摘要：PURPOSE:To manufacture a battery separator with excellent electrolytic affinity by sulfonation-processing woven or unwoven cloth made of olefin series resin and immersing it in alkaline aqueous solution of a high concentration. CONSTITUTION:Woven or unwoven cloth made of olefin series resin is sulfonation-processed by immersing it in a fuming sulfuric acid or a heat concentrated sulfuric acid. Then the affinity to an electrolyte is increased by cleaning the cloth by water, immediately immersing it in aqueous solution such as NaOH and KOH of a high concentration, and forming a sulfonic radical connected to an olefin into alkaline salt.
