亲水性疏水性织物动态热湿舒适性比较研究

以纯毛织物作为亲水性织物的代表、以纯涤纶织物作为疏水性织物的代表，利用织物动态热湿舒适性能测试仪，采用定量汗液蒸发的方法，研究了两类织物的动态热湿舒适性能，并对两者的差异进行了理论分析。研究表明：在动态条件下由于皮肤要经历干燥—出汗—蒸发—干燥、织物要经历干燥—吸湿—放湿—干燥的过程，此时，亲水性的吸湿性好的织物对汗液的蒸发起了阻碍作用，因此动态条件下使用疏水性的织物比使用亲水性的织物更趋合理。

服装热湿舒适性和材料的热湿传递特性(摘要)

服装的热湿舒适性是指人体着装后在不同的气候环境中,人体与环境间不断进行热湿能量交换,在这种能量交换达到平衡时,人体感到既不冷又不热,既不闷又不湿的舒适满意的一种性能。服装在热湿能量交换中起着重要的调节作用,随着服装调节作用的进行,经过物理。生理、心理等因素的相互复杂作用,使人体处在感到舒适满意的热湿平衡中。在这种状态下,人的各种器官才能处于正常生理状态,才能进行正常的工作和生活。服装热湿舒适性是人、服装、环境之间的生物热力学的综合平衡,是环境气候条件、人体活动水平、服装款式和服装材料性能等多种因素的综合协调。其中构成服装的物质基础——服装材料的热湿传递特性是影响服装舒适性的重要因素。本文以人体为基本出发点,通过对人体生理——服装功能——环境气候之间关系的分析,探讨了服装热湿舒适性的形成机理,并就服装材料的热湿传递特性及其对服装热湿舒适性的影响进行了讨论。

Study on the Factors to Influence Dynamic Heat - moisture Comfort of Summer Clothing Fabrics

In this paper, the factors to influence the dynamic heat - moisture comfort of summer clothing fabrics have been studied. It is pointed out that, when the wind speed outside is high, or the air permeability is very good, the sweat of human body will evaporate mainly through turbulent diffusion. Because of the rapid sweat evaporation, human body will feel cold, and then, the difference in temperature and humidity of the micro - climatic section will be very slight. On the contrary, when the wind speed outside is slow or the air permeability is unsatisfactory, the sweat of human body will evaporate mainly through molecular diffusion, and in this case, the humidity of the micro - climatic section will be depended on the hygroscopicity of the fabric, that' s to say, the better the hygroscopicity, the lower the humidity. It is difficult for pure wool fabric to loss heat because of its giving out much heat during the course of moisture - absorption in the initial stages of sweating. For pure polyester fabric,

Study on Dynamic Heat-moisture Transfer Properties of Summer Fabrics Using Microclimatic Method

The temporature and humidity of the microclimatic zone of summer fabrics in the course of sweating - evaporating -drying were measured with an apparatus specially made for the purpose. It is pointed out that temperature and humidity changes in quantitative perspiration evaporation process in the microclimatic zone can express the dynamic heatmoisture comfortability. Characteristic values include temperature decline speed, temperature rising speed, humidity rising speed, humidity balance value, and humidity decline speed. Fabrics with good air permeability are beneficial to improving comfortability of summer fabrics, while temperature rising speed and humidity decline speed in the microclimatic zone of thick and heavy fabrics with good hygroscopicity are relatively slow. Through comparing fabrics‘ dynamic heat-moisture curves obtained respectively with Microcllmatic Method and Heat Loss Method, the two methods are identical essentially.     

Gray Synthetic Evaluation on Moisture Comfort of Sportswear Fabrics under the Condition of Heavy Sweating

Moisture and water transfer under the condition of heavy sweating are analyzed. Four different experiments are made to test moisture resistance, water-keep, wicking effect and drying ability of samples. Then gray analysis method is introduced to evaluate the comprehensive comfort of these fabrics. Result shows chemical fiber with high moisture transfer performance has advantage in water transfer and diffusion, which is suitable for human under the condition of heavy sweating. Though natural fiber can absorb moisture well, it cannot transfer fluid sweat. Therefore natural fiber fabrics such as cotton, wool are unsuitable to make functional sportswear.
