Experience in dyeing indigo with foam in a cooperative IMD Corporation/Gaston Systems Corporation/Texas Tech University project prompts the desire for exploring the application of other dye classes with foam. Positive commercial results have already been achieved with reactive dyes. Potential for vat and sulfur dyes achieving gains in economy, fastness, control, and environmental impact can be extrapolated from the cooperative foam indigo experience. The commercial state of this concept and the opportunities for research are discussed.
