Investigation of intermingling process that applied in texturing and effective factors on intermingling

In this thesis, POY filaments which have two different linear densities (122, 283 dtex) and two different filament numbers (68, 100) in cross section were used as raw material. POY bobbins were intermingled with Hemaks brand, HMX 114 model intermingling machine. Production was made by selecting three different speed levels (150, 300, 450 m/min) and three different pressure levels (3, 5, 6 bar). Intermingled yarn quality characteristics (number of nips, unevenness of nips, stability of nips, yarn strength and elongation) have been tested and these features were evaluated as response (dependent) variables. Linear densities of POY, 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 software package and so effects of selected independent variables on the response variables were evaluated as statistically and results were interpreted.
