Claims (3)
- 연신 폴리아미드 필름을 제조하는데 있어서, 기계방향(MD)의 연신비를 2.3~3.0배, 기계방향(TD)의 직각방향으로 3.0내지 3.5배 연신시키는 단계; 이때 TD/MD 방향의 연신비가 1.1 내지 1.3배이며, 열처리 후 3 내지 10%로 이완하는 단계를 거치는 것을 특징으로 하는 2축 연신 폴리아미드 필름의 제조방법.
- 삭제
- 제1항 기재의 방법으로 제조되며, 130℃의 고온 가압의 물에서 30분간 침지 후 하기식에 따라 측정한 열수수축률이 측정각도 전방향으로 8%이하인 것을 특징으로 하는 2축 연신 폴리아미드 필름.S130(%) = L0-L130/L0×100(식 중 L0는 수출률 측정 전 필름의 길이이고, L130은 130℃의 물에서 30분간 처리한 다음 측정한 길이 임.)
