Colored wool fabric with special functions, including self-cleaning, anti-bacterial, and ultraviolet (UV) blocking, has been prepared by applying nano ZnO as a photocatalyst and henna as both a natural dye for coloration and an agent capable of modifying the ZnO nanoparticles. Natural dye henna has been used as photo sensitizer to fabricate zinc oxide nanoparticles. Coloration of wool fabrics and surface modification of fabric are performed by adding modified zinc oxide nanoparticles in exhaustion bath. The self-cleaning property of treated wool fabrics is evaluated through discoloring methylene blue dye under sunlight irradiation. The antibacterial activities of the samples against two common pathogenic bacteria, namely Escherichia coli and Staphylococcus aureus have also been assessed. The results indicate that adding natural dye henna to zinc oxide leads to better self-cleaning properties, even the photocatalytic activity of ZnO has no negative effect on fabric color. Moreover, this process imparts proper antibacterial properties and UV-blocking activity to wool fabrics.

在天然染料指甲花存在下使用纳米氧化锌生产多功能羊毛织物

通过使用纳米ZnO作为光催化剂和指甲花作为天然着色剂和能修饰ZnO的试剂，已制备出具有特殊功能的有色羊毛织物，包括自洁，抗菌和紫外线（UV）阻隔。纳米粒子。天然染料指甲花已被用作光敏剂以制造氧化锌纳米颗粒。羊毛织物的着色和织物的表面改性是通过在排气浴中添加改性的氧化锌纳米颗粒来进行的。通过在阳光照射下使亚甲基蓝染料褪色来评估处理过的羊毛织物的自洁性能。样品对两种常见的致病菌，即大肠杆菌和金黄色葡萄球菌的抗菌活性。也得到了评估。结果表明，向氧化锌中添加天然染料指甲花会导致更好的自洁性能，即使ZnO的光催化活性也不会对织物颜色产生负面影响。而且，该方法赋予羊毛织物适当的抗菌性能和紫外线阻断活性。
