Description

TECHNICAL FIELD

[0001] The utility model relates to the field of fabric, more particularly to a flame-retardant fabric. BACKGROUND

[0002] The flame-retardant fabric on the market at present adopts a post-processing technology such as coating or chemical finishing of a flame retardant, so that a barrier layer is formed on the surface of the fabric, thereby increasing the flame-retardant property of the fabric, but because the flame-retardant fabric is originally woven by synthetic fibers, the air permeability of the fabric is poor in itself, and the air permeability of the fabric is poor due to the additional layer of the flame retardant. SUMMARY

[0003] The utility model discloses a flame-retardant fabric, which is formed by interweaving warp yarns and weft yarns to form a base cloth area, a first air permeable area and a second air permeable area, so that the first air permeable area and the second air permeable area are evenly distributed between the base cloth area, and the first air permeable area and the second air permeable area each include air permeable holes, which are evenly distributed. Therefore, when the surface of the fabric is coated with a flame retardant, the flame retardant will form a barrier layer on the surface of the base cloth area, and the flame retardant will pass through the air permeable holes, so that the air permeable holes also become carriers of the flame retardant. Therefore, when the fabric is at high temperature, the air permeable holes can not only release the flame retardant, but also increase the air permeability of the fabric during daily use, thereby maintaining the air circulation in the room. The first air permeable area has one air permeable hole, and the second air permeable area includes a plurality of air permeable holes, so that the first air permeable area and the second air permeable area are arranged alternately. The second air permeable area forms a main air flow channel through the plurality of air permeable holes, and the first air permeable area forms an auxiliary air flow channel through the one air permeable hole, so that the indoor air flow has multiple circulation paths, and the combination of the plurality of air permeable holes and the one air permeable hole prevents the fabric from uneven heat dissipation due to only one air permeable hole, and also prevents the indoor privacy from being reduced due to multiple air permeable holes.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a flame-retardant fabric, comprising a base cloth area, a first air permeable area and a second air permeable area, the first air permeable area and the second air permeable area are connected through the base cloth area, and along the width direction of the fabric, the first air permeable area and the second air permeable area are arranged alternately, the first air permeable area includes four protruding areas and one first air permeable hole, and the second air permeable area includes a connecting area and a plurality of second air permeable holes.

[0005] The utility model is further provided to be along the length direction and the width direction of the fabric, and the second air permeable area is located in the middle of two adjacent first air permeable areas.

[0006] The utility model further sets up, along the length direction of fabric, interval 3.5 first permeable area's distance between two adjacent first permeable area, interval 3 first permeable area's distance between two adjacent second permeable area, along the width direction of fabric, interval 2.72 first permeable area's distance between two adjacent first permeable area, interval 2.9 first permeable area's distance between two adjacent second permeable area.

[0007] The utility model further sets up, the width of first permeable area along the width direction of fabric is 1.2 times of the width of second permeable area along the width direction of fabric, and the length of second permeable area along the length direction of fabric is 1.5 times of the length of first permeable area along the length direction of fabric.

[0008] The utility model further sets up, first permeable hole is square, four corners of first permeable hole are located in the middle surrounded by four convex areas, and four convex areas are connected.

[0009] The utility model further sets up, the aperture of first permeable hole is 3-9mm.

[0010] The utility model further sets up, second permeable hole is square, and the distance between two adjacent second permeable holes is the aperture of a second permeable hole.

[0011] The utility model further sets up, the aperture of second permeable hole is 1-3mm.

[0012] The utility model further sets up, and fabric is formed by 134 warp yarns and 162 weft yarns interweave, and first permeable area is formed by 36 warp yarns and 36 weft yarns interweave, and second permeable area is formed by 30 warp yarns and 54 weft yarns interweave.

[0013] Summarized above, the utility model has following beneficial effect:

[0014] The fabric is formed by interlacing warp and weft yarns into a base fabric area, a first breathable area, and a second breathable area. Both the first and second breathable areas have ventilation holes. When the fabric is coated with flame retardant, the fibers on the surface of the ventilation holes also increase the flame retardant, thus forming a carrier for the flame retardant. Therefore, when the fabric comes into contact with high temperatures, a flame retardant layer is formed on the fabric surface, and the ventilation holes release the flame retardant. In addition, the ventilation holes can increase air circulation in a normal temperature environment, thereby improving the breathability of the fabric. The first breathable area includes one ventilation hole, while the second breathable area includes multiple ventilation holes. Therefore, the ventilation holes in the first and second breathable areas are evenly distributed, and the first breathable area assists the second breathable area in forming an airflow channel, thus creating multiple air circulation paths on the fabric surface. Through the alternating arrangement of multiple ventilation holes and one ventilation hole, the breathability of the fabric is increased while the fabric can protect indoor privacy.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1—4, the present embodiment discloses a warm-keeping fabric, which comprises a base fabric area 100, a first air-permeable area 200 and a second air-permeable area 300. In the present embodiment, the fabric is formed by interweaving 134 warp yarns and 162 weft yarns. The first air-permeable area 200 is formed by interweaving 36 warp yarns and 36 weft yarns. In one weave cycle, the first air-permeable area 200 is formed by interweaving the first 36 warp yarns and the 59th to 94th weft yarns. Within the interweaving range of the first 36 warp yarns and the 59th to 94th weft yarns, the first 14 warp yarns and the 59th to 72nd weft yarns interweave to form an area, the 19th to 32nd warp yarns and the 59th to 72nd weft yarns interweave to form an area, the first 14 warp yarns and the 77th to 90th weft yarns interweave to form an area, and the 19th to 32nd warp yarns and the 77th to 90th weft yarns interweave to form an area. Because within the interweaving range of the first 14 warp yarns and the 59th to 72nd weft yarns, the 59th, 60th, 63rd, 64th, 67th, 68th, 71st and 72nd weft yarns interweave with the warp yarns to form float lines, and the 61st, 62nd, 65th, 66th, 69th and 70th weft yarns interweave with the warp yarns to form weave points, the weave points are interwoven by warp and weft yarns, so that the fabric is thin and concave at the interweaving position, and the float lines make the warp yarns close to each other and protrude. Within the interweaving range of the first 14 warp yarns and the 77th to 90th weft yarns, the first, second, fifth, sixth, ninth, tenth, 13th and 14th warp yarns interweave with the weft yarns to form float lines, and the third, fourth, seventh, eighth, 11th and 12th warp yarns interweave with the weft yarns to form weave points, so that the weave points are interwoven by warp and weft yarns, so that the fabric is thin and concave at the interweaving position, and the float lines make the weft yarns close to each other and protrude. Because the area formed by interweaving the first 14 warp yarns and the 59th to 72nd weft yarns and the area formed by interweaving the 19th to 32nd warp yarns and the 77th to 90th weft yarns have the same weave, and the area formed by interweaving the 19th to 32nd warp yarns and the 59th to 72nd weft yarns and the area formed by interweaving the 19th to 32nd warp yarns and the 59th to 72nd weft yarns have the same weave, the first air-permeable area 200 comprises four protruding areas 201. Because the four protruding areas 201 are connected by interweaving the 15th to 18th warp yarns and the 59th to 90th weft yarns, and simultaneously connected by interweaving the first to 32nd warp yarns and the 73rd to 76th weft yarns, a cross-shaped connecting area is formed between the four protruding areas 201. Because the cross-shaped connecting area is an interweaving point, and the four protruding areas 201 are float lines, the warp and weft yarns of the cross-shaped connecting area are pulled by the protruding of the four protruding areas 201, so that a gap is formed between the four protruding areas 201, and the gap is arranged in a cross shape. Therefore, the interweaving position of the 15th to 18th warp yarns and the 73rd to 76th weft yarns is located at the four corner connecting positions of the four protruding areas 201, so that the interweaving position of the 15th to 18th warp yarns and the 73rd to 76th weft yarns is pulled by the four protruding areas 201, so that the aperture formed by the interweaving of the 15th to 18th warp yarns and the 73rd to 76th weft yarns is the largest, and a ventilation hole is formed in the middle of the four protruding areas 201, so that the first air-permeable area 200 comprises a first ventilation hole 202.And the first air permeable hole 202 is located in the middle of the four convex areas 201, and the four corners of the first air permeable hole 202 are connected with the four convex areas 201, because the first air permeable hole 202 is located at the intersection of the 15th-18th warp yarns and the 73rd-76th weft yarns, so the first air permeable hole 202 is square, and when the fabric is coated with flame retardant, the surface of the first air permeable hole 202 will also become the carrier of the flame retardant, so when the surface of the fabric contacts high temperature, after the surface releases the flame retardant, the first air permeable hole 202 located on the surface of the fabric will release the flame retardant, and because the fabric has a certain thickness, the first air permeable hole 202 located in the interior of the fabric will also release the flame retardant, thereby inhibiting the spread of flames in the external environment, and increasing the air permeability of the fabric through the first air permeable hole 202, which can increase the air circulation in the room during daily use.

[0022] The second air permeable area 300 is formed by interweaving 30 warp yarns and 54 weft yarns, and in the interweaving range of the 30 warp yarns and the 54 weft yarns, the 39th-44th warp yarns and the 3rd-8th weft yarns are interwoven to form an air permeable hole, so in the interweaving range of the 30 warp yarns and the 54 weft yarns, every 6 warp yarns and every 6 weft yarns are interwoven to form an air permeable hole, so the second air permeable area 300 includes a plurality of second air permeable holes 302, because each second air permeable hole 302 is naturally formed by the internal stress between fibers after interweaving 6 warp yarns and 6 weft yarns, so the 6 warp yarns and 6 weft yarns that form each second air permeable hole 302 are the connection area 301, so the second air permeable area 300 also includes the connection area 301, because the second air permeable hole 302 is formed by the internal stress generated after interweaving 6 warp yarns and 6 weft yarns, and the second air permeable hole 302 is located in the middle of the interweaving of the 6 warp yarns and the 6 weft yarns, so the second air permeable hole 302 is also square, and the internal stress after interweaving every 3 warp yarns and every 3 weft yarns forms one side of the square of the second air permeable hole 302, and each second air permeable hole 302 is formed by interweaving 6 warp yarns and 6 weft yarns in a cycle, so the distance between the adjacent two second air permeable holes 302 is the aperture of a second air permeable hole 302, so that the second air permeable holes 302 can be evenly distributed in the second air permeable area 300, when the fabric is coated with flame retardant, each second air permeable hole 302 is the same as the first air permeable hole 202, the second air permeable hole 302 will not only release the flame retardant on the surface of the fabric, but also release the flame retardant in the interior of the fabric, thereby inhibiting the spread of flames in the room, and because of the uniform distribution of the second air permeable hole 302, the air permeability of the fabric is increased while maintaining air circulation in the room during daily use.

[0023] Because the square of the first air vent 202 is formed by the interlacing of the fibers of the four raised areas 201, and the square of the second air vent 302 is formed by the interlacing of 6 warp yarns and 6 weft yarns, the aperture of the second air vent 302 is smaller than the aperture of the first air vent 202, so the aperture of the first air vent 202 is 3-9mm, preferably, the aperture of the first air vent 202 is 5mm, and the aperture of the second air vent 302 is 1-3mm, preferably, the aperture of the second air vent 302 is 1.7mm, because the aperture of the second air vent 302 is smaller than the aperture of the first air vent 202, but the number of the second air vent 302 is greater than the number of the first air vent 202, so the second air vent area 300 forms the main air flow channel through multiple second air vents 302, and one first air vent 202 in the first air vent area 200 forms an auxiliary air flow channel, because the first air vent area 200 is located in the interlacing range of the 1st-36th warp yarns and the 59th-94th weft yarns, and the second air vent area 300 is located in the interlacing range of the 39th-68th warp yarns and the 3rd-56th weft yarns, so the 1st-38th warp yarns and the 1st-58th weft yarns include the interlacing of the circulating number to form the base fabric area 100, the 39th-68th warp yarns and the 57th-94th weft yarns include the interlacing of the circulating number to form the base fabric area 100, and the 69th-70th warp yarns and the 1st-94th weft yarns include the interlacing of the circulating number to form the base fabric area 100, so in one weave cycle, the first air vent 200 and the second air vent area 300 are connected through the base fabric area 100, and along the width direction of the fabric, the first air vent area 200 and the second air vent area 300 are arranged alternately, so that the auxiliary air flow channel formed by one first air vent 202 and the main air flow channel formed by multiple second air vents 302 are arranged and combined in a certain rule, thereby making the air vents evenly distributed, making the air permeability of the fabric more uniform, at the same time, increasing the air flow through the main air flow channel, and dispersing the air flow through the auxiliary air flow channel, thereby making the indoor air flow have multiple paths, thereby increasing the overall air permeability of the fabric, and when the fabric is in contact with high temperature, the main air flow channel can quickly disperse and discharge heat, and the auxiliary air flow channel can concentrate and discharge heat, thereby reducing the surface temperature of the fabric, and the combination of multiple second air vents 302 and one first air vent 202 will increase the air permeability compared to the fabric with only first air vents 202, and will also help to protect privacy compared to the fabric with only second air vents 302.

[0024] Because the first air permeable zone 200 is located in the interlacing range of the 1st-36th warp yarns and the 59th-94th weft yarns, and the second air permeable zone 300 is located in the interlacing range of the 39th-68th warp yarns and the 3rd-56th weft yarns, along the width direction of the fabric, the 37th-38th warp yarns form a cyclic arrangement of 17 times, and the 69th-70th warp yarns also form a cyclic arrangement of 17 times, thus the second air permeable zone 300 is spaced apart from the first air permeable zone 200 by the same number of warp yarns along the width direction of the fabric, thus along the width direction of the fabric, the second air permeable zone 300 is located in the middle of two adjacent first air permeable zones 200, while along the length direction of the fabric, the 1st-2nd weft yarns form a cyclic arrangement of 18 times, and the 57th-58th weft yarns also form a cyclic arrangement of 18 times, thus the second air permeable zone 300 is spaced apart from the first air permeable zone 200 by the same number of weft yarns along the length direction of the fabric, thus along the length direction of the fabric, the second air permeable zone 300 is located in the middle of two adjacent first air permeable zones 200, thus the first air permeable zone 200 and the second air permeable zone 300 can be evenly distributed, so that the overall fabric maintains the stability of air permeability and flame retardance.

[0025] Because the first air permeable zone 200 is formed by interlacing 36 warp yarns and 36 weft yarns, and along the length direction of the fabric, two adjacent first air permeable zones 200 are spaced apart by 126 weft yarns, thus along the length direction of the fabric, two adjacent first air permeable zones 200 are spaced apart by a distance of 3.5 first air permeable zones 200, while along the width direction of the fabric, two adjacent first air permeable zones 200 are spaced apart by 98 warp yarns, thus along the width direction of the fabric, two adjacent first air permeable zones 200 are spaced apart by a distance of 2.72 first air permeable zones 200, because the second air permeable zone 300 is formed by interlacing 30 warp yarns and 54 weft yarns, and along the length direction of the fabric, two adjacent second air permeable zones 300 are spaced apart by 108 weft yarns, thus along the length direction of the fabric, two adjacent second air permeable zones 300 are spaced apart by a distance of 3 first air permeable zones 200, while along the width direction of the fabric, two adjacent second air permeable zones 300 are spaced apart by 104 warp yarns, thus along the width direction of the fabric, two adjacent second air permeable zones 300 are spaced apart by a distance of 2.9 first air permeable zones 200, thus the first air permeable zone 200 and the second air permeable zone 300 are maintained within a distance of 3 first air permeable zones 200 in the up-down direction and the left-right direction, thus the combination of the auxiliary airflow channel of the first air permeable zone 200 and the main airflow channel of the second air permeable zone 300 can increase the airflow path of the fabric, so that when the fabric encounters high-temperature combustion, the flame propagation speed can be slowed down while the heat energy of the flame is dispersed, and the air permeability of the fabric is increased in daily life, thus increasing the air flow in the room.

[0026] Because the first air permeable area 200 has 36 warp yarns and the second air permeable area 300 has 30 warp yarns, the width of the first air permeable area 200 along the width direction of the fabric is 1.2 times the width of the second air permeable area 300 along the width direction of the fabric, because the first air permeable area 200 has 36 weft yarns and the second air permeable area 300 has 54 weft yarns, the length of the second air permeable area 300 along the length direction of the fabric is 1.5 times the length of the first air permeable area 200 along the length direction of the fabric, so that the main air flow passage formed by the second air permeable holes 302 is larger than the auxiliary air flow passage formed by the first air permeable holes 202, so that more air flow passage paths are provided by the second air permeable area 300 through the plurality of second air permeable holes 302, while the first air permeable area 200 controls the concentration of air flow through the one first air permeable hole 202, and because the aperture of the first air permeable hole 202 is larger than the aperture of the second air permeable hole 302, the first air permeable hole 202 and the second air permeable hole 302 are not blocked by the fire retardant coating when the fabric surface is coated with the fire retardant coating, while the air permeability of the fabric is increased, so that the safety and air flow of the indoor environment are maintained, and the combination of the first air permeable hole 202 and the second air permeable hole 302 can increase the air permeability of the fabric while increasing the protection provided by the fabric.

[0027] 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 falling within the concept of the present application belongs to 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 principles of the present application can also be considered as the protection scope of the present application.
