The functional fabrics of Nano-ZnO in situ and anti-ultraviolet function

摘要

In use of the sodium hydroxide solution and zinc chloride solution, Nano-ZnO particles were generated in-situ on the cotton samples. Nano-ZnO is six-party crystal, the crystallization is integrity and high purity; Nano-ZnO particles and cotton fiber has a good combination of fastness, washes 8 times in the standard condition, the gain rate remains constant, it is 7.81%; the size of Nano-ZnO is 6.2 ~ 15.8nm after washes 8 times in the standard conditions. The UVA and UVB ultraviolet transmittance of samples are 6.4%and 4.4%, which are compared with the original cloth samples; they respectively decrease by 67.7%, 62.1%. UPF is 16.3, according to AS /NZS 4399 UPF fabric assessed, it get the better level.
