摘　　要：棉纤维和锦纶表面性质的巨大差异使喷墨印花墨水在棉/锦交织织物2种纤维上的铺展与渗化行为不同,为棉/锦交织织物喷墨印花获得清晰图案带来了巨大困难。针对这一问题,选取了多种水溶性聚合物分别对棉/锦交织织物进行表面改性,对比研究了改性后的棉纤维和锦纶表面性质的变化。结果表明:当使用羟乙基甲基纤维素对棉/锦交织织物改性后,棉纤维表面亲水性减弱,锦纶表面亲水性增强;在羟乙基甲基纤维素改性后的棉/锦交织织物上喷墨打印青色、品红、黄色和黑色色块的染色深度值较使用海藻酸钠改性分别提升34.6%、45.0%、40.0%和31.5%;羟乙基甲基纤维素改性有利于棉/锦交织织物喷墨印花色深和图案清晰度提升。The large difference in surface properties of cotton and polyamide fibers makes the spreading and permeation behaviors of dye inks different on the two fibers,which brings great difficulties for the inkjet printing of cotton/polyamide interwoven fabrics to obtain clear patterns.Herein,the surface properties of the cotton and polyamide fibers were modified by using multiple polymers for the cotton/polyamide interwoven fabrics.The results showed that the effect for the two fibers were different when the cotton/polyamide interwoven fabric was modified by only hydroxyethyl methyl cellulose.The hydrophilicity of the cotton fiber surface was decreased while the hydrophilicity of the polyamide fiber surface was enhanced.The dye depth values of cyan,magenta,yellow,and black on the interwoven fabric modified with hydroxyethyl methyl cellulose were increased by 34.6%,45.0%,40.0%,and 31.5%,respectively,compared with fabric modified with sodium alginate.Meanwhile the ink-jet printing pattern definition of the modified cotton-polyamide interwoven fabric was improved as a result.
