将模型哺乳动物毛发纤维的液滴润湿效果与光滑圆柱体毛发纤维的润湿效果进行了比较。(B.J.Carroll，J.Collodo界面科学，1976，57,488)。所考虑的模型具有一系列沿纤维长度规则间隔的轴对称锯齿，这些锯齿被证明在系统的润湿行为中发挥重要作用，主要是因为它们能够充当液滴两端的三相接触线的‘铰接点’。结果表明，在某些情况下，系统中的表观接触角与真实接触角和纤维粗糙度几何形状有关。因此，应该可以从经验上估计系统的真实接触角，并给出了支持这一结论的实验结果。
The wetting by a liquid drop of a model mammalian hair fibre is compared with that of a smooth cylindrical fibre. (B. J. Carroll, J. Collodid Interface Sci., 1976, 57, 488). The model considered has a series of axially symmertrical serrations regularly spaced along the fibre length and these are shown to play an important role in the wetting behaviour of the system, principally through their ability to act as points of ‘hingeing’ for the three-phase contact lines at the two ends of the liquid drop. It is shown that the apparent contact angles in the system can in certain cases be related to the true contact angle and to the geometry of the fibre asperities. It should thus be possible to estimate empirically the true system contact angle and experimental results are presented in support of this conclusion.
