Abstract
A leno-woven fabric of a specific construction is found to effectively reinforce an ion-exchange membrane at a scarce density of reinforcing yarns to improve electrochemical property of the reinforced ion-exchange membrane.
Claims5
In a reinforced ion-exchange membrane comprising a fabric embedded in said ion-exchange membrane, the improvement which comprises using as the fabric a leno-woven fabric with a weave structure in which the numbers of warp yarns are in the range from 16 to 28 per one centimeter of width and those of filling yarns in the range from 8 to 14 per one centimeter of length, the square root of the denier divided by specific gravity of said warp yarn being in the range from 6 to 11 and that of said filling yarn in the range from 8 to 16.
