Mar 21, 2018. winding tension produce yarn with higher phys. 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 drawing in my stretch yarn pageshows a running yarn in a false twisting machine. The decrease of loop density in the case of air-jet textured yarns may be due to smaller loops. Polyester Draw Textured Yarn (DTY) is a continuous filament yarn textured by heat setting in a twisted condition to . Reimschuessel, H;  Chapter 2 “Polyamide Fibres, p.144, in Handbook of Fibre Chemistry, Edited by Lewin, M; pub. Various techniques have been developed, therefore, to modify their appearance. See Fig.6. 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 … Interlacing of filaments in the jet can cause the loops to be locked into the yarn so that any further twisting is unnecessary. 'Textured Yarn' definition with manufacturers. What are the benefits of textured yarns? Free listing for companies. The Textile Institute, 1993. A third pair of rollers would then be used as the output rollers. This is the false-twisting action as Fig 4 illustrates. What is the difference between S and Z twist: There is a little and a lot of difference. Robinson, A.T.C and Marks, R.,  Chapter 1, p1, “Yarns and Their Characteristics: Continuous-Filament? finishes and a yarn of 68trilobal filaments (2.44 dtex per filament) were textured. 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 may be comprised of one or more POY. After spinning and drawing, a slight intermingling is given to the flat yarn to facilitate the easy post spinning processes[2]. The difference is that one yarn has been twisted into the opposite direction of the other yarn. 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 … — Digital misty gray: PANTONE 13-4303TGP — In our factory, we can manufacture yarn with this color as well. The heated yarn is passed between a pair of geared wheels or some similar device (gear crimping). To describe the basics of the false Twist? loss increases with both factors. An example of this method is the taslam process; Air jet textured yarn. Fig. Viewed from B, along the length BX, it will appear to turning counter clockwise. or dipping the yarn into a water bath; the water aids separation of the filaments and acts as a Lubricant? texturing FDY/FOY yarns were texturised using a rotating pin as the false-Twist? insertion is similarly varied, the textured yarn will have thick and thin places along its length. Rarely are yarns with a higher than 3.3dtex (3 denier) per Filament? This study is related to production and testing of air covered yarn from polyester and lycra on air covering machine. Drawn Textured Yarn (DTY) yarn is obtained when Polyester POY is simultaneously twisted & drawn. The speed of shaft 2 is always higher by the factor of the necessary draw ratio for the particular yarn and process. 9.

Polyester Fully Drawn Yarn is abbrevated as Polyester FDY. ATY Air Textured Yarn, similar to cotton in appearance. Dependences of air textured polypropylene yarn properties on the yarn structure and air pressure in a texturing jet. 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. On the contrary, it is low elastic yarn. In this device the compressed air has a spiralling turbulent flow to the outlet, the loose Filament? Other articles where Textured yarn is discussed: man-made fibre: Texturing: Texturing is the formation of crimp, loops, coils, or crinkles in filaments. Simultaneously, the yarn length present within the zone XB will receive a counter clockwise torque, inserting S-Twist?. DTY yarn can be in Semi Dull or Bright or Triloble … The DP5-T DIGICONE® fastflex™ air texturing machine is designed for the flexible production of high quality air jet textured yarns. Figure 3: Application of Intermingling While Spinning. imparted by the texturing process. DTY Elastic Yarn can be divided into high elastic yarn and low elastic yarn. See Fig 9. The fabric woven with it has a cotton feeling. The difference is that one yarn has been twisted into the opposite direction of the other 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). After the false twisting, the DTY passes through the additional heating zone to become a set-DTY. Yarns should be textured with minimum overfeed to also minimize plucking. In air-jet texturing, filament yarns are fed over a tiny blast of air that forces the … 6. So, air out side the tube with relatively higher pressure, rushes into the tube. Fig.3. View full-text Article Loop frequency, loop dimensions, loop stability and physical bulk are the important characteristics of air textured yarns.
