Abstract:

Nonwovens loaded with nano-ZnO was prepared with nano-ZnO finishing agent. Zeta particle size and potential analyzer was used to examine the Zeta potential, nano-ZnO particle size and distribution of the finishing agent. Atomic force microscopy (AFM) was employed to study the distribution of nano-ZnO on nonwovens. The results revealed that the average particle size of nano-ZnO finishing agent was less than 100 nm, and most of the particle sizes on nonwovens after treatment were less than 100 nm. The nonwoven materials loaded with nano-ZnO had good photocatalytic performance and washability. The photocatalytic reactivity still maintained above 50% after 8 times washing. Under the same experimental conditions, the nonwoven materials treated with nano-ZnO finishing agent containing acrylate adhesive had better washing fastness.
