棉织物新型涂料数码喷墨印花应用性能研究

Research on the Application Performance of Digital Inkjet Printing of New Coatings for Cotton Fabrics

针对传统涂料数码喷墨印花工艺中喷涂织物处理液和高温固色的环节,通过使用新型涂料数码喷墨印花工艺可省去上述环节,以达到缩短工艺流程、节能环保、减少废气排放、降本增效的目的。通过对新型涂料数码喷墨印花技术和传统涂料数码喷墨印花技术进行对比研究,将使用两种喷墨印花工艺的棉织物分别进行颜色特征值、色牢度、pH值、硬挺度、折皱回复角的测试。结果表明,新型涂料数码喷墨印花工艺在绿色节能、降低成本的同时,其耐摩擦色牢度、硬挺度和折皱回复角方面的表现优于传统涂料数码印花工艺;在颜色特征值、pH值和耐皂洗色牢度方面与传统涂料数码印花工艺性能相当。总体来说,新型涂料数码喷墨印花工艺符合绿色印染的发展方向,降低了企业生产成本,对企业实际的生产有一定的参考意义,具有广阔的应用前景和发展潜力。

In view of the links of spraying fabric treatment liquid and high-temperature color fixing in the traditional pigment digital inkjet printing process,the above links can be omitted by using the new pigment digital inkjet printing process,so as to achieve the purpose of shortening the process,saving energy and environmental protection,reducing exhaust emissions,reducing costs and increasing efficiency.Through the comparative study of the new pigment digital inkjet printing technology and the traditional pigment digital inkjet printing technology,the pure cotton fabrics using the two inkjet printing processes were tested for color characteristics,color fastness,pH value,stffness and wrinkle recovery angle.The results show that the new digital inkjet printing process is better than the traditional digital printing process in terms of color fastness to rubbing,stiffness and wrinkle recovery angle while saving energy and reducing costs.In terms of color characteristics,pH value and color fastness to soaping,it is comparable to the digital printing process performance of traditional coatings.In general,the new coating digital inkjet printing process is in line with the development direction of green printing and dyeing,reduces the production cost of enterprises,has certain reference significance for the actual production of enterprises,and has broad application prospects and development potential.
