Polarizing film manufacturing method and manufacturing device |
| abstract |
An object of the present invention is to provide a method and a device for manufacturing a polarizing film that is not easily shrunk even when exposed to a high temperature environment and has excellent optical characteristics.n n n The solution of the present invention is a method for manufacturing a polarizing film, which includes a dyeing step of dyeing a polyvinyl alcohol-based resin film with a dichroic pigment, and sequentially sequencing the polyvinyl alcohol-based resin film after the dyeing step. Cross-linking step of dipping in n (n is an integer of 2 or more) cross-linking baths for cross-linking treatment, and for dipping in the x-th (x is an integer of n or less) arranged from the upstream side to the downstream side The above-mentioned polyvinyl alcohol-based resin film pulled out after the x-th cross-linking bath is subjected to an electromagnetic wave irradiation process in which the ratio of the radiant energy of infrared rays with a wavelength exceeding 2 μm and less than 4 μm is 25% or more of the total radiant energy ; Each cross-linking bath is composed of a solution having a boron compound concentration of 0.5% by mass or more, and the n-th cross-linking bath disposed at the nth cross-linking bath from the upstream side to the downstream side is composed of the aforementioned boron compound concentration of 2.4% by mass It consists of the following solutions. |
