術マスク用不織布が開示されている。Conventionally, regarding a non-woven fabric for a surgical mask composed of three layers,
Japanese Unexamined Patent Publication (Kokai) No. 52-59991 discloses a nonwoven fabric for surgical masks, which is formed by sandwiching a glass fiber sheet having a micron diameter with another fiber web.

に吸入して人体に悪影響を及ぼす怖れもある。Since this non-woven fabric uses glass fibers and other webs are made of short fibers such as rayon fibers or polyester fibers, the end of glass fibers or other short fibers is worn on the human skin when worn. There is a problem of irritating and giving a slight discomfort. In addition, there is a fear that a small piece of glass fiber may be inhaled during breathing, which may adversely affect the human body.

に、人の皮ふを刺激するという問題がある。Further, Japanese Utility Model Laid-Open No. 58-105350 discloses a sanitary mask using a spunlace woven fabric composed of two layers, one surface of which is made of plant fiber and the other surface of which is made of polyester fiber. This hygiene mask also has a problem of stimulating human skin because the constituent fibers are short fibers.

ある。顔面の凹凸によく適合するものが望まれる。The characteristics required of surgical masks are, first of all, bacterial barrier properties. The size of bacteria is 0.15-3 μm in diameter
It is said that the filter material has a dense structure that captures these minute bacteria. Although the above-mentioned glass fiber sheet has the highest characteristic, the air permeability is inferior when the structure is too dense.
Secondly, it is breathable. Since the surgical mask covers the nose, mouth, and face of a person, it is desirable that the surgical mask has good breathability so that sufficient breathing can be performed. Thirdly, it is hygroscopic. What absorbs the moisture accompanying breathing is desired. Fourth is flexibility. It is desired that it conforms well to the unevenness of the face.
