Latest Patents

Mizutani's latest patents include a selectively permeable hollow fiber membrane and a process for producing it. This innovative membrane is designed for blood dialysis and consists primarily of a cellulose derivative. It features a dense layer on the innermost side and a porous layer with a greater void percentage on the outside. The production process involves extruding a spinning solution containing a cellulose derivative dissolved in an organic solvent, while simultaneously introducing a core material solution with a water content of at least 50 wt %. After extrusion, the filamentous body is immersed in a coagulating solution.

Another significant patent is a method for preparing hollow fibers for fluid separator construction. This method focuses on creating hollow fibers with selective permeability, where each fiber has 1 to 10 fins extending longitudinally. The occupancy ratio of the sections of the hollow fibers, exclusive of the fin portions, is carefully defined to optimize performance.
