    • The present invention relates to a method for producing a fiber for an artificial hair comprising: (a) pre-mixing a polyvinyl chloride resin mixture which contain 90 to 96% by weight of a polyvinyl chloride resin, 3 to 7% by weight of a stabilizer and 1 to 3% by weight of a lubricant at 90 to 140° C., mixing 20 to 80% by weight of a polyvinyl chloride resin mixture and 20 to 80% by weight of acryl-copolymer to obtain a polyvinyl chloride/acryl-copolymer blends composition; (b) melt-extruding said mixed resin composition through an extruder at 100 to 210° C. to obtain a pellet; (c) inputting said pellet into an spinning machine, melt-spinning at 150 to 220° C. to obtain filament; (d) drawing said melt-spinned filament to have a fineness of 20 to 100 denier; and (e) passing said drawn filament through heat-setting machine of 100 to 150° C. to fix the property of the filament.
    • 本发明涉及一种人造毛发纤维的制造方法,其特征在于:(a)预先混合含有90〜96重量%的聚氯乙烯树脂的聚氯乙烯树脂混合物,3〜7重量% 稳定剂和1至3重量%的润滑剂,在90至140℃下,混合20至80重量%的聚氯乙烯树脂混合物和20至80重量%的丙烯酸共聚物,得到聚氯乙烯/丙烯酸酯 - 共聚物混合物组成; (b)通过挤出机在100-210℃熔融挤出所述混合树脂组合物以获得颗粒; (c)将所述颗粒输入纺丝机中,在150-220℃熔融纺丝以获得长丝; (d)拉伸熔融纺丝的细丝,其细度为20至100旦尼尔; 和(e)将所拉伸的细丝通过热定型机100至150℃以固定丝的性质。
