Abstract
Provided is a method of cleaning a flexible substrate. The method includes the steps of: preparing a flexible substrate and detaching an impurity adhered to both surfaces of the flexible substrate using rotating first rollers disposed on the both surfaces of the flexible substrate; and removing the impurity by transferring the impurity from the first roller to a second roller using the rotating second roller having a relatively higher adhesion than the first roller.
Claims6
A method of cleaning a flexible substrate, comprising the steps of:
- preparing a flexible substrate and detaching an impurity adhered to both surfaces of the flexible substrate using a plurality of rotating first rollers disposed on the both surfaces of the flexible substrate;
- and
- removing the impurity by transferring the impurity from a pair of the plurality of rotating first rollers to a rotating second roller using the rotating second roller having a higher adhesion strength than the plurality of rotating first rollers, and
- wherein the higher adhesion strength of the second roller is 0.3 to 100N/100mm stronger than an adhesion strength of each of the pair of the plurality of rotating first rollers.
