| Résumé : |
There was a time when the saying that leather is made in the beamhouse largely applied. This may be true for some classic type chrome leathers such as box-calf or some gloving beather, but for the large volume of bovine leather this no longer applies. Today, beamhouse and the primary chrome tannage is kept uniform, and the major variations are made by neutralisation, retanning and fatliquoring. This applies to leathers for footwear, leather goods and eveb upholstery, and in this respect retanning plays an important role.
However, times are changing and combination tannages are being used more frequently to obtain certain leather properties or to avoid specific tanning materials. Since specific properties often cannot be achieved by using just one single tanning material, these combinaisons will be more frequent in the future. Today's changing needs have resulted in a more diverse use of products, and terms such as pre-conditioning, pretannage, main tannage and retannage often need clearer differentiation.
While special tannages such as oil tannages are clearly defined, combinaison tannages need a better explantation, and this in turn requires the role of retannage to be considerered. |
