A continuous method for production of a porous hollow fibre membrane having regioselective affinity for compounds in blood or other biologically active fluids to be removed during purification of blood or said fluids is disclosed, as well as a porous hollow fibre membrane produced by said method, an adsorption device containing such a porous hollow fibre membrane, and use of such a porous hollow fibre membrane.

Continuous method for production of a regioselective porous hollow fibre membrane

A stamping foil for forming printed circuit patterns on insulating or poorly conductive substrates comprising an electrically conductive layer made of a highly conductive metal, such as copper, which is endowed with a sufficiently low shear strength, even in thicknesses of 10 microns or more, to permit easy and sharp separation of the activated (imprinted) and non-activated portions of the foil. Such a low shear strength may be achieved with fibrous or fibrous-granular crystallite structures, wherein the fibers are oriented approximately at right angles to the surfaces of the foil, and, in addition, by doping agents containing carbon, nitrogen and sulfur. The foil may comprise a bonding layer for bonding the conductive layer to a substrate, or such a bonding layer may be applied to the surface of the conductive layer before the stamping operation. The conductive layer may be either self-supporting, or it may adhere to a carrier tape through an intermediary separating layer. In the latter case, the bonding and separating layers become activated when compressed by a stamping die or stereotype, whereby the conductive layer becomes bonded to the substrate and separated from the carrier tape in the activated areas. The activated and non-activated portions of the foil are then separable by pulling the carrier tape away from the substrate.
