Abstract: 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. Keywords: Cotton fabric, Nanocellulose, Chitosan, UV protection
development [4-7]. A lot of studies have been reported to improve the UV protection properties of cotton textiles with the methods of adjusted the textiles construction parameter, the use of coloring and/or finishing agents, and the addition of UV blockers on the surface of the cotton fabrics [8]. Among these methods, incorporating UV blockers on the fabric surface by means of coating is the most effective and simplest way to improve the UV protection properties of the textile fabrics [9]. The conventional UV blockers are organic or inorganic colorless compounds with strong absorption in the UV range of 290-360 nm. The organic UV absorbers are mainly derivatives of O-hydroxy benzo phenones, O-hydroxy phenyl hydrazines, and O-hydroxy phenyl trizaines [10]. However, the organic UV blockers has raised the environmental issues such as environmental pollution and excessive water consumption due to its toxicity. While, the most widely used inorganic UV blockers are the photo catalysts such as TiO2, ZnO and Al3O2, because of their non-toxicity and chemical stability under high temperature and prolonged UVR exposure [11]. However, the limitation of inorganic UV absorbers is the poor activity and the weak washing fastness [12]. In recent years, due to the novel properties of nanoparticles, their application in the field of textiles has increased rapidly. Many nanoparticles have been successfully used in cotton fabrics, such as TiO2 nanoparticle [13,14], Cu2O nanopartic
