Abstract
Description
生体を構成する組織には圧電性を有するものが多い。例えば、人体を構成するコラーゲンは、タンパク質の一種であり、血管、真皮、じん帯、健、骨、または軟骨等に多く含まれている。コラーゲンは、圧電体であり、コラーゲンが配向した組織は非常に大きな圧電性を示す場合がある。骨の圧電性については既に多くの報告がなされている(例えば、深田栄一,生体高分子の圧電気、高分子Vol.16(1967)No.9 p795-800等を参照)。したがって、抗菌繊維1または抗菌繊維2を備えた抗菌繊維により電場が生じ、該電場が交番するか、または該電場の強度が変化すると、生体の圧電体は、逆圧電効果によって振動を生じる。抗菌繊維1または抗菌繊維2によって生じる交番電場、あるいは電場強度の変化により、生体の一部、例えば毛細血管や真皮に微小な振動が加えられ、その部分の血流の改善を促すことができる。これにより皮膚疾患や傷等の治癒が促される可能性がある。したがって、抗菌繊維は、生体作用圧電糸として機能する。
上述したように、抗菌繊維1は、外力が係った場合に、負の電荷を生じる。抗菌繊維2は、外力が係った場合に、正の電荷を生じる。そのため、抗菌繊維1は、正の電荷を有する物質(例えば花粉等の粒子)を吸着する性質を有し、抗菌繊維2は、負の電荷を有する物質(例えば黄砂等の有害物質等)を吸着する。したがって、抗菌繊維1または抗菌繊維2を備えた布は、例えばマスク等の医療用品に適用した場合に、花粉または黄砂等の微粒子を吸着することができる。
