“…Color characteristics are highly affected by the type of mordant used [42]. In Figure 5, it is observed that while the K/S values of dyed samples with Alum and unmordanted increased depending on concentration, the K/S values of dyed samples with ferrous sulfate did not change much for both mushrooms extracts.…”

“…Natural dyes are mostly non-substantive and must be applied on textiles by the help of mordants, usually a metallic salt, having an affinity for both the coloring matter and the fiber. After combining with dye in the fiber, these metallic mordants turn into an insoluble precipitate or lake; hence, both the dye and mordant get fixed to become wash fast to a reasonable level [41,42].…”

In recent years, the use of synthetic dyes and pigments in textile finishing companies has been discussed for their harmful effects on human health and environment. For this reason, the use of plant-based dyestuffs from the nature has begun to increase because of the biodegradability, nontoxicity, human health and waste water contamination. Natural dyes are substances synthesized by some plants, animals, lichens and fungi in nature. Fungal species, including lichenized fungi have been used as natural colorants in different parts of the world throughout the history. In this study, natural dyes were extracted from Lactarius deliciosus and Lactarius sanguifluus collected from Osmaniye province (East Mediterranean region) of Turkey. The adsorption UV-Vis spectra of the mushrooms were measured to examine major colorants, and FTIR analysis of natural dyes obtained from the mushrooms extracts was performed. According to the analyses, major colorants in the edible Lactarius species could be azulene and its derivatives. Wool yarn (for carpet) was dyed with these natural dyes by using different mordants. CIELab (L*, a*, b*, c* and h), color differences (ΔE) and color strength (K/S) values of dyed wool yarns were determined. According to the dyeing results, cream and brown colors were obtained from L. deliciosus and L. sanguifluus respectively; the use of mordant (ferrous sulfate) increased the color strength of dye goods. Besides, properties of rubbing and washing fastness were investigated, and the results of the dyed yarns were low/moderate. This is the first study on dyeing of wool yarns with natural dyes obtained from L. deliciosus and L. sanguifluus collected from East Mediterranean (Osmaniye province) of Turkey.

“…The present method for isolating dyes from wool is commonly used [8,9]. Since wool is amphoteric, it can be colored by acidic or alkaline dyes, and extraction can be used to identify synthetic and natural dyes [9].…”

Objective: The purpose of this study was to determine whether synthetic red dyes are present in red spinach samples. Methods:The presence of the dyes Ponceau 4R, Carmoisine, Rhodamine B, Amaranth was determined in red spinach using reactions, followed by paper chromatography and thin-layer chromatography (TLC)-densitometry. In paper chromatography analyses, analytes were eluted using n-butanolethanol-water (4:5:5) and isobutanol-ethanol-water (3:2:4), and in TLC-densitometry, analytes were eluted with n-butanol-ethanol-water (3:7:1). Results:No synthetic red dyes were found in the seven red spinach samples. Conclusion:The synthetic dyes Rhodamin B, amaranth, Ponceau 4R, and Karmoisin were not found as contaminants of red spinach.

“…Natural colours can be derived from fungi, minerals, animals, insects, and some plant components such as leaves, flowers, bark, roots, plant shells, fruits, and skins [8]. Apparently, they provide unusual, delicate colours that are pleasing to the eyes and radiate a sense of tranquillity and harmony with nature [9].…”

Global interest in dyeing fabrics using natural dyes has increased due to recent trends toward sustainable textiles. As opposed to synthetic dyes, colourants from natural dyes contribute to environmental preservation and reduce human dependency on hazardous resources. This study extracted colourants from Bandicoot berry (Leea Indica) or Memali (Malay), using the aqueous water extraction methods. Infrared (IR) and exhaustion (EX) dyeing were performed on 100% plain silk fabrics at 90℃ for 60 minutes with a simultaneous mordanting technique. The dyed fabrics were then measured using a spectrophotometer to analyse the L*a*b* values and K/S values of the shades obtained. The ability to withstand washing, perspiration, rubbing/crocking, and light of the dyed fabrics were compared. All fastness testing was done in accordance with MS ISO Standard and AATCC. The K/S values of the dyed fabrics were enhanced using mordants. The fastness properties of the IR-dyed silk fabrics gave ratings from good to excellent compared to EX-dyed fabrics which received mostly fair to good ratings. To conclude, this study provides empirical evidence that the colour properties of dyed silk fabrics with natural colourants extracted from Bandicoot berry (Leea Indica) can be optimized by using IR dyeing.
