Non-woven fabric for alkaline battery separator and manufacturing method thereof

The non-woven fabric for an alkaline battery separator is a dicarboxylic acid component containing 60 mol% or more of the dicarboxylic acid component and an aliphatic dicarboxylic acid component, and 60 mol% or more of the diamine component is a fat having 6 to 12 carbon atoms. A nonwoven fabric for an alkaline battery separator comprising a semi-aromatic polyamide fiber composed of a diamine component of an alkylene diamine and an ethylene-vinyl alcohol copolymer fiber, wherein the nonwoven fabric has a specific gravity of 1.30 at 90 ° C. In the alkali resistance test in the KOH aqueous solution, the nonwoven fabric for an alkaline battery separator having an excellent alkali resistance of 5% or less of the nonwoven fabric for a separator after 20 days passed. Therefore, it can be applied to a non-woven fabric for an alkaline battery separator which can be charged quickly, has a large current discharge, has a high capacity, and has a small thickness.
