Abstract
The invention provides a method for preparing sophora japonica plant dyes, which comprises the steps: sophora japonica woods are cut into a plurality of 1.5cm raw materials, the sophora japonica raw materials are input into a container with water to ferment for 2-3 days, and then are smashed into plant powder below 100 meshes through a pulverizer, the plant powder is placed into an extracting tank, and is mixed with ethanol solution with the concentration of 60% to stir for 1.5 hours and extract natural dye solution, the radio of sophora japonica blades and the ethanol solution is 1:10, and the natural dye solution is filtered to remove slag and obtain dye solution and filter slag. The filter slag is added into the ethanol solution with the concentration of 60% to extract again, evaporated gas is condensed to return flow by adopting a condenser pipe, is continuously extracted for 30 minutes at every time, the obtained dye solution is mixed with the dye solution which is obtained in a step 2 to obtain dye extracting solution, the dye extracting solution is dried and concentrated for 35 minutes through a rotary evaporator to make into dye concentrated solution, the dye concentrated solution is dried through high-speed centrifugal spray to make into natural dye powder. The method for preparing sophora japonica plant dyes is simple in production process, and can conveniently transport, store and produce prepared powder dye.
Description
Technical field
The present invention relates to chemical dyestuff technical field, be specifically related to a kind of preparation method of sophora flower vegetable dye.
Background technology
Along with the raising of people's living standard, quality of life and living environment are more and more paid attention to, the biological degradation of natural plant dye self energy, do not affect environment, vegetable dye originating species, can expand plantation, continuous production, and it is applied to textile dyeing, there is significant Social benefit and economic benefit.Sophora flower contains pigment, is a kind of well Pure natural dye.
Summary of the invention
The invention provides a kind of preparation method of sophora flower vegetable dye, make its technique simple, production efficiency is high, easily extracts the natural plant dye with dyeing function.
The technical scheme that the preparation method of a kind of sophora flower of the present invention vegetable dye adopts is: a kind of preparation method of sophora flower vegetable dye, comprise the following steps: a kind of preparation method of sophora flower vegetable dye, obtain according to the following steps: step 1: raw material sophora flower timber being cut into some 1.5 centimetres of sizes, sophora flower raw material is dropped in the container be filled with water the 2-3 days that ferments, then be ground into plant powder with pulverizer; Step 2: plant powder is placed in extractor, adds the ethanolic soln that concentration is 60%, and stir and extract natural dye liquor, sophora flower blade is 1:10 with the ratio of ethanolic soln, namely obtains dye solution and filter residue after filter and remove residue; Step 3: filter residue is added concentration be 60% ethanolic soln again extract, adopt prolong will the condensation of gas backflow of evaporation, each to extract 30 minutes continuously, the dye solution obtained in the dye solution obtained and step 2 be mixed to get dyestuff extracting solution; Step 4: dyestuff extracting solution is concentrated by Rotary Evaporators drying, makes dye concentrated solution; Step 5: by dye concentrated solution through hig h-speed centrifugal spray drying, makes natural dye powder.
Further, the churning time of plant powder in extractor is 1.5 hours.
Further, plant powder is below 100 orders.
Further, dyestuff extracting solution is 35 minutes at the dry concentration time of Rotary Evaporators.
The invention has the beneficial effects as follows: raw material sources are convenient, and production technique is simple; Be prepared into powder dye, be convenient to transport, store and produce, production efficiency is high.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
The preparation method of a kind of sophora flower vegetable dye of the present invention, comprises the following steps:
Step 1: raw material sophora flower timber being cut into some 1.5 centimetres of sizes, drops in the container be filled with water the 2-3 days that ferments, then is ground into the plant powder of below 100 orders with pulverizer by sophora flower raw material;
Step 2: plant powder is placed in extractor, adds the ethanolic soln that concentration is 60%, and stir and extract natural dye liquor in 1.5 hours, sophora flower blade is 1:10 with the ratio of ethanolic soln, namely obtains dye solution and filter residue after filter and remove residue;
Step 3: filter residue is added concentration be 60% ethanolic soln again extract, adopt prolong will the condensation of gas backflow of evaporation, each to extract 30 minutes continuously, the dye solution obtained in the dye solution obtained and step 2 be mixed to get dyestuff extracting solution;
Step 4: by dyestuff extracting solution by concentrated 35 minutes of Rotary Evaporators drying, make dye concentrated solution;
Step 5: by dye concentrated solution through hig h-speed centrifugal spray drying, makes natural dye powder.
In sum, the invention has the beneficial effects as follows: raw material sources are convenient, and production technique is simple; Be prepared into powder dye, be convenient to transport, store and produce, production efficiency is high.
