Abstract
Abstract A knitted fabric having a multi-layered structure made of non-hygroscopic fiber yarn, such as synthetic yarn, in which the inter-fiber space in a yarn composing a surface layer is smaller than that in a yarn composing a back layer. The size of the inter-fiber space can be controlled by varying the fiber fineness, knitted structure, and/or yarn type composing each of the layers. The fabric according to the present invention has good water-permeability and water-diffusibility and, therefore, is suitable for sportswear.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
139 words
A knitted fabric specially adapted for use in clothing which comprises a layered structure having at least a first, inner yarn layer and a second, outer yarn layer, wherein said first yarn layer is to be disposed facing a wearer's body, and said second yarn layer is to be disposed on the side further from the wearer's body; wherein each yarn layer is further comprised of a plurality of fibers, said fibers each being at least one denier and consisting essentially of non-hygroscopic fibers, wherein the inter-fiber spaces between neighboring individual non-hygroscopic fibers of the first yarn layer are larger than the interfiber spaces between the neighboring individual non-hygroscopic fibers of said second yarn layer, whereby perspiration in contact with said first yarn layer moves through said first yarn layer and into said second yarn layer by capillary action.
Claim 2
Dependent Claim
139 words
A knitted fabric specially adapted for use in clothing which comprises a layered structure having at least a first, inner yarn layer and a second, outer yarn layer, wherein said first yarn layer is to be disposed facing a wearer's body, and said second yarn layer is to be disposed on the side further from the wearer's body; wherein each yarn layer is further comprised of a plurality of fibers, said fibers each being at least one denier and consisting essentially of non-hygroscopic fibers, wherein the inter-fiber spaces between neighboring individual non-hygroscopic fibers of the first yarn layer are larger than the interfiber spaces between the neighboring individual non-hygroscopic fibers of said second yarn layer, whereby perspiration in contact with said first yarn layer moves through said first yarn layer and into said second yarn layer by capillary action.

Claim 7
Dependent Claim
14 words
A knitted fabric according to claim 1 wherein said fabric consists of non-hygroscopic fibers.
Claim 8
Dependent Claim
13 words
A knitted fabric according to claim 6 wherein said non-hygroscopic fibers are polyester.
Claim 9
Dependent Claim
60 words
A knitted fabric according to claim 1, wherein said first yarn layer comprises the same or different yarn as is found in said second yarn layer and the relative difference in size between the inter-fiber spaces of neighboring individual fibers of said first yarn layer and said second yarn layer is the result of the knit construction of said fabric.
Claim 10
Dependent Claim
46 words
A knitted fabric according to claim 1, wherein the layered structure is formed by a plaiting knit arrangement of at least two yarns so that there is a relative difference in interfiber space between the fiber group of one yarn and that of the other yarn.
Claim 11
Dependent Claim
28 words
A knitted fabric according to claim 1, wherein at least one layer is formed by using a tuck knit construction more frequently than that of the other layer.
Claim 12
Dependent Claim
20 words
A knitted fabric according to claim 1, wherein at least one layer is formed by using an inlaid yarn construction.
Claim 13
Dependent Claim
19 words
A knitted fabric according to claim 1, wherein the yarn forming one layer is knitted into the other layer.
Claim 14
Dependent Claim
27 words

Claim 16
Dependent Claim
63 words
A knitted fabric according to claim 1, wherein said first yarn layer comprises coarser fibers and said second yarn layer comprises finer fibers such that the relative difference in size between the inter-fiber spaces of neighboring individual fibers of said first yarn layer and said second yarn layer is the result of the inter-fiber spaces occurring in the yarn employed in said layers.
Claim 17
Dependent Claim
28 words
