Producing Nonwoven Materials for the Shoe Industry.

The objective of this research was to optimize the process of producing nonwoven fabrics for shoe industry with good hygienic and deformation and strength properties. The task of the research was to study the influence of various types of fibrous raw materials, the content of hydrophilic fibres in the mixture and other technological parameters on the properties of nonwoven thermally bonded materials. Various fibres mixtures have been produced, deformation and strength and functional properties of nonwoven thermally bonded fabrics have been studied, optimal conditions for the production of nonwoven materials for the shoe industry have been experimentally established, mathematical dependencies of the operational properties of nonwoven shoe materials on the technological parameters of production have been determined. It has been established that depending on the material purpose and the requirements put to it, the optimal technological parameters for the production of nonwoven shoe materials are selected for the particular case in order to achieve the best quality indicators of products.
