Abstract

When traditional alkaline scouring of desized cotton fabrics was preceded by cellulase enzymatic treatment, two benefits were observed. Beside significant increase in whiteness of fabrics, enhanced removal and alkaline degradation of seed-coat fragments were achieved. Commercial cellulase enzyme was applied before the caustic scouring process, in 1-10 g/l concentration for 0.5-8 hours at pH 5.0 and at 50°C. Enzyme treatment alone resulted in 14-21 % increase in Berger-whiteness. When consecutive cellulase treatment and conventional alkaline scouring were combined, the increase in whiteness was even more significant. Applying cellulase enzyme in concentrations of 1, 5 and 10 g/l, respectively, in biotreatment followed by conventional caustic scouring, a maximum of 18, 25, and 29 % increase in whiteness was observed. Cellulase pretreatment also allowed the reduction of the hydrogen-peroxide consumption in the chemical bleaching step.
