Sustainable polymers for biobased yarns: process development in melt spinning for Nylon 6.10 and PLA

The growing emphasis on sustainability within the textile industry necessitates the exploration of eco-friendly materials to reduce environmental impact and resource consumption. This study focuses on the development of biobased yarns using Nylon 6.10 and Polylactic Acid (PLA) via melt spinning techniques. These polymers were chosen for their renewable origins and potential to decrease reliance on fossil fuels. Through process optimization and parameter analysis, the research evaluates yarn properties such as tensile strength, elasticity, and thermal stability. Nylon 6.10 demonstrated superior mechanical performance, with high tensile strength and flexibility, making it ideal for technical applications. In contrast, PLA exhibited greater stiffness but at the cost of reduced flexibility and tensile strength, positioning it as a more sustainable option for applications requiring structural stability. The findings contribute to advancing sustainable textile manufacturing by offering valuable insights into the feasibility of using these biobased polymers, supporting innovation and the integration of eco-friendly materials into textile production.
