Process for applying one or more treatment agents to a textile web

A process for treating a textile web, said textile web having a first face and a second face opposite the first face, 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 in a longitudinal direction of the web 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 within the textile web;
• applying a second treatment agent to the first face of the textile web;
• moving the web with the second treatment agent applied thereto in an open configuration thereof in a longitudinal direction of the web 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 distribution of the second treatment agent within the web from the first face of the textile web toward the second face thereof, said distribution being non-uniform across a transverse direction of the web such that the first treatment agent extends over a greater transverse portion of the textile web than the second treatment agent.
