Abstract
Polyolefin fibers, primarily polypropylene fibers, having improved properties are provided. The ability to produce fibers having an improved balance of properties including increased tenacity, modulus and elongation, is accomplished by incorporating from 1 to 10 weight percent aromatic hydrocarbon resin in the polypropylene fiber-forming composition which can be based on a propylene homopolymer or copolymer or blend of these propylene polymer resins with a non-propylene-containing resin.
