Abstract
Abstract A novel woven fabric of triple-weft weave in accordance with this invention comprises a floating first weft and a floating third weft each comprising filamentary or spun yarns consisting mainly of extra fine fibers or filaments having extra fine denier. It further comprises a second weft of heavier denier woven between said first and third wefts and a warp of relatively heavy denier. The fabric of this invention has excellent characteristics such as good crease resistance, permanent pleatability, excellent resiliency, soft touch on both front and back fabric surfaces, usefulness to an apparel without lining and reversible high quality.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
134 words
A woven fabric comprising a warp and at least three separate wefts woven with said warp, at least two of said wefts being floating wefts each comprising a yarn consisting mainly of extra-fine fibers or filaments having monofilament deniers of less than about 0.7, and another of said wefts comprising filamentary or spun yarn comprising mainly fibers or filaments of about 5-15 denier, and said warp comprising filamentary or spun yarn comprising mainly fibers or filaments of about 5-15 denier, wherein a greater portion of one of said floating wefts is exposed on one surface of said fabric than are the other wefts on said surface and wherein a greater portion of another said floating weft is exposed on the other surface of said fabric than are the other wefts on said other surface.
Claim 2
Dependent Claim
134 words
A woven fabric comprising a warp and at least three separate wefts woven with said warp, at least two of said wefts being floating wefts each comprising a yarn consisting mainly of extra-fine fibers or filaments having monofilament deniers of less than about 0.7, and another of said wefts comprising filamentary or spun yarn comprising mainly fibers or filaments of about 5-15 denier, and said warp comprising filamentary or spun yarn comprising mainly fibers or filaments of about 5-15 denier, wherein a greater portion of one of said floating wefts is exposed on one surface of said fabric than are the other wefts on said surface and wherein a greater portion of another said floating weft is exposed on the other surface of said fabric than are the other wefts on said other surface.
Claim 3
Dependent Claim
17 words
The woven fabric defined in claim 1, wherein at least one of said floating wefts is raised.
Claim 4
Dependent Claim
30 words
The woven fabric defined in claim 1, wherein said floating wefts are composed of filamentary or spun yarn consisting mainly of extra-fine fibers or filaments having deniers of about 0.03-0.25.
Claim 5
Dependent Claim
24 words
The woven fabric defined in claim 1, wherein the monofilament deniers and the total deniers of both said floating wefts are substantially the same.
Claim 6
Dependent Claim
30 words
The woven fabric defined in claim 1, wherein the fabric is reversible and wherein the numbers of the floating wefts on opposed surfaces of the fabric are about the same.
Claim 7
Dependent Claim
21 words
The woven fabric defined in claim 1, wherein the number of warp yarns skipped by said floating wefts is about 2-12.
Claim 8
Dependent Claim
21 words
The woven fabric defined in claim 6, wherein the number of warp yarns skipped by said floating wefts is about 3-8.
Claim 9
Dependent Claim
25 words
The woven fabric defined in claim 1, wherein said warp and substantially all of said floating wefts are composed essentially of polyester fibers or filaments.
Claim 10
Dependent Claim
21 words
The woven fabric defined in claim 1, wherein said warp consists of fibers or filaments capable of developing contraction or crimp.
Claim 11
Dependent Claim
32 words
The woven fabric defined in claim 1, wherein the total denier of each said floating weft is greater than the total denier of said weft which has a denier of about 1-20.
Claim 12
Dependent Claim
48 words
The woven fabric defined in claim 1, wherein said floating wefts are located predominantly along the surfaces of the fabric and wherein the other weft is located predominantly in the inner portion of the fabric, and at least partially concealed by at least one of said floating wefts.
Claim 13
Dependent Claim
