摘要：以植物还原剂——金银花提取物和化学还原剂——丙三醇，分别还原硝酸银，制备了两种纳米银溶液。
采用浸渍法将上述制备的纳米银溶液分别对棉织物进行功能整理。利用 SEM、EDS、XRD、FTIR 分析整

Abstract: Two kinds of nano-silver solutions were prepared by reducing silver nitrate with plant reducing
agent (honeysuckle extract) and chemical reducing agent (glycerol), respectively. The samples were then
used for functional finishing of cotton fabrics by dipping method. The morphology and structure of cotton
fabrics before and after finishing were analyzed by SEM, EDS, XRD and FTIR. The anti-ultraviolet
performance of silver-loaded cotton fabrics and the changes of silver content, color difference and
antibacterial property after different washing times were discussed. The results showed that nano-silver
particles were mainly adsorbed on the amorphous region of cotton fibric cellulose by Van der Waals force.
Compared with that of the chemical reduction method, the particle size of nano-silver particles prepared by
the plant reduction method was decreased by about 15 nm. The cotton fabric finished by nano-silver
solution prepared by the plant reduction method had excellent antibacterial properties and good washing
resistance. After 50 times of washing, the adsorption amount and color difference of nano-silver on the
surface of the cotton fabric did not change much, and the antibacterial rate against E. coli and S. aureus still
reached more than 99%. In addition, the cotton fabric finished by nano-silver solution prepared by the plant
reduction method had good UV resistance with a ultraviolet protection factor (UPF) of 36.82.
