Abstract

See full text

The present invention relates to a polyolefin fiber comprising polymeric structures, wherein the polymeric structures individually comprise a polycondensate and a functionalized polymer, and the polyolefin fiber is a gel-spun high-performance polyethylene fiber that has a tenacity of at least 1 N/tex. The polymeric structures are immiscible with and dispersed in the polyethylene fiber. The gel-spun high-performance polyethylene fiber is a gel-spun ultrahigh molecular weight polyethylene fiber. The present invention further relates to a process for making the polyolefin fiber comprising the steps of: melt-mixing the polycondensate or a polycondensate containing at least one additive, the functionalized polymer, and optionally the thermoplastic polymer and/or the at least one additive, to form polymeric structures; mixing polyolefin powder, the polymeric structures and a solvent to form a mixture; and spinning and drawing the mixture obtained in step ii) to form the polyolefin fiber comprising the polymeric structures.
