As a preliminary study to an investigation of the feasibility of dyeing polyester/cotton blend by an all‐in process using a pH‐shift method, we have investigated the suitability of three types of conventional reactive dyes by considering the effects of pH and temperature on their hydrolysis and fixation behaviour. Monochlorotriazine, vinyl sulphone and bifunctional high exhaustion dyes were assessed but only the bifunctional reactive dye gave acceptable colour yield under the conditions likely to be employed during such a dyeing process.
