Description
また、本発明のフィルターは上記目的を達成するために、請求項1に記載の不織布を備えたフィルターとしたものである。
これによりSARSウイルスを確実に不活化することができ、活性力を持ったまま再飛散を防止することができるフィルターが得られる。
緑茶あるいは紅茶成分から分離精製したカテキン類等と吸湿剤を、純水に溶かし調整液とし、この調整液を集塵性能を有したフィルターに噴霧処理し、脱水後乾燥処理を行い、SARSウイルス不活化フィルターを製造する。調整液はカテキン類等を0.1〜10%、吸湿剤である茶抽出のカフェインを0.01〜10%程度の濃度に調整される。SARSウイルス不活化不織布、熱交素子もフィルターと同様に、上記調整液で噴霧し、脱水後乾燥処理を行い、製造する。カテキン類等の担持量が約0.5〜3g/m2、カフェイン担持量が約0.05〜3g/m2のフィルターが得られる。本実施例では調整液を噴霧担持処理したが、調整液を浸漬、含浸担持処理しても良いし、調整液を印刷担持処理しても良い。

6.予備試験:供試フィルターのVERO E6に対する毒性作用−無毒を確認
7.試験回数:3回平均
8.試験結果(SARS−COV−P4、SARS−COV−P11とも)
1)供試フィルターと100TCID50/mlSARSウイルス希釈液5mlと室
温で6時間作用−不活化率100%
2)供試フィルターと100TCID50/mlSARSウイルス希釈液5mlと室
温で4時間作用−不活化率50%
3)供試フィルターと100TCID50/mlSARSウイルス希釈液5mlと室
温で2時間作用−不活化率25%
4)対照フィルター:不活化0%
*対照フィルター:SARSウイルス不活化剤と吸湿剤が無担持のフィルター
上記結果により、SARSウイルスを不活化するようにしたフィルターでは、不活化率100%と十分な不活化効果が得られている。
