Flame-retardant hook-and-loop fastener for fire-extinguishing protective clothing of firefighter and manufacturing method of flame-retardant hook-and-loop fastener

Abstract

The invention relates to the field of fire fighting, in particular to a flame-retardant hook-and-loop fastener for fire-extinguishing protective clothing of firefighters and a manufacturing method of the flame-retardant hook-and-loop fastener. According to the application, by utilizing the characteristics that polyphenylene sulfide is resistant to high temperature of 260 DEG C, has a permanent flame-retardant function and is free of molten drops and not carbonized during combustion, polyphenylene sulfide fibers are taken as a main body material, polyester fibers are added, interweaving is performed to prepare a hook-and-loop fastener hook surface and a hook-and-loop fastener loop surface, then prepared male and female buckles are soaked with a flame retardant, and dewatering and drying treatment is performed to obtain a further flame-retardant effect. Meanwhile, by utilizing the characteristics that silica gel has no melting point and can be carbonized at about 400 DEG C, liquid silica gel is taken as a main body material, flame-retardant powder is added, mixing and stirring are performed uniformly, a mixture coats the backs of the male buckle and the female buckle, and baking is performed to form a solid flame-retardant silica gel layer. Therefore, the afterflame time of the gummed male buckle and the gummed female buckle does not exceed 2 seconds during combustion, the molten drops and the carbonization are avoided, the standard requirements of 'firefighter fire-extinguishing protective clothing XF10-2014' are met, and the flame-retardant hook-and-loop fastener is widely applied to the field of fire fighting.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment accessories, in particular to a flame-retardant Velcro for firefighters' fire-fighting protective clothing and a manufacturing method thereof. Background technique [0002] The production cost of the existing flame-retardant aramid Velcro surface is high, and due to technological reasons, the hook warp on the aramid tissue of the flame-retardant aramid Velcro hook surface is still replaced by nylon material, making the flame-retardant aramid Velcro The temperature resistance of the hook surface is far lower than 260 degrees Celsius, and it will melt when burning, which does not meet the standard requirements of "Firefighter Fire Fighting Protective Clothing (GA10) XF10-2014". Contents of the invention [0003] In view of the deficiencies in the prior art, one of the purposes of the present invention is to provide a fire-resistant Velcro for firefighters' fire-fighting protective clothing, ...
