A process of making high-grade oily wax leather from low-grade split leather with many veins

Abstract

The invention relates to the technical field of leather and in particular relates to a technology for producing multi-vein-mark low-grade split leather into high-grade wax leather. The technology comprises the following steps: putting vein-mark leather subjected to dyeing treatment into a baking oven and baking to obtain dried leather; putting the dried leather into a steel drum, and vibrating andmilling to obtain a milled leather blank; carrying out dull polishing on the milled leather blank for one time by utilizing 180#, 280# and 220# abrasive paper; putting the polished leather blank intothe steel drum; then vibrating and milling again for 1h, and putting into a rolling coating machine; coating wax in a rolling manner; ironing and flattening the rolling-coated leather blank by utilizing an ironing machine; putting the leather blank on a slurry spraying machine; continuously spraying for two times and putting the leather blank into the ironing machine and ironing and flattening again, so as to carry out secondary waxing on the leather blank; putting the leather blank subjected to secondary ironing and flattening into the steel drum and vibrating and milling again, so as to obtain the high-grade wax leather with a vintage feeling. The high-grade wax leather produced by the technology has the advantages of good stretching performance, wearing resistance, no easiness of de-coloring and relatively low cost.

Description

technical field [0001] The invention relates to the technical field of leather, in particular to a process for making high-grade oily wax leather from low-grade split leather with many veins.
