Washing-resistant cow clothing leather processing technology

Abstract

The invention discloses a washing-resistant cow clothing leather processing technology, and relates to the technical field of cow leather clothes. The washing-resistant cow clothing leather processingtechnology specifically comprises the following steps of 1, carrying out batch soaking, namely classifying the raw leather with the similar thickness, and placing raw leather in a drum to be processed, and adding clear water into the drum for soaking the raw leather, soaking the dried leather for 2-3 days, soaking wet salted hides for 1-2 days, adding an immersion aid in the soaking process, andaccelerating the soaking of water; 2, performing hair removal and degreasing, removing the grease on the surfaces of the cells in the cow leather and the hair on the surface of the original leather byusing a depilating machine after being soaked in the step 1 to expose the natural and fine grain surfaces; and 3, soaking the leaching acid, soaking Ca(OH)2 with the mass fraction being 10% for 1-2 hours, and expanding the cow leather to a certain thickness. According to the washing-resistant cow leather processing technology, the processing technology is simple and comprehensive, the water washing resistance of the cow leather is greatly improved by the adoption of the chrome tanning agent, so that the problem that the cow leather becomes dry and hard after being cleaned for multiple times is avoided.

Description

technical field [0001] The invention relates to the technical field of cowhide garments, in particular to a process for processing washable cowhide garment leather.
