Embodiment 1

[0026] The dyeing process that effectively improves the color blue dyeing stability described in the present embodiment comprises the following steps:

[0027] (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;

[0028] (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;

[0029] (3) Reservation: In order to avoid un...

Abstract

The invention relates to the technical field of textile dyeing, in particular to a dyeing process for effectively improving the dyeing stability of indigo. The invention provides a dyeing process that can effectively improve the stability of indigo dyeing. On the basis of the conventional dyeing process, through the carefully screened dyeing slurry, each component cooperates to play a role, effectively improving the silicone oil demulsification and back staining. phenomenon, which greatly avoids the problem of "dirty color" during dyeing, and increases the success rate of fabric color blue dyeing process from less than 30% 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 the dyeing stability of indigo. Background technique [0002] 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. The dyeing of clothes or cloth is an important processing procedure in the field of weaving and clothing, and is of great significance to the development of the clothing industry. [0003] At present, the dyeing of general fabrics usually needs to be washed before the dyeing process. This is mainly because the general fabric will contain a certain amount of silicon lubricating oil. Cross-linking will occur, it will be adsorbed on the fabric, and it will seriously hinder the dyeing of acidic materials during dyeing, thus forming dyed flowers, which is commonly referred to as "color dirty". ...
