Eco-dyeing of wool yarn with Ziziphus jujuba Mill. (Ber) and its colour fastness properties

Abstract

In search of eco-friendly processes for dyeing with natural dyes research has been focused on identification and standardization of natural dyes. Considering the growing importance of natural colourants all over the world, the present work was undertaken with on aim to study the colour fastness properties of wool yarn dyed with bark of Ziziphus jujuba Mill. (ber). The dyed wool samples had good to excellent colour fastness to washing, crocking perspiration and sunlight. Different shades of brown colour of rust, candy pink, biscuit brown, nut brown and light brown were obtained using different mordants. This type of eco-dyeing process may be helpful in increasing the variety of colours in the field of textiles.
