The invention discloses a high-temperature high-pressure gas-liquid dyeing machine and a control method thereof. The high-temperature high-pressure gas-liquid dyeing machine comprises a main cylinder, a cloth lifting wheel, an airflow nozzle, a dyeing liquid nozzle, a heat exchanger, a main dyeing liquid pump and a fan component, and the airflow nozzle and the dyeing liquid nozzle are separated and can conveniently and quickly control parameters of airflow and dyeing liquid flow independently according to characteristics of to-be-dyed fabric. The airflow nozzle is positioned in front of the dyeing liquid nozzle, so that the wound fabric can be blown fluffily by high-pressure airflow, dyeing liquid spraying and penetrating is performed afterwards, using efficiency of dyeing liquid is improved greatly, leveling performance and dye yield rate of dyeing are improved, dyeing time is reduced, total consumption of auxiliaries and dye is lowered, and total COD quantity is lowered effectively. By the high-temperature high-pressure gas-liquid dyeing machine, more uniformity in dyeing can be realized, energy consumption of a gas-liquid split-flow dyeing machine is lowered, and the objectives of energy conservation and environment protection are achieved.

The invention provides a hematoxylin eosin staining solution, comprising a hematoxylin staining solution and an eosin staining solution, wherein the hematoxylin staining solution comprises hematoxylin, an alumium salt, an oxidizing agent, benzalkonium chloride, an alcohol, a weak acid and water; the eosin staining solution comprises eosin, Biebrich scarlet, flame red B, water and ethanol. The invention also provides a preparation method of the hematoxylin eosin staining solution, and a dyeing method thereof. When the hematoxylin eosin staining solution provided by the invention is used for dyeing slices, the effects of clear background, distinct gradation, good dyeing effect, easy slice reading, not easy fading and convenience for long-term storage can be achieved.

The invention discloses an indigo-blue bamboo weaving handicraft, comprising the following steps: S1, bamboo material selection, selection of purple bamboo that has grown for more than two years and good growth, and the diameter of the purple bamboo needs to be between 3-5cm; S2, bamboo material processing, for Bamboo cutting, remove the parts that are not suitable for bamboo pieces at both ends of the bamboo, then polish the outer surface of the bamboo, scrape off the bamboo knots and bamboo hairs, process the outer surface of the bamboo into a smooth surface, and finally cut the bamboo again, the bamboo Bamboo slices cut into thin strips The present invention relates to the technical field of bamboo weaving. The indigo blue bamboo woven handicraft and its dyeing device make the texture of the bamboo pieces more natural and rich in color through wood wax oil. By exposing the bamboo pieces to the sun and rain, and then exposing them to the sun, the moisture in the bamboo pieces can be fully removed, so as to ensure the service life of the bamboo woven fabrics and avoid Bamboo woven fabrics rot due to moisture, and then use dyes with insect repellents to avoid insects and further improve the service life of bamboo woven fabrics.
