In this study, we describe a technique to produce a new composite yarn with different cross-sectional and longitudinal appearances on a modified ring spinning machine. These new composite yarns are produced by adjusting the delivery speed ratio between staple fiber and filament. In order to examine the effect of the delivery speed on the yarn structure, we investigated the convergence points in the yarn formation zone, with various delivery speeds, using a high speed camera. The convergence point migrated from side to side depending on the delivery speed and, as a result, the produced yarn had various structures. We also evaluated the properties of composite yarns depending on the delivery speed ratios of the filament and staple fiber as well as the twist multiplier in the new composite spinning system. The delivery speed ratio changed the yarn properties, such as unevenness, imperfections, tenacity, elongation, and hairiness. The twist multiplier had a minor effect on the yarn properties for the same delivery speed ratio.
