Abstract

The invention discloses an environment-friendly mordant for natural dye and a preparation method of the environment-friendly mordant. The mordant with good effects is prepared by adopting allanite and organic acid to cooperate with graphene, and the color fixing effect of the natural dye can be effectively improved; meanwhile, rare earth elements contained in allanite do not need to be chemically extracted in the preparing process, therefore, the usage amount of various chemical reagents is greatly decreased, environmental pollution is reduced, and the healthy and environment-friendly requirements of the state on textile industry are met.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to an environment-friendly mordant for natural dyes and a preparation method thereof. Background technique [0002] With the increasing awareness of human environmental protection and the increasing concern for their own health, the harm of some synthetic dyes to human health and the ecological environment has become more and more noticeable. Existing research results have shown that there are 23 kinds of carcinogenic aromatic amines, more than 100 synthetic dyes may produce carcinogens, and more than 20 synthetic dyes are allergic to the skin. As a result, synthetic dyes and the textiles they dye have made consumers suspicious. Not only that, with the continuous consumption of petroleum resources on the earth, the problem of raw materials for synthetic dyes has become increasingly tense. [0003] Natural dyes are extracted from plant roots, leaves, bark, trunk...
