Preparation of eco-friendly multifunctional lyocell fabric with flame retardant, antibacterial and UV resistant using glucose-derived N-P compounds

A biomass-based finishing agent (ArCP) rich in nitrogen and phosphorus was synthesized from glucose, arginine and phosphorous acid, which was then used for lyocell fabrics to prepare flame retardant, antibacterial and UV resistant properties lyocell fabrics (ArCP-lyocell). The elemental composition, surface morphology, combustion performance, antibacterial and UV resistant properties for the lyocell fabrics before and after modification were investigated. ArCP-lyocell fabrics showed excellent self-extinguishing properties with a limiting oxygen index (LOI) of 35.1 % and maintained an LOI of 30.7 % even after 30 laundering cycles (LCs). Antibacterial experiments confirmed the antibacterial effect of ArCP-lyocell against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), with 99.9 % and 92.8 % inhibition rates, respectively. In addition, the modified fabrics exhibited excellent UV resistant properties with a UV production factor (UPF) of up to 184.54, and lower transmittance both UVA and UVB rays under 2 %. This study provides a simple and efficient approach for developing ecofriendly multifunctional textiles.
