Abstract: In this paper, with the purpose of recovering wrapped and core-spun composite yarns’ defects, the design thought of novel composite yarn was analyzed using TRIZ Nine Screen Method. Furthermore, technology conflict resolution principles 1, 15, 17, 27 and 32 were applied to direct and complete the design and manufacture of novel composite yarn: three filaments were fed into the front nip and located into drafted strand at a certain distance by a special input feed system, and they were twisted into such novel composite yarn by spindle after the filaments and cotton fibers were exported through the front roller nip. Finally, the real structure of designed yarn was very similar to ideal structure which came from TRIZ theory, and the novel composite yarn, compared to core-spun yarn and wrapped yarn, had innovative structure, excellent strength and abrasion resistance, at the same time, the hairiness property was also improved greatly.
