Thermal and Comfort Properties of Polyester/micro-polyester and Cotton/regenerated Fibers Blended Knitted Fabrics

ABSTRACT

Thermo-physiological comfort of textile is related to thermal equilibrium between environment and human body and also provides a balance between the heat production of body and loss of heat. During working actions executed in hot conditions, body produces heat energy in large amount which increase the temperature of body. In consequence, body perspires in vapor and liquid form to reduce the temperature of the body. Thus the clothing requires next to the skin should have the capacity to allow the passage of heat and perspiration through it. Otherwise, it will cause the discomfort for the workers who work in hot environment. That is why the moisture management, air permeability, thermal resistance, and water vapor permeability of the fabric wear next to the skin are very important to maintain the thermal comfort of the worker. In this study eight different type of pure yarns were produced in which two are syntactic and other six are cellulosic and regenerated cellulosic. The six single jersey knitted fabrics were produced from the pure standard polyester yarn combination with cellulosic and regenerated cellulosic yarns through the single feeder of the sample knitting machine. The other six samples were produced from the pure micro polyester yarn combination with cellulosic and regenerated cellulosic yarns. The different tests were performed on the samples to evaluate the thermal comfort properties of the fabrics. The results showed that the single jersey knitted fabric produced from the pure micro polyester yarn combined with the pure tencel yarn provide good all over properties for the hot environment next to skin wear.

摘要

纺织品的热生理舒适性关系到环境与人体之间的热平衡, 也提供了人体热量产生与热量损失之间的平衡. 在高温条件下进行工作时, 人体产生大量热能, 从而提高人体温度. 结果, 身体以蒸气和液体的形式出汗, 以降低身体温度. 因此, 靠近皮肤的衣服应具有允许热量和汗水通过的能力. 否则, 会给在高温环境下工作的工人带来不适. 这就是为什么靠近皮肤的织物的水分管理、透气性、耐热性和水蒸气渗透性对于保持工人的热舒适性非常重要的原因. 在这项研究中, 生产了8种不同类型的纯纱线, 其中两种是复合纱线, 另外6种是纤维素和再生纤维素纱线. 采用纯标准涤纶纱线与纤维素和再生纤维素纱线通过样品针织机的单喂入器结合, 生产出六种单针织物. 另外6个样品由纯微涤纶纱线与纤维素和再生纤维素纱线组合而成. 对样品进行了不同的测试, 以评估织物的热舒适性. 结果表明, 由纯超细涤纶纱与纯tencel纱组合而成的针织单件针织物, 在紧贴皮肤的高温环境下具有良好的综合性能.
