Appearance and resilience characteristics of selected carpeting following serviceability testing

The purpose of this study was to investigate the differences in compressional resilience and the changes in appearance of selected carpeting following a serviceability test. Two types of investigation were used to collect the necessary data: (l) a laboratory test to determine the compressional resilience of the carpet samples, and (2) a subjective test to evaluate changes in appearance of the carpet samples by means of visual examination. A test carpet of six replicates of 12 selected carpets was used in the serviceability test. The 12 carpet samples were of tufted construction and included three fiber types (wool, acrylic and nylon), two pile types (cut and uncut) and two pile heights (high and low). Carpet thickness measurements (original, compressed and recovered) were taken to determine compressional resilience of the carpets. An analysis of variance for a 3 x 2 x 2 factorial design was performed on the measurements of compressional resilience prior to and following the serviceability test. The same statistical design was applied to the data obtained in the subjective evaluation of changes in surface appearance
