Introduction to Natural Indigo

To solve ecological and toxicological issues related to some synthetic dyestuffs, the potential application of a new thickening agent from wild taro corms and natural indigo dye in the screen print.

Background As one of the oldest traditional dyes, people worldwide have used natural indigo for centuries.

To improve the level dyeing property and colorfastness of natural pigment-dyed cellulose fiber, a study on the structure and properties of natural indigo spun-dyed viscose fiber was carried out systematically.

Themes of inquiry:• Understanding the naqsha harness for the Indian drawloom • Examining relations between textiles and architecture • Using symmetry analysis to recognize pattern repeats • Considering fashion in India, an evolving tradition • Learning about the revival of natural indigo in India • Observing craft traditions preserved through development and sustainability Our team: • Annin Barrett—textile artist and designer; instructor, fashion history and sustainable design • Carol Bier—curator, The Textile Museum (1984-2001); research associate (2001-2020); research scholar, Center for Islamic Studies, Graduate Theological Union • Anna Jolly—curator of textiles 1500-1800, Abegg-Stiftung, Riggisberg, Switzerland • Louise Mackie—curator emerita, Textiles & Islamic Art, the Cleveland Museum of Art, Royal Ontario Museum, and The Textile Museum • Barbara Setsu Pickett—associate professor emerita, Department of Art, University of Oregon.

Aeration or oxidation is one of the crucial steps during the plant-derived natural indigo dye production process.

This paper presents a comparative study on natural indigo and indirubin in terms of molecular structures and spectral properties by using both computational and experimental methods.

(Saccharomyces) cerevisiae strains to reduce natural indigo and to develop an eco-friendly reduction process of indigo as an alternative of chemical reductant.

The other motif, Pataruman, is derived from tarum plants whose leaves serve as natural indigo color.

In contrast, at a global scale, including in China, there has been a revival of interest in natural indigo use.

Natural indigoids such as indigo, woad, and Tyrian or shellfish purple served this purpose for millennia, but in the late 1800s synthetic analogs, in particular indigotin, quickly replaced natural sources.

For this purpose, we investigated the effect of pH condition on natural indigo (Indigofera tinctoria) reduction by yeast.
