摘要
在乙醇/水体系中用棉用活性染料黑B对羊毛织物进行染色,分析了乙醇体积分数对活性染料黑B染色后羊毛织物K/S值的影响,研究了活性染料黑B染色动力学并优化了羊毛织物乙醇/水染色工艺。实验结果表明,当体系中乙醇体积分数为80%时,羊毛织物染色后的K/S值达到最大;在乙醇/水(乙醇体积分数为80%)体系中,温度越高,活性染料黑B的扩散系数越大、半染时间越小。优化后的活性染料黑B乙醇/水染色工艺不仅染色后羊毛织物的匀染性提高,而且各项性能均达到常规水浴染色效果。
The effect of ethanol volume percentage on reactive black B and the kinetic parameters of reactive black B in the dyeing system were discussed. Results showed that the K/S reached the maximum value in the volume percentage of ethanol 80%. The higher the temperature in ethanol/water (the volume percentage of ethanol 80%) system was, the greater the diffusion coefficient of reactive black B was and the smaller the half-dyeing time was. The optimized dyeing process of reactive black B in ethanol/water system not only improved the levelness of wool fabric after dyeing, but also achieved the effect of conventional water bath dyeing.
