为方便提高活性油墨喷墨印花的显色率，设计了采用海藻酸钠、缩水甘油三酯氯化铵（GTA）、氢氧化钠、尿素组成的前处理配方对棉织物进行一浴前处理，同时实现上浆和阳离子化。根据阳离子棉对品红油墨的显色率的测定结果，优化了GTA和碱的浓度、焙烧温度、焙烧时间等预处理条件。探讨了GTA改性织物增色机理，并研究了GTA在印花浆料中的稳定性。对改性棉和未改性棉的扫描电镜、撕裂强度和热重分析进行了研究和比较。在最佳预处理条件下，阳离子棉对品红、青色、黄色和黑色活性油墨的显色率分别比未阳离子棉的显色率提高128.7%、142.5%、71.0%和38.1%。使用这种一浴预处理方法产生的废水要少得多。通过彩色图案喷墨印花，比较了活性染料在改性棉和未改性棉上的色牢度，评价了不同颜色之间的界限清晰度。
In order to facilely increase the color yield of ink-jet prints using reactive inks, one-bath pretreatment of cotton fabrics with pretreatment formulation containing sodium alginate, glycidyltrimethylammonium chloride (GTA), sodium hydroxide, and urea is designed for realizing sizing and cationization at the same time. The pretreatment conditions, including the concentrations of GTA and alkali, baking temperature, and time are optimized based on the result of thecolor yield on cationic cotton for magenta ink. The mechanism for color yield enhancement on GTA-modified fabrics is discussed and the stability of GTA in the print paste is investigated. Scanning electron microscopey, tear strength, and thermogravimetric analysis of the modified and unmodified cotton are studied and compared. Using the optimal pretreatment conditions, color yield on the cationic cotton for magenta, cyan, yellow, and black reactive inks are increased by 128.7%, 142.5%, 71.0%, and 38.1%, respectively, compared with the corresponding color yield on the uncationized cotton. Much less wastewater is produced using this one-bath pretreatment method. Colorfastness of the reactive dyes on the modified and unmodified cotton is compared and boundary clarity between different colors is evaluated by ink-jet printing of colorful patterns.
