Abstract
A production method of an alkali-resistant high temperature-resistant low-foaming penetrating agent for dyeing relates to the technical field of production of low-foaming penetrating agents for pure cotton or polyester cotton fabric dyeing. The method of the invention comprises the following steps: firstly performing an esterification reaction of isooctyl alcohol and P2O5 to obtain an esterified ester; performing neutralization reactions of the esterified ester with a KOH aqueous solution and isopropanol in order, adjusting the solid content of the product with water, and adjusting the pH value to 7-8. The low-foaming penetrating agent prepared by the method of the invention is applicable to dyeing of pure cotton or polyester cotton fabrics, can resist a high temperature of 210 DEG C, resist a NaOH concentration of 300 g/L in dye liquor during dyeing and finishing, prevent dye liquor from layering, and improve dyeing uniformity and color fastness.
Description
Technical field
The present invention relates to the textile printing and dyeing technology, especially for the production technical field of the low bubble bleeding agent of usefulness that cotton textiles or polyester-cotton fabric are dyeed.
Background technology
Penetrating agent JFC (AEO) belongs to non-ionic surface active agent.Can make the penetrant that textile dyeing is bathed and arrangement is bathed, play osmosis, also be to have a fixing hydrophilic and oleophilic group, align at the surface energy of solution, and the material that surface tension is significantly descended.But because existing bleeding agent can only tolerate 150 ℃ temperature, containing NaOH concentration in the dye liquor that when dyeing and finishing, can only tolerate is 80g/L, this non-refractory, and also not alkaline-resisting characteristic is prone to make the dyeing liquor layering in dyeing course, influences Color.
Summary of the invention
The present invention seeks to propose a kind of dyeing liquor layering of avoiding, improve the production method of the alkaline-resisting high temperature resistant low bubble dyeing of Color with bleeding agent.
The present invention is earlier with isooctanol and P
2O
5Under 70 ± 2 ℃ condition, carry out esterification, obtain carboxylate; Again carboxylate is successively carried out neutralization reaction with the KOH aqueous solution, isopropyl alcohol, regulate the solid content of product then with water, regulate pH value to 7～8 with the KOH aqueous solution again.
The low bubble bleeding agent of processing with the inventive method is used for the dyeing of cotton textiles or polyester-cotton blend lining, has to tolerate 210 ℃ high temperature, and the concentration of NaOH is 300g/L in the tolerant dye liquor when dyeing and finishing, can make dye liquor not stratified, improves the uniformity and the COLOR FASTNESS of dyeing.
Isooctanol according to the invention, P
2O
5, the mass ratio that feeds intake of KOH and isopropyl alcohol is 216～280 ︰, 5～100 ︰, 20～120 ︰ 50～100 in the KOH aqueous solution.
Esterification according to the invention is: isooctanol is joined in the reaction pot of cleaning, dry zone reflux, add powdery P lentamente
2O
5, control reaction temperature is no more than 50 ℃, then, reaction mass is warming up to 70 ± 2 ℃, and insulation reaction to reaction finishes, and reduces to normal temperature, and discharging obtains esterification products.
Said neutralization reaction is: earlier the preparation mass percent is 40% the KOH aqueous solution in neutralization chamber, is no more than in reaction temperature under 60 ℃ the condition, slowly adds the esterification products stirring reaction; After reaction finishes; Add isopropyl alcohol after reaction mass is cooled to 30 ℃, stir, regulate the pH value of product at last with the KOH aqueous solution; After being cooled to normal temperature, filtration, blowing.
For the Different products solid content is provided, the present invention also can regulate the solid content of product with water before the pH value of regulating product.
The specific embodiment
One, produce low bubble bleeding agent:
1, esterification:
216～280kg isooctanol is joined cleaning, drying, takes back in the reaction pot of stream device, agitating device and chuck, in chuck, feed cold water, the temperature of control reaction mass is no more than 50 ℃, under agitation slowly evenly adds 50～100kg powdery P
2O
5, after adding,, make the interior material of reaction pot be warming up to 70 ± 2 ℃ through in chuck, feeding hot water or steam, be incubated 2 hours, then cooling, discharging.
2, neutralization reaction:
In neutralization chamber, prepare 50～300kg mass percent and be 40% the KOH aqueous solution.
Under agitation, slowly add esterification products to neutralization chamber, the control temperature is no more than 60 ℃, is cooled to 30 ℃ after fully stirring, and adds 50～100kg isopropyl alcohol, stirs, and last water is regulated solid content, regulates pH value to 7～8 of product again with the KOH aqueous solution.
After the cooling, refilter, obtain and filter material, be product.
Two, properties of product:
Product of the present invention and water, KOH, dyestuff etc. are mixed the formation dye liquor, and the concentration of NaOH is under the high alkalinity condition of 300g/L in dye liquor, in drying cylinder performance temperature is under 210 ℃ the condition, cotton textiles or polyester-mixed cotton cloth to be dyeed.In the whole dyeing course, do not occur obvious lamination in the dye vat, the lining color of dying is even.
