“…3. The spectrum A shows two peaks, one at 475 nm corresponding to indicaxanthin and the other at 538 nm corresponding to betanin (José et al, 2001;Guesmi et al, 2012a). After separation, the majority portion (betanin) was confirmed by the mass spectrum (Fig.…”

“…Moreover, light fastness of the samples was in the range of 4-5 (fair) according to the blue scale standard, and there was not much difference between two dyed samples. In all cases, fastness properties of nylon were higher than wool which may be attributed to better arrangement of dye molecules within fiber polymeric structure as well as more compact structure of nylon, which makes hard scrubbing out of the dye molecule (Guesmi et al 2012;Shams-Nateri 2011).…”

“…Recently, with increasing the number of research laboratories which study on traditional dyeing methods, dyeing of textiles using natural dyes is further considered because of environmental issues. Natural dyes, indeed, are eco-friendly and exhibit better biodegradability with higher environment compatibility (Shahid et al 2013;Guesmi et al 2012).…”

In this study, dyeing, fastness and adsorption isotherm characteristics of madder natural dye on the wool and nylon yarns were investigated. Wool and nylon were first mordanted by aluminum sulfate, dyed with natural dye extracted from madder root, and the rates of dyeing and equilibrium times were determined and compared. Nylon, indeed, showed higher dyeing rate and reached equilibrium at comparatively lower times. Adsorption isotherms were identified to be a Nernst-type substrate. In addition, the affinity (Dl°), free energy (DH°) and entropy (DS°) of madder on the wool and nylon were calculated. The obtained results from thermodynamic data indicated that with temperature rise, the partition ratio and the standard affinity significantly decreased. The affinity of madder natural dye to the nylon was gradually higher as compared with wool. Wool, indeed, displayed higher negative values for both enthalpy and entropy changes as compared to those values of nylon. The colorimetric and fastness properties of madder natural dye on nylon were overall superior than on wool.

Metal mordanting in dyeing with natural colourants

2016

View full text Add to dashboard Cite

Metal mordanting, or the application of metal salts, is a common method of improving the light fastness in dyeing with natural colourants. This review presents the results from a survey of the literature on metal mordanting to assess what levels of correlation exist between mordant‐induced effects (changes in colour and colour depth) and the changes in light fastness, what is known about the mechanisms of mordant‐induced improvements of light fastness, and how the salt levels used in coloration processes compare with the limits on metal levels in wastewater and on the dyed substrates. No strong interrelationships are found between the mordant‐induced effects and light fastness improvements. Knowledge about mechanisms of mordant effect on light fastness appears, in large part, to be derived from empirical correlations. However, as light fastness is affected by a multitude of factors, the correlations do not always hold true. It is found that residual metal contents in spent dye/mordanting liquors are generally not reported. However, with rough calculations, it is estimated that, with even the lowest reported salt concentrations, the metal contents in spent liquors exceed environmental release limits. The metal contents on dyed substrates are also not generally reported, but similar estimations show that the contents of heavy metal on dyed substrates (when copper and chromium salts are used as mordants) also exceed limits. On the basis of these observations, the authors make suggestions for elements to be included in investigations on furthering the use of natural colourants in textile dyeing.
