ABSTRACT:
In one aspect a woven diaphragm for use in an electrolytic or in an electrochemical cell. The diaphragm is woven with yarns made from synthetic hydrophobic staple fibers having a linear density between about 1 and 10 denier. The diaphragm is between about 0.005 and 0.150 inches thick and has a weight between about 0.1 and 3.0 pounds per square yard. The diaphragm provides desirable ionic and hydraulic flow rates and a desirable cross cell voltage differential in operation of the cell.
