  Abstract

A novel structural composite yarn was fabricated by periodically forcing filaments with harmonic migrations to enhance the cooperativity between filaments and staple fibers. The geometrical principle of yarn structure variations caused by harmonic migrations of filaments was theoretically analyzed, then demonstrated the influences of filament셲 positions on different shapes of the composite spinning-triangle zone. Further, the novel structural composite yarn structure was compared to the seven models of composite yarns which were established with different filament셲 positions, showing a varied filament helical structure to capture and then lock internal and external staple fibers, distinguishing that other composite yarns in literature. Then, a synergetic eccentric device was employed to oscillate two filaments to conduct confirmatory tests. The online observations of the dynamic spinning-triangle zone were technically applied to evaluate the filaments harmonic migrations. Furthermore, the yarn structural variations were caused by various geometrical configurations. Experimental results exhibited that the novel structural composite yarn had relatively fewer hairiness, medium irregularity, and strength after comparisons with other composite yarns. Altogether, the cyclically harmonic migrations of filaments were promising as an efficient and novel method for control the configurations between filaments and staple fibers.
