| titleOfInvention | Manufacturing method of polarizer |
| abstract | An object of this invention is to provide the manufacturing method of the light polarizer which has few scratches, wrinkles, and streaks, and is excellent in the appearance without an incision. As a solution to the above, the present invention is a manufacturing method of light polarizer which gives at least a swelling treatment, a dyeing treatment and a crosslinking treatment to a polyvinyl alcohol-based film, At the time of at least one said process, extending | stretching is carried out using at least one width expansion roll as a guide roll in a process bath, and the position which a polyvinyl alcohol-type film spaces apart from a width expansion roll satisfies following formula (1) It is characterized by arranging the widening roll so that. -40 ° ≤θ≤40 ° (1) (In formula, (theta) connects the exit point contact of the polyvinyl alcohol-type film which contact | connects the width expansion roll and the center point of the width expansion roll in the position where the arc height in the axial direction of a width expansion roll becomes maximum. It is the intersection angle of one straight line A, the point where the arc height of the width expansion roll reaches the maximum, and the straight line B which connected the center point of the width expansion roll, but a crossing angle is based on the straight line B to the advancing direction of the said film. In the case of the forward direction, let +, and in the case of reverse,-. |
