Description

マスク用シートMask sheet
　本発明は、空気中に浮遊する花粉のマスクへの付着を防止するためのマスク用シートおよび該マスク用シートを用いるマスクに関する。 The present invention relates to a mask sheet for preventing the pollen floating in the air from adhering to the mask, and a mask using the mask sheet.
　近年、多くの人が花粉症を患っており、深刻な社会問題となっている。花粉症は、花粉が体内に入ることにより、クシャミ、鼻水、頭痛、流涙、目のかすみおよび全身倦怠感などの様々な症状を生じるアレルギー疾患である。 In recent years, many people suffer from hay fever, which is a serious social problem. Hay fever is an allergic disease that causes various symptoms such as sneezing, runny nose, headache, lacrimation, blurred vision and general malaise when pollen enters the body.
　花粉症を治療するための様々な医薬品や治療法が研究されているが、花粉を体内に侵入させないことに勝る方法はない。そこで、花粉が体内に侵入するのを防ぐために、花粉を通過させないマスクや花粉を捕捉して吸着するマスクが数多く開発されている（特許文献１～３）。 Various drugs and treatments for treating hay fever have been studied, but there is no better way to prevent pollen from entering the body. Therefore, in order to prevent pollen from entering the body, many masks that do not allow pollen to pass through and masks that capture and adsorb pollen have been developed (Patent Documents 1 to 3).
　しかしながら、例えば、外出した際に、これらのマスクを装着することで花粉が体内に侵入しなかったとしても、マスクに付着した花粉はそのまま屋内に持ち込まれ、マスクに付着した花粉が屋内で浮遊し、その花粉が体内に侵入することにより花粉症が発症又は悪化することも多い。 However, even if the pollen does not enter the body by wearing these masks when going out, for example, the pollen attached to the mask is brought indoors as it is, and the pollen attached to the mask floats indoors. In many cases, hay fever develops or worsens when the pollen enters the body.

　従来提案されたマスクでは、いずれもマスクへの花粉の付着を十分に防止することはできず、花粉の付着防止能を備えたマスクの開発が望まれている。したがって、本発明は、花粉の付着防止能に優れたマスク用シートを提供することを課題とする。 None of the conventionally proposed masks can sufficiently prevent pollen from adhering to the mask, and it is desired to develop a mask having the ability to prevent pollen from adhering. Therefore, this invention makes it a subject to provide the sheet | seat for masks excellent in the adhesion prevention capability of pollen.

At the same time, the inventors have found that they are less likely to be charged with static electricity and do not attract pollen, thereby completing the present invention.
