Tutorial VII. Complete Guide to Dyeing Cellulosic Fibers
This is the seventh video tutorial in Michel Garcia's video course titled "From Plant to Dye."
The tutorial features Michel's lectures, demonstrations, and recipes.
This extensive video course offers over six hours of content, accompanied by detailed handouts and a recipe book.
The narration is in English, with subtitles available in English, French, Italian, Spanish, and German.
Fiber Plants and Plant Fibers
Michel tells about the main families of plant fibers: bast, leaf, seed and stalk fibers, about history, biology and chemistry of fibers.
Chemistry of cellulose
Why can't traditional mordanting methods for wool and silk be applied directly to cellulose fibers? And why doesn't soaking cotton overnight in alum or aluminum acetate lead to substantial aluminum ion accumulation?
Michel answers these and other questions.
Scouring of cellulose fabric
Michel shows a simple test for readiness to dye and gives recommendations for scouring cellulosic fibers
Aluminum acetate mordant, dry-and-fix method. Aluminum-Iron mordant
Demonstration and recipes. Special attention to middle-scale preparations. New recipe for Aluminum-Iron mordant!
Tannin and aluminum acetate, 2-step mordanting
Detailed recipe for 2-step mordanting of cellulosic fibers
Animalization: chitosan
Chitosan offers a fascinating alternative to traditional mordants, acting as a bridge between the worlds of textile dyeing and environmental sustainability.
Middle-scale mordanting with Al acetate
Demonstration and recipes, working with big pieces of fabric.
Dyeing with mordant dyes
Michel shows working with the main groups of natural dyes, in form of extracts ir raw plants.
