抗菌剂改性纤维素物料及其抗菌性能(Ⅱ)--改性纤维素物料抗菌素的释出及其抗菌性能

摘要

抗菌剂(CA)改性棉纱布(CM)和漂白棉布(CC)系经CA与CM和CC相互吸附作用而制成.本文研究了在不同pH值溶液中抗菌素释出状况.试验结果证明,在pH＝7.0时抗菌素释出量最大.改性纤维素物料的微生物试验表明其具有抗菌性能,作为重要医疗包扎物品,具有实际应用价值.%Dressing cellulose materials(CM) and bleached cotton cloth (CC) modified by surfactant antiseptics(CA) have been prepared by the method of adsorption interaction between CM and CA. Antiseptics release was studied by the method of desorption in solutions at different pH values. Maximum release of surfactants is achieved in solutions at pH=7.0. Microbiological tests of modified cellulose materials have shown that they exhibit antimicrobial activity. These results are valuable for practical application in clinics for imparting antimicrobial properties to dressing materials.
