Process leather is a job that involves treating animal hides to make them suitable for use in clothing, furniture, and other items. The process involves soaking the hide in a solution of water and chemicals, then stretching it on a frame and drying it. The tanning process, which is the first step in the process, involves using a chemical called tannin to preserve the hide and make it more durable. After the hide has been tanned, it is then dyed, oiled, and finished with a protective coating.
