Abstract

The invention discloses a preparation method of a vegetable dye and belongs to the technical field of printing and dyeing. According to the method, the following raw materials in parts by weight are used: 4-5 parts of digitaria ciliaris and 6-7 parts of sargent gloryvine. The method comprises the following steps: A, putting the digitaria ciliaris in a container and adding 95-105 parts of water to boil, bringing to boil and keeping for 10-15min, and filtering to obtain filtrate for after use; B, triturating the sargent gloryvine to obtain triturated sargent gloryvine; C, adding the filtrate prepared in the step A into the triturated sargent gloryvine prepared in the step B and uniformly stirring to obtain a mixture; D, bringing the mixture prepared in the step C to boil and keeping for 5-6h to obtain the vegetable dye. The preparation method can be used for solving the problem that the synthetic dyes contain cancerogenic substances so as to cause harm to the human body and are not environment-friendly.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a method for preparing vegetable dyes. Background technique [0002] Dye is a substance that can color fibers and other materials. It directly contacts people's skin during use. The raw materials and intermediates of commonly used synthetic dyes often contain carcinogenic substances, which not only seriously pollute the environment, but also cause direct wear. or producers are harmed.
