Natural Dyes:
The word ‘natural dye’ covers all the dyes derived from the natural sources like plants, animal and minerals.
Natural dyes are mostly non-substantive and must be applied on textiles by the help of mordants, usually a metallic salt, having an affinity for both the colouring matter and the fibre.
Natural dyes produce very uncommon, soothing and soft shades as compared to synthetic dyes.
Origins of Natural Dyes:
1. Plants & Vegetables
2. Animals & Insects
3. Minerals
4. Fungi ,Lichen & Mushrooms
