Ear material for mask, mask manufacturing method for mask, mask material for mask, and manufacturing method of mask

摘要

Problem to be solved: to provide an elasticized mask ear material capable of maintaining the original characteristic by deformation during mounting.Solution: a stretchable member having a first surface and a second surface opposite to the first surface, a first surface material bonded to the first surface, and a second surface material bonded to the second surface, and the stretchable member has a natural length before the start of use, and The first surface material and the second surface material are contracted in the predetermined direction, the mask material for the mask.Diagram
