Technical Field

[0001] The utility model relates to a low-temperature resistant coated fabric, belonging to coated fabrics. Background Art

[0002] Accidents and disasters are one of the main threats to public safety. In order to deal with accidents and disasters, rescue workers need to wear protective clothing to deal with unknown hazards such as dangerous chemicals or fires. Protective clothing is usually made of fabrics plus coatings, but the connection strength of the coating of the fabrics used in ordinary protective clothing will decrease in low temperature environments, which will reduce the protective effect of the protective clothing fabric. How to prepare a low-temperature resistant coated fabric has become a problem to be solved. Utility Model Content

[0005] The utility model relates to a low-temperature resistant coating fabric, comprising a composite base fabric layer, a polyhalogenated olefin film, a barrier fabric layer and a flame-retardant nylon fabric layer; a flame-retardant coating is provided on the side of the base fabric layer away from the polyhalogenated olefin film;

[0006] The base fabric layer is interwoven with aramid polytetrafluoroethylene core-spun yarn, the aramid polytetrafluoroethylene core-spun yarn includes core yarn and a covering fiber layer, the core yarn includes polytetrafluoroethylene split film filaments, and the covering fiber layer is aramid 1313 fiber; the surface of the base fabric layer on one side away from the polyhalogenated olefin film has fluff formed by raising; the fluff extends to the inside of the flame retardant coating.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the barrier fabric layer is a graphene / carbon fiber composite aerogel layer.

[0008] On the basis of the above solution and as a preferred solution of the above solution: the barrier fabric layer is composed of a polyimide aerogel fiber layer.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: a planar three-dimensional fabric layer is arranged between the barrier fabric layer and the flame-retardant nylon fabric layer; the planar three-dimensional fabric is interwoven with polyphenylene sulfide fiber yarns.

[0010] On the basis of the above scheme and as a preferred scheme of the above scheme: the polyhaloolefin membrane is a polyvinyl chloride membrane or a polytetrafluoroethylene membrane.

[0011] On the basis of the above scheme and as a preferred scheme of the above scheme: the core yarn also includes glass fiber yarn twisted with polytetrafluoroethylene split film filaments.

[0012] The beneficial effects of the utility model are as follows: the low-temperature resistant coating fabric of the utility model has the fluff formed by raising the base fabric layer extending into the flame retardant coating, so that the base fabric layer and the flame retardant coating are more firmly combined and are not easy to fall off in a low-temperature environment. In addition, the polytetrafluoroethylene split film filaments and aramid fibers used can improve the dimensional stability and flame retardant effect of the base fabric layer.
