Producing technology of blended yarn of flax and tencel

Abstract

A blended yarn of flax and tencel, which is composed of the following two fibers by weight percentage: 50-60% of flax fiber and 40-50% of tencel fiber; its production process includes the following steps: (1). Flax is made into linen strips and mixed with tencel strips to make strips, and then drawn into rovings; (2), the rovings are boiled to make spun yarns; (3), the spun yarns are dried and entwined The barrel is made into blended yarn; wherein the scouring in step (2) includes the following steps carried out in sequence: pickling with sulfuric acid solution; sub-bleaching with a mixed solution of sodium chlorite and sodium nitrate; Washing; Oxygen bleaching with a mixed solution of sodium carbonate, sodium hydroxide, sodium silicate and hydrogen peroxide; second washing; this blended yarn combines the strengths of the two fibers and complements the shortcomings of a single fiber. The scouring process can Increase the spinnable count of flax fiber, improve the yarn forming effect, and make the produced mixed yarn have the advantages of moisture absorption, wrinkle resistance, coolness and good luster.

Description

Technical field [0001] The invention mainly relates to a spinning yarn and its production process, in particular to a blended yarn of flax and tencel and its production process. Background technique [0002] Flax cellulose has the reputation of "fiber queen". Its textiles have the characteristics of moisture absorption, fast heat dissipation, strong tension, good gloss, fast moisture dissipation, acid and alkali resistance, and rot resistance, but its disadvantages are poor spinnability and wrinkle resistance. . [0003] Tencel fiber is a brand-new fiber produced by solvent spinning method with wood pulp as raw material. It has the "comfortability" of cotton, the "strength" of polyester, the "luxury beauty" of wool fabrics, and the "unique touch" and "soft drape" of silk. It is extremely tough regardless of whether it is wet or dry. In the wet state, it is the first cellulose fiber with wet strength far better than cotton. 100% pure natural materials, coupled with environmentally...

Problems solved by technology

However, the elongation is small, the fiber cohesion is poor, and it is easy to break and fibrillate. If it is not handled properly, it will easily increase the content of short fibers and produce electrostatic slippery phenomenon, which will directly affect the evenness of the yarn.
