Learning outcomes. At the end of this Topic you will be able to;

• Describe the fundamental aspects relating to cellulosic fibre, water, dye and inorganic electrolyte in relation to the coloration of cellulosic fibres using anionic dyes
• Discuss the hypotheses/theories/concepts in relation to the role played by inorganic electrolyte in the dyeing of cellulosic fibres using anionic dyes
• Differentiate between the theories put forward to the explain the action of inorganic electrolyte in the dyeing of cellulosic fibres using anionic dyes

This Topic relates to the specific dye-fibre combination anionic dyes for cotton and cellulosic fibres and is an enhancement to the information that is introduced within Topic 4.1.4.

The subject material that forms much of the content of this topic is prepared using information presented in the two referenced review papers, namely.

• Burkinshaw SM. The role of inorganic electrolyte (salt) in cellulosic fibre dyeing: Part 1 fundamental aspects. Coloration Technology, 2021:00:1-24.
• Burkinshaw SM. The role of inorganic electrolyte (salt) in cellulosic fibre dyeing: Part 2 theories of how inorganic electrolyte promotes dye uptake. Coloration Technology 2021:00:1-40.
