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 pho
