| Résumé : |
Presently, there is rising demand for the manufacture of chrome-free leathers. In this work, an attempt has been made to manufacture chrome-free garment leathers using a combination tannage based on tara tannin and co-tanning adjuncts viz., aluminum and gluteraldehyde. The shrinkage temperature of leathers using different combinations of tara and aluminum/ gluteraldehyde were found to be around 90oC. Tara-aluminum combination tanning system resulted in leathers with less softness and grain smoothness compared to tara-gluteraldehyde combination tanning system. The order of addition of gluteraldehyde had a significant influence on the organoleptic properties of the leathers. Gluteraldehyde pretreatment of tara tanned leathers gave better results when compared to post treatment. Tara at the 8% level was found to be optimum for combination tanning using 2% gluteraldehyde pretreatment. The gluteraldehyde-tara tanning system resulted in white leathers compared to the undyed chrome tanned crust leathers. The physical, organoleptic, dyeability and finishing characteristics of the crust leathers from both control and gluteraldehyde-tara tanning were comparable. |
