Making process of polypropylene fiber with mosquito repelling function

The present invention is the making process of polypropylene fiber with mosquito repelling function. The making process includes mixing powdered polypropylene and mosquito repellant, which accounts for 5-10 wt% and is selected from dimethyl phthalate, benzethazet acetofenate, methothrin or their mixture; melt pelletizing in a screw bolt extruder at 150-210 deg.c to produce agglomerate; melt mixing the agglomerate with common polypropylene grain in a screw bolt extruder at 150-210 deg.c to produce spinning material with mosquito repellant content of 1.0-3.0 wt%; and melt spinning of the driedspinning material in a screw bolt extruder at 220-260 deg.c to produce filament or short staple, with the winding speed being 700-2500 m/min. 一种制造具有避蚊功能聚丙烯纤维的方法，过程为：粉状聚丙烯树脂与驱蚊剂均匀混合，驱蚊剂的含量控制为5～10wt％，驱蚊剂取自邻苯二甲酸二甲酯、三氯杀虫酯或甲醚菊酯中的一种化合物或两种以上化合物的混合物，然后采用螺杆挤出机进行共混加热熔融造粒制得母粒，螺杆挤出机的加热温度为150～210℃；上述得到的母粒与普通聚丙烯粒子混合后采用螺杆挤出机进行共混熔融造粒制得纺丝原料，螺杆挤出机的加热温度为150～210℃，纺丝原料中驱蚊剂的含量控制为1.0～3.0wt％；纺丝原料经干燥后在螺杆挤出机中进行加热熔融纺丝制得长丝或短纤维，纺丝温度为220～260℃，卷绕速度为700～2500m/min。
