Compression performance is a major factor in determining the life wear of each carpet. The toughness of the pile surface, as one of the compression properties of carpets, changes when exposed to wear in use. The main aim of this study was to predict the toughness characteristics of the surface piles of hand-knotted carpets at different levels of traffic exposure. Two types of hand-knotted carpet samples with symmetric and asymmetric knots and similar structural specifications were produced. A Hexapod tumbler tester was used to impose controlled worn out at different traffic exposures (drum revolutions). The samples were then tested with a tensile tester in the compression mode, and load-crush curves were obtained. The compression toughness characteristics and loss rate of toughness of the carpet samples were determined at 0 (new carpet), 4000, 8000, 12000 and 16000 revolutions of the Hexapod tumbler tester. Regression analysis was used to find the correlation between the traffic exposure (drum revolutions) and compression toughness characteristics. The results showed that knot type affects the toughness characteristics of the carpet. However, this effect is not statistically significant at the 5% level. On the other hand, different traffic exposure significantly affects the toughness characteristics at the 5% level.
Właściwości podczas ściskania są podstawowym czynnikiem określającym żywotność każdego dywanu. Odporność na ściskanie okrywy dywanu, jako jedna z podstawowych właściwości ściskania dywanu zmienia się z ich ekspozycją na zużycie. Głównym celem pracy było przewidywanie odporności na ściskanie okrywy ręcznie wiązanych dywanów przy różnym natężeniu ich użytkowania. Badano dywany o dwóch strukturach węzła – symetrycznej (tureckiej) i asymetrycznej (perskiej). Zastosowano specjalny przyrząd zgodny z ISO, symulujący obciążenie dywanów krokami. Sprawdzono charakterystykę dywanów po 0, 4000, 8000, 12000 i 16000 obrotów elementu obciążającego. Analiza regresji posłużyła do określenia korelacji pomiędzy ilością obciążenia a odpornością na zgniatanie. Stwierdzono, że charakter wiązania ma pewien niewielki wpływ na odporność dywanów na zgniatanie.
