The first type is called parallel yarns and the second type core effect yarns, and Fig.9 illustrates the production of both. The air-textured line manufactured by Sanathan Textiles is an excellent example that depicts how different yarns can be combined … The flat CF yarn passes down the tube and around the pin. Air jet textured yarns are a spun look like alternative to the more synthetic hand of false twist textured yarns. The usual setting temperatures are 230 - 240 °C for finer polyester yarns. Therefore a variety of air-texturing jets are available to cover the different ranges of dpf. The difference is that one yarn has been twisted into the opposite direction of the other yarn. usually intended to be cut or stretch-broken for use in staple fibre or top form.">Tow?.">Crimp? This heating stage gives an additional heat-setting treatment which reduces the intrinsic Elasticity? 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. 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. What's the difference between DTY and FDY ? Vijay Kumar Yadav. Yarns should be textured with minimum overfeed to also minimize plucking. Bulk Continuous Filament? An example of this method is the taslam process; Air jet textured yarn. The stuffer-box method is a fast and inexpensive method for carpeting yarn. Molecular weight and molecular weight distribution currently limit PP-BCF yarns to 900dtex and 3000 m/min. contraction  at low applied force) depending on the level of false twisting. 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. 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. One Heater DTY is normally woolly & more stretchable as compared to DTY with two Heaters. An example of the set-DTY process is illustrated by Fig.7. 4.

The temperatures must be hot enough to ensure that the yarns are adequately treated. There are small wool fibers with different lengths around the yarn. High elastic … Moreover, increasing of OPP fraction in blend, reduce crim p properties of textured yarn. Spinning speeds between 3000 m/min to 4000m/min provides a partially oriented yarn which later requires draw of two during the draw texturizing. device. Simultaneously, the yarn length present within the zone XB will receive a counter clockwise torque, inserting S-Twist?. Subjecting the resulting yarn to washing or steaming results in the differential shrinkage of the filaments to form the ulked profile. There are basically 2 types of yarns which can be produced with air texturing. View full-text Article Physical properties of drawn yarns and textured yarns were reduced w ith increasing of OPP fraction. lengths in the turbulent flow initially become separated, forming a profusion of loops of various sizes. Textiles Terms & Definitions, Compiled by The Textile Institute Textile Terms and Definitions Committee, Ed. 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. Reimschuessel, H;  Chapter 2 “Polyamide Fibres, p.144, in Handbook of Fibre Chemistry, Edited by Lewin, M; pub. 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. 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.
