Embodiment 1

[0041] Embodiment 1, Eupatorium odoratum Linn. (Eupatorium odoratum Linn.) Dye preparation and dyeing

[0042] 1) Dye preparation process

[0043] Eupatorium odoratum Linn., also known as airplane grass, belongs to the perennial herb of the genus Eupatorium odoratum in the Asteraceae family. The stems and leaves of vanilla orchid (dry or fresh) are used as raw materials, after being washed and crushed, they can be extracted by two methods of water cold soaking (or hot extraction) (the ratio of water to raw materials is 10:1 and 30:1, respectively).

[0044] Specific extraction process:

[0045] i) cold soaking, extracting the pulverized raw materials with water at room temperature for 12 and 24 hours respectively, filtering, and extracting the filter residue again at room temperature for 6 and 12 hours respectively, filtering off the residue, and combining the two filtrates, After the filtrate is concentrated, it is used as a dye for subsequent use;

[0046] ii) heat extrac...

Embodiment 2

[0053] Embodiment 2, preparation and dyeing of zebra (Mikania cordata (Burm.) B.L.) dyestuff

[0054] 1) Dye preparation process

[0055] Mikania cordata (Burm.) B.L., also known as Mikania cordata, Daphne, Manchrysanthemum, Mikania cordata, Mikania, belongs to the herbaceous liana of the genus Mikania cordata in the family Asteraceae, and the extraction method is the same as in Example 1.

[0056] 2) dyeing process

[0057] With embodiment 1.

[0058] 3) Post-processing

[0059] With embodiment 1.

Embodiment 3

[0060] Embodiment 3, hyacinth blue (Eichhornia crassipes (Mart.) Solms.) Dye preparation and dyeing

[0061] 1) Dye preparation process

[0062] Water hyacinth (Eichhornia crassipes (Mart.) Solms.), also known as water hyacinth and water hyacinth, belongs to the perennial herb of Eichhornia crassipes (Mart.) Solms. The extraction process is the same as in Example 1.

[0063] 2) dyeing process

[0064] With embodiment 1.

[0065] 3) Post-processing

[0066] With embodiment 1.

Abstract

The invention relates to the field of natural dyes, and specifically relates to a natural plant dye, a preparation method and application thereof. According to the invention, the natural plant dye is obtained by extracting vicious weeds serving as raw materials, wherein the vicious weeds are one or more in a group including chromolaena odorata, mikania cordata, water hyacinth, alternanthera philoxeroides, alternanthera pungens, spartina anglica s, ragweed, lantana camara, solanum aculeatissimum and lolium temulentum. The extraction method comprises the steps of grinding and extracting through water. The invention provides a novel scheme for utilizing exotic vicious weeds; the preparation of the natural plant dye by taking exotic invasive weeds as raw materials can protect environment and bring conomic benefits; residue produced during dye extraction can be burnt and combustion can provide a heat source for a dyeing process; and obtained ash can be used as mordanting assistants for dyeing with no storage or treatment so as to really achieve environmental protection.

Description

technical field [0001] The invention relates to the field of natural dyes, in particular, the invention relates to a natural plant dye and its preparation method and application. Background technique [0002] With the strengthening of people's awareness of environmental protection and the increasing emphasis on human health, the side effects of some synthetic dyes on human health and the ecological environment have attracted more and more attention. Studies in recent years have shown that more than 100 commonly used dyes may produce carcinogens. In 1994, developed countries such as Germany promulgated regulations to ban these dyes. Not only that, with the consumption of the earth's oil resources, the problem of raw materials for synthetic dyes has been exposed, so researchers have begun to devote themselves to the development of "natural and environmentally friendly dyes" and "environmentally friendly and clean dyeing and finishing processes". [0003] Dyeing with natural ...
