The duration of the effect of defoamer for textile&dyeing depends on many factors, such as the type, concentration, method of use, and environmental conditions of the defoamer.Generally speaking, if the defoamer can be evenly distributed in the textile and dyeing system and the environmental conditions are relatively stable, the defoaming effect can last from several hours to several days.

However, in the actual production process the defoaming effect of the defoamer may be affected by various factors. For example, in a high temperature and high humidity environment, the volatilization rate of the defoamer will be accelerated and the defoaming effect may be weakened. In addition, if the textile printing and dyeing system contains a large amount of surfactants or other chemicals, it may also affect the effect of the defoamer.

Therefore, in order to maintain the defoaming effect of the defoamer, it is recommended to conduct a small sample test before use to determine the best type and dosage, and replenish the defoamer in time according to the actual production situation. At the same time, attention should be paid to maintaining the stability of the environmental conditions, avoiding large changes in temperature and humidity, and operations such as excessive stirring and scraping, so as to maximize the defoaming effect of the defoamer.

Defoamers for textile&dyeing is a chemical used to remove foam generated in the textile printing and dyeing process. In the textile&dyeing process, when the dye or printing agent is combined with the fiber, it is usually necessary to heat or stir, which will cause the system to produce foam, thus affecting the quality and production efficiency.Therefore, defoamer are needed to remove such foam.

Defoamers for textile&dyeing are usually made of ingredients such as silicone and polymer composites, which can reduce the surface tension of the dye and printing agent, destroy the formation of foam, and ensure that the dye or printing agent is fully combined with the fiber. Defoamer can be added to the dyeing bath or sprayed on the surface, and the defoaming effect is very obvious.

In addition, according to different processes and the reasons for the generation of foam, textile printing and dyeing defoamers also have different types and uses. For example, in the weaving sizing process, in order to achieve a low-foam or no-foam effect, a defoamer is needed; in the dyeing and printing process, in order to eliminate the foam generated by substances such as surfactants, a defoamer is also needed.
