Abstract

Effect of various dyeing conditions on pure natural yellow dye from Turmeric for dyeing of wool yarn

Highlights

Synthetic dyes are produced at high temperature and pressure from chemicals isolated from petroleum derivatives
Turmeric is one of the oldest natural colouring agents used throughout the world from ancient times (Gulrajani M L)
It is cultivated in almost all the parts of India Curcumin is the prime principal constituent of yellow dye, along with other constituents like monodesmethoxycurcumin and bidesmethoxycurcumin, which contributes fewer amounts of pigment and flavour (GULRAJANI M L)

Summary

Introduction

Synthetic dyes are produced at high temperature and pressure from chemicals isolated from petroleum derivatives. During the manufacturing process of dyes many carcinogenic chemicals are used which leads to formation of toxic bi-products. These bi-products are discharged in the rivers, ponds or left in open. Cause severe atmospheric pollution (Paul R, 1996). This has threatened the ecological balance and called attention of the environmentalists to develop ecofriendly technologies to produce dyes from natural sources (Neelam Pruthi, 2007). The present study is aimed at developing 100% natural bright yellow colour for dyeing of wool without the use of any synthetic stuffs as mordants. Optimizing the dyeing conditions for turmeric dye, using simultaneous dyeing and extraction technique for dyeing of wool, investigated in the present study have not been reported earlier
