Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
29 words
Woven or knitted fabric containing a plurality of naps composed of bundles of superfine fibers of less than 0.7 denier which are bound with a cured organic silicone polymer.
Claim 2
Dependent Claim
29 words
Woven or knitted fabric containing a plurality of naps composed of bundles of superfine fibers of less than 0.7 denier which are bound with a cured organic silicone polymer.
Claim 3
Dependent Claim
16 words
Woven or knitted fabric according to claim 1, characterized by the presence of fine nap ends.
Claim 4
Dependent Claim
21 words
Woven or knitted fabric according to claim 1 or 2, in which the superfine fibers have a thickness of 0.6-0.001 denier.
Claim 5
Dependent Claim
23 words
Woven or knitted fabric according to claim 1 or 2, in which the organic silicone polymer has a molecular weight of about 10,000-600,000.
Claim 6
Dependent Claim
37 words
Woven or knitted fabric according to claim 1 or 2, in which the amount of deposited organic silicone polymer is about 3-30 parts by weight per 100 parts by weight of the total fabric plus silicone polymer.
Claim 7
Dependent Claim
18 words
Woven or knitted fabric according to claim 1 or 2, in which the fabric is satin or velvet.
Claim 8
Dependent Claim
95 words
A fibrous bundle for use in textile material comprising a multiplicity of elongated synthetic polymeric superfine fibers of less than 0.7 denier, said bundle having a leg portion in which said superfine fibers are arranged closely adjacent one another in substantially parallel relationship, a plurality of the fibers in said leg portion being bound together with a cured organic silicone polymer, and said bundle having a free end portion integral with said leg portion in which at least some of the fibers of said plurality of fibers are free of any bonding to one another.
Claim 9
Dependent Claim
95 words
A fibrous bundle for use in textile material comprising a multiplicity of elongated synthetic polymeric superfine fibers of less than 0.7 denier, said bundle having a leg portion in which said superfine fibers are arranged closely adjacent one another in substantially parallel relationship, a plurality of the fibers in said leg portion being bound together with a cured organic silicone polymer, and said bundle having a free end portion integral with said leg portion in which at least some of the fibers of said plurality of fibers are free of any bonding to one another.
Claim 10
Dependent Claim
61 words
In a method of making a fibrous bundle for use in textile material from a fiber composed of a multiplicity of islands-in-a-sea superfine fibers of less than 0.7 denier, the steps which comprise encapsulating the fiber, dissolving out the sea component to produce encapsulated substantially free superfine fibers, binding said superfine fibers with a cured silicone polymer, and removing the encapsulation.
Claim 11
Dependent Claim
61 words
In a method of making a fibrous bundle for use in textile material from a fiber composed of a multiplicity of islands-in-a-sea superfine fibers of less than 0.7 denier, the steps which comprise encapsulating the fiber, dissolving out the sea component to produce encapsulated substantially free superfine fibers, binding said superfine fibers with a cured silicone polymer, and removing the encapsulation.
Claim 12
Dependent Claim
33 words
The method defined in claim 8 further including the step of removing cured silicone polymer from an end portion of said fibrous bundle while leaving said cured silicone polymer in another portion thereof.
Claim 13
Dependent Claim
22 words
The method defined in claim 8 further including the step of forming said fiber into a fabric prior to said encapsulation step.
Claim 14
Dependent Claim
22 words
The method defined in claim 10 further including the step of raising nap on said fiber subsequent to said fiber formation step.
