“…Anthraquinone sources under active study for dyeing purposes include Rubia cordifolia, and Rubia tinctorum which contains alizarin, purpurin, emodin and rhein as common pigments [36,37]; Rheum emodi which contains contains emodin and physcion colourants [38]; Cassia nodosa, which contains rhein [39]; and Morinda angustifolia, which contains rhein and emodin dye compounds [40]. Anthraquinone pigments have been isolated in concentrations in excess of 30 mg/(g dw) (dw: dry weight) from Morinda citrifolia, R. emodi, Rheum undulatum, Rubia cardigolia and Tectona grandis [38,41,42].…”

Synthetic dyes are by far the most widely applied colourants in industry. However, environmental and sustainability considerations have led to an increasing efforts to substitute them with safer and more sustainable equivalents. One promising class of alternatives is the natural quinones; these are class of cyclic organic compounds characterized by a saturated (C6) ring that contains two oxygen atoms that are bonded to carbonyls and have sufficient conjugation to show color. Therefore, this study looks at the potential of isolating and applying quinone dye molecules from a sustainable source as a possible replacement for synthetic dyes. It presents an in-depth description of the three main classes of quinoid compounds in terms of their structure, occurrence biogenesis and toxicology. Extraction and purification strategies, as well as analytical methods, are then discussed. Finally, current dyeing applications are summarised. The literature review shows that natural quinone dye compounds are ubiquitous, albeit in moderate quantities, but all have a possibility of enhanced production. They also display better dyeability, stability, brightness and fastness compared to other alternative natural dyes, such as anthocyanins and carotenoids. Furthermore, they are safer for the environment than are many synthetic counterparts. Their extraction, purification and analysis are simple and fast, making them potential substitutes for their synthetic equivalents. Graphic Abstract

The objective of the present study was to compare between the mixed dyeing of wool fiber in one and two dye baths using natural indigo (Indigofera tinctoria) and madder colorants (Rubia tinctorum). Based on the reduction and oxidation reaction conditions under the same dyeing mechanism for the indigo and madder colorants, the exhaustion rate of the mixed dyeing in two dye baths was higher than that for mixed dyeing in one dye bath. The poor exhaustion rate that was achieved when dyeing in a single dye bath indicated the incompatibility of both dyes when mixed in one dye bath. However, both methods achieved a rigid fixation as confirmed by washing-fastness test 105C6A01.

“…Cette plante rubiacée aux fleurs jaunes, a été séchée à l'ombre afin de conserver son pouvoir tinctorial. Les racines ont été broyées afin d'en séparer l'écorce et le bois inutiles, puis pilées et tamisées (tamis métallique 1 à 1,5 mm) (Chemchame et al, 2016). Les racines de Rubia tinctorum ont été récoltées à Taddamout (région de Midelt, Maroc) en début du printemps, puis séchées à l'ombre pour conserver leur pouvoir tinctorial.…”

Lofti et Zakarya., J. Appl. Biosci. 2017 L'éco-efficacité du recyclage d'un rejet de teinture végétale à la garance (Rubia tinctorum) 10877Journal of Applied Biosciences 111: 10877-10881 ISSN 1997-5902 L'éco-efficacité du recyclage d'un rejet de teinture végétale à la garance (Rubia tinctorum) ABSTRACT Objective: The aim of this study is to evaluate the eco-efficiency of recycling rejects of dyeing bath from madder.The present study consisted in the eco-efficiency of a plant dye by recycling of the produced wastewater of madder dye bath. Methods and results: in this study, we used the roots of the madder collected in the Midelt region (Morocco) to dye the skeins of wool which we had previously etched with aluminum sulfate and calcium tartrate. The wastewater from the dye baths was reused to dye new yarns. Before using this wastewater, we measured the absorbance for each release and deduced its concentration by means of the calibration line produced. The value of this concentration allows us to know whether we recycle the bath to be rejected or to refill it with dye. Conclusion and application of research: Our work shows that the recycling of the dyeing bath we save money, water and energy (cleaner production) and the environment.
