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.
