| Résumé : |
Pickle-less vegetable tanning is becoming vital to the tanners due to environmental problems. In this investigation an attempt has been made to tan goatskins using commercially available vegetable tanning agent (wattle) at pH 8.0-8.5. In order to have a comparative study, partial pickling to pH 4.5 has also been performed as a control. There is no surface deposition of vegetable tannin in the experimental leathers although vegetable tanning has been carried out at higher pH. This has been substantiated through scanning electron microscopic analysis. The exhaustion of vegetable tannin is higher in the case of the experimental process. The experimentally processed leather shows slight improvement in hydrothermal stability compared to conventionally processed leather. Performance of the leathers is shown to be on par with conventionally tanned leathers through physical and tactile evaluation. Color measurement studies show that the variation in color or shade between control and experimental leather is negligible. The process also enjoys reduction in total solids, chloride and chemical oxygen demand (COD) loads by 73, 97 and 19 %, respectively from the identified streams. |
