The lowering intake of organic dyes and their auxiliaries by employing nanoparticles for some special textile coloration is novel and interesting topic. Nonetheless, application of reducing, stabilizing and other chemical agents in textile nano-coloration is still undesirable from both environmental and human/aquatic life viewpoints. This research renders a facile technique for wool coloration through locally forming selenium nanoparticles using sodium selenite without using other chemicals. Being industrially enforceable, free from use of additional chemicals, showing photo-active ability to discolor the dyeing effluent and low-toxic colorant are the main privileges of the used method. The wool fabrics were colored light to dark orange depending on coloration time and concentration of sodium selenite. Also, the color fastness properties against washing, rubbing and acid/alkaline spotting of prepared samples were excellent. Moreover, the colored fabrics indicated reasonable bactericidal and fungicidal performances toward Escherichia coli, Staphylococcus aureus and Candida albicans (95, 70 and 100 %, respectively) and still remained compatible with human skin. The in-situ synthesis of selenium nanoparticles on wool fabric not only colored the wool but also promoted the UV-protecting performance by 61.82 %, photocatalytic activity through methylene blue discoloration under sunlight by 97.22 % and tensile strength by 11.27 %.

通过将纳米粒子用于一些特殊的纺织品着色来降低有机染料及其助剂的摄入量是一个新颖而有趣的话题。尽管如此，从环境和人类/水生生物的角度来看，在纺织品纳米着色中应用还原剂、稳定剂和其他化学剂仍然是不可取的。这项研究通过使用亚硒酸钠在不使用其他化学品的情况下局部形成硒纳米粒子，提供了一种简便的羊毛着色技术。在工业上可执行、不使用额外的化学品、显示出使染色流出物变色的光活性能力和低毒着色剂是所用方法的主要优势。羊毛织物根据染色时间和亚硒酸钠浓度从浅橙色到深橙色。还，制备的样品的耐洗、耐摩擦和耐酸碱斑点色牢度性能优异。此外，有色织物显示出合理的杀菌和杀菌性能，对大肠杆菌、金黄色葡萄球菌和白色念珠菌（分别为 95%、70% 和 100%）仍然与人体皮肤相容。在原位上羊毛织物合成硒纳米粒子不仅着色的羊毛，而是由61.82％，光催化活性通过在太阳光下亚甲基蓝脱色也促进了UV保护性能由97.22％和拉伸强度由11.27％。
