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...

Abstract

The invention relates to the technical field of textile dyeing, in particular to a dyeing process capable of effectively improving white spots of an elastic fabric. The invention provides a dyeing process capable of effectively improving the white spots of the elastic fabric. On the basis of the conventional dyeing process, after the basic desizing step, the desizing treatment way in a cylinder isperformed again, in the desizing step and the in-cylinder desizing step, a desizing solution of a specific constitution and content is adopted, the emulsion breaking and back-dipping phenomenon of the silicone oil can be effectively improved, the white spot problem easy to form when in dyeing can be greatly avoided, the success rate of the elastic fabric dyeing process is increased from less than30 percent to 95 percent or above, the production efficiency is greatly improved, and the production cost is effectively reduced.

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...
