Abstract
Schizandra is a mature fruit of Fructus Schisandrae Chinensis. The wool fabric was dyed with a natural schizandra dye. The adsorption kinetics and thermodynamics of using mordant and direct dyeing technology were studied. The influence of dyeing time and temperature on wool fabric were explored. The research result shows that the adsorption kinetics of schizandra dye on wool fabric meet the pseudo second-order kinetic model and the rate constant k2 indicated a faster adsorption rate of mordant dyeing than for direct dyeing. The negative value of ΔG validated the feasibility of the sorption process, and the sorption of schizandra dye on wool fabric is spontaneity, whichever the dyeing method is direct dyeing or mordant dyeing.
