PURPOSE: To obtain the title fiber useful for slate, etc., having excellent adhesiveness to cement, showing excellent dispersibility during processing reinforcing fibers into a sheetlike material by blending a specific high-density PE with a given amount of an organosilane compound to give a composition, subjecting the composition to melt spinning, multi-stage drawing and irradiating the fibers with active energy line.
CONSTITUTION: A high-density PE having 0.950-0.970g/cm3 density, 0.1-2.0g/10 minutes melt index and a ratio of high load melt index/melt index of ≤40 is blended with 1.0-10.0wt.%, preferably 2.0-7.0wt.% organosilane compound such as vinyltriakoxysilane to give a composition, which is subjected to melt spinning, multi-stage drawing to give PE fibers. The PE fibers are irradiated with 0.5-30Mrad active energy such as electron beam to give the objective fibers. The fineness of the fibers is preferably 10-500d.
