Instrumental characterization of merino wool fibers dyed with Cinnamomum camphora waste/fallen leaves extract: An efficient waste management alternative

Dyeing and printing Natural Fibers with Algae-Based Colorants

“…ΔL<0, indicates the existence of the color difference, in terms of higher intensity of the red color, when compared with the reference sample, as the obtained values range among -7,63 and -35,94. Similar results were obtained in different studies aiming at exploring alternative sources of red colorants for wool fibers dyed in mordanting conditions (Rather et al 2020).…”

“…The slight improvements obtained indicate the possible protection of this proteinbased chromophore. Comparing the fastness values with similar studies, focusing on alternative colorant sources, reveal alike results (Rather et al 2020) (Yusuf et al 2016), indicating that mordanted wool dyed with R-phycoerythrin is a plausible alternative for natural red textile coloration.…”

Valorization of Agro-industrial Waste from Peanuts for Sustainable Natural Dye Production: Focus on Adsorption Mechanisms, Ultraviolet Protection, and Antimicrobial Properties of Dyed Wool Fabric

“…The search for natural dyes and pigments is on the rise for use in the textile industry due to growing consumer demand worldwide. This surge is due to the eco-friendly, nontoxic, and environmental biocompatibility of the natural dyes. , The use of natural dyes has further gained utmost importance because of the allergic, toxic, and carcinogenic nature of azo and benzidine dyes. − In addition to traditional textile and food coloration properties, natural dyes from waste byproducts have been used to develop textiles with antimicrobial, antifungal, antioxidant, insect repellent, and deodorizing properties. − New functional properties such as being flame retardant have also been introduced via simple natural dye adsorption mechanisms under alkaline conditions, but a selected range of shades available on the market and their weak binding ability limit their use. This is mainly due to the poor shade reproducibility, nonstandardization of raw materials, and complexity of the process involved in natural dyeing processes. , An agricultural waste can be used to dye textiles if it is abundantly available, provides a sufficient dye yield, and possesses good fastness properties.…”

“…This is mainly due to the poor shade reproducibility, nonstandardization of raw materials, and complexity of the process involved in natural dyeing processes. , An agricultural waste can be used to dye textiles if it is abundantly available, provides a sufficient dye yield, and possesses good fastness properties. In this regard, the use of an efficient dye extraction technique with less energy and less time is a novel method for increasing the ecological sustainability of agro-industrial waste. , Of many agro-industrial wastes, peanut skin can be effectively explored for dyeing of wool textiles as it a rich source of polyphenols …”

Extraction of Tea Natural Dye and its Dyeing Properties on Cotton Fabrics

“…1,2 Due to the strict environmental standards to avoid the health hazards in textiles, the use of natural dye in textiles is growing rapidly. 3-5 The recent ban on the use of azo dye by the European Union has also increased the use of natural dye. 6 Tea natural dye, extracted from tea leaves is a kind of polyphenol compounds.…”
