Abstract

The invention provides a leather treatment technology used for solving the problem that the leather treatment efficiency is low. The leather treatment technology comprises the following steps that fixing is conducted, specifically, the two corresponding ends of leather are fixed to leather clamps, and at least two pieces of leather are fixed to each leather clamp; pre-soaking is conducted; soakingis conducted; pretreatment is conducted; depilation is conducted; swelling is conducted; dealkalizing is conducted; softening is conducted; and pickling is conducted. The leather is fixed to the leather clamps, the leather can be prevented from being rolled into a ball during rotating, the contact degree between the leather and a cleaning chemical liquid is improved, and the leather treatment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of leather processing, and relates to a leather processing technology. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tannin. It has natural grain and luster, and feels comfortable. It is used in leather applications such as household leather. [0003] A drum is a rotary device in which raw hides are turned inside (such as for washing, pickling, tanning, dyeing) or for cleaning furs inside (by turning together with fine sawdust) during the tanning process. It is an important equipment widely used in tanneries , when driven by the motor, the leather in the drum is subject to mechanical actions such as bending, stretching, smashing, stirring, etc., which speeds up the chemical reaction process and changes the physical properties of the leather. The application range of the drum covers most of the wet pro...
