“…Moreover, towards alkalinity, the -COOH of wool keratin may face a weak interaction with colorant -OH, thereby resulting in a low color strength. However, in an acidic medium, the amino group of keratins gets protonated and amido linkages are easily available for binding with the functional site [34,35]. Hence, the results displayed in Figure 2c reveal that the dyeing of irradiated wool (RW) should be done using an irradiated methanolic extract with a pH of 3 to get excellent results.…”

Sustainable Extraction of Colourant from Harmal Seeds (Peganum harmala) for Dyeing of Bio-Mordanted Wool Fabric

et al. 2022

The recent pandemic scenario has caused demand for green products that have medicinal aspects, as well as greener approaches for global health. Natural dye from plants, particularly from harmal seeds, is an excellent alternative to carcinogenic yellow synthetic dyes. The current study has been conducted to isolate natural colorants from harmal seeds in methanolic medium through Gamma-Assisted Extraction (GAE). The dyeing variables that are necessary for shade development before and after mordanting were selected. It has been found that 6 kGy is the optimal absorbed dose for extraction of colorant from 6 g of powder to isolate the colorant in the methanolic medium through the Gamma-irradiated extraction mode (GAE). To get excellent results, 30 mL of methanolic extract containing 6 g/100 mL of Glauber salt was sued for dyeing of irradiated wool at 45 °C for 65 min. For improving the color strength and acceptable rating of fastness, 9% of henna, 3% of acacia, 10% of turmeric, and 7% of pomegranate extracts as pre-bio-mordants as well as 7% of acacia, 3% of pomegranate, 9% of henna, and 10% of turmeric extracts as post-mordants have given high results compared to when chemical mordants have been used. It was concluded that Gamma-ray treatment has excellent color strength in the dyeing of bio-mordanted wool using harmal seed extracts under mild conditions, and has good fastness ratings after using chemical and bio-mordanting methods as well.

“…Various reports have been published on the coloration and functionalization of different textile fibers using natural dyes. However, most studies have been focused on natural fibers such as wool, silk, and cotton [1][2][3], while the number of studies on natural dyeing of synthetic fibers is comparably low. Recently, several attempts have been made to apply natural dyes on synthetic fibers such as polyester [4][5][6].…”

Sustainable Dyeing Process for Nylon 6 Fabrics by Rhubarb Flower Using Different Bio-Mordants

2023

View full text Add to dashboard Cite

The purpose of this study is to propose a fully sustainable dyeing process for nylon 6. In order to achieve this goal, Rhubarb flower parts were used to produce a brown hue on nylon 6 fabric. The effects of dyeing parameters such as dyeing time, temperature, dyebath pH, M:L, salt addition, dispersing agent, and dye concentration on color strength were investigated. Using 100%owf dye in an acidic medium at boil and the material to liquor ratio of 1:30 for 75 min was determined to be the optimal condition for dyeing nylon 6 with rhubarb flower. In order to achieve acceptable color fastness, four natural mordants were applied, including walnut husks, pistachio hulls, pine cones, and green coffee. Colorimetric measurements revealed that mordanting did not affect the hue of the color compared to the non-mordant sample. In addition, diverse natural mordants produced the same color (i.e., brown) with varying color strengths, of which 10%owf walnut husk generated the strongest color. Bio-mordanted samples were also found to have excellent color fastness, thereby providing an effective substitute for metal mordants.

“…use this plant as a natural dye (lips coloring). Juglans regia bark extract has also been used to dye wool fabrics [12,13]. Acrylic is one of the fibers that are difficult to dye because of the electrostatic repulsions which can develop between the carboxylate groups COO-of the dyes and sulfonates SO 3 -of the acrylic.…”

Exploration of the Fluorescence Property of Acrylic Fibers Dyed with the Residues Extract of Juglans regia Barks

et al. 2022

This study aims to check the fluorescence property of acrylic fabrics dyed with Juglans regia bark extract. Fluorescence measurements have been developed on the aqueous extract and acrylic samples. The extraction process was assisted by a microwave with the following conditions: a concentration of 5 g·L−1, a power of 850, a pH of 5 and an extraction duration of 4 min. Afterwards, the dyeing quality was assessed by measuring the color strength (K/S) and the photoluminescence intensity (PL) of acrylic fibers dyed at 350 W for 3 min, with the extract already prepared. The effect of certain factors (pH, power, concentration and duration of dyeing) on the dyeing process was also investigated. Subsequently, this process was optimized thanks to the surface response method in order to maximize the photoluminescence intensity of dyed acrylic fibers. Best dyeing properties were achieved at 500 W, pH 2 for 4 min. The results showed good washing fastness and acceptable light fastness.
