Abstract: Based on the unidirectional moisture conduction mechanism, a unidirectional moisture conduction woven fabric with polyester fiber as raw material is designed and used for trial woven. According to the analysis of influencing factors such as fiber material and warp and weft yarn distribution, an evaluation method suitable for polyester woven fabric is proposed. The capillary effect height of warp and weft raw materials and the distribution of different kinds of fibers in the fabric are measured and calculated, and the unidirectional moisture conductivity U value which can reflect the unidirectional moisture conductivity of single-layer woven fabric is obtained. The smaller the U value, the stronger the unidirectional moisture conductivity of the fabric. Through linear regression analysis and correlation coefficient calculation, the U value matches well with the unidirectional moisture conductivity of the sample.

Key words: woven fabric, unidirectional moisture conduction, capillary effect, fiber distribution, evaluation method

摘要： 基于单向导湿机理设计并试织了以涤纶纤维为原料的单向导湿机织物,根据纤维材料、经纬纱线分布等影响因素的分析提出了一种适用于涤纶机织物的单向导湿性能评价方法。通过对织物经、纬原料毛细效应高度以及不同种类纤维在织物中的分布情况进行测量计算,得到可以反映单层机织物单向导湿能力的单向导湿系数U值。U值越小,织物单向导湿能力越强。经线性回归分析与相关系数计算,U值大小与试样单向导湿性能强弱匹配良好。
