摘　　要：将3支以2,4-二氨基苯磺酸为偶合组分的双偶氮活性染料(YDY-1、YDY-2、YDY-3)用于棉织物的印花,考察了印花工艺条件对印花织物色深的影响和各项色牢度性能。结果表明:3支活性染料YDY-1、YDY-2、YDY-3具有较好的印花工艺宽容性,蒸化时相对湿度可低至55%,蒸化时间2~3min,小苏打用量可低至1.0%,与尿素用量为5.0%相比,当不使用尿素时,染料YDY-1、YDY-2、YDY-3印花织物相对色深分别增加了4.8%、7.2%和1.3%;染料YDY-1、YDY-2、YDY-3在棉织物上的印花固色率分别为71.1%、74.3%和77.2%;变色牢度和沾色牢度都为4~5级,干摩和湿摩分别都达到4~5级和4级,耐日晒色牢度达到3级及以上。Three diazo reactive orange dyes(YDY-1-YDY-3)with 2,4-diaminobenzenesulfonic acid as coupling component were used in the printing of cotton fabric.The effects of printing conditions on the color depth,and color fastness of cotton fabrics printed with these dyes were investigated.The results show that the reactive dyes possess wide process compatibility.The relative humidity can be as low as 55%,the steaming time is 2-3 minutes and the alkali dosage can be as low as 1.0%in the printing.Compared with 5.0%dosage of urea,the increment of relative color depth of cotton fabrics printed with Reactive dyes YDY-1-YDY-3 is 4.8%,7.2%and 1.3%,respectively,when the urea is not applied.The fixation of the reactive dyes YDY-1-YDY-3 is 71.1%,74.3%and 77.2%,respectively.The color fastness to color change and staining of the three reactive dyes can reach grade 4~5.The dry-wet rubbing fastness can reach grade 4-5 and grade 4,respectively.The light fastness is more than grade 3.
