Colorimetric Analysis to Study the Dyeing Behaviour of Jute Textiles Using Selective Synthetic and Natural Dyes

Abstract

Jute, being a lignocellulosic bast fibre, is dyed with different classes of dyes such as direct, reactive, vat and sulphur which are also used to dye other cellulosic materials such as cotton and viscose. In addition to these, it is possible to dye jute with acid, basic and pre-metallized dyes due to the presence of lignin and gluconoric groups of hemicellulose. Here, a review of the dyeing of jute is done to analyse the dyeing properties of jute fabrics dyed with three classes of synthetic dyes – direct, reactive and acid dyes along with some selected anionic natural dyes. The dyeing process variables, colour strength values and colour fastness properties were analysed and elaborated. The studies have focused on some comparative assessment of the dyeing properties using different synthetic dyes and natural dyes too. The dyeing properties and colour fastness properties of synthetic-dyed and natural-dyed jute materials are also discussed and analysed in detail showing colourimetric analysis and their results.
