Problems solved by technology

Since the extraction process conditions are carried out in aqueous solution, the extraction efficiency is low. In addition, this invention is only suitable for the production of medicines, and cannot meet the requirements for the production of dye products.
In addition, there are no reports at home and abroad about the application method of mimosa plant dyes.

Embodiment 1

[0026] Collect Mimosa plants, wash, dry, and crush them through a 10-mesh sieve, weigh 1kg of plant materials and add 25% ethanol solution, wherein the weight ratio of Mimosa plant materials to solvents is 1:10, and place the solid-liquid mixture in Mix evenly at room temperature of 10°C, extract natural dye solution at room temperature for 12 hours, then filter to obtain dye solution, concentrate the extracted dye solution stock solution under reduced pressure at 40°C to make a paste-like concentrated solution, and dilute the dye concentrated solution After solidification and concentration, it is made into natural powdery dye powder, that is, mimosa plant dye.

Embodiment 2

[0028] Collect the mimosa plants, wash them, dry them, and pass them through a 50-mesh sieve after they are crushed. Take 1 kg of plant materials and add 50% ethanol solution, wherein the weight ratio of the mimosa plant materials to the solvent is 1:15, and place the solid-liquid mixture in Mix evenly at room temperature of 20°C, extract the natural dye solution at room temperature for 18 hours, then filter to obtain the dye solution, concentrate the extracted dye solution under reduced pressure at 45°C to make a paste concentrate, and dilute the dye concentrate After solidification and concentration, it is made into natural powdery dye powder, that is, mimosa plant dye.

Embodiment 3

[0030] Collect the mimosa plants, wash them, dry them, and pass them through a 100-mesh sieve. Weigh 1kg of plant materials and add 95% ethanol solution, wherein the weight ratio of the mimosa plant materials to the solvent is 1:20. Mix well at room temperature of 35°C, extract the natural dye solution at room temperature for 24 hours, then filter to obtain the dye solution, concentrate the extracted dye solution stock solution under reduced pressure at 50°C, and make a paste-like concentrated solution. After solidification and concentration, it is made into natural powdery dye powder, that is, mimosa plant dye.

Abstract

The invention discloses a method for preparing and applying sensitive plant dye in the dye technical field. The method comprises the following preparation steps that: sensitive plants are collected, cleaned, aired, ground, added to an ethanol solution, digested and extracted at room temperature and filtered so as to obtain a dye solution; an extracted stock solution of the dye solution is decompressed, concentrated and made into a paste-shaped concentrated solution; and the dye concentrated solution is cured, concentrated and made into natural powder-shaped dye powder. Under the alum mordant dyeing condition, an obtained fabric is yellow; under the copper salt mordant dyeing condition, obtained real silk fabrics are deep yellow, while cotton or woolen fabrics are green; and under the metallic ferrous salt mordant dyeing condition, the obtained fabrics are olive. The method utilizes the natural nontoxic sensitive plants to dye real silk, cotton or woolen fabrics, provides a technical basis for reducing the use of synthetic dye and developing natural dye, can be applied to the clean production of the textile industry, and can be used for mass production.

Description

technical field [0001] The invention relates to a preparation and application method in the technical field of dyes, in particular to a preparation and application method of a mimosa plant dye. Background technique [0002] Mimosa is the whole herb of Mimosa pudica in the family Leguminosae. Mimosa is native to the tropical regions of South America. It likes warmth and humidity. It is not strict on the soil. It likes light, but it can tolerate half shade, so it can be used as an indoor potted flower. The leaflets of Mimosa are small and arranged in a pinnate shape. When you touch the leaflets with your hands, they will close up after being stimulated. If the vibration force is strong, the stimulation can be transmitted to the whole leaf, and the total petiole will also droop, and it can even be transmitted to adjacent leaves. The leaves make their petioles droop, as if a girl is shy and hangs down her noodles, hence the name Mimosa. [0003] Mimosa is also a kind of medici...
