Abstract

Turmeric Curcuma Longa is a perennial herb from ginger family, Zingiberaceae. It is native to southern Asia, requiring temperatures between 20 and 30 -°C (68 and 86 -°F) and a considerable amount of annual rainfall to thrive. Rhizomes of turmeric are used for extracting yellow dye for food and clothing. The present study was conducted at Department of clothing and textiles, G B pant university of Agriculture and Technology to develop 100% natural yellow colour for dyeing of wool without the use of any synthetic materials as mordants. Wool yarn was dyed with Turmeric at various concentrations, time durations and temperatures using different methods of dyeing. Different variables standardized were; Method of dyeing, concentration of dye material, temperature for extraction, temperature for dyeing, time for extraction and time for dyeing. The dyed samples were evaluated for colour fastness to light and washing as per ISO standards at the Department of textile technology, IIT Delhi.
