Abstract
The invention relates to a wool and wool fabric dyeing assistant, its preparation method and application. The dyeing assistant provided in the invention comprises: protease, peptide, and a buffer solution. The protease and the buffer solution are in a mass-volume ratio of 0.01-1g:100ml, the peptide and the buffer solution are in a mass-volume ratio of 0.01-2g:100ml. Application of the dyeing assistant provided in the invention in processing wool and its fabrics includes the steps of: adding the peptide, the protease and 0.4-4% owf of a dye into the buffer solution, and conducting sufficient stirring for dissolving when adding each matter; adding the fur or fur fabric in a bath ratio of 1:10-50, placing the mixture at a temperature of 25-70DEG C for 30-60min, then placing it at a temperature of 70-95DEG C for 10-60min; and carrying out washing to remove the residual dye. The assistant provided in the invention can assist the dye to enter the inside of wool fibers. The dyeing temperature can be reduced, and the bonding strength between the dye and the wool fabric can be enhanced. The dyeing assistant has the advantages of low dyeing temperature, simple operation, strong dye adhesion, high efficiency dye utilization, and environment pollution avoidance.
Description
Technical field
The invention belongs to the textile printing and dyeing field, particularly a kind of hair and textile dyeing auxiliary agent thereof.
Background technology
Wool fibre is one of the most complicated natural fabric of structure, and the surface has scale to cover, and is hydrophobic property, and it is wetting that this has caused dye liquor to be difficult for, and has hindered absorption and the diffusion of dyestuff and is difficult to dye.Dye strength content is high in the dyeing residual liquid, and sewage disposal is difficult.In order to increase dyeing efficient and dye utilization rate, high-temperature dyeing process is generally adopted in wool fabric dyeing at present, and dyeing time is also longer, and energy consumption is high when causing dyeing.This technology does not meet the energy-saving and emission-reduction and the strategy of sustainable development, and particularly along with the development of other industry, it is more and more outstanding that contradiction shows.Therefore people are inquiring into the dyeing that exploitation is lower than boiling temperature always.
Facts have proved that for many years 80～90 ℃ of low temperature dyeings replace the boiling point not only energy savings that dyes, and to reducing the fibre damage of angle unit, the protection of special animal fibers such as especially tender cashmere, the rabbit hair, alpaca wool, baby lamb is significant.Several kinds of low temperature dyeing of wool methods commonly used at present; Formic acid method, glyoxal are arranged; Dioxygen water law, reductant additive process, organic amine method for pretreating, urea method, solvent method, pretreatment process and surfactant method etc.; Though certain effect is arranged, all has cost high, seriously polluted or wool fibre had drawbacks such as damage in various degree.
Enzyme improves hair quality technology and improves its colorability because its efficient pollution-free characteristic more and more receives people's attention, also is the technology that meets green textile standards fully.(wool spinning science and technology such as Fan Zenglu; Third phase calendar year 2001, the 20-23 page or leaf) when having pointed out that protease is used Protease Treatment to wool, the non-keratin matter of protease catalyzing hydrolysis fiber-intercellular binding; Thereby the rely passage of diffusion of dyestuff is increased, and dyeing rate significantly improves.The Protease Treatment wool causes wool intensity acutely to descend; Be protease to the hydrolysis of wool about this present dominant mechanism be the relation of a kind of " competing in the table "; Enzyme is not only in the wool surface action; Simultaneously also penetrate into the wool fibre internal action, the final result that causes is that wool fibre intensity reduces greatly.
Protein peptides has and the essentially identical part of wool fibre, and water-soluble peptide can penetrate into wool fibre inside, is cross-linked with each other, and improves strength of woollen fibre.People such as H king, Y Wu, JP Parry 0'Brien utilize peptide as hair benefit agents in patent CN 200680014955.6, have described peptide and have had the effect of hair conditioning increase hair intensity.
Summary of the invention
Technical problem to be solved by this invention provides a kind of hair and textile dyeing auxiliary agent thereof; This auxiliary agent can act on hair and fabric improves it to the dyestuff adhesive strength, and this method dyeing temperature is low, simple to operate, dyestuff strong adhesion, dyestuff utilization are efficient.Woolen fabric after this auxiliary agent dyeing is improved on colouring power and mechanical strength; Dye distribution is more even; More stable, the woolen dyeing assistant in this invention can directly act on all kinds of woolen fabrics; Save the chemical reagent pre-treatment in the processing procedure in the past, avoided environmental pollution.
The present invention provides a kind of woolen dyeing assistant, and component is protease, peptide, buffer solution, and the mass volume ratio of protease and buffer solution is 0.01-1g:100ml, and the mass volume ratio of peptide and buffer solution is 0.01-2g:100ml.
Said protease is trypsase, papain, Proteinase K, elastoser, pepsin, keratinase, cathepsin or subtilopeptidase A.
Said peptide is that molecular weight is one or more in the peptide of 500D-200kD.
Said peptide is protein or polypeptide.
Said buffer solution component is 50mmol/L Tris-HCl, pH6.0-8.0, Mg
2+1-3mmol/L, Ca
2+1-3mmol/L.
A kind of hair of the present invention and textile dyeing auxiliary agent thereof are applied to handle hair and fabric thereof; Concrete steps are: the protease, the peptide of mass volume ratio 0.01-2g:100ml and the dyestuff of 0.4-4%owf that in buffer solution, add mass volume ratio 0.01-1g:100ml; Owf is for being benchmark with the fabric weight; The percentage of the relative fabric of dyestuff, whenever add a kind of, abundant stirring and dissolving; Add hair or wool fabric by bath raio 1:10-50, bath raio is the mass ratio of fabric and dye liquor, places 30-60min for 25-70 ℃, places 10-60min for 70-95 ℃ then; Residual dye is removed in washing.
Beneficial effect
(1) the woolen dyeing assistant in this invention can directly act on all kinds of woolen fabrics, has saved the chemical reagent pre-treatment in the processing procedure in the past, has avoided environmental pollution, and can be applied to increases woolen dyeability in the wool fabric dyeing;
