Preparation of Efficient and Green Silver-Loaded Viscose Fabric and its Antibacterial Durability

Viscose fabric is susceptible to mold erosion and nourish bacteria, which limit its application. In this study, the efficient and green silver-loaded viscose fabric was prepared by simple liquid phase spray deposition method. The microstructure, physical properties, antibacterial durability of silver-loaded viscose fabric were further evaluated. The result showed that the silver-loaded viscose fabric not only kept their superior comfortability but also had an air permeability that was more than three times higher than the bare viscose fabric. In addition, the silver-loaded viscose fabric showed good antibacterial activity and the antibacterial rate reach to 99.9%. Meanwhile, the silver-loaded viscose fabric still maintained good antibacterial activity after friction treatment. The washing and chemical resistance of the silver-loaded viscose fabric could be further improved through chemical crosslinking with glutaraldehyde. This work provided a feasible way to manufacture green and durable antibacterial viscose fabric, which also improves the application potential of viscose fabric during current respiratory disease pandemic.

Automated 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.
