Full textIn this master's dissertation an analytical study of the ultrasonic means of technological control of tissue surface density. The analysis showed that to ensure the release of quality fabrics it is necessary to carry out operational technological control of their surface density. Currently, mainly destructive contact methods of tissue surface density control are used, which are based on cutting and weighing tissue samples, while non-contact ones are not used, although they have a number of significant advantages over contact ones. As shown by the analysis conducted in the first section of the dissertation, for the operational technological control of tissue surface density, it is advisable to use ultrasonic control methods. The second section of the dissertation discusses the peculiarities of the propagation of ultrasonic waves in tissues, which are related to the pore size and other structural parameters of tissues that affect the passage of ultrasonic waves through the tissue and reflection from it. A study of the passage of ultrasonic waves through controlled tissues with different pore sizes and reflections from them and obtained analytical dependences for the calculation and analysis of the interaction of ultrasonic waves with tissue threads with different acoustic resistances. Analytical dependences are obtained, which relate the amplitude ratios of ultrasonic waves both with the change of the diameters of the warp and weft threads, and directly with the surface density of the fabric. It has been shown that the attenuation of ultrasonic vibrations can be neglected for most tissues, and the choice of the ratio of the bulk density of the tissue and the length of the ultrasonic wave in the fabric can reduce the effect of attenuation on the amplitude ratio of ultrasonic waves. It is shown that as the duration of the ultrasonic pulse signal increases, the amplitude and phase errors decrease in comparison with the continuous signal. Therefore, it is necessary to choose the duration of the ultrasonic pulse signal so that there are no reflections of ultrasonic waves from the surface of the fabric and the surfaces of the piezoelectric transducers. In the third development of ultrasonic means of technological control of surface density of fabrics and its experimental researches is carried out.
