摘要
对蚕丝和棉织物活性染料喷墨印花的上浆预处理和喷印后汽蒸进行比较研究,结果表明:用海藻酸钠和羧甲基纤维素上浆的蚕丝印花织物颜色深度相近,而棉织物则是用羧甲基纤维素上浆时颜色深度更高;用碳酸氢钠作碱剂时,蚕丝和棉织物在颜色深度和颜色稳定性方面的表现更佳;为了获得较深的颜色,棉织物较蚕丝织物需要更多的碱剂和尿素,而所需元明粉的用量是相同的;在汽蒸时,活性染料在棉上的固色率低于在蚕丝上的固色率,但其固色速率高于在蚕丝上的固色速率;蚕丝和棉织物的最佳喷墨印花工艺参数有所不同。
The reactive inkjet printing of silk and cotton fabrics is investigated in terms of sizing pretreatment and steaming after printing. The silk prints sizing with sodium alginate and carboxymethyl cellulose respectively exhibit the similar color depth, whereas the cotton prints sizing with carboxymethyl cellulose show higher color depth. The use of sodium bicarbonate as an al kaline agent displays a satisfactory result in the aspects of color depth and color stability. In order to achieve better color depth, cotton prints call for more alkali and urea dosages than the silk prints, as well as the sodium sulfate dosage. In the steaming process after inkjet printing, cotton prints show a lower dye fixation ratio and higher fixing rate than those of the silk prints. The optimum printing parameters for silk and cotton are different from each other.
