Multi-layer weft-knitted spacer fabric for fire-fighting heat-insulating clothes

Abstract

The invention relates to a multi-layer weft-knitted spacer fabric for fire-fighting heat-insulating clothes. The multi-layer weft-knitted spacer fabric comprises a microporous aluminum foil, a reflecting film adhesion layer adhered to the microporous aluminum foil, a flame-retardant heat-insulating layer, a spacer layer, a moisture absorption conduction layer and a comfortable layer from outside to inside, wherein the reflecting film adhesion layer, the flame-retardant heat-insulating layer, the spacer layer, the moisture absorption conduction layer and the comfortable layer are formed by one-time weaving through a double-sided circular knitting machine, the reflecting film adhesion layer and the flame-retardant heat-insulating layer adopt a plating weaving mode, the moisture absorption conduction layer and the comfortable layer adopt a plating weaving mode, the spacer layer is connected to the two adjacent layers through a tucking mode, the spacer layer is made of glass fiber filaments, the moisture absorption conduction layer is made of aramid fiber and flame-retardant viscose blended staple fiber yarn, and the comfortable layer is made of flame-retardant viscose rotor spun staple fiber yarn. According to the invention, the multi-layer weft-knitted spacer fabric has a multi-layer structure, the targeted fibers are selected and woven, and the functions of each layer are completely achieved, so that the protective clothing is light, high in heat insulation and protection performance, capable of achieving the one-way wet conduction effect, and improves the comfort of wearers.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a multi-layer weft-knitted spacer fabric used for fire-fighting and heat-insulating clothing. Background technique [0002] Fire-fighting thermal insulation clothing is clothing that provides thermal insulation protection for firefighters or other workers working in high-temperature places. It is generally made of a composite material of flame-retardant fiber fabric and vacuum aluminized film, which requires light specific gravity, high strength, flame retardancy, high temperature resistance, heat radiation resistance, waterproof, wear resistance, folding resistance, and It is harmless to the human body, etc. Wearing this clothing can effectively protect firefighters and workers in high-temperature places from being burned by intense heat, flames, and steam even if they are close to the heat source. The importance of firefighting clothing is that it directly faces the harsh and...

Problems solved by technology

[0003] The basic function of fire-fighting thermal insulation clothing is to block and delay the heat in the fire environment from passing through the thermal insulation clothing to cause harm to firefighters. The thickness or weight of the thermal insulation fabric is closely related to the protective effect. The heavier the protective clothing, the better the protective effect. Good, but too heavy protective clothing will seriously affect the efficiency and comfort of firefighters. Therefore, improving the protection ability, reducing the weight of protective fabrics, and improving comfort are the eternal directions for the research and development of fire insulation clothing fabrics
