Abstract:

In this study, viscoelastic model parameters are obtained to predict the compression and recovery behaviour of needle-punched nonwoven textiles which are customarily used in industrial applications such as automotive floor-coverings. To this end, two different models are used to explain the compression and recovery behaviour of non-woven textiles under brief, moderate static loading (BMSL) and prolonged, heavy static loading (PHSL) according to ISO 3415 and ISO 3416, respectively. The first model consists of a linear spring and damper set parallel to each other. This combination is placed in series with a linear damper. The second model, however, consists of a linear spring and damper set parallel to each other and placed in series with a nonlinear damper. The results obtained for the compression and recovery behaviour of the non-woven textiles under BMSL and PHSL are compared with experimental results. The results obtained indicated that the nonlinear model is more accurate in the prediction of the compression and recovery behaviour of needle-punched nonwoven textiles under static loading than the linear model. The best result for the prediction of the compression and the recovery behaviour of nonwoven textiles under BMSL and PHSL occurs with the nonlinear model, in which the errors are 4.68% and 4.66%, respectively, when compared to the experimental results.
