Description
Technical field
The present invention relates to the methods that vegetable colour is produced using red sawdust.
Background technique
Petrochemistry dyestuff is derived from petroleum, and Petroleum refining product is in production chemical dye intermediate such as H acid etc. to environment
Pollute it is extremely serious, while by synthesize among chemical dye during chemical dye and high pollution, high carbon emission.And plant contaminates
Material is that absorbing carbon dioxide just can be carried out photosynthesis during its spontaneous growth, this produces discharge titanium dioxide with chemical dye
Carbon is opposite process, therefore vegetable colour more low-carbon, environmental protection.And traditional phytochrome is all in 100 degree of water below
Or ethyl alcohol equal solvent is added and extracts, therefore the dye uptake of traditional phytochrome is low, WASHING COLOR FASTNESS is also low.
Summary of the invention
The purpose of the present invention is overcoming deficiency in the prior art, provides using red sawdust and produce the side of vegetable colour
Method.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The method that vegetable colour is produced using red sawdust, is included the following steps:
Step a: feeding: the red wooden sawdust of yellowish red color to brownish red is chosen；
Step b: it impregnates: the red wooden sawdust of the yellowish red color of selection to brownish red being put into fermentation vat, and into fermentation vat
Pure water is added, impregnates 20 minutes at room temperature, then takes out the red wooden sawdust and soaking water after impregnating；
Step d: extract for the first time: by after immersion the red wooden sawdust and soaking water be added in high pressure stainless steel equipment, and
Green grapes are added into high pressure stainless steel equipment and extract solution, angle acid extraction solution, then carries out first time heating, then carries out
It extracts for the first time, the red wooden sawdust after extracting first time after the completion of extracting for the first time takes out, and first time extracting solution is stayed in height
It presses in stainless steel equipment；
Step e: second extracts: the yellowish red color chosen in step a being added in the high pressure stainless steel equipment into step d extremely
Then the red wooden sawdust of brownish red is added green grapes and extracts solution, angle acid extraction solution, then carries out heating for second, then
It carries out second to extract, takes out second of extracting solution after the completion of second of extraction；
Step f: fermentation: second of extracting solution is cooled down, filtered fluid is then obtained by filtration, then by the closed guarantor of filtered fluid
It deposits, is then fermented to obtain the dyestuff with dark brown suspended matter.
Preferably, the temperature of the first time heating and second of heating is all 120-130 DEG C.
Preferably, the time that the first time extracts is 50-60 minutes, described second time extracted is 50-70
Minute.
Preferably, the red wooden sawdust of the yellowish red color to brownish red is the red wood with the wooden red wooden sawdust or core
Sawdust.
Preferably, the temperature of the closed preservation is 20-35 DEG C, the time of the closed preservation is 3~10 days.
Preferably, in the step b, the weight ratio of the red wooden sawdust of pure water and yellowish red color to brownish red is 1:9-1:
Between 11.
Preferably, the green grapes extract the concentration of solution between 0.2%-0.6%, the angle acid extracts solution
Concentration is between 0.1%-0.5%.
The manufacture craft that the green grapes extract solution includes the following steps:
Step s1: taking green grapes, pure water to be added in container, and the weight ratio of the green grapes and pure water is 1:3；Step
Rapid s2: green grapes are blended, and are then warming up to 70 DEG C, are then kept the temperature and filter after sixty minutes, and obtained filtrate is green grapes extraction
Solution.
The manufacture craft that the angle acid extracts solution includes the following steps:
