Alpaca fiber composite yarn
View Patent ↗This disclosure relates generally to a composite yarn comprising a core and an outer wrapping. The core comprises an alpaca fiber roving. The outer wrapping comprises a second fiber.
1 . A composite yarn comprising:
a twisted core comprising an alpaca fiber roving, wherein the alpaca fiber roving is twisted and spun to create the core having a twist density of from about 100 to about 750 twists per meter; and
an outer wrapping comprising a second fiber, wherein the alpaca fiber roving of the core is wrapped with the second fiber in an opposite direction to the twist of the core.
2 . The composite yarn of claim 1 , wherein the core consists of alpaca fiber.
3 . The composite yarn of claim 1 , wherein the core further comprises a second core fiber, wherein the second core fiber is different than the alpaca fiber roving.
4 . The composite yarn of claim 3 , wherein the second core fiber is blended with the alpaca fiber roving and twisted together to create the core.
5 . The composite yarn of claim 3 , wherein the alpaca fiber roving is twisted and spun upon itself, and plied and twisted with the second core fiber.
6 . The composite yarn of claim 1 , wherein the second fiber is a natural fiber or a synthetic fiber.
7 . The composite yarn of claim 1 , wherein the yarn resists microbial growth.
8 . The composite yarn of claim 1 , wherein the composite yarn is not treated with chemicals or other additives.
9 . The composite yarn of claim 1 , wherein the core twist density is from about 100 to about 200 twists per meter, about 200 to about 500 twists per meter, or about 500 to about 750 twists per meter.
10 . The composite yarn of claim 1 , wherein the second fiber of the outer wrapping is a natural fiber, optionally wherein the natural fiber is selected from the group consisting of a second alpaca fiber, alpaca fiber blend, goat fiber, sheep fiber, mink fiber, beaver fiber, ermine fiber, fox fiber, nutria fiber, opossum fiber, sable fiber, seal fiber, muskrat fiber, raccoon fiber, squirrel fiber, camel fiber, llama fiber, tree bark fiber, and bamboo fiber.
11 . The composite yarn of claim 1 , wherein the second fiber of the outer wrapping is a synthetic fiber, wherein the synthetic fiber is a polymer, optionally wherein the polymer is selected from the group consisting of spandex and nylon.
12 . A method of making a composite yarn comprising:
providing a twisted core comprising an alpaca fiber roving having a twist density of from about 100 to about 750 twists per meter, and
providing an outer wrapping comprising a second fiber wrapped in an opposite direction to the twist of the core.
13 . The method of claim 12 , wherein the alpaca fiber roving is blended with a second core fiber, and twisted together to create the core.
14 . The method of claim 12 , wherein the core comprises the alpaca fiber roving and a second core fiber, and wherein the core is made by mating or marrying the alpaca fiber roving with the second core fiber.
15 . The method of claim 12 , wherein the composite yarn is not treated with chemicals or other additives.
16 . The method of claim 12 , wherein the core is twisted to a twist density of from about 100 to about 200 twists per meter, about 200 to about 500 twists per meter, or about 500 to about 750 twists per meter.
