Problems solved by technology

[0002] The traditional mesh cloth is wear-resistant and poor in durability. After a period of use, the finished product is prone to surface wear, threading, mesh deformation and other problems, and it cannot be repaired.
At the same time, the traditional mesh fabric has poor waterproof and windproof performance. When the finished mesh fabric is outdoors, it is easy to get water in rainy days and cannot be used. When the temperature is low in winter, it cannot keep out the cold, and the use conditions are harsh.
Nowadays, when consumers purchase sports shoes, casual shoes, running shoes, luggage, clothing and other mesh products that can be used outdoors, they pay more attention to the combination of functionality and comfort. Traditional mesh obviously cannot meet such needs.

Abstract

The invention discloses a TPU high and low temperature membrane composite mesh cloth and a preparation method thereof. The TPU high and low temperature membrane is sequentially compounded with the mesh cloth through initial compounding and vacuum suction to obtain a TPU high and low temperature membrane composite mesh cloth. The invented preparation method transforms traditional mesh products. On the basis of inheriting the softness, light weight and comfort of traditional mesh fabrics, it has excellent water repellency and wind resistance, strong self-repair ability, rich surface effects, and strong three-dimensional effect. The mesh cloth does not need to be dyed, which can reduce environmental pollution. At the same time, it has excellent wear-resistant and scratch-resistant performance, good shape and durability after finished shoes, and is not easy to be deformed and damaged. It can meet the market's requirements for functionality and diversity of traditional mesh products and traditional polyurethane synthetic leather products.
