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 vamp fabric convenient for water resistance and heat dissipation. The vamp fabric comprises a breathable layer, an interlayer and a waterproof layer; the breathable layer serves as an inner layer of the vamp fabric, and the breathable layer and the interlayer are separated by a cotton fiber net; the waterproof layer is compounded on the other surface of the interlayer; the surface of the waterproof layer is coated with a coating adhesive; and the breathable layer, the cotton fiber net, the interlayer and the waterproof layer are compounded by adopting a composite adhesive. The vamp fabric prepared by the invention has the characteristics of excellent water resistance, moisture removal, heat dissipation and air permeability, can timely discharge moisture and heat in a shoe cavity, has excellent air permeability and moisture penetrability, avoids breeding of bacteria in the shoe cavity, and greatly improves the comfort of shoes.

Description

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