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

A non-woven fabric for alkaline battery separators, which is composed of 60 mol% or more of dicarboxylic acid components as aromatic dicarboxylic acid components and 60 mol% or more of diamine components as carbon number 6-12 fats A nonwoven fabric for alkaline battery separators composed of semi-aromatic polyamide fibers and ethylene-vinyl alcohol copolymer fibers composed of diamine components of alkylene diamine. The nonwoven fabric has a specific gravity of 1.30 at 90 ° C In the alkali resistance test in the aqueous solution of KOH, after 20 days, the weight reduction rate of the nonwoven fabric for separators is 5% or less, which is an excellent alkali resistant nonwoven fabric for alkaline battery separators. 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.
