Description
Technical field
The present invention relates to textile dyestuff and Application Areas thereof, particularly relate to the preparation method and the application thereof of a Madhuca hainanensis chunetHow natural dye.
Background technology
Modern science and technology and rapid development of social economy improve constantly the human living standard, and quality of the life is improved greatly, and health has become the problem that the world today pays close attention to the most.Natural dyestuff is taken from natural phant, refines through operations such as pulverizing, immersion, boilings to form, and is harmless to HUMAN HEALTH, good with Environmental compatibility, biodegradable, has the superiority that synthetic dyestuff hardly match.Natural dye dying fabric color nature, graceful, the unique uniqueness of tone, except that the dyeing function, the part natural dyestuff also has the medicinal health-care function.
Sub-capital wood have another name called Wood of Chinese Redbud (latin name: MadhucahainanensisChunetHow), the Sapotaceae aiphyllium.The wooden sorrel that is, texture is straight, and structure is dense, and material is tough and tensile, and is very heavy, do not shrink after the drying, few cracking, the corrosion resistant ability is strong, is difficult for damaging by worms, and is medium-to-high grade timber, is suitable for most and does material such as shipbuilding, bridge, vehicle, mechanical implement and hydro project.
Studies show that: sub-capital pigment content height, maximum absorption wavelength can be used as a kind of hypernic textiles are dyeed about 500nm; Moreover, dyeing back textiles also has excellent bacteria resistance function, can be used to the development functionality textiles.About preparation method, dyeing and the research of the anti-microbial property on textiles thereof of sub-capital wood natural dyestuff, not seeing both at home and abroad has report at present.
Summary of the invention
The objective of the invention is in order to fill up the blank of above-mentioned background technology, a kind of method and application thereof that utilizes sub-capital wood wood chip or tankage to prepare natural dyestuff is provided; The method that provides should have technology simple, can make full use of resource, low-cost characteristics, applied fabric is answered environmental protection, is had anti-microbial property.
Technical scheme provided by the invention is: the preparation method of a Madhuca hainanensis chunetHow natural dye may further comprise the steps:
(1) with the wood chip or tankage mechanical disintegration to 10～100 order of sub-capital wood;
(2) take by weighing 1 kilogram of sub-capital wood powder and add refluxing extraction in the aqueous ethanolic solution, the weight ratio of sub-capital wood powder and aqueous ethanolic solution is 1: 20～50; In the aqueous ethanolic solution, alcohol concn is 30～70%, concentration of sodium carbonate 1～5 grams per liter, and all the other are water;
(3) liquid of refluxing extraction is warming up to 40～80 ℃, and insulation 80～100min removes solids after the filtration, and excess evaporation concentration to 5 liter obtains sub-capital wood natural dyestuff.
Described evaporation concentration is underpressure distillation.
Sub-capital provided by the invention wood natural dyestuff is applied to fabric is carried out substantive dyeing; Wherein:
Under the condition without mordant, adopt sub-capital wood natural dyestuff can dye orange-red real silk, wool product, polyamide fibre goods russet; Under mordant dyeing condition after the metallic aluminium salt, can dye filemot real silk, wool product.Under mordant dyeing condition behind the metal ferrous salt, can dye real silk, the wool product of purple; At Neodymium trichloride with bathing under the mordant dyeing condition, can dye khaki real silk, wool product.
Sub-capital provided by the invention wood natural dyestuff is applied to fabric is carried out antimicrobial treatment; May further comprise the steps:
(1) the wooden treatment solution in sub-capital is formed by sub-capital wood natural dyestuff and water configuration, and sub-capital wood natural dyestuff accounts for 30～50% of whole dye liquor weight, regulates treatment solution pH value 4～6;
(2) pollutant of real silk or wool quality being put into sub-capital wood treatment solution handles; Control condition is as follows: the ratio 1: 10～50 of pollutant weight and the volume of treatment solution, 80～100 ℃ of temperature, time 60～80min;
(3) dye complete, the washing, the oven dry.
Beneficial effect of the present invention is: the present invention extracts hypernic from sub-capital wood wood chip or wood working tankage, and real silk, wool and polyamide fabric dyeed, colour fastness is better, the dye uptake height, and the dyeing back uses the environmental protection mordant to handle can increase chromatogram; Simultaneously real silk, the wool fabric after the wood dyeing of sub-capital has excellent germ resistance, to streptococcus aureus, colibacillary bacteriostasis rate reach 95% respectively, more than 96%, and washing fastness is good; Color and luster was soft after fabric adopted sub-capital wood natural dye dying, wore safety, did not have carcinogenic, teratogenesis or caused allergic reaction.And it is simple to utilize sub-capital wood tankage or wood chip to prepare dye technology, low price, and steady quality has also made full use of resource, and market outlook will be very wide.
