Embodiment 1

[0024] Embodiment 1, a kind of preparation method of plant dyeing agent

[0025] Preparation of compound mordant: compound vitriol and tannic acid in weight ratio to obtain mixture I, then mix it with water in a weight ratio of 3:250, stir well and mix evenly to obtain the product.

[0026] Preparation of plant dyeing agent: Weigh the compound thickener, soybean powder, and compound mordant respectively, mix them well, stir them well, make them fully mixed, and let them stand still to get ready.

Embodiment 2

[0027] Embodiment 2. A plant dyeing agent, made of the following raw materials in parts by weight: 1 part of compound thickener, 12 parts of compound mordant, and 0.5 part of soybean powder.

[0028] Preferably, a plant dyeing agent is made of the following raw materials in parts by weight: 2 parts of compound thickener, 14.5 parts of compound mordant, and 1 part of soybean powder.

[0029] Among them, the compound thickener is composed of kale gum and guar gum, and the compound mordant is made of vitriol, tannic acid and water. The weight ratio of squash gum to guar gum is 9:1, and the weight ratio of vitriol to tannic acid is 9:1.

[0030] The preparation method is similar to Example 1.

Embodiment 3

[0031] Embodiment 3, a plant dyeing agent, made of the following raw materials in parts by weight: 3 parts of compound thickener, 18 parts of compound mordant, and 2 parts of soybean powder.

[0032] Preferably, a plant dyeing agent is made of the following raw materials in parts by weight: 2 parts of compound thickener, 14.5 parts of compound mordant, and 1 part of soybean powder.

[0033] Among them, the compound thickener is composed of squash gum and carrageenan, and the compound mordant is made of green vitriol, tannic acid and water. The weight ratio of squash gum and carrageenan is 7:3, and the weight ratio of vitriol and tannic acid is 9:1.

[0034] The preparation method is similar to Example 1.

Abstract

The invention discloses a plant coloring agent and a preparation method thereof. The plant coloring agent is composed of 1-3 parts of a compound thickening agent, 12-18 parts of a compound mordant and 0.5-2 parts of soybean meal. The compound thickening agent comprises sesbania gum, guar gum or carrageenan. The compound mordant is prepared from copperas, tannic acid and water. The weight ratio of the sesbania gum to the guar gum is 9: 1, and the weight ratio of the sesbania gum to the carrageenan is 7: 3. The weight ratio of the copperas to the tannic acid is 9: 1. The invention also provides the preparation method of the plant coloring agent. The plant coloring agent is relatively good in printing performance, clear in pattern outline edge after fabric dyeing, good in permeability and relatively high in color fastness.

Description

technical field [0001] The invention relates to the field of fabric dyeing technology, in particular to a vegetable dye and a preparation method thereof. Background technique [0002] Vegetable dyeing refers to the process of dyeing fabric products with natural dyes and without or little use of chemical auxiliaries in the dyeing process, but with natural dyes obtained from nature. [0003] Plant dyes, also known as plant dyes, refer to dyes that use natural flowers, grasses, trees, stems, leaves, fruits, seeds, skins, and roots to extract pigments as fabrics. Plant dyes are non-toxic and harmless, and will not cause harm to human health. Fabrics dyed with plant dyes have natural color and shape, and will not fade for a long time; they have the functions of insect repelling and antibacterial, which are not available in chemical dyes. Especially suitable for children's clothing, underwear, footwear, car interior, luggage, interior, bedding, etc. The color fastness is high, ...
