Tencel is made by solvent spinning from a wood pulp solution dissolved in organic solvent, which is different in physicochemical properties from cotton and the regenerated fiber, rayon. In this investigation, the dyeing properties of Tencel for a direct dye were examined and compared with those of cotton and rayon. The initial adsorption rate of Congo Red (CR) for three cellulosic fibers at 40, 50 and 60℃ in descending order were: viscose rayon > Tencel (untreated) > cotton. The diffusion rate of CR into the fiber in descending order were: At 40℃, Tencel > viscose rayon > cotton; at 50℃, Tencel > viscose rayon > cotton; and at 60℃, viscose rayon > cotton > Tencel. The adsorption isotherm of CR on Tencel (treated with enzyme) was the Freundlich type. At a particular free dye concentration the equilibrium dye uptake at 70-90℃ was in the following order: Tencel > Cupra > cotton.
