Previous attempts to modify the dyeability of cellulosic fibres for anionic dyes by pretreatment with reactive quaternary agents are discussed critically. Agents of the epoxypropyl type are compared with those of the chlorotriazine type and experimental investigation of their mode of action is reported, with particular reference to the preparation and evaluation of two classes of chlorotriazine‐type quaternary agents. Comments are made on the possible mechanism of dyeing of cotton modified by pretreatment in this way. It is concluded that the ideal method of quaternising pretreatment for enhancing the dyeability of cellulose has not yet emerged.
