25×35cmの布帛サンプルを準備した。
細菌由来セルロース産生菌の1200ml培養物を、綿で覆ったフラスコ中で、200rpm、28℃で、2日間インキュベートした。
形成された細菌由来セルロース繊維を除去するために、スクリムを用いて培養物を濾過した。
濾過した培養物を布帛サンプルに注ぎ込み、または吹付けし、18時間インキュベートして、細菌由来セルロース層を備えた布帛サンプルを得た。
細菌由来セルロースを備えた布帛サンプルを80℃で20分間、0.1MのNaOHで洗浄し、次に蒸留水で中和した。
細菌由来セルロースを備えた布帛サンプルを、10〜40重量%のシリコーン(SANSIL MIC 3145、マイクロシリコーン)を含む混合物中(サンプル10gに対して混合物200g)で、36℃、100rpmで18時間インキュベートした。
細菌由来セルロース層とマイクロシリコーン柔軟剤とを含む複合布帛のサンプルが得られた。
サンプルを乾燥させた。
