Abstract

Based on a novel triazine compound, the properties of tanned leather and commercial feasibility in pilot scale have been investigated. Then this novel approach tanning was compared with conventional chrome tanning: in the condition of less-salt pickling and chrome free, the physicochemical properties including thermal stability and mechanical strength were analyzed. Meanwhile, the surface roughness and fiber dispersion were evaluated as well. The results show that the thermal stability and mechanical strength of the triazine compound tanned leather are similar to conventional chrome tanned leather, the fiber bundle is well-dispersed and much evener than that of chrome treating. The optimized tanning approach has obvious reduction in environmental impact and leads an excellent biodegradability of tanning liquor. In industrial application, the cost of materials and water treatment are reduced effectively. The production of chrome free leather can encourage the sustainable development of leather industry and protects ecological environment in some extent.
