Taking into account the effect of optical density used to enhance the cross-sectional views of fibrous materials, a new preparative technique was applied to detect the skin-core structure of Cupra and Tencel filaments. The same samples were also examined to determine the characteristic concentration gradient of dye molecules along the fiber axis starting from the slices section. Microphtospectroscopic observation of Cupra and Tencel filaments shows that the diffusion rate is predominant factor at the initial stage of dyeing, and then an equilibrium state is attained depending on the fine structure of fibrous materials.
