Enzyme processing of textiles in reverse micellar solution.
Scouring of cotton using pectinase enzyme, bioscouring, in reverse micellar system was studied. The effectiveness of bioscouring was evaluated by measuring weight loss of cotton, analyzing pectin and cotton wax remaining and by wetness testing. Pectinase enzyme showed excellent activity even in organic media, and the effectiveness of scouring was equivalent or better than that achieved by conventional alkaline process or bioscouring in aqueous media. Enzymatic modification of wool using protease enzyme in the same system was also studied. It has found that felting property and tensile strength of wool fabrics treated by protease in reverse micellar system were superior to those in aqueous media. Possibilities of utilization of the same system for the subsequent textile dyeing process were also investigated. It was found that cotton and polyester fabrics were dyed satisfactorily by reverse micellar system compared to conventional aqueous system.
