Description
Technical field
The utility model relates to technical field of textile fabric, particularly relates to a kind of polyurethane composite membrane of waterproof and ventilating.
Background technology
Polyurethane fabric (PU 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 durable, and because of Prof. Du Yucang technology maturation price comparatively cheap, be widely used at garment industry.The PU fabric of prior art is the fabric of single PU structure sheaf, and because PU fabric resistance to water is poor, thus the clothes of PU fabric generally can not be washed, and can only adopt dry-cleaning, and then improve cleaning cost.
Another PU fabric gas permeability is poor, reduces comfort level when PU fabric clothes is worn, such as, perspire when wearing and cannot discharge.In addition, the poor and surperficial phenomenon occurring be full of cracks, come off of the wearability of PU fabric.
But for the deficiencies in the prior art, developer is necessary that development is a and has good resistance to water, gas permeability and wearability, the polyurethane composite membrane of the waterproof and ventilating of long service life.
Utility model content
For solving prior art Problems existing, the utility model object provides one and has good resistance to water, gas permeability and wearability, the polyurethane composite membrane of the waterproof and ventilating of long service life.
For solving above technical problem, the utility model comes to be realize by the following technical solutions: a kind of polyurethane composite membrane of waterproof and ventilating, comprises
One to form with coating process coating and to be mainly used in improving the layer of polyurethane of this composite membrane water resistance;
One is coated in the adhesive layer of the upper and lower both sides of described layer of polyurethane with coating process;
One is coated in the upper surface of the adhesive layer of described layer of polyurethane upper surface coating with coating process and is mainly used in improving the protective layer of this composite membrane mar proof;
One is coated in the lower surface of the adhesive layer of described layer of polyurethane lower surface coating with coating process and is mainly used in improving the base cloth layer of this composite membrane permeability;
One is stamped in the lines layer of described protective layer upper surface with imprint process.
In a preferred embodiment of the present utility model, described layer of polyurethane is aqueous polyurethane layer.
In a preferred embodiment of the present utility model, described adhesive layer is PU paste layer.
In a preferred embodiment of the present utility model, described protective layer is PTFE Filled with Carbon Fiber protective layer.
In a preferred embodiment of the present utility model, described base cloth layer is micro-porous breathable type base cloth layer.
The beneficial effects of the utility model are; Compared with prior art, the utility model comprises and to form with coating process coating and to be mainly used in improving the layer of polyurethane of this composite membrane water resistance, and layer of polyurethane is aqueous polyurethane layer, thus improves the water resistance of this composite membrane; In layer of polyurethane upper and lower both sides, coating process is coated with adhesive layer, adhesive layer is PU paste layer, thus be bonded together being arranged on below layer of polyurethane with layer of polyurethane firmly with the base cloth layer of top and protective layer, thus improve the stability of this composite membrane; But protective layer is PTFE Filled with Carbon Fiber protective layer, thus improve the anti-wear performance of this composite membrane; And base cloth layer is micro-porous breathable type base cloth layer, thus improve the permeability of this composite membrane, further increase comfort level when clothes is worn; In addition, surface imprint process has also impressed lines layer on the protection layer, thus improves the visual effect of this composite membrane.
