Thermal insulation layer: weaved by the blended rear employing conventional method of the component of following weight parts and form: 10-30 part hollow three-dimensional crimp polyester staple, one of following fiber of 70-90 part: fire-retardant vinylon, pre-oxidized fibers;
Flame contacting layer, the yarn weaving be spun into by flame-resistant terylene, fire-retardant nylon, fire-retardant viscose, Vinyon N, Ju Fang oxadiazole fiber, PSA fiber, aramid fiber 1313, Fanglun l414 and one or more fibers of pre-oxidized fibers forms; Be 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 be selected from PSA fiber, aramid fiber 1313 and Fanglun l414 one or more;
The fiber number of described hollow three-dimensional crimp polyester staple is 2-10D;
Further preferred, describedly to be formed by 10-20 weight portion flame-resistant terylene, 10-20 weight portion fire-retardant nylon and blended the weaving of 60-80 weight portion Fanglun l414 with people's contact layer;
Described is 150-300g/m with the grammes per square metre of people's contact layer
2, can be plain weave, twill, satin weave, square equality structure;
The grammes per square metre of described thermal insulation layer is 70-300g/m
2, can be the structures such as the flocculus made by techniques such as water thorn, acupuncture, gum sprayed cottons;
The grammes per square metre of described flame contacting layer is 200-300g/m
2, can be plain weave, twill, satin weave, square equality structure; The number of described yarn is that 5-40 props up;
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 that add fire retardant mixing in melt spinning forward direction melt after, conveniently wet spinning spinning process is shaping obtains respectively;
The mass percent that described fire retardant accounts for described melt is 3-10%;
Described fire retardant, is selected from one or more the mixture in N-methylol-3-(dimethoxy phosphono) propionamide, two (4-carboxyl phenyl) phenyl phosphine oxide.
Preferably, described fire retardant is made up of following components in mass portion: N-methylol-3-(dimethoxy phosphono) propionamide 20-40 part, two (4-carboxyl phenyl) phenyl phosphine oxide 30-50 part.
