Using hollow yarns can change and improve many qualities of fabrics including thermal, acoustic, or mechanical properties. Using technical yarns in commercial textile products has been studied extensively to bring them some sort of functionality. In this study, side-by-side 50%/50% hollow bicomponent yarns made from different raw materials were tested and evaluated to determine their processing behaviour and performance characteristics. All yarns have coPET as one component where the other component is PET, recycled PET (rPET) and PA6, respectively. The mechanical and physical properties were evaluated by various tests, including unevenness, crimp testing, hollow ratio, and shear test. Their thermal and thermomechanical properties were also evaluated with DSC analysis. Same evaluations were done on the non-textured and textured state of the yarns to see the effect of the heat treatment.
