下記表4~6に実施例17~36及び比較例9~15のそれぞれについて、処理液の詳細、抗ウイルス性及び抗菌性の評価結果をまとめた。
以上の通り、別浴処理及び同浴処理のいずれにおいても、繊維に対して窒素を含有するポリマーとアニオン界面活性剤とを接触させることで、抗ウイルス性及びその洗濯耐久性、並びに、抗菌性及びその洗濯耐久性に優れる繊維製品を製造することができた。これは、以下のメカニズムによるものと推定される。すなわち、アニオン界面活性剤が窒素を含有するポリマーとともに繊維に付着した場合、当該ポリマーが繊維に比較的強固に付着し易く、且つ、当該ポリマーの窒素部分にアニオン界面活性剤が化学的に引き寄せられ易いことから、結果として、アニオン界面活性剤の繊維からの脱落が抑制されたものと考えられる。また、窒素を含有するポリマーは繊維の表面において皮膜を形成するものが多く、この場合、皮膜による物理的な作用によっても、アニオン界面活性剤の繊維からの脱落が抑制されたものとも考えられる。
