Embodiment 1
[0043] A kind of poplar dyeing method, comprises the following steps:
[0044] (1) Prepare the dye solution: put cochineal in a container, add potassium aluminum sulfate dodecahydrate, add water at 60°C, stir, keep warm at 50°C, and dissolve to prepare a dye solution with a mass percentage concentration of 3%. The bath ratio is 1:3, the mass percentage concentration of cochineal red is 2%, the mass percentage concentration of potassium aluminum sulfate dodecahydrate is 1%, and the pH value of the dyeing solution is adjusted to 6.5-7 with disodium hydrogen phosphate or citric acid ;
[0045] (2) Soak poplar wood with a thickness of 20mm in the dye solution prepared in step (1), keep the temperature of the water bath at 60°C, take it out after soaking for 3h under the action of ultrasonic waves with a power of 200w, then put it into the magnetic field, and change the magnetic field Intensity and direction, the intensity range of the magnetic field is 0-20mT;

Embodiment 2
[0054] A kind of dyeing method of radiata pine, comprises the following steps:
[0055] (1) Prepare the dyeing solution: put chrysanthemum yellow in a container, add potassium aluminum sulfate dodecahydrate, add 75°C warm water to moisten it, stir evenly, keep warm at 60°C, dissolve, and prepare a dyeing solution with a mass percentage concentration of 11%. When the bath ratio is 1:6, the mass percentage concentration of chrysanthemum yellow is 4%, the mass percentage concentration of potassium aluminum sulfate dodecahydrate is 7%, and the pH value of the adjusted dye is neutral or weakly acidic;
[0056] (2) Soak radiata pine with a thickness of 20mm in the dyeing solution prepared in step (1), keep the temperature of the water bath at 75°C, take it out after soaking for 4h under the action of ultrasonic waves with a power of 400w, put it into the magnetic field again, and change the magnetic field Intensity and direction, the intensity range of the magnetic field is 20-40mT;...
Embodiment 3
[0065] A kind of poplar dyeing method, comprises the following steps:
[0066] (1) Configure the dye solution: put tartrazine in a container, add potassium aluminum sulfate dodecahydrate, add 72°C water, stir, keep warm at 55°C, dissolve, and prepare a dye solution with a mass percentage concentration of 7%. The bath ratio is 1:4, the mass percentage concentration of tartrazine is 3%, and the mass percentage concentration of potassium aluminum sulfate dodecahydrate is 4%;
[0067] (2) Soak poplar wood with a thickness of 21mm in the dye solution prepared in step (1), keep the temperature of the water bath at 72°C, take it out after soaking for 5h under the action of ultrasonic waves with a power of 300w, then put it into the magnetic field, and change the magnetic field Intensity and direction, the intensity of the magnetic field is 41-60mT;
[0068] (3) taking out the poplar wood obtained in the step (2) and stacking it for 6d at normal temperature and pressure;
[0069] (4...
