摘要

The main aim of this contribution is description of the influence of the modifying component content on the dyeing characteristics of modified polyester (PET) fibers. The especially prepared copolyester fibers containing isophtalic acid (denoted by Kl), adipic acid (denoted by KA), salt of 5-sulphoisophtalic acid (denoted by KS) and polyethylene glycole having molecular mass 3000 (denoted by PG) have been prepared under comparable technological conditions. The dyeability has been characterized by means of dye concentration C_(90) after a dyeing of fibers for a period of 300 min at 90℃ and parameters of non-isothermal dyeing curve (rate constant, equilibrium concentration). The applicability of these parameters for description of dyeing differences caused by the presence of modifying components is discussed.
