The effect of poly(ethyleneimine) (PEI) on the adsorption and desorption of lac dye (Natural dye 25; CI 75450) on cotton fibres is reported. We show that PEI increases the dye adsorption and decreases any subsequent desorption of lac dye from the cotton fibres. At equilibrium, the ratio of the numbe...
