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710 g的圆筒重量重复地落在一组交替堆叠的织物上10次，所述织物由五块被多组分污染的测试布和五块含有洗涤剂溶液的白色布组成。根据测试织物的反射率，由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）叠层织物中洗涤剂溶液或水的含量在290%以下对洗涤效果有正影响;（2）随着重量的增加，下落距离的增加，上、中叠层织物的洗涤效果提高。3）虽然重物底部的曲率对重物下落后上部布中心及其周边区域的去污力没有影响，但重物底部的曲率对重物下落后上部布中心及其周边区域的去污力没有影响，4）通过高分辨力扫描电镜观察发现，在低位置织物上，随着中曲率的重量下降，织物的去污力也随之提高。5）根据图像中的水面积计算出的飞溅水量与脏布中心周边区域的去污力有关6）通过显微镜观察到的织物表面状况在反复跌落前后没有变化.在交变流系统中，可以将洗涤剂的引入量减少50%.在利马，人们发现，人们用棍子抽打厚重的脏牛仔布。
