A Collection of Naturally Dyed Wool Yarn
The natural dyes are ecological and ethically produced. These dyes have been proven safe and durable during centuries of use.
Alum, a non-toxic mordant, is used to fix the colors.
Indigo dyeing begins with the extraction of indigan from the leaves of Indigoferia Tinctoria or Central American Indigofera Suffriticosa. The water soluble indigan will then be oxidized to form the actual indigo pigment. The indigo pigment is not water soluble, therefore the dyeing process requires first a reduction and then the oxidization of the pigment, when the blue colour becomes visible. This process is more demanding than the other natural dyeing methods using mordants, and is done separately.
Aurinkokehrä yarns are dyed with Mexican Fair Trade -labeled indigo.
The latin name Reseda Luteola refers to Luteolin, a very potent and durable dyestuff the plant contains. This plant has been widely cultivated for dyeing purposes for centuries. Combined with indigo, weld produces bright and vibrant shades of green.
Lac is pruduced by the insect called Laccifer Lacca. The females of the species conquer a tree as their home, where they secrete a resin from which the dyestuff is separated. In addition to color, the resin can be used to make shellac that is used to polish furniture.
Madder comes from the roots of the Rubia Tinctoria plant. Madder dyes warm shades of red and orange.
The bright cold shades of red come from the Cochenille insect, lat. Coccus Cacti, that live on the leaves of a cactus plant. The species is native to Southern America, and is commercially cultivated for dyestuff production. The biggest user of cochenille nowadays is the cosmetic industry.
