Comparison of a New Tribological Method for the Evaluation of the State of a Fabric Surface with the KES-F Surface Tester

摘要

Several processes in textile finishing involve a change in the state of the fabric surface, for example, sanding, raising, calendering, washing, enzyme treatments, and fulling. There is no current control system for these processes. A new tribological method for quantifying the modification of the state of the fabric surface is described. It involves the use of a rotating tribometer with signal-processing in a frequency domain. Analysis of the spectra of the signal obtained revealed that peaks were correlated with the structure and the density. In addition, the state of the fabric surface was determined by frequency spectra in which peak heights were dependent on the fabric roughness. The aim of the work reported in this paper was to compare this new method with the KES-F Surface Tester. It reveals that the multi-directional-tribometer method was superior to the KES-F Surface Tester for the characterisation of various finishing processes.
