Study on Dyeing Properties of Turmeric Yellow on Nylon Fiber

Abstract:

In order to provide the theoretical basis for nylon fiber dyeing with turmeric yellow, the dyeing properties of turmeric yellow on nylon fiber were investigated. The appropriate dyeing condition of turmeric yellow on nylon fiber was pH=4, and the final temperature at 90°C~95°C. The dye uptake of turmeric yellow on nylon fiber was relatively high, and the building-up property of turmeric yellow on nylon fiber was good. The adsorption of turmeric yellow on nylon fiber accorded to Redlich-Peterson adsorption model proximally,and the adsorption model was validated by the simulation coefficients and normalized deviations. The dyeing process was endothermic with the dyeing heat ΔH⁰ =71.34kJ·mol^-1, and entropy change ΔS⁰ = 274J·mol^-1, In addition,the dyeing affinity -Δμ⁰ and saturation absorption capacity increased as the temperature increased.
