Investigation into the effects of yarn structure and yarn count on different types of core-spun yarns

The scope of this research is to study the effect of yarn structure and yarn count on properties of types of core-spun yarns, including elastic core/T400, elastic core/Lycra, dual core, and tri-core yarns. Five types of yarn structures and three yarn counts were produced. Mechanical properties, yarn irregularity, imperfections, and hairiness were measured. Full-factorial analysis and Tukey tests were performed on the test results. It was concluded from factorial analysis that yarn count, yarn structure, and two-way interaction had a significant effect on yarn properties, except for yarn hairiness where the effect of yarn structure and two-way interaction was not significant. A Tukey pairwise comparison was used in this study to specify exactly the subgroups of yarn count and yarn structure that have a significant mean difference. The scanning electron microscopy (SEM) images of the dual-core yarns and tri-core yarns were performed to illustrate the structure of these yarns.

Automated summary

This research studied the effects of yarn structure and yarn count on properties of different types of core-spun yarns. It found that yarn count, yarn structure, and their interaction significantly influenced yarn properties, except for yarn hairiness. Scanning electron microscopy images were used to illustrate the structure of dual-core yarns and tri-core yarns.
