Leather Processing and Preparation Stages: An In-Depth Review

Leatherworking is an area that requires both artistic and technical skills. The processing and preparation stages of leather are critical steps that determine the product's quality, durability, and aesthetic value. In this article, we will comprehensively examine the details of the leather processing stages and preparation phases.

  1. Selection and Cleaning of Raw Leather

The leather processing process begins with the selection of high-quality raw leather. At our firm, we use special calf leather; this type of leather offers excellent characteristics in terms of flexibility and durability. Raw leather is sourced fresh and clean. The cleaning process aims to remove meat and fat residues from the leather using mechanical and chemical methods.
