【摘要】 研究开发生物基聚酰胺凉感集圈组织针织面料，以生物基聚酰胺PA56、凉感涤纶纱为原料，通过集圈织造工艺，面料上矩阵式布置芯吸结构，赋予面料良好的抗皱性、透气性和弹性，提升穿着舒适感。经测试，面料接触瞬间凉感值Q_max达到0.24 W/cm²，透湿率1.00×10⁴g/（m²·24 h），面料具有较好的凉感和透气导湿性能。采用的生物基聚酰胺PA56能够减少对石油的依赖以及二氧化碳的排放，符合未来新型材料的发展趋势。更多还原

【Abstract】 A knitted fabric featuring a tuck stitch structure with cool feel was developed using bio-based polyamide PA5 and cooling polyester yarns as raw materials. By optimizing the tuck knitting process, a wicking matrix structure was engineered on the fabric surface to impart excellent wrinkle resistance, air permeability and elasticity, thereby enhancing wearing comfort. Performance tests indicated that the fabric achieved a Q_max value of 0.24 W/cm² for instantaneous cooling sensation and a moisture permeability of 1.00×10⁴g/（m²·24 h）. These results demonstrate superior cooling properties and excellent moisture permeability. Furthermore, the utilization of bio-based polyamide PA56 mitigates reliance on petroleum resources and reduces carbon dioxide emissions, aligning with the sustainable development trends of advanced textile materials.更多还原
