| Résumé : |
Various aliphatic carboxylic acids and hydroxy-acids, aromatic carboxylic acids and phenols have been evaluated as masking agents for potential application in a solo aluminium sulphate tannage to replace conventional chromium tanning. Lamb intestine was used as the source of collagen and tanning effectiveness was assessed primarily by measurement of shrinkage temperature (Ts).
The importance of the presence and position of carboxyl and hydroxyl groups in both aliphatic and aromatic compounds has been demonstrated.
Phthalate is the most promising masking agent for the production of white aluminium tanned leather while ketomalonate, mucate, 2,4-dihydroxymandelate and gallate also produced useful increases in shrinkage temperature.
Citrate was confirmed as the stongest aliphatic complexing agent for basic aluminium sulphate and 2,3-dihydroxybenzoate was shown to be the strongest aromatic complexing agent.
The covalent introduction of these or related carboxylates into collagen is suggested as a means of increasing the effectiveness of aluminium tannage. |
