[0020] The layers are labeled as follows: 10 - sweat-absorbing layer, 20 - water-absorbing and retaining layer, 30 - breathable layer. Detailed Implementation

[0021] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0022] Figure 1 is a schematic diagram of the sweat-absorbing and cooling structure in an embodiment of the present invention;

[0023] As shown in Figure 1, the sweat-absorbing and cooling structure provided by the present invention includes a sweat-absorbing layer 10, a water-absorbing and storing layer 20, and a breathable layer 30. The water-absorbing and storing layer 20 is disposed between the sweat-absorbing layer 10 and the breathable layer 30. The sweat-absorbing layer 10 can absorb sweat from the surface of the outdoor person's skin, keeping the outdoor person's skin surface dry and comfortable. The water-absorbing and storing layer 20 can further absorb the sweat from the sweat-absorbing layer 10, and then evaporate it through the breathable layer 30. Through evaporation and heat absorption, the temperature of the outdoor person's skin surface is reduced, thereby cooling the outdoor person and reducing the risk of heatstroke and other dangerous situations.

[0024] The sweat-absorbing layer 10 includes at least one layer of absorbent fabric. The sweat-absorbing layer 10 adheres to the skin surface of outdoor personnel and can absorb sweat from the skin surface of outdoor personnel, keeping the skin and body of outdoor personnel dry, improving the comfort of outdoor personnel, and preventing sweat accumulation from affecting the wearing experience of outdoor personnel.

[0025] The absorbent water storage layer 20 includes at least one resin layer, but is not limited to using only resin materials. Other highly absorbent materials can also be selected. The absorbent water storage layer 20 is sponge-like, and its absorbency is greater than that of the sweat-absorbing layer 10. This allows it to further absorb and store the sweat absorbed by the sweat-absorbing layer 10, thereby ensuring that the sweat-absorbing layer 10 can continuously absorb sweat from the surface of the outdoor person's skin and keep the outdoor person's skin surface dry.

[0026] The breathable layer 30 includes at least one layer of breathable and water-permeable fabric. The breathable layer 30 allows sweat stored in the absorbent layer 20 to evaporate, effectively cooling outdoor personnel through heat absorption during evaporation and preventing heatstroke and other dangerous situations. The breathable layer 30 also protects the absorbent layer 20 from external damage. Furthermore, the breathable and water-permeable fabric used in the breathable layer 30 is ordinary, inexpensive, and easily cut and processed into various garment styles and colors, facilitating the customization of cooling clothing products according to customer needs.

[0027] Figure 2 is a schematic diagram of the structure of the water-absorbing and water-storing layer in an embodiment of the present invention.

[0028] As shown in Figure 2, the absorbent water-retaining layer 20 is sheet-like and evenly distributed between the sweat-absorbing layer 10 and the breathable layer 30. The sweat-absorbing layer 10, the absorbent water-retaining layer 20, and the breathable layer 30 are connected by stitching or bonding. The sheet-like absorbent water-retaining layer 20 is evenly distributed between the sweat-absorbing layer 10 and the breathable layer 30, and there are gaps between the sheet-like absorbent water-retaining layers 20. It is not directly connected, which can effectively prevent the accumulation of water in the absorbent water-retaining layer 20 and prevent sweat from dripping down, thus avoiding affecting the sweat absorption and heat dissipation effects.

[0029] Figure 3 is a schematic diagram of the process of sweat entering the sweat-absorbing and cooling structure in an embodiment of the present invention; Figure 4 is a schematic diagram of the process of sweat entering the sweat-absorbing and cooling structure in an embodiment of the present invention; Figure 5 is a schematic diagram of the process of sweat entering the sweat-absorbing and cooling structure in an embodiment of the present invention.

[0030] As shown in Figures 3, 4, and 5, when outdoor personnel wear the cooling clothing products made with the sweat-absorbing and cooling structure provided by this invention, the sweat on the surface of the outdoor personnel's skin is absorbed by the sweat-absorbing layer 10, keeping the outdoor personnel's skin dry and improving their comfort. This prevents sweat accumulation from affecting the outdoor personnel's wearing experience. The water-absorbing and storing layer 20 further absorbs and stores the sweat absorbed by the sweat-absorbing layer 10, thereby ensuring that the sweat-absorbing layer 10 can continuously absorb sweat from the surface of the outdoor personnel's skin, keeping the outdoor personnel's skin surface dry. The breathable layer 30 allows the sweat stored in the water-absorbing and storing layer 20 to evaporate, effectively cooling the outdoor personnel through evaporation heat absorption and reducing the risk of heatstroke and other dangerous situations.

[0031] Figure 6 is a schematic diagram of the water addition process in an embodiment of the present invention.

[0032] As shown in Figure 6, when outdoor personnel wear cooling clothing products made of the sweat-absorbing and cooling structure provided by the present invention, water can be added to the surface of the breathable layer 30 in advance, so that the water-absorbing and water-storing layer 20 can absorb and store a certain amount of water in advance, thereby directly cooling the outdoor personnel.

[0033] Surface temperature tests were conducted on the sweat-absorbing and cooling structure provided by this invention and ordinary clothing at different temperatures, and the results are shown in Table 1 below:

[0034] Table 1: Cooling Data Table

[0035] The test results show that the sweat-absorbing and cooling structure provided by the present invention can effectively cool down the body, thereby effectively preventing outdoor personnel from suffering from heatstroke and other dangerous situations. Moreover, the higher the ambient temperature, the greater the temperature difference that the sweat-absorbing and cooling structure provided by the present invention can reduce, and the better the effect, thereby further ensuring that outdoor personnel are protected from heatstroke and other dangerous situations.

[0036] The role and effect of the embodiments

[0037] The sweat-absorbing and cooling structure provided by this invention includes a sweat-absorbing layer 10, a water-absorbing and storing layer 20, and a breathable layer 30. The water-absorbing and storing layer 20 is disposed between the sweat-absorbing layer 10 and the breathable layer 30. The sweat-absorbing layer 10 can absorb sweat from the skin surface of outdoor personnel, keeping their skin surface dry and comfortable. The water-absorbing and storing layer 20 can further absorb the sweat from the sweat-absorbing layer 10, which then evaporates through the breathable layer 30. Through evaporation and heat absorption, the temperature of the skin surface of outdoor personnel is reduced, thereby cooling them down and reducing the risk of heatstroke and other dangerous situations. The sweat-absorbing and cooling structure provided by this invention has a good sweat-absorbing and cooling effect, ensuring the safety and comfort of outdoor personnel when working outdoors.
