Application Of Defoamer In Textile Printing And Dyeing Industry

Now people's living conditions are good, and the demand for clothing and textile decoration is also constantly deepened, so the textile printing and dyeing processing industry is developing faster and faster.

There are always a lot of bubbles in the process.

The emergence of foam will have a certain impact on printing effect, and the elimination of printing and dyeing textile foam is imminent. Let's introduce the use of textile printing and dyeing defoamer.

Reasons for foaming in textile printing and dyeing:

1. Sizing process and sizing process.

High speed mobile process can lead to many bubbles.

2. During the pretreatment process, the product is desizing.

When bleaching and washing are used for scouring and bleaching agents and cleaning lotions, high temperature scouring is used to produce foam for better and more uniform penetration.

3. In the process of medium temperature dyeing and high temperature dyeing, the vibration of mechanical operation leads to foam.

4. The mixing process and the color paste produce bubbles during the printing process.

The hazards of foaming in textile printing and dyeing:

1.

2, prolong the dye reaction cycle; 3, affect the quality of the final product; 4, the production capacity is greatly restricted; 5, it is not conducive to accurate measurement; 6, it will cause some pollution to the environment.

After we have seen, we have a certain understanding of the causes and hazards of textile printing and dyeing China foam. Therefore, it is necessary to eliminate foam in the printing and dyeing industry.

Textile printing and dyeing defoamer has high temperature resistance, strong alkali resistance and strong anti foaming ability.

When added to the working fluid, it becomes a solution, emulsion or dispersion and adsorbed on the surface of the bubble film.

Because it has a lower surface tension than the bubble film, it can attract the surfactant or foaming material to pull the surface viscosity of the foam liquid film down, partially thinning and cracking.
