A method for the production of a hydrophilic polymer membrane (1), in particular for the production of a porous membrane for filtration or for use in functional textiles, whereby at least one hydrophilization additive (3) is used as a starting material for the membrane production, optionally, at least one additional aggregate, is/are admixed into an in particular hydrophobic polymer membrane material (2), whereby the membrane material (4) that has the hydrophilization additive (3) and optionally the additional aggregate is extruded to form a polymer film (5) that is charged with the hydrophilization additive (3) and optionally the additional aggregate, and whereby the polymer film (5) is stretched, in particular in a monoaxial and/or biaxial manner for pore formation. |
