Abstract (en)

[origin: WO03002810A1] The present invention provides methods for single-bath desizing, scouring and bleaching of cellulosic materials, which are carried out by contracting the cellulosic simultaneously or sequentially with an enzyme system and a peracid bleaching system under conditions that do not require emptying the bath or rinsing the cellulosic materials between desizing, scouring and bleaching steps.
