The purpose of this research is to provide accurate information of household washers and detergents for consumers, so that help the producers who make washing machine and detergent to get basic material and also help consumers to choose washing machine. Experiment was proceed with two type of washers to compare energy consumption, washing performance, rinsing effectiveness further, damage caused by entanglement of laundry and fabric was assessed. Detergent P and T were used to compare the performance related to differences of ingredients of detergent. Soiled fabrics of EMPA 108 set were used to evaluate performance of washing by different types of contamination. A summary of experimental results are : First, for the consumption of water, drum-type washer consumed 53% less than pulsator-type washer. On the other hand, the washing time was almost similar for both these machines, but pulsator-type washer showed shorter progress, implying that power saving was more efficient in this case. Second, the drum-type washer showed better performance for contamination with all types of detergent, but the pulsator-type washer showed better rinsing performance. Third, the drum-type washer performed less data of tangle level and fabric damage. Fourth, detergent "P" exhibited better washing performance than did detergent "T", regardless of the type of soil. And with no limit of detergent variety, water-soluble protein soil showed high removal rate, liposoluble soil especially pigment was hardly removed.

각종 세정제의 난용 및 과대 사용으로 인한 수질오염이 날로 심각해지고 있으며 이 때 수질오염의 원인은 주로 계면활성제에 의해 발생한다. 본 연구는 이미 다졸린으로부터 유도된 9종의 양쪽성계면활성제와 석유 화학물질로부터 제조하여 대량 사용하고 있는 sodium lauryl sulfate(SLS)에 대한 세정성을 비교하여 보다 우수한 계면활성제를 선정하고자 한다. 또한 세정성의 비교는 세정력의 측정과 세정에 관한 물리화학적 측면에서 그 원인을 규명하고자 한다. 1-(2-hydroxyethyl)-1-(3-sulfonatedropy)-2-undecyl-2-imidazolinum [IV]는 세정성 및 다른 기초적 물성이 우수하여 세정제에 응용할 경우 세정성이 우수한 계면활성제 일수록 오염 부착에 필요한 일이 적게 나타나 오염이 쉽게 제거될 수 있음을 증명하였으며 그로 인한 공업적 응용성에 기대가 크다.
