The effect of fluid force on detergency has been experimentally investigated. It was conducted on the flow of aqueous solutions of detergent through mesh screens to mimic cloth washing. Pressure losses across the mesh screens were measured for water, dilute polymer and several aqueous surfactant solutions. A reduction of pressure losses was observed for the flow of aqueous solutions of surfactants, but not for the dilute solutions of polymers, through mesh screens. On the other way, viscosity of solutions was measured. For all solutions used, the viscosity increase with an increase of concentration. And it decreases with an increase of temperature. So the results of viscosity are different from those of drag.These mean that aqueous solutions of surfactants provide an effect to reduce the drag of flow through yarns or fibers and to increase the flow rate, resulting in easier removal of soil than in water, as well as the effect to lesson the chemical potential between soil and substrate.

已经通过实验研究了流体力对去污力的影响。它是通过洗涤剂水溶液流过筛网来模拟布料洗涤的。测量了水、稀聚合物和几种表面活性剂水溶液穿过网筛的压力损失。观察到表面活性剂水溶液流过筛网时压力损失减少，但聚合物稀溶液流过筛网时压力损失没有减少。另一方面，测量溶液的粘度。对于所有使用的溶液，粘度随着浓度的增加而增加。并且随着温度的升高而降低。因此，粘度的结果与阻力的结果不同。这意味着表面活性剂的水溶液提供了减少流过纱线或纤维的阻力并增加流速的效果，从而比在水中更容易去除污垢，如下所示以及降低土壤和基质之间化学势的作用。
