Abstract
- Laccase-catalyzed synthesis of dye molecules represents a green choice to reduce the environmental footprint of conventional synthetic processes. Textile industry will benefit from this green technology since the synthesized dyes can be exploited to colour different fabrics. This work describes the application of the Pleurotus ostreatus POXA1b laccase in polymeric dye synthesis using resorcinol and 2,5-diaminobenzenesulfonic acid (2,5-DABSA) as substrates. The potential of the resorcinol/2,5-DABSA coupling route was transferred to a chemical industry, Setas Colour Center, by introducing a greener synthesis step within the process routinely used for textile dyeing. Dye synthesis was performed at different precursor ratios (1:1 and 1:10 2,5-DABSA: resorcinol) and their dyeing properties were compared on different fibres. The two mixtures of synthesized dyes proved to be effective on nylon and wool, with 1:10 ratio displaying the best performances in terms of dyeing efficiency and colour strength. Good and comparable end quality and “performances during use” were observed for nylon and wool coloured with both synthesized dyes.
