Description
Technical field
The invention belongs to the field of fabric being dyeed, particularly use the natural vegetable dye textile printing technique with natural dye; Simultaneously, the present invention also relates to dyestuff by the natural origin of natural material preparation.
Background technology
The application of natural plant dye has long history, but most of natural plant dyes do not have substantivity or direct less to fiber, and the fabric that is dyeed must rely on mordant just can anchor on the fiber.In traditional mordant dyeing technology, mordant commonly used mostly is greatly and contains the heavy metal ion compound, as Cu, Fe, Cr ion etc.Along with the part kind in the synthetic dyestuffs is forbidden, heavy metal ion content in the textiles also is restricted, for this reason, select for use new mordant to replace traditional heavy metal ion, be an important content developing the ecological processing of textiles at present (1. Wang Ji China etc., the application of natural dye and progress thereof, dye industry, the 32nd the 5th phase of volume, nineteen ninety-five; 2. open and build ripple etc., mordant dyeing of cotton fabric with natural dyestuffs, printing and dyeing, 2005 No. 16).Therefore, in the dyeing of natural plant dye, select the mordant of the native compound pollution-free, that consumption is low for use as natural plant dye dyeing, both can satisfy the required fastness requirement of production environmental protection textiles, (1. woods is carefully tender etc., the mordant dyeing application study of rare earth in vegetable colour dyeing can to avoid the pollution that traditional mordant brings environment again, printing and dyeing assistant, the 19th volume, the 1st phase, in February, 2002; 2. poplar east is clean etc., and madder is in the natural fabric Application of Dyeing, silk, 2000 the 12nd phases).
Summary of the invention
At the deficiencies in the prior art, the present invention aims to provide a kind of natural mordant and play the mordant dyeing effect when dyeing with natural plant dye, and the required technical matters of this mordant dyeing.
Present natural plant dye mainly dyes by infusion process, and in order to improve the dyefastness of product, generally uses mordant.Mordant is most of, and its mordant dyeing mechanism is in the mordant dyeing processing procedure in order to contain the compound (as CN1240808) of metals such as aluminium, iron, copper, calcium, chromium, and vegetable colour-mordant-fiber three forms the stable comple metal-complexing.
About loess, it is based on quartzy (accounting for 50%), feldspar (20%) and carbonate mineral, and calcium carbonate content accounts for about 10%.The chemical composition of loess is preponderated with SiO2, is Al2O3, CaO secondly, is Fe once more
2O
3, MgO, K2O, Na2O, FeO and TiO2 (Korea S special permission 10-0321991).Each metal ion species is many in the loess, and the generation complex compound that reacts of the ion in they and dyestuff and the fabric strengthens the absorption between dyestuff and the fabric, thereby improves the dye-uptake of natural dye.The chemical composition of laterite is similar with loess, and its difference is for to preponderate with SiO2, secondly be Al2O3,, Fe
2O
3, be CaO once more, MgO, K2O, Na2O, FeO and TiO2.
For loess, it is displaing yellow why, is because the more cause of Ca ion ratio.The Ca ion has played function served as bridge in the mordant dyeing process, the complex structure of its formation is stable.With the fabric of loess powder mordant dyeing, its form and aspect change little, bright.And for laterite, more because of containing the Fe ion, so show red.Iron ion in the laterite is the migration metal ion, and its formed inner orbit type complex compound is very stable, and form and aspect alter a great deal before and after the mordant dyeing.
Yellow (red) native powder as its mordant dying technical matters of mordant of natural plant dye is:
1) yellow (red) native powder is to natural plant dye mordant dying method: can be divided into three kinds:
(1) first mordant dyeing technology
Natural plants dyes material → water or ethanol extraction → distillation and makes concentrate → the join native mordant dyeing → dyeing of dye liquor → Huang (red) → washing → oven dry
(2) back mordant dyeing technology
Natural plants dyes material → water or ethanol extraction → distillation and makes concentrate → the join native mordant dyeing → washing of dye liquor → dyeing → Huang (red) → oven dry
(3) mix mordant dyeing technology
Natural plants dyes material → water or ethanol extraction → distillation and makes that concentrate → joining dye liquor → dyestuff/Huang (red) soil mixes mordant dyeing → washing → oven dry
2) the refining purifying technique of yellow (red) native powder
(1) with hard thing the native block of Huang (red) is pulverized.
(2) with 50～100 eye mesh screens loess, laterite are screened, stay thinner Huang (red) soil particle.(3) water separates with the impurity in the soil dissolving of Huang (red) soil particle, stirring with soil block.
(4) remove impurity floating in the solution.
(5) fully stir yellow (red) native water dispersion solution, use 100～300 eye mesh screens that Huang (red) soil is screened, filters simultaneously, obtain the native turbid liquid of fine Huang (red).
(6) leave standstill, make Huang (red) soil precipitation, the water on upper strata is poured out.Obtain Huang (red) soil of wet shape.
(7) cover ventilative cover, the Huang that will wet (red) soil dries in the sun.
(8) use preceding block to grind, obtain the native powder of pure Huang (red) yellow (red) soil.
3) yellow (red) native powder is to natural plant dye mordant dying technology:
Make usage basic identical with mordant commonly used, its difference is in the mordant dyeing treatment process, stir the native dispersion liquid of Huang (red), and it is uniformly dispersed, and finally obtains the fabric of even dyeing.
Natural plants dyes material → water or ethanol extraction → distillation and makes concentrate → join dye liquor → first mordant dyeing or back mordant dyeing or mix mordant dyeing → washing → oven dry
Dyeing temperature: 50～100 ℃, the time: 10～60min; Washing temperature: 40～60 ℃; Yellow (red) native addition: 5g/L～50g/L, bake out temperature: 80～100 ℃.Wherein with 40～80 ℃ of first or back mordant dyeing temperature, the time, 10～30min was advisable, and other conditions are the same.
Its fibrous material of natural fabric dyed textiles that yellow (red) native powder mordant dyeing is suitable for is:
Natural fabric: cotton, fiber crops, wool, silk etc.;
Chemical fibre: terylene, nylon, acrylic fibers, viscose glue etc.;
Various novel, green fibers: day silk, model, fibre and soya, bamboo fibre etc.;
Comprise the nonwoven fabric made from above-mentioned fiber, and leather, specialties.
The present invention is applicable to apparel textile, textiless such as home-use textiles and various decoration, packing.Owing between natural dye, mordant and the fiber three, the metal-complexing effect can take place, so final products have dyefastness such as higher washing, friction.Washable, fastness to rubbing test result: washing fastness: 4 grades; 3～4 grades of dry fastnesses; 2～3 grades of fastness to wet rubbings.
Compared with prior art, the characteristics that the present invention has are: (1) utilizes the native powder of Huang existing in the Nature (red) as mordant, has formulated a kind of existing ecology, safe, nontoxic, and the natural dye dying fabric of health-care effect is arranged again.(2) dyeing is simple, and common dyeing is suitable for the production of product of the present invention fully.[3] inexpensive.
