Description

Technical Field

[0001] The utility model belongs to the field of special fabrics, in particular to a flame-retardant and arc-proof special work clothing fabric. Background Art

[0002] Special work clothing fabrics are usually designed to meet the requirements in specific occupations or working environments. These fabrics need to have characteristics such as wear resistance, tear resistance, waterproofness, fire resistance, anti-static, and chemical corrosion resistance.

[0003] Flame-retardant and arc-proof fabrics are designed to provide additional protection in dangerous environments, mainly to prevent factors such as flames, electric arcs, and static electricity from causing harm to the wearer. Therefore, this kind of fabric needs to have flame-retardant and arc-proof functions.

[0004] After an electric arc is generated, an explosion is likely to occur on the surface of the fabric. This explosion will bring a very high temperature. Although the duration of this high temperature is short, the impact on the fabric is relatively serious, and the heat generated by the high temperature will penetrate the fabric and act on the wearer. For existing flame-retardant and arc-proof fabrics, although they have the effects of arc-proof and flame-retardant, they cannot resist the heat penetration generated by this high temperature. After wearing, it is easy to feel a local heat burning sensation.

[0005] Therefore, a special fabric that can resist heat penetration and has flame-retardant and anti-telephone functions is needed. Summary of the Invention

[0006] The utility model provides a flame-retardant and arc-proof special work clothing fabric. The surface layer as a whole adopts a multi-layer structure, the surface layer strengthens the tightness to improve the flame-retardant and arc-proof performance, and an insulating layer is arranged inside to block the high-temperature heat penetration through the insulating layer and avoid the high-temperature heat directly acting on the wearer.

[0007] The specific technical solution of the utility model is: a flame-retardant and arc-proof special work clothing fabric, which as a whole adopts a multi-layer structure. The surface layer adopts a flame-retardant and arc-proof layer with a joined double-layer tissue structure, the inner layer adopts an insulating layer, and the innermost layer is a moisture absorption and sweat discharge layer. The flame-retardant and arc-proof layer is woven by an interweaving method with flame-retardant and arc-proof yarns, and the insulating layer adopts a structure with an insulating fabric as the main body and a microporous film covering the surface.

[0008] The fabric adopts a multi-layer structure, which can integrate multiple functions into the fabric to meet the needs of the fabric's composite functions; the surface layer adopts a flame-retardant and arc-proof layer, so that the surface of the fabric has flame-retardant and arc-proof properties. The flame-retardant and arc-proof layer is woven from flame-retardant and arc-proof yarns, making full use of the flame-retardant and arc-proof characteristics of the flame-retardant and arc-proof yarns. The flame-retardant and arc-proof yarns are woven into a joined double-layer structure by the interweaving method. The double-layer structures support each other, thereby improving the overall stability and tear resistance of the fabric to meet the working wear needs of work clothing fabrics; the joined double-layer structure woven by the interweaving method can increase the thickness of the flame-retardant and arc-proof layer, thereby improving the arc-proof effect; the fabric adds a heat-insulating layer as the inner layer. The heat-insulating layer can resist the heat penetration of high temperature, thereby blocking high temperature and avoiding heat burns to the wearer. As the main heat-insulating fabric, it has heat-insulating properties and a microporous film on the surface, which can also improve the effective blocking of the heat-insulating layer against heat radiation and heat conduction. At the same time, the microporous film also has a certain air permeability, echoing with the moisture-absorbing and sweat-wicking layer on the inner layer to improve the moisture-absorbing and sweat-wicking effect of the inner layer; flame-retardant and arc-proof work clothing fabrics are generally made into protective clothing, and the working environment temperature is relatively high. Therefore, the wearer is prone to sweating, and long-term wearing is likely to cause physical discomfort. Therefore, the moisture-absorbing and sweat-wicking requirements of work clothing fabrics need to be considered. A moisture-absorbing and sweat-wicking layer is set on the surface of the heat-insulating layer to improve the moisture-absorbing and sweat-wicking effect of the work clothing fabric, which helps to improve the wearing comfort of the protective clothing.

[0009] Preferably, the flame-retardant and arc-proof yarn is mainly made of flame-retardant viscose fiber and blended with polyimide fiber. The yarn count is at least 100 counts. The flame-retardant and arc-proof yarns are woven into a plain weave. The warp and weft density during the interweaving of the flame-retardant and arc-proof yarns is 60X60. Flame-retardant viscose fiber is a special fiber. In addition to retaining the original properties of viscose fiber, it also has increased flame-retardant properties, which can effectively slow down or prevent the spread of flames, so that the fabric has a strong flame-retardant effect and alleviates the harm caused by arc explosions to the fabric; polyimide fiber is a high-performance synthetic fiber with excellent thermal stability, mechanical properties and chemical stability. It has good high-temperature resistance itself. Even at high temperatures, it can still maintain high strength and modulus. At the same time, it also has good resistance to radiation. The good dielectric properties of polyimide fiber endow it with excellent electrical insulation and arc resistance; the surface layer is woven from flame-retardant and arc-proof yarns. The main body of the flame-retardant and arc-proof yarn is a blend of flame-retardant viscose fiber and polyimide fiber, making the flame-retardant and arc-proof yarn have excellent flame-retardant and arc-proof effects. The plain weave formed by interweaving can make the surface layer interweave tightly and evenly, thereby improving the flame-retardant and arc-proof properties of the surface layer. The yarn count of the interwoven yarns is above 100 counts, and the warp and weft density is controlled to ensure the tightness of the surface layer interweaving.

[0010] Preferably, the main body of the heat insulation layer is woven from polyimide yarns. The microporous film on the surface of the main body is an alumina microporous film. The microporous film has two layers, which are respectively located on the two surfaces of the main body. Polyimide yarns can withstand extreme high-temperature environments without melting and can maintain stable high-temperature resistance even after long-term use, so that the heat insulation layer can play a role in blocking heat transfer. The two surfaces of the heat insulation fabric are covered with alumina microporous films to improve the heat insulation performance of the heat insulation layer. The alumina microporous film has high heat resistance and heat insulation performance, and its light weight does not affect the flexibility of the fabric.

[0011] Preferably, the moisture absorption and sweat discharge layer is woven from bamboo fiber and modal fiber. Bamboo fiber is a natural fiber. The bamboo fiber and modal fiber are woven into the moisture absorption and sweat discharge layer, so that the inner layer of the fabric can discharge the sweat on the wearer's body surface and improve the comfort of the wearer's body surface.

[0012] Preferably, a heat conduction layer is arranged between the surface layer and the inner layer. The heat conduction layer is made of a hexagonal honeycomb structure woven from carbon fiber. The explosion generated when the electric arc touches the surface of the fabric will generate high temperature locally. A heat conduction layer is arranged between the surface layer and the inner layer, and the heat generated locally is dispersed through the heat conduction layer to reduce the temperature of this part and avoid the local high temperature exceeding the heat insulation limit of the fabric. Carbon fiber has good heat conduction performance, and the hexagonal honeycomb shape can quickly disperse the heat.

[0013] Preferably, energy-absorbing fibers are arranged in the heat conduction layer. The energy-absorbing fibers are made of polyurethane fibers. The polyurethane fibers extend from the carbon fibers and are woven into a radial structure in the hexagonal space. When the electric arc explodes, it will generate impact. Energy-absorbing fibers are arranged in the heat conduction layer and are arranged in the hexagonal space of the carbon fibers to absorb the impact energy.

[0014] The beneficial effects of the present utility model are as follows: The surface layer adopts a flame-retardant and arc-proof layer, so that the surface of the fabric has flame-retardant and arc-proof properties. The flame-retardant and arc-proof layer is woven from flame-retardant and arc-proof yarns, making full use of the flame-retardant and arc-proof characteristics of the flame-retardant and arc-proof yarns. The flame-retardant and arc-proof yarns are woven into a knotting double-layer structure by an interweaving method. The double-layer structures support each other, thereby improving the overall stability and tear resistance of the fabric and meeting the working wear needs of the work clothing fabric. The knotting double-layer structure woven by the interweaving method can increase the thickness of the flame-retardant and arc-proof layer, thereby improving the arc-proof effect. The fabric adds a heat insulation layer as the inner layer. The heat insulation layer can resist the heat penetration of high temperature, thereby blocking high temperature and avoiding thermal burns to the wearer. The heat insulation fabric as the main body has heat insulation properties. The surface is covered with a microporous film, which can also improve the effective blocking of the heat insulation layer against heat radiation and heat conduction. At the same time, the microporous film also has certain air permeability, echoing with the moisture absorption and sweat discharge layer of the inner layer to improve the moisture absorption and sweat discharge effect of the inner layer.
