Bougainvillea Extract As Sustainable Natural Dye For Textile Dyeing

Abstract

The challenges in environment  are occurs due to harmful synthetic dyes.The use of these toxic and harmful synthetic dye shows great  interest in the use of natural  and  sustainable Colorants as alternatives for synthetic dyes. The Synthetic dyes, are always associated with toxic and hazardous effects in environment. They are water and air pollutants, and also have harmful effects to the human health. On the other hand the Natural dyes, are eco-friendly, biodegradable and they are derived from renewable natural sources. This study of sustainable colors will explores the potential of selected Bougainvillea plant bracts for dyeing. This plant is an ornamental plant which can grow in the tropical as well as in subtropical region. The selected bracts of Bougainvillea plants are rich in the pigments such as betalanin pigments. These pigments have ability to impart wide range of colour shades by using different mordants and dyeing methodds.The eco-friendly fabric such as Cotton and silk fabric was taken as sample and dyed by the Bougainvillea ruby red dye extracts.The mordants such as potash Alum, FeSO4, Banana stem sap and Myrobalan were used for fixation of this colour and to enhance bonding towards substrate. This dyeingng of fabrics gives variety of colour shades in presence of these mordants. The fastness properties of these dyeing process, suggesting that the Bougainvillea dye can be developed as economical natural dye source. The natural components are used for this dyeing work.
