Application of Defoaming Agent in Dyeing and Finishing Production

By : -- 2019-02-20 17:25:18

In the process of printing and dyeing of knitted fabrics, foaming causes the fabric to float on the surface of the water, and in severe cases, jamming (overflow jet dyeing machine) occurs. At this time, people often want to use low foaming surfactants to meet the needs of various fast and efficient processes, so defoamers become the preferred additives for technicians. The antifoaming agent infiltrates into the surfactant foam by using an organic compound such as an alcohol, an ether or a silicone oil, and extends to the square to make the foam continuously thin, and destroys the oriented molecular adsorption layer formed on the gas-liquid surface (interface) until the foam is broken.

In the past, many printing and dyeing companies did not understand the amount and performance of the defoaming agent when using the antifoams. Therefore, when several kinds of cylinders were not found, the surface of the fabric was stained with an irregular shape of oil. When I first encountered this phenomenon, I couldn’t figure out where so many oils came from, because the oil (what color, which is the color of the oil) attached to the surface of the fabric is very bright, and it is penetrated by hand. The fabric, if it is stained, it will not go clean. After many reasons to find out, the oil was analyzed by the antifoaming agent demulsification. Once the fabric is contaminated with this dirt, it is difficult to remove it. After many experiments, it is known that the greater the amount of antifoam, the more serious such phenomena. Chemical fiber fabrics such as polyester cotton and pure polyester are more obvious (there is no such phenomenon in machines without antifoams).


Defond is a manufacturer with 16 years of application experience. It has far more defoaming technology than other antifoaming agents in the market. From the above cases, we prove the strength of our Defond antifoam. We have a group of excellent defoaming engineers, and An independent laboratory that facilitates defoaming experiments with foams that are difficult for customers to solve.
