Abstract
The utility model provides stitching-free hot melt adhesive leather, relating to the technical field of artificial leather. The stitching-free hot melt adhesive leather comprises a dry type PU (Poly Urethane) layer, a TPU (Thermoplastic Urethanes) membrane layer and a TPU hot melt adhesive layer, wherein one side of the TPU membrane layer is clung to the dry type PU layer, the other side of the PU layer is clung to the TPU hot melt adhesive layer, the dry type PU layer and the TPU membrane layer have the characteristics of water proofness, ventilation, bacterium and wear resistance, high elasticity and ageing resistance; and the TPU hot melt adhesive can be clung to various fabrics and plastics without using glue water, thus the stitching-free hot melt adhesive leather is environment friendly. Therefore the stitching-free hot melt adhesive leather made of three materials has the advantages of high adhering strength, smooth surface, soft hand feel, high biofidelity, and wash cleaning and dry cleaning resistance.
Description
Technical field
The utility model relates to the artificial leather technical field, and is particularly a kind of without sewing PUR leather.
Background technology
PU is the abbreviation of English polyurethane, chemical Chinese " polyurethane ".The PU artificial leather is exactly the epidermis of polyurethane composition, is widely used in now makeing the decoration of case and bag, clothes, footwear, vehicle and furniture, and it obtains affirming of market day by day, its range of application is wide, quantity is big, more than the kind, is that traditional natural leather can't satisfy.
Yet, because the PU artificial leather often adds some poisonous auxiliary material such as DMF (containing dimethyl formamide) in manufacture process, there is certain defective in it in application, and contained DMF is poisonous, not only not environmental protection, and excessive use can cause that the consumer is allergic, fash or burn.In addition, the performances such as the elasticity of PU artificial leather, toughness, wearability, cold resistance still can not be satisfied with the product of making some high requests, and using glue with various clothes, plastic cement when fitting, produce so easily be full of cracks, break.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model be to provide a kind of environmental protection, nontoxic, adhesion is strong, water-fastness, anti-dry-cleaning, and with various clothes, plastic cement need not use when fitting glue without sewing PUR leather.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of without sewing PUR leather, comprise dry type PU layer, TPU rete and TPU hot melt adhesive layer; One side of described TPU rete and described dry type PU laminating close, and opposite side and described TPU hot melt adhesive layer are fitted.
Preferably, a side of the relatively described TPU rete of described dry type PU layer is provided with off-style paper layer.
Preferably, a side of the relatively described TPU rete of described dry type PU layer is provided with the PET release film layer.
By technique scheme, the utility model provide without sewing PUR leather, adopt the materials processing of dry type PU, TPU film and three kinds of same natures of TPU PUR to form.Wherein, dry type PU and TPU film all have waterproof, ventilative, antibiotic, wear-resisting, characteristic that elasticity is high, ageing-resistant, and the TPU PUR can be fitted with various clothes, plastic cement, need not glue when bonding, environment-protecting asepsis.Therefore, three kinds of materials make without sewing PUR leather not only bonding strength height, surface smoothing, soft, fidelity is high, and performance water-fastness, anti-dry-cleaning is high.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment.
Fig. 1 is the utility model embodiment one disclosed a kind of schematic diagram without sewing PUR leather;
Fig. 2 is the utility model embodiment two disclosed a kind of schematic diagrames without sewing PUR leather.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
It is a kind of without sewing PUR leather (referring to Fig. 1) that the utility model provides, and comprises dry type PU layer 1, TPU rete 2 and TPU hot melt adhesive layer 3; One side of TPU rete 2 and dry type PU layer 1 are fitted, and opposite side and TPU hot melt adhesive layer 3 are fitted.Wherein, dry type PU and TPU film all have waterproof, ventilative, antibiotic, wear-resisting, characteristic that elasticity is high, ageing-resistant, and the TPU PUR can be fitted with various clothes, plastic cement, need not glue when bonding, environment-protecting asepsis.Therefore, three kinds of materials make without sewing PUR leather not only bonding strength height, surface smoothing, soft, fidelity is high, and performance water-fastness, dry-cleaning is high.
Embodiment one:
One side of dry type PU layer 1 relative TPU rete 2 is provided with off-style paper layer 4, is used for preventing the 1 contaminated and scuffing of dry type PU layer.
Embodiment two:
One side of dry type PU layer 1 relative TPU rete 2 is provided with PET release film layer 4', is used for preventing the 1 contaminated and scuffing of dry type PU layer.
The utility model provide without sewing PUR leather, adopt the materials processing of dry type PU, TPU film and three kinds of same natures of TPU PUR to form, environment-protecting asepsis, can replace PU artificial leather and other leather to use, itself and various cloth, need not to use glue when plastic cement is bonding, not only bonding strength height, surface smoothing, soft, fidelity is high, and performance water-fastness, anti-dry-cleaning is high.
Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (3)
