Summary: This study investigates the use of 3-chloro-2-hydroxypropyl trimethyl ammonium chloride as a cationizing agent for the modification of viscose rayon fabric to enable dyeing with acid dyes without the need for electrolytes. The results show that the modified fabric offers improved color yield and enhanced fastness properties. This research is innovative as it demonstrates the ability to dye cellulose fibers like viscose with acid dyes, which are typically used for polyamide fibers.

Summary: Efficient and green silver-loaded viscose fabric was prepared using a simple liquid phase spray deposition method. The silver-loaded fabric showed superior comfortability and over three times higher air permeability compared to bare viscose fabric. It also exhibited excellent antibacterial activity with a rate of 99.9%, and maintained this activity even after friction treatment. By using glutaraldehyde for chemical crosslinking, the washing and chemical resistance of the fabric could be further improved. This study provides a feasible way to manufacture environmentally friendly and durable antibacterial viscose fabric, enhancing its potential application during respiratory disease pandemics.

Summary: The demand for medical textiles with strong antimicrobial activity has increased during the COVID19 pandemic. In order to develop antimicrobial textiles in an environmentally friendly way, viscose fabric was coated with chitosan and impregnated with Ag- and Cu-based nanoparticles. The nanoparticles were synthesized using pomegranate peel extract as a reducing and stabilizing agent. The impregnated fabrics showed excellent antifungal and antibacterial activity, with the antibacterial activity being stronger against Gram-negative bacteria and influenced by the metal content. The fabrics impregnated with AgCl nanoparticles also exhibited lower cytotoxicity towards human keratinocyte cells.

Summary: Nanosized Ag and CeO2 particles were physically mixed to obtain composite antibacterial agents. Comparative experiments showed that the nanocomposites exhibited improved antibacterial activity and a synergistic effect between Ag and CeO2 was observed. The presence of CeO2 suppressed the release rate of silver ions and provided the composite with antibrowning ability, while the interaction between nanosized Ag and nanosized CeO2 generated more hydroxyl radicals (•OH). Hydroxyl radicals played an important role in causing bacterial death for the Ag-CeO2 composite antibacterial agent.
