Embodiment 1

[0028] The preparation method of low shrinkage elastic belt comprises the steps:

[0029] S1. Weaving: Among them, the yarn adopts nylon / spandex covered yarn method, twisted to 600 twists first, and then untwisted to 500 twists, and the twist direction is Z twist.

[0030] S2. Retraction: Natural retraction is adopted, the temperature is 26°C, and the air humidity is 20%. Natural retraction 24h.

[0031] S3. Drying: drying the naturally retracted elastic belt, the drying temperature is 70° C., and the drying time is 3 hours.

[0032] S4. Dyeing: dyeing the dried elastic band, immersing the dried elastic band in a dyeing tank to obtain the primary dyed elastic band, and finally washing with water to obtain the washed elastic band.

[0033] Among them, the dyeing tank includes the following components in terms of water volume: acid leveling agent ES 20g / L, acid penetrating agent FL10g / L, and is dyed at room temperature.

[0034] And during water washing, described first-dyed ...

Abstract

The invention discloses a preparation method of an elastic band with low shrinkage rate, and belongs to the technical field of elastic fabrics. The preparation method of the elastic band with the low shrinkage rate comprises the following steps of weaving, retracting, drying, dyeing, rolling, shaping and packaging. The prepared elastic band is low in shrinkage rate, high in color fastness and long in service life, and the opening degree of the elastic band can be maintained for a long time, and the effective elasticity of the elastic band can be maintained.

Description

technical field [0001] The invention belongs to the technical field of elastic fabrics, and in particular relates to a preparation method of an elastic belt with low shrinkage rate. Background technique [0002] With the development of society, there are countless textile products. Among them, elastic belts are widely used in clothing products such as trousers, socks, cuffs, etc., especially in underwear and underwear. [0003] The Chinese invention patent with application number 201710157787.6 discloses a low-shrinkage treatment method and finishing method for high-elastic fabrics. The steps include washing, dehydration, opening, drying, and pre-shrinking treatment. Although the high-elastic fabric produced by it has a low shrinkage rate of -5%, it still needs to include two pre-shrinking treatments in the preparation process, and the process is relatively complicated. [0004] Therefore, it is necessary to provide an elastic belt with low shrinkage rate, which is convenie...
