Carpets are considered as an essential product for home decoration. Mechanisms such as abrasion, crush, fiber loss, flattening and loss of resilience can lead to variation in the appearance of the design and color of the carpet. Wear is a physical destruction of fiber, yarn and carpet which is the consequence of rubbing process. UV exposure also leads to the destruction of the materials. UV radiation causes the degradation in some parts of the polymer molecules as well as the progressive destructions of the polymeric chains. The aim of this study is the investigation of UV radiation and abrasion effects on the compression performance of the carpet. The specimens were subjected to the accelerated UV radiation for a specific time. The abrasion experiments were carried out using a Hexapod tumbler machine. The thickness of the samples, after radiation and abrasion, was measured by a digital thickness gauge. The compression tests were then performed using a Zwick tensile tester and the force-compression curves were obtained.The results showed that increasing the duration of radiation and the number of cycles of abrasion led to increase in the percent thickness loss. The effect of wear on thickness loss is significantly more than the effect of UV radiation. Using the Sigma plot software, statistical models were developed and verified using Minitab software.Van Wyk’s mechanical models as well as Maxwell, Linear Standard and Non-Linear Standard models were analyzed. Curve fitting method based on the least square method was used to correlate the theoretical models with the experimental data. The results showed that the Van Wyk’s model showed acceptable correlation with the experimental data in compression mode. The Maxwell and Linear models, in compression mode, showed poor correlation with the experimental data; while The Non Linear model revealed more acceptable correlation with experimental data. In decompression mode, Maxwell, Linear Standard and Non Linear models revealed good compliance with the experimental data. In this study one cycle of the compression and decompression was applied. The samples showed full recovery, with time, after the removal of the compression. From this point of view, the Maxwell model is not able to explain the full recovery as it shows some non-recoverable or plastic deformation; while the Linear and Non Linear models can well explain the full recovery of the carpet after one cycle of compression and decompression. It can be concluded that Non-Linear Standard model is more acceptable and recommendable model to explain the compression, decompression and recovery behavior of the carpet under just one cycle of compression and decompression.
