Abstract
A machine knittable hybrid yarn is disclosed. The hybrid yarn includes one or more electrically non-conductive yarns and two or more electrically conductive wires wrapped around the electrically non-conductive yarns. The electrically conductive wires have an exterior layer of an insulated material. The electrically non-conductive yarns include a majority fraction of an overall cross-section of the hybrid yarn. The two or more electrically conductive wires are wrapped around the one or more electrically non-conductive yarns at between 1 and 15 twists per inch. The one or more electrically non-conductive yarns are 1500 denier or finer.
Claims20
A machine-knittable hybrid yarn, comprising:
- one or more electrically non-conductive yarns;
- and
- two or more electrically conductive wires wrapped around the electrically non-conductive yarns, the electrically conductive wires have an exterior layer of an insulating material,
- wherein the electrically non-conductive yarns comprise a majority fraction of an overall cross-section of the hybrid yarn,
- wherein the two or more electrically conductive wires are wrapped around the one or more electrically non-conductive yarns at between 1 and 15 twists per inch, and
- wherein the one or more electrically non-conductive yarns are 1500 denier or finer.
A method of making a machine-knittable hybrid yarn, the method comprising:
- wrapping, in a single process, two or more electrically conductive wires around one or more electrically non-conductive yarns, the electrically conductive wires each having an exterior coated with an insulating material,
- wherein the electrically non-conductive yarns comprise a majority fraction of an overall cross-section of the hybrid yarn, and
- wherein the one or more electrically non-conductive yarns comprise at least one:
- Ultra High Molecular Weight Polyethene (UHMWPE), Polybenzimidazole (PBI), Polyphenylene Benzobisoxazole (PBO), High Strength Polyester, Liquid-Crystal Polymer (LCP), or spider silk.
A machine-knittable hybrid yarn, comprising:
- one or more electrically non-conductive yarns;
- and
- two or more electrically conductive wires wrapped around the electrically non-conductive yarns, the electrically conductive wires having an exterior layer of an insulating material,
- wherein the electrically non-conductive yarns comprise a majority fraction of an overall cross-section of the hybrid yarn,
- wherein the two or more electrically conductive wires are wrapped around the one or more electrically non-conductive yarns at between 1 and 15 twists per inch, and
- wherein the one or more electrically non-conductive yarns are fire retardant and self-extinguishing.
