【 摘 要 】

The purpose of this work is to find out the influence of thread type, extension ratio and number of cycles to decrease in strength due to stress. In this study four different ratio of spun polyester and polyamide threads are used to sew the textile material (used for car seat cover) by a lockstitch sewing machine. The measuring system simulation of cyclic load has been used. The tensile load, which corresponding to 20 %, 30 %, 40 %, and 50 % of the breaking extension of seam, acting on the experimental specimens with different type of was calculated. Based on the results of experimental measurements, which were closer to the real using conditions of seat covers, it can be stated that with increasing number of cycles, the strength due to the influence of the stress were decreased.
