PURPOSE:To suppress effectively the gluing between fibers and obtain the titled fibers for ropes, etc., by spinning a solution of a polyolefin having a specific weight-average molecular weight, applying a treating agent, e.g. silicone based agent, to the resultant gelatinous filaments after extracting a solvent therefrom, and hot-drawing the resultant filaments under specific conditions. CONSTITUTION:A solution containing 0.5-15wt% polyolefin polymer, e.g. high- density polyethylene, having >=5X10<5> weight-average molecular weight is spun to give gelatinous filaments, and the solvent is extracted. A silicone based or fluorine based treating agent or both agents in an amount of 0.5-20wt% are applied to the gelatinous filaments, and the resultant filaments are dried or fibers during the drying are hot-drawn at a temperature of the melting point of the polyolefin based polymer -70 deg.C lower than he melting point at >=10 times draw ratio to give the aimed fibers.
