Abstract

The invention discloses a production method of elastic denim fabric with low shrinkage rate. The specific steps include spinning, dyeing, sizing, weaving and post-finishing; Process, spinning process, winding process; the dyeing process includes the ball warping process and the bundle dyeing process. The invention reduces the weft shrinkage rate of the elastic fabric, improves the elastic performance of the fabric, improves the wearing performance of the pure cotton denim fabric, and improves the effect of wearing comfort. , Improve the uniformity of blending, and improve the performance of the product through the optimization of the production process. In the post-finishing stage, the air loose soft finishing machine is used for loose soft finishing, which greatly reduces the weft shrinkage of the denim fabric and improves the denim fabric. elastic properties.

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 ...
