摘　　要：采用国产注塑级聚丙烯切片并添加降温母粒的方法在进口设备上生产丙纶ＢＣＦ。生产中适当调整降温母粒添加比例，提高纺丝箱体温度，优化冷却条件和拉伸工艺，生产出的丙纶ＢＣＦ断裂强度可达１．７０～１．９０ｃＮ／ｄｔｅｘ。PP BCF was obtained from domestic plastic grade polypropylene chips embodied chemical degradation masterbatch on imported machine. The breaking strength of PP BCF increased to 1 70￣1 90 cN/dtex by appropriately adjusting the amount of chemical degradation masterbatch, increasing spin manifold temperature and optimizing cooling conditions and drawing process.
