Problems solved by technology

There is a color difference in each sheet, which makes it difficult to cut the needle car
Although artificial leather can be purchased in large quantities and has a uniform color, it is not breathable, does not absorb moisture, and is easy to become brittle and deformed at low temperatures
Although chemical fiber textile materials are light and soft, they have poor air permeability
The waterproof performance of the above materials is also not good
Animal leather, artificial leather, and chemical fiber materials are prone to pollution during the production process, and the finished products are difficult to degrade, which is not good for the environment

Embodiment Construction

[0023] A shoe with DuPont paper as the upper. The DuPont paper composite material is the same as traditional materials such as artificial PU, basically without any restrictions. DuPont paper maintains strength and flexibility at temperatures as low as -73°C. DuPont paper begins to shrink at around 104°C and melts at 135°C. During heat-set offset printing on web, the oven temperature must not exceed 79°C. The thickness of DuPont paper can be determined according to the style of shoes and the thickness of the composite material, so there is no limit to the thickness of the paper in general. However, the biggest difference between DuPont paper and other materials is that the material itself has no elasticity, so it has certain limitations on some shoe styles, and it will be difficult to make styles such as big head row.

[0024] After the upper is completed, the shoe is completed by injection molding the outsole to the upper. The DuPont Tyvek upper series products, the outsole...

Abstract

A shoe taking Dupont paper as a vamp and a production method thereof are disclosed, the shoe comprises the vamp and a sole, the vamp is fixedly connected to the sole, and the vamp is made of Tyvek Dupont paper. The method has the advantages that under the optimal condition, water and carbon dioxide can be generated after Tyvek- is incinerated, and residues needing to be treated are basically not left; the Tyvek- can be buried, and the buried Tyvek- cannot permeate into underground water because the chemical property of the Tyvek- is inert and does not contain an adhesive. The vamp made of Dupont Tyvek also has the advantages of water resistance, air permeability, bending resistance, aging resistance and the like. Meanwhile, environmental protection is facilitated.

Description

technical field [0001] The invention relates to the field of shoes, in particular to a shoe with DuPont paper as the upper and a production method thereof. Background technique [0002] The current main materials of shoe uppers include animal leather, artificial leather, chemical fiber cloth and so on. Animal leather mainly includes cowhide, sheepskin, deerskin, etc., with few sources and difficult to purchase. There is chromatic aberration in each sheet, which makes it difficult to cut and stitch. Although artificial leather can be purchased in large quantities and has a uniform color, it is not breathable, does not absorb moisture, and is easy to become brittle and deformed at low temperatures. Although chemical fiber textile materials are light and soft, they have poor air permeability. The waterproof performance of the above materials is also not good. Animal leather, artificial leather, and chemical fiber materials are prone to pollution during the production proces...
