In the preceding paper, it was found that a combination of the aminolysis of PET fabric by ethylenediamine and the following reaction with sugar-lactone gave a large increase of the hydrophilicity of PET fabric, but the former reaction caused decrease in its mechanical strength readily. Here, the effects of a reaction temperature of aminolysis and the structure of amines on the mechanical strength and an amount of water vapor adsorbed on it were examined. As a result, aminolysis at lower temperature or by using higher bulky amines prevented large decreases in the mechanical strength. Furthermore, we reported on the aminoiysis of PET fabric by sugar-amine (GlcNH2) synthesized from gluconolactone and ethylenediamine.
