Poly (trimethyleneterephthalate) is a new polymer material. Using polaroid and horizontal ATR accessories combining FTIR spectrometer, the orientation of PPT fiber undergoing different drawing rate was studied. The dichroic ratio and orientation function were determined. The results show that both the dichroic ratio and the orientation function increased with drawing rate, but for dichroic ratio, there was a plateau when drawing rate was above 2,500 m.min-1.
