    In the textile industry, sizing is an important process, the purpose of which is to improve the strength, wear resistance and weavability of yarn. However, in the process of textile sizing, a large amount of foam is often generated, which not only affects the quality and effect of sizing, but also increases production costs and environmental pollution. Therefore, the application of textile sizing defoamer is particularly important.
    The working principle of textile sizing defoamer is mainly to reduce the strength of the foam film by reducing the surface tension of the liquid, thereby causing the foam to rupture. The defoamer molecules can form a monomolecular film on the surface of the foam film, which will destroy the stability of the foam film, making the foam film thinner and ruptured.

    In the textile sizing process, there are two main methods of applying defoamers: one is the direct addition method, that is, the defoamer is directly added to the slurry, and it is evenly dispersed by stirring, etc., so as to achieve the purpose of defoaming; the other is the indirect addition method, that is, the defoamer is added to a specific part of the slurry circulation system, such as a filter, a pump, etc., and the defoaming is achieved by full contact with the slurry.

    In short, textile sizing defoamers play an important role in the textile sizing process. By selecting the right defoamer and application method, the foam generated in the textile sizing process can be effectively eliminated, the sizing quality and effect can be improved, and production costs and environmental pollution can be reduced. With the development of the industry and the advancement of technology, the performance and application of textile sizing defoamers will continue to be optimized and expanded.
