Development of a New Isotherm Model to Describe the Equilibrium Sorption of NonionicDyes by Semicrystalline Polymeric Fibers

One of the most important aspects of physical chemistry of dyeing is the description as well as theexplanation of the equilibrium sorption behavior of dyes by textile fibers. Because of the complex fine structureof textile fibers, having a single universal isotherm model to describe the dye sorption behavior of thesesubstrates remains unsolved. In this work, a new isotherm model to describe the equilibrium sorption of dispersedyes by semicrystalline polymeric fibers, based on the modification of the well-known Dual-mode sorptionisotherm model, is developed.
