The major factor producing the first reactive dye for cellulose was the belief that cellulose was a relatively inert substrate and that conditions required to effect a chemical reaction would cause serious fiber degradation. Therefore, in early studies dyestuff chemists were led astray in thinking that they needed to convert cellulose to the more reactive soda cellulose to make fiber reactivity possible. Yet, a large number of reactive dyes with varieties of reactive groups were eventually developed. A summary of the history of commercial reactive dyes for cellulosic fibers is shown in Table 1.
