经凹土胶体粒子整理的真丝织物的抗菌抗紫外性能

摘要

为了提高真丝织物的抗菌抗紫外性能,采用凹土胶体粒子对真丝织物进行整理,通过激光粒度仪、SEM、抗菌抗紫外等测试,对凹土的分散性及整理后真丝织物的结构与性能进行表征.结果表明:凹土颗粒呈纳米级棒状结构,晶束短且比较均匀,粒径为100 nm左右,粒径随着凹土质量分数的增加而增大,并且发生团聚；经凹土胶体粒子整理的真丝织物具有优良的抗菌抗紫外性能,当凹土质量分数为10％时,对大肠杆菌的抑菌率达到93.4％,UPF值达到49.9.%In order to improve the antibacterial properties and ultraviolet resistance of silk fabric, silk fabric was finished with attapulgite colloid nanoparticles. The dispersion of attapulgite, structure and properties of silk fabric before and after finish were characterized by laser particle size analyzer, SEM, antibacterial properties and ultraviolet resistance measurement. The results indicated the attapulgite particles were rod-shape with 100 nm of particle size, short and uniform crystal beam. The particle size increased with the increase of the attapuligte concentration and occurred aggregation. The finished fabric had excellent antibacterial and ultraviolet resistance properties. When the concentration of attapulgite was 10%, the inhibition rate reached 93.4% to E. coli and the UPF value was 49.9.
