It was investigated that the laundry method of saving the consumption of detergent and water and damage of fabrics with effective detergency.1. Optimum mount of detergent and conditions for washing and a polyelectrolyte.(1) Each four kinds of commercial home laundry detergents made in Japan and Switzerland showed the same tendency for the relation between the effectiveness of detergency mad the amount of detergent supplied in washing liquor. The optimum conditions for detergency were obtained at the concentration of detergent more than 3 g/L and at the temperature of 40℃ with each detergents by Terg-O-Tometer.(2) Poly sodium α-hydroxyacrylate enhanced the detergency with mixing anionic surfactant, and also without surfactant showed the effectiveness more than 0.8g/L. The desolved oxygen consumption with microorganisms depended on molecular weight of the polymer.2. The dram-type home washing machineIn the drum-type home washing machine the less amount of detergent for optimum washing was obtained on the basis of fabric weight (9.2g/kg dry laundry) than liquor concentration (1.5g/L), however it needed the more water consumption. The fabric damage with the drum-type washing machine was less than the spin- or agitator-type machine usually used in Japan.3. The appropriate load ratio of washing to the amount of water in the bathThe maximum laundry performance was attained by the ratio of 1:8 on the basis of the surface area of the washing load (mィイD12ィエD1) to the amount of water (L) with both heavy and light fabrics density. The load ratio by washing weight (kg) to the amount of water (L) were different with heavy and light fabrics for optimum detergency.

探讨了一种既能节约洗涤剂和用水量，又能有效洗涤织物破损的洗涤方法。最佳洗涤剂用量、洗涤条件和聚电解质。(1)日本和瑞士生产的四种商用家用洗衣粉洗涤剂的洗涤效果与洗涤液中洗涤剂用量的关系呈现出相同的趋势。结果表明，在洗涤剂浓度大于3g/L、温度为40℃的条件下，α-羟基丙烯酸钠与阴离子表面活性剂复配时的去污效果可达0.8g/L以上。DRAM型家用洗衣机在滚筒式家用洗衣机中，根据织物重量(9.2g/kg干洗衣物)比以溶液浓度(1.5g/L)来获得最佳洗涤的洗涤剂用量较少，但需要较多的用水量。滚筒式洗衣机对织物的损伤比日本常用的旋转式或搅拌式洗衣机要小。适当的洗涤负荷与浴缸中的水量的比率在重密度和轻织物密度下，以洗涤负荷的表面积(mィイD12ィエd1)和水量(L)为基础，当洗涤负荷的表面积为1：8时，洗涤性能最好。对于厚型和轻质织物，洗涤重量(Kg)与水量(L)的负荷比不同，洗涤效果最佳。
