Description

High tenacity yarn composite structure

Technical field

The utility model relates to shoes to remove from office field technology, refer in particular to a kind of High tenacity yarn composite structure.

Background technique

Currently, common leather can divide into two major classes: natural leather and synthetic leather.

Natural leather is made of the skin for taking animal, such as sheepskin, ox-hide, and suture production article by leather makes for the mankind With such to be continued into the present by the way of leatherwork article, though existing natural leather has figure decoration, solid color is in beauty See the aesthetic quite dullness that seems.In addition the cost for obtaining natural leather is gradually increased, in the supreme viewpoint of modern trend trend On, substantially reduce modern purchase attraction.

Substitute of the synthetic leather as natural leather, is widely used in dress material, leather boots, suitcase etc..It is existing artificial synthesized Leather be generally combined by multilayer material, synthetic leather or artificial leather are by textile cloth base or non-woven fabrics base, respectively with poly- Urethane applies redoubling using made of special foaming processing, has surface feel to exactly like corium, however, this synthetic leather waterproof and breathable Property is poor, and mechanical strength is low, is not able to satisfy the needs used.Therefore, it is necessary to be improved to current leather.

Summary of the invention

In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of high-tenacity Yarn composite structure can effectively solve existing leather water-proof poor air permeability and the low problem of mechanical strength.

To achieve the above object, the utility model is using following technical solution:

A kind of High tenacity yarn composite structure includes base cloth layer, waterproof ventilated membrane, hot melt adhesive layer and the surface layer PU； The base cloth layer is High tenacity yarn screen cloth material；The surfaces externally and internally of the fully wrapped around firmly base cloth layer of the waterproof ventilated membrane；The hot melt adhesive layer It for lamination TPU, is covered on the surface of waterproof ventilated membrane, hot melt adhesive layer has multiple evenly arranged convex closures；The surface layer PU It is covered on the surface of each convex closure.

Preferably, the base cloth layer with a thickness of 0.2-0.4mm.

Preferably, the hot melt adhesive layer with a thickness of 0.1-0.2mm.

Preferably, the surface layer PU with a thickness of 0.05-0.1mm.

The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology Known to scheme:

By using High tenacity yarn screen cloth material, so that this product mechanical strength with higher, high dimensional stability, and Cooperation utilizes the surfaces externally and internally of the fully wrapped around firmly base cloth layer of waterproof ventilated membrane, so that this product is provided simultaneously with preferable waterproof and breathable Performance meets the needs used.

For the structure feature and effect for more clearly illustrating the utility model, come with reference to the accompanying drawing with specific embodiment pair The utility model is described in detail.

Detailed description of the invention

Fig. 1 is the sectional view of the preferred embodiment of the utility model.

Description of drawing identification:

10, base cloth layer 20, waterproof ventilated membrane

30, hot melt adhesive layer 31, convex closure

32, ventilative gap 40, the surface layer PU.

Specific embodiment

It please refers to shown in Fig. 1, it to include base cloth layer that show the specific structures of the preferred embodiment of the utility model 10, waterproof ventilated membrane 20, hot melt adhesive layer 30 and the surface layer PU 40.

The base cloth layer 10 be High tenacity yarn screen cloth material, mechanical strength with higher, high dimensional stability, also, The base cloth layer with a thickness of 0.2-0.4mm.

The surfaces externally and internally of the fully wrapped around firmly base cloth layer 10 of the waterproof ventilated membrane 20；In the present embodiment, the waterproof ventilated membrane 20 be plastic cement material, is penetrated into each mesh of base cloth layer 10, waterproof ventilated membrane 20 with a thickness of 0.1-0.2mm.

The hot melt adhesive layer 30 is lamination TPU, is covered on the surface of waterproof ventilated membrane 20, and hot melt adhesive layer 30 has multiple Evenly arranged convex closure 31 is formed with ventilative gap 32 between adjacent two convex closure 31, to realize better permeability, in this reality Apply in example, the hot melt adhesive layer 30 with a thickness of 0.1-0.2mm.

The surface layer PU 40 is covered on the surface of each convex closure 31, in the present embodiment, the surface layer PU with a thickness of 0.05- 0.1mm。

When production, firstly, the surfaces externally and internally in base cloth layer 10 forms waterproof ventilated membrane 20, then, in waterproof ventilated membrane 20 Surface forming hot melt adhesive layer 30, finally, the surface layer PU 40 is arranged on the surface of each convex closure 31.

The design focal point of the utility model is: by using High tenacity yarn screen cloth material, so that this product is with higher Mechanical strength, high dimensional stability, and cooperate the surfaces externally and internally using the fully wrapped around firmly base cloth layer of waterproof ventilated membrane, so that this production Product are provided simultaneously with preferable waterproof and breathable performance, meet the needs used.

Technical principle of the utility model has been described above with reference to specific embodiments.These descriptions are intended merely to explain this reality With novel principle, and it cannot be construed to the limitation to scope of protection of the utility model in any way.Based on the explanation herein, Those skilled in the art, which does not need to pay for creative labor, can associate with other specific implementation modes of this utility model, These modes are fallen within the protection scope of the utility model.
