the feasibility of incorporating amine groups into the surface of polyester (pet) fibers by reaction with multifunctional amines was investigated. reactions of diethylenetriamine (deta), triethylenetetramine (tetta), and tetraethylenepentamine (ttepa) with pet monofilaments and with a multifilament yarn were studied microspectrophotometric examination of aminated fibers stained with an acid dye at low ph revealed the location and concentration of amine groups. amination could be confined to the periphery and was found to be uniform on the fiber surface. scanning electron microscopy (sem) studies revealed that failure occurred within the filament most probably between the reacted and unreacted zones. the tensile properties of the ttepa-treated pet filaments were hardly affected at the investigated extents of amination.
