摘要：利用小分子还原糖-羊毛角蛋白的美拉德反应对羊毛织物进行无染料着色，分别通过十二烷基硫酸钠-聚丙
烯酰胺凝胶电泳（SDS-PAGE）、分光光度法、二硝基水杨酸（DNS）显色法以及染色织物得色量（以 K/S 值表
征）考察了还原糖与角蛋白的反应、还原糖的种类和反应条件对羊毛织物染色性能的影响。结果表明，还原糖
与角蛋白发生了反应形成了更大相对分子质量的糖蛋白，反应液在 540 nm 处的吸光值发生明显变化，意味着还
原糖与角蛋白发生美拉德反应形成了有色物质；相对于半乳糖和葡萄糖，木糖对羊毛织物的着色具有更高的得
色量；羊毛织物着色的适宜条件为反应温度 90 ℃、反应 pH=9；以过氧化氢对羊毛织物进行预处理，经葡萄糖
染色 5 h 后，预处理羊毛织物的得色量较去离子水浸泡处理的得色量提高了约 23%；经美拉德反应着色的羊毛
织物具有良好的耐洗色牢度、耐刷洗色牢度及耐干/湿摩擦色牢度，分别达到 4~5、5、5/5 级，但其耐光色牢度
只能达到 2 级。

Abstract: Dye-free coloration of wool fabric was performed via Maillard reaction of small-molecule
reducing sugars and wool keratin.The influences of reaction between reducing sugars and wool keratin, the
type of reducing sugars and reaction conditions on the dyeing performance for wool fabric were
investigated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE),
spectrophotometry, dinitrosalicylic acid (DNS) coloring method and color yield (K/S value). The results
showed that new glycoprotein with relatively larger molecular mass was formed after the reaction, and the
absorbance of the reaction liquid changed obviously at 540 nm, suggesting a colored substance formed via
Maillard reaction of the reducing sugar with keratin. Compared with galactose and glucose, xylose led to
higher color yield on wool fabric. The optimum conditions for wool fabric coloration with reducing sugars
were obtained as follows: coloration temperature of 90 ℃ and pH of 9. Meanwhile, compared to wool
fabric treated with deionized water, the color yield of wool fabric pretreated with hydrogen peroxide was
significantly increased by 23% after dying with glucose for 5 h. Maillard reaction imparted the colored
wool fabric good color fastness of washing, brushing and dry/wet rubbing of level 4~5, 5, 5/5 respectively,
but the light fastness was only level 2.
