Abstract
This invention is a cut resistant article comprising a cut resistant jacket surrounding a less cut resistant member. The jacket comprises a fabric of yarn and the yarn consists essentially of a high strength, longitudinal strand having a tensile strength of at least 1 GPa. The strand is wrapped with another fiber or the same fiber. In another embodiment, the invention is a highly cut resistant yarn of at least two nonmetallic fibers. One fiber is inherently cut resistant like high strength polyethylene, polypropylene or aramids. The other fiber in the yarn has a high level of hardness.
Claims15
A protective fabric made from cut resistant yarn comprising at least two dissimilar non-metallic fibers, at least one non-metallic fiber being flexible and inherently cut resistant and the other of said non-metallic fibers having a level of hardness at above about three Mohs on the hardness scale.
A process to make a cut resistant fabric comprising combining a plurality of dissimilar nonmetallic fibers to form a yarn and then constructing a fabric from said yarn, at least one said nonmetallic fiber being flexible and inherently cut resistant and at least one other said nonmetallic fiber having a level of hardness at about 3 on the Mohs hardness scale.
