Reduction of the Salt Freight in Tannery Effluent
In our modern, industrialised society responsibility for active environmental protection is already one of the most important aspects. Not surprisingly environmental awareness has grown immensely in leather production as it has elsewhere too. Tough official regulations governing effluents, waste air and solid waste disposal provide the legislative background to this increased environmental sensitivity. To meet the specified limit values products and application methods must measure up to stringent requirements. Optimum exhaustion of products, environmental compatibility of the by-products formed and avoidance of waste are very important. Compliance with stricter effluent legislation and landfill regulations are difficult challenges to both the leather industry and the industry supplying it with chemicals. In a modern, look-ahead tannery, environmental protection is therefore every bit as important as leather quality, productivity and profitability.

While a considerable amount on dyes and dyeing properties has been written over time it has often been out-dated due to new legislation or tannery needs in terms of leather performance. Here we will attempt to bring together the ideas regarding leather dyes as used today and how the structural properties influence the performance properties. The theory being that if one needs specific fastness characteristics one can then use the structure that best meets these needs.
An overview of the future trends in dyes and the properties they will need to fulfil will also be presented.
