Abstract

The utility model relates to an adopt EVA plastics to bond and weave double-sided belt of area material. The double-sided belt comprises a leather material on one side and a woven material on the other side, wherein the leather materials of the two materials are bonded through EVA plastics. The leather material and the woven material are combined into two surfaces of the double-sided belt by utilizing the performance that EVA plastics are melted at low temperature and can permeate into the inner part of the woven material. At the same time, the double-sided belt made of the material can be directly machined with edge cutting without sewing. The EVA plastic can be used for bonding the leather material and the woven material so as to manufacture the double-sided belt. Meanwhile, the double-sided belt made of EVA plastic still is firm without paper sewing, and one process is reduced because no sewing line is needed.

Description

Double-sided belt

Technical Field

The utility model relates to a double-sided belt especially relates to double-sided belt's two-sided connected mode.

Background

The double-sided belt is popular in the market because the double-sided belt can be used in a positive and negative way. In China, people are used to refer to artificial leather produced by taking PVC resin as a raw material as PVC artificial leather (artificial leather for short); the artificial leather produced by using the PU resin as a raw material is called PU artificial leather (PU leather for short); the artificial leather produced by using PU resin and non-woven fabric as raw materials is called PU synthetic leather (synthetic leather for short). A belt made of a woven material in the belt, namely a tank-line canvas belt (the canvas belt is in a belt type but not made of a material), when the belt is pushed, an automatic buckle on a belt buckle head rubs with the woven surface to generate clattering noise, so the belt is popular among young consumers. The woven material is generally woven by materials which do not resist high temperature, such as (PVC, PU) artificial leather, PU synthetic leather, polypropylene fiber, nylon and the like. The existing double-sided belt is usually adhered by glue, two sides of the belt are sewed by threads, and the belt is also sewed by the threads after being adhered by the glue. The woven belt has certain thickness, uneven surface and porous inside. When leather materials and the woven belt materials are used for manufacturing the double-sided belt, if glue is used for bonding, degumming can be caused; if hot melt adhesive is adopted for bonding, the high temperature resistance of the woven belt is poor due to the high temperature of the hot melt adhesive, and the woven material bonded by the molten hot melt adhesive shrinks and deforms due to the overhigh temperature; if a thread stitch is used. Therefore, the woven belt material cannot be used as a material for one side of a double-sided belt of a leather-side woven belt.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, a double-sided belt made of EVA plastic bonded woven belt materials is provided.

A double-sided belt comprises a leather material and a woven material on the other side, wherein the leather material and the woven material are bonded through EVA plastics. The leather material and the woven material are combined into two surfaces of the double-sided belt by utilizing the performance that EVA plastics are melted at low temperature and can permeate into the inner part of the woven material. At the same time, the double-sided belt made of the material can be directly machined with edge cutting without sewing.

Preferably, the woven material is a tank pattern canvas belt surface. The tank grain canvas belt is made of woven materials.

Preferably, the weaving material is made of any one of nylon, PVC artificial leather, PU artificial leather or PU synthetic leather.

The EVA plastic can be used for bonding the leather material and the woven material so as to manufacture the double-sided belt. Meanwhile, the double-sided belt made of EVA plastic still is firm without paper sewing, and one process is reduced because no sewing line is needed.

Detailed Description

The present invention will be described in further detail with reference to examples. EVA plastics are widely applied to the field of shoe making to produce foamed soles, but no example of application in the field of leather belt making exists at present.

A double-sided belt is provided, one side of which is made of a leather material and the other side of which is made of a woven material. When in processing, a leather material 1 made of leather material is entirely rolled and placed on the upper part, a knitted material 2 with a certain width is entirely rolled and placed on the lower part, melted EAV plastic is injected on the upper surface of the knitted material 2 on the lower part through an injection molding machine 3, and the leather material 1 and the knitted material 2 are pressed together through an upper pressing roller and a lower pressing roller 8 through a pressing roller (pressing working procedure); then, the sheet passes through a plurality of press roll groups 4 (cooling and setting step); the cutter device 5 carries out edge cutting (edge cutting process, which saves the original sewing process) on the double-sided belt semi-finished product which is obtained through the cooling and shaping process; and then the finished product is finally obtained after the detection of the laser machine 6.

Due to the uneven and internal porous structure (pores 9) of the woven material 2, the molten EVA plastic 7 (which has a low melting point and does not affect the woven material 2 when used for injection molding of the woven material 2) will penetrate into the porous structure (pores 9) inside the woven material 2. Meanwhile, after being melted, the EVA plastic 7 also fills and levels the uneven concave surface on the surface of the woven material 2 and is firmly jointed with the other surface of the leather material 1 to form a three-layer structure which is penetrated into the woven material 2. If the traditional glue is used, the adhesive force is not enough and is easy to fall off because the middle layer is too thin and can only be applied to the uneven convex surface of the woven material 2 and cannot penetrate into the porous structure in the woven material 2. Meanwhile, the three-layer structure penetrating into the woven material 2 is formed by the EVA plastic 7, and the two sides can be directly trimmed without extra sewing.

In short, the above description is only a preferred embodiment of the present invention, and all the equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the present invention.

Claims
