This study aims to develop a composite yarn comprising monofilaments/staple fibers with distinctive structures and performance. A modified ring spinning system was proposed for producing the composite yarn with three monofilaments and staple fibers. The spinning mechanism was analytically modeled, and the structures of composite yarn were studied by scanning electron microscopy and optical microscopy. The characteristics of polyester monofilaments/cotton composite yarns and the conventional cotton yarns were compared. Analytical and experimental results showed that three monofilaments were distributed around the yarn center forming a 3D spiral, and the staple fibers interlaced inside and wrapped outside of the composite yarn. Experimental results showed that the composite yarn had better tensile properties, less hairiness, and stronger abrasion resistance. As a result, the composite yarn exhibited a remarkable improvement over the conventional yarn, which could be a valuable proposition for specific purposes, such as offering fabrics with shape preservation based on good yarn’s rigidity, and even electromagnetic shielding effectiveness with metal monofilaments in yarns.
