Problems solved by technology

In addition, wintergreen also contains a variety of essential trace elements for the human body, which has important health care value. It can not only supply the daily necessary nutrients for the human body, but also regulate the functions of the human body. At present, there is no research on wintergreen. In-depth, especially the extraction of the natural pigments of cervium and its application in textile dyeing have not been studied, so it is of great significance to study the extraction of cerimin and its application in textile dyeing

Embodiment Construction

[0023] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0024] Extraction of Wintergreen Pigment

[0025] First use a pulverizer to crush the wintergreen into powder. The extraction conditions are: the molar concentration of sodium hydroxide is 0.05-0.45mol / L, the temperature is 50-100°C, the time is 5-90min, and the ratio of solid to liquid (Certium and sodium hydroxide The mass ratio of the solution) is 1:10 to 1:80, after the extraction is completed, it is cooled, filtered, and set aside.

[0026] Direct dyeing of wool with wintergreen

[0027] Weigh 25g of S. cerevisiae powder, extract according to the optimized extraction process, then set the volume to 1000mL, and calculate the concentration of the dye solution as 25g / L. Prepare a dye ...

Abstract

The invention discloses an extracting method and application of pyrola calliantha dye. The method comprises the steps that pyrola calliantha is smashed into powder with a pulverizer, and the extraction conditions are that the sodium hydroxide molar concentration ranges from 0.05 mol / L to 0.45 mol / L, the extraction temperature ranges from 50 DEG C to 100 DEG C, the extraction time ranges from 5 min to 90 min, the solid-to-liquid ratio, namely, the mass ratio of the pyrola calliantha to a sodium hydroxide solution ranges from 1:10 to 1:80, and after extraction is completed, cooling and filtration are conducted; the dye is used for conducting direct dyeing and mordant dyeing on wool. The extracting method and application of the pyrola calliantha dye have the advantages of being green, environmentally friendly and free of pollution, having important health-care value and being high in dyefastness and resistant to abrasion, soaping and light.

Description

technical field [0001] The invention discloses an extraction method and application of a fuel, in particular a cervium dye and an extraction method and application thereof. Background technique [0002] At present, the dyeing of wool fabrics usually uses neutral or weak acid dyes in chemically synthesized dyes, because the sources are mainly petroleum and coal and the pollution is serious. In the long run, resources are becoming increasingly scarce and cannot be recycled, which is not in line with sustainable development and environmental protection. requirements. Natural dyes refer to those dyes obtained from natural resources such as animals, plants or minerals with little or no chemical processing, mainly vegetable dyes. Dyeing with natural dyes, the color of the dyed product is natural, can greatly reduce the toxicity of dyeing wastewater, help reduce the burden of sewage treatment, and protect the environment. [0003] Wintergreen belongs to the Wintergreen family Win...
