Abstract

The utility model relates to wet guiding thermal insulating compound down, which comprises five layers, wherein, the first layer is knitted or woven cloth, the second layer is pile, the third layer is synthetic films, the forth layer is pile, and the fifth layer is knitted or woven cloth. The layers of pile are used as intermediate bodies, and two layers or one layer of knitted or woven cloth are bonded and compounded with the layers of pile to form the wet guiding thermal insulating compound down. The utility model can replace the existing thermal insulation materials, and can be applied for the manufacture of various thermal insulation materials.

Description

Wet-guiding insulating multiple down

It is heat insulating material formed that the utility model relates to a kind of light textile, especially provides the superconduction of the compound or single face of a kind of double face binding bonding compounded fabric wet high heat insulating material formed to society.

At present, known heat insulating material formed row are as natural fiber materials such as cotton, silk flosssilk wadding, wool, camel's hair, eider downs; Man-made fibre materials such as gum sprayed cotton, polyacrylonitrile fibre, long filament dacron cotton, metal wool.These materials all have certain thermal property, but their weak point, the hygroscopicity that has warming rate poor, that the have coefficient of variation low, that have tensile strength big, that have gas permeability washing shrinkage bad, that have not enough, that have is too high, yet these heat insulating material formed forms just are used for making various warming products with the form of packing material, exist inconvenience aspect manufacture craft.

The purpose of this utility model is to overcome existing heat insulating material formed deficiency, and a kind of wet compound suede of warming bonding of leading is provided.

The purpose of this utility model is achieved in that its layer of structure is: ground floor is knitting or woven cloth, and the second layer is a lint, and the 3rd layer is built up membrane, and the 4th layer is lint, and layer 5 is knitting or woven cloth.

The lint layer of intermediate is that two-sided or single face needled flocking is on 0.4～1.2 the synthesis of thin-film layer at thickness with lint.

Synthesis of thin-film layer adopts materials such as high pressure PEF, Bai Shan to make.

The lint of the lint layer of intermediate adopts staple fibre, synthetic fibers.

Knitting or the woven cloth of two layers or one deck adopts staple fibre, synthetic fibers and natural fiber.

Boning in the incorporate compound suede of compound composition, comprise three above levels at least, can be that two-sided cloth bonding is compound, can be that single face cloth bonding is compound.

The utility model, owing to adopt such scheme, with the lint layer as intermediate, with two-layer or one deck is knitting or woven cloth is glued compound, can produce the wet high warming integrated compound suede of superconduction, directly make various insulation garments, replaced existing heat insulating material formed clothing pattern as filler by cutting, sewing.This product is tested through China Textile University, and its performance indications are as follows:

Lead moist permeability	Warming rate	Fracture strength N	The coefficient of variation	Gas permeability	1/M2.S
						Be higher than wool 50%	61%	142	19%	240

It is wet high warming to the utlity model has superconduction, also have tensile strength, gas permeability, regain, elastic force, a pliability etc. to be brilliance, and be that any in the past textile material is incomparable.This provides a kind of novel practical, advanced material reliably for undoubtedly human dress.

For introducing the utility model in detail, be described further below in conjunction with drawings and Examples.

Accompanying drawing 1 is a structural representation of the present utility model.

1. knitting or woven clothes among the figure.2. lint.3. built up membrane.4. lint.5. knitting or woven cloth.

Embodiment 1, as shown in Figure 1, select two layers of knitting or woven cloth 1 for use, 5, lint layer 2 with intermediate, 3,4, the lining that the bonding complex group becomes one, it is softening to adopt chemical fibre lint and/or artificial lint to carry out combing by carding machinery earlier, put on 0.4～1.2 thick synthesis of thin-film layer 3 through the shop even shakedown of hair device then, carry out acupuncture again, using up and down reciprocatingly, acupuncture is implanted in thin layer to lint, form needling process for the first time, 2,3 combine, then carry out the acupuncture second time again, 2,3,4 combine, and become the lint layer of intermediate, 2,3,4 lint layer is sent into composite machine, through to the netted spray glue of the single face of lint layer, carry knitting or woven cloth 1 or 5 with mechanical synchronization simultaneously, arrangement typing bonding back generates the compound suede of single face, again the compound suede of compound good single face that bonds is for the first time turned over and repeat once to bond compound, just produced the compound suede of double face binding.The compound suede of Xing Chenging becomes the hygroscopicity that can directly use strong, warming rate height, the novel fabric that tensile strength is good or lining lining thus.
