  2. 제1항에 있어서, 중합체는 파라-방향족 폴리아미드이고, 용액은 광학적으로 비등방성인 방법.
  3. 제2항에 있어서, 파라-방향족 폴리아미드가 폴리(p-페닐렌테레프탈아미드)인 방법.
  4. 제1항에 있어서, 제2속도의 수직선으로 하부 방향인 성분이 제1속도의 제20% 내지 약 99%인 방법.
  5. 제1항에 있어서, 공통선보다 아래로 필라멘트의 방향을 변화시키는 단계를 포함하는 방법.
  6. 제1항에 있어서, 제1속도가 200 내지 2000m/분인 방법.
  7. 제1항에 있어서, 액체의 맞은편 쉬트가 투명한 방법.
  8. 방적돌기면에 직선으로 배열된 구멍을 갖는 방적돌기 ; 및 방적돌기의 반대편에 위치하고, 방적돌기 면에 인접해 있으며, 구멍의 배열이 평행하고 제트 홈이 방적돌기면 바로 아래에 수직으로 공통선과 만날 수 있도록 연장된 한쌍의 직선 제트 몸체를 포함하는 방적돌기 바로밑에 위치한 필라멘트 응고 수단을 포함하는 중합체 용액으로부터 필라멘트를 제조하기 위한 장치.
  9. 제8항에 있어서, 방적돌기의 면에 대해 공통선의 위치가 변하도록 직선 제트 몸체의 위치를 조절하기 위한 수단을 포함하는 장치.
  10. 제9항에 있어서, 공통선이 방적돌기 면 아래에 수직으로 약 1cm 내지 3cm 에 위치하는 장치.
  11. 제8항에 있어서, 공통선에서 제트 홈의 연장사이에 포함되는 각도가 20 내지 60°인 장치.
