Polycaprolactone (PCL) is a biodegradable polymer widely utilized in biomedical and environmentally friendly textile applications due to its excellent biocompatibility, mechanical strength, and ability to degrade naturally in biological environments. This study aims to analyze the biodegradability and tensile strength of PCL yarn produced through the wet spinning process. A 20% w/v PCL solution was prepared by dissolving PCL pellets in chloroform and extruded through a 21G needle tip into a 96% ethanol coagulation bath at room temperature. The solidified filaments were dried and twisted into yarns with variations of 2-ply, 3-ply, and 4-ply configurations. Biodegradation was evaluated by immersing the yarn samples in a saline (NaCl) infusion solution for several weeks to measure mass loss, while tensile strength was measured following ASTM D2256 standards using a universal testing machine. The results revealed a gradual reduction in yarn mass over the immersion period, indicating effective biodegradation. Tensile strength increased proportionally with the number of plies, where the 4-ply yarn exhibited the highest strength and elongation performance. The findings confirm that wet-spun PCL yarn maintains sufficient mechanical integrity while demonstrating significant biodegradability, making it a promising candidate for biomedical sutures, bio-textiles, and sustainable polymer products. Overall, this research provides a practical understanding of the relationship between spinning parameters, mechanical properties, and biodegradation behavior in PCL-based yarns.
