| Résumé : |
Zirconium oxychloride, with suitable ligand environment has been found to be an effective tanning agent. Hydrothermal stability of about 95°C was obtained for the leathers treated with zirconium oxychloride masked with citric acid. The present investigation focuses on possible methodologies to improve the properties of leathers obtained from zirconium oxychloride tanning to suit different product mix through treatment with various co-tanning adjuncts. Exhaustion of zirconium was found to be greater than 80% in all tanning experiments. The zirconium oxychloride leathers posttanned without neutralization exhibit better organoleptic properties compared to leathers posttanned after neutralization. The post-tanning operations have been optimised to obtain both upper and garment leathers. Treatment of zirconium oxychloride leathers with silica produced fuller and smooth grained upper leathers whereas, pretreatment with gluteraldehyde resulted in soft garment leathers. Properties of the leathers obtained are on par with the conventional chrome tanned leathers. Thus a tanning system based on zirconium oxychloride has the potential to be as versatile as chrome tanning systems, which produce leathers for different end uses. |
