Abstract

PURPOSE:To provide extended film of smooth surface by apply two-exis extension on it applying stream on the surface of film, and while the temperature of the film is in a specified range, after the film is formed by extruding line-shaped molten poliamide. CONSTITUTION:Film, 50-300mu thick, is made by extruding line-shaped molten polyamide. After this, while the temperature of the film remains in the range of 140-190 deg.C, steam is applied on the surface of the film under the condition that the water content of the film does not exceed 1weight%. Then two-axis extension is performed on successively on it. EFFECT:Smoothness is improved by causing unevenness of the film surface resulting from the extension, since drops of water attached on the film surface make concave spots and cause crystalizing of the only attached portions.
