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.}, pages = {93--101}, title = {カバード糸製造における張力装置の効果について}, volume = {16}, year = {1983} }
