Studies have been made to improve dyeing properties of cotton by introducing amino groups. The hydrolysis of an aminating agent, 2-amino-4, 6-dichloro-s-triazine(ADC), and the most suitable conditions for its treatment in an acetone -watermixture in the presence of sodium carbonate have been estaablished. It was noted that the hydrolysis of ADC was accelerated by the hydrogen chloride formed in the reaction. The hydrolysis in a sodium carbonate solution agreed with a second order reaction and the activation energy was calculated to be 19.5kcal/mol. When cotton was treated with ADC under the conditions of ADC 0.08 mol/l, sodium carbonate 0.16 mol/l, bath ratio 1:50, at 20°C for 24hr, aminized cottoncontaining 0.43% nitrogen was obtained . It was found that the cotton so treatedcould be dyed with acid dyes and its wash-fastness improved.
