imparted by the texturing process. 4, â¦ 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 study suggests that shrink age difference in the feeder yarn is not an effective way to increase the bulk of air-jet textured yams. 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. Dyed yarn: It is formed by dyeing the yarn through a dyeing process, which is first spinning and then dyeing. Various techniques have been developed, therefore, to modify their appearance. Usually 18% to 30% overfeed may be applied, depending on end-use requirements; parallel yarns are commonly used cut pile plush fabrics. Polyester Drawn Textured Yarn (Polyester DTY) Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted and drawn. We will show you the difference between a parallel and a DTY yarn can be in Semi Dull or Bright or Triloble Bright … This is an assembly of overlapping discs which enables the CF yarn to be directly friction twisted, replacing the need for the hollow spindle. remains in the yarn. This type of application field is common to both flat and textured yarn. One or more ends of filament yarn are overfed at a constant rate to a special air jet, which blows, depending on the amount of overfeed between the inlet and outlet feeds, the yarns into a continuous string of smaller and larger loops. The DP5-T DIGICONE® fastflex™ air texturing machine is designed for the flexible production of high quality air jet textured 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. 6. Since the advent of synthetic filament yarns, the preceding difficulties have been faced by textile industry and naturally several solutions have also been applied to overcome. When Twist? Finishing Fabrics Containing Air Jet Textured Yarns Relaxation … 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 … View full-text Article Core effect yarns are produced with two main components; core and the effect yarns. 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. 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. This page will explain how ATY is produced and where it is used. 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,. 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. 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. will be seen in the yarn as it runs into the twisting device, but no Twist? 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). After the false twisting, the DTY passes through the additional heating zone to become a set-DTY. The color No is ZD7427 for polyester draw textured yarn and spandex covered yarn. Of the above methods briefly described, the more widely used are false-Twist? It was observed that Demir’s method is a practical and reliable way to compare the instability of air-jet textured yarns produced from the same raw material. Air jet textured yarns are a spun look like alternative to the more synthetic hand of false twist textured yarns. Both, S and Z means real twist in a yarn. A ratio > 1, of input to output speed is termed the overfeed.
