【摘要】 研究了聚酯超细纤维的染色动力学和热力学,主要包括不同线密度纤维的上染速率、半染时间、扩散系数、平衡吸附量、亲和力、染色热和染色熵等参数。同时对超细纤维的显色性和提升性与普通纤维进行了比较。分析了超细纤维不同于普通纤维的原因。更多还原

【Abstract】 Dyeing kinetics and thermodynamic studies have been conducted on the polyester supermicrofiber. The rate of dye uptake, the time of half dyeing, diffussion coefficients, amount of equilibrium adsorption, standard affinity,enthalpy and entropy of dyeing have been calculated and discussed. Besides, the deep dyeing and build up of the supermicrofibers have been compared with the normal fiber. The reason why the dyeing properties of the supermicrofiber are different from the normal fiber has also discussed.更多还原
