Abstract

The invention discloses a production method of elastic denim fabric with a low shrinkage rate. The method includes the specific steps of spinning, dyeing, sizing, weaving and after-finishing. The spinning process includes the procedures of blowing, carding, drawing, roving, spinning and spooling; the dyeing process includes the procedures of ball warping and bundle type dyeing. By means of the method, the weft shrinkage rate of the elastic fabric is reduced, the elastic property of the fabric is improved, and the effects of improving the wearability of pure cotton denim fabric and improving the wearing comfort are achieved; cotton / viscose blended warp is adopted for weaving the denim fabric, a reasonable spinning technology is adopted, and thus the blending uniformity is improved; through production technology optimization, the performance of the product is improved; an air loose softening finishing machine is adopted for loose softening finishing in the after-finishing stage, so that the weft shrinkage rate of the denim fabric is greatly reduced, and the elastic property of the denim fabric is improved.

Description

technical field [0001] The invention relates to the technical field of clothing fabrics, in particular to a production method of elastic denim fabrics with low shrinkage rate. Background technique [0002] With the continuous improvement of people's material living standards, the demand for high-end textiles in the market is increasing day by day. In the selection of raw materials, it has broken through the cotton-based pattern, and is developing from a single pure cotton product to blended, elastic and differentiated products. Denim clothing made of elastic denim has excellent elasticity and shape retention, and is deeply loved by consumers, especially young and middle-aged groups, so it has been popular and has been selling well. [0003] Usually along with the increase of elastic denim fabric elasticity, the washing shrinkage rate of fabric also will become larger, and this restricts the further development of elastic fabric. This requires us to formulate corresponding ...
