Fabrics - Vegetable Prints |
| Natural
dyes are dyes or colorants derived from plants, invertebrates,
or minerals. The majority of natural dyes are vegetable
dyes from plant sources-roots, berries, bark, leaves,
and wood-and other biological sources such as fungi and
lichens. |
| Typically,
the dye material is put in a pot of water and then the
textiles to be dyed are added to the pot, which is heated
and stirred until the color is transferred. Textile fibre
may be dyed before spinning ("dyed in the wool"),
but most textiles are "yarn-dyed" or "piece-dyed"
after weaving. |
|
Many natural dyes require the use of chemicals called
mordants to bind the dye to the textile fibres, tannin
from oak galls, salt, natural alum, vinegar, and ammonia
from stale urine were used by early dyers. Many mordants,
and some dyes themselves, produce strong odors, and large-scale
dyeworks were often isolated in their own districts. |
