The temperatures must be hot enough to ensure that the yarns are adequately treated. 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. 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. Over the years, developments in air jet texturing have been related to the developments in nozzle design. It was built in 1969 as a result of vision of its founder Sh. 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 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. as the fibres will try to recover from the strain of being twisted. This page will explain how ATY is produced and where it is used. 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. A continuous filament yarn that has been processed to introduce durable crimps, coils, … 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? Fig.7 Illustration of the set-DTY process. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? 9. 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. Wraps per inch for each yarn weight is the number of times you can wrap the yarn around one inch of a ruler. Generally high-pressure steam is known to be cheaper to produce than compressed air. 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. Basically, the Filament? {dpf}, the most popular yarns being more towards 1dpf or finer. Rarely are yarns with a higher than 3.3dtex (3 denier) per Filament? If in the main drawing stage, the draw ratio is cyclically varied from high to low, while the Twist? So, air out side the tube with relatively higher pressure, rushes into the tube. The yarn is also constantly being twisted at the location X by some device, as its length moves through the distance AB. The figure shows the melt-spinning of nylon POY, which is then transferred to the draw texturing process. Both, S and Z means real twist in a yarn. Usually 18% to 30% overfeed may be applied, depending on end-use requirements; parallel yarns are commonly used cut pile plush fabrics. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp?

Air-jet texturing method. POY are preferred for air jet textured yarns largely because they are less expensive than FOY. 3. Fibres & Textiles in Eastern Europe, 17(3), 48-50. The speed of shaft 2 is always higher by the factor of the necessary draw ratio for the particular yarn and process. The heating element is essential for polyester POY, but nylon and polypropylene POY may be cold drawn. When POY is fed into the machine, the yarn has to be drawn. Inside, the tube yarn comes underFig. Hand, or … 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. One Heater DTY is normally woolly & more stretchable as compared to DTY with two Heaters. The heated yarn is passed between a pair of geared wheels or some similar device (gear crimping). 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 yarn is simultaneously twisted and drawn. FDY: Fully drawn yarn. The twisting is done with a friction device, such as a set of rotating … 6. The air-textured line manufactured by Sanathan Textiles is an excellent example that depicts how different yarns can be combined … Air-textured yarn (ATY) is an excellent substitute for the synthetic hand of false twist textured Yarn. Tel: 01484 346500 | Email: enquiries@textilehouse.co.uk, 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 color No is ZD7427 for polyester draw textured yarn and spandex covered yarn. 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. To describe the basics of the false Twist? winding tension produce yarn with higher phys. With this development yarns from finer denier to extremely coarse denier can be textured. McIntyre, J.E., and Daniels, P.N. by Marcel Dekker, 1998. Note that in the case of core effect type yarns, the two yarn paths must have their own drawing zone and therefore heating element. 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. 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. 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. Yarn preparation includes the addition of 3 - 4% wax emulsion after texturing to minimize plucking on beams. 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? Highly stretchable yarns can be made by applying high levels of false-Twist?, resulting in Twist? Keywords- False twist texturing, Draw … 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. The heated yarn is passed over a knife edge (edge crimping). 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. “Acelon Chemicals & Fibre Corporation”, http://www.allproducts.com/textile/acelon/12-split_micro_filament.html. Although CF yarns of virtually any polymer can be air-jet textured, the number of filaments and the dtex/denier per Filament? There is also pronounced effect of draw ratio and D/Y ratio shown on the textured yarn structure and properties. 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). 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 Fig.6  Illustrations of False-Twisting Devices. Draw textured yarn (DTY) and air-textured yarn are both made from partially oriented yarn (POY). 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. R. L; Pieters, R; and Morrison M. E; “Fundamentals of False-Twist? imparted by the texturing process. will be present as it leaves. What is the difference between S and Z twist: There is a little and a lot of difference. [13] Chuah, H. H. (2004). By including a mechanical drawing stage(i.e. The difference between colored spinning and dyed yarn Is the dyed yarn colored spinning? 4, … Simultaneously, the yarn length present within the zone XB will receive a counter clockwise torque, inserting S-Twist?. In zone XB, the S-Twist? Interlacing of filaments in the jet can cause the loops to be locked into the yarn so that any further twisting is unnecessary. The yarn is knitted into a fabric, heat-set and unravelled (knit-deknit). In air-jet texturing, filament yarns are fed over a tiny blast of air that forces the … 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. 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: … 10. 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]. With the clockwise spiral, the inclination of the helix mirrors the inclination in the letter Z, and the Twist? Yarns”, Journal of Rheology, 16, 3, 557-577, 1972. 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. are very important; a high number of filaments with a low detex/denier per Filament? Similar as in the tangling of yarns the center of the ATY becomes randomly braided. 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. 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. 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. inside the jet. The three-dimensional crimp is permanently set by the heat. Currently, the practice is to use between 1.1 and 2.2 detex (1 and 2 denier) per Filament? 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. 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. 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]. For more in-depth study of the principles of false-Twist? Where is the difference between ATY Yarn and DTY Yarn ? On the contrary, it is low elastic yarn. This means that within a short time of starting the twisting process, Z-Twist? texturing gives CF yarns a more natural feel bulk and stretch, their uniform geometry lacks the natural appearance of staple-spun yarns. Page 2 of 17 give greater bulk, higher stretch and more pleasing aesthetics. Moreover, increasing of OPP fraction in blend, reduce crim p properties of textured 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. All types of continuous filament yarns (PES, PA, PP, Glass, etc.) or dipping the yarn into a water bath; the water aids separation of the filaments and acts as a Lubricant? 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). usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? Find here online price details of companies selling Textured Yarn. 176 elongation at break, than on breaking force. There are small wool fibers with different lengths around the yarn. 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. Maker Filaments - Manufacturer & exporter of Fancy Air Textured Yarn. Draw Textured Yarn … Fig.3. Loops are formed in individual filaments by over-feeding into a turbulent airstream (air-textured… 9 Processes for Parallel and Core Effect ATY. 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. Hearle, J.W.S; Hollick, L;  and Wilson, D.K, “Yarn Texturing Technology”, Woodhead Publishing Ltd, Chapter 1, p.1-13, 2001, 8. The major apparel applications for draw-twist are in knitted garments, especially double jersey for women’s outerwear and woven fabrics. Kayavlon is exporting FDY yarns from India, China,Malaysia, Thailand DTY yarn can be in Semi Dull or Bright or Triloble … Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to . Brown, N.S; and Chuah,H.H, “Texturing of Textile Filament? Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. A ratio > 1, of input to output speed is termed the overfeed. The one device will therefore at any instant in time effectively Twist? There are basically 2 types of yarns which can be produced with air texturing. The elasticity can be obviously felt when pulling the two ends of the high elastic yarn. Yarns based on Poly(trimethylene trerephthalete)”, Chemical Fibres International, 47, 72-74, 1997. 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 Finishing Fabrics Containing Air Jet Textured Yarns Relaxation … 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. ATY Air Textured Yarn, similar to cotton in appearance. — Digital misty gray: PANTONE 13-4303TGP — In our factory, we can manufacture yarn with this color as well. being preferred. 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). and Spun Yarns”, Woven Cloth Construction, pub. The Filament? [1] There may be a slight loss of Twist? Loop size and loop stability are important factors, especially for finer detex/denier yarns. A spherical barrier is positioned close to the outlet orifice, so that as the compressed air exits it becomes a turbulent air flow. 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. Also known as dacron low spring silk, is the continuous or simultaneous stretching and deformation of finished products on a machine. It doesn't matter what size or width your ruler is as this metric measures the thickness of the yarn rather than the length. Dyed yarn: It is formed by dyeing the yarn through a dyeing process, which is first spinning and then dyeing. 6. The fabric woven with it has a cotton feeling. The new substitute product holds the potential for competitive advantage, lower manufacturing costs and streamlined manufacturing capabilities. Air textured yarn is very bulky with permanent crimps and loops. The usual setting temperatures are 230 - 240 °C for finer polyester 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. inserted; Twist? Polyester Fully Drawn Yarn is abbrevated as Polyester FDY. Reimschuessel, H;  Chapter 2 “Polyamide Fibres, p.144, in Handbook of Fibre Chemistry, Edited by Lewin, M; pub.

The Textile Institute, 1993. ; see. 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. Various techniques have been developed, therefore, to modify their appearance. 6 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? Molecular weight and molecular weight distribution currently limit PP-BCF yarns to 900dtex and 3000 m/min. If you would count the twist in both … Polyester (DTY) Drawn Textured Yarn yarn is obtained when Polyester POY is simultaneously twisted and drawn. 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. Since false-Twist? DTY: : Draw texturing yarn/ stretch textured 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. High elastic elongation is high elastic yarns. Warp Knitting Air Textured Yarns Fabrics have been satisfactorily knit. texturing requires the filaments to be initially heated above their Tg, the process is only suitable for thermoplastic polymeric  filaments. compaction resulting a false-Twist? It suggests that the increase of effect-yarn draw ratio increases the level of … in the clockwise direction, the yarn length present within the zone AX, inserting Z-Twist?. draw texturing is the most widely used method for converting flat thermoplastic CF yarns to ones of more bulky structures, air-jet texturing has become increasingly important because of  it capability to process CF yarns of any polymer type, not just thermoplastics, and also glass filaments. 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. The process used for achieving this staple-fibre like yarn is called “Texspun” developed by the machine manufacturer Barmag [75]. Should the yarn break, the twisted yarn on the left hand side also goes to waste. After the false twisting, the DTY passes through the additional heating zone to become a set-DTY. finishes and a yarn of 68trilobal filaments (2.44 dtex per filament) were textured. 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. Filament?-yarn.html">http://www.textileglossary.com/terms/Filament?-yarn.html    Jan2012, 5.       http://www.miniknittingstuff.com/yarn2.htm  Jan2012. In a very short time, the Z-Twist? loss increases with both factors. Dependences of air textured polypropylene yarn properties on the yarn structure and air pressure in a texturing jet. During the earlier years of false-Twist? 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? An example of the set-DTY process is illustrated by Fig.7. A vortex –jet design can also be used. The difference is that one yarn has been twisted into the opposite direction of the other yarn. texturing process it is necessary to first consider the meaning of real Twist? In this study yarns are produced with different level of air pressure i.e. The stuffer-box method is a fast and inexpensive method for carpeting yarn. contraction  at low applied force) depending on the level of false twisting. is referred to as S-Twist?

Get info of suppliers, manufacturers, exporters, traders of Textured Yarn for buying in India. What are the benefits of textured yarns? usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? To assist the loop formation, the filaments are wetted prior to entering the jet, by either Spraying? There are small wool fibers with different lengths around the yarn. Worsted is a hyponym of wool. 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. Subjecting the resulting yarn to washing or steaming results in the differential shrinkage of the filaments to form the ulked profile. 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 DP5-T DIGICONE® fastflex™ air texturing machine is designed for the flexible production of high quality air jet textured yarns. Other articles where Textured yarn is discussed: man-made fibre: Texturing: Texturing is the formation of crimp, loops, coils, or crinkles in filaments. 2. DTY yarn can be in Semi Dull or Bright or Triloble Bright … Core effect yarns are produced with two main components; core and the effect yarns. ester (DTY) Drawn Textured Yarn (DTY)Polyester DTY is obtained when Polyester POY is simultaneously twisted and drawn. When the POY is drawn and Twisted at the same time, the end product obtained is a draw textured yarn. In … What's the difference between DTY and FDY ? yarns find applications in a wide range of technical end uses. The rotation of the pin is effected by a driven disc assembly. 5. textured yarn; bulky with considerable stretch (elongation or Twist? Fig. Effect of process variables on bulk Free listing for companies. 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. 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. Mar 21, 2018. Of the above methods briefly described, the more widely used are false-Twist? We have strong network in China, Taiwan, South Korea, Malaysia, Thailand, Indonesia, Mexico, Spain, Italy & various other countries for Nylon DTY.Nylon POY is used for manufacturing … When the process is started the twisted yarn on the right side is discarded to waste. texturing and air-jet texturing, the former being the dominant. and the term false Twist?, and how the latter is produced. 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 . 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 fabric woven with it has a cotton feeling. 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. These entangle as the filaments get pulled together by removal rollers, to deliver an air- textured CF yarn. Although some of these features may be removed during downstream processing, sufficient are retained to give an enhanced textured appearance in the subsequent woven or knitted fabric. Another type of friction twisting device used is based on driven cross-belts. 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. ATY Air Textured Yarn, similar to cotton in appearance. Robinson, A.T.C and Marks, R.,  Chapter 1, p1, “Yarns and Their Characteristics: Continuous-Filament? Yarns should be textured with minimum overfeed to also minimize plucking. Polyester Textured Filament Yarn (PTY) can be draw textured or air textured yarn. What is the difference between S and Z twist: There is a little and a lot of difference. Abhay Jain. As Fig 6 illustrates, the pin twister is a hollow spindle with a central pin positioned across the tubular interior. The individual filaments are compacted by the air … However, air-textured yarn (ATY) has millions of small loops that offer a distinct look and feel. The drawing in my stretch yarn pageshows a running yarn in a false twisting machine. It offers a fresh new … DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments, home decorations, seat … In Fig32, the drawing zones for both yarn types have a heating element, which may be a heated pin, godet or plate. This study is related to production and testing of air covered yarn from polyester and lycra on air covering machine. will remain in the yarn, since the Z-Twist? What is Fully Oriented Yarn (FOY)? What is Fully Oriented Yarn (FOY)? Air texturing of a yarn is one of the most versatile methods of yarn texturing as it can combine type of filament Yarn together. This is the false-twisting action as Fig 4 illustrates. 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. However, where it is required that DTYs have relatively low 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 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 temperatures must be hot enough to ensure that the yarns are adequately treated. 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. 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. Over the years, developments in air jet texturing have been related to the developments in nozzle design. It was built in 1969 as a result of vision of its founder Sh. 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 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. as the fibres will try to recover from the strain of being twisted. This page will explain how ATY is produced and where it is used. 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. A continuous filament yarn that has been processed to introduce durable crimps, coils, … 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? Fig.7 Illustration of the set-DTY process. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? 9. 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. Wraps per inch for each yarn weight is the number of times you can wrap the yarn around one inch of a ruler. Generally high-pressure steam is known to be cheaper to produce than compressed air. 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. Basically, the Filament? {dpf}, the most popular yarns being more towards 1dpf or finer. Rarely are yarns with a higher than 3.3dtex (3 denier) per Filament? If in the main drawing stage, the draw ratio is cyclically varied from high to low, while the Twist? So, air out side the tube with relatively higher pressure, rushes into the tube. The yarn is also constantly being twisted at the location X by some device, as its length moves through the distance AB. The figure shows the melt-spinning of nylon POY, which is then transferred to the draw texturing process. Both, S and Z means real twist in a yarn. Usually 18% to 30% overfeed may be applied, depending on end-use requirements; parallel yarns are commonly used cut pile plush fabrics. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp?
