Abstract
The utility model discloses waterproof breathable superfine fiber synthetic leather. The waterproof breathable superfine fiber synthetic leather comprises a substrate layer and a surface layer, wherein the substrate layer consists of bundle superfine fibers and is filled with a foam structure; the foam structure is in a polyurethane foam structure, wherein foam holes in the structure are communicated with each other, so that the bundle superfine fibers and the foam structure have full freedom degree; therefore, the complete permeability of the substrate layer is ensured; after the substrate layer is subjected to hydrophobic treatment, the substrate layer cannot be expanded by liquid water content within a certain time, so that liquid is difficult to permeate through the substrate layer; and the surface layer is a structure provided with fine foam holes and provided with a polyurethane layer with certain hydrophobic property, so that gas water can pass through while liquid water cannot pass through because of surface tension. In the waterproof breathable superfine fiber synthetic leather, the waterproof and breathable performance is superior to common synthetic leather; moreover, the synthetic leather has a simple structure and is suitable for manufacturing various types of synthetic leather such as shoe leather and the like.
Description
Technical field
The utility model relates to the superfine fiber chemical leather of a kind of synthetic leather, particularly a kind of waterproof and breathable.
Background technology
Synthetic leather is a kind of The Nomenclature Composition and Structure of Complexes of simulating natural leather, and can be used as the plastic products of its substitute material, and it is widely used in making footwear, boots, case and bag and goods such as ball.At present, the synthetic leather that uses on the market is lamina reticularis with the nonwoven fabric through dipping usually, and the microvoid polyurethane layer makes as grain layer; And has certain gas permeability; But the hydrophobicity of this synthetic leather is relatively poor, causes its waterproof effect not good, also remote-effects the permeability of synthetic leather.
Summary of the invention
In order to address the above problem, the waterproof and breathable superfine fiber chemical leather that the utility model provides comprises base layer and superficial layer, and described base layer is made up of bundle superfine fibre, and is filled with foaming structure, and said superficial layer is a layer of polyurethane.
Said foaming structure is the polyurethane foam structure, and each abscess in its structure links up each other.
Said layer of polyurethane has fine foam structure.
The beneficial effect of the utility model is: because each abscess of the polyurethane foam layer of base layer inside links up each other; Make bundle superfine fibre and foaming layer that the sufficient free degree arranged, thereby guaranteed the complete gas permeability of base layer, base layer is through after the hydrophobic treatments; Make liquid moisture that the base layer profit is opened; Thereby it is bigger to make liquid pass through the difficulty of base layer, because superficial layer is a kind ofly to have fine bubble structure and certain hydrophobic layer of polyurethane is arranged, gas water can be passed through; And liquid water can't pass through because of the tension force on surface; The waterproof and breathable performance of the utility model is superior to general synthetic leather, and simple in structure, is suitable for all kinds of synthetic leather making such as footwear leather.
Description of drawings
Fig. 1 is the structure chart of the utility model.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model waterproof and breathable superfine fiber chemical leather comprises base layer 1 and superficial layer 2; Described base layer 1 is made up of bundle superfine fibre, and is filled with foaming structure 11, and said foaming structure 11 is the polyurethane foam structure; Each abscess in its structure links up each other; Make bundle superfine fibre and foaming structure 11 that the sufficient free degree arranged, thereby guaranteed the complete gas permeability of base layer 1, base layer 1 is through after the hydrophobic treatments; Make liquid moisture that base layer 1 profit is opened, thereby it is bigger to make liquid pass through the difficulty of base layer 1; Said superficial layer 2 gas water can be passed through, and liquid water can't pass through for having fine foam structure and certain hydrophobic layer of polyurethane being arranged because of the tension force on surface.
Above-described, be merely a preferred embodiment of the utility model, can not limit the scope that this practicality is implemented, every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
