But nowadays the quality of product is as important ashigh production rates and lower costs. The most important factors that affect thequality for texturing of polyester fiber are properties of raw-material and productionparameters. If the properties of raw-material are fixed; it is obvious that the physicalproperties of yarn and fabric will depend on the production parameters duringtexturing process.In this study; the effect of texturing variables on physical properties of yarnduring texturing process were examined. Each variable that is thought to affect theyarn properties were changed between controlled levels to investigate the change ofyarn properties according to production variables.Key Words: Texturing of Polyester, Texturing Parameters, POY, CrimpII
