ABSTRACT:
A cation exchanger in paper-like or felt-like form is obtained by making a fibrous sheet from a blend of polyethylene fibers into which sulfonic groups have been introduced with 0.1 to 50% by weight of thermoplastic resin fibers and heating the sheet at the softening temperature of said thermoplastic resin or higher temperatures. This cation exchanger is useful in softening or desalination of raw water, separation and recovery of various metals, and adsorption of basic dyestuffs and cationic dyestuffs.
