Tanning Process Pre-Production Beginning with the raw material, the first cycle is liming (removing the hair) and fleshing (removing the fat), followed by tanning, (using agents to stabilize the leather). These are all done in large drums. Excess liquid is removed by pressing the hide (slamming) so that it is ready to be uniformly shaved to predetermined thickness (splitting).
Finishing The hides are then rotated in wooden drums and filled with water-based aniline dyes which permeate each hide from back to front. After being removed from the dyeing vats and air dried, the hides are soaked and returned to the drum for additional dyeing.
Hides with visible defects may be buffed, or lightly corrected to eliminate those defects.
Some hides may then go into the finishing stage to receive texture or other special characteristics such as antiquing, savaging, or distressing.
Some hides may also have an additional coating of protective agents or may even be embossed for a special appearance.
Pure aniline dyed leather has no correcting. Therefore the natural beauty of the hide is evident and only enhances the look of an untreated leather.
