During the processing of textiles, it is necessary to contact various dyes and additives. These additives, especially surfactants such as detergents, penetrants, emulsifiers and levelling agents, are prone to foaming when subjected to mechanical vibration. Foam is a dispersion of air in water or some liquids. 
During fabric processing, the contact surface between the liquid and the fabric will be reduced, resulting in uneven processing, which will seriously affect production and product quality. 
To eliminate foam, measures such as static, heating or decompression can be used, but in order to quickly eliminate foam or avoid foam generation in the printing and dyeing processes, it is necessary to add anti-foaming agents for textile printing and dyeing. 
After the defoamer is added to the working fluid, it becomes a solution, emulsion or dispersion, and is adsorbed on the surface of the bubble film. Because it has a lower surface tension than the bubble film, the surfactant or foaming substance can be attracted and pulled over, so that the surface viscosity of the foam liquid film is reduced, and the film becomes thin and cracked locally.
Defoamer is an important auxiliary agent in textile processing, and is widely used in textile printing and dyeing processes. 
In the textile printing and dyeing production process, such as printing, dyeing, applying chemical fiber oil agent, etc., a large amount of foam is generated. In the occasion of vigorous stirring, such as high temperature, overflow dyeing, high pressure spray and other processes, it is particularly intense. 
A large number of foams cause fabrics to float and uneven dyeing, and other problems need to be added.
