| Résumé : |
Under conditions of constant pH and temperature during chrome tannage, those parameters do not have equivalent stabilising effects on the leather. Higher tanning temperature accelerates chrome exhaustion, but shrinkage temperature is influenced more by the pH of tannage.
The resistance of chrome leather to boiling water depends not only on the conventionally measured shrinkage temperature, but also on how it was reached, particularly with regard to the ageing conditions following tannage. The minimum shrinkage temperature required for a dry leather to survive 5 minutes in boiling water is 110°C; a lower value can be sufficient, but only if the processing includes ageing at elevated temperature.
