And TPU is a kind of environment-friendly materials of maturation, the characteristics such as it has other plastics and the incomparable intensity of natural material is high, good toughness, wear-resisting, cold-resistant, oil resistant, water-fast, ageing-resistant and weatherability, it also has the function of many excellences such as very high water proofing property, poisture-penetrability, windproof, cold-proof, antibacterial, mildew-resistant, warming, uvioresistant and energy release simultaneously.At present, TPU has been widely used in the aspects such as clothing, footwear, health care, electronic apparatus, industry and sports equipment.TPU and other macromolecular material are processed jointly, can access the polymer of performance complement.
In view of this, the necessary a kind of two-sided clip cloth and preparation method thereof that provides, it is by being bonded in TPU thin layer on nexine and the top layer of natural leather layer, natural leather water proofing property, fire line, anti-corrosive properties, anti-friction function and the poor shortcoming of scratch resistant function have been overcome, practical value and the serviceability of natural leather have greatly been improved, reduce the inadaptability of natural leather goods to human body, improve wear-resisting, the waterproof of leather, anti-friction scratch resistant, anticorrosion, fire prevention and the function such as ventilative, and can keep natural leather surface-brightening colour-fast, do not fade.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and provide a kind of double-sided TPU fabric, it is by being bonded in TPU thin layer on nexine and the top layer of natural leather layer, natural leather water proofing property, fire line, anti-corrosive properties, anti-friction function and the poor shortcoming of scratch resistant function have been overcome, practical value and the serviceability of natural leather have greatly been improved, reduce the inadaptability of natural leather goods to human body, improve wear-resisting, the waterproof of leather, anti-friction scratch resistant, anticorrosion, fire prevention and the function such as ventilative, and can keep natural leather surface-brightening colour-fast, do not fade.
For achieving the above object, the utility model adopts following technical scheme:
A double-sided TPU fabric, it comprises natural leather layer and TPU thin layer, described TPU thin layer is adhered to top layer and the nexine of described natural leather layer by TPU hot melt adhesive layer.
As a kind of improvement of the utility model double-sided TPU fabric, described natural leather layer is pig leather layer, ox leather layer, sheep layer, horse leather layer, donkey leather layer and kangaroo leather layer, fish leather layer, reptile leather layer, amphibian animal leather layer or ostrich leather layer.
As a kind of improvement of the utility model double-sided TPU fabric, the thickness of described TPU thin layer is 0.01mm~5mm, and the thickness of described natural leather layer is 1mm~5mm, and the thickness of described TPU hot melt adhesive layer is 0.001-0.2mm.
As a kind of improvement of the utility model double-sided TPU fabric, the thickness of described TPU thin layer is 0.1mm~3mm, and the thickness of described natural leather layer is 1.5mm~3mm, and the thickness of described TPU hot melt adhesive layer is 0.005-0.15mm.
As a kind of improvement of the utility model double-sided TPU fabric, the thickness of described TPU thin layer is 1mm, and the thickness of described natural leather layer is 2mm, and the thickness of described TPU hot melt adhesive layer is 0.01mm.
As a kind of improvement of the utility model double-sided TPU fabric, on described TPU thin layer, be provided with embossing or printed layers.
With respect to prior art, the utility model is by being bonded in TPU thin layer on nexine and the top layer of natural leather layer, both protected the nexine of natural leather layer, protected again the top layer of natural leather layer, not only keep the performances such as wear-resisting, the environment-protective no-smell of natural leather and nondiscolouring, and kept its surface-brightening, smooth, softness and the high advantage of elasticity; Natural leather water proofing property, fire line, anti-corrosive properties, anti-friction function and the poor shortcoming of scratch resistant function have also been overcome simultaneously, practical value and the serviceability of natural leather have greatly been improved, prevent the generation of peculiar smell, the uncomfortable disease of skin that clothes prepared by this folder cloth of minimizing human body dress use, shoes and hats etc. produce, improve people's wearing comfort, improve wear-resisting, the waterproof of leather, anti-friction scratch resistant, anticorrosion, fire prevention and the function such as ventilative simultaneously, and can keep natural leather surface-brightening colour-fast, do not fade.
