Polarizing-film manufacturing method |
| abstract |
PROBLEM TO BE SOLVED: To provide a method for producing a polarizing film capable of easily producing a polarizing film excellent in polarizing performance, even when a thin polyvinyl alcohol film is used, the film is not easily broken during drawing or drying. [MEANS FOR SOLVING PROBLEMS] A method for producing a polarizing film having a stretching process for stretching a polyvinyl alcohol film, comprising the steps of: spraying gas on both ends in the width direction of a polyvinyl alcohol film having water on its surface; and / Wherein the method comprises the steps of: It is preferable that the polyvinyl alcohol film having a water immersion process in which the polyvinyl alcohol film is immersed in water and the polyvinyl alcohol film having water on the surface is taken out from the polyvinyl alcohol film immersed in water by the water immersion process. |
