尿素替代剂XD-N在数码印花中的应用

Application of urea substitute XD-N in digital printing

采用尿素替代剂XD-N代替尿素,在真丝绸和棉织物上用爱普生活性染料和京瓷活性染料进行喷墨印花,测试了印花织物正反面的KZS值。结果表明,采用尿素替代剂XD-N 1%+尿素5%的工艺配方,不仅印花织物KZS值得到较大提升,而且还能使污水的氨氮值下降一半,具有生态环保的积极意义。

Using the urea substitute XD-N instead of urea for digital printing, the K/S values of the upper and back surfaces with the two reactive inks jetted through Epson nozzle and Kyocera nozzle are tested for silk and cotton fabrics. The results show that the color yield with the urea substitute XD-N 1% plus urea 5% can greatly enhance the K/S value of the prints, and the ammonia nitrogen content in the dyeing sewage is decreased by 50%, the process is environmental friendly.
