Abstract: The invention relates to a process for treatment of cellulosic material, as for example, knitted or woven cotton fabric, comprising the steps of preparing an aqueous enzyme solution comprising pectinase, treating the cellulosic material with an effective amount of the aqueous enzyme solution under alkaline scouring conditions; e.g., pH of 9 or above and a temperature of 50null C. or above, in a low calcium or calcium-free environment, yielding a modification of the cellulosic material such that exhibits an enhanced respond to a subsequent chemical treatment.

Abstract: The present invention provides methods for single-bath biopreparation and dyeing of cellulosic fibers, which are carried out by contacting the fibers simultaneously or sequentially with a bioscouring enzyme, preferably pectinase, protease, and/or lipase, and a dyeing system, under conditions that do not require emptying the bath or rinsing the fabric between biopreparation and dyeing steps.
