Problems solved by technology

The commonly used method to improve the fabric style of high-grade knitted cotton fabrics on the market is to add biological enzyme washing between the scouring and bleaching process and dyeing of the fabric after weaving, so as to reduce the surface hairiness of the fabric through biological enzyme washing, and at the same time improve the elastic recovery performance of the fabric. , but the strength and dimensional stability of the fabric will decrease accordingly due to the reduction of the stress between fiber molecules after cellulase treatment

Abstract

The invention relates to a method for processing water soft cotton knitted fabric, which comprises the following steps of: preparation of grey yarns, enzyme washing of the grey yarns, weaving, boiling, dyeing, dehydration, drying, super-soft treatment, sizing and preshrinking. In the method, after the yarns are subjected to enzyme treatment, the fibers become porous and loose so that the yarns become soft and fluffy and the dyeing rate is improved, and fluffs on the surfaces of the yarns are removed so as to achieve the effects on surface finish and piling resistance and improve the drapability, softness and water absorbability of the fabric; and by combining the post super-soft treatment, polyurethane in finishing liquor can easily permeate into the yarns and produce cross-linking reaction with fiber molecules and other aid groups to form a three-dimensional netlike structure so as to endow the fabric with the characteristics of durable elasticity and dimensional stability and 'watersoft cotton' softness like water. The final finished fabric produced by the method has the advantages of soft and exquisite handfeel, strong gloss sense, surface finish and good resilience.

Description

Technical field [0001] The invention relates to a processing method of a cotton knitted fabric, in particular to a processing method of a water soft cotton knitted fabric. Background technique [0002] Knitted fabrics are widely used in formal wear, casual sportswear, underwear, etc. because of their softness, comfort, good elasticity, and variable structure. At present, domestic and foreign manufacturers and colleges have conducted a lot of research on the high-grade of knitted fabrics. It mainly involves the style, function and stability of the fabric, and the main research content of the style of the fabric focuses on the hand feeling, elastic recovery performance and luster of the knitted fabric. [0003] The conventional fabric production process is as follows: raw yarn preparation → weaving → boiling and bleaching → dyeing → dehydration → drying → shaping → pre-shrinking. The methods commonly used to improve the fabric style of high-grade knitted cotton fabrics currently on ...
