  Abstract

When sodium alginate paste and filter paper containing disperse dye were fixed by high temperature steaming (HTS), the diffusion behaviors of disperse dye to PET film from print paste or filter paper were investigated by film-roll method and the diffusion equation of semi-infinite medium. By HTS at 170−190℃ for different fixing times, dye uptakes and the diffused distances were increased and the differences of dye uptakes between each layers of PET film-roll were decreased with elevating temperature and fixing time, which resulted in the large increases of diffusion coefficients. In the case of print paste, compared with filter paper, relatively large amounts of diffused dye occurred to increase both the dye uptakes of layers and the differences of dye uptakes between each layers, which caused the decreases of diffusion coefficients. The apparent activation energy obtained from the diffusion coefficients of dye to PET film from print paste was 30.9 kcal/mol, and that from filter paper was 26.0 kcal/mol.
