Abstract
The invention provides a preparation method of a Salvia japonica Thunb. vegetable dye. The preparation method includes the steps of firstly, selecting Salvia japonica Thunb., picking petals thereof, and using a traditional Chinese medicine grinder for grinding the petals into 10-50-mesh vegetable powder; secondly, putting the vegetable powder into an extraction tank, adding 50% ethanol water with stirring for 3.5 hours, conducting ultrasonic wave treatment to extract natural dye liquor at 40-55 DEG C, and filtering to remove residues so as to obtain dye liquor, wherein the ratio of the vegetable powder to a solvent is 1 to 18; thirdly, heating the dye liquor to 65-70 DEG C, and concentrating to obtain 40-50% concentrated dye liquor; fourthly, subjecting the concentrated dye liquor to reduced-pressure evaporation through a rotary evaporator prior to evaporation drying so as to obtain natural dye powder. The preparation method of the Salvia japonica Thunb. vegetable dye has the advantages of convenience in obtaining of the raw materials, simple production technology and high production efficiency. By being prepared into the dye powder, the Salvia japonica Thunb. vegetable dye is convenient to produce, store and transport.
Description
Technical field
The present invention relates to chemical dyestuff technical field is and in particular to a kind of preparation method of clary dyestuff.
Background technology
With the raising of people's living standard, quality of life and living environment are increasingly paid attention to, natural plant dye is certainly
Body energy biodegradation, does not affect environment, vegetable colour originating species, can expand plantation, continuous production, and it is applied to spin
Fabric dyes, and has significant Social benefit and economic benefit.Salvia japonica Thunb. contains pigment, is a kind of good Pure natural dye.
Content of the invention
The present invention provides a kind of preparation method of clary dyestuff so as to process is simple, production efficiency height, easily extracts
There is the natural plant dye of dyeing function.
A kind of preparation method of present invention clary dyestuff be the technical scheme is that a kind of clary dye
The preparation method of material, comprises the following steps: step 1: chooses Salvia japonica Thunb., plucks its petal, be ground into 10-50 mesh with Chinese medicine grinder
Plant powder；Step 2: plant powder is placed in extraction pot, adds 50% ethanol water, 3.5 hours heating 40-55 of stirring
Carry out ultrasonic Treatment under the conditions of DEG C and extract natural dye liquor, plant powder is 1:18 with the ratio of solvent, obtains final product dye after filter and remove residue
Feed liquid；Step 3: dye solution is heated to 65-70 DEG C, is concentrated into the dye concentrated solution that concentration is 40%-50%；Step 4: by dyestuff
The rotated evaporation under reduced pressure of concentrated solution evaporates, and volatile dry makes natural dye powder.
Further, Rotary Evaporators are dried: 0.085 MPa of vacuum, and baking temperature is 60-65 DEG C.
The invention has the beneficial effects as follows: raw material sources are convenient, simple production process；It is prepared into powder dye, be readily transported,
Storage and production, production efficiency is high.
Specific embodiment
A kind of preparation method of present invention clary dyestuff, comprises the following steps:
Step 1: choose Salvia japonica Thunb., pluck its petal, be ground into the plant powder of 10-50 mesh with Chinese medicine grinder；
Step 2: plant powder is placed in extraction pot, adds 50% ethanol water, under the conditions of 40-55 DEG C of stirring heating in 3.5 hours
Carry out ultrasonic Treatment and extract natural dye liquor, plant powder is 1:18 with the ratio of solvent, obtains final product dye solution after filter and remove residue；
Step 3: dye solution is heated to 65-70 DEG C, is concentrated into the dye concentrated solution that concentration is 40%-50%；
Step 4: rotated for dye concentrated solution evaporation under reduced pressure is evaporated, volatile dry makes natural dye powder, wherein, rotation
Evaporimeter is dried: 0.085 MPa of vacuum, and baking temperature is 60-65 DEG C.
In sum, the invention has the beneficial effects as follows: raw material sources are convenient, simple production process；It is prepared into powder dye,
It is readily transported, stores and produces, production efficiency is high.
