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

The invention provides a non-woven fabric for alkaline battery separators, which contains a dicarboxylic acid component composed of 60 mol% or more of a dicarboxylic acid component and an aromatic dicarboxylic acid component and a 60% or more carbon number of 6 to 6 12. A nonwoven fabric for alkaline battery separators composed of semi-aromatic polyamide fibers and ethylene-vinyl alcohol copolymer fibers composed of the diamine component of the aliphatic alkylene diamine. ．In the alkali resistance test in 30 KOH aqueous solution, the weight loss rate of the separator nonwoven fabric after 20 days is less than 5%. It is an excellent alkali resistant alkaline battery separator nonwoven fabric. Therefore, it can be applied to non-woven fabrics for alkaline battery separators that can be quickly charged and discharged with large current, increased in capacity, and thin in thickness.
