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.

Embodiment 1

[0028] First select 55 parts by weight of flax raw material and 45 parts by weight of tencel, divide the linen into pounds, and then go through the big cut, the first round comb, the middle cut, the second round comb, the small cut, and the third time. The linen sliver is made by arranging hemp and spreading the element comb; the tencel sliver is incorporated into the linen sliver to make sliver, and the blended roving is made by drawing five times, and the roving is passed through Scouring to obtain spun yarn, and then drying, winding, and packaging into the required blended yarn.

[0029] The cooking and smelting includes the following steps:

[0030] (1) Pickling: under normal pressure at a temperature of 30°C, processing is carried out in a 10,000 kg aqueous solution containing 15 kg of concentrated sulfuric acid (98% sulfuric acid solution) and 5 kg of penetrant, and the treatment time is 20 minutes.

[0031] (2) Sub-bleaching: under normal pressure at a temperature of 30°C, ...

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...
