PET fabric aminolyzed initially by ethylenediamine were reacted with various sugar-lactone in order to increase their hydrophilicity. The adsorption-desorption isotherm and amount of water vapor adsorption on the fabrics were investigated concerning with aminolysis time of initial treatment and reaction times with sugar-lactones. Effects of the unit number and difference of sugar-lactones were discussed on the basis of water vapor adsorption results. Mechanical strength of PET fabrics treated here was also investigated by relating to the reaction times.
