纤维素纤维织物活性染料无尿素印花工艺
|
摘要
全料法活性染料印花工艺需要使用大量尿素,成为最主要的氨氮排放来源。活性染料无尿素印花技术采用助剂T替代尿素,大大降低了印花废水的含氮量。研究了助剂T的性能及其对纤维吸湿性和印花糊的影响,优化无尿素印花工艺,测定印花织物色深、色光、固色率及色牢度,并与传统尿素印花进行比较。结果表明,助剂T用量为5.0%时,可实现棉织物活性染料无尿素印花,减少氨氮排放60.0%。
The full-material reactive dye printing process required a large amounts of urea, which becomed the most main source of ammonia nitrogen emissions. The reactive dye-free urea printing technology, using the additive T instead of urea, greatly reduced the nitrogen content of the printing wastewater. The properties of the additive T and its influence on the hygroscopicity of the fiber and the printing paste were studied. The urea-free printing process was optimized, and the color depth, color light, fixing rate and color fastness of the printed fabric were measured and compared with the traditional urea printing. The results showed that when the amount of the auxiliary agent T was 5.0%, cotton fabric reactive dye-free urea printing could be obtained, and the ammonia nitrogen emissions were reduced by 60.0%.
