## Abstract

It is provided a fabric comprises a yarn that is bi-component yarn air texturized with a mechanical stretched synthetic polymer yarn and a high moisture regain yarn with greater fiber weight per filament than the bi-component yarn. The weft yarns are interwoven with the warp yarns such that the woven fabric defines a face side and a back side opposite to the face side. The high moisture regain yarn is inserted such that it generates plurality of long high moisture regain yarn floats such that a majority of the long high moisture regain yarn floats are on the back side of the woven fabric. The high moisture regain yarn can be inserted in weft or in warp direction or can alternate or at different intervals such that the longer floats are on the backside for more exposure to the skin.

## Claims

### Claim 1

A woven fabric comprising a face side and a back side, said woven fabric comprising:
warp yarns interwoven with weft yarns;
the warp yarns including;
a warp combination yarn comprising a bi-component core yarn and a texturized multifilament feed yarn texturized with or twisted with the bi-component core yarn;
the weft yarns including:
a first weft multifilament yarn; and
a second weft multifilament yarn comprising regenerated cellulosic filaments or synthetic polymer filaments, wherein a denier per filament of the second weft multifilament yarn is greater than a denier per filament of the warp combination yarn;
wherein the woven fabric includes weft insertions of the first weft yarn and weft insertions of the second weft yarn, the weft insertions of the second weft yarn form a plurality of weft yarn floats every second, third, fourth, fifth, or sixth weft insertion;
wherein a majority of the weft yarn floats are on the back side of the woven fabric, the weft yarn floats on the back side of the woven fabric act to remove moisture from the back side of the woven fabric and out of the face side of the woven fabric; and
wherein the face side of the woven fabric is configured to face away from a wearer and the back side of the woven fabric is configured to be closer to the wearer.

### Claim 2 (depends on 1)

The woven fabric of claim 1, wherein a polymer of the bi-component core yarn of the warp combination yarn comprises a polyester, a polyacrylic, a Polytrimethylene terephthalate, a nylon, a polypropylene, an acrylic or any blend or combination thereof.

The woven fabric of claim 9, wherein the woven fabric comprises insertions of the second weft multifilament yarn in every other insertion.

### Claim 11 (depends on 1)

The woven fabric of claim 1, wherein 60% of the plurality of weft yarn floats are on the back side of the woven fabric and 40% of the plurality of weft yarn floats are on the face side of the woven fabric.

### Claim 12 (depends on 1)

The woven fabric of claim 1, wherein 90% of the plurality of weft yarn floats are on the back side of the woven fabric and 10% of the plurality of weft yarn floats are on the face side of the woven fabric.

### Claim 13 (depends on 1)

The woven fabric of claim 1, wherein the warp combination yarn is dyed; or
wherein the woven fabric is dyed.

### Claim 14 (depends on 1)
