defoamer for textile auxiliary 

Large amount of foam is produced during the wet processing of textile dyeing and finishing because of the using textile auxiliaries, which affect the production operation, the production capacity go down, product quality would be degraded.  Therefore, it must remove the harm ful foam from the textile processing. By the way, it has been proved that adding defoamer is the best efficient way to eliminate foam in the textile processing.

There are many kinds of defoamers, which are usually classified into silicon and non-silicon.

(1) Non-silicone defoamer: mostly single components, such as isooctyl alcohol, soap tablets, tributyl phosphate, kerosene and polyether. It is also possible to compound several ingredients to improve efficacy. The use of emulsifiers such as fatty acids and esters to emulsifie fatty alcohols, fatty acid amides, polyethers and mineral oils into aqueous emulsions is also a commonly used defoaming agent.

(2)  Silicone defoamer: We classify the silicone emulsion defoamer according to the emulsifying system and processing method:

-- Emulsifying system based on silicone oil and food grade emulsifier, produced by reverse phase processing method Defoamers are called S series defoamers.

-- Emulsification system based on modified polyether, silicone oil and food grade emulsifier, and defoaming agent produced by reverse phase processing method is called T series defoamer.

-- Emulsifying system based on polyether modified silicone oil, the defoaming agent produced by reverse phase processing method is called X/C series defoaming agent.

Dimethyl silicone oil, specific silica as the main defoaming component, a variety of nonionic surfactants as emulsifier, according to defoaming mechanism, compounding principle and emulsification technology, dimethyl silicone oil and specific silica The ratio of the ratio, the amount of the emulsifier, the amount of the thickener, the order of the addition, etc. to the performance of the product were studied to determine the optimum process conditions for the compounding. The antifoaming agent developed has good high temperature resistance, defoaming property and foam suppression. Sex and stability, and the equipment and production process are simple.
