Summary The adsorption of soap on cotton from solutions of pure sodium oleate has been investigated. The adsorbate has been shown to be an acid soap of the composition 1 NaO1: 1 HO1. The addition of free sodium hydroxide represses hydrolysis and reduces the adsorption. The acid soap may be removed from the fabric by repeated boiling distilled water rinses or the adsorptive capacity for fresh acid soap may be restored by converting the adsorbed material to lime soap by rinsing in hard water. The resulting lime soap is largely retained by the fiber and on repeated washes accumulates in substantial amounts.
