| titleOfInvention | Manufacturing method of polarizer and polarizing plate manufactured therefrom |
| abstract | The present invention relates to a manufacturing method of a polarizer used in a thin film transistor liquid crystal display (TFT-LCD) for mobile, notebook computer, computer monitor and TV, and a polarizing plate manufactured therefrom, the method of manufacturing a polarizer according to the present invention A swelling step of swelling a polyvinyl alcohol (PVA) film, which is a base film of the polarizer, in a swelling tank containing a swelling liquid as a pretreatment step before a dyeing step; A dyeing step of dyeing the base film with iodine or dichroic dye; A crosslinking step of crosslinking the base film with a crosslinking agent; Drying step of drying the base film under a temperature of 40 to 60 ℃; At least one of the dyeing step and the drying step includes the stretching step of stretching the base film using a stretching roller, wherein the stretching step is the first stretching step and the second stretching in accordance with the change of the rotational speed of the stretching roller And a drawing roller, a second roller provided at a contact point between the first roller installed at the inlet of the first drawing section, the outlet of the first drawing section and the inlet of the second drawing section, and the second drawing. It consists of a third roller installed at the exit of the section, the rotational speed ratio V 1 of the first roller and the second roller is (rotational speed of the second roller) / (rotational speed of the first roller), the second roller And when the rotation speed ratio V 2 of the third roller is expressed as (rotation speed of the third roller) / (rotation speed of the second roller), the section speed ratio expressed by V 1 / V 2 is 0.5 to 2.5. It is done.n n n According to the present invention, there is an advantage that a production method for providing an optimum section ratio in a two-stage stretching step can be obtained. |
