Principles of drying

The principle of dry scrubbing was first recognized by Lamb and Wilson [lirEC, 11(5), 420 (1919)] and Wilson [lirEC, 12(10), 1000 (1920)] at MIT during their World War I program to develop better...

The principle of dry spinning is shown in Figure 17.16. Dry spinning is not widely applied cellulose acetate fibers are dry-spun, and whereas acrylics and polyvinyl alcohol can be dry spun, wet spinning is preferred. 

In this section we discuss dry friction, also called solid or Coulomb friction. Dry friction occurs when two solid surfaces are in direct contact without any other components such as lubricants or adsorbed surface layers involved. One might object that in practice no such surface exists under ambient conditions and that all surfaces are somehow contaminated. However, the basic principles of dry friction may apply even in this situation.
