Assessment of the Dyeing Properties of the Pigments Produced by Talaromyces spp.
AbstractThe high production yields of pigments by Talaromyces spp. and their high thermal stability have implied that industrial application interests may emerge in the food and textile industries, as they both involve subjecting the colourants to high temperatures. The present study aimed to assess the potential application of the pigments produced by Talaromyces spp. in the textile area by studying their dyeing properties. Dyeing studies were performed on wool. The dyeing process consisted of three stages: scouring, mordanting, and dyeing. Two different mordants (alum, A; ferric chloride, F) were tested at different concentrations on fabric weight (A: 5, 10, 15%; F: 10, 20, 30%). The mordanting process had a significant effect on the final colour of the dyed fabrics obtained. The values of dyeing rate constant (k), half-time of dyeing (t1/2), and sorption kinetics behaviour were evaluated and discussed. The obtained results showed that pigments produced by Talaromyces spp. could serve as a source for the natural dyeing of wool textiles. View Full-Text
