Uses of eco-friendly natural dyes and auxiliaries in textile printing

Natural dyes which were ignored during last sixty years into background by synthetic dyes, are recently again becoming object of consumer interest due to awareness of possible risks arisen by synthetic dyes. These days the consumer interest towards natural dyes is increased because natural dyes are eco-friendly and non-toxic in the nature. Although, ecological awareness among the public has led to a renewed investigation of natural dyes, a lot of work has been carried out for dyeing of textiles using natural dyes but the work on printing is very limited. This paper provides extensive literature information about the natural dyes, mordants and thickeners used for textile printing.
