This paper introduces the concept of JetRing spinning, a new spinning technique that incorporates features of both ring and air-jet spinning systems. In JetRing spinning, a single air jet is used below the yarn-forming zone of a conventional ring spinning system; this jet acts in a way similar to the first jet in air-jet spinning. The swirling air currents in the jet wind the protruding fibers around the yarn body, thus reducing yarn hairiness. The air pressure applied to the jet in this study is 0.5 bar, which is much lower than the air pressure used in air-jet spinning. To evaluate the performance of JetRing spinning, ring spun and JetRing spun worsted yarns of 56 tex are tested for hairiness, tensile properties, and yarn evenness. The hairiness results from the Zweigle hairiness meter show that the JetRing spun yarn has much lower numbers of hairs than the ring spun yarn in almost all the hair length groups. The total number of hairs exceeding 3 mm (i.e., the S3 value) for the JetRing spun yarn is nearly 40% less than that of the ring spun yarn, while both yarn types show little difference in evenness and tensile properties.
