In the textile printing and dyeing industry, the printing process is an important link to give fabrics rich and colorful patterns and colors. As the core material of the printing process, the performance of the printing slurry directly affects the printing effect. However, in the preparation and use of printing slurry, the foam problem often brings many troubles to the printing and dyeing work. The emergence of printing slurry defoamer has successfully resolved this problem and become a key auxiliary agent to ensure the quality of printing.

The reasons for the foaming of printing slurry are relatively complex and involve many aspects. From the perspective of the composition of the slurry itself, the various chemical additives it contains are important factors in the generation of foam. For example, although additives such as thickeners and emulsifiers play a key role in improving the rheological properties, stability and dispersibility of the slurry, most of them are surface active and easily reduce the surface tension of the slurry, prompting air to form bubbles in the slurry and exist stably.

The defoaming function of printing slurry is mainly achieved through two key action mechanisms. First, the active ingredients in the defoamer have a lower surface tension than the slurry, and can quickly migrate to the foam surface to form a new low surface tension film on the foam surface. This film will destroy the original surface tension balance of the foam, thinning and breaking the liquid film on the foam surface, thereby achieving the purpose of defoaming.

Printing slurry defoamer plays an indispensable role in the textile printing and dyeing industry. It is a key auxiliary agent to solve the problem of printing slurry foam and ensure the quality of printing. With the continuous development of textile printing and dyeing technology and the increasing requirements for printing quality, printing slurry defoamers are also constantly innovating and upgrading. In the future, it will develop in a more efficient, environmentally friendly and multifunctional direction, provide strong support for the continued prosperity of the textile printing and dyeing industry, and help more exquisite printed fabrics to enter the market.
