Preparation method of composite fabric

Abstract

The invention belongs to the technical field of production and processing of fabric, and discloses a preparation method of composite fabric. The preparation method of the composite fabric comprises the following steps: (1) dust removal, wherein dust removal treatment is performed on an intermediate layer and a composite layer; (2) glue melting, wherein hot melt glue is melted into a liquid state;(3) coating, wherein the liquid hot melt glue is coated on both surfaces of the intermediate layer obtained after dust removal is performed; (4) combination, wherein each of both surfaces of the coated intermediate layer is covered with a composite layer so as to form a semi-finished product; (5) press fit, wherein pressurizing press fit is performed on two sides of the semi-finished product; and(6) still standing, wherein the semi-finished product obtained after press fit is finished is put into a curing chamber for still standing treatment. According to the preparation method of the composite fabric, the adopted hot melt glue is an environment-friendly material, has the advantages of low odor and low VOC emission, is beneficial to the physical health of operators and users, and can meetrequirements of environmental protection; and in addition, the viscosity of the hot melt glue is high, the phenomena of easy delamination and falling off can be avoided during use, so that the bonding firmness and durability are increased, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of fabric production and processing, in particular to a method for preparing a composite cloth. Background technique [0002] As a new type of fabric load-bearing material, composite fabric has the advantages of wear resistance and high and low temperature resistance, and is widely used in industry and people's daily life. [0003] Existing composite cloths are usually made by laminating the cloths by pressing equipment after the surface of the fabric is coated with a layer of adhesive. The adhesive of the traditional craft is directly coated with industrial glue, which is prone to organic residues and the release of toxic gases during the production process. The smell is strong, long-lasting and not easy to dissipate. It is not only harmful to the human body, but also not conducive to the needs of energy conservation and environmental protection. At the same time, the viscosity of the adhesive is low, whic...

The adhesive of the traditional craft is directly coated with industrial glue, which is prone to the residue of organic matter and the release of toxic gas during the production process. The smell is strong, long-lasting and not easy to dissipate. It is not only harmful to the human body, but also not conducive to the needs of energy conservation and environmental protection.

At the same time, the viscosity of the adhesive is low, which makes the bonding and fixing between the fabrics poor, and the problem of delamination and falling off is prone to occur during use
