A Study on Thermal Comfort Properties in Knit Fabrics Made from Cattail and Cotton Blends
摘要
The present study examined cotton–cattail knitted fabrics concerning their thermal comfort properties through their interaction with blend ratios and knit structures. The features of cotton—hygroscopic and breathable—together with its insulating properties that cattail brings could be effective, potentially giving rise to applications in climate-specific sportswear. Three blend ratios (90:10, 80:20, and 70:30) and three knit structures (Rib, Interlock, and Loop Knit Fleece) were reviewed for air permeability, water vapor permeability, thermal resistance, and thermal conductivity. Rib Knit, using a 90:10 blend, exhibited the highest air permeability and water vapor permeability because of open structure and cotton content; thus, it can be suitable in warm climates. The Loop Knit (Fleece) with a 70:30 blend showed the highest thermal resistance and the lowest thermal conductivity due to its dense pile structure and the contribution of cattail fibers; thus, it could be the best in cold climates. Interlock structures with an 80:20 blend presented moderate performance, giving a balance to insulation properties paired with moisture management, for temperate conditions. These findings emphasize the ability of sustainable cotton–cattail blends to provide sporting apparel with comfort properties matching climatic demands. Current study findings establish the combined effect of fiber composition and fabric structure on thermal comfort, promoting innovation in eco-friendly applications.
