采用不加分散剂的一浴法染色65：35涤棉混纺织物，得到了一系列基于2-羟基吡啶-6-酮的1-取代基活性分散染料。研究了这些染料在涤棉织物及涤棉混纺织物上的染色性能。在涤棉混纺织物上，染料的得色率与初始pH高度相关，最佳pH值为5。除耐晒牢度适中外，共混物具有良好的匀染性和良好的至极好的牢度性能。
A series of temporarily solubilised reactive disperse dyes based on 1-substituted derivatives of 2-hydroxypyrid-6-one were applied to a 65;35 polyester/cotton blend using a one-bath dyeing method without dispersing agent. The dyeing behaviour of these dyes on polyester and cotton fabrics, and polyester/cotton blend fabric, were studied. The colour yields of the dyes on the polyester/cotton blend were found to be highly dependent on the initial pH, optimum results being obtained at pH 5. Good levelling and good to excellent fastness properties were obtained on the blend, with the exception of lightfastness, which was moderate.
