“…Natural dyes are bio-colours recovered and extracted from natural sources, and their stability is solvent [1,2]. The demand for natural dyes has been increasing in the current moment due to rising environmental concerns [3,4]. Many chemicals, such as synthetic dyes, have mutagenic and carcinogenic components used daily in the synthesis formulation and finishing processes [5].…”

Green products such as plant pigments are gaining fame globally due to their excellent ayurvedic and biological characteristics. In this study, microwave (M.W.) has been employed to isolate colourant from black pepper (Piper nigrum L.), and bio-mordants have been included to obtain colourfast shades. Central Composite design (CCD) was formulated under response surface methodology (RSM) to optimize dyeing variables statistically. The results obtained after a series of experiments show that using 35 mL of irradiated acidic extract (RE = 6 min.) of (pH4) in the presence of 1 g/100 mL of table salt as an exhausting agent at 65 °C for 55 min has demonstrated excellent colour depth (K/S) onto microwave-treated silk fabric (RS = 6 min). By applying bio-mordants, it has been found that walnut extract (1.5%), pinenut hull extract (1%), and orange peel extract (1.5%) are there before dyeing. In contrast, walnut extract (1.5%), pinenut hull extract (1.5%), and orange peel extracts (1.5%) after dyeing have shown colourfast shades of high strength. Comparatively, salts of Al+3 (1.5%), salts of Fe+2 (1.5%), and T.A. (tannic acid = 1.5%) before dyeing, while salts of Al+3 (0.5%) and salts of Fe+2 (2%) and T.A. (Tannic acid = 1%) after dyeing, have given good results. It has been observed that the use of M.W. radiation has not only improved the yield of dyes extracted from leaves when applied to silk fabric but also the inclusion of the optimum amount of bio and chemical mordants have resulted in moderate to good and excellent colour fastness ratings.

“…Most of these variables have positive effects on colour strength versus extract amount, time, temperature, pH of the dye bath, and concentration of salt for attaining high exhaustion, but the effects of salt, pH of dye bath and time are extremely significant (p=0.000). Mordanting is regarded as essential in natural colouring since it is the only approach to address the problem of low fastness [32,33]. In comparison to chemical salts of Al 3+ , Fe 2+ , and sodium potassium tartrate, green plant anchors i.e.…”

Natural dyes have grown in popularity due to their eco-friendliness. They can be used as a substitute for synthetic dyes to minimize environmental pollution. This research investigates the natural colouring behaviour of haar singhar flower (HSF) extract in cotton dyeing. Colorant was extracted under various conditions utilizing various extraction mediums such as aqueous, basic, and acidic. On cotton, it was discovered that applying 55 mL of aqueous extract containing 1.5 g/100 mL sodium chloride for 40 minutes at 70 °C yielded the best colour output. A new hue with good colour fastness was developed utilizing chemical and bio-mordants. The existence of nyctanthin as a colouring agent in haar singhar flowers was discovered through FTIR analysis of the extract. The CIE Lab system revealed that using 2 g/100 mL of pistachio shell as a bio-mordant resulted in good quality reddish yellow hues. It was discovered that ultrasonic radiations have a high potential for isolating colourants and dyeing cotton fabric under decreased conditions of temperature, time and volume. The application of biomordants has made the procedure greener, more efficient, and safer.

N ATURAL dyes are colours generated from natural sources. Many chemical processes using petrochemical-based dye intermediates are used in the creation of synthetic dyes, which use a lot of energy and release harmful toxic substances into the environment. So they have been substituted with natural ones that have many advantages, and despite these advantages, natural dyes have some serious disadvantages because of the technical and environmental challenges related to the production and use of natural dyes. To extract dye from its source, they must use a specialized process. The following are some ways of extracting natural colours from their sources: Aqueous extraction, Solvent extraction, Acid and alkali extraction, Supercritical fluid extraction, Ultrasound-assisted extraction, Enzyme assisted extraction. Many bioactive compounds are found naturally in plants. Plant-derived dyes such as red onion peel, Psidium guajava leaves, saffron flower, banana peel, and Ficus leaves are extensively used to colour textiles in the textile and fashion industries.
