Dyeing behavior of disperse dyes on KURARAY ESTER (KES), a polyester fiber containing methoxypolyethylene glycol (MPEG) as a co-monomer, was investigated.<br>As dyeing mechanism of disperse dyes on KES and polyethylene terephthalate fiber (PET) is due to the partition law, it is considered that the amorphous region plays a role as a solvent for the dyes.<br>Accordingly, it is proposed that the degree of amorphism of fiber should be introduced into T. G. Majury's equation as a correcting term to calculate affinity.<br>Increase in MPEG component results in the increase of affinity, heat of dyeing and diffusion coefficient, the decrease of entropy change (for convenience, the value in Fig. and table is shown as -ΔS° and activation energy of diffusion.<br>It is pointed out that this tendency is mainly due to the characteristics of configuration and rheological properties of the amorphous region.
