“…One can also see from Figure 1 that at pH 5.80 less dye is adsorbed at equilibrium at 80° than at 70,° as is to be expected for an exothermic heat of adsorption [24]. At low pH, the expected relation with temperature is evident for times less than 500 mien but for longer times the amount of dye adsorbed at the higher temperature exceeds that adsorbed at the lower temperature.…”

The effect of draw ratio on the diffusion kinetics of Orange-II in nylon 66 has been investigated in an infinite dyebath buffered at pH 5.8 at temperatures between 40° and 102° C. Diffusion coefficients were ohtained by applying Hill's equation to the total amount of dye adsorbed as a function of time. As the fiber is drawn, there is very little reduction in the equilibrium adsorption of dye, but the diffusion coefficient is reduced to about one-half its previous value for each integral unit of draw ratio. Activation energy for diffusion increases from about 22 to about 28 kcal/mole as the draw ratio increases from 1.0 to 5.99.The effect of a boiling water pretreatment on the rate of diffusion relative to untreated samples depends upon the temperature at which they are compared. Even though the density increases upon treatment, the rate of diffusion is greater when dyed at 60° but lower when dyed at 102°. The wet treatment lowers the activation energy for diffusion to about 18 kcal/mole, a value which is nearly independent of draw ratio.

“…Not only is there a large increase in the quantity of dye adsorbed at low pH ( attrilnrted -to adsorption on amide sites). but the nylon is slowly hydrolyzed and dye adsorption continues to increase over an extended period of time ( 19,24]. (It is interesting to note that nylon is stable in acid solutions in the absence of dye [9.…”

“…Dyeing with acid dyes can result in a certain degradation of the polymer [37][38][39]. The degree of hydrolysis depends on the concentration of the dye and the number of sulfonic acid groups per dye molecule [40].…”

“…Many works have been interested on the dyeing of nylon fibers and many classes of dyes have been used 1,2 . The presence of terminal amino groups in nylon fibers imparts substantivity towards anionic dyes, this made that coloration of nylon was usually achieved with acid dyes, but the major problem was related to their poor fastness properties 3,4 .…”

This research work involves the synthesis, the characterization, and the dyeing application of some reactive dyes between polyamide fibers. All the dyeing parameters have been studied, pH 4 was registered as the optimal pH value of dyeing polyamide fabrics with the synthesized dyes. The color depth as measured by the K/S value, the colorfastness to washing and light were also evaluated. Under UV exposure, intense emission of orange red was observed for dyed polyamide. Potential applications of this technology include protective clothing, textile-based sensors, and smart tagging.
