| titleOfInvention | Manufacturing method of polarizer, polarizer, polarizing plate, optical film, image display device and cleaning device |
| abstract | (assignment) Provided is a method for producing a polarizer having good optical properties from a polyvinyl alcohol-based film without causing a problem of film bending. (Solution) In the manufacturing method of light polarizer which performs a dyeing process, an extending process, and a crosslinking process at least to a polyvinyl alcohol-type film, a polyvinyl alcohol-type film has a disk width of 2300 mm or more, and wash | cleans before a dyeing process (1) In the washing step (1), the film conveyed from the first pinch roll is led through the at least first and second guide rolls, immersed in the washing bath, and guided to the second pinch rolls to form the first film. By using the circumferential speed difference between the pinch roll and the second pinch roll, washing is performed while stretching in the range of 1.2 to 2.9 times, and the first guide roll and the second guide roll are both provided in the washing bath, The pass line length a of the film between the first guide roll and the second guide roll is adjusted to 50 cm or more, and at least the second guide roll uses an expander roll having a surface length of 2300 mm or more. Manufacturing method of polarizer to make . |
