Abstract

Dynamic thread tensions during overlock machine sewing were measured and the influence on the stitch configurations and the seam characteristics such as stretchability and loose stitch was discussed. The results obtained were as follows;<BR>(1) Some peaks were observed on needle, right-hand looper and left-hand looper tensions during sewing (see Fig.2) . By changing the tension disc settings, some typical stitch configurations were obtained. The stitch forms were classified into two and four groups using explanatory variables such as the thread tension peaks and stitch length. It was possible to use the static thread tensions instead of the dynamic ones in classifying the stitch configurations.<BR>(2) Three thread length in seams were calculated by the multiple regression analysis using explanatory variables as mentioned above. The static thread tensions were also useful in predicting the thread length in seams.<BR>(3) Of all the three sewing thread consumption in seams, the shortest one is related to the breaking elongation of seams. The seam elongation can be predicted by using a linear relationship between the seam elongation and the shortest thread length.<BR>(4) The amount of seam grin was mainly determined by the needle thread consumption.
