Abstract

Provided is a knit fabric which does not cause feelings of clamminess, feels very cool to the touch and is comfortable, and limits feelings of stickiness and post-sweat chill through rapid drying of sweat, and at the same time is capable of further improving texture. The garment comprises a multilayer-structure circular-knit fabric made of a single circular knit with a layered structure of at least two layers, and the surface that contacts the skin is the needle-loop side of the circular-knit fabric. The circular-knit fabric has portions in which long cellulose fibers and hydrophobic fibers are knit together to form the same knit loops. The garment contains 10-50 weight % of the long cellulose fibers. The exposure rate of the long cellulose fibers in the region from the surface of the side that contacts the skin to 0.13 mm into the interior of the circular-knit fabric is at least 30%.

First claim

The invention claimed is:

1. A garment comprising a multilayer-structure circular knit fabric composed of a single circular knit having a layer structure of at least two layers, and having a skin-contacting surface which is a needle-loop side of the circular-knit fabric, wherein the circular-knit fabric has a portion in which long cellulose fibers and hydrophobic fibers are knitted together to form identical knit loops, the circular-knit fabric contains 10 to 50 wt % of the long cellulose fibers, an exposure rate of the long cellulose fibers in a region from the skin-contacting surface within 0.13 mm toward an interior of the circular-knit fabric is at least 30%, a tactile coolness of the circular-knit fabric is 130 to 200 W/m 2 ·° C., and the time at which a moisture content of the circular-knit fabric becomes 10% after 0.3 cc of water is dripped thereon is not greater than 50 minutes, and a difference in height irregularities of the skin-contacting surface of the multilayer-structure circular knit fabric is not greater than 0.10 mm.

2. The garment according to claim 1 , wherein a single-fiber fineness of the long cellulose fibers is 0.1 to 7.0 dtex.

3. The garment according to claim 1 , wherein an average coefficient of friction of the skin-contacting surface of the circular-knit fabric is not greater than 0.45, and an average deviation of the average coefficient of friction is not greater than 0.0090.

4. The garment according to claim 1 , wherein the multilayer-structure circular knit fabric has a plain knit structure.

5. The garment according to claim 1 , wherein a fiber length ratio of the long cellulose fibers to the hydrophobic fibers is 1.01 to 1.20.

6. The garment according to claim 1 , wherein a single-fiber fineness ratio of the long cellulose fibers to the hydrophobic fibers is 0.3 to 1.0.

7. The garment according to claim 1 , wherein a total fineness ratio of the long cellulose fibers to the hydrophobic fibers is 1.0 to 3.0.

8. The garment according to claim 1 , wherein the multilayer-structure circular knit fabric has undergone a water absorption treatment.

9. The garment according to claim 1 , wherein the multilayer-structure circular knit fabric further includes elastic fibers, and the elastic fibers are arranged in an intermediate layer.

10. The garment according to claim 1 , wherein the multilayer-structure circular knit fabric is composed of a structure in which identical loops of the long cellulose fibers and the hydrophobic fibers are formed, and a structure in which only loops of the hydrophobic fibers are formed.
