| Résumé : |
A new sulphonated melamine-urea-formaldehyde (MUF) resin of relatively low melamine content, prepared according to a sequential procedure, has been shown to be highly effective when coupled with different natural vegetable tannins to produce leather with the same good characteristics of leather prepared with chrome salts. In particular the shrinkage temperature of the leather prepared according to the new approach is comparable to that obtained with chrome-tanned leathers. Leathers produced using tanning formulations based on the combination of this MUF resin with either flavonoid (condensed: mimosa or quebracho) tannins and hydrolysable ellagitannins (chestnut) have shown good colour stability. Leathers prepared with Chestnut or Mimosa combined with MUF tannage in 50/50 and in 75/25 weight ratios exhibited the most promising physical properties. Furthermore, there are a number of other formulations to choose from which are capable to overcome the major drawback of vegetable tanning in relation to chromium tanning. |
