Abstract :Polypropylene fiber was used as the pile yarn in the construction of three-dimensional woven carpet structures. The properties of the developed polypropylene carpets were investigated under both flexure and compression loading conditions. The flexure rigidity and curvature of dry and wet polypropylene pile fiber carpets were found to be influenced by factors such as pile height and pile density, with indirect effects observed on weft density. Furthermore, it was identified that the average dry bending rigidity of the carpet exceeded the average wet bending rigidity by a factor of 2.06 in the case of the apparel fabric test and 6.10 in the case of the technical fabric test. The thickness loss (%) in different polypropylene carpets exhibited a proportional relationship with the pile density. The thickness experienced a decrease with increasing pile density, primarily due to the enhanced compression load carrying capacity of each polypropylene fiber knot. This effect was more pronounced in carpets with denser knots compared to those with sparser knots per unit area. Finding from the study can be useful for the polypropylene carpet designers in particular complex curvature part manufacturing.Keywords : 3B halı, Polipropilen lif, Eğilme, Statik yükleme, Hav yoğunluğu.
