Abstract

The invention discloses a dual-purpose modification process for native breed sheepskin leather. The process sequentially comprises the following steps of processing native breed sheepskin semi-finished products: (1) classifying skin; (2) returning water; (3) soaking; (4) softening; (5) pickling; (6) performing chromium aluminum tanning; (7) performing tanning post-processing; (8) performing chrome retanning; (9) performing chrome retanning before dyeing; and (10) dyeing. According to the dual purpose modification process, commercially available native breed semi-finished skin (namely white skin) is processed, and the native breed semi-finished skin is tanned by increasing aldehyde aluminum tanning particularly, so that the extensibility of the native breed sheepskin can be effectively improved, the problem of dyeing defects is solved, and the uniformity in the post dyeing is ensured. The dual purpose modification process is matched with other steps and appropriate additives, and each additive is added according to reasonable additive amount, so that the final products have good handfeeling, high tearing resistance and high fullness, and the quality of the native breed sheepskin leather is greatly improved.

Description

[0001] technical field [0002] The invention relates to a production process of a fur product, in particular to a dual-purpose refitting process of semi-finished fur and leather of native sheep. Background technique [0003] The local sheepskin can be used to cut and sew all kinds of clothing after being processed through multiple processes. At present, the native sheepskin sold in the market has the disadvantage of poor tear strength, which leads to insufficient firmness of the finished product, and its poor fullness affects the quality of the clothes made from the native sheepskin. In order to increase the quality of clothing, it is necessary to improve the process of the currently commercially available native sheepskin. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a dual-purpose refitting process for native sheepskin fur and leather, which refits commercially available native sheepskin semi-finished prod...
