Capillary Volume and Evaporation of TextileMaterials

摘要

The objectives of the paper were to show that the evaporation intensity of water can be increased by the application of appropriate textile materials. The purpose was to determine the dependence of the evaporation intensity on the textile characteristics and the influence weather conditions on the evaporation intensity of different textiles. Five different textile strips of different widths and of single- and multi-layer were tested in definite experimental pots under open air conditions. The resultsof the experiments showed the total evaporation surface of the textiles depended on the texture material and the capillary volume of the textiles and the capillary volume had a limit at approximately V_c = 1000 - 1200 cm~3/m~2. Another important resultwas that the relative air humidity is a main factor of the weather conditions that has principal influence on the evaporation intensity. However, the other parameters - such as temperature, solar radiation and wind speed - have only a secondary effect onthe evaporation intensity of textiles.
