ABSTRACT OF THE DISCLOSURE A method of improving the soil-repellant properties of fabrics such as forming fabrics used in paper- making and cellulose machines, and filter cloths used in papermaking and cellulose industries and related industries. The improvement in accordance with the invention is obtained in that the synthetic material from which these fabrics are manufactured, is given improved hydrophilic properties, which in turn is achieved in that the synthetic starting material, prior to being extruded, is mixed with polymers which are made up of monomers having hydrolizable side groups. The fabric manufactured from the synthetic material is treated in a manner known per se with strong bases and/or acids to hydrolize the side groups.
