Abstract

In a process for dyeing a textile web having a first face and a second face opposite the first face, dye is applied to the textile web and the web is then moved 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. The ultrasonic vibration system is operated to impart ultrasonic energy to the textile web to facilitate the distribution of dye throughout the web. The web is then moved further in its open configuration through a microwave application chamber of a microwave system and the microwave system is operated to impart microwave energy to the web in the microwave application chamber to facilitate binding of the dye to the web.
