Special clothing fabrics for fire-fighting suits and chemical protective suits and special fabrics made of the fabrics Special clothing

The invention relates to a special clothing fabric for a fire service suit and a chemical protective suit, in particular to a special clothing fabric for a fire service suit and a chemical protective suit for safely protecting a user who is involved in fire fighting and chemical exposure from danger.

Generally speaking, fire-fighting suits and chemical protective suits protect the body of workers from the strong heat in the fire or the continuous spraying of water vapor in the hose and chemical substances harmful to the human body.

The fire service is made of heat-resistant fibers and is composed of an outer fabric or lining which is overlapped or adhered to each other, and is formed by adding an intermediate fabric between the outer fabric or the lining as the case arises.

The prior art of such a fire service suit, the lining of the special service for fire extinguishing and the special service made therefrom, in the Korean Patent Registration No. 10-0930511 filed by the applicant of the present application (Prior Art 1) There are records in it. The fire service according to the prior art 1 is composed of a heat-resistant headgear 1, a heat-resistant overalls 10, a heat-resistant glove 2, and a heat-resistant shoe as shown in Fig. 1, and is enlarged by the outer fabric 10a, the intermediate fabric 10b, and the inner liner 10c. .

The outer fabric 10a is composed of a heat-resistant fabric 12 deposited of aluminum 11 as shown in an enlarged view, and reflects fire or radiant heat according to the aluminum 11. The intermediate fabric 10b is composed of a non-woven fabric 13 to which the waterproof separator 14 is adhered, and is waterproofed by the separator 14 while dispersing heat according to the nonwoven fabric 13.

The inner liner 10c is quilted on the felt fabric 15, and is composed of a flame-retardant material 16 made of flame retardant fibers similar to aromatic polyamide fibers (also called aromatic nylon), and passed through the felt fabric 15 and Incombustible material 16 for insulation.

However, the fire service constructed as described above is composed of the outer fabric 10a and the intermediate fabric 10b and the inner liner 10c, and the heat-resistant fabric 12 deposited by the aluminum 11 and the non-woven fabric 13, the felt fabric 15 and the flame-retardant material fabric 16 adhered by the separator 14. This not only excessively increases the weight of the garment but also has a problem that the thickness of the garment is too thick, and therefore, the worker cannot flexibly carry out the work.

Further, due to the thickness of the felt fabric 15 constituting the inner liner 10c, not only the feeling of use is lowered, but also the problem that the diaphragm 14 and the felt fabric 15 of the inner liner 10c directly rub against each other during work causes abrasion or damage.

In addition, chemical protective clothing is manufactured from chemically resistant fabrics and used in the original biochemical area or in industrial sites contaminated by hazardous chemicals. This chemical protective suit is made of a material similar to a polyamide or nylon surface covered by a protective layer with excellent heat resistance and chemical resistance.
