Abstract

The article comprehensively reviews recent breakthroughs in use of newer types of natural dyes for improvement of the properties. The dyeing of silk fabric has been done using four types of natural dyes that include indigo, turmeric, madder and Terminalia Cebula. The parameters evaluated include color measurement, light fastness, wash fastness and rubbing fastness. There has been improvement in properties. In another innovative research, dyeing could be done with and without mordants. In another innovative research, silk fabrics have been mordanted with alum and dyed with cochineal and gall oak shellac extracts. Optimum dyeing parameters have been determined by using different concentrations of these natural colorants.
