Abstract

PURPOSE:To produce a thin, asymmetric membrane of high water permeability by making a solution of reverse osmotic material flow into a net such as rough plain fabrics so as to wrap the net in the solution to form integrated membrane, and by making the membrane at the centers of metwork less thick than the membrane on the filaments and on the cross points of the filaments.
