FIBER USING OLEFIN RESIN, NONWOVEN FABRIC USING SAME, AND SEPARATOR FOR ALKALI STORAGE BATTERY |
摘要 |
There is provided a low-cost alkaline storage battery separator capable of implementing stable fiber spinning and excellent ammonia trapping function so as to control self-discharge. Spinning fiber using resin including 1.0 mass % or greater of low crystalline polyolefin, crystalline polyolefin and maleic anhydride-modified polyolefin corresponding to a maleic anhydride component content of 3.5 to 35 mass % in the fiber assures stability during fiber spinning. Moreover, making a nonwoven fabric using the fiber act as a separator allows a high level of ammonia trapping function and controls self-discharge of the alkaline storage battery. |
