The results obtained from the experiments on dyeing equilibrium of cyanoethylated cellophane-congo red system are as follows. 1. Change of the degree of cyanoethylation of cyanoethylated cellophane has no influence on the form of adsorption isotherm of congo red by cyanoethylated cellophane; it always shows FREUNDLICH type. 2. The amount of dye adsorbed by cyanoethylated cellophane tends to rise with the increase of the degree of cyanoethylation, but decrease on over 24 mol. percent of the degree of cyanoethylation. The above-mentioned phenomenon can be explained as follows; the micelle structure of cellophane goes loose through the introduction of hydrophobic group in cellulose molecular by cyanoethylation, hense the increase of the adsorption seats of dye stuffs. 3. Due to the previous report and these experiments, it is concluded that the optimum degree of cyanoethylation of cellophane is about 9 mol. percent at practical dyeing.
