Utilization of Acacia seyal(Talih) bark powder Extract for Manufacture of Upper leather as Alternative Retanning Agent

Abstract

This study was conducted at Alfula area which located at longitude 20-28 south and latitude 11-43 north the over all objective of this study were to fill the looser and softer parts of leather in order to produce leathers of more uniform physical properties. This is to investigate that the process will allow for the production of unlined footwear, to improve on the chemical stability of the leather, prompt rapid finishing and delivery to the customer. The plant has been evaluated and reported for application in the retanning of the leather. The process involves extracting the barks of Acacia seyal (Talih) for 1 hour with distilled water (1:10 w/v) at temperature above 80˚C. The Talih extract once was applied during prepared the retanning of wet blue leathers. To determine The efficacy of the pontency and effectiveness of the Acacia seyal (Talih) and extract during the retanning of wet blue leathers when the control and experimental retannage methodologies was applied was determined. The result of Acacia seyal (Talih) retanned compared to Acacia pycnantha(Wattle) retanned leathers. Acacia seyal (Talih) showed good grain tightness and retanned leathers were found to be better than Acacia pycnantha(Wattle) retanned. Further analysis of physical characteristic tests indicated that it can be used as an alternative retanning material.
