聚磺酸甜菜碱的合成及在棉织物抗菌整理中应用
|
摘要
为实现棉织物的高效持久抗菌功能,制备了一种聚磺酸甜菜碱(PSPB)抗菌整理剂并将其应用于棉织物的抗菌整理。通过单因素分析法,探讨了PSPB质量浓度、浴比、浸泡时间、烘焙温度与烘焙时间对棉织物抑菌圈大小的影响,得到抗菌整理的优化工艺;采用活菌计数法对经优化工艺整理的棉织物进行抗菌性能及耐洗牢度测试。结果表明,抗菌整理的优化工艺条件为:PSPB质量浓度54 g/L,浴比1∶30,浸泡时间50 min,烘焙温度170℃,烘焙时间150 s。红外光谱与扫描电镜表征证实PSPB成功合成且成功接枝到棉纤维表面。整理后织物对大肠杆菌与金黄色葡萄球菌的抑菌率分别为99. 87%、99. 99%,且具有优异的耐洗性能。织物断裂强力及白度测试结果表明,PSPB抗菌棉织物的强力与白度均满足服用要求。
In order to realize the efficient and durable antibacterial activities of cotton textiles,polysulfopropylbetaine( PSPB) antibacterial agents were prepared and applied in the functional finishing of cotton fabrics. The influence of finishing agent concentration,bath ratio,soaking time,baking time and baking temperature on the inhibition zone of cotton fabrics were carried out. The optimal conditions are 54 g/L of finishing agent concentration,1 ∶30 of bath ratio,50 min of soaking time,150 s of baking time and 170 ℃ of baking temperature. Additionally,counting viable bacteria method was adopted to test the antibacterial properties and fastness to washing of cotton fabrics finished under the optimum reaction conditions. Also,it was proved that PSPB is synthesized and grafted successfully onto the surface of cellulose by characterization of infrared spectrometer and scanning electro microscopy. It is shown that the cotton fabrics finished by PSPB possesses excellent washability,and exhibits good antibacterial activity against both gram-negative bacteria Escherichia coli and gram-positive bacteria Staphylococcus aureus,with 99. 87% and 99. 99%,respectively,in antibacterial ratio. In terms of tests on the breaking strength and whiteness,no significant influence exists on cotton fabrics finished with PSPB and both properties accord with wearing needs.
