摘要
为探索研究适用于真丝绸数码印花用的活性染料墨水,选择了国内市场上8个典型品牌的活性染料墨水,从墨水p H值、电导率、吸收光谱特性、色域范围,以及印制织物的得色、干湿摩擦色牢度等方面进行对比评估。结果表明,各品牌墨水p H值范围处于中性或弱酸性,可避免活性染料过度水解以改善其稳定性;较低的电导率有利于避免盐类结晶而造成的喷嘴堵塞和腐蚀问题;各品牌活性墨水中CMY三原色色相稳定,而BRO三只专色则存在一定差别,且在不同亮度水平下整体色域范围存在差异。同时,真丝绸数码印花印制性能研究表明,提高活性数码印花墨水的稳定性有利于改善印花织物的得色量和色牢度性能。
In order to explore suitable reactive inks for silk digital printing,reactive dye inks of eight brands were selected from the domestic market to evaluate their pH,conductivity,absorption spectrum,color gamut range and their application performance including color yield,dry and wet rubbing fastness.The results showed that pH values of ink of different brands ranged from neutral and weakly acidic property,which would be helpful to reduce hydrolysis of the reactive dye and improve their stability.Reactive inks with lower conductivity could avoid salt crystallization which would cause nozzle blocking and corrosion problem.The hue of three primary colors(CMY)was stable,while that of spot color(BRO)had some differences,and the overall gamut range of these ink sets were different at different brightness levels.The application performance of the printed silk demonstrated that the increase in the stability of reactive ink would improve the color yield and color fastness of the printed fabric.
