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp?

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% Air-textured yarn (ATY) is an excellent substitute for the synthetic hand of false twist textured Yarn. 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. There are small wool fibers with different lengths around the yarn. Generally high-pressure steam is known to be cheaper to produce than compressed air. The fabric woven with it has a cotton feeling. 6. The twist on the left hand side remains. Fig.7 Illustration of the set-DTY process. Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted & drawn. Kayavlon is exporting FDY yarns from India, China,Malaysia, Thailand texturing process it is necessary to first consider the meaning of real Twist? 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. Should the yarn break, the twisted yarn on the left hand side also goes to waste. 4346552 Bulky textured multifilament yarn 1982-08-31 Negishi et al. 1. Reimschuessel, H; Chapter 2 “Polyamide Fibres, p.144, in Handbook of Fibre Chemistry, Edited by Lewin, M; pub. 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. Fig. 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 textured yarns also first decreases and then increases with the increasing shrinkage difference. After the false twisting, the DTY passes through the additional heating zone to become a set-DTY. 10. 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. Although CF yarns of virtually any polymer can be air-jet textured, the number of filaments and the dtex/denier per Filament? 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 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. or dipping the yarn into a water bath; the water aids separation of the filaments and acts as a Lubricant?  There may be a slight loss of Twist? In a very short time, the Z-Twist? 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. textured or air textured yarn. The figure shows the melt-spinning of nylon POY, which is then transferred to the draw texturing process. See Fig.6. Mar 21, 2018. Air textured yarn is very bulky with permanent crimps and loops. Bulk Continuous Filament? An example of the set-DTY process is illustrated by Fig.7. 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. will be seen in the yarn as it runs into the twisting device, but no Twist? There are basically 2 types of yarns which can be produced with air texturing. Tel: 01484 346500 | Email: firstname.lastname@example.org, Texturing processes are essentially concerned with introducing bulkiness into continuous-, http://composite.about.com/library/glossary/c/bldef-c1269.htm, http://www.miniknittingstuff.com/yarn2.htm, http://www.allproducts.com/textile/acelon/12-split_micro_filament.html, http://www.polyspintex.com/ups/text06.htm, False twist textured yarns: Principles, processing and applications, Textured Yarn Technology: Production, properties, and processing. 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. From here the yarn is fed to Shaft 2. Both, S and Z means real twist in a yarn. The heated yarn is passed between a pair of geared wheels or some similar device (gear crimping). is referred to as S-Twist? Air consumption is one significant cost factor in the process which must be kept as low as possible. The heated yarn is passed over a knife edge (edge crimping). There is no universal nozzle capable of processing any supply yarn … 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. Instability of air-jet tex tured yarns also first decreases and then increases with the increasing shrinkage difference. 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. If in the main drawing stage, the draw ratio is cyclically varied from high to low, while the Twist? The drawing in my stretch yarn pageshows a running yarn in a false twisting machine. During the earlier years of false-Twist? With this development yarns from finer denier to extremely coarse denier can be textured. FDY: Fully drawn yarn. By including a mechanical drawing stage(i.e. Draw textured yarn (DTY) is made from Partially Oriented Yarn(POY). The rotation of the pin is effected by a driven disc assembly. 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. 176 elongation at break, than on breaking force. The temperatures must be hot enough to ensure that the yarns are adequately treated. The yarn is knitted into a fabric, heat-set and unravelled (knit-deknit). insertion is similarly varied, the textured yarn will have thick and thin places along its length. What is Fully Oriented Yarn (FOY)? Toner, Masterbatch and Liquid Masterbatch, Copyright © Shandong Jiamei Fiber Technology Co., Ltd. All Rights Reserved. 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]. ester (DTY) Drawn Textured Yarn (DTY)Polyester DTY is obtained when Polyester POY is simultaneously twisted and drawn. The new substitute product holds the potential for competitive advantage, lower manufacturing costs and streamlined manufacturing capabilities. The yarn is also constantly being twisted at the location X by some device, as its length moves through the distance AB. 5. The air-textured line manufactured by Sanathan Textiles is an excellent example that depicts how different yarns can be combined … Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. Note that in the case of core effect type yarns, the two yarn paths must have their own drawing zone and therefore heating element. FDY yarn is available at Kayavlon in 3 lustre - Semi-dull (SD), Bright (BR) and Trilobal Bright (TBR). 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. Since false-Twist? Wraps per inch for each yarn weight is the number of times you can wrap the yarn around one inch of a ruler. Worsted is a hyponym of wool. 57/209 4035879 Apparatus for producing texturized yarns 1977-07-19 Schippers 28/246 4034548 Process for the production of stretch-textured yarns Air-jet textured yarns produced at const. 4, â¦ A ratio > 1, of input to output speed is termed the overfeed.

Abhay Trading Company has emerged as one of Leading Yarn Suppliers for manufacturers and dealers in Hosiery Industries. Therefore, if a yarn end is held outside the tube and cut, it would go inside the tube on passing compressed air. Bicomponent Process: with this method the texture is obtained by twisting to together filaments of high and low potential shrinkage. loss increases with both factors. After spinning and drawing, a slight intermingling is given to the flat yarn to facilitate the easy post spinning processes. Filament?-yarn.html">http://www.textileglossary.com/terms/Filament?-yarn.html Jan2012, 5. http://www.miniknittingstuff.com/yarn2.htm Jan2012. Has nothing to do with the production process, but now widely circulated, will it as a symbol of spin-draw … General polyester high elastic yarn or low elastic yarn are not available. lengths in the turbulent flow initially become separated, forming a profusion of loops of various sizes. Similarly with counter clockwise the Twist? Maker Filaments - Manufacturer & exporter of Fancy Air Textured Yarn. Yarns”, Journal of Rheology, 16, 3, 557-577, 1972. by Marcel Dekker, 1998. To assist the loop formation, the filaments are wetted prior to entering the jet, by either Spraying? Finishing Fabrics Containing Air Jet Textured Yarns Relaxation … The speed of shaft 2 is always higher by the factor of the necessary draw ratio for the particular yarn and process. What's the difference between DTY and FDY ? 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,. 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 , Generally all thermoplastic multifilament yarns made from polyesters, nylons and polypropylene can be converted into DTYs. On the contrary, it is low elastic yarn. Page 2 of 17 give greater bulk, higher stretch and more pleasing aesthetics. Over a knife edge ( edge crimping ) or low elastic yarn polyester lycra.
