MANUFACTURING METHOD OF POLYESTER CONJUGATED FIBER FOR ARTIFICIAL HAIR

摘要

The invention offers a method for manufacturing multifilament for artificial hair. Polyester copolymer (B) is produced from a mixing compound as a general form (I) and organic sulfone acid metallic salts to common polyester polymer (A) as a core component during polymerization. It is fused and mixed with polyester polymer (A), producing mixed polymer (C); then this polymer as an initial component is extracted and alkalified producing polyester multifilament for artificial hair which is used as a grey yarn for toupees, fashion wigs or wigs like natural hair.
