摘要： The present invention provides a non-woven fabric for an alkaline battery separator comprising semi-aromatic polyamide fibers comprising 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; wherein, the separator non-woven fabric has superior alkaline resistance in which the weight loss rate after 20 days is 5% or less in an alkaline resistance test at 90° C. in aqueous KOH solution having a specific gravity of 1.30. Consequently, since the present invention enables rapid charging and large-current discharging while also allowing thickness to be reduced for higher capacity, it can be preferably used as a non-woven fabric for an alkaline battery separator.
摘要翻译：本发明提供一种碱性电池隔板用无纺布，其包含半芳族聚酰胺纤维，其包含二羧酸成分，其中，二羧酸成分为60摩尔％以上为芳香族羧酸成分，二胺成分为二羧酸成分，其中，二胺成分为60摩尔％以上为碳原子数为6〜12的脂肪族亚烷基二胺和乙烯/乙烯醇共聚物纤维，其中，在比重为1.30的KOH水溶液中，在90℃下的耐碱性试验中，隔离层无纺布具有优异的耐碱性，其中20天后的重量损失率为5％以下。因此，由于本发明能够进行快速充电和大电流放电，同时还可以降低较大容量的厚度，因此可优选用作碱性电池隔板的无纺布。
