    This study aims to make clear the soap deposition on cotton and polyester fabrics in washing and rinsing process under the condition of home laundering with powdered soap containing sodium carbonate. The main results obtained are summarized as follows:
    1. When polyester and cotton fabrics were laundered together in the same laundering bath with powdered soap, the amount of metal soap deposited on polyester fabrics became larger than that in the case of laundering each fabric separately.
    2. These phenomena were concerned with the fact that Na-soap absorbed on cotton fabrics in laundering process was converted into metal soap in rinsing process and that these metal soaps from cotton redeposited on polyester fabrics in the rinsing process.
    3. It was found that the amount of metal soap deposited on cotton or polyester fabrics lowered as the concentration of powdered soap in washing solution increased when the hardness of water used kept constant.
    4. These phenomena could be explained in terms of the dispersing ability of metal soap due to the Na-soap.

    The influence of energy given by the liquid flow on the efficiency of detergency has been studied in several washing methods.
    The efficiency of detergency of the home laundering machine with a pulsator is constant irrespective of the velocity of the liquid flow and the laundering time, if the dynamic energy of the liquid flow calculated by the theoretical equation is constnat.
    The electro-kinetic washing the Terg-O-Tometer washing and the repeated shearing stress washing have given similar result to the above conclusion, i. e., the efficiency of detergency estimated from other published studies is mainly determined by the dynamic energy of the liquid flow irrespective of the velocity of the liquid flow and the laundering time.
