Abstract
본 발명은 수축특성이 우수한 폴리에스테르 필름에 관한 것으로, 본 발명의 폴리에스테르 필름은 미소면적의 배향을 조절하여 하기와 같은 조건을 만족하는 배향 특성을 갖는 이축연신 폴리에스테르 필름이다.The present invention relates to a polyester film having excellent shrinkage characteristics, and the polyester film of the present invention is a biaxially stretched polyester film having an orientation characteristic that satisfies the following conditions by adjusting the orientation of a small area.
단, θ: 시료의 MD 방향(필름이 감기는 방향)과 현미경의 분광기 진동방향이 이루는 각.However, θ: angle formed between the MD direction of the sample (the direction in which the film is wound) and the oscillation direction of the microscope spectrometer.
Ⅰ(θ): 편광현미겅에서 분광기와 편광기가 평행인 상태 (평행 니콜)에서의 θ방향의 광투과 강도. Ⅰmax: Ⅰ(θ)중 최대치, Imin: I(θ)중 최소치Ⅰ (θ): The intensity of light transmission in the θ direction in the state where the spectrograph and the polarizer are parallel (parallel Nicole) in a polarizing microscope. Imax: maximum value in I (θ), Imin: minimum value in I (θ)
단, θmax는 Ⅰ(θ)가 I max일때의 θ임.Where θmax is θ when I (θ) is I max.
본 발명에 의해 제공되는 폴리에스테르 필름은 균일한 열수축 특성을 나타내며 1축 방향의 고수축과 직각방향의 저수축을 갖는 수축 특성이 우수하다.The polyester film provided by the present invention exhibits uniform heat shrinkage characteristics and is excellent in shrinkage characteristics having high shrinkage in the uniaxial direction and low shrinkage in the perpendicular direction.
