Tencel Fiber Spinning Technology And Spinning Method

Tencel is a regenerated cellulose fibre that made from natural woods.Its process of production is clean and nonpoisonous. 99.5 percent of solvent can be retrieved, very little of the left sediment can be cut down and decomposed through the suitable biological degradative process. So it has good environmental protective property.Tencel is a high-tenacity fibre. Whenever it in dry or wet condition, it has high strength. In dry condition, high strength means the fabric has good shape relenlion, it can improve spinning and weaving production efficiency. In wet condition, high strength can keep fabric's shape stableness in production or in cleaning process. Its good hygroscopicity make it has fine substantivity, thus it can reduce the production costs in printing and dyeing mill. Tencel has good spinnability, it can blend spinning with cotton, linen, wool, silk, cachmire, polyester etc variousnt fibres, and spin various different counts of yarn. Tencel fabric is wear-comfort, softness, good breathability, great touch, and easy wash and wear. It is the first selection of wearing apparel and home textiles especially pajamas and bed clothes. So our company pay more attentions to produce and develop series new varieties.Through Tencel spinning production practice in scotching, carding, drawing, roving, spinning and winding process, we set up rational spinning process to control quality, further improve semi-manufactured goods and yarn property to good level. After all we select optimun process parameter through orthogonal design in roving to further control yarn property. On the other hand, we combine the substand and products in the process, through wavegram analysis to find reasons of the failure, finally we accumulate some experience by the effective quality control.We draw into a new spinning technology-Sirospun for further improve Tencel yarn quality. The Sirospun is a new technology of woolen spinning, which combine spinning, doubling and twisting into one operation. The Sirospun yarns and its products have special styles, good markets and high economical benefits, so the Sirospun has been well favored by textile factories because its low expenses in equipmentmodification and high extra-value of the products. The Sirospun principle, technological requirements, peocessing equipment, product specialties and processing program are described here in detail. It has important practical significance in spreading Sirospun technology in china-made spinners, and compare sirospun yarn property to ring spinning yarn property, showing sirospun yarn has very good property. Especially the Sirospun technology has been applied to produce core yarn. It can make yarn has good wraping effection, yarn touch softness, good wear-resisting, good yarn evenness, and strength is better than traditional core yarn.As a new process, through spinning in the transformed traditional ring spinning, it not only improves yarn quality but also fits to the demands of high speed of air-jet loom in the next process, and can reduce production costs, improve production additional value, so it has dood market progress prospect.
