Abstract

A method of obtaining cellulosic fibers or mixtures of these fibers with synthetic fibers characterized by high degrees of hydrophilicity, purification and bleaching, the method of which consists of a treatment with chlorine dioxide, with a small amount of said chlorine dioxide and during a reduced time, followed by hydrogen peroxide or sodium peroxide bleaching performed under known conditions.
