Abstract

The invention relates to the technical field of fabric preparation, and provides a composite fabric and a preparation method thereof in order to solve the problem that an existing composite fabric is poor in antibacterial performance and fracture resistance, the composite fabric comprises a first composite layer, an antibacterial layer and a second composite layer, and the antibacterial layer comprises an antibacterial coating; wherein each of the first composite layer and the second composite layer comprises a non-woven fabric and a modified coating, and one side of the non-woven fabric is uniformly coated with the modified coating; and the other side of the non-woven fabric is uniformly coated with an antibacterial coating. The two sides of the non-woven fabrics are coated with the modified coating and the antibacterial coating respectively, the antibacterial coating plays an antibacterial role and also serves as a bonding layer to bond the two non-woven fabrics to prepare the composite fabric, the preparation efficiency is improved, the antibacterial effect is uniform and good, and the composite fabric has excellent fracture resistance; besides, the butanone is added in the preparation process, so that the adhesion performance of the modified coating is improved.

Description

technical field [0001] The invention relates to the technical field of fabric preparation, in particular to a composite fabric and a preparation method thereof. Background technique [0002] Composite fabric is a new type of material made by bonding one or more layers of textile materials, non-woven materials and other functional materials. Different composite materials are doped in it to make the composite fabrics have different properties. The existing composite fabrics cannot meet the requirements of hygiene, safety and durability in use, and do not have antibacterial properties and anti-fracture properties. Therefore, a composite fabric and a preparation method thereof are urgently needed to solve the above-mentioned technical problems. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to propose a composite fabric and a preparation method thereof in order to solve the shortcomings existing in the prior art. [0004] In order to achieve the ab...
