“…It has been found that 35 mL of dye bath after U.S. treatment for 30 min has also given excellent results, where it contains 3 g/100 mL of salt as an exhausting agent. Hence, overall, it can be seen that statistically, the reduction in dyeing level shows that U.S. treatment to Harmal extract used for dyeing of silk is cost energy and time effective in nature (Adeel et al 2021b;Ranjha et al 2021). The data presented in Tables 4 and 5 reveals that most of the fabric dyed shows brighter shades with a more reddish-yellow hue, but the optimum fabric dyed at 70°C for 45 min using 35 mL of U.S. treated dye bath of 7 pH containing 3 g/ 100 mL of salt is brighter (L* = 78.59) in the shade and less redder (a* = 5.47) but much more yellower (b* = 41.85) in tone.…”

Sustainability in all applied fields particularly in textiles is to protect our globe, environment, and community, where green dyed products are playing their role. For the current study, Esfand (Peganum harmala) has been explored using a green isolation tool, i.e., ultrasonic (U.S.) rays, and applied onto fabric. Different dyeing parameters have been explored statistically through response surface methodology by employing temperature (50-80°C), time (25-65 min), extract volume (15-55 mL), salt (1-5 g/100 mL), and dye bath pH (4-7) through series of experiments. For developing new shades, green mordants such as elaichi, neem, turmeric, and zeera have been utilized. It has been found that exposure of 35 mL extract of 7 pH containing 3 g/100 mL of salt as exhausting agent to U.S. rays for 30 min for the dyeing of silk at 70°C for 45 min has given maximum color strength with reddish-yellow shades. Color characteristics obtained in the CIE Lab system reveal that 5% of turmeric as meta bio-mordant has given good quality reddish-yellow shades. It is found that U.S. rays have not only good potential to isolate colorant followed by dyeing of silk under reduced condition but also the application of bio-mordants have made the process more greener, sustainable, and cleaner.

“…In many cases, the type of mordant, the chemicals used during mordanting, and the method of mordanting affect the hue and quality of dyed the textile. Also, it has been stated that the mordant is very signi cant related to natural dyes in natural dyeing (Adeel et al 2022). The wool yarns were mordanted by copper sulfate (5 % o.w.f.…”

Considering the growing importance of natural colorants and sustainable products, the research on application of natural dyes has been focused on new color resources, identi cation and standardization of natural dyes. Hence, the extraction of natural colorants available in Ziziphus bark was performed by ultrasound technique and its application on the wool yarn to produce the antioxidant and antibacterial bers. Results indicated that the optimize condition for extraction process was achieved at ethanol/water (1/2 v/v) as solvent for extraction, concentration of ziziphus dye 14 g/L, pH 9, extraction temperature 50 ºC, time 30 min, and L.R ratio 50:1. Moreover, the effect of important variables for application of ziziphus dye on the wool yarn were investigated and optimized temperature 100°C, concentration of ziziphus dye 50% o.w.f., time for dyeing 60 min and pH 8, and L.R 30:1. The reduction values of Gram-negative and Gram-positive bacteria on dyed samples at optimized condition were 85% and 76%, respectively. Moreover, the antioxidant property of dyed sample was 78%. The color variations on the wool yarn were produced with diverse metal mordants, and color fastness properties were measured. Ziziphus dye not only can be used as an origin for a natural dye, but also provided the antibacterial and antioxidant agent on the wool yarn, which can be a step towards the fabrication of green products.

“…The hazardous effects of artificial dyes on human health like carcinogenic or mutagenic activity [ 1 ], and the contamination of the environment caused by wastewater discharged by dye industry [ 2 ] led the industries to search new sustainable and less harmful dye sources [ 3 ]. Natural dyes are more environment-friendly than artificial dyes and may have biological benefits [ 4 ].…”

Background Proven toxicity and environmental burdens caused by artificial dyes have motivated dyeing industries to turn to natural alternatives. Plant-based dyestuffs are an interesting group of alternative crops. Reunion Island located in the Indian Ocean is the only European region in the southern hemisphere. It has a great number of assets to find new molecules in the abundant plant biodiversity. However, the dye-producing plants diversity in this island had not been documented to date. Methodology The assessment of the Reunion Island’s plant biodiversity through the “PLANTIN” project allowed us to establish here the first ethnobotanical inventory of plants growing on Reunion Island which may have promising properties as a new alternative source of dyes or colorants for the industries. First, an ethnobotanical survey focused on the uses of plants traditionally used in dyeing was conducted on local stakeholders. Then, the importance of different criteria (e.g., endemicity, accessibility and cultivability, plant organs used for the extraction, industrial interests of the species, etc.) has been considered to establish a classification method of the species, to finally select the most interesting plants which have been further harvested and investigated for their coloring property and dyeing application on natural fibers. Results The results showed that local people have accumulated traditional knowledge of dyeing plants, but that this approach had been discontinued in Reunion. The uses of 194 plant species potentially rich in dyes or pigments, belonging to 72 different families, with diverse botanical status (endemic, native, introduced or alien-invasive species) have been recorded. Then, 43 species were harvested and their coloring property were investigated. It demonstrated that dyes extracted from promising species, e.g., Terminalia bentzoe, Weinmannia tinctoria, Thespesia populnea, Erythroxylum laurifolium, Morinda citrifolia, Leea guinensis, Ochrosia borbonica, Danais fragrans, Terminalia cattapa, Casuarina equisetifolia, and Coccoloba uvifera, amongst others, could be used as new textile dyes. Their efficacy in the wool and cotton dyeing has been successfully demonstrated here. Conclusion These plant-based dyestuffs showed promising coloring properties with different shades that could meet industrial application requirement. It's an area that could promote local cultural inheritance, create opportunity for business and farmers, and that can make a significant contribution to preserving endangered native species by supporting reforestation schemes. Additional researches are in progress to evaluate the safety of these plant-based colored extracts, their chemical composition and biological activities.
