Vapor phase aminolysis of poly(ethylene terephthalate) (PET) fibers was studied as an alternative to aqueous phase aminolysis. Less effluent is generated during the vapor phase treatment. The effects of vapor phase aminolysis on the fine structure of PET fibers appears to be similar to those of the aqueous phase treatment. In both phases, molecular weight and tenacity decrease while density increases somewhat. Differences, however, are apparent and might indicate that aminolysis in the vapor phase is less selective than in the aqueous phase. In addition, longitudinal cracks formed on the fibers treated for long periods of time in the vapor phase whereas aqueous treatments generally result in radial surface cracking.
