KR-20260062336-A - Eco-friendly adhesive coating fabric for VOCs-Free shoe material

Abstract

The present invention relates to an eco-friendly adhesive-coated fabric for VOCs-free shoe materials and a laminated fabric using the same, which can reduce the overall thickness and improve the functionality and breathability of the base fabric or laminated fabric by laminating a base fabric and a laminated fabric using an adhesive fabric manufactured by weaving adhesive yarns coated with hot melt resin. An eco-friendly adhesive-coated fabric for VOCs-free shoe materials according to one embodiment of the present invention is an adhesive fabric that laminates between a plurality of fabrics to laminate the fabrics, wherein an adhesive yarn coated with hot melt resin on the outer surface of a single fiber is woven to form a through hole, and the hot melt resin is structured to be coated on the outer surface of the yarn with a thickness of 30 to 500 μm.

Claims (1)

1. In an adhesive yarn for manufacturing an adhesive fabric that is laminated between multiple fabrics to form a laminated fabric, It is made by weaving adhesive yarns, which are coated with hot melt resin on the outer surface of a single fiber and then aged at a predetermined temperature for a certain period of time, to form through holes. The above hot melt resin is an eco-friendly adhesive coating fabric for VOCs-Free shoe materials coated on the outer surface of the yarn to a thickness of 30 to 500㎛.

Description

Eco-friendly adhesive coating fabric for VOCs-Free shoe material The present invention relates to an adhesive mesh fabric, and more specifically, to an adhesive fabric made by weaving yarn that has been coated with a hot melt resin and then aged at a predetermined temperature for a certain period of time, and to an eco-friendly adhesive coating fabric for VOCs-free shoe materials made by laminating the adhesive fabric between two fabrics and bonding them by applying heat and pressure. Recently, a method of manufacturing products by laminating fabrics of different materials or fabrics of the same material with different colors is being widely used to improve the fashionability or functionality of products such as shoes, bags, wallets, or various pouches. The lamination of various fabrics as described above is typically achieved by laminating or applying a hot melt film or hot melt adhesive between a base fabric and a laminated fabric. For example, a method is proposed in which a hot melt film made of polyurethane material is placed between a base fabric and a laminated fabric, and then the two are compressed together to perform lamination. However, the conventional lamination method described above has the following problems. First, as a hot melt film or hot melt adhesive is formed between the base fabric and the laminated fabric, there is a problem in that the perforations of the fabric are closed by the hot melt film or hot melt adhesive, so breathability is not achieved. Second, when a stretchable fabric (e.g., spandex) is applied as a base fabric or laminated fabric for products requiring elasticity, there was a problem in that the elasticity was significantly reduced by the hot melt film or hot melt adhesive. Third, when mesh fabric was applied as a laminated fabric, the hot-melt adhesive leached out to the outer surface through the pores of the mesh fabric, which not only degraded the fashionability of the product and completely failed to express its functionality but also resulted in the product being considered defective and discarded. Fourth, in the case of hot melt films or hot melt adhesives, there was a problem in that there were many limitations in expressing various color effects on the laminated fabric because they could not realize a variety of colors desired by the user. Considering these problems, a method of laminating fabrics by sewing only the edges without bonding the bonding surfaces of the base fabric and the laminated fabric has been disclosed. However, since the base fabric and the laminated fabric are spaced apart at a certain distance, the fashionability, such as the tactile feel and appearance, is very poor due to the irregular fluidity of the laminated fabric, and the fabric fails to properly perform its function, such as allowing various foreign substances to be inserted. In particular, there was a problem in that production efficiency was significantly reduced because a sewing process had to be included as a necessity. To solve these problems, there is the "method for laminating fabrics using an adhesive fabric and a fabric laminated by the same lamination method" disclosed in Registered Patent No. 10-1604123. Unlike the conventional method of laminating by laminating or applying a hot-melt film or hot-melt adhesive between a base fabric and a laminated fabric, the above registered patent involves coating a yarn with a hot-melt resin, weaving an adhesive fabric using this, laminating the adhesive fabric between the base fabric and the laminated fabric, and then laminating them together. This method does not interfere with the functionality (e.g., elasticity) of the base fabric or the laminated fabric, and also allows for improved breathability of the fabric through the perforations of the adhesive fabric. However, these conventional adhesive fabrics have drawbacks: because they are made by twisting multiple strands of fiber or using composite yarns consisting of a core and a seed layer, the hot-melt resin is not uniformly coated on the outer surface of the yarn, resulting in reduced adhesive strength; or the adhesive fabric itself becomes thick, which consequently increases the overall thickness of the laminated fabric when the base fabric and the laminated fabric are bonded together, thereby limiting the improvement of functionality, and the outline of the adhesive fabric becomes visible on the outside of the other fabric.
