Experimental research of influence of power ultrasonic on fine particles embedded into the porous textile materials

A study is made of influences of fine particles' size, ultrasonic frequency and addition agent on percentage (W) of ZnO particles embedded into the porous textile materials with power ultrasonic. To investigate these influences, five groups of ultrasonic frequencies from 28 kH to 59kH and three types of ZnO particles with different sizes are used to conduct experiments. In addition, the effects of addition agents on ZnO particles of 40 nm are compared. The results show that at lower frequency (here at 28 kHz), the value of W rises with the increase of the sizes of ZnO and in contrast at frequency of 4OkH, the value drops at the same condition. Surface-active agent such as penetrating agent and softening agent will influence the value of W more apparently than dispersing agent, which reaches up to over 0.2 per cent.
