摘要：

为探索毛织物的孔隙特征对其透湿性的作用机制,建立毛织物孔隙特征与其透湿性的经验关系模型,采用体积孔隙率、表面孔隙率和平均孔径分别从不同角度对毛织物的孔隙特征进行表征,用湿阻表征织物透湿性;分别测试了24种毛织物试样的孔隙指标和湿阻;最后分别建立各孔隙特征指标与湿阻的多项式回归模型。得到的经验关系曲线表明:3个织物孔隙特征指标分别与湿阻呈一定程度的非线性相关性,且都呈先正相关后负相关的特征,即湿阻在一定区域存在最高值;当体积孔隙率为60%时湿阻进入最高值区域;当表面孔隙率超过1.5%时,其对湿阻的影响关系开始明显,表面孔隙率在3%附近湿阻呈最高值;当平均孔径在45 μm左右时,湿阻到达最高区域。

Abstract:

In order to investigate on the influence mechanism of the capillary structure on moisture permeability of wool fabrics, empirical models describing the relationship between capillary characteristics and moisture permeability of wool fabrics were built. Three indices of volume porosity, surface porosity and the average pore size were adopted to describe capillary characteristics of wool fabrics from different aspects. And the index of wet resistance was used to represent the moisture permeability of fabrics. For twenty-four types of wool fabric samples, the capillary characteristic indices were measured as well as wet resistance. Finally, polynomial regression analysis was conducted between each capillary characteristic index and the wet resistance index. The obtained empirical relationship curves present similar tendencies. The indices of volume porosity, surface porosity and the average pore size present nonlinear correlations with wet resistance to a certain extent respectively. Along with the growth of each capillary index, the wet resistance first shows positive correlation and then negative correlation. That is, the wet resistance reaches a maximum value in certain regions. For the volume porosity-wet resistance relation curve, the wet resistance reaches maximum when the volume porosity is about 60%. The surface porosity-wet resistance relationship gets clear when surface porosity rises beyond 1.5%, and at about 3% of surface porosity, the wet resistance reaches maximum. Similarly, the wet resistance stops increasing as the average pore size arises to about 45 μm.

Key words: wool fabric, moisture permeability, capillary characteristic, wet resistance
