AI Technical Summary

Technical Problem

Existing technology cannot precisely control the weft skew and static shrinkage twist of worsted wool twill fabrics, affecting garment production and wearing effect.

Method used

The finishing process involves finishing, singeing, flat washing, boiling, first drying, steaming, washing, water absorption, double boiling, second drying, brushing and shearing, third drying, KD steaming, rolling and packaging, first pre-shrinking, balanced placement, second pre-shrinking, and finished product inspection. Weft skew and static shrinkage twist are controlled through precise settings.

Benefits of technology

It achieves a weft skewness of ≤3.0% and a static shrinkage twist of ≤2.5%, meeting relevant standards, improving the softness and luster of the fabric, and ensuring the quality of the fabric.

Abstract

This application relates to a finishing process for a worsted wool twill fabric, comprising the following steps: finishing, singeing, flat washing, scalding, first drying, steaming, washing, water absorption, double boiling, second drying, brushing and shearing, third drying, KD steaming, rolling and packaging, first pre-shrinking, balanced placement, second pre-shrinking, and finished product inspection; wherein, the fabric is washed with detergent at a temperature of 40~50℃; a reverse skew is adopted with a greater degree of skew than the actual skew, the degree of skew is twice that of the normal skew; the drying temperature is 120℃~130℃, and the overfeed rate is 8~20%; the washing includes a shrinking plate pressure of 0.2~0.4 bar, a washing liquid to fabric ratio of 1:300, a roller pressure of 0.8~1.0 bar on the fabric, addition of a shrinking agent, and the operating speed of the washing machine is 150~200m / min, with each 100 meters of fabric being washed and shrunk for 30 minutes. This application, through refined post-processing settings, can precisely control the weft skew and static shrinkage twist of the fabric.
