Description

It is easy to the double-layer fabric thin film that human body water vapour is discharged
Technical field
The present invention relates to a kind of double-layer fabric thin film being easy to the discharge of human body water vapour, belong to technical field of textile fabric.
Background technology
Polyurethane fabric is a class artificial leather shell material, has the texture of corium, so the artificial leather that is otherwise known as.It is not only tied Real durable, and because synthetic technology maturation price is the cheapest, be widely used at garment industry.The PU face of prior art Material is the fabric of single PU structure sheaf, and owing to PU fabric resistance to water is poor, thus the clothing of PU fabric typically can not be washed, Dry-cleaning can only be used, improve use cost.PU fabric breathability is poor, and reduce when PU fabric clothes is worn is comfortable Degree, such as, perspire when wearing and cannot discharge.In addition, the wearability of PU fabric is poor and surface be full of cracks occurs, comes off Phenomenon.
And polytetrafluoroethylene film, owing to its special microcellular structure (in netted) makes it have pore type polyurethane film The wind and water preventing that can not have, water vapour permeability, be better than traditional microporous polyurethane thin film, but its shortcoming it is also clear that, this Kind of its elasticity of material is substantially zeroed, the most this thin-film material either with the recombination process of fabric in or in high intensity All can not well adapt to fabric during strenuous exercise and stretch the thin film damage that brought, easily cause water resistance and its with The decline of the bond properties of fabric.
Summary of the invention
It is an object of the present invention to provide a kind of double-layer fabric thin film being easy to the discharge of human body water vapour, this double-layer fabric thin film carries High elastic and adaptability, also avoids due to the dust in the empty vapour of pore type polytetrafluoroethylene film layer absorption, salt in perspiration Part, the material such as oils and fats cosmetics and detergent, it is achieved that keep stable waterproof for a long time and perspire vapour performance, having simultaneously Have high intensity, do not absorb water, anti-wear performance.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of dual-layer face being easy to the discharge of human body water vapour Material thin film, including pore type polyurethane film, polytetrafluoroethylene film, described pore type polyurethane film, politef are thin Bonded by adhesive layer between film；
Described pore type polyurethane film is scratched in silicon oil release paper and successively 80 ~ 150 degree of temperature by prefabricated polyurethane slurry The baking oven baking of degree gradient, is cooled to room temperature again after reaching 150 degree and being incubated and obtains；
Described prefabricated polyurethane slurry is composed of the following components: polyurethane resin 100 parts, dimethylformamide 25 parts, toluene 35 Part, butanone 15 parts, microspheres 9 parts, Isosorbide-5-Nitrae one butanediol 2.2 parts, polyacrylamide 1.8 parts, acrylate 0.4 part, organic Silicone emulsion 0.3 part.
The technical scheme improved further in technique scheme is as follows:
As preferably, the volume of described polytetrafluoroethylene film Hole accounts for the 80 ~ 90% of polytetrafluoroethylene film volume.
As preferably, the mass ratio between described polytetrafluoroethylene film and pore type polyurethane film is 1:6.5 ~ 7, thick Degree ratio is 1:0.3 ~ 0.6.
As preferably, the baking oven baking of described 80 ~ 150 degree of thermogrades specifically includes with the next stage:
The described first stage: under conditions of 80 DEG C, and carry out under the empty vapour atmosphere of low speeds flow；
Second stage: under conditions of 90 DEG C, and carry out under the empty vapour atmosphere of middling speed flowing；
Phase III: under conditions of 110 DEG C, and carry out under the empty vapour atmosphere of strong speed flowing；
Fourth stage: under conditions of 140 DEG C, and carry out under the empty vapour atmosphere of low speeds flow.
As preferably, described microspheres is akzonobel company microspheres, and it has resilient shell and is contained within The low-boiling point materials such as iso-butane, propane, pentane.
Owing to technique scheme is used, the present invention compared with prior art has following advantages and an effect:
1. the present invention is easy to the double-layer fabric thin film that human body water vapour is discharged, and can avoid due to pore type politef The materials such as the dust in the empty vapour of thin layer absorption, salt, oils and fats cosmetics and detergent in perspiration, it is achieved that for a long time Keep stable waterproof and perspire vapour performance；Next, combine and have the hydrophilic layer of polyurethane refusing oil and polytetrafluoroethylene film Layer, while improving external prevention rainwater performance, has and enhances the performance internally discharging human body antiperspirant vapour so that fabric There is more preferably comfort property and broader practice scope；Again, have a large amount of uniform due to this double-component thin-film material Hole, and there is the microvoid polyurethane resin bed of the hydrophilic type refusing oil, thus it is more beneficial for the discharge from human body water vapour, Greatly reduce the moisture of residual thin polyurethane film surface, thus improve the wearability of coating fabric and wear dry Refreshing, most importantly substantially increase the elasticity of PTFE film material, make clothing clothes at high sharp movement and extreme bar Also there is under part good mechanical property.
2. the present invention is easy to the double-layer fabric thin film that human body water vapour is discharged, specific for polytetrafluoroethylene film Combination, optimizes the formula of pore type polyurethane film, thus improves elasticity and adaptability, have high intensity simultaneously, do not inhale Water, anti-wear performance.

I. thermal impedance (GB/T 11048-2008 A method): 0.1097m K/W.
When using the above-mentioned double-layer fabric thin film being easy to the discharge of human body water vapour, can avoid due to pore type polytetrafluoro The materials such as the dust in the empty vapour of vinyl film layer absorption, salt, oils and fats cosmetics and detergent in perspiration, it is achieved that time long Between keep stable waterproof and perspire vapour performance；Next, combine and have the hydrophilic layer of polyurethane refusing oil and politef Thin layer, while improving external prevention rainwater performance, has and enhances the performance internally discharging human body antiperspirant vapour so that fabric Fabric has more preferably comfort property and broader practice scope；Again, have a large amount of equal due to this double-component thin-film material Even hole, and there is the microvoid polyurethane resin bed of the hydrophilic type refusing oil, thus be more beneficial for from human body water vapour Discharge, greatly reduce the moisture of residual thin polyurethane film surface, thus improve the wearability of coating fabric and wear Dry and comfortable, most importantly substantially increase the elasticity of PTFE film material, make clothing clothes in high sharp movement and pole Also there is under the conditions of end good mechanical property；Secondly, it, for the particular combination with polytetrafluoroethylene film, optimizes micropore The formula of type polyurethane thin film, thus improve elasticity and adaptability, have simultaneously high intensity, do not absorb water, anti-wear performance.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art Scholar will appreciate that present disclosure and implements according to this, can not limit the scope of the invention with this.All according to the present invention The equivalence that spirit is made changes or modifies, and all should contain within protection scope of the present invention.
