Application of defoamer in textile printing and dyeing industry
Nov 27, 2018

Nowadays, people's living conditions are good, and the demand for textile and textile decoration is also deepening. Therefore, the textile printing and dyeing processing industry is developing faster and faster, so there are often many bubbles in the process of textile printing and dyeing. The appearance of foam will have a certain impact on the printing effect. Most of the elimination of printing and dyeing textile foam is imminent. Let's introduce the use of textile printing and dyeing defoaming agent to the Chinese paper industry.

Reasons for textile printing and dyeing:

1. The slurry sizing process and the high-speed movement of the yarn will cause many foams to appear.

2. In the pre-treatment process, when the desizing agent is used in the desizing of the product, and the bleaching and washing agent is used in the bleaching and washing, in order to penetrate the fabric better and more uniformly, the high-temperature scouring is used to cause the foam to be generated.

3. During the medium temperature dyeing and high temperature dyeing process, the mechanical operation vibration causes the foam to be generated.

4, the pulping process and the color paste in the process of mixing during the printing process to produce foam.

The danger of textile printing and dyeing:

 

1. A certain waste of raw materials and products; 2. Prolong the reaction cycle of dyes; 3. Affect the quality of the final product; 4. The production capacity is greatly limited; 5. It is not conducive to accurate measurement; 6. It will cause certain environmental impact. Pollution

 

After reading it, everyone has a certain understanding of the causes and harms of the textile printing and dyeing of Chinese foam. Therefore, it is very necessary to use the defoaming agent in the printing and dyeing industry to eliminate the foam. Textile printing and dyeing antifoaming agent has high temperature resistance, strong alkali resistance and strong foam breaking and foam suppressing ability. After being added to the working solution, it becomes a solution, an emulsion or a dispersion, and is adsorbed on the surface of the bubble film. Since it has a lower surface tension than the foam film, the surfactant or the foaming material can be drawn and pulled, so that the surface viscosity of the foam liquid film is lowered, locally thinned and broken.
