[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] As Figure 1A fireproof flame-retardant fabric is shown in FIG. 5, which includes a flame-retardant layer 10, a heat-insulating water-absorbing layer 20, and a breathable layer 30 from top to bottom. The flame-retardant layer 10 is located at the outermost layer, the breathable layer 30 is located at the innermost layer, and the heat-insulating water-absorbing layer 20 is located at the intermediate layer. The flame-retardant layer 10 includes a flame-retardant base 101 and a hydrophobic part 102, and the breathable layer 30 includes a breathable base 301. The flame-retardant base 101 and the breathable base 301 include warp yarns and weft yarns. The warp yarns and weft yarns of the flame-retardant base 101 are made of aramid fiber 103, and the warp yarns and weft yarns of the breathable base 301 are made of polypropylene fiber 303. Referring to Figure 4 The flame-retardant base 101 and the breathable base 301 are formed by interweaving yarns once. Eight warp yarns and eight weft yarns in the warp direction form one cycle. The 1st, 3rd, 5th, and 7th warp yarns and the 1st, 3rd, 5th, and 7th weft yarns are interwoven to form the flame-retardant base 101. The 2nd, 4th, 6th, and 8th warp yarns and the 2nd, 4th, 6th, and 8th weft yarns are interwoven to form the breathable base 301. On the 1st, 3rd, 5th, and 7th warp yarns, " indicates that the warp yarns of the flame-retardant base 101 are above the weft yarns to form warp points. " indicates that the warp yarns of the flame-retardant base 101 are below the weft yarns to form weft points. " indicates the weft yarns of the breathable base 301 during weaving, and the warp yarns of the flame-retardant base 101 are lifted. On the 2nd, 4th, 6th, and 8th warp yarns, " indicates that the warp yarns of the breathable base 301 are above the weft yarns to form warp points. " indicates that the warp yarns of the breathable base 301 are below the weft yarns to form weft points on the 2nd and 6th weft yarns. " indicates that the weft yarns of the breathable base 301 are above the warp yarns of the flame-retardant base 101 and the warp yarns of the breathable base 301 during weaving on the 1st, 3rd, 5th, and 7th weft yarns. The 1st, 3rd, 5th, and 7th warp yarns and the 1st, 3rd, 5th, and 7th weft yarns are all aramid fiber 103, and the 2nd, 4th, 6th, and 8th warp yarns and the 2nd, 4th, 6th, and 8th weft yarns are all polypropylene fiber 303. This arrangement results in a 1:1 arrangement of aramid fiber 103 and polypropylene fiber 303 in the warp direction and a 1:1 arrangement of aramid fiber 103 and polypropylene fiber 303 in the weft direction. This arrangement results in the interweaving of warp and weft to form a fabric with the flame-retardant layer 10 on the outside of the breathable layer 30. The flame-retardant base 101 and the breathable base 301 are connected by yarn interweaving, and a hollow part 40 is formed inside. The presence of the hollow part 40 allows air to flow between the flame-retardant base 101 and the breathable base 301.

[0022] The fireproof layer 10 uses aramid fiber 103 of 20-40 English yarn, preferably, the fireproof layer 10 uses aramid fiber 103 of 30 English yarn, the breathable layer 30 uses polypropylene fiber 303 of 40-60 English yarn, preferably, the breathable layer 30 uses polypropylene fiber 303 of 50 English yarn, because the fireproof layer 10 and the breathable layer 30 are formed by interweaving warp and weft yarns once, the warp density of the interweaving of the yarns of the fireproof layer 10 and the breathable layer 30 is 180-210 per 5 cm, preferably, the warp density is 198 per 5 cm, the weft density is 80-120 per 5 cm, preferably, the weft density is 98 per 5 cm, referring to Figure 5 , the yarns of the fireproof layer 10 and the breathable layer 30 are woven by four needles, and there is an empty needle between every four needles, and because the yarn count of the fireproof layer 10 is thick and the yarn count of the breathable layer 30 is thin, under the same density, the breathable layer 30 forms a breathable hole 302 at the empty needle, the breathable hole 302 is arranged in a matrix, and the breathable layer 30 is interwoven by polypropylene fiber 303, so when water vapor is generated, the water vapor is discharged through the breathable hole 302 by the hydrophobic property of the polypropylene fiber 303, and the water vapor is evaporated by the air flow through the hollow part 40 formed between the fireproof base 101 and the breathable base 301, so that the overall fabric remains dry, and because the yarns of the fireproof layer 10 and the breathable layer 30 are woven by four needles, the breathable base 301 is located in the four needles, so the breathable hole 302 is empty, so when weaving, the width of the breathable base 301 is 3-3.5 times the width of the breathable hole 302, preferably, the width of the breathable base 301 is 3.2 times the width of the breathable hole 302, so as to avoid sewing on the breathable hole 302 when sewing the subsequent three layers, thereby affecting the connection of the three layers and the air permeability.

[0023] The heat insulation and water absorption layer 20 is arranged in the hollow part 40.

[0024] The flame-retardant layer 10, the heat-insulating water-absorbing layer 20 and the air-permeable layer 30 are connected by sewing the hydrophobic part 102, the hydrophobic part 102 adopts hydrophobic yarn, the hydrophobic yarn is arranged in a cross shape, when the flame-retardant layer 10 is located at the outermost layer, therefore the hydrophobic part 102 can repel part of water vapor absorbed by the fabric, thereby reducing the entry of water vapor, because the width of the air-permeable base 301 is 3.2 times the width of the air-permeable hole 302, therefore when the hydrophobic part 102 connects the three layers, the hydrophobic part 102 passes through the flame-retardant base 101, the heat-insulating water-absorbing layer 20 and the air-permeable base 301, therefore the hydrophobic part 102 is located in the middle of the two air-permeable holes 302, thereby not only connecting the three layers, but also not affecting the air permeability of the air-permeable layer 30 after the three layers are connected, at the same time because the hydrophobic part 102 is arranged in a cross shape, therefore except for the three layers connected by the hydrophobic part 102, the rest are not connected, therefore the air flowability inside the three-layer fabric is increased, thereby increasing the air permeability of the fabric, keeping dry and temperature, thereby the aramid fiber 103 is not affected, after the three layers are connected, the essential flame-retardant fabric is formed, without increasing the coating of chemical additives, so that the fabric is safer and the fire-retardant effect is more durable.

[0025] The preferred embodiments of the present application are described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solution belonging to the idea of the present application is within the protection scope of the present application. It should be noted that for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application, these improvements and decorations should also be considered as the protection scope of the present application.
