• Recent Advances in Disperse Dye Development and Applications by Alan T. Leaver, Brian Glover and Peter W. Leadbetter (Textile Chemist & Colorist, January 1992). The commercial development of new disperse dyes for 100% polyester and polyester/cellulosic blends is reviewed.
• Recent Advances in Wool Dyeing by Martin Bide (Textile Chemist & Colorist, May 1986). Like all other segments of the textile industry, wool dyeing has changed dramatically in the last two to three decades. Developments in chemicals, machinery, and methods have opened new possibilities and solved some old problems.
• Red Pigment of the Imagination Produced at New Ciba Plant by Susan H. Keesee (Textile Chemist & Colorist, August 1997). Ciba to produce a red pigment based on diketo pyrrolo pyrrol chemistry.
• Reducing Pollution and Energy Requirements in Cotton Dyeing by Peter J. Hauser (Textile Chemist and Colorist & American Dyestuff Reporter, June 2000). A process using cationically modified cotton can reduce pollution and energy requirements associated with dyeing cotton with direct and fiber reactive dyes.
• Research on Treatment of Dye Waste by D. L. Michelsen (Textile Chemist & Colorist, March 26, 1969). As the use of man-made fibers, especially polyesters, continues to increase, the problem of disposing of disperse dye wastes become more serious. This paper discusses methods of dye waste treatment under study at Virginia Tech.
• Synthesizing Premetallized Acid Dyes Based on Environmental Considerations by H. S. Freeman, J. Sokolowska-Gajda, A. Reife, L. D. Claxton, and V. S. Houk (Textile Chemist & Colorist, February 1995). A group of premetallized iron complexed monoazo dyes were synthesized as potential alternatives to presently used high volume chromium and cobalt containing monoazo acid dyes for nylon and wool.
