| Résumé : |
The reasons for investigating chrome-free tannages are discussed, the main one being the increasing problem of the disposal of chrome-containing effluents. Various chrome-free tannages are reviewed and the history of combination vegetable/aluminium (i.e., semi-alum) tannages is discussed. A promising semi-alum tannage known as the Mimosal-Al process is the main topic of the paper. The process consists of a low mimosa pretannage, followed by a basic aluminium sulfate retannage, giving a boil-proof leather with a kind handle and good dyeing, buffing, and printing properties.
The theory of the Mimosa-Al process is discussed and it is postulated that aluminium ions form complexes with the already bound mimosa tannins and so give stable crosslinking. The development of the process is also outlined and it is shown that the optimum levels of mimosa extract and aluminium are offers of 15 percent mimosa and 6.5 percent aluminium sulfate, on the limed weight. A typical Mimosa-Al process is given and various important aspects of the process are discussed. |
