Problems solved by technology

[0003] Existing problems: the weft yarn is thinner, the cohesion is poor, and the weft yarn is easy to loose during the weft insertion process, and the spandex shrinks
The thicker the spandex, the greater the elasticity and the greater the shrinkage, and it is very easy to produce weaving defects such as loose weft yarns, which cannot be improved by repairing the fabric

Abstract

The invention discloses a dyeing and finishing process of an outdoor multifunctional high-count high-density cotton-nylon elastic yarn-dyed fabric. The dyeing and finishing process sequentially comprises a tube loosening process, a dyeing process, a sizing process, a weaving process and an after-finishing process, and the after-finishing process sequentially comprises a desizing process, a high-temperature setting process, a setting and feeding process and a pre-shrinking process. The problems that in the prior art, weft yarn is thin, cohesive force is poor, and silk loosening is likely to happen and spandex is likely to retract in the weft insertion process are solved.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a dyeing and finishing process of an outdoor multifunctional high-count and high-density cotton-nylon elastic yarn-dyed fabric. Background technique [0002] High-count and high-density fabrics have the characteristics of fine and soft hand feeling, smooth and silky, and are a development direction for further processing in the textile industry and increasing the added value of products. Due to the characteristics of fine yarn count and large fabric density, high-count and high-density varieties have high stoppage of looms and low weaving efficiency, especially after dyeing high-count and high-density yarn-dyed yarn, its single yarn strength, elongation, hairiness and other indicators are higher than original ones. The yarn index is worse and the production is more difficult. Weft filament stretch fabric has excellent elastic recovery rate, machine washable, ...
