Abstract

Provided is a multilayer-structure circular knit fabric that has excellent cool touch sensation and moisture absorbability, has improved moisture dispersibility, is quick drying to avoid the feeling of dampness, is very comfortable with high cool touch sensation, can reduce stickiness and a cold feeling after sweating by causing the sweat to dry quickly, and has a pleasant texture. The multilayer-structure circular knit fabric is formed of a single circular knit having a layer structure with two or more layers, and has a section where a cellulose-based continuous fiber and a hydrophobic fiber form the same knit loop.

First claim

2. The multilayer structure circular knit fabric according to claim 1 , wherein the single yarn fineness of the cellulose-based continuous fiber is 0.1 dtex to 7.0 dtex.

3. The multilayer structure circular knit fabric according to claim 2 , wherein the mean coefficient of friction of the surface in which the cellulose-based continuous fiber is arranged is 0.90 or less and the mean deviation of the coefficient of friction is 0.0070 or less.

4. The multilayer structure circular knit fabric according to claim 1 , at least containing a jersey knit structure.

5. The multilayer structure circular knit fabric according to claim 1 , wherein the yarn length ratio between the cellulose-based continuous fiber and the hydrophobic fiber is 1.01 to 1.20.

6. The multilayer structure circular knit fabric according to claim 1 , wherein the single yarn fineness ratio between the cellulose-based continuous fiber and the hydrophobic fiber is 0.3 to 1.0.

7. The multilayer structure circular knit fabric according to claim 1 , wherein the fineness ratio between the cellulose-based continuous fiber and the hydrophobic fiber is 1.0 to 3.0.

8. The multilayer structure circular knit fabric according to claim 1 , which is subjected to moisture absorbing processing.

9. The multilayer structure circular knit fabric according to claim 1 , wherein the difference in surface unevenness height of the layer on the side of the skin is 0.13 mm to 0.60 mm.

10. The multilayer structure circular knit fabric according to claim 1 , wherein the circular knit fabric further contains an elastic fiber and the elastic fiber is arranged in an intermediate layer.

11. The multilayer structure circular knit fabric according to claim 1 , wherein the mean coefficient of friction of the surface in which the cellulose-based continuous fiber is arranged is 0.90 or less and the mean deviation of the coefficient of friction is 0.0070 or less.

12. The multilayer structure circular knit fabric according to claim 2 , wherein the yarn length ratio between the cellulose-based continuous fiber and the hydrophobic fiber is 1.01 to 1.20.
