The leather industry holds a significant place in the global economy, yet the scarcity of raw hides and skins, growing ethical concern, competitive leather substitutes and regulation of manufacturing processes with adverse environmental effects restrict the expansion of the leather industry. These issues may be partly solved by nanotechnology to add innovative products and to treat tannery effluents. This article reviews research gaps of conventional leather manufacturing processes including curing, tanning, and effluent treatment using nanotannage, photocatalysts and filtration. Nanomaterials have been applied at various stages of leather manufacturing to achieve better performances.

皮革行业在全球经济中占有重要地位，但生皮和皮革的稀缺，道德问题日益严重，具有竞争性的皮革替代品以及对生产过程的监管对环境产生不利影响，限制了皮革行业的发展。这些问题可以通过纳米技术部分解决，以添加创新产品并处理制革厂废水。本文回顾了常规皮革制造工艺的研究差距，包括使用纳米鞣剂，光催化剂和过滤的硫化，鞣制和废水处理。纳米材料已应用于皮革制造的各个阶段，以实现更好的性能。
