摘要：The synthetic dyes which are of wide commercial importance cause severe atmospheric and environmental pollution. Use of natural dye has increased several folds in the past few years due to ecofriendly approach of the people.The present investigation was carried out for dyeing with natural dye obtained from flowers of Tecoma stans belongs to bignoniaceae family, commonly knows as Ginger Thomas. The trumpet-shaped flowers are clustered at the branch tips. The individual flowers are broadly tubular, 2 inches (5 cm) long, and have 5 rounded lobes. The flowers are followed by 8 inch (20 cm) long, narrow, brown seed pods. In the present study, scoured cotton fabric was dyed with chemical and natural mordants . Dyeing was carried out by pre-mordanting, post mordanting and simultaneous mordanting. The dyed samples have shown good washing, light and rubbing fastness properties. The production cost of the Tecoma stans flower dye was estimated.
