Abstract

폴리에스테르 필름의 제조방법이 개시된다. 무정형, 무배향 또는 종연신 쉬트를 황연신기 내에서 열처리 하면서 연신하는 단계를 포함하는 이축 연신 폴리에스테르 필림의 제조방법에 있어서, 상기 열처리를 적외선 가열기(radiation heater)로 가열하도록 된 방법에 의하면, 필름의 제반 물성이 향상되고 생산 수율을 높일 수 있다.Disclosed is a method for producing a polyester film. According to the method for producing a biaxially stretched polyester film comprising the step of stretching an amorphous, non-oriented or longitudinally stretched sheet in a sulfur stretching machine while heat-treating, according to the method for heating the heat treatment with an infrared heater Its physical properties can be improved and production yield can be increased.
