Abstract

Since a mask which is not suitable for a human face type has a low protection effect, it is necessary to design the shape of the mask reflecting the face shape of the human body in consideration of the size and shape of each part of the face. The masks analyzed in this study are classified into a yellow dust mask(sanitation mask) and a Fine dust protective mask sold in four countries of Korea, China, the US and England. The standard of Korea is KF(Korea Filter, particle blocking function), which is divided into KF80, KF94 and KF99, which are certified by Ministry of Food and Drug Safety. The standard of the US is N95 that is certified by the National Institute for Occupational Safety and Health (NIOSH). The result ofanalyzing the sizes of products is as follows. First, there was a significant difference among the products in the 3 horizontal length items of Nose-Tragion A, Lip-Tragion A, Menton-Tragion B and the 1 vertical length item of chin-menton length. The Nose-Tragion A was the U.S. 12.2cm > England 10.8cm > China 10.7cm > Korea 9.6cm. The result of analyzing fine dust masks in the market showed that they mark the structures, forms and penetration ratio of fine dust, but there is no size standard for each size. Therefore, it is necessary to establish standards of each size for suitable pattern designs for face shapes in each country.
