Abstract

The use of supercritical fluids (especially supercritical carbon dioxide) in the textile industry as a substitute to water-based dyeing processes has continued to be a subject of significant interest among researchers in recent years due to far reaching and promising contributions which have prompted their use in several areas. This chapter provides an in-depth and comprehensive review on the application of supercritical carbon dioxide for dyeing operations. The solubility of dyes in supercritical carbon dioxide, dye distribution, and mass transfer phenomena between the textile fibers and carbon dioxide are discussed while the challenges and limitations of supercritical carbon dioxide dyeing have been highlighted and suggestions proffered to address these problems.
