In particular, when the fiber has a single filament fineness of 1.5 dtex or less (more preferably 1.0 dtex or less, and still more preferably 0.0001 to 1.0 dtex), excellent water absorption and texture are obtained, which is preferable. It is more preferable that the single fiber fineness is smaller than that of the water-repellent fiber. Ultra-fine fibers with a single filament fiber diameter of 1 μm or less called nanofibers, as described in International Publication No. 2005/095686 pamphlet, may also be used. Further, a multifilament having 10 or more filaments is preferable because it provides more excellent water absorption and texture. At that time, the total fineness of the multifilament is preferably in the range of 20 to 200 dtex (more preferably 20 to 150 dtex).

When it is arranged, it is easy to achieve both the contradictory performances of air permeability and ultraviolet shielding properties, which is preferable. In this case, if a water-repellent fiber is used as the large fineness yarn and a non-water-repellent fiber is used as the fine fineness yarn, the sweat absorbency is maintained and the comfortability is improved because the sweat absorption property is maintained. Conversely, if a non-water-repellent fiber is used as the large fineness yarn and a water-repellent fiber is used as the fine fineness yarn, an effect of preventing perspiration can be obtained.

In addition, if the weave density is sparse and the large fineness yarn (the total fineness is large) is arranged on the skin side, and the weave density is dense and the fine fineness yarn (the total fineness is small) is arranged on the outside air side, ventilation It becomes easy to achieve both the contradictory performances of properties and UV shielding properties. In this case, if a water-repellent fiber is used as the large fineness yarn and a non-water-repellent fiber is used as the fine fineness yarn, the sweat absorbency is maintained and the comfortability is improved because the sweat absorption property is maintained. Conversely, if a non-water-repellent fiber is used as the large fineness yarn and a water-repellent fiber is used as the fine fineness yarn, an effect of preventing perspiration can be obtained.
