Abstract

A multi-ply knit fabric containing a first knit ply containing a plurality of first and second yarns, where the first knit ply forms the upper surface of the fabric. The first knit ply contains a first knit pattern having a repeating pattern of first areas and second areas, where within the first areas the first and second yarns are knitted together and within the second areas the first yarns are knitted together and the second yarns float across approximately the entire second areas. The first areas and second areas have at least one dimension within the plane of the first ply knit of at least about 0.5 mm. The fabric also contains a second knit ply forming the lower surface of the fabric and a plurality of stuffer yarns located between the first and second knit ply.

First claim

What is claimed is:

1 . A multi-ply knit fabric having a first surface and a second surface and a first direction and a second direction, wherein the fabric comprises:
a first knit ply comprising a plurality of first yarns and a plurality of second yarns, wherein the first knit ply forms the first surface of the fabric, wherein the first knit ply comprises a first knit pattern having a repeating pattern of first areas and second areas, wherein within the first areas the first and second yarns are knitted together and within the second areas the first yarns are knitted together and the second yarns float across approximately the entire second areas, wherein the first areas and second areas have at least one dimension within a plane of the first ply knit of at least 2 mm, wherein the first knit ply has a first knit ply surface area and the first areas have a first area surface area, wherein the first area surface area is between 40% and 60% of the first knit ply surface area, and wherein floats of the second yarns are located on a surface of the first ply facing the second ply; a second knit ply comprising a plurality of third yarns, wherein the second knit ply forms the second surface of the fabric; and, a plurality of stuffer yarns located between the first knit ply and the second knit ply; wherein the first ply and the second ply are integrated through combined portions formed by interlacing the third yarns of the second ply among the first or second yarns of the first knit ply, wherein the combined portions are located in parallel lines in the second direction of the multi-ply knit fabric between the patterns of first and second areas forming pocket channels, and wherein the stuffer yarns are located in the pocket channels between the first knit ply and the second knit ply and are generally parallel to the combined portions.

2 . The multi-ply knit fabric of claim 1 , wherein the first areas have approximately twice the number of knit stitches per unit area than that of the second areas.

3 . The multi-ply knit fabric of claim 1 , wherein the first and second areas of the first ply having different amounts of hydrophobicity.

4 . The multi-ply knit fabric of claim 1 , wherein the first knit pattern comprises a repeating rectangular grid of first and second areas.

5 . The multi-ply knit fabric of claim 1 , wherein an air permeability of the second areas is greater than an air permeability of the first areas, wherein the first areas have an openness and the second areas have an openness, and wherein the openness of the second area is greater than the openness of the first areas.

6 . The multi-ply knit fabric of claim 1 , wherein the multi-ply knit fabric comprises at least 98% by weight continuous multifilament polyester yarns.
