Embodiment 1

[0050] A preparation method of Eupatorium adenophorum staining solution includes the following steps:

[0051] (1) Preparation of dechlorinated softened water: first pump the tap water into a 50 cubic meter water storage tank, and let it stand for 1 night (8-12 hours) in the water storage tank for dechlorination; then the dechlorinated tap water is treated with soft water And remove the calcium and magnesium ions in the water to obtain dechlorinated softened water at room temperature for use; the water softener used in this embodiment is a CLSN-18-BL-DA model sold by Beijing Kelijie Water Treatment Engineering Co., Ltd. Automatic water softener.

[0052] (2) Preparation of dechlorinated softened hot water: take a part of the dechlorinated softened water prepared in step (1) and pass it into a solar water heater to be heated to 85~87℃; the hot water that has been heated to 85~87℃ is then supplied The constant temperature hot water tank is kept warm for use, and the outer circumfere...

Embodiment 2

[0088] The rest of this embodiment is the same as embodiment 1, the difference is:

[0089] In step (1), in the process of treating tap water, after the tap water is processed by the water softener, it is further passed into the water purifier for further purification treatment. The water purifier is Shanghai Lisheng Water Purifier. LH3-8AD type water purifier produced by Equipment Co., Ltd.

[0090] Washing with the softened water prepared in step (1) of this embodiment, soaking Eupatorium adenophorum, filtering, concentrating, and adding ferrous sulfate to configure the white cotton cloth dyed with the dye liquor to have a softer color than the fabric dyed in Example 1; For the dyeing of high-end fabrics such as silk, the soaking water is preferably treated with three steps of dechlorination, softening and purification.

Embodiment 3

[0092] The rest of this embodiment is the same as embodiment 1, except that:

[0093] In step (2), when the soaking water is heated, the dechlorinated and softened water is heated to 72-73°C by a solar water heater; the hot water heated to 72-73°C is passed into a constant temperature hot water tank for heat preservation until use.

[0094] In step (4), when the granular Eupatorium adenophorum is soaked, the mass ratio of Eupatorium adenophorum to water is 1:14, and the water temperature is kept at 72-73° C. in the soaking tank, and the Eupatorium adenophorum is soaked in water for 6 hours.

Abstract

The invention provides crofton weed dye liquor as well as a preparation method and an application thereof. The preparation method of the crofton weed dye liquor is simple in process and is suitable for large-scale industrial production; after a concentrated solution is prepared, the concentrated solution is directly prepared into dye liquor to perform dyeing, and the steps of treating waste water in a process of continuously concentrating and drying the concentrated solution to prepare a solid dye in the prior art are eliminated, therefore, the after treatment of the waste water is simpler; furthermore, crofton weeds are pickled in saline water at first, which contributes to cell dehydration and deactivation of the crofton weeds, promotes further separation of pigment and contributes to improving the extraction efficiency of subsequent soaking; and the obtained crofton weed dye liquor is high in pigment concentration, and can reduce the soaking extraction temperature, shorten the extraction time, lower the energy consumption, and reduce the added amount of the crofton weeds, thus the cost is effectively reduced. The crofton weed dye liquor provided by the invention can be used for dyeing plants, and is excellent in dyeing effect, strong in color fastness, and soft in color, and various indexes are superior to a standard of infantile textiles.

Description

Technical field [0001] The invention relates to the technical field of natural dyes, and in particular to a dye solution of Eupatorium adenophorum and its preparation method and application. Background technique [0002] Dyes are substances that can color fibers and other materials. They are usually divided into two categories: natural dyes and synthetic dyes. Natural dyes are divided into vegetable dyes and animal dyes. Synthetic dyes, also known as artificial dyes, are mainly made from coal tar fractionation (or petroleum processing) through chemical processing. For synthetic dyes, the raw materials are petroleum and coal, which are consumed quickly and are difficult to regenerate. The production and use of synthetic dyes have certain environmental pollution, and the recovery rate of dyeing wastewater from synthetic dyes is low and difficult to treat. For plant dyes, the raw materials are extracted from plants. The production and use of natural plant dyes are compatible with ...
