Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a separator for an alkaline battery having excellent hydrophilic property, liquid-retainability, and high alkali resistance and to provide a manufacturing method for the separator. SOLUTION: This separator is obtained by carrying out wet paper making process of polyolefin type synthesized pulp containing 1.0-10.0wt.% of polyvinyl alcohol after heating treatment at not lower than 100 deg.C and not higher than the melting point of the synthesized pulp in dry condition or by carrying out wet paper making of the synthesized pulp after heating treatment and mixing a polyolefin type thermally melting fibrous binder, drying, and carrying out a thermally melting and depositing process at not higher than the melting point of the synthesized pulp and not lower than the melting point of the polyolefin type thermally melting fibrous binder. |
