Investigations on the embedding enhancement of nano-particles into wool fabric with ultrasonic
Ultrasonic is often used for laundering. However, it is proved by both experiments and theoretical analyses that ultrasonic can also push particulates into fabric under certain conditions. In this paper, wool fabric was simulated by porous filtration membrane with the aperture of 0. 15μm. The membranes were placed on the set with three different distances from ultrasonic transducer, affected by five different hydraulic pressure grads and ultrasonic fields with frequency of 28kHz and 40kHz, respectively. Measuring the penetrability and comparing the data with that measured without the effect of ultrasonic. It was proved that the penetrability of porous material can be enhanced by ultrasonic, and the enhancement was determined by ultrasonic frequency, distance between membrane and transducer and hydraulic pressure. According to Hagon-poiseuille formula and kinematics model of pore wall in ultrasonic field, it is known that the increase of liquid flux through porous material can push much more particles into it. Finally, nano wool fabric was produced by ultrasonic, and the accuracy of our view can be seen from its scanning electronic microscope.
