摘要: A germicidal absorptive material for use in surgical packings, sanitary tampons and similar uses is provided by a sponge-like matrix of polyvinyl alcohol-acetal copolymer to which tightly bound disinfectant dye. Polyvinyl polymer shows exceptional avidity number dyes, both acidic basic, such as methylene blue gentian violet. Consequently, sponges this containing dye release no an aqueous solution. The generally porous that particles or fines into wounds body orifices. Presence allows the sponge inhibit bacterial growth different situations. Several common bacteria are killed being incubated presence embodiment invention contains
