以下の装置・条件で測定し、含有元素の定性・半定量を行った。
装置;理学電気(株)製 全自動蛍光X線分析装置、RIX−3000
管球;Rh管球 測定径;25mmφ
装置;ヤナコ製 MT−700CN
無機元素含有量=無機元素測定値×(100−CHN含有量)/100
すなわち、有機物由来と考えられるCHNの含有量(約70%)を全量から除き、その残りの(約30%)を無機元素含有量で割り振った。ただし、本測定では、必ず含まれている0(酸素)の含有量を把握できないため、無機元素の含有量には“<”を付した。Tiの形態をTiO2と仮定すると、含まれるTiとOとの重量比は100:67となり、上表の推算値は次表のように換算される。
1.綿タオル1kgを30分間本発明の光触媒脱臭殺菌方法を利用した装置に投入し、100℃で熱風を送風して乾燥し試料タオルを得た。また、前記処理した試料タオルの一部は洗剤(花王石鹸(株)製 ハイトップ)を使用して、10分間洗濯した後、水道水で5分間水洗いすることを50回繰り返し、最後に100℃で乾燥して他の試料タオルを得た。
2.前記綿タオルの代わりに、1kgのポリエステル繊維布を使用した。それ以外は上記と同様の操作を行った。
3.抗菌試験大腸菌と黄色葡萄状球菌をリン酸バッファーに懸濁させ、200mlの三角フラスコにこの溶液75mlと上記本発明で使用する透明液状光触媒0.75gを入れ、25℃±5℃に保持して、回転数330rpmで1時間振動処理した。この処理液の生菌数を測定して下記滅菌率を算出した。
Claims (4)
- 密閉室内の衣服等の繊維物質に液状光触媒を噴出する光触媒噴出手段と、前記繊維物質に付着する光触媒に紫外線を照射する紫外線照射手段と、前記繊維物質に付着する液状光触媒に熱風を送風して乾燥させる熱風乾燥手段とからなり、前記光触媒噴出手段において光触媒が繊維状酸化チタン超微粒子であり、該繊維状酸化チタン超微粒子を適量分散させた透明液状光触媒を噴出するようにし、前記熱風乾燥手段における熱風の温度を30〜120℃とし、密閉室内に充満する繊維状酸化チタン超微粒子を熱風により前記繊維物質の繊維全体へ均一に固着乾燥させるようにした光触媒脱臭殺菌方法。
- 前記光触媒噴出手段における液状光触媒中の無機元素が半定量値において、少なくともTiが90〜97wt%、Siが2.3〜3.0wt%、Agが1.4〜2.2wt%、Znが0.2〜0.3wt%含む請求項1記載の光触 媒脱臭殺菌方法。
- 前記光触媒噴出手段における液状光触媒中の有機元素が定量値において、少なくともCが55〜65wt%、Hが8〜12wt%、Nが0.2〜0.4wt%含む請求項1又は2記載の光触媒脱臭殺菌方法。
- 前記液状光触媒中における酸化チタンが繊維状の超微粒子であり、平均繊維幅及び厚さが1〜50nm、平均繊維長さが10〜1000nm、平均アスペクト比が2〜100、比表面積が30m2/g以上である請求項1乃至3の何れかに記載の光触媒脱臭殺菌方法。
