Abstrakt
The commercial entangled ultra-high molecular weight polyethylene (UHMWPE) shows a high degree
of entanglement in macromolecular chains, and our research group used the modified Ziegler-Natta
catalyst to prepare UHMWPE with a low degree of entanglement to improve its melt processability. The
application on plate-like material formed by injection or hot pressing has been explored, and at present
we would like to expand the application field to fibers and textiles. The disentangled UHMWPE is added
into the high-density polyethylene (HDPE) matrix by using twin screw extrusion for subsequent melt
spinning process. The experimental results show that the addition of ultra-high molecular weight
polyethylene improves the mechanical properties of fibers, and the effect varies with the addition
amount. The addition amount of UHMWPE is optimized as 45 wt.%, which significantly improves the
tensile strength of HDPE from 3.7 to 7.7 cN/dtex.
