The pile carpets are one of the main industrial products utilized for floor covering in homes, offices etc. Durability and sustained properties are very important factors for both customers and produces. The carpets withstand different degradation and deteriorations during the life time. UV radiation and traffic exposure i.e. wear are two parameters affect mainly the properties and performance of the pile carpets. The compressive properties of the carpets is an important parameter attracted many researchers. The main aim of this study is to investigate the effect of UV radiation and wear on the recovery properties of the pile carpets after removal of the static loading. Mechanical models composed of springs and dashpots are analyzed to explain the recovery properties and the non-recoverable deformation (thickness loss) of the carpet. The fibers, basically, consist of crystalline and amorphous regions. Different combination of springs and dashpots are usually used to model the different properties of textile materials. In this work four mechanical models are presented to analyze the recovery of the carpets after the removal of the static loading including Voigt-Kelvin, Linear Standard, Jeffery I and Jeffery II models. The carpet samples were first exposed to different levels of accelerated UVC radiation using a UV chamber. The samples were then exposed to different level of wear using a Hexapod tumbler tester. Static load was imposed to the samples for two hours; the static load was then removed leading to start of recovery. The thickness of the carpet, during the recovery, was measured in interval time of every two minutes. The plots of thickness loss versus the time were then obtained. The results showed that the recovery of the carpet is a time dependent process. The variation of Thickness loss-Time is steep at first; decreasing slowly and then tends to a constant value at higher recovery time. It means that some non-recoverable deformation exists after the removal of the static loading. The thickness loss increases with increasing the UV exposure time and the wear cycles. The statistical analysis revealed that the effect of UV exposure is more significant than the wear. The reason could be the degradation of molecular structure of the fibers by UV radiation. Analytical approach was used to analyze four presented models. Considering the governing differential equations of each model as well as the necessary boundary conditions the recovery-time relations were derived. The theoretical equations of each model were fitted to experiential recovery data using the Least Square method. The results showed that both Jefferies’ models fitted well with experimental curve of the recovery after removal of the static loading. The non-recoverable deformation (thickness loss) phenomena of the carpet can be, acceptably, explained by the Jefferies’ models. The Voigt-Kelvin and Standards Linear models show completely recoverable behavior which is in contrary to the non-recoverable (permanent thickness loss) deformation of the pile carpets after removal of static loading.
