The fatigue phenomena of the sewing threads on handsewing were experimentally investigated on the viewpoint of pulling out resistance of the sewing thread from the fabric. In this experiment, two kinds of fabrics were plain stitched with various numbers of stitches, using several sewing threads. The pulling out resistances of the sewing threads were measured at various pulling out angles by a Tensilon STM instrument.The results obtained are as follows: (1) In either case, immediately when the sewing thread begins to bc pulled out from the fabric, the maximum pulling out resistance is observed, and it decreases to levelling off resistance. (2) All of the pulling out resistances of silk, cotton, and Cotton handsewing threads are larger than that of polyester sewing thread. (3) At the pulling out angle of 90゜, the pulling out resistance is the largest. (4) The more the numbers of stitches, the larger the pulling out resistances. (5)The pulling out resistances of "Okamomen" are larger than those of "Sarashimomen" in all cases of the above results, (1)-(4). In our previous paper, the fatigues of pulling out threads from "Okamomen" were larger than those of "Sarashimomen." From these above results, it is considered to be suggested that the pulling out resistance influences on the fatigue of sewing thread.
