In the chemical formulas, R' indicates alkyl group of hydrogen and carbon number of 1-4 and other aryl groups.

Abstract: PURPOSE: A foldable mask and a manufacturing method thereof are provided to offer the excellent texture and dustproof effect to users, and to enable users to easily breathe when wearing the mask. CONSTITUTION: A foldable mask comprises the following: a main body(1) including holes on the left and right ends and the center for inserting fixing strings; an upper shield(2) including an upper surface layer and an upper inner layer formed with nonwoven fabric laminates; a lower shield(3) including a lower surface layer and a lower inner layer formed with the nonwoven fabric laminates; upper and lower folding units formed from the upper and lower sides of the main body; a fixing string adjuster located inside the mask, and a fixing string adjuster cover attached to the main body; and a nose-shape adjustor(4) fixed to the outer center of the upper surface layer.
