Development of Thermally Comfortable Clothing for Hot and Humid Environment

ABSTRACT

Comfort is essential in sportswear, where athlete requires transportation and evaporation of sweat from body. In addition to that water vapor permeability, thermal resistance and air permeability are also inevitable elements that decide thermal comfort of sportswear. Double face knitted fabrics are usually used to make sure excellent comfort of cloth in active and sports wears. In this research, two faced knitted fabrics were prepared using standard polyester and micro denier polyester in combinations with cellulosic yarns (micro-modal, micro-tencel, modal, tencel, viscose and cotton) in inner and outer layers, respectively. The most important characteristics of thermal comfort like thermal resistance, water vapor permeability, air permeability and overall moisture management capacity (OMMC) were measured for all the double face knitted fabric samples. The investigational outcome established that the modal, micro-modal, tencel, micro-tencel, viscose and cotton yarns in combinations with standard polyester and micro denier polyester yarns affect the thermo physiological comfort characteristics considerably. The results also showed that micro denier polyester/micro-tencel combination gave best OMMC, while the air permeability of polyester/viscose, water vapor permeability of polyester/tencel and thermal resistance of polyester/modal combinations were measured to be the best. This paper elaborates the thermal comfort behavior of all possible combinations of double faced knitted fabric in detail with reasoning.

舒适性在运动服中至关重要

运动员需要运输和蒸发身体的汗液. 除水蒸气渗透性外, 热阻和透气性也是决定运动服热舒适性的不可避免因素. 双面针织面料通常用于确保运动服和运动服中布料的舒适性. 本研究采用标准涤纶和细旦涤纶, 分别在内层和外层与纤维素纱线 (微莫代尔, 微天丝, 莫代尔, 天丝, 粘胶和棉) 组合, 制备双面针织物. 测量了所有双面针织物样品的最重要的热舒适性特征, 如热阻, 水蒸气渗透性, 透气性和总体水分管理能力 (OMMC) . 研究结果表明, 莫代尔纱, 微莫代尔纱, 天丝纱, 微天丝纱, 粘胶纱和棉纱与标准涤纶纱和细旦涤纶纱的组合对热生理舒适性有显著影响. 结果还表明, 细旦聚酯/超细坦塞尔组合的OMMC最好, 而聚酯/粘胶的透气性, 聚酯/坦塞尔的水蒸气渗透性和聚酯/莫代尔组合的耐热性最好. 本文通过推理详细阐述了双面针织物各种可能组合的热舒适性.
