Description

flower dyeing process

technical field

The invention relates to a flower dyeing and shaping process.

Background technique

Along with the raising of people's living standard, the fresh-keeping of fresh flower is the focus that people pay close attention to. Although the fresh-keeping treatment of fresh flowers has certain effects at present, it is only limited to dried flowers. Dried flowers are flowers and plants that grow in nature, which are quickly dehydrated and dried by scientific methods to become flowers that maintain their original color and shape, or artificially dyed to form more colorful dried flowers. But dried flowers are easy to break and break.

Contents of the invention

Purpose of the invention: In order to solve the deficiencies of the prior art, the present invention provides a flower dyeing and setting process that can keep fresh flowers for a long time and make them come alive.

The technical solution adopted in the present invention: a fresh flower dyeing and shaping process, which comprises the following steps:

1. Bleaching process: put fresh flowers in an anhydrous ethanol solution containing hydrogen peroxide for 1-3 hours;

2. Dyeing and setting process: dyeing and setting with 0.1%-0.5% of the quality of fresh flowers, dyeing agent and ethanol mixture for 1-2 hours, the quality of the setting agent and ethanol mixture is 45-55 times of the quality of fresh flowers;

3. Drying process: Dry the dyed and finalized flowers at 50-60°C.

In the above step 1, the volume ratio of the hydrogen peroxide to absolute ethanol is 1:2-5.

In the above step 2, the dye is a cationic dye or a solvent-based dye, and the amount of the dye is determined according to the depth of the color. The cationic dye needs to be dissolved in a small amount of water before reuse; the fixing agent is composed of polyethylene glycol PEG600 and polypropylene glycol It is obtained by compounding PPG1000, and the mass ratio of setting agent and ethanol is 1:2-4.

Beneficial effects: the flowers obtained by the invention have clear veins, are lifelike, and can be stored for a long time.

Detailed ways

The present invention will be further described below in conjunction with specific embodiment:

Example 1

A fresh flower dyeing and shaping process, it comprises the steps:

1. Bleaching process: put fresh fresh flowers in an anhydrous ethanol solution containing hydrogen peroxide and bleach for 3 hours, and the volume ratio of the hydrogen peroxide to anhydrous ethanol is 1:2;

2. Dyeing and setting process: dyeing and setting with 0.1% of the mass of fresh flowers, dye, setting agent and ethanol mixed solution for 1 hour, the dye is a cationic dye or a solvent dye, and the setting agent is composed of polyethylene glycol PEG600 and polypropylene glycol It is obtained by compounding PPG1000, the quality of the mixed solution of the fixing agent and ethanol is 45 times that of fresh flowers, and the mass ratio of the fixing agent and ethanol is 1:2;

3. Drying process: drying the dyed and finalized flowers at 50°C.

The fresh flowers can be preserved for 18 months in a clean environment after the above-mentioned dyeing and setting process.

Example 2

A fresh flower dyeing and shaping process, it comprises the steps:

1. Bleaching process: put fresh fresh flowers in an anhydrous ethanol solution containing hydrogen peroxide and bleach for 2.5 hours, and the volume ratio of the hydrogen peroxide to anhydrous ethanol is 1:3.5;

2. Dyeing and setting process: dyeing and setting with 0.3% of the quality of fresh flowers dye, fixative and ethanol mixture for 1.5h, the dye is a cationic dye or a solvent dye, and the fixative is composed of polyethylene glycol PEG600 and polypropylene glycol It is obtained by compounding PPG1000, the mass ratio of the fixative and ethanol mixture is 50 times that of fresh flowers, and the mass ratio of the fixative and ethanol is 1:3;

3. Drying process: drying the dyed and finalized flowers at 55°C.

The fresh flowers can be preserved for 21 months in a clean environment after the above-mentioned dyeing and setting process.

Example 3

A fresh flower dyeing and shaping process, it comprises the steps:

1. Bleaching process: put fresh flowers in an anhydrous ethanol solution containing hydrogen peroxide and bleach for 1 hour, and the volume ratio of the hydrogen peroxide to anhydrous ethanol is 1:5;

2. Dyeing and setting process: dyeing and setting with 0.5% of the mass of fresh flowers, dyeing agent and ethanol mixed solution for 2 hours, the dye is a cationic dye or a solvent dye, and the setting agent is composed of polyethylene glycol PEG600 and polypropylene glycol PPG1000 Obtained by compounding, the quality of the fixing agent and ethanol mixed solution is 55 times that of fresh flowers, and the mass ratio of the fixing agent and ethanol is 1:4;

3. Drying process: drying the dyed and finalized flowers at 60°C.

The fresh flowers can be preserved for 24 months in a clean environment after the above-mentioned dyeing and setting process.
