Textile auxiliaries can be divided into two types: pre-treatment auxiliaries and post-treatment auxiliaries. They are chemicals needed in the production and processing of textiles. They play an important role in improving the product quality and added value of textiles. They have properties such as softness, wrinkle resistance, shrinkage resistance, waterproofness, antibacterial, antistatic, and flame retardant. They can also improve dyeing and finishing processes, save energy, and reduce processing costs. However, foam problems often occur in the production and use of textile auxiliaries, so textile auxiliaries defoamers are needed to solve the foam problem.

The use of pre-treatment auxiliaries is mainly to remove natural or artificial impurities on the fabric and give full play to the excellent properties of the fabric. They mainly include wetting agents, penetrants, bleaching agents, detergents, etc. The use of post-finishing auxiliaries is mainly to improve the appearance and internal quality of the fabric through physical and chemical processing, improve the feel, improve performance, or give the fabric antibacterial, wrinkle-proof, flame-retardant, antistatic, anti-toxic and anti-insect, anti-fouling and anti-oil functions.

A large amount of surfactants are often used as basic raw materials in the production of textile auxiliaries. These ingredients have foaming properties and will cause a large amount of foam to be generated. These textile auxiliaries are affected by temperature and pH changes under high shearing effects such as production stirring, which will cause foam to be generated. Changes in textile structure will cause foam to be generated. The greater the change, the worse the foaming index test results. In addition, uneven connection ability, yarn structure and finishing can also cause foaming.

Excessive foam will bring some adverse effects：

1.) Foam generation will have a certain impact on the performance and quality of textile auxiliaries, which will reduce their softness, wrinkle resistance, shrinkage resistance, waterproofing and other functions, and cause quality problems;

2.) If the foam is not eliminated in time, it will remain inside the fabric, slowing down the production progress and processing procedures of textile auxiliaries, resulting in reduced production efficiency and increased costs;

3.) A large amount of foam will cause the production and processing system of textile auxiliaries, which not only affects the surrounding sanitary environment, but also leads to waste of raw materials.

In the face of the many hazards caused by the foaming of textile auxiliaries, you can choose to use a textile auxiliaries defoamer, which has the characteristics of fast defoaming speed and long foam suppression time, and can effectively solve the problem of large amounts of foaming in textile auxiliaries; it has a wide range of applications, is acid and alkali resistant, and can stably eliminate the foam in textile auxiliaries under high temperature, strong acid and strong alkali environments. It has stable chemical properties and will not affect the performance quality of textile auxiliaries after use.
