Further, Patent Document 2 discloses that a base fabric made of a fiber material is impregnated with an aqueous solution containing a positively sterilized disinfecting component, an amino acid, and a nonionic surfactant. Disinfectant that can effectively prevent sterilization and exhibit a sterilization effect is disclosed.
