The relative acid and alkali stabilities of various nitrogenous finishes for cotton have been compared. The effect the groups attached to the carbonyl and the substituents on the amido nitrogen exert on the electron density of the amido group has been related to acid and alkali resistance.
The finishes studied included those derived from urea. cyclic ureas, carbamates, and carhoxylic amides. In general, the groups exerting strong electron-attracting force on the amido group will increase the acid stability of the resulting finish and decrease the alkali resistance, and the groups which are strong electron donors increase the alkali stability and decrease the acid resistance.
