During high temperature textile processing, the generation of foam is common. During high temperature dyeing, dyes, auxiliaries interact with the high temperature environment. When the solution is stirred or circulated, air is drawn into it to form foam. Moreover, the physical and chemical changes of the textile fibers themselves during high temperature processing may also promote the generation of foam. At this time, high temperature resistant textile defoaming agents were born in this context.

In high temperature dyeing, the presence of foam may cause uneven dyeing of dyes, color spots, color flowers and other problems, affecting the color and color fastness of the fabric. A large amount of foam will occupy the space of the processing equipment, reduce the effective working volume of the equipment, and increase production costs.

High temperature resistant textile defoaming agents have a special molecular structure that can quickly migrate to the surface of the foam. On the surface of the foam, the defoaming agent molecules reduce the surface tension of the liquid film. Due to the imbalance of surface tension, the foam liquid film will gradually become thinner and break. This ability to adjust surface tension is still effective in high temperature environments, ensuring continuous defoaming during high temperature textile processing.

During the high-temperature processing of textiles, high temperatures above 100°C may be encountered. For example, the temperature can reach about 130°C during high-temperature and high-pressure dyeing. Defoamers will not only not lose their defoaming and antifoaming capabilities at such high temperatures, but will continue to play an effective role to ensure the smooth progress of the textile processing process.

With the continuous development of textile technology, the performance requirements for high-temperature resistant textile defoamers will continue to increase. In the future, defoamers will develop towards higher high-temperature resistance, stronger defoaming and antifoaming capabilities, and multifunctionality, and will continue to lead the high-quality development of the textile industry.
