Natural Dyes
- Natural dyes are a class of colorants extracted from
vegetative matter and animal residues.
- There are many plant materials that
can be used for dyeing yarns and materials: roots, bark, leaves,
berries, seeds, twigs, branches, tubers, and nut hulls, each capable
of producing a range of colors with various mordants and yarns. In
addition, when
properly applied, natural dyes are fast, resisting fading due to
exposure to sunlight.
- Natural dyes were used to color clothing or other textiles
- Use of natural dyes cuts down significantly on the amount of
toxic effluent resulting from the synthetic dye process.
- Natural dyes generally require a mordant, which are metallic
salts of aluminum, iron, chromium,
copper and others, for ensuring the reasonable fastness of the color
to sunlight and washing.
- Most of the natural dyes produce comparatively dull shades
- Larger growth is expected in the natural colorants market for
food, drugs and cosmetics (FD&C) where certain dyes, such as carmine
and
annatto, are used regularly. Smaller amounts of natural dyes are
also used in coloring paper, leather, shoe polish, plastics and
paints.
- The US and Europe import market supply of natural dyes is
dominated by Mexico.
- Commercial indigo is sourced from both Mexico and India.
- Lac, cutch, barberry, kamala, tesu and dolu are all primarily
sourced from India, and cochineal and annatto seeds come mainly from
Peru.
- Quality standards for natural dyes vary widely, so it is
necessary to first contact an importer to find out what they are
looking for.
- Mordants are chemical additives that sometimes help a fiber
accept a dye that it might otherwise reject.
