Claims (6)
- 폴리에스테르 부분연신사(POY)를 제조함에 있어서, 통상의 폴리에스테르중합체에 폴리에스테르 분자의 배향/결정화 억제성능의 제 2 성분을 혼합시켜서 4,000 ∼ 6,000m/분의 방사속도로 용융방사, 부분연신하되, 제 2 성분의 혼합농도가 큰 것은 심층부(Core)에, 제 2 성분의 혼합농도가 적은 것은 표층부(Sheath)에 오도록 표층/심층 복합방사 팩장치로 복합방사하여 잔유신도가 100 ∼ 180%가 되도록 제조함을 특징으로 하는 폴리에스테르 부분연신사의 제조방법.
- 폴리에스테르 부분연신사로서, 심층부(Core)에는 통상의 폴리에스테르 중합체에 배향/결정화 억제성능을 가진 제 2 성분이 고농도로 함유되어 있고 표층부(Sheath)에는 통상의 폴리에스테르 중합체에 상기 제 2 성분이 저농도로 함유되어 있으며, 표층부(Sheath)의 면적비율이 심층부(Core)의 면적비율 보다 현저하게 큰 것을 특징으로 하는 폴리에스테르 부분연신사.
- 제 2 항에 있어서, 폴리에스테르 중합체 대비 제 2 성분의 심층부에서의 농도는 0.4 ∼2.0중량%이고, 표층부에서의 농도는 0.1 ∼ 0.5중량%임을 특징으로 하는 폴리에스테르 부분연신사.
- 제 2 항에 있어서, 표층부의 면적비율은 70 ∼ 90%, 심층부의 면적비율은 30∼ 10%임을 특징으로 하는 폴리에스테르 부분연신사.
- 제 2 항에 있어서, 제 2 성분은 비결정성이고 통상의 폴리에스테르 중합체에 대하여 비상용성이며, 유리전이온도가 80 ∼ 120℃인 열가소성 폴리머임을 특징으로 하는 폴리에스테르 부분연신사.
- 제 5 항에 있어서, 제 2 성분은 폴리메틸메타아크릴레이트, 폴리스틸렌, 폴리카보네이트 등에서 선택한 것임을 특징으로 하는 폴리에스테르 부분연신사.
