Abstract
The present invention belongs to the field of light chemical engineering, and particularly to a polyester fiber dyeing auxiliary agent. The present invention provides a special auxiliary agent for polyester disperse dye basic dyeing, wherein the special auxiliary agent can be adapted to basic dye bath and dying, can eliminate the reduction cleaning step, and even can be matched with the one-bath process of desizing, refining and dyeing, the final dyeing fabric has characteristics of good level dyeing property and soft hand feeling, and the color fastness reducing due to carrier dyeing is avoided.
Description
Technical field
The invention belongs to Light Chemical Engineering field, especially relate to a kind of dyeing used additives of polyster fibre.
Background technology
Polyester fabric dyed with disperse dyes fiber is continued to use the dyeing of weak acidic medium always, and pH general control is 4.5～6, and this is mainly from the viewpoint of the stability of dyestuff and fiber.But the pretreatment procedure such as fine of opening of the destarch of dacron, lax, alkali decrement and dacron ultrafine fiber fabric all carries out under alkali condition, before dyeing, must, through fully washing and acid neutralization, remove the residual alkali on fabric.And after having dyeed, also need in alkaline medium, carry out reduction cleaning, the post processing such as soap.Along with the development of dyeing and technology, people are more and more higher to pursuit quick, energy-saving dyeing technique, and since the eighties in last century, people study dacron basic dyeing, remain so far the focus of a research.
In DISPERSE DYES basic dyeing, seldom use NaOH as alkaline agent, this is because NaOH is a kind of highly basic, in the aqueous solution, can ionize completely, and OH-is a kind of strong nucleopilic reagent, and easily the low atom of electronegativity in attack dyestuff, is destroyed dye structure.Normal some inorganic weak bases of using are as alkaline agent, as Na
2cO
3, Na
3pO
4, NaBO
34H
2o etc., as patent CN103243581A, patent CN1208097A.Now research finds that the strong basicity resisting of part DISPERSE DYES is better, can meet to take the alkali condition dyeing that NaOH is medium, realizes the processing technology of the destarch of polyster fibre and the one-step method that dyes.Some cushioning liquid play certain protective effect to dyestuff in terylene basic dyeing, as NaOH-buffered with amino acid liquid, NaOH-borax buffer solution etc.But in this alkaline dye liquor, contain the impurity such as oligomer, dyestuff, dispersant, fine bits, as easy as rolling off a log generation uneven dyeing phenomenon, even dyestuff can condense.And the heat-resisting alkaline stability of some auxiliary agent is poor, also unstable in this basic dyeing environment, easily there is sex change.The research > > of < < dacron ultrafine fiber basic dyeing levelling agent (textile technology progress, the 2nd phase in 2013) also to propose to take o-phenyl phenol be main containing carrier alkalescence levelling agent to a literary composition, but this levelling agent can make the dyeability of terylene change, staining color fastness decreased, colorfastness to rubbing also can decline.
Summary of the invention
The object of the present invention is to provide a kind of special assistant that is applicable to terylene DISPERSE DYES basic dyeing, concrete technical scheme is:
Terylene basic dyeing one auxiliary agent, its each component calculates according to percentage by weight and is:
Disodium ethylene diamine tetraacetate (EDTA-2Na) 20-30%
Trihydroxy methyl aminomethane 12-16%
AMPD 4-10%
DMG 0-10%
Sodium dihydrogen phosphate 0-16%
Tween 80 2-8%
NNO 20-30%
Water 0-42%.
The preparation method of above-mentioned terylene basic dyeing one auxiliary agent is conventional stirring, by weight percentage, each component is mixed, and stirs.
The present invention also provides the application of a kind of above-mentioned terylene basic dyeing one auxiliary agent in dyeing, is specially:
Terylene basic dyeing one auxiliary agent adds after terylene pre-treatment washing, without regulating pH value.During use, can or successively put into dye bath together with alkali resistance disperse dye, concrete dyeing recipe is: bath raio is the mass ratio of 1:15～50(fabric and dye liquor), alkali resistance disperse dye is with respect to the 0.1-10% of fabric (being o.w.f.) weight, and the concentration of basic dyeing one auxiliary agent in dye liquor is 2-5 gL
-1.
Beneficial effect of the present invention is:
Some commercially available alkali dyeing assistants can make the initial pH of dye bath remain on 8.5～10.5 at present, terylene basic dyeing one provided by the invention agent can make dye bath keep comparatively stable alkaline pH: by dye liquor pH maintain between 9.2-9.4 among a small circle in, when 130 ℃ of dyeing temperatures, still can guarantee the stable of dye liquor pH value, to obtain good Color and feel;
Terylene basic dyeing one provided by the invention agent can adapt to alkaline dye bath dyeing, omit reduction cleaning operation, even can coordinate the technique of destarch, refining and one-pass bath method for dyeing, final DYED FABRICS good level-dyeing property, soft, avoid the reduction of the COLOR FASTNESS that carrier dyeing causes simultaneously;
Terylene basic dyeing one of the present invention agent can make polyster fibre dye under alkali condition, effectively reduce the impact of oligomer, coloured light zero deflection after dyeing, dyefastness increases, the feel of polyster fibre is more soft simultaneously, in plant produced, can reduce the water-washing process before dyeing, reduce costs.
