poly(ethylene terephthalate) fibers were aminolyzed with hydradine hydrade and ethylenediamine. the moisture regain of aminated fibers increased with increasing weight loss. it was suggested that the aminolysis reaction took place mainly in the amorphous regions. this leads to an increase of the accessibility of moisture. the mechanical properties of the aminated fibers were reported as a function of the weight loss by the aminolysis reaction; tenacity, stiffness, and wrinkle recovery were considered and discussed with regard to fine structures. general trends of decreasing tenacity, stiffness, and wrinkle recovery with increasing weight of loss were observed for fibers aminated by hydrazine hydrate and ethylenediamine. within this trend, there is difficulty for application of aminolysis that will not provide superior performance in the polyester fiber property such as tensile strength, stiffness, and wrinkle recovery.
