Abstract
Tea polyphenols (TP) are endowed with numerous outstanding properties due to their natural structure, and their use in the preparation of multifunctional finishing agents is a novel topic. In this paper, a multifunctional finishing agent, PAT, was prepared by using phytic acid and TP as raw materials and finished on the surface of viscose fabrics to obtain PAT-100. After measurement, the limiting oxygen index of PAT-100 achieved 32.9 %, and the peak heat release rate was reduced by 90 %. Due to the presence of polyphenolic groups, PAT exhibited excellent inhibitory effects on Staphylococcus aureus and Escherichia coli, and the UPF value was improved to 53.2. Furthermore, this system also improved the hydrophobicity of viscose fabrics, and the breaking force retention in the warp and weft directions reached 130 % and 156 %, respectively. This work presents new ideas for TP in the field of multifunctional finishing and increases the added value of viscose fabrics.
