Synergistic Design of Linen/Cotton Blended Knitted Fabrics for Sustainable Moisture-Regulating Sportswear
摘要
The increasing demand for sustainable sportswear has accelerated the exploration of natural fiber alternatives to synthetic materials. This study investigates the development and performance evaluation of linen/cotton (LC)-blended knitted fabrics for moisture management and mechanical properties in sportswear applications. Five fabric compositions were developed using ring-spun yarns: 100% cotton, 100% linen, and three blends (LC75/25, LC50/50, and LC25/75). The developed samples were then characterized for their physical, mechanical, air permeability, and moisture management properties using standardized testing methods with statistical validation. Results demonstrate that increasing linen content significantly enhances moisture management performance. The 100% linen fabric achieved the highest overall moisture management capacity (0.80), fastest spreading speed (5.6 mm/s), and shortest wetting time (4.5 s). The 75/25 linen/cotton blend showed optimal balance with 94% of linen’s moisture management performance while maintaining improved softness. Mechanical testing revealed that the 50/50 blend exhibited superior breaking strength (268 N), representing a 49% and 123% improvement over pure linen and cotton, respectively, demonstrating synergistic reinforcement. Air permeability marginally increased with linen content. Statistical analysis (ANOVA, p < 0.05) confirmed significant differences between all blend ratios for moisture management parameters. These findings establish linen-rich blends as viable eco-friendly alternatives for functional sportswear, combining superior moisture management with enhanced mechanical durability compared to pure fibers.
