Development of self-coloring fibers not using conventional colorant

近年来，由于芳香胺类染料或颜料具有致癌性或过敏性，在纺织加工领域已受到限制。本文利用食品化学中著名的美拉德染色反应，对聚酰胺纤维或纤维素纤维的新染色方法进行了研究。因此，羊毛纤维与还原糖之一木糖的反应使其呈现深颜色，如深褐色。

The usage of dyestuffs or pigments made of aromatic amines has been recently restrained in the fields of textile processings, because their carcinogenicity or hypersensitivity. In this work, the new coloring methods of polyamide fibers or cellulose fibers were investigated using the Maillard reaction, which is the famous coloration reaction in the fields of food chemistry. As a result, the reaction of wool fibers with xylose, one of reducing sugars, gave their deep coloration, such as dark brown.
