Most woollen blanket belongs to inflammable or combustible material, and because textile is not fire-retardant, to account for fire incident ratio increasing for fire that is that cause.No matter conventional woollen blanket textile material is animal origin or chemical fibre such as polyster fibre, acrylic fiber etc., although it has, intensity is high, good springiness, wrinkle resistance strong, dimensionally stable, wearability are good, stable chemical performance, heat resistance and the performance such as against weather is excellent, but itself be a kind of combustible fibre, therefore make it be restricted in the application in a lot of field.In order to improve its range of application, must make it have the effect of flame resistance, therefore, the research of woollen blanket flame-retarded technology becomes the problem that academia and industrial quarters are extremely paid close attention to.
In recent years, the development of flame-retarded technology have passed through fabrics flame resistance Final finishing in earlier stage, Compound spinning and crosslinking technology, develops into and adopts now halogen system and phosphorus system copolyester fiber as fire proofing.Fabrics flame resistance Final finishing, through washing and the increase along with service time, the fire-retardant molecule infiltrated in fabric fibre volatilizees gradually, causes anti-flammability to reduce.Although halogen flame flame retardant effect meets the requirements, but self there is a series of defect, as easily released irritant and corrosive hydrogen halide when burning, and produce poisonous many bromos and furans and many bromos dibenzo pentane when Pintsch process and burning, safety of life and property is constituted a threat to.Therefore, in prior art, mostly the developing direction of fire-retardant polyester fibre is to adopt phosphorus based polyester flame-retardant complex fiber merely, but the above-mentioned flame retardant effect of phosphorus based polyester flame-retardant complex fiber that only adopts of the prior art is still bad, also has the space of improving.
utility model content:
In order to solve the problem, the utility model provides a kind of heat-insulating and fire-proof woollen blanket with sandwich construction, is vertically disposed with plant fiber layer and animal origin layer at flame-retardant layer, thus has excellent gas permeability and warmth retention property and be incubated flame resistance.
The technical scheme that heat-insulating and fire-proof woollen blanket of the present utility model adopts is:
A kind of heat-insulating and fire-proof woollen blanket, it is made up of the plant fiber layer arranged from top to bottom, the first flame-retardant layer, glass layer, the second flame-retardant layer and animal origin layer, described first flame-retardant layer and the second flame-retardant layer are organophosphor system flame retardant polyester fiber, its raw material is 50:35:10:5 by rutgers, butanediol, hydroxymethyl phenyl phosphinic acids and triphenyl phosphate according to weight proportion and adopts warp knitting technology to make, second flame-retardant layer is near animal origin layer, and its thickness is greater than the thickness of the first flame-retardant layer.
Further, described plant fiber layer is cotton, numb, bamboo fibre.
Further, described animal origin layer is the scared of animal and fine hair, the eider down of bird and feather and silk.
The beneficial effects of the utility model are as follows:
1. as the plant fiber layer on top layer and animal origin layer, there is wettability power strong, the advantage that good permeability, warmth retention property are good.
2., as flame-retardant layer and the glass layer in intermediate layer, there is good heat insulating effect.
accompanying drawing illustrates:
