[0015] Preferably, the guide groove is opened transversely along the curved extensions on both sides of the anti-seepage layer, and the sides of the guide groove are opened to the lower side of the adsorption layer.

[0016] A processing technology for ultra-fine filament composite fabric comprises the following steps: S1. Ultrafine filament polyester-cotton fiber, polyester fiber and nylon fiber are blended by using a blending textile machine to weave into a fabric base, and then a PA adhesive layer is coated on the upper surface of the fabric base. At this time, a lower docking layer is placed on the PA adhesive layer, so that the lower docking layer is bonded to the fabric base through the PA adhesive layer, and the contact area between the lower docking layer and the PA adhesive layer is further increased through the docking protrusion, thereby improving the adhesion effect between the PA adhesive layer and the lower docking layer; S2, placing the metal mesh layer on the upper surface of the lower docking layer for bonding treatment, sewing the lower connecting rope to the left side of the upper surface of the lower docking layer, after the metal mesh layer is placed, clamping the lower connecting rope to the inner side of the docking buckle set on the left side of the metal mesh layer, and at the same time, bonding the wear-resistant layer to the upper surface of the metal mesh layer, and clamping the upper connecting rope sewn on the lower surface of the wear-resistant layer to the inner side of the docking buckle set on the right side of the metal mesh layer, and fixing the metal mesh layer by the clamping action between the upper connecting rope and the lower connecting rope on the docking buckle set on the side of the metal mesh layer; S3, pasting the lower surface of the fabric base layer to the upper surface of the hydrophobic layer, and pasting the lower surface of the hydrophobic layer to the upper surface of the anti-seepage layer.

At the same time, the water body can be blocked by the anti-seepage layer to reduce water infiltration. The anti-seepage layer is provided with a diversion groove to divert the blocked water body. At this time, the water body can be adsorbed by the adsorption layer arranged on the side of the anti-seepage layer to avoid water outflow caused by too much water in the anti-seepage layer.

[0021] A hole is arranged at the center of the metal mesh layer, and the hole allows the metal mesh layer to still have a breathable and hydrophobic area for the fabric when it is bonded to the wear-resistant layer and the lower docking layer, thereby enhancing the breathability of the composite fabric. The metal mesh layer is made of a memory alloy, which will deform or restore to its pre-deformation state at room temperature or high temperature. When the composite fabric is at room temperature or in a normal state under a special environment and restores to its initial state, the composite fabric will present a certain curvature, thereby changing the fit between the fabric and the skin, and further enhancing the thermal insulation or breathability of the fabric.

[0026] The wear-resistant layer 6 is twisted by high-strength and high-tenacity fibers, such as polyester fibers and nylon fibers, so as to effectively resist external friction and wear. At the same time, the wear-resistant protrusions 7 are formed on the outside of the wear-resistant layer 6 through a mechanical protrusion process (yarn or cotton thread is mixed into a tough embossing roller and then rolled together with the fabric to form raised lines and patterns on the surface of the fabric). At this time, the protrusion structure is formed to increase the wear resistance and decorativeness of the fabric.

[0027] The metal mesh layer 8 is made of memory alloy material. The metal mesh layer 8 is placed on the upper surface of the lower docking layer 13 for bonding treatment. The lower connecting rope 12 is sewn to the left side of the upper surface of the lower docking layer 13. After the metal mesh layer 8 is placed, the lower connecting rope 12 is clamped and placed on the inner side of the docking buckle 17 set on the left side of the metal mesh layer 8. At the same time, the wear-resistant layer 6 is bonded and set on the upper surface of the metal mesh layer 8.

Thereby reducing the phenomenon of loosening between the metal mesh layer 8 and the fabric. When the wear-resistant layer 6 is bonded to the upper surface of the metal mesh layer 8, a hole is provided at the center of the metal mesh layer 8.

The metal mesh layer 8 is made of a memory alloy, which will deform or restore to its pre-deformation state at room temperature or high temperature. When the composite fabric is in a normal state at room temperature or under a special environment and restores to its initial state, the composite fabric will present a certain curvature, thereby changing the fit between the fabric and the skin, and further enhancing the thermal insulation or breathability of the fabric.

The fixed base layer is a lower docking layer 13, and the fixed base layer is composed of textile materials such as cotton, polyester, nylon, or new materials such as non-woven fabrics and films. The composite base layer is laminated by a laminating device, and the laminated fixed base layer is sent to a drying device for drying to form a lower docking layer 13. At this time, the lower docking layer 13 is placed above the PA adhesive layer 10, so that the lower docking layer 13 is bonded to the fabric base layer 1 through the PA adhesive layer 10, and a docking protrusion 14 is provided on the lower surface of the lower docking layer 13. At this time, the docking protrusion 14 will form a docking groove 15 on the PA adhesive layer 10, and the contact area between the lower docking layer 13 and the PA adhesive layer 10 is further increased by the docking protrusion 14, thereby improving the adhesion effect between the PA adhesive layer 10 and the lower docking layer 13.

[0031] The lower surface of the fabric base layer 1 is adhered to the upper surface of the hydrophobic layer 2, and the lower surface of the hydrophobic layer 2 is adhered to the upper surface of the impermeable layer 4. After the impermeable layer 4 is adhered, the excess part of the side of the impermeable layer 4 is bent upward, so that the side of the impermeable layer 4 and the side of the upper surface of the wear-resistant layer 6 are adhered to each other.
