用Wilhelmy原理测定羊毛表面亲水性的研究

A Study on Hydrophilic Property Determination of Wool Surface by Wihelmy Principle

应用Ｗｉｌｈｅｌｍｙ原理对羊毛表面的亲水性能测定，结果稳定可靠。研究表明动物毛发表面具有疏水性，粗毛、发毛的亲水性好于细绒毛，细绒毛中澳毛的亲水性略好于国产羊毛。

Wihelmy Principle was used to determine the hydrophilic property of wool surface in this paper. It indicated that equilibrium contact angle could be well and truly determined by Wihelmy principle, so the determining way designed would be an implementation in evaluating the chemical modiffication effect of wool. The results revealed slight difference of hydrophilic property between different wool variety. In general, the coarse wool and bristle wool appeared more hydrophilic than fine wool, and the Australian wool, a little betterthan the Chinese wool.
