| titleOfInvention | Stretched film manufacturing method and polarizing film manufacturing method |
| abstract | Provided is a method for producing a stretched film made of a polyvinyl alcohol-based resin capable of realizing a high draw ratio in TD (film width direction) and having excellent axial orientation in TD, and a method for producing a polarizing film exhibiting good optical performance using the same do. A stretching step of obtaining a stretched film by stretching the polyvinyl alcohol-based resin film, wherein the stretching step is performed by transversely stretching the polyvinyl alcohol-based resin film at a MD shrinkage ratio of the polyvinyl alcohol-based resin film in comparison at the same TD stretching ratio. A first stretching treatment step of simultaneously performing TD stretching and MD shrinkage so that the MD shrinkage ratio is larger than the MD shrinkage ratio in the case of performing, and a second stretching treatment step of simultaneously performing TD stretching and MD shrinkage so that the MD shrinkage ratio is lowered by 0.17 or more. It is the manufacturing method of the stretched film included in this order, and the manufacturing method of the polarizing film using the obtained stretched film. |
