| titleOfInvention | Method for producing polarizing film |
| abstract | A method for producing a polarizing film, comprising a stretching step of conveying a polyvinyl alcohol resin film while immersing the film in a treatment bath and uniaxially stretching the film by a circumferential speed difference between an upstream roll and a downstream roll, wherein the stretching step comprises a low width reduction rate stretching step in which a width reduction rate R is 0.55 (%/sec or less; when the width of the polyvinyl alcohol-based resin film passing through the upstream roll is W1(mm), the width of the polyvinyl alcohol-based resin film passing through the downstream roll is W2(mm), and the time required for the polyvinyl alcohol-based resin film to be conveyed from the upstream roll to the downstream roll is T (seconds), the width reduction rate R is calculated by the following formula (1): formula (1): |
