縫い目の性能からみた"後袖つけ"の検討

抄録

Effects of loose sewing in reducing rip of rear arm hole in a set-in sleeve were studied. It was found that : 1. The overfeed method is higher in strength and lower in elongation compared with the natural-feed method. 2. The overfeed method is stronger to a frictional force than the natural-feed method in the case when sewed in the transverse and positive bias directions of test cloths, while the relation is reversed when sewed in the longitudinal direction. 3. The durability of the rear arm hole of a blouse sewed with the overfeed method was very excellent compared with that sewed with the natural-feed method. It is concluded that the rip is reduced with the overfeed method by sewing half-way from the upper end of the side line to the shoulder point.
