A Novel Stabilization of Skin Protein Using Replenishable Tanning Agents – Mineral-free Fragrant Garment Leathers

ABSTRACT

Conventionally leathers are produced from chromium tanning which is toxic and difficult to dispose off the chromium containing wastes and products. However, to date there hasn’t been any replacement found for chromium as a preferred tanning agent for the leather industry due to the hydrothermal characteristics and versatility of chromium. This study aims to produce mineral-free unlined garment leather made out of aldehyde and oil tanning with the inherent properties of aroma and anti-fungal. Glutaraldehyde along with sperm oil and jatropha oil have been employed and compared with conventional chrome tanning processes. The performance of experimental leathers concerning physical and bulk properties is suitable for garment manufacturing. Studies of Solid state NMR, the effect of tanning agents on collagen are confirmed. Morphological studies using Scanning electron microscopy revealed that experimental leathers exhibited better lubrication and opened-up fiber structure. Resistance to fungal species is substantial with combination tanning system as conventional processing using synthetic biocides poses severe health hazards and safety concerns. Here we demonstrate that aldehyde and oil combination tanning technology generates significantly less toxic waste and has economic potential for commercial implementation.

摘要

传统的皮革是用铬鞣法生产的, 铬鞣法有毒, 难以处理含铬废物和产品. 然而, 由于铬的水热特性和多功能性, 迄今为止还没有发现铬作为皮革工业首选鞣剂的替代品. 本研究旨在以醛鞣和油鞣为原料, 制备具有香气和抗真菌特性的无矿物质无衬里服装革. 采用了戊二醛, 精油和麻疯树油, 并与传统的铬鞣工艺进行了比较. 实验皮革的物理和体积性能适合服装制造. 固态核磁共振研究证实了鞣剂对胶原蛋白的影响. 利用扫描电子显微镜进行的形态学研究表明, 实验皮革表现出更好的润滑性和开放的纤维结构. 由于使用合成杀生物剂的传统加工带来了严重的健康危害和安全问题, 因此使用组合鞣制系统对真菌种类的抗性很强. 在这里, 我们证明了醛和油结合鞣制技术产生的有毒废物明显较少, 并且具有商业化实施的经济潜力.
