A process for treating a textile web, said textile web having a first face, a second face opposite the first face, and a thickness, said process comprising: applying a first treatment agent to the textile web; moving the web with the first treatment agent applied thereto in an open configuration thereof over a contact surface of an ultrasonic vibration system with the textile web in direct contact with the contact surface of the ultrasonic vibration system; operating the ultrasonic vibration system to impart ultrasonic energy to said textile web to facilitate the distribution of said first treatment agent through a first extent of said thickness of the textile web; applying a second treatment agent to the textile web other than by saturating the textile web with said second treatment agent; moving the web with the second treatment agent applied thereto in an open configuration thereof over a contact surface of an ultrasonic vibration system with the textile web in direct contact with the contact surface of the ultrasonic vibration system; and operating the ultrasonic vibration system to impart ultrasonic energy to said textile web to facilitate the distribution of said second treatment agent through a second extent of said thickness of the web, said second extent being different than said first extent such that at least a portion of the first extent of the thickness of the textile web is free from the second treatment agent.
