Eco-friendly Sustainable Dyeing of Tencel Textiles with Plant-Based Bio-Mordant Using Dewberry Fruit Extract as a Source of Natural Dye

Abstract

Natural products extracted from plants with excellent dyeing properties are widely explored due to greener and sustainable dyeing methods. The current study is concerned with applying natural dye extracted from dewberry fruit by using T. chebula (black acacia) and A.mearnsii (myrobalan) as a source of bio-mordant. The results proved that dewberry fruit extract could be an excellent natural dye source for the coloration of tencel and other cellulosic textiles. Using bio-mordants like T.chebula and A.mearnsii has improved the color properties, producing vibrant shades of color with high color strength. The color fastness ratings tested by ISO standards showed improvement after using bio-mordant. Additionally, using the AATCC 100–1999 (The American Association of Textile Chemists and Colorist) test methodology, the bio-mordanted tencel samples showed excellent bacterial reduction against S.aureus and E.coli bacteria. Hence, it is concluded that the dye extracted from dewberry fruit has huge potential to impart color on tencel fabric, producing vibrant shades of color and making the dyeing process greener and sustainable using bio-mordants.
