Results

Our research group has been working with enzymes in textile processes for more than ten years. In the frame of the present research project our primary research interest was in the area of biopreparation with special emphasis on cotton fabric. Enzymatic biopreparation of cellulosics is an environmentally-friendly alternative to the conventional alkaline scouring for removing the non-cellulosic “impurities” (i.e. waxes, pectins, proteins, lignin-containing impurities and colouring matters, etc.) from greige fibres. Our research thrusts covered the application of commercial hydrolytic enzymes, such as cellulases, pectinases and xylanases for biopreparation of cotton and linen fabrics and their blends; the intensification of bioscouring with chelating agents; the evaluation of the degradation and removal of non-cellulosic matters, especially waxes and cotton seed-coat fragments; the characterization of the dyeing properties of the biopretreated fabrics, as well as the production of oxidative microbial enzymes by solid-state fermentation for efficient degradation of lignin-containing impurities of cotton and linen substrates. Based on the knowledge and experience came from the research supported by the OTKA for many years, implementation of biopreparation and biofinishing technologies in the finishing process of cotton, cotton/linen and cotton/hemp knitted fabrics was realized in 2005 and 2006, respectively, in the frame of a research & development project.
