INERTIAL COATING OF A FIBER

Fibres can be coated by passing them through a solution. At low veloci ty, the thickness of the entrained film is given by the Landau law. Fo r liquids of low viscosity, we discuss the high-speed withdrawal regim es which are of technological interest. We focus on inertial effects a nd geometrical limitations. New experimental data are presented and di scussed by using dimensional arguments. Finally, a classification is p roposed.
