| Abstract: | 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. |
