Abstract:
A cut-resistant sheath/core fiber comprising:(a) a core comprising a fiber-forming polymer and a hard filler distributed uniformly in said core, said filler having a Mohs Hardness Value greater than 3, said filler being present in an amount of about 0.05% to about 20% by weight of said core, said filler being selected from the group consisting of a powder having an average diameter up to 20 microns, an elongated particle having an average length up to 20 microns, and mixtures thereof; and(b) a sheath consisting essentially of an unfilled second polymer; wherein said cut-resistant sheath/core fiber has a denier in the range of about 1 to about 50 dpf; wherein said filler is included in sufficient quantity to improve the cut resistance of said cut-resistant sheath/core fiber by at least 10% compared with a sheath/core fiber without said filler as measured by the Ashland cut Protection Performance Test.
