The aim of this work is to explore a new method for producing spun yarn on a modified ring
spinning system which is called “clusterspun yarn”. Here, we describe the effects of the
clustering of polyester multifilaments on the internal structure and properties of a composite
yarn. Cotton fibers and polyester multifilaments were spun into 19 Ne cluster and core-spun
yarns at five different twist levels. These yarns were then tested to compare their properties,
including tenacity, elongation, and evenness. Surface morphology and structural variations
of cluster and core-spun yarns were studied by scanning electron microscopy. Microtome
and image-processing methods have been used to study the structure and packing of fibers
in the cross-section of yarns. The results show that the special structure of a cluster-spun
yarn results in pronounced enhancement in the structural mechanics and yarn properties.
The statistical analysis results indicate that the tenacity and breaking elongation of cluster-
spun yarn is significantly more than that in core-spun yarn. The results show that the twist
factor at about 3.9(α e ) gives the optimum properties. In addition, lower twist is needed to
produce quality yarn in cluster-spun yarns as compared with normal core-spun yarns.
