Polyester is a highly polar polymer, generally using a relatively high molecular weight of internal and external lubricants. Commonly used stearic acid, hard fat alcohol, lignite acid and its derivatives (soap, ester), tri-hydroxy stearic acid glycerol ester, B-supported double hard lipid diamine. TAF is the introduction of polar groups on the basis of B-bis fatty acid amide, the structure of which is a low relative molecular mass BAB type copolymer. The polar groups of Taf can be strongly attracted by the van der Waals force at the end of the long chain of coupling agent, and the solvent chain segments are compatible with the polyester matrix. Therefore, the experiment chooses lubricant TAF.
