Abstract
The invention discloses a fabric leveling agent for an acid dye. The fabric leveling agent is prepared from the following materials by mass percent: 6 to 12 percent of styryl phenol polyoxyethylene ether ammonium sulfate, 3 to 8 percent of octadecylamine polyoxyethylene ether sodium laureth sulfate, 6 to 10 percent of peregal O, 2 to 6 percent of polyoxyethylene ether glycerol oleate, 5 to 10 percent of polyoxyethylene hydrogenated lanolin and the balance of deionized water. The fabric leveling agent is suitable for leveling acid and neutral dyes, good in leveling performance and stability, easy to dissolve at the normal temperature and convenient to use; and a leveling agent system is good in hard water resistant stability, good in affinity to dyes and wool fibers, favorable for dispersing and retarding the dye and capable of improving the utilization rate of the dye.
Description
Technical field
The present invention relates to the auxiliary agent field of textile process, be specifically related to the fabric levelling agent of a kind of acid stain.
Background technology
Often produce the phenomenon that dyeing is uneven when all kinds of dyestuffs are for stock-dye, produce color flower.Solve to dye when uneven most common method is Colour Difference and add levelling agent.Levelling agent is and can delay dyeing kinetics in dyeing course or strengthen the textile auxiliary moving dye and obtain level dyeing effect, and in stock-dye process, different dyes needs different levelling agents with dyeing.
In acid stain molecule, the acidic-group containing sulfonic group and carboxyl etc. forms the form of acylate, owing to they are relatively big to the affinity of fiber, not easily contaminates even, it is therefore desirable to add levelling agent and process.When wool fiber is dyeed by acid stain, existence due to the appearance cortex of fibrous hydrophobic and the scale layer of densification, and the diversity of wool fiber itself causes that the affinity of dyestuff be there are differences by fiber, easily cause the aberration problem of uneven dyeing and Rhizoma Imperatae tippy tea；And acid stain is when dyeing to chinlon, owing to dye molecule can become salt binding or be combined with the form of hydrogen bond with the amino of nylon fibre end, therefore chinlon is had stronger affinity by the dye molecule in dye bath, causes that acid stain even dyeing effect on chinlon is poor；Lyocell fiber after cation-modified can use acid dyeing, but acid stain even dyeing effect is had higher requirement by the dyeing of its blending product.
Summary of the invention
Not enough for prior art, the invention provides and a kind of acid stain is had fine dispersion effect ease up the fabric levelling agent of dye effect.
This invention address that the technical scheme that above-mentioned technical problem adopts is: the fabric levelling agent of a kind of acid stain, be made up of following raw material: styrene phenol polyoxyethylene ether ammonium sulfate, octadecylamine polyethenoxy ether sodium sulfovinate, paregal O, polyoxyethylene ether glycerol oils acid esters, polyethylene glycol hydrogenated lanoline and deionized water；
The mass percent of described raw material is: styrene phenol polyoxyethylene ether ammonium sulfate 6～12%, octadecylamine polyethenoxy ether sodium sulfovinate 3～8%, paregal O 6～10%, polyoxyethylene ether glycerol oils acid esters 2～6%, polyethylene glycol hydrogenated lanoline 5～10%, surplus are deionized water.
Described styrene phenol polyoxyethylene ether ammonium sulfate has excellent dyestuff dispersibility, initial stage slow metachromia, and dyestuff synchronizes the features such as colourability；It is without solvent and carrier component, it is possible to maintains dye bath and dyes in acid condition, is prevented effectively from sensitive dye hydrolysis and the cloth cover chromatic light deviation that causes.
Having nonionic, anion, 3 kinds of functional groups of cation in described octadecylamine polyethenoxy ether sodium sulfovinate molecule, can produce complexation with dyestuff, even dyeing effect is good.
Described paregal O is excellent nonionic surfactant, and resistance to hard water is strong, and foaming power is low, except reaching level dyeing purpose, it is also possible to simultaneously work as certain washing effect, makes the color and luster after dye more bright-coloured.
The preparation method of described polyoxyethylene ether glycerol oils acid esters: first ethylized by glycerol oxygen, then oleic acid esterification obtains described polyoxyethylene ether glycerol oils acid esters again, and described polyoxyethylene ether glycerol oils acid esters can promote the stability in hard water energy of levelling agent system.
Described polyethylene glycol hydrogenated lanoline in the presence of a catalyst, after lanoline Pressurized-heated catalytic hydrogenation, can carry out catalyzed polycondensation with oxirane and prepare；The present invention finds through experiment, and levelling agent system adds described polyethylene glycol hydrogenated lanoline can improve even dyeing effect and color fastness, and makes the complex of dyestuff and levelling agent have enough dissolubility, to be unlikely cohesion too much.
Compared with prior art, the advantage that the present invention possesses: the fabric levelling agent of a kind of acid stain provided by the invention is relatively suitable for acid and neutral dye level dyeing, shows good level-dyeing property and stability, readily soluble under room temperature, easy to use；The resistance to hard water of levelling agent system has good stability, dyestuff and wool fibre is all had good affinity, is beneficial to the gentle dye of dispersion of dyestuff, is conducive to improving the utilization rate of dyestuff.
