This research has the objective of reducing the amount of detergent in comparison with that by a commercial washing machine. The following two kinds of experiments were carried out :10 to 30 sheets of fabric swatches well soaked in wash liquid were piled into layers on a horizontal iron plate. Arod of stainless steel (φ26mm, 710g weights) was dropped, with its end cross section downward, on the piled fabrics from the height of 30 cm. (1) The artificially soiled cotton fabrics was cleaned with the state that it became more white in the area of ring-shape which approximately corresponds to the edge of the flat bottom of the rod contacting with fabrics. That is, the washing performance of periphery of the contact area is higher than the inside. This suggests the importance of flow induced by the falling rod. (2) Difference in material of fabrics (cotton or polyester) did not affect on the removal of the soil. In conclusion, this impact pressure method is good for washing.2. Experiment on the washing method utilizing pulsating flows.This method consists in pulsating flows through the fabric placed between two gauges in a cylinder in order to import beneficial mechanical effects to sheets of soiled fabric such as deformation clash of the fabric against the gauges and penetration of a liquid flow through the fabric. (1) Detergency was shown by this method to be almost two times higher than that possible by a commercial washing machine. (2) By mixing air bubbles into the liquid with the ratio of 20% in volume, the performance of detergency does not decrease, which means reduction of detergent by about 20%.

这项研究的目的是与商用洗衣机相比，减少洗涤剂的用量。进行了以下两种实验：将10 ~ 30片织物样品在洗涤液中充分浸透，分层堆放在水平铁板上。将直径φ26mm、重量710g的不锈钢杆，端部横截面朝下，从30cm高度落在堆积织物上。(1)对人工弄脏的棉织物进行清洗，使其在近似于与织物接触的杆的平底边缘的环状区域变白。即接触区域外围的洗涤性能高于内部。这表明了由降杆引起的流动的重要性。(2)织物材质的不同（棉或涤纶）对土壤的去除没有影响。综上所述，这种冲击压力法对洗涤效果较好。脉动流洗涤方法的试验研究。这种方法包括通过放置在两个量规之间的织物的脉动流，以便将有益的机械效应引入到脏织物片上，例如织物与量规的变形碰撞和液体流过织物的渗透。这种方法的去污力几乎是商用洗衣机的两倍。(2)将气泡以体积20%的比例混入液体中，去污剂性能不下降，即减少去污剂20%左右。
