Abstract

The reactivity-hydrolysis relationship in chemical finishing of cotton with N-methyloltype reactants under acidic conditions has been discussed. Theoretical and practical justifications for the relationship have been presented to demonstrate that the ease of formation of links is related directly to the ease of hydrolysis of links, and relative rates in both directions are predictable, based on steric and electronic effects on the resonance-stabilized intermediate. Bond cleavage during hydrolysis has been shown to occur first at the carbon-oxygen bond of the methylol groups, whether or not the link was formed from a substituted urea-formaldehyde adduct or a substituted urea-glyoxal adduct. Limitations for the relationship are also discussed.
