Abstract
The invention discloses a preparation method for walnut peel vegetable dye, which particularly relates to a production method for Rhamnus utilis vegetable dye and belongs to the technical field of the textile dyeing technology. The preparation method for the walnut peel vegetable dye comprises the following technical processes: taking a walnut peel raw material, cleaning, drying, smashing, putting into an extracting tank, adding ethanol solution of which the concentration is 20-30%, and stirring for 3.5-4h to obtain mixed liquor A, wherein the ratio of the walnut peel raw material to the ethanol solution is 1:15-1:20; filtering the mixed liquor A to remove slags to obtain dye liquid A and filter residue A; heating the dye liquid A to 65-75DEG C; condensing to obtain the dye concentrated solution A of which the concentration is 30-40%; putting the filter residue A into the extracting tank, and adding acetone solution of which the concentration is 20-30%; stirring for 1-2h to obtain mixed liquor B, wherein the ratio of the filter residue to the acetone solution is 1:10-1:15; and drying dye concentrated solution A and dye concentrated solution B by high-speed centrifugal spraying or a rotary atmometer to obtain the natural dye powder. The preparation method for the walnut peel vegetable dye has the advantages of convenience in raw material source, simple production technology and high production efficiency. Because the walnut peel vegetable dye is prepared into the powdery dye, the walnut peel vegetable dye is very convenient to transport, store and produce, and the production efficiency is high.
Description
Technical field
The present invention relates to the preparation method of Cortex walnut wood dye, specifically the working method of iced green plant dye belongs to textile dyeing Technology field.
Background technology
The Along with people's growth in the living standard is more and more paid attention to quality of life and living environment, the biological degradation of natural plant dye self ability; Do not influence environment; Iced green plant dye source plant can enlarge plantation, continues to produce; And it is applied to textile dyeing, has remarkable social benefit and economic benefit.Cortex walnut, Walnut Leaves contain pigment, are a kind of good pure natural dyestuffs.
Summary of the invention
In view of the defective that prior art exists, the object of the present invention is to provide the preparation method of Cortex walnut wood dye, make its technology simple, production efficiency is high, is convenient to transportation and storage, and easy extraction has the natural plant dye of dyeing function.
For realizing above-mentioned purpose, the technical solution that the present invention adopted is the preparation method of Cortex walnut wood dye, adopts following technological process:
(1), get the Cortex walnut raw material, clean, oven dry is pulverized, and inserts in the extractor, adding concentration is 20% ~ 30% ethanolic soln, stirs and processes mixed liquor A in 3.5 ~ 4 hours, the Cortex walnut raw material is l:15 ~ 1:20 with the ratio of ethanolic soln;
(2), the mixed liquor A filter and remove residue promptly gets dye solution A and filter residue A;
(3), dye solution A is heated to 65 ℃ ~ 75 ℃, be concentrated into concentration and be 30% ~ 40% dye concentrated solution A;
(4), filter residue A inserts in the extractor, adding concentration is 20% ~ 30% acetone soln, stirs and processes mixed liquid B in 1 ~ 2 hour, filter residue is l:10 ~ 1:15 with the ratio of acetone soln;
(5), the mixed liquid B filter and remove residue promptly gets dye solution B and filter residue B;
(3), dye solution B is heated to 65 ℃ ~ 75 ℃, be concentrated into concentration and be 30% ~ 40% dye concentrated solution B;
(6), dye concentrated solution A and dye concentrated solution B is dry through high speed centrifugation spraying or Rotary Evaporators, process natural dye powder.
Spray-drier is dry: the hot-air inlets temperature is 200 ℃ ~ 240 ℃ when cocurrent cooling operation, is 150 ℃ ~ 180 ℃ during counter-current operation, and temperature out is controlled at 60 ℃ ~ 100 ℃ behind the atomization drying.
Rotary Evaporators is dry: vacuum tightness 0.085 MPa, drying temperature are 60 ~ 70 ℃.
After adopting such scheme, compared with prior art have following beneficial effect: raw material sources are convenient, and production technique is simple; Be prepared into powder dye, be convenient to very much transportation, store and produce, production efficiency is high.
