Increasing the wear resistance of the traveller remains an immense challenge due to the high mechanical and thermal stress experienced by travellers during the spinning operation. Due to this exposure, surface deformation, such as scratches and coating deformations, are unavoidable. In this study, two kinds of travellers (Cr coated and uncoated) were examined according to their scanning electron microscopy images, for surface characteristics, and energy-dispersive X-ray analysis, used for the elemental analysis or chemical characterization of traveller surfaces. In addition, the hairiness of the yarns produced using the sample travellers was measured in order to see the effects of the traveller coating on the yarn properties. For the test, two kinds of travellers, with different surface treatments, were used for the same spinning machine. Only one sample type was Cr coated. The results revealed that the surface treatment of the travellers had a significant effect on the hairiness of the yarn.
