Dyeing and fastness properties of Quercus robur with natural mordants on natural fibre

Abstract

Dyeing potential of a natural dye extracted from Quercus robur L. (fruit cups) with a combination of Salix alba L. and Populus deltoides Bartram ex marsh (wood ash) mordants was studied on wool, cotton, silk and pashmina fabrics. Experiment was carried out in different combinations including and excluding mordants by adopting different mordanting methods. Dyeing performance was assessed in terms of dye absorption (%), Colour values (CIELAB), Colour strength (K/S), and fastness properties. The dye in combination with mordants showed significant importance and resulted in different shades on wool, silk and pashmina fabrics. However, the cotton fabric did not show much affinity for the dye and mordant and showed less affinity for the dye and mordants with lower values of colour quality and retention grades. Fastness properties of all dyed fabrics recorded excellent grades with slightly lower grades in unmordanted dyed samples.

The Blue Water Footprint of Block-printed Batik Coloured by Natural Dye of Myrobalan (Terminalia bellirica Roxb.) Mordanted by Alum and Copperas

“…1a) is darker than the clothes mordanted by alum (Fig 1b). The positive b* value indicates tendency to form bright yellowish tone, while the negative refers to blue colour [14], [15]. High value of ∆b* therefore, indicates a yellow colour, and visually this is in line to the result presented in Fig.…”

“…The wax, natural dyes, and water attached or absorbed by each clothes were also measured according to our previous research [13]. Colour measurement of the Myrobalan extract and the coloured clothes were conducted using a Minolta CR-200 chromameter resulting the L*, a*, and b* parameters which were used to calculate the total colour change (∆E) [14], [15].…”

“…Production technologies of natural colorants from plants could vary from simple solvent extraction to sophisticated techniques depends on the product requirement and its purity. The extraction procedure such as soxhlet method to obtained colour from Quercus robur L. 60 , supercritical fluid extraction and pressurized liquid extraction on annatto seeds and jabuticaba skins 61 , and microwave assisted extraction used on milkweed leaves to get its colour 62 are among several techniques commonly applied. After the extraction process, purification and drying are essential to ensure the quality of the finished product.…”

Rumex abyssinicus (mekmeko) extract as cleaner approach for dyeing in product manufacture: Optimization and modeling studies

“…Many researchers showed that various natural‐based materials develop color in combination with inorganic mordants, namely, Fe, Cu, Zi, and Al. The mordants help the dyes to fix well and then prevent the color from fading due to exposure to light and washing out . In view of these issues, persisting with natural alternative materials for dyeing, this study attempted the use of plant constituents from mekmeko for coloring of leather.…”
