摘　　要：为了提高颜料型数码印花墨水的品质,通过单一变量法对颜料黄74(P.Y.74)水相分散体的研磨工艺及其墨水物化性能进行系统研究,并应用于涤纶、棉、锦纶织物以及涤/棉混纺织物数码喷印。考察了分散剂种类与用量、消泡剂用量、研磨转速对P.Y.74色浆分散性能的影响,探讨了功能助剂和水性黏合剂对颜料墨水物化性能的影响。结果表明:巴斯夫Efka PX4701对P.Y.74分散效果最佳,当分散剂质量分数为1.6%,消泡剂质量分数为0.04%,研磨转速为1800 r/min时,P.Y.74水相分散体的平均粒径(D50)为27.8 nm,具有优异的高温稳定性。将P.Y.74墨水用于多种纺织品的免前处理和后水洗的短流程数码喷印,其喷印织物字迹清晰,色深和色牢度良好,具有很好的通用性能。In order to improve the quality of pigment digital printing ink,the grinding process and ink physicochemical properties of Pigment Yellow(P.Y.74)aqueous dispersion are systematically investigated by simple variable method.The ink is applied to digital printing of polyester,cotton,nylon fabrics and polyester/cotton blended fabrics.The effects of dispersant type and dosage,defoamer dosage and grinding speed on the dispersibility of P.Y.74 paste are investigated and the effects of functional additives and water-based adhesives on the physicochemical properties of pigment ink are discussed.The results show that BASF Efka PX4701 has the best dispersion effect on P.Y.74.When the dispersant dosage is 1.6%,defoamer dosage is 0.04%and the grinding speed is 1800 r/min,the P.Y.74 aqueous dispersion has excellent high temperature stability with an average particle size(D50)of 27.8 nm.The pigment ink is used for short-process digital printing of a variety of textiles without pre-treatment and post-washing.The prints exhibit good color depth and color fastness,and a clear handwriting as well,therefore,P.Y.74 ink has good universality.
