Abstract

고강도 나일론 전지 격리판 물질과 이것의 제조방법.
본 발명은 한쌍의 스펀-결합된 나일론 섬유의 웨브사이 샌드위치된 나일론 스테이플 섬유의 비직조형 웨브를 포함하는 적층구조체를 가진 니켈-카드뮴전지내에 사용하기 위한 나일론 전지 격리판 물질에 관한 것이다.
상기 스테이플 웨브는 나일론6와 나일론6-6섬유를 포함한다. 스펀-결합된 섬유는 나일론6-6이다. 제조과정중에 스테이플 웨브는 스펀-결합된 나일론 섬유의 웨브사이 매립된다. 3개의 웨브는 가열된 캘린더 로울의 충적을 통해 통과되는 샌드위치를 형성한다. 충적된 캘린더 로울의 최대온도는 나이론 6섬유의 연화온도 보다 높으나, 나일론6-6섬유의 용융온도보다는 낮다. 냉각과 동시에, 스펀-결합된 섬유의 웨브들은 재-고형화된 나일론 6섬유에 의해 스테이플 웨브에 결합되어, 이로써 적충된 전지 격리판 물질이 형성된다.
