After the metal mesh layer is placed, the lower connecting rope is clamped and placed inside the docking buckle provided on the left side of the metal mesh layer. At the same time, the wear-resistant layer is adhesively provided on the upper surface of the metal mesh layer. At the same time, an upper connecting rope is sewn on the side of the lower surface of the wear-resistant layer, and the upper connecting rope is clamped and placed inside the docking buckle provided on the right side of the metal mesh layer.

[0024] The fabric fabric base layer can be hydrophobic-treated through the hydrophobic holes opened on the hydrophobic layer. At the same time, the water body can be blocked by the anti-seepage layer to reduce the seepage of water. The anti-seepage layer is provided with diversion grooves to divert the blocked water body. At this time, the water body can be adsorbed by the adsorption layer provided on the side of the anti-seepage layer, avoiding water seepage caused by too much water body received in the anti-seepage layer. At the same time, the adsorption layer adsorbs and aggregates the water body in one place, and the user can separately treat the water body at the adsorption layer without performing a large-scale water treatment on the entire composite fabric.

[0025] The upper surface of the wear-resistant layer is provided with wear-resistant protrusions, and the wear-resistant performance of the overall wear-resistant layer can be enhanced through the wear-resistant protrusions, thereby further enhancing the practicality of the fabric.

[0026] A hole is provided at the center of the metal mesh layer. The hole enables the metal mesh layer to still have parts for the fabric to breathe and drain water when it is bonded to the wear-resistant layer and the lower docking layer, thereby enhancing the air permeability of the composite fabric. The metal mesh layer is made of shape memory alloy material, which will deform or return to its state before deformation at normal temperature or high temperature. When the composite fabric returns to its initial state at normal temperature or in a normal state in a special environment, it will cause the composite fabric to present a certain arc, thereby changing the fitting state between the fabric and the skin and further enhancing the heat preservation or air permeability state of the fabric.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1: As Figure 1 、 Figures 5 - 9For the technical solution shown, the present invention provides the following technical solution: an ultra-thin long filament composite fabric and its processing technology, which discloses a docking buckle 17, an upper connecting rope 11 and a lower connecting rope 12. Through the mutual cooperation among the three, the phenomenon of the metal mesh layer 8 and the fabric spreading and loosening can be reduced: a fabric base layer 1, a wear-resistant layer 6 is arranged on the uppermost part of the fabric base layer 1, and wear-resistant protrusions 7 are arranged on the upper surface of the wear-resistant layer 6. A metal mesh layer 8 is arranged between the fabric base layer 1 and the wear-resistant layer 6, and a fixing base layer for firmly fixing it is arranged on the lower side of the metal mesh layer 8. The bending, wear-resistant and impact-resistant properties of the composite fabric can be improved through the metal mesh layer 8. The side of the metal mesh layer 8 is fixedly connected with a metal connecting bar 16, and docking buckles 17 are fixedly connected to both the left and right ends of the metal connecting bar 16, and the notches of the docking buckles 17 on the left and right sides face in opposite directions. The wear-resistant layer 6 is arranged above the metal mesh layer 8, and the side of the lower surface of the wear-resistant layer 6 is fixedly connected with an upper connecting rope 11, and the upper connecting rope 11 is engaged with the docking buckle 17 with the notch facing upward on the right side. The fixing base layer includes a lower docking layer 13, the lower docking layer 13 is fixedly connected below the metal mesh layer 8, and the side of the upper surface of the lower docking layer 13 is fixedly connected with a lower connecting rope 12, and the lower connecting rope 12 is engaged with the docking buckle 17 with the notch facing downward on the left side.

[0041] The wear-resistant layer 6 is formed by twisting high-strength and high-toughness fibers, such as polyester fibers and nylon fibers, so as to effectively resist external friction and wear. At the same time, wear-resistant protrusions 7 (yarns or cotton threads are mixed into a tough embossing roller and then rolled together with the fabric to form raised patterns and patterns on the fabric surface) are formed on the outside of the wear-resistant layer 6 by means of mechanical protrusion process. At this time, the protruding structure is used to increase the wear resistance and decorative properties of the fabric.

[0042] The metal mesh layer 8 is made of shape memory alloy. 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 stitched 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 inside the docking buckle 17 provided on the left side of the metal mesh layer 8. At the same time, the wear-resistant layer 6 is adhesively provided on the upper surface of the metal mesh layer 8. At the same time, the upper connecting rope 11 is stitched to the side of the lower surface of the wear-resistant layer 6, and the upper connecting rope 11 is clamped and placed inside the docking buckle 17 provided on the right side of the metal mesh layer 8. The metal mesh layer 8 is fixed by the clamping action between the docking buckles 17 provided on the sides of the metal mesh layer 8 through the upper connecting rope 11 and the lower connecting rope 12, so as to reduce the phenomenon of the metal mesh layer 8 coming loose from the fabric. When the wear-resistant layer 6 is bonded to the upper surface of the metal mesh layer 8, there are holes in the center of the metal mesh layer 8. The holes enable the metal mesh layer 8 to still have parts for the fabric to breathe and drain water when bonding with the wear-resistant layer 6 and the lower docking layer 13, thereby enhancing the air permeability of the composite fabric. The metal mesh layer 8 is made of shape memory alloy, which will deform or return to its pre-deformed state at normal temperature or high temperature. When the composite fabric returns to its initial state at normal temperature or in a normal state in a special environment, it will cause the composite fabric to present a certain arc, thereby changing the fitting state between the fabric and the skin and further enhancing the heat preservation or air permeability state of the fabric.

[0043] Example 2: As Figure 1 , Figure 4 and Figure 10 shown in the technical solution, the present invention provides the following technical solution: an ultra-thin long filament composite fabric and its processing technology, which discloses: wear-resistant protrusions 7. By means of the wear-resistant protrusions 7, the contact area between the lower docking layer 13 and the PA glue layer 10 can be increased, and the stability between the surface layers can be further improved. The lower side of the lower docking layer 13 is coated with a PA glue layer 10. The lower surface of the lower docking layer 13 is provided with docking protrusions 14, and the docking protrusions 14 are arranged in a rectangular array along the lower surface of the lower docking layer 13. Docking grooves 15 are formed on the upper surface of the PA glue layer 10, and the positions of the docking grooves 15 correspond to those of the docking protrusions 14 one by one.

[0044] Super-elongated polyester-cotton fiber filaments, polyester fiber filaments, and nylon fiber filaments are blended using a blended spinning machine to weave a fabric fabric base layer 1. Then, a layer of PA glue layer 10 is coated on the upper surface of the fabric fabric base layer 1. The fixed base layer is the lower docking layer 13. The fixed base layer is composed of textile materials such as cotton, polyester, and nylon, or new materials such as non-woven fabrics and films. A pressing device is used to press the composite base layer, and the pressed fixed base layer is sent to a drying device for drying treatment to form the lower docking layer 13. At this time, the lower docking layer 13 is placed above the PA glue layer 10, so that the lower docking layer 13 is adhered to the fabric fabric base layer 1 through the PA glue layer 10. 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 glue layer 10. Through the docking protrusion 14, the contact area between the lower docking layer 13 and the PA glue layer 10 is further increased, and the adhesion effect between the PA glue layer 10 and the lower docking layer 13 is improved.

[0045] Example 3: As Figures 1 - 4 shown in this technical solution, the present invention provides the following technical solution: a super-elongated filament composite fabric and its processing technology, discloses a waterproof layer 4, through which the waterproof effect of the fabric can be improved, and the phenomenon of water body exosmosis can be reduced: the lower surface of the PA glue layer 10 is coated on the upper surface of the fabric fabric base layer 1, and a hydrophobic layer 2 is provided on the lower surface of the fabric fabric base layer 1. And hydrophobic holes 3 are arranged in a rectangular array on the hydrophobic layer 2. At the same time, a waterproof layer 4 is provided on the lower surface of the hydrophobic layer 2. The left and right sides of the waterproof layer 4 bend upward and extend and are connected to the side of the upper surface of the wear-resistant layer 6. And an adsorption layer 5 is provided inside the bent extension part of the waterproof layer 4. And a diversion groove 9 is provided on the upper surface of the waterproof layer 4. The diversion groove 9 is transversely opened along the bent extension parts on both sides of the waterproof layer 4, and the side of the diversion groove 9 is opened to the lower side position of the adsorption layer 5.

[0046] The lower surface of the fabric 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 waterproof layer 4. After the waterproof layer 4 is adhered, the extra part on the side of the waterproof layer 4 is bent upward, so that the side of the waterproof layer 4 is adhered to the side of the upper surface of the wear-resistant layer 6. Through the hydrophobic holes 3 provided on the hydrophobic layer 2, the fabric fabric base layer 1 can be hydrophobic-treated, and at the same time, the water body can be blocked by the waterproof layer 4, reducing water body infiltration. A diversion groove 9 is provided on the waterproof layer 4, which can divert the blocked water body. At this time, the water body can be adsorbed by the adsorption layer 5 provided on the side of the waterproof layer 4, avoiding water body exosmosis caused by too much water body received in the waterproof layer 4. At the same time, the adsorption layer 5 adsorbs and aggregates the water body in one place, and the user can separately treat the water body at the adsorption layer 5 without performing a large-scale water body treatment on the entire composite fabric.
