Problems solved by technology

But knitted elastic clothing has its own limitations again: one, also because it is weft knitting, plus elasticity, once broken yarn occurs, its clothing is much more damaged than traditional inelastic knitted clothing (whether it is weaving, etc.) processing or later wearing); 2. The knitting method makes the style of its clothing fixed and simplified; 3. The flat knitting machine requires manpower whether it is manual or semi-automatic, and the labor force rate is high, which increases the cost; 4. After adding elasticity to knitted clothing, it is almost completely close to the body, that is to say, this kind of clothing gives people a sense of restraint, not airy, not hanging, and not fashionable

Abstract

The invention relates to the technical field of stretch fabrics, in particular to a dyeing and finishing process for N-400 high-stretch nylon fabric, comprising the steps of joining, desizing, dyeing, dewatering, scotching, drying, and finalizing, wherein the desizing step is splitting type desizing process, and a moist heat tank, a desizing tank, three washing tanks and 36 rollers are preset, wherein a large meshed cylinder is mounted in each washing tank and is provided with a spray orifice water pipe.

Description

technical field [0001] The invention relates to the technical field of elastic fabrics, in particular to a dyeing and finishing process of N-400 high-elastic nylon fabric. Background technique [0002] With the continuous openness and innovation of the society, the diversified design styles of fabrics and the high-level life vision of consumers, when purchasing fabrics, they are more inclined to choose products that feel softer, more comfortable, elegant and rich, and more functional. Cloths currently on the market introduce elastic elements to meet the requirements of comfortable wearing. The currently popular elastic fabrics can be roughly divided into two categories from the raw materials: one, fabrics containing spandex; two, T-400 fabrics. These two types of fabrics have a common feature, they are all blended yarns, or covered, or sheath core, or twisted - all are a mix of at least two kinds of yarns, which results in more or less certain question. For example: Spand...
