Defoamer SP853 ,S099,M688 are special for textile sizing step with good high temperature resistance, good stability, non-corrosive, non-toxic, non-flammable, non-explosive, no adverse side affect.

　　Textile sizing agent have natural and chemical synthesis two types ,It is designed to prevent or reduce yarn and thread breakage during weaving and improve work efficiency, and chemical sizing agent is widely used in textile sizing processing,Emulsion polymerization is the main method to produce chemical sizing agent, during this step will have lots of foams,add defoamer before the emulsion getting polymerization will help to get the best effective for foam control,this can increase the stability of the finished products.
