Thermal insulation layer: formed using conventional method weaving after being blended by following components in parts by weight: the three-dimensional volume of 10-30 part hollow
Bent polyester staple fiber, one of following fiber of 70-90 part: fire-retardant vinylon, pre-oxidized fibers；
Flame contacting layer, by flame-resistant terylene, fire-retardant nylon, fire-retardant viscose, Vinyon N, poly- virtue diazole fiber, PSA fiber, aramid fiber
1313rd, the yarn weaving that Fanglun l414 and one or more fiber of pre-oxidized fibers are spun into forms；It is preferably fire-retardant viscose；
Aluminium foil layer.
Preferably,
Described abrasion resistant fire blocking fiber is selected from flame-resistant terylene, fire-retardant nylon or the mixture of the two；
Described fire-retardant fireproof fiber is selected from one or more of PSA fiber, aramid fiber 1313 and Fanglun l414；
The fiber number of described hollow three-dimensional crimp polyester staple is 2-10d；
It is further preferred that described and people's contact layer is by 10-20 weight portion flame-resistant terylene, 10-20 weight portion fire-retardant nylon
Form with the blending weaving of 60-80 weight portion Fanglun l414；
The described grammes per square metre with people's contact layer is 150-300g/m2, can be plain weave, twill, satin weave, square equality structure；
The grammes per square metre of described thermal insulation layer is 70-300g/m2, can be the wadding made by techniques such as spun lacing, acupuncture, gum sprayed cottons
The structures such as piece；
The grammes per square metre of described flame contacting layer is 200-300g/m2, can be plain weave, twill, satin weave, square equality structure；Described yarn
The number of line props up for 5-40；
The thickness of described aluminium foil layer is 0.05-0.5mm.
Preferably, in flame contacting layer, described anti-flaming viscose, flame-resistant terylene, fire-retardant nylon are to molten respectively before melt spinning
After internal addition fire retardant mixing, obtain according to conventional wet lay spinning spinning process molding；
