Abstract
A cut-resistant, machine knittable, composite yarn that utilizes a yarn or fiber strand or component of normal strength (no greater than 10 grams per denier tenacity) liquid crystal polymer, to provide a composite yarn of comparable high cut-resistance to composite yarns of similar construction that utilize high strength synthetic yarn or fiber. Also protective articles of apparel knitted from such yarn, specifically a cut-resistant protective glove.
Claims8
A cut-resistant yarn suitable for machine knitting, comprising a core, a first wrapping about the core and a second wrapping about the first, at least one of said core, first wrapping and second wrapping being comprised of cut-resistant liquid crystal polymer fiber having a tenacity of no more than 10 grams per denier wherein the core is comprised of said liquid crystal polymer fiber.
A cut-resistant yarn suitable for machine knitting having:
- a core comprised of a liquid crystal polymer fiber having a tenacity of no more than 10 grams per denier, a flexible metal strand;
- a wrapping of liquid crystal polymer fiber having a tenacity of no more than 10 grams per denier, and one or more additional wrappings of synthetic fiber none of which has a tenacity greater than 10 grams per denier.
A cut-resistant yarn suitable for machine knitting having a core comprised of a liquid crystal polymer fiber having a tenacity of no more than 10 grams per denier and a strand of wire, and having wrappings comprised of a wrapping of liquid crystal polymer fiber having a tenacity of no more than 10 grams per denier, and two wrappings each of which is either nylon or polyester over the liquid crystal polymer wrapping.
