一种在聚苯硫醚纤维表面涂敷芳纶树脂保护层的工艺方法
摘要：
本发明公开了一种在聚苯硫醚纤维表面涂敷芳纶树脂保护层的工艺方法，采用硫化钠与对二氯苯为原料，在加入助剂和催化剂的溶液中合成生产聚苯硫醚树脂；将所述树脂采用熔融纺丝纺织成纤维原丝；纤维原丝进行热牵伸处理成成品纤维；所述聚苯硫醚成品纤维在浓度为10-12％wt温度为25℃的芳纶1414浓硫酸溶液中预浸渍涂敷后，再经后处理最后得到含有厚度为5-10微米芳纶1414树脂保护层的聚苯硫醚纤维产品。该聚苯硫醚复合纤维尤其适合作为专业用于火力发电、垃圾焚烧炉、化工过滤等专业过滤材料。
摘要（英）：

The invention discloses a process method of coating an aramid fiber resin protective layer on surface of polyphenylene sulfide fiber. The process is characterized by synthesizing and producing the polyphenylene sulfide resin by using sodium sulfide and p-dichlorobenzene as raw materials in a solution added with additives and catalysts; performing melt spinning for the resin to form fiber precursor; performing a hot-stretching treatment for the fiber precursor to form finished fiber; pre-immersing and coating the finished polyphenylene sulfide fiber in an aramid 1414 concentrated sulfuric acid solution with a concentration of 10 to 12 % by weight at a temperature of 25 DEG C, post-treating and finally obtaining the polyphenylene sulfide fiber product containing the aramid 1414 resin protective layer having a thickness of 5-10 microns. The composite polyphenylene sulfide fiber is especially suitable for being used as professional filter materials for thermal power generation, waste incinerators, chemical filtration, etc.
