摘要：
A polarizing substrate is placed into a dyeing tank for dyeing. A concentration of a dyeing agent in the dyeing tank is less than 800 ppm, and a dyeing period is greater than 200 seconds, so as to improve the dyeing of the polarizing substrate by lengthening the dyeing period and reducing the dyeing agent concentration.
