| Résumé : |
Higher temperatures favour chrome fixation, a conclusion reached on the basis of practical observations, laboratory and small scale trials. This phenomenon has now been investigated on the strength of an analysis of full scale commercial production of leather over an extended period of time. Part 1 : The effect of temperature on chrome uptake |
