[0024] Specifically, first of all, the process begins with the interlaced weaving of the first yarn 1 and the second yarn 2. This weaving method constructs a solid structure of the denim layer through the precise interweaving of the warp and weft. The denim layer not only provides the main structure of the textile, but also gives it a unique texture and style. On the basis of the denim layer, the waterproof function of the textile is achieved through the mutual cooperation of the vinylon textile yarn 101, the first waterproof layer 102, the chloroprene textile yarn 201 and the second waterproof layer 202. This design enables the textile to remain dry in a humid or water-stained environment, greatly improving its practicality. At the same time, the selection and coordination of these materials also give the textile the ability to prevent the burning of the fire source, thereby improving its safety. However, the functionality of the textile is not limited to this. In order to further enhance the performance of the textile, the third yarn 3 and the fourth yarn 4 are introduced again and woven by the interlaced method of the warp and weft to form a flame retardant layer. The construction of the flame retardant layer further improves the fire resistance of the textile, making it safer when facing a fire source. In addition, in order to prevent the generation of static electricity, the modified polyacrylonitrile fiber textile line 301, the first antistatic layer 302, the fiber textile line bundle 401 and the second antistatic layer 402 are cleverly matched together. The use of these materials and technologies enables the textile to effectively prevent the generation of static electricity while maintaining flame retardant properties, further enhancing the safety and comfort of the textile.

[0025] Reference Figure 1 and Figure 4 The fifth yarn 5 includes an elastic fiber 501, the outer wall of the elastic fiber 501 is coated with a polyester fiber 502, the polyester fiber 502 is spirally coated with cotton 503 in the same spiral direction, the outer wall of the polyester fiber 502 is coated with nylon 504, and the outer wall of the nylon 504 is coated with an elastic thread 505; the first waterproof layer 102 and the second waterproof layer 202 are both made of silicone rubber coating; the first antistatic layer 302 and the second antistatic layer 402 are both made of antistatic material;

[0026] Specifically, a skin-friendly layer is constructed by the precise interlacing of the warp and weft through four parallel fifth yarns 5. The design of this skin-friendly layer not only increases the comfort of the fabric, but also greatly improves the durability of the fabric. The introduction of the fifth yarn 5 makes the fabric more stable in structure. The interlaced weaving of the warp and weft forms a unique texture, which is not only beautiful but also greatly enhances the durability of the fabric. In this way, the fabric can better resist wear and tear in daily use, thereby extending its service life. In addition, the fiber combination in the fabric is also the key to its unique performance. The combination of elastic fiber 501, polyester fiber 502, cotton 503, nylon 504 and elastic fiber 501 makes this denim fabric achieve an excellent balance in sweat absorption and wear resistance. The addition of elastic fiber 501 and nylon 504 makes the fabric have better elasticity and wear resistance while maintaining softness and comfort. The combination of polyester fiber 502 and cotton 503 gives the fabric excellent sweat absorption and breathability, allowing the wearer to remain dry and comfortable in hot weather.

[0027] Working principle: First, the first yarn 1 and the second yarn 2 are woven in an interlaced manner of warp and weft to form a denim layer, and then the vinylon yarn 101, the first waterproof layer 102, the chloroprene yarn 201 and the second waterproof layer 202 cooperate with each other, so as to achieve the effect of waterproofing and preventing the fire source from burning. At this time, the third yarn 3 and the fourth yarn 4 are woven in an interlaced manner of warp and weft to form a flame retardant layer, and then the modified polyacrylonitrile fiber yarn 301, the first antistatic layer 302, the fiber textile bundle 401 and the second antistatic layer 402 cooperate with each other, so as to achieve the effect of preventing static electricity and further preventing the fire source from burning;
