Patent ID: 7405172

Claim:
A non-woven fabric for an alkaline battery separator comprising a non-woven fabric prepared by a wet papermaking method, which contains semi-aromatic polyamide fibers, prepared from a dicarboxylic acid component in which 60 mol % or more of the dicarboxylic acid component is an aromatic carboxylic acid component and a diamine component in which 60 mol % or more of the diamine component is an aliphatic alkylene diamine having 6 to 12 carbon atoms, and ethylene/vinyl alcohol copolymer fibers having an ethylene content of 20 to 70 mol % as a binder fiber having hygrothermal adhesiveness, wherein the separator non-woven fabric has an alkaline resistance in which the weight loss rate after 20 days is 5% or less in an alkaline resistance test at 90° C. in an aqueous KOH solution having a specific gravity of 1.30.
