Description
Technical field
The present invention relates to the colouring method of a kind of dyeing, particularly a kind of cellulose base fiber fabric.
Background technology
Cellulose fibre is the textile fabric of output maximum in the world, and wherein, cotton fiber is as natural fibreCellulose fiber, owing to thering is good water imbibition, hygroscopicity, easy dyeing, soft, intensityAppropriateness, the advantage such as comfortable and easy to wear, is widely used in life. Cellulose fibre is with negative in dye bathElectric charge, and the dyestuff that great majority dye cotton fiber is anionic property, due to electrostatic repulsion, dyestuff upperDye and be suppressed, for reducing electrostatic repulsion, in dye bath, need to add a large amount of neutral electrolytes to improve dyestuffDye-uptake is according to the difference of dye structure, color, also different by salt amount. Nonetheless, dyestuff is upperDye rate and degree of fixation still lower, especially reactive dye. So not only increase production cost, andA large amount of discharges containing hydrolised dye and electrolytical dyeing waste-water, have brought great pollution to environment." modification and Dyeing Technology of Cellulose Fabric ", Song Huijun etc., dyeing and finishing technique 2007 (29)Although disclose, cellulose fibre is carried out to modification, only rest on the laboratory research stage. For reachingFixation object, the hydroxyl on cellulose need, in ionization under strong alkaline condition, so dye the later stage, dyeIn liquid, must add a large amount of soda ash, if publication number is the disclosed technical scheme of CN105019269A.Be a difficult problem for puzzlement industry always to the processing of inorganic salts and alkali, not only cannot have reclaimed in a large number but also hard degradationInorganic salts enter rivers and lakes, severe contamination water quality, because salt has very high permeance property, makesSoil property salinization of soil around, becomes a difficult problem very thorny in environmental protection.
Summary of the invention
The object of the invention is, in order to overcome the deficiencies in the prior art, provides a kind of cellulose base fiber fabricColouring method, described colouring method adopts cation modifier to change cellulose base fiber fabricProperty, change the surface property of fabric, greatly improve dye-uptake and the degree of fixation of all kinds of anionic dyes,In dyeing course, do not use inorganic salts, reduce dyeing waste water discharge capacity, used middle warm type to live simultaneouslyProperty dyestuff, even dyeing, color fastness are higher.
The present invention can be achieved through the following technical solutions:
The colouring method that the invention discloses a kind of cellulose base fiber fabric, comprises the following steps:
(1) pretreatment: cellulose base fiber fabric is floated to bottom reason;
(2) cellulose base fiber fabric modification: the cellulose base fiber fabric that step (1) is floated at the end soaksBubble is in the aqueous solution of cation modifier;
(3) washing: the cellulose base fiber fabric after step (2) is soaked is washed fully;
(4) dyeing: the cellulose base fiber fabric after washing is sent in dye vat and dyeed;
(5) softening: the cellulose base fiber fabric after dyeing is softened to processing;
(6) post processing: the cellulose base fiber fabric after softening is cleaned fully and dried.
In described step (1), float the mixing for pure water, hydrogen peroxide, soda ash and anti wrinkling agent in end containerSolution, described hydrogen peroxide, soda ash and anti wrinkling agent quality percentage composition be respectively 6～12%, 4～9%,4～5％；
In described step (2), cation modifier is epoxy compounds, the salinization of cyanuro quaternary ammoniumCompound, cationic acrylamide base co-polymer, azacyclo-cationic compound, polyamide epichlorohydrin resin,One in natural cation modifier, polycation based compound and polyamine based compound, cationModification can be introduced cationic group or compound in fabric, changes the surface property of fabric, largeLarge dye-uptake and the degree of fixation that improves all kinds of anionic dyes do not reduce even and uses in dyeing courseInorganic salts, reduce dyeing waste water discharge capacity; Quaternary ammonium cation or protonated amino dye reactive dyeLook plays the short effect of dying; Cyanuro quarternary ammonium salt compound reactivity is high, can make fiber effectively connectUpper cation, its heat endurance is better than epoxy compounds, and double activated multi-quaternary ammonium salt modifier can improveThe adhesion of itself and fiber, greatly reduces reagent dosage; Cationic acrylamide base co-polymer is a kind of reactionProperty polymer, can with cellulose fibre generation necleophilic reaction, polymer is anchored on fiber, dyeingIn process, between fiber and polymer, polymer and dyestuff and dyestuff and fiber, can react,Form crosslinkedly at fibrous inside, can effectively improve the dye-uptake of dyestuff, reduce the discharge of dyestuff waste liquid,Can realize salt-free dyeing; The mass ratio of described cation modifier and cellulose base fiber fabric is1～1.5：50；
The dyestuff adopting in described step (4) staining procedure is middle Resist Reactive Dyes, described inThe mass ratio of Resist Reactive Dyes and cellulose base fiber fabric is 8～15:100; Described middle warm type activityDyestuff is reactive dark blue M-2GE, reactive turquoise blue BGFN, reactive brilliant yellow 6GLN, reactive brilliant buleKN-R, active black KN-B; Described dyeing temperature is 60～80 DEG C, keeps 30～50min, then withThe speed of 1～2 DEG C/min is warming up to 90～95 DEG C, insulation 30～60min;
In described step (4) staining procedure, also added color-fixing agent, described color-fixing agent is color-fixing agentSR-FRN, it can improve dyestuff color moisture resistant fastness on fabric, on fabric can with dyeWashing, the perspiration fastness expecting to form insoluble colored substance and improved color, also can improve its Exposure to Sunlight jailDegree.
The colouring method of a kind of cellulose base fiber fabric of the present invention, has following beneficial effect:
The first, the present invention dyes to cellulose base fiber fabric, adopts cation modifier to fabricCarry out modification, in fabric, introduce cationic group or compound, change the surface property of fabric,Greatly improve dye-uptake and the degree of fixation of all kinds of anionic dyes, and reduce even in dyeing courseDo not use inorganic salts, reduce dyeing waste water discharge capacity.
The second, in dyeing course, used Resist Reactive Dyes, even dyeing, color fastness are higher,There is high rinsing fastness and light fastness than general reactive dye.
Three, in staining procedure, also add color-fixing agent, can improve dyestuff color on fabric resistance toWet colour fastness, on fabric, can form insoluble colored substance with dyestuff and improved color washing,Perspiration fastness, also can improve its light fastness, and the method technique is simple, with low cost.
