A Biocompatible and Sustainable Anti-ultraviolet Functionalization of Cotton Fabric with Nanocellulose and Chitosan Nanocomposites

摘要

For improving the ultraviolet (UV) protection property of cotton fabric and exploiting ecological cotton textiles, cotton fabric was modified with a kind of biocompatible and nontoxic of chitosan (CS)/nanocellulose (NCs) nanocomposites using a pad-dry-cure process. The effect of particle size of NCs on the morphology and property of CS/NCs cotton fabrics were carefully investigated by SEM, FTIR, and mechanical property, water wettability, UV protection and laundering durability analysis. The results revealed that the CS/NCs coated fabrics performed excellent UV protection ability as well as a good laundering durability. The UPF values of all the CS/NCs coated fabrics were much higher than that of untreated fabric even after 30 cycles of laundering. Moreover, the particle size of NCs had a negative effect on the UV protection ability of CS/NCs coated fabric. Meanwhile, coated with CS/NCs nanocomposites was benefit to enhance the mechanical property, and hydrophobicity of cotton fabric.
