カバード糸製造における張力装置の効果について Effect of Tension Device on Covering Process of Spandex 90019761 Shintaku, Sukenori Iwaki, Nobuo 90195321 Kinari, Toshiyasu 90019761 新宅, 救徳 岩木, 信男 90195321 喜成, 年康 Spandex can be extended over eight times by a light load compared with a conventional yarn, and then it has the excellent properties for clothing than rubber. But we should pay particular attentions for the tension control in weaving, knitting and winding processes, therefore spandex is often used in a covered yarn with a different kind of fiber called a covering yarn. The tension of spandex has to be kept a constant level in the covering process. It affects the elongation of the covered yarn, therefore the tension irregularity causes the elongation irregularity of the covered yarn. In this paper, the covered yarn was produced by using the non frictional positive tension device controlled by the tension feedback. The covered yarn in this method has better points under the same condition of covering. (1) The pitch irregularity of the covering yarn is removed and the load-elongation curve is completed at any samples. (2) The deviations of the breaking elongation and strength are reduced and the breaking strength is enlarged. 1983-03-30 金沢大学工学部 = Faculty of Technology Kanazawa University 1983-03-30 2017-10-03 jpn departmental bulletin paper VoR https://doi.org/10.24517/00011695 http://hdl.handle.net/2297/25251 https://kanazawa-u.repo.nii.ac.jp/records/11708 10.24517/00011695 http://ci.nii.ac.jp/naid/40000512643/ AN00044309 0022-832X 金沢大学工学部紀要 = Memoirs of the Faculty of Technology Kanazawa University 16 1 93 101 https://kanazawa-u.repo.nii.ac.jp/record/11708/files/AN00044309-16-1-93-101.pdf application/pdf 276.4 kB 2017-10-03
