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.
