Investigation of Mechanical and Liquid Transmission Properties of Hydroentangled Nonwovens Containing Segmented Pie Bicomponent Fibers

The aim of this study is to investigate the performance properties (tensile strength, elongation, liquid strike through time, wetback and liquid absorption capacity) of hydroentangled nonwovens containing segmented pie bicomponent fibers. Within the scope of the study, different water jet pressures were used to investigate the effect of performance properties of nonwovens containing 8 segmented pie bicomponent (PET/PA) fibers on process variables such as water jet pressure. On the other hand, three different basis weights (30 g/m2, 45 g/m2, 60 g/m2) were produced on the same (apertured) pattern. The test results show that the water jet pressure affects the mechanical and liquid transmission properties of nonwovens containing 8 segmented pie bicomponent fibers. For products with the same basis weight and different water jet pressures, it was found that the tensile strength and elongation values increased as the water jet pressure increased. In addition, the liquid strike through time decreased as the jet pressure increased, while the liquid absorption capacity and wetback values increased. For the samples with the different basis weights, it was found that the liquid strike through time and liquid absorption capacity values decreased, and wetback values increased. In terms of mechanical properties, it was concluded that the tensile strength increased as the fiber content per unit area increased.
