摘要

Multilayer sheet material for fireproof protective clothing has a double external layer comprising a layer which undergoes shrinkage when exposed to heat, with interlayer pockets formed by intermittently linking selected threads in the two layers. Complex multilayer sheet material for protective clothing, especially for fire fighters, with an external fabric/thermal barrier comprising first and second layers, is made by weaving or knitting so as to form a double-faced, superimposed structure (1, 2) bound together intermittently to form pockets, with one layer showing shrinkage when heated and the connection between the layers being formed by intermittent linkage of a selection of threads to form these pockets.
