Notes Upon Indigo

"Notes Upon Indigo" by John L. Hayes is a scholarly treatise on the significance of indigo as a dyeing material and its implications for the textile industry, written in the late 19th century. The work not only discusses the properties and history of indigo but also delves into its cultivation, commercial importance, and dyeing processes. Hayes aims to advocate for the use of indigo in American textile manufacturing to elevate the quality of dyed fabrics and enhance the market reputation of American goods. The opening of the treatise introduces the reader to Hayes' meticulous exploration of indigo, emphasizing its stability in color as a desirable trait for dyed fabrics, particularly wool and cotton. He contrasts the traditional use of indigo with the recent trend toward less stable, synthetic dyes, arguing that this shift compromises fabric quality. Hayes provides historical context regarding the international trade of indigo, its cultivation modes, and practical applications in various dyeing processes. He stresses the need for American manufacturers to embrace more time-tested and reliable methods of dyeing to improve their industry standards and consumer satisfaction.
