| Résumé : |
One of the approaches towards minimizing the chrome pollution is to increase the uptake of chromium during tanning through the application of high exhaust basic chromium sulphate slats. A high exhaust chrome tanning salt exhibiting chrome uptake levels of above 82% during tanning has been prepared in our laboratory. The present investigation deals with the influence of high exhaust chrome tanning salt on the hysical, chemical and structural properties of the final leather. The study shows that there is an increasef fixation of chromium to the collagen matrix which in turn influences the uptake of retanning agents, dyes and fatliquors during post tanning operation. This investigation also indicates a realistic saving of 20-25% inpost tanning chemicals when the leathers are tanned with high exhaust BCS salt. |
