Production process of yak hair/wool blended yarn woven fabric

Abstract

The invention discloses a production process of yak hair / wool blended yarn woven fabric. The production process comprises the steps of woven fabric preparation, repairing, body inspection, bag sewing,washing shrinkage, wet inspection, drying, middle inspection, cooked repair, decatizing, card wire raising, teasel raising, shaping, drying, shearing, lustring, shearing, finished product obtaining and packaging. A production process of yak hair / wool blended yarns comprises the steps of wool mixing, carding, spinning, spooling and two-for-one twisting, wherein the ratio of yak hair to wool is 60to 40 or 70 to 30. According to the production process of the yak hair / wool blended yarn woven fabric, through tests and blending of a specific proportion, the yak hair and the wool are blended to obtain the blended yarns, and the prepared blended yarns meet the index requirements of wool spinning at the official moisture regain, the weight unevenness, the twist irregularity and the twist difference rate; and through a specific post-treatment process, the yak hair with low value and low utilization rate is converted into the high-quality yak hair roved woven fabric.

Description

technical field [0001] The invention relates to the field of commercialization of special animal fibers. A low-utilization yak hair with large diameter, short length and poor strength is blended with wool according to the test ratio, and a stable yak wool blend is obtained by improving the production process. Yarn, and then through a specific post-processing process, to obtain a unique style of woolen yak wool woven fabric. Background technique [0002] Yarn spinning of wool and cashmere is relatively mature in the prior art, and yak cashmere products are also emerging in the market in recent years. The yak is a unique breed of cattle on the alpine grassland. It grows in the alpine region above 3,000 meters above sea level. It has rich and long coats all over its body, and has downy hair on its body. Because of the climate characteristics of living in plateaus and altitudes all year round, the downy hair of yaks Provides warmth with great style. [0003] In recent years, s...
