| Popis: | The sorption of the sodium soaps of lauric, myristic, palmitic, stearic, and oleic acids from aqueous solutions by various textile fibers has been measured. The sorption of both the fatty acid and alkali components of the soaps by dull acetate rayon and dull nylon fibers was essentially the same as that shown by the corresponding bright (undelustered) fibers, while dull viscose rayon sorbed considerably more fatty acid than the bright fiber. In general, the order of increasing sorption was: cotton, nylon, acetate, bright viscose, dull viscose, and wool. Of the saturated soaps, the maximum sorption of fatty acid by all fibers was obtained with sodium myristate, while the alkali sorptions were approximately the same for myristate, palmitate, and stearate, all of which were higher than for laurate. The sorption from sodium oleate solutions corresponded approximately to that from the C14–C16 saturated soaps. Preferential sorption of alkali by cotton and viscose rayon was observed for all soaps, while acetate rayon, nylon, and wool showed preferential sorption of fatty acid with the lower molecular weight soaps and preferential sorption of alkali with the higher soaps. Suppression of hydrolysis by the addition of excess free alkali resulted in a reduction in fatty acid sorption in every case, and shifted the maximum from the C14 to the C16 soap. It is concluded that the sorption of soap by textile fibers is a complex process involving the more or less independent sorption of neutral soap, hydrolytic fatty acid (or acid soap), and hydrolytic alkali. |
