“…rays have been selected to enhance silk fabric's sorption behaviour and break the clusters of functional molecules into small molecules. These rays tune the fabric surface and enhance uptake behaviour [10,15]. For extraction, these rays enable small molecules, after rupturing the plant wall, to interact with solvent molecules rapidly.…”

“…Their effluents are nontoxic, biodegradable, and could be reused as a bio-fertilizer to improve crop growth [8]. Secondary metabolites of the plant extracts are used as tonic and herbal system that transfers their biological activities when employed on matrices such as silk, wool, and cotton [9,10]. The most vital factor is that the cultural heritage with a broad spectrum of colours is now being revived as state-ofthe-art for the colouration of different substrates [11,12].…”

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.

“…At 60 °C, pre-chemical mordanting with 2.5% Al 3+ , 1.5 g/100 ml Fe 2+ , and sodium potassium tartrate, as well as pre-bio-mordanting with 0.5 g/100 ml walnut and pine nut shells and 2.5% pistachio shell gave good shade strength and fastness features. Chemical mordants have given vibrant colours as well as superior colour strength when compared to bio-mordants [34][35][36]. As a result, plant-based anchors can be used to substitute metal salt in the process, making it more sustainable.…”

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.

“…Microwaves are electromagnetic rays being used for the isolation of natural dyes gaining fame because these rays act upon the system uniformly (Yameen et al 2022;Zin et al 2022). These rays when collide with the system, penetrate deeply and save kinetics in the isolation process these rays when come in contact with plant powder, weaken its cell wall and during boiling make it easy for functional molecules to leach into solvent via solid-liquid interaction by consuming less solvent, time and energy (El Sayed et al 2023;Mumtaz et al 2022).…”

The effect of microwave (MW) radiations on wool and silk dyeing with extract of Arjun bark (Terminalia Arjuna) powder has been investigated. The wool and, silk & dye powder were irradiated to MW treatment for up to 5 minutes. Dyeing was performed using un-irradiated and irradiated wool and silk with irradiated and un-irradiated dye powder extracts. SEM and FTIR analyses were performed to observe morphological and chemical changes in the fabric's surface before and after irradiation. Different dyeing parameters have been optimized using a central composite design through response surface methodology. Pre- and post-mordanting was done using 0.5-2.5g/100mL of sustainable chemicals and mordants. All dyed fabrics were subjected to color analysis using a Spectra Flash spectrophotometer (SF600). ISO standard methods were employed for colorfastness to light, washing, and rubbing. It has been found that 45mL of acidic extract of 3pH when employed at 75°C for 45 min after microwave treatment up to 2 min., the dyed silk fabric has furnished high yield after finishing. For wool, 35mL of methanolic extract of 5pH when employed at 45°C for 55 min after MW treatment up to 1 min. The dyed wool fabric has furnished a high yield after finishing. Before and after the dyeing of silk and wool, the Selected chemical and bio-mordants have developed colorfast shades.
