Document Type and Number:
WIPO Patent Application WO/2020/230809
Kind Code:
A1
Abstract:
Provided is a polyethylene fibre having outstanding anti-creep characteristics while having high strength. The present invention provides an ultra-high molecular weight polyethylene fibre including ethyl branches as side chains, characterised in that the ratio {(C2H5/1,000C)/(elongation stress)} of the number of ethyl branches per 1,000 carbon atoms (C2H5/1,000C) to the elongation stress of the polyethylene fibre (MPa) is 2-30 branches/1,000 carbon atoms/MPa.
