ABSTRACT:
When from about 0.4% to about 5% of tertiary amines ##EQU1## WHERE R is an alkyl radical of 8-25 carbon atoms, R' is an alkylene radical of 2 to 10 carbon atoms, R" and R"' are hydrogen, a phenyl, or an alkyl radical of 1 to 3 carbons, but where R" and R"' are not both hydrogen, and x, y, and z are each at least 1 (x+y) is not greater than 6, preferably 2, and (x+y+z) is not greater than 9, preferably 3, are coated on nylon fiber, or are added to the dyebath, improved dyefastness is achieved compared to an untreated dyed nylon fiber when this fiber is exposed to ozone.
