Quantitative evaluation for the ordered adsorption state of rigid molecules on fiber surface was investigated. Fiber employed was cuprammonium regenerated cellulose hollow fiber, BMM35^<[○!R]> whose mean pore size was 35nm. Carbon tetrachloride was selected as an isotropic solvent for the sample immersing, and C. I. Disperse Red 1 was applied for rigid molecules. Characteristics of orientation for the adsorbed molecules were evaluated by the interference color method in which we observed interference colors as a function of the position from the wall surface of a hollow fiber in a solution through polarization microscope under the cross nicols and converted the interference colors to retardation Γ, and then the contribution of the adsorbed molecules in Γ was provided by the difference in the values of Γ between in carbon tetrachloride and in the solution. The interference color method was confirmed by the dichroism with polarized light ultraviolet visible spectrophotometer.
