摘要

This study investigates the use of easily accessible nano-biological materials with color change capabilities, antioxidant properties, and antibacterial characteristics. Utilizing electrospinning technology, curcumin-loaded composite elastic polyurethane nanoparticles were prepared and successfully integrated into pre-combed cotton web through a spraying and bonding process. Subsequently, the yarn was produced using traditional spinning methods, including coarse and fine yarn spinning. Cotton webs loaded with varying curcumin contents (1%, 2%, 3%, and 4% by mass) were successfully formed at a feed rate of 60 mm/s. The micro-morphology, macro properties, and functional characteristics of these webs were examined post-yarn spinning at 25 °C and a relative humidity of 60%. Scanning electron microscopy observations indicated that as the curcumin loading content increased, the distribution of curcumin nanoparticles on the cotton fiber surface became more uniform. This research seeks to address the effective loading of curcumin nanoparticles into yarn and to explore the impact of curcumin content on the properties of the resultant yarn.
