“…Plants have been the greatest source of dyes, notably roots, leaves, berries, barks and wood. As a result of rapid deforestation dyes sources from vegetation has not been commercialized (Silva, 2020;Chandanshive, 2018;Ayedet al, 2017). In recent times dyes have been obtained from coal and petrochemicals .…”

“…Other dyes are initially applied as a mordant, an inorganic material that leads to the dye precipitation as an insoluble salt Moreira et al, 1998;Samanta, 2011). Another dye fastening techniques vat dyeing where soluble colourless compounds is absorbed by fibre materials, oxidized to the insoluble coloured compounds making resistant to the fading effects of light, chemicals and washing ( Faisal et al, 2007;Silva, 2020).…”

The present study investigated the effect of pH on the spectral properties of Acid Orange 7 and Plasmocorinth B azo dyes in aqueous systems. Several concentrations of each dye were prepared from a stock solution. The molar extinction coefficient (ԑ) and maximum absorption wavelengthߣ ௫ of the dyes in different pH environments were measured using a UV/Vis spectroscopy. Dye absorbance was measured between λ=200 nm-800 nm. The results indicate that the maximum absorption wavelengths ߣ ௫ of AO7 and PC-B were determined at 485 nm and 528 nm respectively. The molar extinction coefficient (ԑ) was calculated at Acid Orange 7= 20647 dm 3 . Mol -1 .cm -1 and Plasmocorinth B= 19203 dm 3 .mol -1 .cm -1 . The finding shows that pH has no effect on the absorbance of the aqueous dye solutions indicating dye stability under different pH levels.

BackgroundNatural dyes used since historic times for coloring food, leather, textile fibers, and paint body parts. The use of natural dyes has suffered drastically under the influence of modern technologies in the textile industry and socio-economic changes. Hence, ethnobotanical studies of indigenous dye plants and dyeing craft in local communities are urged to protect their potential ecological and economic value. MethodsWe conducted semi-structured surveys on dye plants and traditional craft in 11 Monpa villages of Mêdog County, South-east Tibet, China. The cultural significance of local dye plants was evaluated by an index of cultural importance (CI). Field research was conducted to record the indigenous madder (the root of Rubia wallichiana Decne.) dyeing craft. An experiment was performed with aqueous extract and ethyl alcohol extract of residue remained after water extraction. These two dye solutions were respectively used to dye two fabrics with two biomordants and two metallic mordants by three mordanting methods. We evaluated color properties that were characterized by physicochemical evaluations using UV-visible spectroscopy and FTIR analysis. The dyed fabrics were evaluated by indicators of color strength and fastness including washing, rubbing, and perspiration. ResultsAltogether 15 species belong to 12 families were listed as dye plants, which were used in cloth and food dyeing. The CI of R. wallichiana was highest. Monpa ethnic group used madder directly or with metallic mordants. It was found experimentally that biomordants and metallic mordants were comparable in improving the dyeing properties of indigenous madder. The dyeing properties of both extracts of madder were equal or ethyl alcohol extraction was marginally better.ConclusionsUse of dye plants and indigenous knowledge of dyeing still present in the Monpa ethnic group. Our experiment revealed the feasibility of enhancing the dyeing property and reuse of the residue from madder dyeing. The improved dyeing and reuse of residue can improve the ecological and economic benefits of local meanwhile provide basic application research for the subsequent commercialization of plant dyes.

“…The pollution of chemical dyes to the environment has become increasingly prominent, and its potential harm to the human body has also begun to attract attention. 7–9 With the public's enhanced cognizance to eco-safety and health concerns, plant dyes are favored and respected by people for their excellent environmental compatibility and health care functions and are widely used in the preparation of a variety of high value-added textiles. 5,10,11 Textiles dyed with plant dyes retain the unique medicinal and aromatic components of plants, which have superior human and environmental safety.…”

Plant dye is a promising dyestuff to be used in textiles due to its unique environmental compatibility. However, currently there is no effective method for the identification of plant-dyed and chemical-dyed textiles. In this study, near-infrared (NIR) spectroscopy combined with three kinds of pattern recognition methods, namely soft independent modeling of class analogy (SIMCA), partial least squares (PLS) regression and principal component regression (PCR), were applied to identify cotton fabrics dyed with plant and chemical dyes. A total of 336 plant dye and chemical dye dyed cotton fabrics were prepared and the NIR spectra were collected; 267 samples were used as the calibration set, while the remaining 69 samples were used as the validation set. After pretreatment with the Savitzky–Golay first derivative, the calibration model was constructed. In the SIMCA model, the correct recognition rate values of the calibration and prediction sets were 100% and 98.55%, respectively. The PLS model showed that the number of principal components (PCs) and the correlation coefficient ( R2) were 8 and 0.9978, respectively, and the results of PCR were PC = 10, R2 = 0.9937. Both methods were satisfactory for the predicted results. The overall results indicated that NIR spectroscopy could be used for rapid and nondestructive identification of plant-dyed cotton fabrics and chemical-dyed cotton fabrics.
