Manufacturing process of waterproof wear-resistant front shoe upper leather

The invention provides a manufacturing process of waterproof and wear-resistant front shoe upper leather, and relates to the technical field of shoe upper leather manufacturing. According to the manufacturing process of the waterproof wear-resistant front shoe upper leather, when waterproof leather coating work is carried out, an additive OS, wax emulsion, modified casein and the like can be added, the overall waterproof effect is improved, in the whole coating process, a cross-linking agent needs to be used every time slurry is applied, the strength of a coating film can be improved, the coating film has very high toughness, and the waterproof performance can be improved. A proper amount of salted leather is selected through a good raw material selection mode, strict grouping work is carried out, namely, raw material distinguishing is carried out manually, namely, the size, thickness, water content, oil content, fur coverage rate and weight of each piece of salted leather are measured, the salted leather wit
