The brightening effect of polyester fabrics with two disperse type dyes, i. e. the series of benzoxazol and naphtalimid in perchloroethylene containing a small amount of water has been investigated and compared with that in aqueous dispersion.
For both types of dye, we have found that the higher the dyeing temperature, the better the brightening effect over the range of 103-133°C.
It seemed that the addition of a small amount of water and also of dispersing agent did not particularly influence the brightening effect.
The brightening effect in perchloroethylene was far inferior to that in aqueous dispersion. This result may be attributed to the partition of each dye between the dye liquor and the fiber.
