Research as a natural dye of stock of Adzuki bean.

在一家生产红小豆果酱的工厂里，留下了大量的红小豆库存。我一直在研究如何有效地利用这种原料作为染料。本研究对提取物的染色性能、染色方法、染色牢度等进行了考察，在天然纤维中，对羊毛和丝绸的染色性能高于其他织物。最佳染色条件因纤维而异。红小豆染色织物的色牢度达到了较高的等级。考察了加压染色对羊毛的染色效果。此外，在染色方法和处理方法中，在添加剂中对原料进行预处理是有效的。

In a factory to make adzuki bean jam, a large quantity of the stock of the bean is left. I have been studied on the effective utilization of this stock as for the dye. In this study, the extract was examined for the dyeing performance, the dyeing method, the color fastness, and so on. In the natural fiber, the dyeing performance for wool and the silk were higher than other fabrics. The most suitable dyeing condition varied according to fiber. The color fastness of the adzuki bean dyed fabrics showed high grade. The result of having inspected how to dye, pressurization dyeing was effective to wool. Furthermore, the pretreatment of the stock in an additive agent was effective in the dyeing method and disposal method.
