The effect of the production paremeters of intermingling and filament properties on the stability of yarn nips [Puntalama isleminde üretim parametrelerinin ve filament özelliklerinin punta kaliciligina etkisi]

The aim of this study is to evaluate many parameters on the intermingling process and to determine statistically the effects of these parameters on the stability of yarn nips. for this purpose,poy (partially oriented yarn) 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 by selecting three different speed levels (150,300,450 m/min) and three different pressure levels (3,5,6 bar). stability of the nips of intermingled yarns has been tested and this feature was evaluated as response (dependent) variable. linear densities of poy,number of filaments in crosssection,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 the effects of selected independent variables on the response variables were evaluated statistically and results were interpreted.
