Journal Article 2022 10 10 Over the last two decades, the use of nanoparticles as textile substrates has been the subject of extensive research, aimed at producing finished fabrics with multi-functional performance. The novelty of this article is application of β-cyclodextrin (β-CD) to control the release of zinc oxide nanoparticles (NZnO) on the fabric surface, and therefore it increases the stability and effectiveness time of this substance on the fabric surface. The materials used to treat the silk fabrics were citric acid (CA) as an eco-friendly cross-linking agent and NZnO as a catalyst. In addition, the grafting of β-CD onto the silk fabrics occurred through a pad-dry-cure process. In the other hand, stability of NZnO on the fabric surface investigated by photocatalytic activity before and after of washing. These nanoparticles along with CA were found to be effective in enhancing the crease recovery performance of the silk fabric in wet (233°) and dry states (310°). As the SEM images suggested, the treated ﬁbers had CA, as a cross-linking agent, NZnO deposited on their surface. The results indicated that the as-prepared silk fabric exhibits self-cleaning performance (∆E>10) and excellent antibacterial activity (>99 % for both E. coli and S. areus).
