A permeability separatory device including a shell element that retains a woven mat wound into a roll and composed of a woof portion formed by a plurality of substantially parallel hollow membrane fibers having open inlet and outlet ends so as to provide parallel fluid flow paths and a plurality of warp portions formed by strands of yarn woven transversely to the hollow fibers so as to establish predetermined interstitial spacing therebetween. The open ends of the hollow fibers are sealed from a fluid circulation zone defined by the shell and retaining the wound roll. Also defined by the shell element are inlet and outlet openings for circulating a dialysate fluid through the circulation zone and over the surfaces of the hollow fibers. The warp portions of the woven mat include one warp portion for establishing at one end of the wound roll a given restriction to fluid flow axially therethrough and another warp portion for establishing at an opposite end thereof a greater restriction to fluid flow. An additional warp portion is formed by yarn woven obliquely to the hollow fibers and extends between opposite ends of the wound roll.
