  • Process for dyeing a textile web
    Patent number: 7674300
    Abstract: In a process for dyeing a textile web, dye is applied directly to a first face of the textile web other than by saturating the web. The web is moved in an open configuration thereof over a contact surface of an ultrasonic vibration system with a second (opposite) face of the textile web in direct contact with the contact surface of the ultrasonic vibration system and the first face free from contact with the contact surface of the ultrasonic vibration system. The ultrasonic vibration system is operated to impart ultrasonic energy to the second face of the textile web to facilitate movement of the dye from the first face of the web into and through the web to the second face thereof. In another embodiment, dye is applied to the first face of the textile web without applying the dye to the second face of the web.

  • Method of testing for ATP load in commercial laundry and for data tracking the results
    Patent number: 7628823
    Abstract: A method of testing for sanitization of textiles comprises the steps of cleaning textiles in a water solution and testing the water solution for the presence of contaminants such as adenosine triphosphate (ATP), typically with a luminometer. Typically, the water solution will be drained from a cleaning vessel and tested. Another option is the testing of the water solution extracted after draining such as by a spin cycle. The method provides improved accuracy of test results as to the level of cleanliness. In addition, testing at this early step of the laundering process allows for additional cleaning if needed without having undertaken costly and time-consuming steps such as drying. Moreover, absent re-contamination of the textiles after the cleaning process, drying and finishing procedures may be accomplished without further sanitizing the textiles.
