Aramid waterproof flame-retardant base fabric

Abstract

The invention discloses an aramid waterproof flame-retardant base fabric. The aramid waterproof flame-retardant base fabric comprises a PE film, wherein a flame-retardant glue layer is connected to one side of the PE film; one side, away from the side of the PE film, of the flame-retardant glue layer is connected to a warp and weft composite layer; a plurality of composite warp and composite weftwhich are mutually perpendicular are arranged in the warp and weft composite layer; the exteriors of the composite warp and the composite weft are provided with a round of composite layer covered edge; the connecting parts of the composite warp and the composite weft are connected to cross reinforcing ends; and aramid yarn cores are arranged in the composite warp and the composite weft of the warpand weft composite layer, revolving threads are wound on the outside of the aramid yarn cores, and one sides of the composite warp and the composite weft are connected to flame-retardant weaving meshes through the cross reinforcing end, so that the structural strength of the base fabric is greatly improved, the protective performance of the base fabric is also improved, and the PE film at the bottom plays a waterproof role in normal use, thereby improving the use effect of the base fabric. The aramid waterproof flame-retardant base fabric has a simple structure and high practical use rate.

Description

technical field [0001] The invention relates to a base cloth, in particular to an aramid waterproof and flame-resistant base cloth, which belongs to the technical field of industrial textiles. Background technique [0002] The full name of aramid is "polyphenylene phthalamide". It is a new type of high-tech synthetic fiber with excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. Its strength is stronger than that of steel wire. 5~6 times that of steel wire or glass fiber, the modulus is 2~3 times that of steel wire or glass fiber, the toughness is 2 times that of steel wire, and the weight is only about 1 / 5 of steel wire. It does not decompose or melt at a temperature of 560 degrees. It has good insulation and anti-aging performance, and has a long life cycle. The discovery of aramid fiber is considered to be a very important historical process in the material industry. However, among som...

Problems solved by technology

The discovery of aramid fiber is considered to be a very important historical process in the material industry. However, among some flame-retardant base fabrics, the existing base fabrics have poor flame retardancy and short service life. If they are used at high temperatures for a long time, they are prone to deformation. , the problem of increasing gaps in the fabric, for this we propose a kind of aramid waterproof and flame-retardant base fabric
