The aim of this study is to evaluate many parameters in intermingling process and to determine the effects of these parameters on yarn properties statistically. For this purpose, POY (partially oriented polyester yarn) filaments, which have 283 dtex linear density and four different filament numbers (34, 47, 68, 100) in cross-section, were used as raw material. Samples were produced at speeds of 150, 300, 450 m/min and pressures of 3, 5, 6 bar, respectively. Intermingled yarn’s strength, elongation, and the number of nips were tested and these features were evaluated as response (dependent) variables. Number of filaments in cross-section, intermingling speed, and intermingling pressure were taken as independent variables. General factorial design was applied by using Design Expert 6.0.1 and SPSS 15.0 software package, and therefore, the effects of selected independent variables on response variables were evaluated statistically. Results showed that the intermingling pressure and number of filaments have statistically significant effects on all the response variables. Moreover, it is observed that there is an interaction between pressure and the number of filaments. The intermingling speed on the other hand has no statistically significant effect.
