Outline of Final Research Achievements

The false twisting machine produces false twisted yarns used in textile products. In the case of high-speed production, surging, which is an unstable vibration phenomenon of yarn, occurs in the false twisting machine. Surging significantly reduces the yarn quality. In this study, we developed a surging inspection system to be installed in the processing machine. This system enables to investigate the yarn morphology and yarn quality from the viewpoint of the 4T (twist, heating temperature, heating time, and yarn tension), which are the important processing elements of the processing machine, according to with or without surging.

Academic Significance and Societal Importance of the Research Achievements

本研究では繊維製品に用いられる加工糸を生産する仮撚加工機でのサージング現象を実験的に把握した．サージング現象を観察するために検査システムを開発し，ディスク構成およびサージング有無による糸形態について検証を行った．その結果，仮撚加工機において加撚張力がサージングの抑制および糸品質に起因することが明らかとなった．本成果は国内外において類がなく，仮撚加工機の性能向上にも寄与できたといえる．
