Non-woven fabric for alkaline battery separator and method for producing same

The present invention provides a non-woven fabric for an alkaline battery separator, which comprises 60 mol% or more of a dicarboxylic acid component and a diamine component containing 60 mol% or more of a dicarboxylic acid component as an aromatic dicarboxylic acid component, and a carbon number of 6 to A semi-aromatic polyamide fiber composed of a diamine component of a fatty alkylene diamine of 12, and a non-woven fabric for an alkaline battery separator of an ethylene-vinyl alcohol copolymer fiber having a specific gravity at 90 ° C In the alkali resistance test in the KOH aqueous solution of .30, 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 quickly charged and discharged with a large current, has a high capacity, and has a small thickness.
