Bereznenko S. Fundamentals of resource-saving technological processes of moulding and imparting permanent shape to garment parts made of anisotropic textile materials.

The thesis deals with the problem of improving the processes of moulding and imparting permanent shape to garment parts made of anisotropic textile materials. The scientific basis of the solution includes the results of the theo-retical foundation of interrelations of different types of anisotropy of textile materials, conditions of reaching the transverse-isotropic state of packages which have been determined using the methods of tensor transformations, the principles of superposition and the methods of Q-functions developed in the paper, the solution of the tasks of garment parts vibration moulding in terms of the method of hydrodynamic analogies and the theoretic foundation of mould-ing complex curvilinear surfaces of textile materials packages by the method of static and dynamic influence on the fine and coarse structure of textile materi-als. As a result of experimental investigations the chief theoretical conclusions have been proved to be correct and new data on physico-mechanical and rheological properties of monolayers of textile materials and packages based on them have been obtained, these have been determined by up-to-date static and dynamic testing methods; chief parameters of garment parts vibration mould-ing processes when being influenced by the transverse electromagnetic field (fregnancy, amplitude, magnetic induction, phase shift) and conditions of establishing viscose elasticity fields of the required configuration, metastable state of packages depending on the direction of deformation loading. The data obtained make up the basis for creating new energy-saving equipment for garment pressing and suggest methodological foundation of the proper selection of materials for packages with the appropriate visco-elastic characteristics.
