Embodiment 1

[0046] Embodiment 1: a kind of dyeing and finishing process of cotton and T400 interweaving elastic fabric, it is characterized in that: comprise the following steps:

[0047] (1) Singeing: One burner is positive and the other is reversed, the flame temperature is 900°C, the singeing air pressure is 12mbar, and the vehicle speed is 110m / min;

[0048] (2) The first open-width desizing: transport the singeed fabric to the open-width desizing machine, the temperature of the open-width desizing is 80°C, the time is 30min, and the moving speed of the fabric is 60m / min; Steam at 100°C for 1 hour, then fully wash with hot water and cold water successively, then paddle with 5g / L sulfuric acid solution, then stack for about 1 hour, and then fully wash with water;

[0049] The open-width desizing liquid used is composed of the following components by weight: 4 parts of liquid caustic soda with a concentration of 32%, 3 parts of hydrogen peroxide with a concentration of 35%, 2 parts of f...

Abstract

The invention discloses a dyeing and finishing process for cotton and T400 interweaved elastic fabric and relates to the technical field of elastic fabric dyeing and finishing. The key point of the technical scheme is that the dyeing and finishing process comprises the following steps: (1) singeing; (2) performing first open-width desizing; (3) performing secondary open-width desizing; (4) dyeing:putting a fabric into a high-temperature high-pressure liquid dyeing machine and then adding 20-30 parts of dyestuff and 30-50 parts of auxiliaries at 45 DEG C, wherein the auxiliaries include 20-30parts of superfine fiber leveling agent, 10-20 parts of 12-60g / L anhydrous sodium sulphate and 120-150 parts of 50% glacial acetic acid; (5) sizing. According to the invention, the problem of low dyeing percentage and dyeing uniformity of the cotton and T400 interweaved elastic fabric can be solved. Specifically, the dyestuff can be uniformly dipped on the fabric and the dyeing percentage and thedyeing uniformity can be increased, in the manner of accurately controlling the dyeing temperature and heat preservation time.

Description

technical field [0001] The invention relates to the technical field of elastic fabric dyeing and finishing, more specifically, it relates to a dyeing and finishing process of cotton and T400 interwoven elastic fabric. Background technique [0002] Ordinary cotton fabric is natural and rustic, comfortable to wear, but lacks elasticity, is easy to wrinkle, and has poor shape retention. T400 fiber is a new type of composite polyester fiber, which is composed of two different polyester fibers side by side and compositely spun. Due to the different shrinkage rates of the two polyester fibers, the fiber can produce permanent three-dimensional curls, so that the fiber It has excellent elasticity. Introduce T400 fiber into ordinary cotton fabric, use cotton yarn as warp yarn, T400 fiber as weft yarn, and interweave cotton and T400 interwoven elastic fabric, which can endow the fabric with excellent elasticity and dimensional stability, and at the same time have strong memory functi...
