Abstract

The invention relates to a method for preparing a safflower plant dyestuff and belongs to the technical field of chemical dyestuffs. The method comprises the following steps: selecting 100 parts of safflower, grinding the safflower into powder with a traditional Chinese medicine grinder, and adding the powder into an extracting tank; adding 1 part of cellulose, 1 part of pectinase and 1 part of protease into 2000 parts of an aqueous solution with the pH being 4, stirring under a heating condition, and conducting suction filtration to obtain a dyestuff solution; drying the extracted dyestuff solution for concentration through a rotary evaporator to obtain a dyestuff concentrated solution; drying the dyestuff concentrated solution in a mode of high-speed centrifugal atomization to prepare natural dyestuff powder. The source of raw materials is convenient, and the production process is simple. The prepared powdered dyestuff is convenient to transport, store and produce, and the production efficiency is high.

Description

The preparation method of safflower vegetable dye

Technical field

The present invention relates to the preparation method of safflower vegetable dye, it belongs to chemical dyestuff technical field.

Background technology

Raising along with 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 source plant, can expand plantation, continuous production, and it is applied to textile dyeing, there is significant Social benefit and economic benefit.Safflower contains pigment, is a kind of good pure natural dyestuff.

Summary of the invention

In view of the defect that prior art exists, the object of the present invention is to provide the preparation method of safflower vegetable dye, make its technique simple, production efficiency is high, easily extracts the natural plant dye with dyeing function.

For achieving the above object, the technology used in the present invention solution is the preparation method of safflower vegetable dye, comprises the following steps:

A, choose 100 parts, safflower, with medicinal herb grinder, be ground into powder, be placed in extractor, add 1 part of 1 part of cellulase, 1 part of polygalacturonase, proteolytic enzyme in the aqueous solution of 2000 parts of pH=4, under heating condition, stir, after suction filtration, obtain dye solution;

B, the dye solution extracting be dried and is concentrated by Rotary Evaporators, make dye concentrated solution;

C, by dye concentrated solution through hig h-speed centrifugal spray drying, make natural dye powder.

Described plant powder is 20-80 order.

Described Heating temperature is 40-60 ℃.

Described stirring, the time is 0. 5-4 hour.

Vacuum tightness 0.085 MPa of described Rotary Evaporators, bath temperature is 60 ~ 70 ℃.

Adopt after such scheme, compared with prior art there is 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.
