Influence of acoustic vibrations of ultrasonic range on strength properties of textile materials in the processes of drying

The results of the experiments of the drying process are presented, the influence of the regime parameters of processing under the influence of acoustic vibrations of the ultrasonic range on the strength properties of textile materials is detected, which can be used in the development of practical recommendations to improve the strength properties of products. It is determined that in the drying processes there is a "threshold" value of the emitter power, which provides maximum strength for a particular material during processing. When this value is exceeded, the strength of the samples begins to decrease, which indicates damage to the microfibers of the material. Results of researches and processing of experimental data are shown in the form of empirical equations and graphs which can be used in engineering practice at a choice of modes of ultrasonic heat treatment and drying.
