项目摘要

1.A cylinder weight of 710g was 10 times repeatedly dropped on a set of alternately stacked up fabrics of five test cloths soiled with multi-components and five white cloths containing detergent solution. The detergency was calculated from K/S based on the reflectance of the test cloths and fabric bending and water stream were observed by high-speed video camera. The following results have been obtained :1) The content of detergent solution or water in a stacked fabric positively affects on detergency until 290%.2) The increase of falling distance with the weight raises the detergency of upper and middle stacked fabrics. The detergency does not simply relate to kinetic energy that is a function of the falling distance but also water content.3) Although the curvature of weight's base does not affect on detergency of the central and its periphery region in upper-position cloth after dropping with the weights, it brings the high detergency in lower-position cloth dropped with the weight of middle-curvature.4) It has been observed by high-speed camera that bending of fabrics by dropping with middle-curvature weight is large.5) Amount of water splashes calculated from water area in images relate to detergency in the region of central periphery of soiled cloth.6) The surface condition of the fabrics observed by microscope does not change before and after dropping repeatedly.2. In alternating flow system, it was shown the possibility of decreasing the amount of detergent as much as 50% air introducing to the wash liquor.3. In Lima it was inspected that people washed their heavy soiled and thick denim by beating with a stick.

1.将重量为710g的圆柱体反复下落10次，放置在5块被多组分污染的测试布和5块含有洗涤剂溶液的白色布交替堆叠的织物上。根据测试布的反射率，通过K/S计算去污力，并通过高速摄像机观察织物弯曲和水流。结果表明：1)洗涤液或水的含量对织物去污力的正向影响达到290%。2)下落距离随重量的增加，提高了上、中层叠布的去污力。去污力不仅与动能有关（动能是下落距离的函数），还与含水量有关。3)重物底座的曲率对重物下落后上层布中心及其周边区域的去污力没有影响，但对中曲率重物下落后下层布的去污力有较高的影响。4)通过高速摄像机观察到，中曲率重量的织物的跌落弯曲较大。5)从图像中水体面积计算出的水花数量与污布中心周边区域的去污力有关。6)显微镜观察织物的表面状况在反复滴下前后没有变化。在交变流系统中，表明有可能减少洗涤剂的量，最多可减少50%的空气引入洗涤液。在利马，检查发现人们用棍子敲打洗又脏又厚的牛仔布。
