| Résumé : |
The introduction of the two-bath process was the subject of a recent paper by Stellmach. No less revolutionary was the shift in the one-bath tannage from chrome alum to basic chrome salts. The suppliers of these chrome extracts became adept at modifying them to save the tanner time and nearly to eliminated the chrome content of waste liquors. These and other changes taking place in the manufacture of leather induced governments and institutes devoted to research and engineering and to open national tanners' schools. International and national societies formed and bagan to hold annual or biennal conventions. Periodicals were founded, spreading the latest word on theory and practice of converting hides and skins into leather. These developments are reviewed with particular emphasis on the United States. Promising new technologies including "reconstitued collagen", solvent tannages and various ultra-rapid methods aimed at reducing sludge and effluent to a minimum are surveyed. Several synthetic tanning materials born out of necessity in Germany and the US during World War Il could not maintain as large a share of the market as was necessary for them to be produced in peacetime. Finally, the most recent trend toward the partial or complete elimination of chrome, for instance by replacing wet blues with aluminum-tanned wet whites, is briefly discussed. |
