Rubbing pressure

Here, N, C, lo, and v are the number of times a location is rubbed, the diameter of the cylinder, the rotational speed of the cylinder, and the movement speed of the substrate stage, respectively. This equation is almost the same as Uchida s except that it does not include the contact length 1. Since the rubbing pressure is constant, the rubbing density does not include this parameter. In these equations, the rubbing strength is proportional to the number of times a substrate is rubbed. 

The buffing length of a single fibre I can be expressed by the rubbing pressure M, and the cylinder diameter r as,... 

From this equation, the ratio of the area, affected by rubbing, A is proportional to Wfl and increases with increase in rubbing pressure, and... 

Here, F(M) is the rubbing stress related to the rubbing pressure. Increasing the number of rubbings increases A, the ratio of the area affected by rubbing, but it...

Mechanical scrubbing (cleaning) Rubbing a surface with a cloth or sponge, usually wet or under a liquid. The scrubbing action displaces contamination from the surface but care must be taken that the scrubbing action does not result in abrasive transfer. To avoid abrasive transfer the rubbing pressure should be controlled. See also Abrasive transfer.
