摘要: 为了探究甜菜色素衍生物的合成方法及其应用性能,以粗制天然甜菜红色素、VPOC 1065阴离子交换树脂、吲哚啉为原料,通过固相反应和置换反应合成了中间体a及甜菜色素衍生物(色素A)。优化了合成色素A的反应条件和染色羊毛工艺,测定了经硫酸铝钾前媒处理染色织物的各项牢度。结果表明:合成色素A的最佳工艺条件为吲哚啉质量与中间体a的质量比3∶8,反应时间25 min,产率为50.13%;染色工艺为:染色pH值为3.0、染色温度50 ℃、染色时间110 min、染料质量分数5%(o.w.f)。合成色素A有较好K/S 值,耐皂洗色牢度、耐摩擦色牢度及耐日晒色牢度均达到3级以上。

Abstract: In order to explore the synthesis method and application performance of beet pigment derivatives, the intermediate "a" and the beet pigment derivative(pigment A) were synthesized by solid phase and replacement reaction using crude natural beet pigment, VPOC1065 anion exchange resin and indoline as raw materials. The reaction conditions of synthetic pigment A and dyeing process of wool were optimized, and the fastnesses of dyed fabrics treated with pre-medium of potassium aluminum sulfate were measured. The results show that the optimal process conditions for the synthesis of pigment A are that the mass ratio of indoline to intermediate a is 3:8, the reaction time is 25 min, and the yield is 50.13% and that the dyeing pH value is 3.0, dyeing temperature is 50 °C, dyeing time is 110 min, and dye mass fraction is 5%(o.w.f). Synthetic pigment A has good K/S value, and the fastness to soaping,color fastness to rubbing as well as colour fasteness to sunlightall surpass level 3.

Key words: solid phase reaction, beet pigment derivative, wool, pre-mordant dyeing, color fastness
