Abstract
The invention discloses a method for preparing natural dye through walnut green husk waste and belongs to the field of natural dye. According to the method, natural dye is extracted from the walnut green husk waste, the preparation process is simple, and no environmental pollution is caused; fabric dyed by the extracted natural dye is even in color and luster, the dyeing rate reaches as high as 85%, and the dyed fabric cannot cause cancer, or cause deformation or cause an anaphylactic reaction; the compatibility with the biological environment is good, and biodegradation is achieved; the walnut green husk raw materials are rich, quality is stable, and the method is worthy of large-scale application and popularization.
Description
Technical field
The present invention relates to natural dyestuff field, particularly a kind of method utilizing green peel of walnut waste to prepare natural dyestuff.
Background content
Modern science and technology and socioeconomic develop rapidly, the standard of living of people is improved constantly, and quality of the life is improved greatly, and human health has become the problem that the world today pays close attention to the most.In environmental protection trend of today, weaving and clothes tend to naturalization, and people's yearning goes back to nature, also more and more urgent to the demand of green safety textiles.And after natural dyestuff experience for many years unfrequented, be again subject to the favor of people.Therefore, development and utilization natural phant is benefited for the mankind, has been current development trend.
From green production angle, vegetable dye has the superiority that synthetic dyestuff hardly match, it is for raw material with plants such as the distinctive herbal medicine of China, flowers, tealeaves, through the natural plant dyestuff that the operations such as pulverizing, immersion, boiling are refined, be harmful to human health, good with Environmental compatibility, free from environmental pollution, biodegradable.With the fabric of natural dye dying, both met environmental protection, ecological Production requirement, and turn avoid the infringement of synthetic dyestuff to HUMAN HEALTH, meet the clothes requirement of health, functionalization.
Annual 8, September just produces a large amount of walnut husks in walnut results in season, i.e. green peel of walnut, because green peel of walnut alkalescence is comparatively strong, can not be used as feed, directly can not make fertilizer, it is often arbitrarily stacked in field, the edge of a field, roadside or limes marginis by peasant and some retailers; Once rainy or rascal immersion, the brown waste water of a large amount of alkalescence will be produced, pollute soil and the waters of green peel of walnut periphery, cause environmental pollution.
In current green peel of walnut, the extraction and isolation of chemical composition and Components identification research make some progress, research shows that in green peel of walnut, some composition extraction can be used for curing the disease, some composition can be applicable to agricultural chemicals, and the pigment in rascal can be used as foodstuff additive etc.
Patent CN1912011A discloses a kind of method extracting natural dyestuff from walnut husk, but pre-treatment cost is higher, process is loaded down with trivial details problem that this method exists equally, and leaching liquid uses ethanol liquid, while increasing cost further, also there is certain detrimentally affect to environment.
Summary of the invention
The object of the present invention is to provide a kind of method utilizing green peel of walnut waste to prepare natural dyestuff.
In order to realize object of the present invention, the technical scheme taked is as follows:
Utilize green peel of walnut waste to prepare the method for natural dyestuff, comprise the following steps:
1, select fine day, dehydration is tanned by the sun in the tiling of the green peel of walnut of collection, and treat that green peel of walnut dries (water content is low to moderate less than 8%), after color becomes black, mechanical disintegration, to 20-80 order, obtains green peel of walnut powder;
2, the green peel of walnut powder after pulverizing being successively dipped in volume fraction is carry out gradient elution in the aqueous ethanolic solution of 75%, 80%, 85%, 95%, feed liquid mass ratio is respectively 1:2,1:4,1:8,1:10, normal temperature soaks 1h, 2h, 4h, 6h respectively, filter, merge vat liquor, obtain natural dyestuff stoste;
3, the natural dyestuff stoste of extraction is concentrated into paste dyestuff;
4, paste dyestuff is cured, pulverizes, obtain Powdered natural dyestuff.
The biological beneficial effect of the present invention:
The present invention utilizes in green peel of walnut waste and extracts natural dyestuff, and preparation process is simple and can not cause environmental pollution; The fabric color of the natural dye dying that the present invention extracts is even, and upper dyestuff is up to 85%, and after dyeing, fabric can not carcinogenic, teratogenesis or cause allergic reaction again; Good to consistency with ecotope, biodegradable; And green peel of walnut abundant raw material, steady quality, its market outlook will be very wide.
