In situ synthesis of Ag/AgX nanoparticles (NPs) onto viscose fibers adds new functionalities and broadens their applications. In this study, Ag/AgX (X = Cl, I) NPs were in situ synthesized onto viscose fibers to impart brilliant colors, UV-protection, antimicrobial, self-cleaning, and photocatalytic properties. The AgX NPs were deposited on the fibers by ultrasonic irradiation, while Ag-NPs were formed by photoreduction of excess Ag⁺ ions under UV irradiation. The Ag/AgX NPs-loaded onto viscose fibers endowed with pale yellow for Ag/AgI and pale purple/violet for Ag/AgCl. The colored viscose fibers showed excellent antimicrobial activity against Escherichia coli (gram-negative), Staphylococcus aureus (Gram positive), and Candida Albican. The Ag/AgX/viscose fiber also showed excellent photocatalytic and self-cleaning activity toward degradation of methylene blue.

在粘胶纤维上原位合成Ag / AgX纳米颗粒（NPs）可以增加新的功能并扩大其应用范围。在这项研究中，Ag / AgX（X = Cl，I）NPs在粘胶纤维上原位合成，以赋予鲜艳的色彩，防紫外线，抗菌，自清洁和光催化性能。AgX NPs通过超声辐照沉积在纤维上，而Ag-NPs是通过在紫外线辐照下对多余的Ag ⁺离子进行光还原而形成的。负载在粘胶纤维上的Ag / AgX NPs对于Ag / AgI具有淡黄色，对于Ag / AgCl具有淡紫色/紫罗兰色。有色的粘胶纤维对大肠杆菌（革兰氏阴性），金黄色葡萄球菌（革兰氏阳性）和白色念珠菌具有优异的抗菌活性。。Ag / AgX /粘胶纤维对亚甲基蓝的降解也显示出优异的光催化和自清洁活性。
