中文摘要
由于在人体健康和舒适性方面巨大的科学价值和应用潜力,能在高温下吸湿排汗的单向导湿Janus面料成为当前国际研究热点。然而现阶段基于由内而外润湿梯度的单一模式Janus面料缺乏湿热管理协同性和环境适应性,难以应对日常室内外冷热切换,且制备过程和服用性能难以满足大规模的实际应用。本项目拟将温敏高分子与双层针织结合,精确构建具有可逆Janus导湿梯度和可变孔结构的湿热管理面料,根据环境温度变化智能调节汗液传导和热对流强度,实现高温下湿热释放,低温下控湿保温,并保持优良服用性能。通过研究温敏高分子聚合-交联体系对纱线润湿性及体积变化的影响规律、以及针织结构对可逆导湿Janus构型和可变孔结构的调控机制,揭示纱线性质、织物结构对于温度变化下的汗液传导与蒸发、热对流及皮肤粘附的作用机理,建立湿热动态协同管理模型。本项目的研究将为功能高分子改性及其在织物的健康和舒适性设计方面提供科学依据和新思路。
英文摘要
Janus fabrics capable of unidirectional sweat wicking under hot weather have gradually become a current international research hotspot due to the huge scientific value and application potential in terms of human health and comfort. However, the existing single-mode Janus fabrics based on the increasing wettability from inner to outer side lack the synergy and environmental adaptability of moisture/thermal management, making them difficult to cope with the daily switching between outdoor heating and indoor cooling situations. Besides, the current fabrication processes and wearability are difficult to meet large-scale practical applications. Herein, we propose a research on accurately fabricating a Janus fabric featuring with reversible Janus wettability gradient and adjustable pore structures by combining thermal-responsive polymers with knitting technology. It can adjust sweat transportation and heat convection upon temperature change to realize moisture/heat dissipation or preservation in hot or cold environment, respectively. The wearability can also be ensured. The investigation on the effect of polymerization-crosslinking system on the yarn wettability and volume changes, and the regulating mechanism of knitting structure on the reversible water-transport Janus configuration and variable pore structure will be performed to reveal the managing mechanism of sweat transportation/evaporation, heat convection, and skin adhesion under temperature changes. The simulation model of dynamic and synergetic moisture/thermal management can be established in consequence. We envision this research will provide significant guidance and new ideas in designing functional polymer based smart fabrics applied in human health and comfort.
