Reactive Dyes: Types, Classification & Structure Meghmani

WebReactive dyes develop bright shades with good wash, light and perspiration fastness properties due to its reaction with ─NH 2 group of silk. Silk should be thoroughly degummed before dyeing to remove sericin completely which may otherwise react with dye to show poor wash fastness. Silk can be dyed in either of alkaline or acid methods. WebColour fastness is the property of dyes and it is directly proportional to the binding force between photochromic dye and the fibre. The colour fastness may also be affected by processing techniques and choice of chemicals and axillaries. [1] [2] The term is usually used in the context of clothes.
