| titleOfInvention | a mask |
| abstract | The invention provides a mask, comprising: preparing a dip-dyeing solution and a base material for manufacturing the mask, the dip-dye solution containing photochromic dyes and resin; driving the base material to move with a roll-to-roll device, and by having the dip-dye solution The dip-dyeing tank makes the base material absorb the dip-dye solution to form an anti-ultraviolet material on the base material, and the base material is irradiated with ultraviolet rays to convert the color. The present invention also provides a mask, comprising: an inner layer; a middle layer arranged on the inner layer; and an outer layer manufactured by the above method, the outer layer is arranged on the middle layer. The mask manufactured by the method of the present invention contains an anti-ultraviolet function. |
