Comparative dyeing studies of reactive dyes and conventional direct and acid dyes on silk

Remazol reactive dyes after alkali fixing caused no reduction in tensile strength. Higher depths of shade in acid dyeing of reactives were observed than in conventional dyeing. Exhaustion percentages were on average, acid dyes 98, direct dyes 85, and reactive dyes 70-50. Fastness properties in all cases have been carefully checked and are in all cases satisfactory
