Abstract

At present, the use of wool-based nonwoven materials for footwear components is both effective and relevant in the footwear industry. Wool felt is a natural material characterized by high thermal insulation, insulating, and strength properties; moreover, sheep wool used in felt production is inexpensive and readily available. This article presents a study aimed at determining the physical and mechanical property indicators of wool-based nonwoven materials intended for footwear components. The dimensional and structural characteristics of felt materials produced by domestic manufacturers were determined. Samples of three types of nonwoven materials were prepared; the fibrous composition of each sample was examined using optical microscopy, tensile characteristics were determined, and thickness measurements and density parameters were calculated. Based on the research results, compared with the other studied samples, Sample No. 1 made of pure wool demonstrated the highest tensile strength indicators.
