Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
99 words
A method of preparing cotton blend yarns for durable fabrics comprising: a. Forming a staple fiber blend of from about 35 to 90 weight % cotton fiber, about 10 to 50 weight % organic polymeric fiber having a modulus of at least 200 g/dtex and optionally up to 55 weight % of other fiber having a modulus of less than 100 g/dtex; b. Spinning the fiber blend to form a continuous yarn; c. Wetting the yarn thoroughly with an aqueous bath; d. Drying the wet yarn under tension of from 0.2 to 2 g/dtex; and e. Collecting the yarn.
Claim 2
Independent Claim
99 words
A method of preparing cotton blend yarns for durable fabrics comprising: a. Forming a staple fiber blend of from about 35 to 90 weight % cotton fiber, about 10 to 50 weight % organic polymeric fiber having a modulus of at least 200 g/dtex and optionally up to 55 weight % of other fiber having a modulus of less than 100 g/dtex; b. Spinning the fiber blend to form a continuous yarn; c. Wetting the yarn thoroughly with an aqueous bath; d. Drying the wet yarn under tension of from 0.2 to 2 g/dtex; and e. Collecting the yarn.
Claim 3
Dependent Claim
23 words
A method according to claim 1 wherein the organic polymer fiber having a modulus of at least 200 g/dtex is poly(p-phenylene terephthalamide) fiber.
Claim 4
Dependent Claim
12 words
A continuous yarn prepared by the process of claims 1 or 2.
