Problems solved by technology

[0004] At present, the existing nylon fiber will cause the fabric to feel hard after a series of dyeing and finishing processes, which reduces the comfort when wearing.
[0005] At the same time, in the dyeing and finishing process of existing nylon fabrics, due to the unreasonable setting of drying temperature and finishing temperature, the width of nylon elastic fabrics after finishing under its own elasticity changes greatly, and the width of the entire fabric is unstable. There are problems such as "the width is wide and the time is narrow", which seriously affects the elasticity of nylon fabrics

Abstract

The invention discloses a dyeing and finishing process of an elastic soft chinlon fabric and belongs to the technical field of fabric dyeing and finishing. The dyeing and finishing process of the elastic soft chinlon fabric comprises the following steps of feeding the elastic chinlon fabric in hot water for desizing, then conducting presetting, immersing the elastic chinlon fabric into hot water of 30-40 DEG C, adding a refining degreasing agent and a penetrating agent, conducting heating and then heat preservation for 10-20 min, conducting water washing and cooling, feeding the elastic chinlon fabric into an overflow dyeing machine, adding dye and an acid leveling agent for dyeing, feeding the elastic chinlon fabric in a soaping agent for soaping for 15-20 min, feeding the elastic chinlonfabric in a color fixation solution for color fixation, conducting soft finishing and drying, feeding the elastic chinlon fabric in a heat-setting machine for heat setting to enable the setting to be2-3 cm wider than that of a finished product. The dyeing and finishing process of the elastic soft chinlon fabric is good in color fixation performance and capable of effectively maintaining the elasticity of the fabric and effectively improving the sweat absorption and moisture discharge performance.

Description

technical field [0001] The invention belongs to the technical field of elastic fabrics, in particular to a dyeing and finishing process for elastic soft nylon fabrics. Background technique [0002] Nylon is a polycondensate produced from organic diamine and diacid lactam. It contains phthaloamide group (-CONH) in its molecular structure, so it has many excellent physical, chemical and mechanical properties, including high strength, Good solidity, strong wear resistance, good thermal stability and other excellent characteristics. [0003] In recent years, people's requirements for the comfort, health, safety and environmental protection of clothing fabrics have been increasing. Among them, moisture-absorbing and sweat-wicking functional fabrics are favored by consumers because of their high comfort. Aquator nylon fiber is a new type of fiber with moisture absorption and perspiration function newly developed in the international market. It has a large specific surface area, ...
