In order to examine the detergency, we made a washing experiment in the following way. First, using four kinds of fabric such as cotton, silk, wool and polyester, we made two kinds of artificially stained cloth : one which was stained with volcanic ash and the other stained with oil and volcanic ash. And we washed them by using powder soap and the synthetic detergent that were both on the market. Finally the detergency was decided by the measurement of the surface reflectivity and the observation of the scanning electron microscope. The following results were gained. 1. The detergent efficiency of cotton was very high on both the cloth stained with ash and the one with oil and ash. Next the cloth of polyester was high in the detergent efficiency. On each cloth of silk and wool, the efficiency was very low. 2. With the respect to the detergent, the detergent efficiency of the synthetic detergent was much higher than that of powder soap on each of the stained cloth. 3. When we washed each cloth of silk and wool with powder soap, we got a very low detergent efficiency. On the cloth stained with ash, we received a good correlation between the result of observation of the scanning electron microscope and the detergent efficiency. But a lot of stains were observed after we washed it.
