Abstract
A composite yarn is disclosed herein having a plurality of first synthetic fibers having a tenacity of greater than or equal to 1 N/tex; and a plurality of second fibers having a tenacity of less than or equal to 0.95 N/tex; wherein each of the first synthetic fibers and the second fibers are stretch broken and/or cut; and wherein each of the first synthetic fibers and the second fibers have an average length from about 75 mm to about 150 mm. A method of making the composite yarn and articles formed from the composite yarn are also disclosed.
Claims16
A composite yarn, comprising:
- a plurality of first synthetic fibers having a tenacity of greater than or equal to 1 N/tex;
- and
- a plurality of second fibers having a tenacity of less than or equal to 0.95 N/tex;
- wherein each of the first synthetic fibers and the second fibers are stretch broken to have an average length from about 75 mm to about 150 mm;
- wherein the first synthetic fibers comprise para-aramid, meta-aramid, copolyamides, carbon fibers, HPPE, UHMWPE, reinforced HPPE, reinforced UHMWPE, or a combination thereof;
- and
- wherein the second fibers comprise elastomers, viscose, nylon, acrylic, modacrylic, a polyester, a polyolefin, silica fibers, ceramic fibers, basalt fibers, metal fibers, glass fibers, or a combination thereof.
A composite yarn, comprising:
- a plurality of first synthetic fibers having a tenacity of greater than or equal to 1 N/tex;
- and
- a plurality of second fibers having a tenacity of less than or equal to 0.95 N/tex;
- wherein each of the first synthetic fibers and the second fibers are stretch broken and/or cut;
- wherein each of the first synthetic fibers and the second fibers have an average length from about 75 mm to about 150 mm;
- and
- wherein the composite yarn further comprises electrically conductive hairy fibers, each comprising a plurality of appendages extending away from a center of the hairy fiber, wherein a portion of the plurality of appendages extend away from an outer surface of the composite yarn,
- wherein an article produced from the composite yarn has a vertical resistivity of less than or equal to about 108 Ohm when determined according to EN 16350,
- wherein the second fibers comprise the conductive hairy fibers, and/or
- wherein the composite yarn comprises the first synthetic fibers, the second fibers, and the conductive hairy fibers.
A composite yarn, comprising:
- a plurality of first synthetic fibers having a tenacity of greater than or equal to 1 N/tex;
