天然染料等同体茜素的染色热力学研究

Study on Dyeing thermodynamic of Nature-identical Dye Alizarin

用天然染料等同体茜素对丝绸、羊毛、涤纶和尼龙等４种织物进行了染色的吸附平衡试验，结果表明：这４种织物对茜素的吸附属于Nernst吸附，符合分配机理，具有分散染料的特性．在所得试验结果的基础上，计算出了标准亲和力、染色热和染色熵．

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.
