摘　　要：为提升喷墨印花棉与聚酰胺织物的图案效果,将海藻酸钠(SA)和十二烷基三甲基氯化铵(DTAC)用于棉与聚酰胺织物的预处理工艺,对喷墨印花织物的颜色参数进行测试,分析SA和DTAC改性对棉与聚酰胺织物的表观颜色深度、图案印花清晰度、色牢度和力学性能的影响。结果表明:与SA改性织物相比,DTAC的引入可使棉与聚酰胺织物的表观颜色深度增加,图案清晰度提升,防渗化效果变好,色牢度和断裂强力没有明显改变;经过DTAC改性,改性剂在棉与聚酰胺织物表面形成了薄膜,填充了纤维之间的毛细孔隙,使得更多的活性染料与纤维共价结合,进而提高了喷墨印花图案的颜色深度和印花清晰度。In order to improve the pattern effect of ink-jet printed cotton/polyamide fabric,the sodium alginate(SA)and dodecyl trimethyl ammonium chloride(DTAC)were used in the pretreatment process of cotton/polyamide fabric,and the color parameters of ink-jet printed fabric were tested.The effects of SA and DTAC modification on apparent color depth,graphic printing clarity,color fastness and mechanical properties of cotton/polyamide fabrics were analyzed.The results show that compared with SA pretreated fabric,the introduction of DTAC increases the apparent color depth and pattern clarity of cotton/polyamide fabric,improves the anti-seepage effect,but has no significant changes in color fastness and breaking strength.After DTAC modification,the modifier forms a film on the surface of cotton/polyamide fabric,which fills the pores between fibers.More reactive dyes can be covalently combined with fibers to improve the color depth and clarity of inkjet printing patterns.
