The invention relates to a rare earth mordant dyeing method for kapok fibers and textiles thereof. The method comprises the following steps: pre-treating kapok textile so as to remove some waxy xubstances, impurities and the like on the surface of the kapok fiber and achieve certain whiteness; and then adding a complexing rare earth mordant into a dye bath of the pretreated kapok textile, and mordant dyeing the kapok textile. Compared with the prior art, according to the dyeing method of the invention, the dyeing of the kapok fibers and textiles thereof is not limited to direct dyes and can also be used for other anionic dyes such as reactive dyes and the like, and the problems of low rate of dye-uptake, poor level-dyeing property, poor deep-color dyeing effect, poor dyeing fastness and the like are overcome. |
