Problems solved by technology

The disadvantage of one-sided gluing is that the bonding strength is low and it is easy to be torn
For example, when the composite skin obtained by laminating collagen fiber regenerated leather and knitted fabric (with a layer of polyurethane on the surface of the knitted fabric) is processed into a product, the edges and corners of the composite leather cannot be exposed, otherwise the product is easy to get out of the edge. The glue starts to open gradually, which affects the service life of the product
At the same time, the single-side gluing process also limits the application range of composite skins, because the composite skins obtained by using the single-side gluing process can only be applied to products that require edge wrapping.
Although the bonding strength of one-sided glue can be increased by increasing the amount of glue applied, this method wastes glue and increases production costs at the same time

Embodiment 1

[0029] The invention relates to a double-sided gluing composite process, which comprises the following steps in sequence:

[0030] (1) Cloth feeding: Collagen fiber regenerated leather and knitted fabric are drawn from the cloth feeding roller by the tension of the program-controlled cloth removing roller respectively;

[0031] (2) Gluing: Collagen fiber regenerated leather and knitted fabric are glued by passing between the rubberizing roller and the cloth guide roller respectively; by gluing, the first glue is formed on the side of the first fabric layer facing the second fabric layer surface, while forming a second adhesive surface on the side of the second fabric layer facing the first fabric layer. The first fabric layer is collagen fiber regenerated leather, and the second fabric layer is knitted cloth. Here, the rubber material is supplied to the hopper by the rubber compounding system, and then supplied from the hopper to the outer surface of the rubber-coating patter...

Embodiment 2

[0036] The invention relates to a double-sided gluing composite process, which comprises the following steps in sequence:

[0037] (1) Cloth feeding: Collagen fiber regenerated leather and non-woven fabric are drawn from the cloth feeding roller by the tension of the program-controlled cloth removing roller respectively;

[0038] (2) Gluing: Collagen fiber regenerated leather and non-woven fabric are respectively passed between the rubberizing roller and the cloth guide roller for gluing; by gluing, the first fabric layer is formed on the side of the first fabric layer towards the second fabric layer. The glue surface is formed at the same time on the side of the second fabric layer facing the first fabric layer to form a second glue surface. The first fabric layer is collagen fiber regenerated leather, and the second fabric layer is non-woven fabric. Here, the rubber material is supplied to the hopper by the rubber compounding system, and then supplied from the hopper to the...

Embodiment 3

[0043] The invention relates to a double-sided gluing composite process, which comprises the following steps in sequence:

[0044] (1) Cloth feeding: Collagen fiber regenerated leather and twill cloth are drawn from the cloth feeding roller by the tension pull of the program-controlled cloth removing roller respectively;

[0045] (2) Gluing: The collagen fiber regenerated leather and the twill cloth are glued by passing between the rubberizing roller and the cloth guide roller respectively; by gluing, the first rubber surface is formed on the side of the first fabric layer facing the second fabric layer , and at the same time form a second adhesive surface on the side of the second fabric layer facing the first fabric layer. The first fabric layer is collagen fiber regenerated leather, and the second fabric layer is twill cloth. Here, the rubber is supplied into the cylinder of the rubber coating roller by the rubber compounding system, and penetrates from the glue coating ho...

Abstract

The invention relates to a double-side gluing composition process sequentially comprising a cloth feeding step, a gluing step, a composition step, and a rolling step. A first fabric layer and a second fabric layer respectively pass between a gluing roller and a cloth guiding roller, such that gluing is carried out; a first glue surface is formed on the side of the first fabric layer facing the second fabric layer, and a second glue surface is formed on the side of the second fabric layer facing the first fabric layer; the first and second glue surfaces are both composed of glue dots distributed in a diamond or round scattered-dot mode; at least one layer of the first fabric layer and the second fabric layer is collagen fiber recycled leather. Compared with prior art, with the double-side gluing composition process provided by the invention, double-side scattered-dot gluing is adopted, such that bonding strength between the fabric layers is improved. Even if corners and edges of composed fabric are exposed, glue failure from the corners and edges is prevented. Also, glue material dose is saved, and production cost is reduced. The process is applied in composition of collagen fiber recycled leather and other fabric layer, such that composite leather application range can be widened.

Description

technical field [0001] The invention relates to a composite method of non-woven materials, in particular to a double-sided gluing composite process. Background technique [0002] The composite method of multi-layer fabric mainly includes two ways of sewing and gluing. Sutures are more suitable for lamination between knitted fabrics and / or woven fabrics, and glue is more suitable for lamination between collagen fiber regenerated skins or between collagen fibril regenerated skins and other fabrics, because the suture holes created by sutures will regenerate collagen fibers The belt brings stress concentration, which affects the strength and service life of collagen fibers. Another advantage of gluing is that the production speed is fast, the strength is high, and the appearance of the fabric after lamination is not affected. [0003] In the commonly used adhesive compounding process, glue is mostly applied on one side of a layer of fabric, and then the glued side of the laye...
