Abstract
It is well recognized that the wicking of liquids in a textile fabric takes place mainly through a capillary systemcomposed of the individual fibers. Considering typical dyeing stages, it is thought that a high dye uptake on the fabric prob-ably depends on the wickability. Three kinds of barely water soluble ketones, acetophenone(A), 2-pentanone(2P) and 3-14. Wicking heights of dyeing solutions were measured under such conditions that the effect of gravity was negligible.The result could be graphed as a series of straight lines having the form s = kt1/2, where s was distance traveled by thesolutions, t was time, and k was slope of the line. The surface tension(γ) of the ketones had more signifcant effect on thewickability compared to the viscosity(η) of them. The greater wickability resulted in the higher dye uptake on the fabricand the order of wickabilty was equal to that of the surface tension(γ) and dye uptake on the fabric, A>3P>2P>M.
