摘　　要：将叔胺类化合物烟酸用于一氯均三嗪型活性染料中性浴上染真丝绸,探讨了烟酸用量、染色温度、染色时间及电解质浓度对上染率和固色率的影响。结果表明,加入烟酸能提高活性染料在真丝绸上的固色率,在最佳催化染色工艺条件下,染色织物的各项牢度指标均符合服用要求。同时催化染色工艺能缩短染色和固色时间,具有节省能源,染后丝纤维受损小的优点。Nicotinic acid was used as a catalyst in neutral--bath dyeing of silk with monochlototriazine reactive dye and the effect of nicotinic acid amount, dyeing temperature, dyeing time and concentration of electrolyte on exhaustion and fixation was discussed, respectively. The results indicate that by using nicotinic acid, fixation of monochlorotriazine reactive dye on silk fabric can be improved and sound fasmess of the dyed fabric treated under the optimal condition can also be achieved. Moreover, catalyzed dyeing reduces the dyeing and fixing time and is beneficial to saving the energy and decreasing the loss of fabric strength.
