Azadirachta indica Mediated Bioactive Lyocell Yarn: Chemical and Colour Characterization

Abstract

The study deals with preparing aesthetic textiles using methanolic extract of Azadirachta indica leaves. The extract with metallic and natural mordents was utilized to create various shades on lyocell yarn using exhaust technique of dyeing. Aesthetic values of dyed yarns were analyzed in terms of colourimetric parameters, that is, CIE L * a * b * and colour fastness. The attachment of Azadirachta indica compounds has been confirmed by using infrared spectroscopy (IR) analysis. The dyed samples exhibit moderate to good fastness properties. The study showed that lyocell yarn treated at 15% (owf) methanolic extract of Azadirachta indica leaves can be utilized as effective bioactive textiles. Azadirachta indica is an alternative to synthetic antimicrobial agents. This bioactive yarn can be used in fashion as well as in medicinal industry.
