摘要
研究了双活性基活性染料对改性维纶基牛奶纤维织物的染色工艺;讨论了硫酸钠用量、碳酸钠用量、染色温度及固色时间对活性染料上染百分率及固色效率的影响并得出较佳染色工艺;测试了阳离子改性剂HSQA改性后织物的染色牢度并与未改性织物比较,研究发现:改性后汽巴克隆红FN对维纶基牛奶纤维织物的上染百分率、固色效率得到提高,硫酸钠用量大大降低,甚至可不加,缩短了染色时间,提高了染料利用率,节约染料用量近40%.改性维纶基牛奶纤维织物具有良好的耐水洗色牢度,摩擦色牢度与未改性样相比下降1级.
The dyeing of vinylon-milk protein fabric with two bi-functional reactive dyes was studied. The influences of Na2SO4 dosage, Na2CO3 dosage, dyeing temperature and fixation time on the dye uptake of reactive dyes were discussed, and the optimal dyeing process was obtained. The color fastness of fabric modified with cationic modifier HSQA was measured and compared with the control sample. The results showed that the dye uptake, fixation rate of Cibacron Red FN on modified vinylon-milk fabrics were improved. The dosage of Na2SO4 was greatly declined, and even without adding. The dyeing time was shortened, and the dye availability was improved, nearly 40% of the amount of dyes was saved. The modified vinylon-milk fabric had good washing fastness, however, the crocking fastness decreased 1 level compared with the controlled sample.
