Abstract
The article presents the results of a study on the application of elastic polyurethane yarns in textile materials used for manufacturing garments for various purposes. The study examines the combination of polyurethane yarns with natural and synthetic fibers, as well as their role as functional components of the yarn. The methodology includes an analysis of scientific and technical literature, systematic and comparative analysis, and synthesis of experimental data.During the study, the structural characteristics of fabrics containing small amounts of polyurethane yarns embedded within the weave structure were investigated. It was established that incorporating polyurethane yarns increases fabric elasticity, improves garment shape retention, reduces wrinkling, and enhances wearing comfort. Garments made from such fabrics exhibit good body fit, resistance to deformation, and maintain their original shape during wear.The results have practical significance and can inform the design and production of modern garments with improved performance and consumer properties. Using polyurethane yarns in textiles allows for the development of garments that meet functional, comfort, and aesthetic requirements.
