Studied adsorption-equilibrium of silk, wool, polyester and nylon Fabricsadsorbing Nature identical dye Alizarin. The results show that the kind of adsorptionbelongs to Nernst adsorption, adsorb corresponds to distributing mechanism. Alizarin hasdisperse dye's characters. Meanwhile, Standard affinity, dyeing enthalpy and entropy ofAlizarin for four fabrics were calculated.
