Natural dyeing is an ancestral know-how.
It is a tinctorial dye (their roots, berries, flowers, bark, leaves) or from mushrooms or lichens.
There are two types of fabrics:
- plant tissues that are cellulosic fibers (cotton, linen, hemp …)
- animal tissues that are protein fibers (wool, silk …)
Step 1: etching. Used to prepare the textile fibers to receive and fix the color.
Etching is done with tannins or metal salts (aluminum, iron …). There are colorless tannins (gallstones) or colored tannins (chestnut, myrobolan …).
Depending on the type of fiber (cellulosic or protein), the methods will differ. The cellulosic fibers like the double gauze that we use for our Furoma require a first step of packing to bring proteins to the fabric and a second step of aluning to bring alum which serves to fix the color during dyeing.
Etape 2 : dye bath Dyeing is done with dried and crushed plants or as a water-soluble extract. The temperature of the bath and the duration of the dipping depends on the fiber and the desired color.
