Abstract:
Further work on carpet appearance change is reported, focusing on new textural measurements of carpet pile. These techniques have included image analysis, goniophotometry, and densitometry. A set of specially prepared saxony-type polyester carpet constructions were tested, both as unworn controls and service-worn to 60,000 steps of foot traffic. In Part II of this series, the results of goniophotometry, i.e. variable angle reflectometry, are reported. Techniques are presented to generate goniophotometric reflectance curves, which can be analyzed for directional pile lay in carpet. These techniques appear promising in characterizing certain changes in pile shading and wear patterns, both in unworn and service-worn carpet.
