In the textile printing production process, foaming of the printing paste is a common and troublesome problem. The presence of foam not only causes blurred edges of the printed pattern and surface defects such as pinholes or fish eyes, seriously affecting the aesthetics and quality of the finished product, but also reduces production efficiency and increases the rework rate and raw material loss. How to eliminate foam efficiently and durably and ensure a smooth printing process and perfect results has become a core concern for many producers.
In response to this market pain point, Chemi Tech, drawing on its deep experience in chemical additive research and development, has launched a series of high-efficiency printing paste defoamers. Our solution is not simply adding a product but, based on an in-depth understanding of the foam generation mechanisms (such as air entrained by mechanical stirring and the action of surfactants), provides comprehensive support from prevention to elimination.
The specific solution and application steps are as follows: First, in the selection stage, we recommend targeted model selection based on your paste system (such as water-based or a specific resin system) and production process (manual table printing or high-speed rotary screen printing). Chemi Tech defoamers have excellent compatibility, can quickly penetrate and break the foam film, and at the same time avoid affecting the leveling property and bonding strength of the paste.
Second, in the application stage, the correct addition method is key. We recommend adding the recommended amount of defoamer evenly during stirring in the paste preparation stage so that it disperses fully. For paste that has already produced foam, it can also be added directly with moderate stirring to defoam quickly. The dosage is usually very low, but the long-lasting foam-suppressing effect is remarkable and can keep the entire printing process stable.
We once helped a customer focusing on fashion fabric printing deal with a stubborn foam problem on its high-speed printing machine. The additive the customer originally used had insufficient foam-suppressing ability under high-speed operation, causing irregular white spots in the pattern during continuous production. After adopting the defoamer scheme customized by Chemi Tech, the foam was effectively controlled at the batching stage and the paste remained foam-free throughout several hours of production; ultimately the printed pattern was clear and sharp, customer satisfaction improved significantly, and production costs were reduced thanks to fewer defective products.
Choosing Chemi Tech printing paste defoamers means choosing reliable quality assurance and professional technical support. We are committed to helping every customer overcome foam obstacles in production and achieve more efficient and higher-quality printing output.
