[0026] Preferably, the cross-section of the fully matte special-section nylon filament is a cross-section, a Y-section or an ∞-section nylon filament. By designing the cross-section of the first yarn as a special-section, the specific surface area of ​​the first yarn is increased compared with that of the conventional round yarn. Therefore, the contact area between the first yarn and the air is increased, which is more conducive to rapid evaporation of moisture, reduces the sweat remaining on the skin surface, and keeps the skin dry.

[0027] Furthermore, the inner side of the fabric body formed by weaving the first yarn into a loop is cross-hollow and has micropores on the surface, which further improves the breathability. Once you sweat profusely during activities, the clothing will not stick to the skin and produce a cold and wet feeling.

[0028] In the utility model, the first yarn and the second yarn are woven together so that the inner side surface of the fabric body forms a woven surface in which the first yarn covers the second yarn. Since the first yarn is exposed on the inner side and the first yarn has a cool feeling, the woven surface is a cool surface; the high temperature resistant second yarn is exposed on the outer side, and its sun protection effect is better.

[0029] Preferably, the fabric body is woven from a 1×1 warp plain weave woven from a first yarn and a 1×1 warp plain weave woven from a second yarn, the first yarn and the second yarn run in different directions and both form a closed loop structure, that is, the extension lines of the coil base cross each other.

[0030] The first yarn and the second yarn are alternately laid on two adjacent needles to form loops and are strung together to form a warp plain structure. The first yarn and the second yarn are woven by two combing bars GB1 and GB2 respectively. The laying yarn numbers of the 1×1 warp plain structure woven by the first yarn are 1-0 / 1-2 / / , and the laying yarn numbers of the 1×1 warp plain structure woven by the second yarn are 1-2 / 1-0 / / .

[0031] Preferably, the transverse coil density of the fabric body is 27 / cm, the longitudinal coil density of the fabric body is 49c / cm, the width of the fabric body is 150-155cm, and the gram weight of the fabric body is 150-160gsm.

[0032] The utility model also proposes a sun-proof clothing, which includes the above-mentioned fabric body. When the sun-proof clothing is made of the fabric body, it has good air permeability when worn on the body, is not easy to make people feel stuffy, and can also prevent ultraviolet rays from penetrating, ensuring a good sun protection effect, which is beneficial for the wearer to engage in long-term outdoor activities.
