Natural dyes are dyesor colorants derived from plants, invertebrates, or minerals. The majority ofnatural dyes are vegetable dyes from plant sources roots, berries, bark,leaves, and wood and other biological sources such as fungi andlichens.Archaeologists have found evidence of textile dyeing dating back to theNeolithic period. In China, dyeing with plants, barks and insects has been tracedback more than 5,000 years. The essential process of dyeing changed little overtime. Typically, the dye material is put in a pot of water and then thetextiles to be dyed are added to the pot, which is heated and stirred until thecolor is transferred. Textile fibre may be dyed before spinning (dyed in thewool), but most textiles are yarn-dyed or piece dyed after weaving. Manynatural dyes require the use of chemicals called mordants to bind the dye tothe textile fibres; tannin from oak galls, salt, natural alum, vinegar, andammonia from stale urine were used by early dyers. Many mordants, and some dyesthemselves, produce strong odors, and large-scale dyeworks were often isolatedin their own districts.MARKETOUTLOOK
