Top 11 Best Dye Yielding Plants in Nepal
Want to know the best dye yielding plants?
The dye is a water-soluble substance and it is used to color textiles, fibers, leather, and other materials. By reaction and absorption process, they form chemical bonds with the substance to which it is being applied.
Dye has two types: Natural and synthetic. The natural dye can be obtained from various plant species by crushing their pigment-containing parts like berries, fruits, roots, bark, leaves, and flowers.
There are three groups of natural dye: Indigo, Cochineal, and Ocher. But the synthetic dye has various types: Acid dyes, basic dyes, direct or substantive dye, mordant dye, vat dye, reactive dye, disperse dye, and azoic dye.
