Lesson 01 : Facts About Dyes

Definition Of Dye

• Dyes are natural or synthetic substances that add colour to the fibre, yarns and fabrics. Dyes may combine chemically with fibre molecules, attach themselves to the fibre surface, or be absorbed in to the fibre without the chemical action.
• The molecules of the organic compounds called dyes are responsible for the colour of the dyed and printed textile fibre materials.
• Dye is a compound that can be fixed on a substance in a more or less permanent state and evokes the visual sensation of a specific colour.
