Description

{FABRIC FOR SPECIAL CLOTHES} < / RTI > < RTI ID = 0.0 >

[0001] The present invention relates to a special wearing fabric of a fire fighting suit and a chemical protective suit, and more particularly, to a special suit for a fire suit and a chemical protective suit which can safely protect a user who handles a fire and a chemical from a danger.

Generally, fire extinguishers and chemical protective clothing protect workers' bodies from strong heat from fire or from chemicals that are harmful to human bodies and water vapor that continues to burst from the hose.

Such fire-extinguishers are made of heat-resistant fibers and are made up of outerwear or lining which are overlapped or adhered to each other. In some cases, an intermediate feeling is added between the outerwear and the lining.

The prior art of such a fire fighting suit is Korean Patent Registration No. 10-0930511 proposed by the applicant of the present application and entitled "Lining of a special fire-fighting lining and its special lining" (prior art 1). As shown in FIG. 1, the outer garment according to the prior art 1 is composed of a heat-dissipating hood 1, a heat-dissipating work cloth 10, a heat-dissipating glove 2 and a heat-dissipating shoe 3, A middle feeling 10b, and a lining 10c.

The outer cloth 10a is composed of a heat-resistant cloth 12 on which aluminum 11 is deposited as shown in the enlarged view, and reflects fire or radiant heat by the aluminum 11. [ The intermediate layer 10b is composed of a nonwoven fabric 13 having a waterproofing membrane 14 attached thereon and is waterproofed by the membrane 14 while dispersing the heat by the nonwoven fabric 13.

The lining 10c is made of a flame retardant material 16 made of flame retardant fibers such as aromatic polyamide fibers (also referred to as " aromatic polyamide fibers ") and subjected to a beveling treatment on the felt fabric 15, 15 and the flame retardant material 16.

However, the fire fighting garment having the above-described structure has the outerwear 10a, the middle feeling 10b and the lining 10c, the heat resistant fabric 12 having the aluminum 11 deposited thereon, the nonwoven fabric 13 having the membrane 14 attached thereto, There is a problem that the weight of the cloth is excessively increased and the thickness of the cloth becomes excessively thick because it is composed of the raw material 15 and the raw material 16 of the flame retardant material and therefore the worker can not smoothly carry out the work.

In addition, the feeling of wearing is reduced due to the thickness of the felt fabric 15 constituting the lining 10c, and the problem that the membrane 14 is worn or damaged by friction with the felt fabric 15 of the lining cloth 10c during operation .

On the other hand, chemical protective clothing is made of fabric with chemical resistance and is used in the CBR area or industrial sites contaminated with hazardous chemicals. Such chemical protective clothing is made of a fabric such as aramid or nylon coated with a protective layer excellent in heat resistance and chemical resistance.

Prior art of such a chemical protective clothing is disclosed in Korean Patent Registration No. 10-0929207, filed by the present applicant and filed by the applicant, "Chemical protective clothing fabrics and chemical protective clothing" (prior art 2).

As shown in Fig. 2, the chemical protective clothing fabric of the prior art 2 includes a textile fabric A, a chloroprene rubber layer B, a butyl rubber layer F, and a fluoropolymer B, which are sequentially laminated on one surface of the fabric A A layer D and a chloroprene rubber layer B, a fluoropolymer layer D and a chemical protective film E which are sequentially laminated on the back surface of the fabric A.

However, since the chemical protective clothing fabric of the prior art 2 as described above has a complicated structure due to the lamination of the chloroprene rubber layers (B) on both sides of the fabric A, the manufacturing process is complicated and the material cost is large. Since the rubber layer is provided on both sides, there is a problem that the chemical protective clothing is too heavy.

Particularly, the chemical protective clothing fabric according to the prior art 2 has a problem that the film layer E is formed in a flat state, so that it is easily torn by the impact, Chemicals may penetrate through the gap.

At this time, the first layer 100, the second layer 200, and the third layer 300 are coated with an adhesive in any one of gravure, dot, and mesh methods, A second layer 200 is attached, and a third layer 300 is attached to one side of the second layer 200.

In addition, the first layer 100 is made of a material having excellent heat resistance to heat at a high temperature. The first layer 100 is made of, for example, aramid fibers. Such an aramid fiber may be any one of a meta-aramid fiber or a para-aramid fiber as the aromatic polyamide fiber.

As described above, the aramid fibers forming the first layer 100 are not only excellent in heat resistance and flame retardancy, but also have a tensile strength that does not increase even if a force is applied because a thin yarn having a thickness of about 5 mm can withstand a load of 2 tons.

The first layer 100 may be a meta-aramid fiber or a para-aramid fiber as described above. In some cases, the first layer 100 may be blended with polybenzimidazole (PBI) 40% and para-aramid 60%.

PBI is a fiber that has flame resistance and thermal stability in the fiber itself. It does not shrink or break even when exposed to flame and high temperature, and it does not transmit heat to the inner layer.

Thus, when the first layer 100 is blended with 40% of PBI and 60% of para-aramid fiber and used as a outerwear of a special garment such as a fire suit or chemical protective suit, a firefighter can withstand a longer time It has activity.

That is, either one of the two fabrics 310 and 320 is a mesh fabric, or one of two fabrics 310 and 320 is a mesh fabric.

Further, when the two fabrics 310 and 320 are made of mesh fabrics, the holes formed in each of the two mesh fabrics may have different sizes or may be formed to have the same size as each other.

Also, as shown in FIG. 10, the mesh may be formed with a hollow P for providing pores in the end surface thereof. When a hollow is formed in the mesh fabric, the breathability and the drying force are more excellent.

Such a hollow P may be formed on both of the two mesh fabrics as shown in FIG. 10, but in some cases, it may be formed on only one of the two mesh fabrics.

The fabrics 310 and 320 provided on both sides of the filament yarn 330 may be made of a heat-resistant or flame-retardant fabric such as aramid fiber or para-aramid fiber, polybenzimidazole (PBI) Para-Aramid).

The pile yarn 330 connecting the two ends 310 and 320 moves toward the opposite fabric when an external force is applied to one of the ends 310 and 320. When the external force is lost, So that the elastic force can be restored.

As described above, the special-purpose fabric of the present invention comprises a multi-layer structure of a first layer 100 made of aramid fibers, a second layer 200 made of Teflon-based resin, and a third layer 300 made of a three- So that the wearer can be safely protected even at a high temperature and has excellent activity.

In addition, the present invention can minimize the fatigue of the wearer due to the smooth and excellent drying performance, can block the water penetrated from the outside, and can smoothly discharge the sweat inside the body, so that the wearer can work in a pleasant condition, .

In addition, the third layer 300 of the present invention is made of a three-dimensional air mesh to reduce the weight and improve the activity of the wearer. The cushioning force of the three-dimensional air mesh not only provides excellent wearing comfort but also has excellent air permeability, Even if it is wet.
