特深型活性染料染色性能研究

Study of reactive dye with deepest color dyeing performance

对特深型活性染料的染色特征值(SEFR)进行了测试,系统研究了染色工艺参数对SEFR值的影响规律.结果表明,特深型活性染料的染色特征值SEFR随染色工艺参数的变化规律基本与一般活性染料的变化规律相同,但特深型活性染料的E值和F值相对要高一些.另外,从染色效果和染色特征值的分析来看,特深型活性染料系列的匀染性和移染性较差.

The characteristic value （SEFR） of reactive dye with deepest color was tested, and the dyeing parameters influenced the characteristic value SEFR were studied. The result shows that the varied orderliness of the characteristic value （SEFR） of reactive dye with deepest color by dyeing parameters is the same as the common reactive dye, but the vale E and F of the reactive dye with deepest color are higher comparatively than other values. On the other hand,according to analyzing the effect on dyeing and the characteristic value of dyeing, the level dyeing and transferred dyeing of the reactive dye with deepest color are lower than other dye.
