This book examines issues of improving the efficiency of the control technological parameters of textile materials through with computerized systems with the application of non-contact methods as only they allow to react quickly to changes of technological parameters during production. The original models, algorithms, software and hardware of the developed system for the control technological parameters of textile materials are presented. Also, the book presents new methods for measuring the technological parameters of textile materials, which do not need require taking into account the constant readjustment of the system to controlled samples of materials with different structure and porosity. The developed model of the computerized system allows contactless control of basis weight and porosity of fabrics in the course of their production. This book contains six chapters, for researchers, engineers, as well as lecturers and postgraduates of higher education institutions dealing with ultrasonic control engineering equipment.
