Abstract
Heat-melt adhesive propylene polymer fibers which can be produced with a superior spinnability are provided, which comprise a resin consisting of (A) 50-100% by weight of a crystalline propylene terpolymer consisting of specified amounts of propylene, butene-1 and ethylene, and (B) 0-50% by weight of a substantially non-crystalline ethylene-propylene random copolymer; said fibers consisting of single fibers of said resin alone or composite fibers having said resin as one component thereof.
