Abstract: New spinning finishes TDS-2000 for large capacity PET staple fiber was built from high-carbon alcohol phosphate as mainly antistatic,and ether-type or ester-type non-ionic surfactant and then was gone on several different industrial application research.The finishes were supplied with remarkable properties such as antistatic,membrance strength,gliding property,cohesion property compared with imported finishes on industrial application and performance evaluation.The results show TDS-2000 finishes meet the requirements of PET staple fiber production with good spinning ability and can take the place of the imported ones.
