Storage and sorting

Before the production process starts, the raw hides (calf skins) are cured with salt and stored in a cool room. After the quality check the hides are sorted according to their weight classes.

Soaking

The process of soaking allows to remove salt and all remaining dirt from the hide. The main objective in soaking the hide is to restore its natural water content.

Fleshing

During the fleshing process the extraneous tissue (flesh, natural grease, fat) is stripped from the surface of the hide.

Liming

Unhairing is done by immersing the hides in a chemical dissolution of lime and sulphide. By doing so, hair is chemically removed from the surface of the hide.

Bating, Pickling, Tanning

During bating and pickling, the hides are treated with acids and salt. This prepares the hides for the addition of tanning agents. The subsequent tanning process is performed with either chrome or vegetable tanning agents. At this point the hide becomes leather.

Splitting

Splitting is done to obtain the desired thickness of the leather. The result of this process is called a split. The split can be processed into velour.

Retannage

To obtain the proper filling, smoothness and colour the leather is neutralised and treated with dyes and grease suitable for its type. By grease treatment the leather becomes softer and water resistant.

Drying

There are two possible ways of drying: vacuum drying and hang drying. The vacuum drying uses pressure to remove the excess of water from the leather, whereas in hang drying, the leather is hanged and dried with hot air.

Staking

The crust, that results after drying is hardened and has to be staked, so it could be subjected to a number of finishing operations later on.

Finishing

Here the suitable operations are employed to add the finishing touch. To achieve the desired type, the leather is pressed, ironed, treated with primers and colouring sets. Depending on the current trends the finish may be shining, matt, one- or multicoloured, smooth or grained.
