Abstract

The dyeing properties of PET/dyeable PP blend fabrics were investigated with different types of disperse dye. The higher energy disperse dyes showed better build-up properties on both the PET and PP fibers and the dyeability gap between the materials was lower, especially at higher dyeing concentrations. Nevertheless, some color differences between the two materials were unavoidable. In terms of dyeing temperature, a higher dyeing temperature produced a bigger dyeability difference between the PET and dyeable PP due to the increased dyeing site capacity gap. The rongalite reduction clearing method showed a lower color yield in the PP compared with a conventional reduction clearing method using sodium hydrosulfite.
