Abstract

This chapter presents that in the context of friction and surface characteristics, revolutionary developments have been made through utilization of the friction phenomenon for creating special adhesion effects and through modification of surface texture for achieving special thermal and moisture transfer characteristics. The chapter provides an overview on many of those developments. The chapter discusses friction and surface characteristics of synthetic fibers. It highlights the key design parameters that can assist in modifying the surface characteristics and the frictional behavior of fibers. Those parameters, which could be changed during the spinning process of most fibers, included: surface area, fiber cross section, fiber crimp, fiber orientation, and surface roughness. In addition, the impressive development in nanotechnology has made it possible to alter fiber surface at the nano level without influencing key physical characteristics of fiber. The chapter also highlights friction in wet media by discussing the effect of wetting on fiber friction and that of surface texture on the extent of wettability of fibers.
