New textile structures based on sustainable fibers spinning

This thesis investigates innovative approaches to sustainable fiber production within the textile industry's environmental context, circular economy principles, and the utilization of eco-friendly polymers. The study explores natural and synthetic polymers, polymers dissolution in aqueous systems, protein-based fibers, and spraying systems, all within the framework of addressing pollution challenges and advancing circular and sustainable practices. Conducted under Wast2Biocomp, specifically within Work Package 3 (WP3), the research aims to identify novel fiber structures suitable for textile production, emphasizing sustainability and circular economy principles. Two distinct approaches, spraying and wet-spinning, were employed for fiber production. Materials investigated in the spraying process included PVA, chitosan, and collagen. Wet-spinning utilized a NE-1000 Multi-PhaserTM programmable syringe pump (Firmware Version: V3.923), and chitosan and collagen were also subjected to the spraying process. Characterization of the fibers involved a comprehensive set of tests, including Scanning Electron Microscopy (SEM) images, Energy-Dispersive X-ray Spectroscopy (EDS), diameter measurement, linear mass assessment, and tenacity analysis. These tests contribute to a thorough understanding of the physical and chemical properties of the developed fibers. The findings offer valuable insights into the feasibility of utilizing sustainable fibers in textile production, contributing to ongoing efforts in the textile industry towards environmental sustainability and circular practices.
