Abstract

The invention provides a Sorona fiber-containing fabric and a dyeing and finishing process and application thereof, and the dyeing and finishing process comprises the following steps: (1) mixing a raw material fabric, a softening agent and water, heating, preserving heat, and cooling to obtain a boiled and shrunk fabric; (2) carrying out heat setting on the boiled and shrunk fabric obtained in the step (1) to obtain a heat-set fabric; and (3) dyeing the heat-set fabric obtained in the step (2), and performing post-shaping to obtain the fabric. The dyeing and finishing process provided by the invention can effectively eliminate wrinkles of the fabric containing Sorona fibers, so that the finished product has the characteristic of no cloth wrinkles.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a fabric containing Sorona fibers and a dyeing and finishing process and application thereof, in particular to a wrinkle-free fabric containing Sorona fibers and a dyeing and finishing process and applications thereof. Background technique [0002] Sorona fabric is an elastic fiber with similar feel and water absorption speed to cotton fabrics. It has soft hand feel, long-lasting shape retention, good moisture absorption and perspiration performance, comfortable wearing, good wrinkle resistance, and comfortable elasticity with polyester / cotton blended fabrics. Advantages are a major trend in the development of textile fabrics in the future. However, at present, mass production generally adopts the process of first heat setting and then dyeing the finished product. Sorona and polyester / cotton blended fabrics are prone to wrinkle problems when this process is used, which serious...
