Abstract:
A cut-resistant multicomponent fiber comprising:(a) a first component comprising a first fiber-forming aromatic polyamide polymer and a hard filler, 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 based on the total weight of the fiber, 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 second component comprising a second unfilled fiber-forming aromatic polyamide polymer, wherein said 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 fiber by at least 10% compared with a fiber without said filler as measured by the Ashland Cut Protection Performance Test.
