| titleOfInvention | Method for producing polarizing film |
| abstract | The invention provides a method for manufacturing a polarizing film, which sequentially comprises the following steps: a swelling treatment step of conveying a long polyvinyl alcohol resin film having a thickness of 65 μm or less while winding the polyvinyl alcohol resin film from a raw material roll, thereby immersing the polyvinyl alcohol resin film in a swelling bath and then taking out the polyvinyl alcohol resin film; and a dyeing treatment step of immersing the film drawn out from the swelling bath in a dyeing bath and then drawing out the film, wherein a curl angle of at least one of both ends in a film width direction when the polyvinyl alcohol resin film is immersed in the swelling bath is less than 90 °. |
