Embodiment 1

[0027] The dyeing process of effectively improving elastic cloth white spots described in this embodiment comprises the following steps:

[0028] (1) Cloth splicing: Sew multiple stretch fabrics to be dyed together and send them to the desizing place for desizing, and control the transmission speed to 60-61m / min;

[0029] (2) desizing: take the mixed slurry containing sodium hydroxide, high-efficiency degreaser and refining agent as the first desizing liquid, control the concentration of the sodium hydroxide to be 40g / L, and the high-efficiency degreaser (high concentration The concentration of the chemical fiber degreasing agent G00N206A) is 3g / L, the concentration of the refining agent (refining agent TF-188) is 4g / L, the desizing temperature is controlled at 93°C, the desizing machine is desizing, and the washing temperature is controlled at 80°C , after the operation is OK, send it to the dyeing vat for standby;

[0030] (3) desizing in the cylinder: take the mixed slurry...

Embodiment 2

[0039] The dyeing process of effectively improving elastic cloth white spots described in this embodiment comprises the following steps:

[0040] (1) Cloth splicing: Sew multiple stretch fabrics to be dyed together and send them to the desizing place for desizing, and control the transmission speed to 60-61m / min;

[0041] (2) desizing: take the mixed slurry containing sodium hydroxide, high-efficiency degreaser and refining agent as the first desizing liquid, control the concentration of the sodium hydroxide to be 41g / L, and the high-efficiency degreaser (high concentration The concentration of the chemical fiber degreasing agent G00N206A) is 2g / L, the concentration of the refining agent (refining agent TF-188) is 5g / L, the desizing temperature is controlled at 95°C, the desizing machine is desizing, and the washing temperature is controlled at 85°C , after the operation is OK, send it to the dyeing vat for standby;

[0042] (3) In-cylinder desizing: take the mixed slurry con...

Abstract

The invention relates to the technical field of textile dyeing, in particular to a dyeing process for effectively improving elastic cloth white spots. The invention provides a dyeing process for effectively improving the white spots of elastic cloth. On the basis of the conventional dyeing process, after the basic desizing step, the in-cylinder desizing process is performed again. In the desizing step and the cylinder In the internal desizing step, a desizing solution with a specific composition and content is used, which effectively improves the phenomenon of silicone oil demulsification and back staining, greatly avoids the problem of easy formation of white spots during dyeing, and improves the success rate of the elastic fabric dyeing process from less than 30%. Increased to more than 95%, greatly improving production efficiency and effectively reducing production costs.

Description

technical field [0001] The invention relates to the technical field of textile dyeing, in particular to a dyeing process for effectively improving elastic cloth white spots. Background technique [0002] Elastic cloth (Elastic cloth), as the name implies, is an elastic gray cloth, that is, the ribbed texture makes the gray cloth have greater elasticity. Stretch cloth is often used as the inner layer of handbags and wallets, and it can also be used for the collar and cuffs of T-shirts, so that it has a better body tightening effect. [0003] With the continuous development of the textile and clothing industry towards fashion, the requirements for the dyeing process of various textiles are also getting higher and higher. At present, the dyeing of elastic cloth is mainly carried out by the general dyeing process. However, it is usually necessary to wash water before setting during the dyeing process. This is mainly because the general elastic cloth will contain a certain amou...
