Comparative analysis of cartons for the substrate in special shoes of the sandal-glue method of fastening

Currently, the range of manufactured shoes of thread fastening methods for special purposes is quite diverse. Traditionally used rigid leathers for the details of the bottom of shoes of thread fastening methods increase the cost and complexity of shoe manufacturing, since they require the introduction of a large number of processing operations into the technological process. In this regard, at enterprises specializing in the production of shoes with thread fastening methods, there was a need to find a cheaper and more affordable analogue of hard leathers. The purpose of this work is to study the physical, mechanical, technological and operational properties of shelving cartons intended for shoes of thread fastening methods, in order to select the substrate material for shoes of a sandal - adhesive method of fastening for special purposes, which has the necessary set of properties. In accordance with standard methods, the physical and mechanical properties of cartons intended for shoe parts of thread fastening methods are studied: tensile strength, stiffness under static bending, water ratio and delamination resistance. The adhesive ability of the cartons and the optimal stitching frequency were determined, which ensures the normative strength of the thread seam. The analysis of physical and mechanical properties, the results of production testing and experimental wear showed that Ibisolex cardboard can be used for the substrate in shoes of the sandal - adhesive method of fastening, since it has the necessary complex of properties, reduces the complexity of shoe manufacturing and its cost.
