A theoretical study of dye‐fibre interactions leads the colour chemist to the conclusion that disperse dyes offer potential as the universal dye for all fibres; the requirement is to incorporate the necessary dye sites covalently within these fibres either as a pretreatment or ideally during the dye application process. The types of disperse dye sites required and their effect on dye colour yield and wet fastness are reviewed. It has been found that a minimum number of disperse dye sites must be incorporated into cellulosic and protein fibres in order to achieve the appropriate quality of coloration. This paper thus studies a water‐based method to benzoylate cotton cellulose in order to improve its disperse dyeability. Clearly commercial interest in these basic studies will be in the fields of single‐dye blend dyeing and printing (e. g. wool/polyester, cotton/polyester, wool/cotton, cotton/silk, etc.) and some initial results in these areas are reported.
