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.
Claims20
A composite yarn, comprising:
- a blended core yarn, consisting essentially of;
- about 80 to 95% high performance polyethylene stretch broken technical fibers, and
- 5 to 20% 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, consisting essentially of:
- 80 to 95% stretch broken technical fibers;
- and
- 5 to 20% 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.

A composite yarn, comprising:
- a blended core yarn consisting essentially of 80 to 95% high performance polyethylene stretch broken technical fibers, and 5 to 20% 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.
A method for making a cut resistant blended yarn that consists essentially of:
- about 80 to 95% stretch broken technical fibers, and
- 5 to 20% inorganic, mineral, ceramic, or filament fibers having a length substantially similar to a length of the high performance polyethylene stretch broken technical fibers,
- the method comprising:
- gel, wet, or dry-spinning the technical fiber with the inorganic, mineral, ceramic, or filament fibers, wherein the technical fibers and inorganic, mineral, ceramic, or filament fibers have a length and diameter that is substantially similar to a length and diameter of the technical fibers, to form a cut-resistant blended yarn.
