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 textile printing and dyeing field, particularly a kind of hair and textile dyeing auxiliary agent thereof and its preparation method and application.
Background technology
Wool fibre is one of natural fabric that structure is the most complicated, and 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 the absorption of dyestuff and diffusion and is difficult to dye.In dyeing residual liquid, dye strength content is high, and sewage disposal is more difficult.In order to increase dyeing efficiency and dye utilization rate, dyeability ofwool fabric is the general high-temperature dyeing process that adopts at present, and dyeing time is also longer, and while causing dyeing, energy consumption is high.This technique does not meet 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 of exploitation lower than boiling temperature always.
Facts have proved for many years, 80～90 DEG C of low temperature dyeings replace boiling points dyeing not only to save the energy, and to reducing the fibre damage of angle unit, and the protection of the special animal fibers such as especially tender cashmere, the rabbit hair, alpaca wool, baby lamb is significant.Conventional several low temperature dyeing of wool methods at present, there are formic acid method, glyoxal, dioxygen water law, reductant additive process, organic amine method for pretreating, urea method, solvent method, pretreatment process and surfactant method etc., though have certain effect, all have cost high, seriously polluted or wool fibre is had to the drawbacks such as damage in various degree.
Enzyme improves hair quality technique and improves its colorability due to its efficient pollution-free characteristic, and be more and more subject to people and pay attention to, be also the technique that meets Green Textiles standard completely.(the wool spinning science and technology such as Fan Zenglu, third phase calendar year 2001,20-23 page) while having pointed out that proteases on wool is used Protease Treatment, the non-keratin matter-intercellular of protease catalyzing hydrolysis fiber binding, thereby make dyestuff rely diffusion passage increase, dyeing rate significantly improves.Protease Treatment wool causes wool intensity acutely to decline, the hydrolysis that is proteases on wool about this current dominant mechanism is the relation of a kind of " competing in table ", enzyme is not only in wool surfaces effect, also penetrate into wool fibre internal action, the final result causing is that wool fibre intensity reduces greatly simultaneously.
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.The 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 is to provide a kind of hair and textile dyeing auxiliary agent thereof and its preparation method and application, this auxiliary agent can act on hair and fabric improves it to dyestuff adhesive strength, and the method dyeing temperature is low, simple to operate, dyestuff strong adhesion, dyestuff utilization are efficient.Woolen fabric after this auxiliary agent dyeing is improved in colouring power and mechanical strength, dye distribution is more even, more stable, dyeability ofwool fabric auxiliary agent in this invention, can directly act on all kinds of woolen fabrics, save the chemical reagent pre-treatment in processing procedure in the past, avoided environmental pollution.
The invention provides a kind of dyeability ofwool fabric auxiliary agent, 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.
Described protease is trypsase, papain, Proteinase K, elastoser, pepsin, keratinase, cathepsin or subtilopeptidase A.
Described peptide is that molecular weight is one or more in the peptide of 500D-200kD.
Described peptide is protein or polypeptide.
Described buffer composition were 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 processes 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 taking fabric weight as benchmark, the percentage of the relative fabric of dyestuff, often add one, fully 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 DEG C, then places 10-60min for 70-95 DEG C; Residual dye is removed in washing.
Beneficial effect
(1) the dyeability ofwool fabric auxiliary agent in this invention, can directly act on all kinds of woolen fabrics, has saved the chemical reagent pre-treatment in processing procedure in the past, has avoided environmental pollution, can be applied in dyeability ofwool fabric, increases dyeability ofwool fabric performance;
