具有荧光和抗菌多功能纺织品的制备与性能

Preparation of multifunctional textiles with fluorescence and antibacterial properties

以萘酰亚胺为母体,设计合成一种具有双子季铵盐荧光抗菌功能的染料NA-3,并将其用于改性涤纶和棉织物的染色,获得2种具有荧光的抗菌多功能面料。研究了功能染料在水溶液中的光学性能和抗菌性能,以及在两种功能面料上的性能。结果表明,NA-3在水中有106数量级的荧光强度,浓度为40μmol/L时,对金黄葡萄球菌和大肠埃希菌的抑菌率可以达到99.99%。染色后的多功能涤纶面料上的荧光强度可以达到107数量级,对金黄葡萄球菌和大肠埃希菌的抑菌率超过70%。棉织物上的荧光强度为106数量级,对金黄葡萄球菌和大肠埃希菌的抑菌率可以达到90%。两种面料均具有良好的荧光发射和抗菌性能。

Using naphthalimide as a matrix,the fluorescent antibacterial dye NA-3 containing double quaternary ammonium salt groups is designed and synthesized.It is used in the dyeing of modified polyester and cotton fabrics to obtain multifunctional fabrics with high color visibility and healthcare.The optical and antibacterial properties of functional dyes in aqueous solution and their properties on two kinds of functional fabrics are stud⁃ied.The results show that NA-3 has a fluorescence intensity of 106 orders of magnitude in water.When the concentration of NA-3 is 40μmol/L,the antibacterial rate against Staphylococcus aureus and Escherichia coli can reach 99.99%.The fluorescent intensity of the dyed multi-functional polyester fabric can reach 107 orders of magnitude,and the antibacterial rate against Staphylococcus aureus and Escherichia coli exceeds 70%.The fluorescence intensity of cotton fabric is 106 orders of magnitude,and the antibacterial rate of Staphylococcus aureus and Escherichia coli can reach 90%.Both fabrics have good fluorescence emission and antibacterial properties.
