Full Description
Special Techniques of Natural Dyeing using Mordants and Modifiers explores the development of special auxiliaries that enhance the colourfastness, colour depth and sustainability of naturally dyed fabrics while maintaining a low carbon footprint. Key topics include chapters on mordants, bio-mordants, transitional metal salts and rare earth salts. Additionally, the book covers various modifiers and auxiliaries designed to improve colour adherence, as well as a chapter dedicated to post-mordanting treatments with amino compounds. Natural dye enthusiasts will gain valuable insights into using mordants sustainably and achieving vibrant, long-lasting colours from common flowers and other local vegetative materials.
