Problems solved by technology

[0002] Ordinary sports and leisure PU synthetic leather is made of general non-woven fabric base and polyurethane resin to achieve the same breaking and tearing strength. Not only is it thick and heavy, but also has large wrinkles and poor shape of the finished shoe. It is bulky to wear and extremely inconvenient to move, which affects the lightness and comfort of wearing, and cannot follow the development trend of beauty, fashion and lightweight in the field of shoe leather in the market

Embodiment 1

[0032] The present embodiment carries out according to the following steps:

[0033] 1. Select the ultra-thin composite cloth base with a thickness of 0.4mm and a mass ratio of fiber components (nylon: polyester = 50:50) as the base material;

[0034] The ultra-thin composite fabric base is processed by woven fabric and non-woven fabric (both fiber components are nylon and polyester with a mass ratio of 50:50) by laying and needling bonding.

[0035] 2. Using wet-process synthetic leather production equipment, the ultra-thin composite cloth base is impregnated and coated with wet-process to make wet-process semi-finished products;

[0036] Polyurethane impregnation slurry is obtained by the following raw materials in parts by mass:

[0037]

[0038] The preparation method of polyurethane impregnation slurry is: add 250 parts of DMF and 0.8 parts of water repellent F-3D to the wet batching kettle in sequence, and stir for 10 minutes at normal temperature and pressure, and t...

Abstract

The invention discloses a method for producing an ultra-thin lightweight leather for sports and leisure shoes, which is characterized in that ultra-thin composite fabric base is taken as a base material, a wet synthetic leather semi-finished product is produced by a wet method; then the surface of the semi-finished product is polished and processed by a dry method, and finally the ultra-thin lightweight leather for sports and leisure shoes can be produced. The ultra-thin lightweight leather for sports and leisure shoes has the characteristics of ultra-thin thickness, light weight and high physical property, and has the advantages of little buckling, good hand feeling and good sizing performance, can completely accord with development trend of beauty, fashion and light weight of the current leather for leisure shoes.

Description

technical field [0001] The invention relates to a method for manufacturing ultra-thin and light-weight sports and leisure shoe leather. Background technique [0002] Ordinary sports and leisure PU synthetic leather is made of general non-woven fabric base and polyurethane resin to achieve the same breaking and tearing strength. Not only is it thick and heavy, but also has large wrinkles and poor shape of the finished shoe. It is bulky to wear and extremely inconvenient to move, which affects the lightness and comfort of wearing, and cannot conform to the trend of beauty, fashion and lightweight development in the field of shoe leather in the market. Contents of the invention [0003] The purpose of the present invention is to provide a sports and leisure shoe leather with extremely thin thickness, ultra-light weight, high physical properties, small wrinkles, good flexibility and good shape, so as to ensure that the finished shoe products are light, comfortable and durable....
