| titleOfInvention | Manufacturing method of polarizing film, polarizing film and polarizing plate |
| abstract | An object of the present invention is to solve the problem of breakage and wrinkles in the entire manufacturing process of a polarizing film, and to manufacture a polarizing film with high productivity and little polarization unevenness. 1) A method of producing a polarizing film through a step of unwinding a polyvinyl alcohol film from a roll and transferring it horizontally, 2) a water swelling step, 3) a dyeing step, 4) a stretching step, and 5) a boric acid crosslinking step. And before and / or after any of the steps 2) to 4), gas is blown to both ends of the film in the width direction under the following condition a) to prevent curling of the film. A method for producing a polarizing film. Condition a) The angle θ1 formed by the gas blowing direction and the surface of the film is 5 to 80 °. |
