The invention relates to a process for increasing the strength of high-permeability capillary hollow membranes made of regenerated cellulose by the viscose process. These hollow membranes are particularly suitable for blood detoxification. In accordance with the invention, hollow membranes increased in strength are obtained when they are treated after shaping with detergents containing additives of O- and / or OH-containing neutral, substantially non-volatile, water-soluble organic substances.
