In this study, the mechanical properties of multifilament thermoplastic yarns produced from polyester polyols-based thermoplastic polyurethane (TPU) polymer in a pilot melt spinning machine were ingestigated at different winding speeds.

Elastic fibers are products that are widely used in the textile industry. They are generally used in activewear, sportswear and denim products. The best known in the industry are elastane or spandex. The most common technique used to produce elastane is dry spinning. However, in this technique, harmful solvents and chemicals are used during production and the degradation time of elastane in nature is quite long. In polyester polyols based thermoplastic polyurethane production, there is no need for water or solvents and thermoplastic polyurethane is a more environmentally friendly and ecological fiber. In this study, trial studies were carried out at different winding speeds using the melt spinning method. After fiber production at certain winding speeds, mechanical, physical and thermal analyses were performed to understand how the winding speed affects the properties of the fibers such as tenacity, elongation at break, linear density, melting point, etc.
