    • The present invention relates to a process for producing a polyphenylene sulfide multifilament yarn, a polyphenylene sulfide multifilament yarn and the use of a polyphenylene sulfide multifilament yarn. The process for producing a polyphenylene sulfide multifilament yarn is characterized in that only after time period between 0.1 sec and 0.3 sec after leaving the spinneret the filaments of the spun yarn are subjected to an active cooling stage. The Polyphenylene sulfide multifilament yarn having a filament linear density of 5 dtex to 30 dtex, an overall linear density of 500 dtex to 2500 dtex, a breaking tenacity in the range of 50 cN/tex to 80 cN/tex and an elongation at break of 8% to 16% for a yarn with a breaking tenacity in the range of 60 cN/tex to 80 cN/tex and an elongation at break of 16% to 30% for a yarn with a breaking tenacity in the range of 50 cN/tex to 60 cN/tex.
    • 本发明涉及聚苯硫醚复丝纱线,聚苯硫醚复丝纱线的制造方法以及聚苯硫醚复丝纱线的使用。 聚苯硫醚复丝纱的制造方法的特征在于,在离开喷丝头后仅0.1秒〜0.3秒的时间段之后,将细纱的长丝进行活性冷却阶段。 长丝线密度为5dtex〜30dtex,总线性密度为500dtex〜2500dtex,断裂强度为50cN / tex〜80cN / tex,断裂伸长率的聚苯硫醚复丝纱线 对于断裂强度在50cN / tex至80cN / tex的范围内的断裂强度为18cN / tex至80cN / tex,断裂伸长率为16%至30%的纱线为8%至16% tex至60 cN / tex。
