Don't worry - you won't be asked for your credit card info during the checkout process (unless, of course, you also have yarn in your cart). SUMMARY The Department of Commerce (Commerce) preliminarily determines that countervailable subsidies are being provided to producers and exporters of polyester textured yarn (yarn) from the People’s Republic of China (China), as provided in section 703(b)(1) of the Tariff Act of 1930, as amended (the Act). This test procedure has been designed for yarns up to 500 dtex. The yarn is prepared by bringing a running bundle of filaments in contact with two bending members for bending the thread-line so as to fix the thread-line between them and air jet interlacing the filaments as they pass between the bending members while forming such a stabilized thread-line. The process to produce textured yarns is known as bulk continuous filament (BCF) production. In the case of aged and then textured POY yarn, it seems that the percentage of crystallinity is almost equal to yarn without aging and textured at 190 C. POY is subjected to externally applied forces and internal stress during draw texturizing process. Textured yarns are synthetic continuous filaments, modified to impart special texture and appearance. About this page. Set alert. The individual filaments are tangled to produce staple-spun yarn like textures. A mechanical yarn break detector located below the drafting system continuously controls the yarn path of both single yarns throughout the spinning process. Air textured yarns will yield, when produced correctly, a wonderful spun like hand. Supervisory Investigator. All this would be meaningless if the process would not offer a splendid return on the investment. They are also used in the production of artificial fur, carpets, blankets, and drapery and upholstery fabrics. Why not give it a go yourself? In flat-filament yarns, each filament is almost perfectly straight, so that it lies flat and smooth in the yarn. The ratio of the disk surface speed to the yarn speed is usually referred to as /Y ratio. D/Y ratio is D calculated as follows: D/Y= min) min) throughput speed of yarn (m/ circumfere. Tag: High Speed Oriented Textured Yarn(HOY) PDF Report. U.S. International Trade Commission COMMISSIONERS David S. Johanson, Chairman Rhonda K. Schmidtlein Jason E. Kearns Randolph J. Stayin Amy A. Karpel Staff assigned Charlie Cummings, … The different warp and weft combinations have been prepared as shown in Table 3. 1.4.1 Processing of filament yarns. Filament yarns are either flat or textured. steam-jet textured yarns and tested for sewability of the threads to check the feasibility of this yarns for sewing thread applications. Free super bulky scarf pattern . It uses yarn hanks with an overall count of approx. 1.2 This test method applies to crimped, continuous multi- Þlament yarns ranging from 1.7 to 88.9 tex (15 to 800 denier). Production of textured yarn and method for containing said yarn . The heated yarn is passed between a pair of geared wheels or some similar device (gear crimping). – This sweater has a classic fit, with about 2”-3” (5-7.6 cm) of positive ease. The yarns are then heatset. For testing of textured yarns, the crimp con-traction test procedure according to German standard DIN 53 840 or the European standard EN 14 621 is nowadays finding worldwide applica-tion in industrial quality control as well as for R&D purposes. Polyester Textured Yarn from China and India Investigation Nos. In the production of abraded yarns, the surfaces are roughened or cut at various intervals and given added twist, producing a hairy effect. INTRODUCTION . This page will explain to you the principle on how yarns are interlaced, why yarns are interlaced and why interlacing has become such an important factor in the production of textured yarns.
