The post-tanning stage is made up of further chemical treatments designed to improve the appearance of the leathers and make them suitable for commercial uses. After tanning, the leather still appears rigid and wet and has the colour typical of the tanning process used.
At this stage, the leather is known in the industry as crust, and is resistant and water-repellent. The appropriate finishing processes give it the desired aesthetic characteristics of the finished product, including shine, colour and appearance.
The products used for the post-tanning processes, which include pressing, shaving, retanning, dyeing and fatliquoring, drying, staking, milling and sanding, belong to the following categories: degreasing, retanning, tannins, fatliquors, neutralisers, colourants and resins..
