摘要
以远红外聚丙烯废料为原料 ,在普通涤纶纺丝设备上纺制再生远红外丙纶短纤维 ,并对造粒、干燥、纺丝成形、拉伸等工艺进行了探讨。远红外聚丙烯经过再造粒后 ,其熔体流动指数较原料高出 10左右 ,干燥温度一般控制 10 0～ 12 0℃ ,干燥时间 4～ 8h ,纺丝温度设定高于熔点 10 0℃左右 ,拉伸倍数 2～
The regenerated far-infrared polypropylene fiber was obtained from far-infrared polypropylene waste on a common PET fiber plant. The technological process of granulation, drying, fiber-formation and drawing was discussed. After granulation, the melt index of polypropylene chip was about 10 higher than original. The process conditions were controlled as followed: drying temperature 100～120℃, drying time 4～8 h, spinning temperature 100℃ higher than melting point, draw ratio 2～3.
