| Résumé : |
An organic combination tanning process for the production of upper leathers based on henna and glutaraldehyde was demonstrated in this work. Extract from the leaves of Henna (Lawsonia inermis), widely distributed in Sudan, has been evaluated for its utilization in the combination tanning system based on henna and glutaraldehyde syntan. It was observed that the henna-glutaraldehyde combination tanning system employing 20% Henna extract and 3% Glutaraldehyde syntan provided a shrinkage temperature of 100°C. The Differential Scanning Calorimetric (DSC) data is in accordance with the observed shrinkage temperature. The characteristics of the leathers indicate that the henna-glutaraldehyde combination tanning system provided leathers with good organoleptic properties and comparable strength properties. The leathers were further characterized by chemical analysis and Scanning Electron Microscopy (SEM). The leathers obtained from the combination tanning system were lighter in color compared to control leathers as observed from the color measurement. Thus the possibility of making upper leather using henna-glutaraldehyde combination tanning appears to be promising. |
