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.

1. A process for dyeing a textile web, said textile web having a first face and a second face opposite the first face, said method comprising: applying dye to the textile web, wherein the dye has a dielectric loss factor at 900 MHz and 22 degrees Celsius of at least about 5;moving the web 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 dye throughout the web;moving the web in its open configuration through a microwave application chamber of a microwave system subsequent to imparting ultrasonic energy to said web, wherein the web is moved through the microwave application chamber at a rate relative to a microwave application chamber length to define a dwell time of the web within the chamber in the range of about 0.0002 seconds to about 3 seconds; andoperating the microwave system to impart microwave energy to the web in the microwave application chamber to facilitate binding of the dye to the web. 2. The process set forth in claim 1 wherein the step of applying dye to the textile web comprises applying dye to the first face of the web other than by saturating the web. 3. The process set forth in claim 2 wherein the step of moving the web over the contact surface of an ultrasonic vibration system comprises moving said web of said contact surface with the second face of said web in direct contact with said contact surface of the ultrasonic vibration system. 4. The process set forth in claim 1 wherein the ultrasonic vibration system has a longitudinal axis, the textile web being moved in a machine direction from a location upstream from the contact surface of the ultrasonic vibration system into contact with the contact surface of the ultrasonic vibration system, said movement of the web in the machine direction being along an approach angle relative to said longitudinal axis of the ultrasonic vibration system, said approach angle being in the range of about 1 to about 89 degrees. 5. The process set forth in claim 4 wherein the approach angle is in the range of about 10 to about 45 degrees. 6. The process set forth in claim 4 wherein the textile web is further moved in the machine direction along a departure angle relative to the longitudinal axis of the ultrasonic vibration system from said contact of the web with the contact surface of the ultrasonic vibration system to a location downstream from said contact surface of the ultrasonic vibration system, said departure angle being in the range of about 1 to about 89 degrees. 7. The process set forth in claim 1 wherein the textile web has a width, the process further comprising holding the textile web in uniform tension across the width of the textile web at least at a portion of said textile web in direct contact with the contact surface of the ultrasonic vibration system, said tension being in the range of about 0.025 to about 3 pounds per inch of width of the textile web. 8. The process set forth in claim 1 wherein the ultrasonic vibration system is vibrated at a frequency in the range of about 20 kHz to about 40 kHz. 9. The process set forth in claim 1 wherein the step of operating the ultrasonic vibration system comprises supplying a power input to said system, the power input being in the range of about 0.5 kW to about 2 kw. 10. The process set forth in claim 1 wherein the textile web has a width, the ultrasonic vibration system comprising an ultrasonic horn having a terminal end defining said contact surface, said terminal end of the ultrasonic horn having a width that is approximately equal to or greater than the width of the web, the step of moving the web in an open configuration thereof over the contact surface of an ultrasonic vibration system comprising moving the web lengthwise over the contact surface of the ultrasonic vibration system with the terminal end of the ultrasonic vibration system oriented to extend widthwise across the width of the web with the contact surface in direct contact with the web. 11. The process set forth in claim 1 wherein the step of operating the microwave system comprises operating the microwave system at a frequency in the range of about 900 MHz to about 5,800 MHz. 12. The process set forth in claim 1 wherein the step of operating the microwave system comprises operating the microwave system at a power input in the range of about 1,500 watts to about 6,000 watts. 13. The process set forth in claim 1 wherein the step of applying dye to the textile web comprises applying a dye having a dielectric loss factor at 900 MHz and 22 degrees Celsius of at least about 10 to the textile web. 14. The process set forth in claim 13 wherein the step of applying dye to the textile web comprises applying a dye having a dielectric loss factor at 900 MHz and 22 degrees Celsius of at least about 14 to the textile web. 15. The process set forth in claim 1 wherein the step of applying dye to the textile web comprises applying a dye having a dielectric loss factor at 2,450 MHz and 22 degrees Celsius of at least about 10 to the textile web. 16. The process set forth in claim 15 wherein the step of applying dye to the textile web comprises applying a dye having a dielectric loss factor at 2,450 MHz and 22 degrees Celsius of at least about 15 to the textile web. 17. A process for dyeing a textile web, said textile web having a first face, a second face opposite the first face and a thickness from said first face to said second face, said method comprising: applying dye to the textile web throughout the thickness thereof, wherein the dye has a dielectric loss factor at 900 MHz and 22 degrees Celsius of at least about 5;moving the web in an open configuration thereof through a microwave application chamber of a microwave system subsequent to applying dye to the web, wherein the web is moved through the microwave application chamber at a rate relative to a microwave application chamber length to define a dwell time of the web within said chamber in the range of about 0.0002 seconds to about 3 seconds; andoperating the microwave system to impart microwave energy to the web in the microwave application chamber to facilitate binding of the dye to the web. 18.
