Abstract
Abstract A woven fabric comprising glass fibers cushioned from each other by organic fibers in the warp direction, the sinuosity of the glass fibers being less than or equal to the sinuosity of the organic fibers for a given length of woven fabric, and organic fibers in the fill direction has an extremely low degree of stretchability in the warp direction and exhibits high strength under tension in the warp direction. Abrasive belts comprising the woven fabric coated with an adhesive containing abrasive particles exhibit close to zero elongation, have long lives and can be repeatedly used for debarking logs.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
56 words
A woven fabric comprising glass fibers which are cushioned from each other along their length by organic fibers, the sinuosity of the glass fibers being less than or equal to the sinuosity of the organic fibers in a given length of the woven fabric, and organic fibers in the direction generally transverse to said glass fibers.
Claim 2
Dependent Claim
56 words
A woven fabric comprising glass fibers which are cushioned from each other along their length by organic fibers, the sinuosity of the glass fibers being less than or equal to the sinuosity of the organic fibers in a given length of the woven fabric, and organic fibers in the direction generally transverse to said glass fibers.
Claim 3
Dependent Claim
41 words
A woven fabric as claimed in claim 1 wherein said organic fibers which cushion the glass fibers are selected from the group consisting of cotton fibers, polyester fibers, polyester-cotton blend fibers, nylon fibers, wool, acrylic fibers, acetate fibers, and mixtures thereof.
Claim 4
Dependent Claim
15 words
A woven fabric as claimed in claim 1 wherein the organic fibers are textured yarns.
Claim 5
Dependent Claim
15 words
A woven fabric as claimed in claim 1 wherein the organic fibers are spun yarns.
Claim 6
Dependent Claim
44 words
A woven fabric as claimed in claim 1 wherein said organic fibers which are generally transverse to the glass fibers are selected from the group consisting of cotton fibers, polyester fibers, polyester-cotton blend fibers, nylon fibers, wool, acrylic fibers, acetate fibers and mixtures thereof.
Claim 7
Dependent Claim
35 words
A woven fabric as claimed in claim 1 wherein the alternating organic fibers and glass fibers are warp yarns, and said organic fibers in the direction generally transverse to the glass fibers are filling yarns.
Claim 8
Dependent Claim
32 words
A woven fabric as claimed in claim 6 wherein the organic fill yarns are 100% spun polyester yarns and the organic warp yarns are spun yarns of 50% cotton and 50% polyester.
Claim 9
Dependent Claim
26 words
A woven fabric as claimed in claim 1 wherein a glass fiber is substituted for every third, sixth, or twenty-fourth organic fiber in said transverse direction.
Claim 10
Dependent Claim
17 words
A woven fabric as claimed in claim 1 wherein said glass fibers are coated with a resin.
Claim 11
Dependent Claim
20 words
A woven fabric as claimed in claim 9 wherein said resin is an acrylic latex resin or a resorcinol-formaldehyde resin.
Claim 12
Dependent Claim
31 words
An abrasive comprising the woven fabric of claim 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 coated on at least one surface with an adhesive containing abrasive particles.
Claim 13
Dependent Claim
16 words
An abrasive as claimed in claim 11 which is in the form of an endless belt.
Claim 14
Dependent Claim
53 words
An abrasive as claimed in claim 11 wherein said adhesive is selected from the group consisting of epoxy resins, acrylic resins, polyurethane resins, and phenolic resins and mixtures thereof, and said abrasive particles are selected from the group consisting of aluminum oxide, silicon carbide, talc, cerium oxide, garnet, flint, emery and mixtures thereof.
