摘　　要：棉织物数码印花使用的活性染料墨水容易造成印花机喷头堵塞,产生打印断线的问题。对活性染料墨水的表面张力、黏度、含盐量、粒径等因素进行分析,结果表明:墨水的表面张力、黏度、含盐量均不会导致印花机喷头堵塞,墨水中存在的粒径超过5μm的不溶性杂质是导致堵塞的主要原因。活性染料印花墨水经离心分离除去5μm以上的不溶性杂质后,印花机喷头无堵塞问题,打印效果良好。The use of reactive dye ink in waterless digital printing of cotton fabric can easily cause clogging of the nozzle.Therefore,the ink parameters such as surface tension,viscosity,salt content and particle size of reactive dye ink that can cause above problems are analyzed.The results show that the surface tension,viscosity and salt content of ink do not cause clogging of the nozzle.Insoluble impurities with a particle size exceeding 5μm in the ink are the main cause of clogging.After centrifugal separation of insoluble impurities above 5μm,the printing process has no clogging problem and has good printing properties.
