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. Background technique [0002] Oil wax leather is a special leather effect formed by polishing, oiling and waxing the top layer of cowhide. It is a fashionable leather craft with an antique artistic effect, and it is also the leather material of choice for major world brands. Due to its technical characteristics, the surface of oil wax leather is easy to leave scratches, which will disappear after repeated application along the grain direction with shoe shine cloth or shoe wax. In addition, oil wax leather has strong water and oil absorption, and the color of the leather surface will become darker when it sticks to water and oil. In fact, it is these characteristics of oil wax leather that make it feel nostalgic and vicissitudes , is the main reason for its popularity. However, the pric...
