Problems solved by technology

However, the protected personnel still have a high probability of being burned, and the arc protection clothing still has a certain degree of shrinkage, especially in the chest, back and limbs, so these parts are more likely to be burned, and people need to find better solutions to reduce these damages. injury, or gain more protection time

Embodiment 1

[0033] like figure 1 As shown, the arc-proof clothing includes an arc-proof surface layer 1, and is characterized in that it also includes two layers of comfort layers 3, 4 positioned inside the arc-proof surface layer 1, between the arc-proof surface layer 1 and the comfort layer 3, There is also a support layer 2 with protrusions on both sides of one layer of fabric. like figure 2 As shown, the arc-proof chest, back and limbs include one more support layer 2 than other positions, and the extra layer is arranged between the comfort layers 3 and 4 .

[0034] The support layer is a mesh structure, and the intersection part of the mesh is knot-shaped, and it is sewn between the anti-arc surface layer and the comfort layer through flame-retardant threads, such as image 3 and 4 Shown are two different support layer structures.

[0035] like Figure 5 As shown, 1, 2, 3, and 4 in the figure indicate the warp and weft yarns of the outer layer, and I, II, III, and IV indicate t...

Embodiment 2

[0043] The arc protection clothing described in the above-mentioned embodiment 1 is all the same except that the structure of the comfort layer 4 is different. In the present embodiment, the comfort layer 4 includes a front layer 4.1 and a back layer 4.2, the front layer and the back layer both include fabric one and fabric two, the back side of fabric one is fabric two, the back side of fabric two is fabric one, and the back side of fabric two is fabric one. The high-temperature carbonization shrinkage of fibers in fabric 1 and fabric 2 is different. When encountering an arc explosion, the side with a small heat shrinkage will bulge. Since there are two different yarns on the front and back, each side will have a bulge, such as Figure 7 As shown, this will create a larger thermal insulation space than the traditional fabric with only one side raised, so as to achieve a better thermal insulation protection effect.

Embodiment 3

[0045] The arc-proof clothing described in the above-mentioned embodiment 1 is the same except that the support layer is set into the arc-proof surface layer and the connection mode of the comfort layer is different. The present embodiment adopts the non-continuous, Non-tight connection, the total thickness of the air layer formed between the layers is 6-14mm. Under the condition that the ambient temperature is 25°C, the skin temperature is 33°C, and the wind speed is 0.1m / s, the experiment shows that if Figure 8 As shown, the influence of the thickness of the air layer under the clothes on the total sensible heat and the heat flux of each component: when the thickness of the air layer is less than 16 mm, the sensible heat transfer through the air layer under the clothes is heat conduction and radiation. As the temperature increases, the conduction heat gradually decreases, while the radiant heat gradually increases. This is because radiant heat has nothing to do with the th...

Abstract

The invention discloses an arc-protective garment. The arc-protective garment comprises an arc-protective surface layer and is characterized by comprising a plurality of comfortable layers located on the inner side of the arc-protective surface layer, and a supporting layer with bulges on two surfaces of at least one layer of fabric is arranged between the arc-protective surface layer and one comfortable layer. According to the arc-protective garment, the interlayer configuration structure comprising the arc-protective surface layer, the supporting layer and the comfortable layers is ingenious, air layers under the garment are ensured to be enough thick, the impact resistance of the fabric can be improved at the moment of arc explosion, the high-temperature harm of arc can be greatly reduced, escape time is won, burns are avoided or the burn degree is reduced, the wearing comfort of the arc-protective garment is greatly improved due to the adoption of multiple air layers, the practicability is extremely high, and the arc-protective garment has good social benefits and is worth popularization.

Description

technical field [0001] The invention relates to a functional fabric, in particular to an anti-arc clothing. Background technique [0002] Once arc-proof overalls come into contact with arc flames or heat, the internal high-strength and low-stretch bulletproof fibers will automatically and rapidly expand, thereby making the fabric thicker and denser, forming a protective barrier for the human body. The protective effect of arc-proof work clothes has the characteristics of heat resistance, flame retardancy, non-combustibility, non-melting, and H-level electrical insulation, such as permanent fire prevention and insulation. When an arc explosion occurs, this high-tech material will expand rapidly and the fabric will be carbonized, which will increase the density and thicken the structure of the arc protection suit, and quickly form a protective layer to resist the thermal effect of the arc, causing human skin to be damaged by contact with the arc heat. Minimization reduces bur...
