Abstract

Environmental issues are nowadays the prime concern worldwide for leather industries due to chrome containing solid and liquid wastes generated from the tannery. Therefore, experts are being encouraged in exploring alternative tanning agents. This study aimed at applying a novel vegetable tanning agent extracted from Xylocarpus granatum barks for the production of semi-chrome (SC) and chrome retanned (CR) leathers to reduce chromium use. Characterization of the SC and CR leathers was performed by Fourier Transform Infrared (FTIR) spectroscopy which revealed prominent tanning activity of the extracted tannins. The tanned leathers exhibited shrinkage temperatures of 112˚C for SC and 103˚C for CR leathers. The physicomechanical properties were found as tensile strength >230 kg/cm2, tear strength >30 kg/cm, grain cracking load >20 kg, distention at grain crack >7 mm, ball bursting load >38 kg, and distention at ball bursting >12mm that was comparatively acceptable according to UNIDO standard for shoe upper leathers.

从石榴木中提取的植物基植物鞣剂在半铬和铬复鞣革生产中的应用

由于制革厂产生的含铬固体和液体废物，环境问题是当今世界皮革工业最关心的问题。因此，鼓励专家们探索替代的晒黑剂。研究了从木皮中提取的一种新型植物鞣剂，用于生产半铬革(SC)和再鞣革(CR)，以减少铬的使用。用傅里叶变换红外光谱对SC和CR皮革进行了表征，发现提取的鞣质具有显著的鞣制活性。鞣革的收缩率为SC革112℃，CR革103℃。其物理力学性能为抗拉强度>230 kg/cm2，撕裂强度>30 kg/cm，颗粒开裂载荷>20 kg，颗粒开裂膨胀>7 mm，破球载荷>38 kg，破球膨胀>12mm，符合联合国工业发展组织鞋面革标准。
