[0029] The embodiments of the present application will be described in detail below with reference to the drawings. In the case of no conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0030] Please refer to Figures 1-8 The embodiment of the present application provides a kind of durable antibacterial natural regenerated fiber interwoven fabric, including base layer 1, transition layer 2, antibacterial layer 3 and protective layer 4, by the above combination, form natural regenerated fiber interwoven fabric.

[0031] The base layer 1 is made of warp yarns 8 and weft yarns 9, and the surface of the base layer 1 is provided with protrusions 10 and depressions 11, which form a continuous micro-convex and concave structure, increase the specific surface area, and facilitate the subsequent attachment of the antibacterial layer 3.

[0032] The transition layer 2 is arranged on the upper side of the base layer 1, and is woven from bamboo fibers 13, hemp fibers 14, and cotton fibers 15, which are natural regenerated materials and have excellent moisture absorption and sweat-wicking functions, further improving the comfort of the fabric.

[0033] The antibacterial layer 3 is arranged on the upper side of the transition layer 2, and contains nano-silver particles as an antibacterial agent. The antibacterial layer 3 is tightly attached to the base layer 1 and the transition layer 2 through cross-linking technology, preventing the antibacterial agent from falling off. The antibacterial layer 3 is locally thickened according to the fiber weaving pattern to form antibacterial points 12. The thickness of each antibacterial point 12 is 1.5-2 times the average thickness of the antibacterial layer 3, and the concentration of nano-silver particles in the antibacterial points 12 is 20%-30% higher than that in the surrounding areas. This allows the antibacterial agent to be concentrated in key areas, significantly enhancing the local antibacterial effect while reducing the total amount of antibacterial agent used.

[0034] The protective layer 4 is overlaid on the antibacterial layer 3 and is made of transparent and wear-resistant biodegradable material polylactic acid, ensuring that the entire fabric does not pollute the environment after being discarded.

[0035] Ventilation holes 6 are distributed on the base layer 1, the transition layer 2, the antibacterial layer 3, and the protective layer 4. The diameter of the ventilation holes 6 is 0.1-0.5 mm, and the edges of the ventilation holes 6 form micro-channels 7 made of gradient wetting materials. The inner side close to the ventilation holes 6 is hydrophilic, and the outer side away from the ventilation holes 6 is hydrophobic, forming a "capillary blood vessel" effect for directional transmission of liquid, which helps to quickly drain sweat and keep the skin dry.

[0036] The base layer 1, the transition layer 2, the antibacterial layer 3, and the protective layer 4 are locked on the four sides by high-strength stitching, and a layer of waterproof strip with a width of 2-3 mm and a thickness of 0.1-0.2 mm is overlaid on the outside of the stitching on the side edges 5. The waterproof strip is made of thermoplastic polyurethane material, which enhances the durability and waterproof performance of the fabric.

[0037] In conclusion, the working principle of the durable antibacterial natural regenerated fiber interwoven fabric is: selecting warp yarn 8 and weft yarn 9 to make cloth through a spinning process, and using mechanical polishing to manufacture micro concave-convex structures on the surface, placing the transition layer 2 above the base layer 1 to enhance the moisture absorption and perspiration capacity of the fabric, uniformly coating a solution containing nano silver particles on the transition layer 2, then making the antibacterial layer 3 firmly adhere to the transition layer 2 through cross-linking reaction, and thickening the antibacterial layer 3 according to the needs to form antibacterial points 12, applying a transparent wear-resistant protective film made of polylactic acid on the antibacterial layer 3, creating air holes 6 arranged in a specific mode on each layer of fabric by using laser drilling technology, and specially treating the hole edges to form an effect similar to "capillary blood vessels", reinforcing the edges of the fabric by high-strength stitching, and adding waterproof strips.

[0038] The preferred embodiments of the utility model are merely used for limiting the utility model, and the utility model can be changed and varied in various ways for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
