Problems solved by technology

The current composite fabrics for firefighters' protective clothing are not ideal in general, especially the weight and thickness of the fabrics and the properties of the fabrics such as flame retardant, heat insulation, waterproof and breathable have not yet reached a good unity
[0003] There have been similar textile materials for firefighting clothing, which caused excessive heat accumulation due to ineffective heat insulation, causing firefighters to suffocate at the scene due to overheating, and the production cost remained high

Abstract

The invention discloses a lightweight compound fabric used for firemen protection-suit during the fire-extinguishing process. The invention is composed of the following four layers in turn: a flame-retarding layer, a waterproofed breathable layer, a thermal-insulating layer and a comfortable layer, between which, the methods like quilting are adopted for combination, wherein, the thermal-insulating layer is a non-woven fabric heat-insulating felt which is composed of lame-retarding fiber, flame-retarding viscose fiber and high-intensity fiber. The compound fabric of the invention is light and thin, thermal-insulating and breathable. The result of the detection shows that the weigh of the whole protection suit is 22% lighter than the national standard of 3.5kg, but the total protective performance is 21.4% higher than the national standard of 28.

Description

technical field [0001] The invention relates to a composite fabric, in particular to a composite fabric used for firefighters' fire-fighting and protective clothing, and in particular to a heat-insulating layer in the composite fabric used for firefighters' fire-extinguishing and protective clothing. Background technique [0002] In developed countries such as the United States, Europe, and Japan, the field of protective clothing is undergoing a technological innovation due to realistic needs. The basic common point of developing new thermal protective clothing materials in these developed countries is: make full use of the latest high-performance fibers in the world for scientific and reasonable screening and combination, and continuously develop new mixed fibers and composite materials on this basis. Materials and various heat protective clothing adapted to different places to better protect the life safety of ambulance personnel. The Chinese patent CN244688Y that the app...
