Frictional Behavior of Synthetic Yarns During Processing

Abstract

The frictional behavior of synthetic yams during various textile processes is investi gated in this paper. The main advance of this work over previous research is that the deformation of the oil film lubricating the fibers is taken into consideration. The thickness of the oil film decreases due to pressure, which causes changes in the friction mechanism. To account for the transition, the effective hydrodynamic friction length during the process is defined, calculated, and discussed in this paper. The theoretical results can be used to validate and explain the findings from existing experiments made available by other researchers.
