Novel experimental techniques have been used to show that in thermofix dyeing disperse dyes are transferred from cotton to polyester fibres—in a blend or union fabric—solely by a vapour‐phase mechanism. Other possible modes of transfer were examined, but no evidence was found to support them. The heat fastness of paniculate disperse dyes on cotton was correlated with their transfer properties to polyester fibres. The various types of behaviour of disperse dyes in bulk application are explained. Functions of padding assistants and, in particular, a migration inhibitor and the importance of time and temperature in thermofixation procedures are dealt with in practical terms in Part II of the paper.
