Properties of Yarns Obtained by Combining FDY with POY, CDPET and Micro POY Polyester Filaments Under Different Texturing Conditions and Their Visual Effects in Knitted Fabric

In recent years, combination of filament yarns in continuous yarn production are used for innovative product development studies. In this study, POY and FDY polyester filaments having different structures and specifications were combined using nip-twisters by false-twist texturing method. Twelve different yarns were obtained by using constant FDY and three different POY materials with the state of FDY in first heater and two different drawing values. Linear density, breaking force, breaking elongation, shrinkage in boiling water and number of nips were measured in these yarns. Furthermore, the visual effects in knitting fabrics produced from texturized yarns were investigated. It was observed that the produced combined yarns have different structural and visual effects compared to single textured yarn
