Abstract: The molecular orientation of dye introduced into a fibre was characterised numerically by the coefficient of molecular orientation fD. Lowering its value was the result of decreasing molecular orientation in non-crystal areas of the grafted PET fibre.The fD index was influenced by the following grafting reaction parameters: time of modification reaction,temperature and concentration of acrylic acid in the bath.
