Problems solved by technology

In this three-dimensional mask, in order to eliminate the wearer's difficulty in breathing and obtain the desired barrier performance against viruses such as colds, focusing on the air permeability of the mask and the capture property of the mask, by using electretized electret body fiber sheet, improve the air permeability of the mouth mask and the collection of the mouth mask, but when designing this three-dimensional mask that adopts the electret fiber sheet, in order to make the air permeability of the opposite mouth mask and the collection of the mouth mask mutually High level of compatibility with room for further improvement

Abstract

Provided is an effective technology which establishes high levels of both mask ventilation and mask collection characteristics for a mask fitted on the face of the wearer. A mask (1) is comprised of a mask body (10) which covers at least the mouth and the nose of the wearer, and a pair of ear fasteners (20) which extend out of both sides of the mask body (10) and catch onto the ears of the wearer. The mask body (10) includes a first fiber sheet and a second fiber sheet which are electret nonwoven sheets composed of a polypropylene fiber. The first fiber sheet is formed as a nonwoven sheet having an average fiber diameter of 0.5 to 3 mm and an areal weight of 1.5 to 5 g/m2. The second fiber sheet is formed as a nonwoven sheet with both an average fiber diameter and an areal weight greater than those of the first fiber sheet.

Description

technical field [0001] The present invention relates to the construction technique of the mask worn on the wearer's face. Background technique [0002] In Japanese Patent Laying-Open No. 2007-37737, a mask covering the wearer's mouth and nose is disclosed, especially a three-dimensional mask. In this three-dimensional mask, in order to eliminate the wearer's difficulty in breathing and obtain the desired barrier performance against viruses such as colds, focusing on the air permeability of the mask and the capture property of the mask, by using electretized electret body fiber sheet, improve the air permeability of the mouth mask and the collection of the mouth mask, but when designing this three-dimensional mask that adopts the electret fiber sheet, in order to make the air permeability of the opposite mouth mask and the collection of the mouth mask mutually Compatible at a high level, there is room for further improvement. Contents of the invention [0003] Therefore, ...
