摘　　要：为提升墨滴在蚕丝/粘胶交织物表面的颜色性能及清晰度,采用羧甲基纤维素钠(CMC)、海藻酸钠(SA)对蚕丝/粘胶交织物进行改性处理。探究了CMC及SA对织物改性效果的影响,测试了不同工艺下改性织物表面的墨滴铺展面积和颜色性能,并通过扫描电子显微镜、红外光谱和接触角仪对改性前后织物的表观形貌、化学结构和润湿性能进行了分析。结果表明,经过CMC+SA改性后,青色和品红色墨滴铺展面积分别减小到148.1 mm^(2)和199.6 mm^(2),青色和品红色块的K/S值分别提升了8.4和11.4,表明CMC与SA填充了纤维间的孔隙,织物的润湿性增加,有效抑制墨滴在织物表面的扩散,增加了活性染料与纤维共价结合的可能性,进而改善了喷墨打印图案的效果。In order to improve the color performance and clarity of ink droplets on the surface of silk/viscose mixture,sodium carboxymethyl cellulose(CMC)and sodium alginate(SA)are used to modify the silk/viscose mixture.The effects of CMC and SA on the modification effect of the fabric are investigated,and the spread area and color performance of ink droplet on the surface of the modified fabric are tested under different processes.The apparent morphology,chemical structure and wettability of the fabric before and after modification are analyzed by scanning electron microscopy,infrared spectroscopy and contact angle instrument.The results show that after CMC+SA modification,the spreading area of blue and magenta ink droplets decreases to 148.1 mm^(2) and 199.6 mm^(2),respectively,and the K/S values of cyan and magenta blocks increase by 8.4 and 11.4,respectively,indicating that CMC and SA fill the pores between fibers,increasing the wettability of fabrics,effectively inhibiting the diffusion of ink droplets on the surface of the fabric,increasing the possibility of covalent binding between reactive dyes and fibers,and thereby improving the effect of inkjet printing patterns.
