Abstract
본 발명은 텐터를 이용하여 이축연신 열가소성수지 필름을 제조함에 있어서, 텐터의 횡연신 공정에서 횡연신된 필름을 하기 일반식(Ⅰ)을 만족하는 길이를 갖는 유리전이온도 이하의 냉각영역에서 냉각하고 하기 일반식(Ⅱ)을 만족하는 온도와 하기 일반식(Ⅲ)을 만족하는 길이를 갖는 열고정 영역에서 열고정시켜 이축연신 열가소성수지를 제조하였다.In the present invention, in manufacturing a biaxially stretched thermoplastic resin film using a tenter, the film stretched in the transverse stretching process of the tenter is cooled in a cooling region below the glass transition temperature having a length satisfying the following general formula (I). A biaxially stretched thermoplastic resin was prepared by heat setting in a heat setting region having a temperature satisfying General Formula (II) and a length satisfying General Formula (III).
LC> LHS(Ⅰ)L C > L HS (Ⅰ)
여기서, LC텐터내의 냉각 영역의 길이이고, LHS는 열고정 영역의 길이이다.Where L HS is the length of the cooling zone in the L C tenter and L HS is the length of the heat setting zone.
THS> (TTD+50℃) (Ⅱ)T HS > (T TD + 50 ° C) (II)
여기서, THS는 열고정 영역의 최대온도이고, TTD는 횡연신온도이다.Here, T HS is the maximum temperature of the heat setting region, and T TD is the lateral stretching temperature.
LHS< (0.5×LT) (Ⅲ)L HS <(0.5 × L T ) (III)
여기서, LHS는 열고정 영역의 길이이고, LT는 전체 텐터의 길이-횡연신 영역의 길이이다.Where L HS is the length of the heat setting region and L T is the length of the length-lateral stretching region of the entire tenter.
