Kinetics of contact ultrasonic drying of thick woolen fabric

The article is devoted to an experimental research of the effectiveness continuous contact ultrasonic drying dense woolen fabrics. For drying, stand was created in form a small-sized continuous-action machine. In process, dried fabric rewound from reel reel, through zone (150 W) and thermal (at temperatures 50 °C 80 °C) exposure. It has been established that action (together with thermal) provides reduction time 18% 28%. Moreover, at lower temperature, contribution vibrations higher. schedules were approximated by formula expressing dependence moisture content material on temperature presence resulting approximation can be used analyze curves convective fabrics, taking into account agent exposure, including predicting duration such types drying.
