Application of Ag-doped nano-TiO_2 prepared at low-temperature to multi-functional finishing of cotton fabric

摘要

Ag-doped nano-TiO_2 sol was prepared at a low temperature and was used to finishing cotton fabrics, and observed the crystal structure and the dispersion of nano-TiO_2 on the fabric by X-ray diffraction (XRD) and scanning electron microscope (SEM); Discussed the influence of different amount of silver on antibacterial properties; Studied the impact of different finishing methods on UV resistance performance as well as the degradation of methylene blue and VOC performance. Results showed that Ag-doped nano-TiO_2 on the fabric which was finished by steaming method with the sol agent were anatase phase,and its particle size was 20-40 nm, when the molar ratio of tetrabutyl titanate and silver nitrate was 70:1, the Bacteriostatic rate was 99.9%, and fastness to washing was well, UV resistance and degradation of MB and VOC performance had greatly ascended, and less influence on the fabric performance.
