Extraction of Dyes from Petrocarpus santalinus and Dyeing of Natural Fibres Using Different Mordants

Abstract

Aqueous extraction of natural dyes from Petrocarpus santalinus tree wood and dyeing of the following natural fibres: banana fibre, screw fine fibre, pineapple fibre, sisal fibre, korai and palm leaf using various mordants to fix the colour in the fibre materials were performed. Salt, sodium bicarbonate, oxalic acid, tannic acid, ferrous ammonium sulphate, stannous chloride (tin metal powder), alum and tamarind (Tamarindus indica) were used as a mordant for the dying of the natural fibres. Petrocarpus santalinus dye was effectively dyed on natural fibres using different mordants, producing different colours like tomato, maroon, orange red, chocolate, brown, quarry red, black, brick red, tile red, terra colla, sunbaked clay, gray, brick red, victorian red, firebrick, brown, crimson and orange, using these mordants.

Bio-mordants: a review

“…It is reported that with changing mordant and natural dye concentrations, several hues ranging from light to deep can be produced. In another study, Mariselvam et al ( 2018 ) used Pterocarpus santalinus tree extract as a natural dye and tamarind as a bio-mordant for dyeing natural fibers. It is stated that pale red-burgundy colors can be obtained in dyeings made using tamarind.…”

“…These dyes have been used for thousands of years to colour fabrics, yarns, and other materials [2]. Some examples of natural dyes include the following: plant dyes, which are obtained from various parts of plants, such as leaves, roots, bark, and fruits, examples of which include indigo (from the indigo plant), madder (from the madder root), and woad (from the woad plant) [3,4]; insect dyes, which are obtained from insects, such as cochineal (from the cochineal insect) and lac (from the lac insect) [5]; mineral dyes, which are obtained from minerals, such as ochre (from iron oxide) and azurite (from copper carbonate) [6,7]. Natural dyes are popular for their bright and long-lasting colours, as well as for the fact that they are non-toxic [8], eco-friendly [9], and biodegradable [10].…”
