Abstract

본 발명은 폴리-δ-카프로락탐에 폴리메타-크실렌아디프아미드 2중량% 이상 5중량% 미만 혼합하여 용융, 압출한 후 냉각하고 종방향의 연신은 50~70℃ 온도에서 2.5~3.5배로 하고 횡방향의 연신은 65~80℃ 이하의 온도에서 2.5~3.5배로 연신한 후 2% 이상 5% 이하의 이완율로 180~230℃의 온도에서 열처리하여 기계적 물성이 우수하고 열수수축율이 낮은 이축연신 폴리아미드 필름을 제조하는 방법에 관한 것이다.The present invention is mixed with poly- δ-caprolactam in a mixture of 2% by weight or more and less than 5% by weight of polymeth-xyleneadipamide to melt, extrude and cool. Stretching in the transverse direction is stretched 2.5-3.5 times at the temperature below 65 ~ 80 ℃, and heat treated at 180 ~ 230 ℃ with relaxation rate of 2% or more and 5% or less, so that biaxial stretching with excellent mechanical properties and low heat shrinkage A method for producing a polyamide film.
