Problems solved by technology

However, PTFE waterproof and breathable membrane has very strong chemical inertness, and there is no good material to laminate it with other fabrics, and its water resistance is poor.
[0005] The common multi-material and multi-layer material composite structure of waterproof and breathable upper fabrics on the market generally adopts the coating composite method, but with this coating method, a layer of airtight film will be formed on the surface during coating to block the gap between the yarns. gaps, which greatly reduces the air permeability and heat dissipation of the composite fabric, which affects the comfort of shoes

Abstract

The invention discloses a shoe upper fabric which is convenient for waterproof and heat dissipation, which comprises a breathable layer, an interlayer and a waterproof layer; the breathable layer is used as the inner layer of the upper fabric, and the breathable layer and the interlayer are separated by a cotton fiber net; The other surface of the interlayer is composited with a waterproof layer; the surface of the waterproof layer is coated with coating glue; the air-permeable layer, the cotton fiber net, the interlayer and the waterproof layer are composited with a composite adhesive. The shoe upper fabric prepared by the present invention has the characteristics of excellent waterproof, moisture-dispelling, heat-dissipating and breathable, can discharge moisture and heat in the shoe cavity in time, has excellent air permeability and moisture permeability, avoids the breeding of bacteria in the shoe cavity, and greatly Improved shoe comfort.

Description

technical field [0001] The invention relates to the technical field of shoe upper fabrics, in particular to a shoe upper fabric that is convenient for waterproofing and heat dissipation. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, people's requirements for shoes are also getting higher and higher. Shoes not only have to meet the most basic requirements for protection and warmth, but their waterproof and heat dissipation properties are also increasingly valued by industry professionals and consumers. The research on the waterproof and functionalization of sole materials has become mature, while the research on functionalized upper materials has yet to be further developed. [0003] The traditional waterproof and heat-dissipating shoe material uses a slow and indirect diffusion process to discharge the heat and sweat vapor from the shoe to the outside of the shoe, but after a period of time, wh...
