Influence of Morphological Heterogeneity of Wool Fiber on Acid Dye Sorption

Abstract

The influence of applied surfactants on dyeing of wool with acid milling dye at low temperature considering its chemical and morphological heterogeneity is examined. The presence of nonionic surfactant molecules reduces surface barrier to dye diffusion into the fiber. Studies show that the intercellular regions and the low sulfur proteins of endocuticle should be considered as dye penetration route into wool fiber at initial stage of diffusion.
