摘要
The effect of oxygen (PO), nitrogen (PN) and nitrogen/hydrogen gas mixture (PM) low temperature plasma (LTP) treatment on thermomechanical properties of fully oriented yarn (FOY) and partially oriented yarn (POY) of polyester was studied. The POY was drawn with six different combinations of draw ratios (1.5, 1.8 and 2.0) and draw temperatures (150 °C and 180 °C). Crystallinity, glass transition temperature (Tg) and maximum shrinkage were studied by thermomechanical analyzer (TMA) and differential scanning calorimetry (DSC) in order to identify the effect of LTP on thermomechanical properties of polyester yarns. Crystallinity percentage, Tg and maximum shrinkage were altered differently with LTP treatment.
