Abstract

Thermal behavior of poly(ethylene trephthalate) PET partially oriented and texturing yarn has been investigated. Yarns were produced in three different levels of each of selected parameters during melt spinning and false twist texturing. Yarns were analyzed by differential scanning calorimeter (DSC).DSC is the most widely used equipment of thermal techniques. DSC analysis could easily detect the change of winding speed since winding speed alters the molecular orientation of the fiber. Quenching air temperature and quenching air speed effects could not be detected clearly by DSC analysis. Texturing yarns and flat yarns could be differentiating via DSC thermograms.
