“…By comparing the results obtained here with previous studies on natural dyes, it was concluded that metal cations used as mordants are able to provide coordination complexes with wool amino acid groups (NH 2 , COOH) on the one hand and with functional groups of juglone (OH, C=O) on the other, resulting in bridge formation .…”

In many countries, the search for new sources of natural colourants has recently been intense. This paper deals with the extraction procedure, dyeing behaviour, antifungal activity, and ultraviolet protection of Pterocarya fraxinifolia as a new natural source of dyes. Juglone was found as the main extracted compound after characterisation by ultraviolet‐visible spectrophotometry and Fourier transform infrared spectroscopy. Mordanting and subsequent dyeing of wool with extracted juglone were then performed to study the dyeability and antifungal activities. Three metal salts, aluminium sulfate, copper sulfate, and iron sulfate, were used as chelating materials. The colorimetric properties of samples were evaluated using a reflectance spectrophotometer. Furthermore, the washing and light fastness properties were tested according to ISO 105‐CO3:1989 and ISO 105‐B01:2014. Interestingly, we found P. fraxinifolia to be a source of strong antifungal compounds against microorganisms. Extracted juglone also exhibited strong protection activity against solar ultraviolet rays.

“…We also observed a further decrease in L* as the concentration of mordants was increased during the premordanting processes. As a result, we can conclude that premordanting is a very beneficial process for obtaining bright colours in nylon 6 dyed with henna and P. fraxinifolia leaf extracts [41].…”

“…The circles in the figure indicate where each dye molecule can interact with nylon 6 and tannic acid. Our previous study of the dyeing of wool with madder extracts showed that wool macromolecular chains interacted with aluminium salt and clay minerals prior to dyeing [30,31,41].…”

Acid and disperse dyes are two well‐known synthetic materials that are primarily used for dyeing of nylon 6 fibres. Despite their good performance, several negative impacts on the environment, including air and water pollution, are major concerns to researchers. An alternative ecofriendly approach to the dyeing of nylon 6 is the use of natural dyes, given their abundant natural sources, biocompatibility, biodegradability, non‐toxicity, non‐allergic responses, and non‐carcinogenic effects on human life. Based on these advantages, we extracted polyphenolic dyes from henna leaves, pomegranate rind, and Pterocarya fraxinifolia leaves and studied the dyeability on nylon 6 fabric using three compounds of aluminium sulfate, tannic acid, and tin chloride as toxic and non‐toxic mordants before dyeing. Fourier transform infrared spectra of the nylon 6 fabric confirmed the coordination complexes and π–π bonding between the mordants and the dyes. Colorimetric and fastness results showed that the mordants increased the colour strength and improved the fastness properties of the fibres. Our results suggest that tin chloride and aluminium sulfate as metal mordants can be successfully replaced with tannic acid as a biomordant in the natural dyeing of nylon 6. Also, cost assay showed that dyeing of nylon 6 with extracted natural dyes from waste leaves could be a sustainable and economical substitute for synthetic dyeing.

“…The effectiveness of mordants and other compositions (clays, enzymes) [17,18] and extraction procedures [19] in improving dyeing efficiency and use of waste materials from new sources for dye extraction have been reported [20]. In fact, researchers have provided significant evidence that had led to improvements in fastness and affinity or found new sources of natural dye extracts.…”

The effectiveness of mordants and other compositions (clays, enzymes) [17,18] and extraction procedures [19] in improving dyeing efficiency and use of waste materials from new sources for dye extraction have been reported [20]. As there has been hardly any previous research on the application of plant-based hair dyes, this work is a starting point to introduce a new dyeing agent into the cosmetic industry.…”

Walnut green husk is one of the main waste products from walnut and could be used as a source of natural dyeing compounds such as juglone. The present study was conducted to evaluate the effective use of walnut green husk extract as a natural hair dye. Dyeing properties, fastness and antimicrobial behaviours of dyed hair and also a skin irritation test for natural hair dye on rat skin were examined. When the extract was mixed with ascorbic acid as a developer, ferrous sulphate as a mordant, and Aloe vera extract used as a secondary mordant and also a cosmetic ingredient, the reaction resulted in a dark-brown colour on hair samples. The dyed hair exhibited appropriate colour strength having excellent morphology for a hair surface coated with dye molecules. In addition, the dyed hair possessed good resistance to washing and daylight fastness, without any irritant properties as shown in a rat model, although high concentrations of iron-based mordant may be problematic for long-term usage. This paper also suggests the use of natural mordants such as lactic and oxalic acids to avoid any probable risks. Walnut green husk extract was an appropriate natural hair dyeing agent in practice and showed maximum antimicrobial activity compared with semi-synthetic and commercial hair dyes. The results demonstrated that walnut green husk can be used as an economical, valuable, eco-friendly and safe source of dyeing and antimicrobial agents for cosmetic products.
