Abstract
A process for treating a textile web includes applying a first treatment agent to the web. The web is moved in an open configuration over a contact surface of an ultrasonic vibration system. The ultrasonic vibration system is operated to impart ultrasonic energy to the textile web to facilitate the distribution of the first treatment agent through a first extent of the thickness of the textile web. A second treatment agent is applied to the web. The web is moved in an open configuration thereof over a contact surface of an ultrasonic vibration system. The ultrasonic vibration system is operated to impart ultrasonic energy to the textile web to facilitate the distribution of the second treatment agent through a second extent of the thickness of the web. The second extent is different than the first extent.
