Abstract
The continuing importance of blue denim maintains indigo as an important vat dye industrially. In this review, we examine the various methods that have been used in the past and are currently used to reduce and dissolve indigo for dyeing. We discuss recent insights into the bacterial fermentation technology, the advantages and disadvantages of the direct chemical methods that have predominated for the last century and potentially cleaner technologies of catalytic hydrogenation and electrochemistry, which are becoming increasingly important. With considerations of environmental impact high on the dyeing industry’s agenda, we also discuss the developments that have led to the production of pre-reduced indigo.
期刊介绍:
The primary mission of Coloration Technology is to promote innovation and fundamental understanding in the science and technology of coloured materials by providing a medium for communication of peer-reviewed research papers of the highest quality. It is internationally recognised as a vehicle for the publication of theoretical and technological papers on the subjects allied to all aspects of coloration. Regular sections in the journal include reviews, original research and reports, feature articles, short communications and book reviews.
