In this work, the open end splicer parameters as the compressed air (pressure, P and durations of tearing, Dt), the fibres feeding during splicing operation (1S10 and EII), and the recalling yarn codes (RI, RII and RIII) were investigated. In order to evaluate the contribution of the splicing conditions on the open end splice physico-mechanical behavior, we used the experimental Tagauchi design method. This kind of experimental design allows us, using simplification method, to reduce the amount of the experiments. To evaluate the splice appearance, the subjective (the experts notes) method and the objective (referring to a developed Thickness index value) one are compared. In our experimental field of interest, the results show that the feeding fibres parameter level increase gives the lowest Thickness index value which means good splice appearance. However, the compressed air remains the most important parameter because it represents the influential one on both the strength and the longitudinal characteristics of the spliced open-end spun-yarns (length of splice and the expert judgments).
