Simultaneous dyeing and finishing of wool and natural silk fabrics using Azolla pinnata extract

Chemically Modified Extract of Peanut Red Skin: Toward Functional Dyeing of Textile Fabrics and Study Adsorption Kinetics and Adsorption Isotherm of Dyeing Process

“…Natural colorants are gaining popularity due to their nontoxic and environmentally beneficial properties. ,− There are numerous sources of color that may be extracted from plants, animals, and insects, and these sources can be used in a variety of ways to dye textiles. ,− Comparing the cost of production, getting dyes from waste and byproducts would be better than harvesting directly. ,,− However, there are drawbacks and difficulties in using natural colorants for dyeing textiles. ,− These include their inherent shortcomings, which have limited their potential for industrial use, , the lower yield and color fastness, mordant and other chemical requirements, and little to no attraction toward the textile substrate. − Also, using metallic mordants in the dyeing process increases the effluent burden because they do not exhaust in a residual dye bath. ,, …”

Valorization of Sulfonated Kraft Lignin as a Natural Dye for the Sustainable Dyeing of Wool Fabrics: Effect of Peroxide Oxidation

“…Mostly, tannin and other polyphenols extracted from barks, leaves, flowers, fruits, and fruit skins were studied for the dyeing of wool. Tannins extracted from barks of various plants, including Ziziphus, cinnamon, walnuts, Azolla pinnata extract, and Cassia reingera, were found suitable for the dyeing of wool fiber. Natural dyes extracted from leaves of pomegranate, Berberis thunbergia, hibiscus flowers, Hibiscus rosa-sinensis, Crocus sativus, skins/peel of Citrus sinensis L., and various fruits, including myrobalan, chamomiles, and peanut shell, are also studied as an alternative to synthetic dyes.…”
