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.

摘要

舒适对于运动服来说是必不可少的，因为运动服需要运输和蒸发身体的汗水。除了透湿性，热阻和透气性也是决定运动服热舒适性的必然因素。双面针织面料通常用于确保布料在运动服和运动服中的出色舒适度。在这项研究中，使用标准涤纶和微旦涤纶与纤维素纤维组合制备了两面针织面料。纱线（微莫代尔、微天丝、莫代尔、天丝、粘胶和棉）分别位于内层和外层。对所有双面针织物样品测量了最重要的热舒适性特性，如耐热性、水蒸气渗透性、透气性和整体水分管理能力 (OMMC)。研究结果表明，莫代尔、微莫代尔、天丝、微天丝、粘胶和棉纱与标准涤纶和微旦涤纶纱的组合显着影响热生理舒适特性。结果还表明，微旦涤纶/微天丝组合给出了最好的OMMC，而涤纶/粘胶的透气性，测得聚酯/天丝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面料所有可能组合的热舒适行为。
