摘要
以环境友好型的烟酸为催化剂,采用活性染料对真丝进行染色,比较了中性浴和弱碱性浴催化染色与常规染色的上染率和固色率。研究表明,中性条件下催化染色的固色率与常规碱性条件下染色相当,中性条件下催化染色可提高K型、KN型活性染料在真丝上的固色率,减轻废水污染,保护真丝的光泽和机械性能。中性条件下,活性红15在真丝上的吸附等温线符合Langmuir型;染色真丝具有良好的水洗牢度、干湿摩擦牢度及日晒牢度特性。
Reactive dyeing process of silk fabric with nicotinic acid as a catalyst is carried out , dye uptake and fixation in neutral and weak alkali conditions are compared with those of conventional dyeing process. Results show that fixation of neutral catalyzed dyeing is similar to that of conventional alkali process. Catalyzed dyeing under neutral conditions can impart silk fabric better luster and physical properties, as well as higher fixation with K type and KN type reactive dyes, therefore, burden on effluent treatment is lessened. The catalysed dyeing behaviour of C. I. reactive red 15 on silk under neutral condition confirms to a Langmuir type adsorption curve. The silk dyeings feature good fastness to washing, rubbing and sunlight.
