Abstract
Cut-resistant and abrasion-resistant yarns including blends of technical fibers and mineral, inorganic, or ceramic fibers of substantially the same length as the technical fibers, and methods for manufacturing yarns, are disclosed.
Claims17
A composite yarn, comprising:
- a blended core yarn, comprising;
- about 90% high performance polyethylene stretch broken technical fibers, and
- about 10% inorganic, mineral, ceramic, or filament fibers having a length substantially similar to a length of the high performance polyethylene stretch broken technical fibers;
- and
- at least one wrapping yarn comprising at least one of a high tenacity polyamide or a high tenacity polyester, wherein the at least one wrapping yarn is wrapped around the core to form the composite yarn having an EN5 cut-resistance level and having dimensions that enable the composite yarn to be knitted with an 18 gauge needle.

A composite yarn, comprising:
- a blended core yarn, comprising:
- about 90% stretch broken technical fibers;
- and
- about 10% inorganic, mineral, ceramic, or filament fibers having a length substantially similar to a length of the stretch broken technical fibers;
- and
- at least one wrapping yarn comprising at least one of a high tenacity polyamide or high tenacity polyester, wherein the at least one wrapping yarn is wrapped around the blended core yarn to form the composite yarn having a denier of 260 or less and a EN5 cut-resistance level.
3 more elements
A composite yarn, comprising:
- a blended core yarn comprising about 90% high performance polyethylene stretch broken technical fibers, and about 10% inorganic, mineral, ceramic, or filament fibers having a length substantially similar to a length of the high performance polyethylene stretch broken technical fibers;
- and
- at least one wrapping yarn comprising at least one of a high tenacity polyamide or a high tenacity polyester, wherein the at least one wrapping yarn is wrapped around the core to form the composite yarn having an EN5 cut-resistance level, and wherein the denier of the composite yarn is between 70 and 221 denier.
