The Colour Characteristics of Wool Dyed with Plants of Latvia

Aina Bernava

Abstract


Dyeing with natural dyes from plant and other
organic sources is known since the prehistoric times. In Latvia,
natural dyes have been used for the colouring of natural fibres,
such as flax, wool, cotton, silk and leather. Plants for the dyeing
were collected in autumn in Latvia, used fresh or dried. Mordant
ferrous sulphate, copper sulphate pentahydrate, potassium
hydroxide, potassium dichromate and acetic acid were used
before, during and after dyeing. The quality of dyeing was
evaluated using the RGB system.
