Effect of Air Permeability of Textile Fabrics on heat and Moisture Transfer Properties

纤维和空气空间中最大的服装材料。织物是空气中可渗透的，因为它的空气空间。这个财产与热和湿度之间的关系密切，通过结构转移。特别地，当风渗透通过服装系统进行时，通过增加空气对系统的热量和湿度转移的抵抗力（velocity.in）订购以提供绝缘织物的基本设计信息，并预测将稳定的热量从加热板（30 ° C）转移到周围（20 ° C）通过织物获得了实验和简单的热量转移模型。对于不适用的材料，由于热量转移被证明受到了质疑的影响、材料的热抵抗力、空气间隙的大小和风的速度。由于结构，特别是由于空气渗透性对热量转移的影响已经受到了质疑，而湿度已经受到了影响，也因为湿度已经受到了对混合性织物的影响。The effect of air permeability on moisture transfer begins to be displayed at the wind penetration rate of 1.58 x10 ^\-3> m/s。这一结果意味着空气渗透性在低风速度下发挥了更重要的作用。织物的空气渗透性是用于服装材料的必要属性之一。

Most of clothing materials consist of fiber and air space. Fabrics are air-permeable because of its air space. This property closely related both with the heat and moisture transfer through fabrics. Particularly, when wind penetration occurs through the clothing system, the resistance of heat and moisture transfer of the system decrease with increasing air velocity.in order to provide the basic design information of insulating fabrics, the equations predict-ing the steady heat transfer from the heated plate (30 ゜C) to the surroundings (20 ゜C) through fabrics have been obtained by the experiment and the simple heat transfer model. For impermeable materials, the effects of emissivity, thermal resistance of materials, the size of air gap, and wind velocity on the heat transfer have been discussed. For the fabrics, especially, the effect of air permeability on the heat transfer has been discussed.The empirical equation of the moisture has been obtained for hygrohobic fabrics. The effect of air permeability on moisture transfer begins to be displayed at the wind penetration rate of 1.58 x 10^<-3> m/s. This result means that air permeability plays a more important role in moisture transfer even at lower wind velocity. The air permeability of fabrics is one of the essential property to describe the performance of fabrics used for the clothing material.
