摘　　要：为提高颜料墨水喷墨印花的清晰度,确定适宜的自制颜料墨水的打印参数,以包覆颜料墨水为研究对象,探讨了喷射电压、电压输出波形、频率、喷射距离、喷墨量和基材温度等对其在纯棉织物上喷墨印花清晰度的影响。研究结果表明：喷射电压大,墨滴飞行速度快,会导致喷墨图案清晰度差;选择合适的喷射频率、电压输出波形和喷射距离,均可有效提升喷墨图案的清晰度;提升基材温度可很好地抑制墨水的渗化;喷墨量大,图案边缘渗化严重,印花图案清晰度差;包覆颜料墨水较佳的喷墨打印参数为喷射电压18 V,喷射频率10～30 k Hz,喷射距离0.6～0.8 mm,基材温度40℃。In order to improve the imagine definition of the pigment ink inkjet printing and determine suitable pigment ink printing parameters,taking nano coated pigment ink as the research object,the influence of the jetting voltage,waveform,inkjet amount,jetting frequency,jetting distance and substrate temperature on the accuracy of inkjet printing were studied.Experimental results showed that higher jetting voltage endowed the drops with faster speed which was related to irregular designs.Proper jetting waveform,jetting frequency and jetting distance could improve the accuracy of designs effectively.High temperature could suppress the degree of ink bleeding.The greater the inkjet amount was,the worse the degree of the bleeding.The proper printing parameters was jetting voltage of 18 V,jetting frequency of 10-30 k Hz,jetting distance of 0.6-0.8 mm and temperature of 40 ℃.
