The physical shape or geometry of the spinning triangle directly affects the quality of ring spun yarns. This study developed a technique to measure the geometrical parameters of the spinning triangle during ring spinning using a combination of a clear rubber roller and digital image processing. The clear roller exposed the spinning triangle zone during the yarn spinning process in a non-invasive manner, and yarn properties were not affected. A digital camera recorded images of the spinning triangle. An image processing algorithm was then developed to process the images to measure the dynamic geometry of the spinning triangle. The method was able to effectively measure the width, height and skew of the spinning triangle along with changes in these parameters over time. This technique will be applied in a follow-up study to investigate the effects of the shape of the spinning triangle on yarn quality.
