Abstract
The invention belongs to the field of research of natural plant extracts, and particularly relates to a pterocarpus santalinus extract and a preparation method and application thereof. The pterocarpus santalinus extract is prepared by adopting an ethanol extracted method. The method comprises the following steps: washing pterocarpus santalinus, airing, and mechanically crushing the pterocarpus santalinus; adding to alkaline ethanol water, refluxing and extracting for 2 hours, and filtering; and carrying out spray drying on filtrate, so as to obtain pterocarpus santalinus extract powder. The pterocarpus santalinus extract can be used for dyeing textile as a natural dye, and has a good dyeing effect.
Description
Technical field
The invention belongs to natural plant extracts research field, particularly the extract and preparation method thereof of a kind of leaflet red sandalwood and application.
Background technology
In people today to environmental issue pay attention to day by day, more and more natural plant resource is widely used, vegetable dye is also used in fabric dyeing process more and more, but there is quite a few plant milk extract dyestuff to the upper dye poor effect of textiles, as color and luster is not dark, colour purity is not high, poor visual effect etc.Therefore the dyeing much relating to vegetable dye only rests on the experimental study stage, also really cannot replace chemical synthetic dye, realizes the industrialization of natural dyeing technique.
The timber kind belonging to Pterocarpus is various, but the red sandalwood of generally acknowledging in plant educational circles only has one, " red sandalwood ", and be commonly called as " leaflet red sandalwood ", Classification system is P.santalinus.Red sandalwood is fine work in red sandalwood, and density is large, pinhole is little is its outstanding feature, and wood is highly stable, not easily strain cracking.Red sandalwood fecund is in the torrid zone, subtropics virgin forest, optimum with the red sandalwood that Mysore nation of India area produces.Compendium of Material Medica record: leaflet red sandalwood can be stopped blooding, pain relieving, adjustment qi and blood.Leaflet red sandalwood can give out the material that one is called " wooden oxygen ", and this material can not only play the effect of tranquilization and refreshment, and life-time service can also promote that cell reproduces, the appearance of Ginseng Extract.Leaflet red sandalwood cured leaf is made the pillow of boudoir, have certain effect of releiving to gastroenteropathy.But so far, to the research of leaflet rosewood extractive and application aspect thereof or fewer.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of leaflet rosewood extractive and relevant extracting method, and about this leaflet rosewood extractive as dyestuff, the application in textile dyeing.
For solving the problems of the technologies described above, the technical solution used in the present invention is: adopt the method for extraction using alcohol to extract leaflet red sandalwood, concrete steps are as follows:
Granular leaflet red sandalwood is cleaned, dries, mechanical disintegration to 20-50 order, obtain leaflet red sandalwood crushed material, again leaflet red sandalwood crushed material is joined pH value 7-9, concentration of volume percent is in 50-85% aqueous ethanolic solution, obtain extraction system, the mass ratio of leaflet red sandalwood crushed material and aqueous ethanolic solution is 1: 35; Described extraction system is warming up to 95 DEG C of refluxing extraction 2h; Filter, the filtrate obtained carried out spraying dry, obtains leaflet rosewood extractive powder,
Wherein, the pH value of above-mentioned aqueous ethanolic solution is regulated by sodium bicarbonate or sodium carbonate;
Above-mentioned spray-dired inlet temperature is 140 DEG C, and air outlet temperature is 80 DEG C.
Present invention also offers the above-mentioned leaflet rosewood extractive of a kind of employing as natural dyestuff, fabric is carried out to the technique of upper dye, concrete steps are:
Leaflet rosewood extractive powder is dissolved in ethanol, every 5g leaflet rosewood extractive powder dissolution is in 1 ~ 2ml ethanol, add deionized water dispersion again, obtain uniform diluent, and to control the mass concentration of leaflet rosewood extractive in diluent be 0.8-1.6%, and the pH value of diluent is regulated to be 4-6; Be immersed in by fabric in the diluent of gained, dye to fabric, controlling dyeing condition is that bath raio is 1:10-30, and dyeing temperature is 95 DEG C, and dyeing time is 20-40 minutes, washes and dry after dyeing, obtains DYED FABRICS.
Present invention also offers the application of a kind of leaflet rosewood extractive as UV light absorber, using leaflet rosewood extractive as natural dyestuff, to giving fabric uvioresistant performance after textile dyeing;
Present invention also offers a kind of leaflet rosewood extractive as natural antibacterial staining agent, while dyeing to fabric, carry out antimicrobial treatment to fabric, bacterium is here streptococcus aureus;
Present invention also offers a kind of leaflet rosewood extractive and preventing and treating the application in anthrax: leaflet rosewood extractive powder is made into the aqueous solution that Solute mass fraction is 8-10%, fruit is sprayed, the good effect of preventing and treating anthrax can be played, or using fruit as controlling object, using being wrapped on described fruit based on leaflet rosewood extractive as the DYED FABRICS of dyestuff, the effect of preventing and treating anthrax can be played.
Beneficial effect of the present invention is: the present invention adopts the method for ethanol-extracted to prepare leaflet rosewood extractive, simple process; Leaflet rosewood extractive is dyeed as natural dyestuff to fabric, avoid the infringement of organic chemistry dyestuff to human body skin, and there is excellent dye uptake and fabulous fastness, and color is very pure after upper dye, and floodlight effect is obvious, the cloth being suitable as high-grade clothing uses, and dyeing adapts to suitability for industrialized production; Antibacterial fabric performance, uvioresistant performance is given after dyeing, and the performance of control fruit anthrax.
