[0025] Example

[0026] refer to Figures 1 to 4A composite fabric with waterproof, antistatic and breathable functions includes a fabric body. The fabric body includes a hydrophobic knitted layer 1, an antibacterial hydrophilic layer 2, an antistatic knitted layer 3 and a waterproof and breathable layer 4 bonded from bottom to top by hot melt adhesive. A plurality of perforations 11 are provided on the hydrophobic knitted layer 1. A water absorbing component extending into the middle of the perforations 11 is provided on the lower surface of the antibacterial hydrophilic layer 2. The hydrophobic knitted layer 1 is formed by interweaving the warp and weft of polypropylene fiber yarn and nylon fiber yarn. This structure is adopted to utilize the difference in moisture absorption performance between the hydrophobic knitted layer 1 and the antibacterial hydrophilic layer 2, so that moisture is transferred unidirectionally from the inside to the outside to keep the inside of the hydrophobic knitted layer 1 dry; the hydrophobic knitted layer 1 is woven from polypropylene fiber yarn and nylon fiber yarn, which ensure that the fabric body will not stick to the body when in direct contact with the body, and under the setting of the antibacterial hydrophilic layer 2, the sweat flowing out of the body surface is absorbed, thereby ensuring the dryness of the body surface; by opening a plurality of perforations 11 on the hydrophobic knitted layer 1 and providing a water-absorbing component extending into the perforations 11 on the antibacterial hydrophilic layer 2, when the hydrophobic knitted layer 1 contacts the sweat of human skin, more sweat can enter the perforations 11, so that the sweat can be more easily absorbed by the water-absorbing component and introduced into the antibacterial hydrophilic layer 2, thereby achieving the effect of rapid sweat absorption and moisture conduction.

[0027] The water absorbing component includes a first water absorbing component 6 and a second water absorbing component 5 which are equally spaced along the antibacterial hydrophilic layer, and a certain distance is left between the left and right sides of the water absorbing component and the perforation 11. With this structure, the purpose of rapid absorption can be achieved, and the dryness of the skin can be ensured.

[0028] The first water-absorbing member is a water-absorbing sheet 6, which is fixed on the lower surface of the antibacterial hydrophilic layer 2 by hot pressing and laminating. With this structure, the water-absorbing sheet 6 is made of porous silica gel, and its porous structure has good water absorption, which can quickly absorb and transport sweat on the skin to the antibacterial hydrophilic layer 2, and then discharge it to the outside of the fabric body, so as to keep the inside of the fabric dry at all times.

[0029] The second absorbent member 5 is woven by warp yarn 51 and weft yarn 52, wherein the warp yarn 51 is twisted by viscose fiber and the weft yarn 52 is twisted by acetate fiber; a plurality of inner grooves are provided on the lower surface of the absorbent member. With this structure, the hydrophilic properties of acetate fiber and viscose fiber are combined to greatly improve the moisture absorption, breathability and wearing comfort of the fabric; in addition, a plurality of inner grooves are provided on the lower surface of the absorbent member to increase the storage space for sweat, facilitate the absorption of the absorbent member and the antibacterial hydrophilic layer 2, and ensure dryness.

[0030] The antibacterial hydrophilic layer 2 is formed by interweaving the antibacterial fiber yarn and the composite yarn in warp and weft, the antibacterial fiber yarn is composed of capron copper ion fiber and nylon fiber, the composite yarn includes a core yarn 71, and an outer yarn 72 wound around the outside of the core yarn 71, the core yarn 71 is twisted from bamboo charcoal fiber, and the outer yarn 72 is twisted from cotton and linen fiber. With this structure, the antibacterial properties of the capron copper ion fiber and the bamboo charcoal fiber are combined to greatly improve the antibacterial properties of the woven fabric; the nylon fiber has the characteristics of strong water absorption and high strength, achieving the effect of moisture absorption and perspiration; the cotton and linen fiber has good moisture absorption and antistatic properties, which can further enhance the moisture absorption and perspiration and antistatic properties of the woven fabric.

[0031] The antistatic knitted layer 3 is formed by interweaving the warp and weft of the flax fiber flame retardant yarn and the polyimide fiber yarn. With this structure, the flame retardancy of the fabric can be greatly improved through the combination of the flame retardant properties of the flax fiber flame retardant yarn and the polyimide fiber yarn.

[0032] The waterproof and breathable layer 4 is set as a water-based acrylic film layer. With this structure, the water-based acrylic film layer can pass water vapor molecules in a single molecular state, but cannot pass water, playing a waterproof and breathable role, so that the woven fabric has better waterproof and breathable performance.

[0033] When in use, after the fabric body is cut and made into underwear, the hydrophobic knitted layer 1 is used as a body contact layer to contact the body. When sweating occurs on the body surface, the difference in moisture absorption performance between the hydrophobic knitted layer 1 and the antibacterial hydrophilic layer 2 is utilized to allow moisture to be transferred unidirectionally from the inside to the outside, so as to keep the inside of the hydrophobic knitted layer 1 dry. By providing a plurality of perforations 11 on the hydrophobic knitted layer 1 and providing a water-absorbing component extending into the perforations 11 on the antibacterial hydrophilic layer 2, when the hydrophobic knitted layer 1 contacts the sweat of the human skin, more sweat can enter the perforations 11, making it easier for the sweat to be absorbed by the water-absorbing component and introduced into the antibacterial hydrophilic layer 2, and then dissipated outward through the waterproof and breathable layer 4. In the process, the bacteria that are about to grow are sterilized by the capron copper ion fiber and bamboo charcoal fiber in the antibacterial hydrophilic layer 2.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
