Toe box and heel cap material for shoes and method of manufacturing toe box and heel cap material for shoes

Abstract

The invention provides a toe box and heel cap material for shoes and a method of manufacturing the toe box and heel cap material for shoes. The toe box and heel cap material for shoes comprises a sandwich layer and a surface layer wrapping the same, wherein the sandwich layer is made of 100 parts of polyurethane, 60 parts of low-temperature polyester, 5 parts of triethylene diamine, 3 parts of stannous octoate, 5 parts of 1,4-Butanediol, and 6 parts of trimethylolpropane, and the surface layer is made of 100 parts of hot melt glue level polyurethane and 30 parts of thermoplastic elastomer. The hardness and strength of the toe box and heel cap material for shoes are improved further, the toe box and heel cap material is easy to trim and excellent in bending resistance, the toe box and heel cap material is active at low temperature and free of glue overflow, opening time is shortened so that the material can be shaped quickly, and the toe box and heel cap material has high bonding power. Leftover obtained by trimming the material can be recycled and reused. By the method of manufacturing the toe box and heel cap material for shoes, manufacturing procedures are simplified for enterprises, operation is facilitated for shoe makers, and production efficiency and labor intensity are reduced for the shoe makers.

Description

technical field [0001] The invention relates to a material placed in a shoe to increase the strength and hardness of the shoe, more specifically, a front lining and back cover material for a shoe and a manufacturing method thereof. Background technique [0002] The front lining and the back cover of the shoe are reinforcing devices for the inside of the toe cap and the heel. They are placed between the inner surface and the inner lining of the shoe to maintain the shape of the shoe and increase the strength and hardness of the shoe. At present, the front lining and back cover materials commonly used in the shoemaking industry are solvent-based chemical sheets or heat-setting films, which take too long to set in the process of specific use, and due to material limitations, shoemakers have to During the manufacturing process, too many processes are required, which not only increases the labor intensity of the shoemakers, but also is not conducive to improving the production ef...
