ABSTRACT:
A method and apparatus for the treatment of fabric materials with a liquid finishing agent such as a liquid repellant is disclosed. The method involves passing a strip of the fabric through a bath of the liquid finishing agent across a stationary fabric contacting surface. In the preferred embodiment, the fabric is subjected to ultra-sonic energy while immersed in the bath at a power level and frequency such that cavitation occurs in the bath adjacent the submerged material.
