When there is a triangular antibacterial fabric B between every two triangular antibacterial fabrics A, place a triangular bracket-shaped rubber sheet A on the upper end surface of the triangular antibacterial fabric B. When a triangular bracket-shaped rubber sheet A is placed on each triangular antibacterial fabric B, lay a layer of triangular antibacterial fabric A on the triangular antibacterial fabric B that has just been laid. When three layers of the triangular antibacterial fabric A and the triangular antibacterial fabric B are laid, the process is completed;

[0016] Step D: After the triangular antibacterial fabrics A and B are laid out, pick up a layer of tensile-resistant layer and cover the upper end surfaces of all the triangular antibacterial fabrics A and B with the tensile-resistant layer. Then, align the weaving thread on the outer surface of the tensile-resistant layer with the connection between the triangular antibacterial fabrics A and B, and move up and down in a wavy line at this position, so as to weave the tensile layer, the triangular antibacterial fabric A and the triangular antibacterial fabric B to fix the three together.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention provides three layers of triangular antibacterial fabric A and three layers of triangular antibacterial fabric B in the shape of a triangular bracket inside the tear-resistant layer, and sews all the triangular antibacterial fabric A and triangular antibacterial fabric B to the anti-tension layer through a braided thread. When the anti-tension layer itself is pulled, the triangular antibacterial fabric A and triangular antibacterial fabric B inside it will be deformed accordingly. During the deformation process, the triangular antibacterial fabric A and triangular antibacterial fabric B will squeeze the triangular antibacterial fabric A and triangular antibacterial fabric B between each layer. The bracket-shaped rubber sheet A and the triangular bracket-shaped rubber sheet B cause the tensile layer to be deformed. When the external force pulls the tensile layer, the pulling force will also act on all the triangular bracket-shaped rubber sheets A and the triangular bracket-shaped rubber sheets B. Since the triangular bracket-shaped rubber sheets A and the triangular bracket-shaped rubber sheets B are made of rubber in one piece and have a certain elasticity, when the tensile layer is pulled to cause the tensile layer to be deformed, the triangular bracket-shaped rubber sheets A and the triangular bracket-shaped rubber sheets B can offset a part of the external pulling force. The above technical solution improves the tear resistance of the fabric itself.

[0031] 2. In the process of producing the tensile layer, the present invention requires that the tensile layer be immersed in a resin solvent for an additional half an hour. After the tensile layer absorbs the resin solvent, the tensile resistance of the tensile layer itself and the wear resistance of its surface can be enhanced. The above technical solution improves the tensile resistance of the surface of the tear-resistant layer, preventing the situation where the outer surface is torn instead of the inner part being torn due to external pulling force.

[0041] A triangular bracket-shaped rubber sheet B9 is provided between every two triangular antibacterial fabrics A5. The lower end face of the triangular bracket-shaped rubber sheet B9 is a cone angle of ninety degrees. The lower end face of the triangular bracket-shaped rubber sheet B9 is fitted with the inner wall of the triangular antibacterial fabric A5 located below it. An isosceles triangle groove B11 is provided on the lower end face of the triangular bracket-shaped rubber sheet B9. The lower end face of the triangular antibacterial fabric A5 located above the triangular bracket-shaped rubber sheet B9 is fitted with the inner wall of the isosceles triangle groove B11.

[0042] The tear-resistant layer 1 also includes two tensile-resistant layers 3, the first tensile-resistant layer 3 from top to bottom covers the upper end surfaces of the triangular antibacterial fabrics A5 and B6 located at the top, and the second tensile-resistant layer 3 from top to bottom covers the lower end surfaces of the triangular antibacterial fabrics A5 and B6 located at the bottom; a braided wire 8 located inside the tensile-resistant layer 3 is provided on both sides above the triangular antibacterial fabric B6 located at the top, and the braided wire 8 punctures the connection position between the triangular antibacterial fabric A5 and the triangular antibacterial fabric B6 in an upward and downward cycle; an expansion groove B13 is provided between the two ends of the triangular bracket-shaped rubber sheet B9 and the triangular antibacterial fabric B6, and an expansion groove A12 is provided between the two ends of the triangular bracket-shaped rubber sheet A7 and the triangular antibacterial fabric A5, and the triangular bracket-shaped rubber sheet A7 and the triangular bracket-shaped rubber sheet B9 are both made of integrated rubber.

[0043] The preparation method of the tear-resistant layer 1 comprises the following steps:

[0044] First, lay a layer of tensile layer 3 on the weaving table, and then lay a layer of triangular antibacterial fabric A5 on the tensile layer 3 at intervals with the pointed cone head of the triangular antibacterial fabric A5 facing downwards, and ensure that the distance between the triangular antibacterial fabric A5 is smaller than the distance between the two side vertices of the upper end surface of the triangular antibacterial fabric A5;

[0045] After the triangular antibacterial fabric A5 is laid out, pick up the same number of triangular bracket-shaped rubber sheets B9 as the triangular antibacterial fabric A5, and place a triangular bracket-shaped rubber sheet B9 inside each triangular antibacterial fabric A5;

[0046] After the triangular bracket-shaped rubber sheet B9 is placed, pick up the triangular antibacterial cloth B6, with the pointed cone of the triangular antibacterial cloth B6 facing upwards, and place a triangular antibacterial cloth B6 in the gap between every two triangular antibacterial cloths A5. When there is a triangular antibacterial cloth B6 between every two triangular antibacterial cloths A5, place a triangular bracket-shaped rubber sheet A7 on the upper end surface of the triangular antibacterial cloth B6. When a triangular bracket-shaped rubber sheet A7 is placed on each triangular antibacterial cloth B6, lay a layer of triangular antibacterial cloth A5 on the triangular antibacterial cloth B6 that has just been laid. When three layers of triangular antibacterial cloth A5 and triangular antibacterial cloth B6 are laid, it is ready.

[0047] After the triangular antibacterial fabrics A5 and B6 are laid, a layer of tensile-resistant layer 3 is picked up and the tensile-resistant layer 3 is covered on the upper end surfaces of all the triangular antibacterial fabrics A5 and B6. Then the braiding thread 8 is aligned with the connection between the triangular antibacterial fabrics A5 and B6 on the outer surface of the tensile-resistant layer 3, and moves up and down in a wavy line at this position to weave the tensile-resistant layer 3, the triangular antibacterial fabric A5 and the triangular antibacterial fabric B6 and fix them together. After the weaving is completed, the interior of the tear-resistant layer 1 is provided with three layers of triangular antibacterial fabrics A5 and three layers of triangular antibacterial fabrics B6 in the shape of a triangular bracket, and all the triangular antibacterial fabrics A5 and B6 are sewn and fixed to the tensile-resistant layer 3 by the braiding thread 8. When the tensile-resistant layer 3 itself is pulled, the triangular antibacterial fabrics A5 and B6 inside it will be deformed accordingly, and the triangular antibacterial fabrics A5 and B6 will be deformed. During the deformation process, the antibacterial cloth B6 will squeeze the triangular bracket-shaped rubber sheet A7 and the triangular bracket-shaped rubber sheet B9 between each layer of the triangular antibacterial cloth A5 and the triangular antibacterial cloth B6 to deform them. The expansion grooves A12 and B13 located on one side of the triangular bracket-shaped rubber sheet A7 and the triangular bracket-shaped rubber sheet B9 can provide deformation space for the triangular bracket-shaped rubber sheet A7 and the triangular bracket-shaped rubber sheet B9. When the external force pulls the tensile layer 3, its pulling force will also act on all the triangular bracket-shaped rubber sheets A7 and the triangular bracket-shaped rubber sheets B9. Since the triangular bracket-shaped rubber sheets A7 and the triangular bracket-shaped rubber sheets B9 are both made of integrated rubber and have a certain elasticity, in the process of pulling the tensile layer 3 to deform it, a part of the external pulling force can be offset by the triangular bracket-shaped rubber sheets A7 and the triangular bracket-shaped rubber sheets B9. The above technical solution improves the tear resistance of the tear-resistant layer 1 itself.

[0048] From top to bottom, the upper end surface of the first tensile layer 3 and the lower end surface of the second tensile layer 3 are coated with a layer of coating 2, and the outer surface of the coating 2 is provided with a plurality of through holes 4, and the through holes 4 extend to the interior of the tensile layer 3 by penetrating the coating 2; the coating 2 is an epoxy coating, a polyester coating or a PA coating; the highly elastic epoxy coating, polyester coating or PA coating can prevent the surface coating from generating cracks when the tear-resistant layer 1 is pulled.

[0049] The tensile layer 3 includes the following components according to their weight fractions: cotton fiber: 50-70 parts, polyester fiber: 20-40 parts, elastic fiber: 5-20 parts, silver nanowire: 0.5-3 parts, antistatic agent: 1-6 parts, antibacterial agent: 10-20 parts, modified glass fiber: 20-30, aramid fiber: 30-40 parts, concentrated alkali solution: 20-30 parts and resin solvent: 10-20 parts.

[0050] The preparation method of the tensile layer 3 is as follows;

[0051] Cotton fiber, polyester fiber, elastic fiber, modified glass fiber and aramid fiber are mixed in corresponding proportions to make them into basic fibers for fabrics;

[0052] During the mixing process, corresponding proportions of silver nanowires were added to the interior of the fiber mixture in four batches;

[0053] When the silver nanowires were added, the antistatic agent and antimicrobial agent were gradually added to the mixture;

[0054] After the mixing is completed, the mixed fibers are spun and woven into yarn. During this process, the stretching and twist of the fibers can be adjusted to increase the strength and toughness of the yarn. Finally, the yarn is woven into yarn fabrics through a spinning machine.

[0055] After the fabric is woven, the fluff on the fabric is removed by high-temperature flames or red-hot metal surfaces to make the fabric smooth and beautiful, and to prevent uneven dyeing and printing defects caused by the presence of fluff during dyeing and printing.

[0056] Then soak it in the resin solvent for half an hour to enhance the tensile and abrasion resistance of the fabric.

[0057] After half an hour, place it in a high-temperature concentrated alkali solution and boil it for an hour to remove residual impurities on the fabric; to ensure the fabric's dimensional stability and comfortable feel;

[0058] Finally, it undergoes dyeing, cleaning, drying, shaping and other processing steps.

[0059] This occurs during the production of the tensile layer 3, which needs to be immersed in the resin solvent for an additional half an hour. After the tensile layer 3 absorbs the resin solvent, the tensile resistance of the tensile layer 3 itself and its surface wear resistance can be enhanced. The above technical solution improves the tensile resistance of the surface of the tear-resistant layer 1, preventing the situation where the outer surface is torn instead of the inner part being torn due to external pulling force.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
