Optoelectronic Properties of Natural Cyanin Dyes
The Journal of Physical Chemistry A, 2009An integrated theoretical/experimental study of the natural cyanin dye is presented in terms of its structural and optoelectronic properties for different gas-phase and prototypical device configurations. Our microscopic analysis reveals the impact of hydration and hydroxylation reactions, as well as of the attached sugar, on ground and optically ...

Sustainable Dyeing of Silk with Natural Dyes Using Natural Sources of Water
Journal of The Institution of Engineers (India): Series E, 2020River water containing different types of metals and heavy metals are far more efficient in promoting surface colour strength and all round colourfastness properties of silk fabrics when dyed with aqueous extract of Ceriops decandra and Diospyros malabarica. However, pre-mordanting with aluminium and/or ferrous sulphate would promote the depth of shade

Sustainable Dyeing of Wool by Natural Dyes in Conjunction with Natural Mordants
2021Indians are known as precursors in natural dyeing art. Even though home-grown knowledge mode has been experienced in the past over the years but applications of natural colourants have been reduced due to lack of methodical knowledge of extraction, dyeing procedures and documentation over generations.

Unconventional Natural Dyeing Using Microwave Heating with Cochineal as Natural Dyes
Research Journal of Textile and Apparel, 2011This research concerns making wool fabrics with dye extracted from cochineal using microwave heating. The result shows good fastness properties. To promote value addition in domestic processing and to boost rural income and employment in small-scale agroenterprises, it is necessary to promote non-polluting natural dyes, which involve inexpensive ...
