Problems solved by technology

However, the length of yak wool fiber is short and the difference is large, the curl of the fiber is less and the curl shape is irregular, the specific resistance is high, it is easy to generate static electricity, the scales are ring-shaped, and the thickness is mixed. , the products are mainly knitting yak wool, yak wool sweaters, trousers, yak wool coats, etc., with low added value, and there have been no reports of pure spinning combed yak wool strips produced by wool-type technology at home and abroad.

Embodiment 1

[0010] Raw material: 100% white yak cashmere, velvet weight 20g / m.

[0011] Technological process: (1) Raw material pretreatment: Due to the large difference in thickness of yak velvet fibers and many different-colored hairs, to carry out worsted spinning, the yak velvet fibers should first be sorted, foreign fibers removed, velvet washed, and decolorized. Treatment, and then pre-carding on a carding machine, so that the fineness of the wool fiber is controlled at 17.5-20 μm, the fiber length is 17.5-20 mm, and the coarse hair is less than 0.2%.

[0012] (2) Wool blending: On the blending machine, spray blended hair oil and antistatic agent layer by layer on the yak down fiber, and control the moisture regain, and leave it for 8-12 hours; where: the added weight of blended hair oil is yak down fiber 0.4% of the total weight, the added weight of the antistatic agent is 0.5% of the total weight of the yak wool fiber, and the moisture regain is controlled at 21%.

Abstract

The invention discloses a production process of pure-spined combed yak wool. The production process includes steps of (1), raw material pretreatment including precombing on an opening machine and controlling the wool fiber fineness within 17.5-20 micrometers and the fiber length within 17.5-20 millimeters; (2), blending on a blending machine, spraying wool oil and antistatic agents on yak wool fibers layer by layer and controlling the moisture regain; (3), carding on a wool type carding machine according to the process principle of soft carding; (4), gilling on a two-stage gilling machine to realize pre-gilling; (5), combing by a wool type combing machine according to a small-space, light-quantitive and low-speed process; and (6), gilling and balling by two gilling steps. The production process has the advantages that pure-spined combed yak wool can be produced by the production process and can be prepared for the next process of spinning pure yak wool high-count combed yarns, and accordingly a gap in production of high-grade combed yak wool fibers is filled.

Description

technical field [0001] The invention relates to the technical field of animal fiber spinning, in particular to a slitting production process of pure spinning combed yak cashmere. Background technique [0002] Yak cashmere is almost a unique textile raw material in China. It has the characteristics of smooth and waxy hand feeling, good elasticity, good moisture absorption and release performance, wear resistance and pilling resistance, and high fiber strength. It even exceeds the wearing performance of cashmere, and is suitable for high-grade worsted clothing fabrics. However, the length of yak wool fiber is short and the difference is large, the curl of the fiber is less and the curl shape is irregular, the specific resistance is high, it is easy to generate static electricity, the scales are ring-shaped, and the thickness is mixed. , the products are mainly knitting yak wool, yak wool sweaters, trousers, yak wool coats, etc., with low added value, and there have been no re...
