The characterization of surfaces of technical ceramics used in the synthetic fibres industry by microscopy

Abstract

SUMMARYIn the manufacture of synthetic fibres such as nylon and Terylene, ceramic surfaces are used to guide and control the threadlines. Successful operation is critically dependent on correct friction between the threadline and the surface it contacts; this is achieved by control of surface topography. Microscopy, particularly the SEM, has played an important role in understanding the characteristics of different surfaces, control of manufacture of the surfaces, development of new surfaces and processes, and the elucidation of plant problems. Examples of these applications are illustrated and discussed.
