摘要:

采用β-环糊精和柠檬酸为原料合成柠檬酸-β-环糊精,将其用于涤纶织物颜料墨水喷墨印花预处理,改善喷墨印花的清晰度和颜色深度。FTIR谱图中1736cm-1附近酯键特征吸收峰表明合成产物柠檬酸-β-环糊精的形成。柠檬酸-β-环糊精处理后的涤纶织物喷墨印花清晰度由12.5%增加至70.0%,说明印花宽度更接近于设置宽度,渗化现象减弱。织物上印花色块的K/S值由3.6增至5.9,颜色深度增加。柠檬酸-β-环糊精处理后涤纶织物的润湿性和柔软度相比未处理织物略有下降。扫描电镜图进一步表明,涤纶纤维表面及纤维之间的空隙处覆盖着一层柠檬酸-β-环糊精薄膜,增加了纤维表面的粗糙度,降低了毛细管效应,提高了织物的防渗化性能。

Abstract:

The citric acid-β-cyclodextrin was synthesized from β-cyclodextrin and citric acid and applied on the pigment inkjet printed polyester fabric as pretreatment to improve the definition and color depth. The ester linkage absorption peak at 1736 cm-1 confirmed the formation of citric acid-β-cyclodextrin. The definition was increased from 12.5 % to 70.0%. It is indicated that the printed width was more close to the set width, the penetration was reduced. The enhanced K/S value of the printed color lump from 3.6 to 5.9 illustrated the improved color depth. The wettability and softness of the citric acid-β-cyclodextrin pretreated fabric was a little decreased when compared to the untreated one. SEM images clarified that the polyester fiber surface and the spaces between the adjacent fibers were covered with the film of citric acid-β-cyclodextrin, improving the roughness and reducing the capillary effect.
