Abstract
The invention belongs to the field of printing and dyeing, and provides an assistant for printing and dyeing. The chemical structural formula of the assistant is disclosed in the specification. When in use, the assistant, which is 1.1-1.2 times by weight of the dye, can be added into dye liquor to obviously improve the dyeing and finishing quality and enhance the color fastness of the fabric, so that the color of the fabric is brighter.
Description
Technical field
The invention belongs to field of printing and dyeing, be specifically related to a kind of for improving the auxiliary agent of printing quality.
Background technology
Document CN1250829A discloses a kind of compound for printing and dyeing, and the chemical name of this compound is: 2-p-sulfonic acid base anilino--4-halo-6-β (α)-naphthalene oxygen (ammonia) base triazine, and its structural formula is as follows:
, R in formula
1: [SO
3h], [SO
3na]; R
2: F, Cl; R
3: α/β amido naphthalene, α/β naphthols.This compound can be as the cation dyes dyeing auxiliaries for animal protein fibre and the fabric thereof such as cation dyes dyeing and finishing wool/rabbit hair, has a dyeing and finishing quality good, lovely luster, COLOR FASTNESS advantages of higher.
Summary of the invention
The present invention finds the R in above-claimed cpd
2when group is Br, there is unexpected dyeing and finishing effect, can improve significantly COLOR FASTNESS, make color and luster more bright-coloured.
The purpose of this invention is to provide a kind of new 2-p-sulfonic acid base anilino-for printing and dyeing-4-halo-6-β (α)-naphthalene oxygen (ammonia) base triazine.
A kind of printing and dyeing used additives, the chemical structural formula of described auxiliary agent is as follows:
The application of above-mentioned auxiliary agent: during dyeing and finishing, 1.1～1.2 times by described auxiliary agent by dyestuff weight add in dye liquor.
Beneficial effect: compare with the 2-p-sulfonic acid base anilino-of fluoro-4-halo-6-β (α)-naphthalene oxygen (ammonia) base triazine, 2-p-sulfonic acid sodium anilino-of the present invention-4-bromo-6-α-naphthylamino triazine can significantly be improved dyeing and finishing quality, improve fabric color fastness, color and luster is more bright-coloured, and addition can reduce 50%.
The specific embodiment
Embodiment 1
But synthetic method list of references CN1250829A, specific as follows: as in reactor, with the 2.5kg cyanogen bromide, to be dissolved in 20 liters of ethanol, in temperature, it is 5 ℃, add the 1.8kg sodium sulfanilate under stirring, react 15 minutes, add again 0.6 liter of NaOH and phosphoric acid mixed liquor (by 8kg NaOH, 2kg phosphoric acid and 40kg water are made into), in temperature, be to continue reaction 70 minutes under 10 ℃, obtain intermediate product 2-p-sulfonic acid sodium anilino--4, 6-dibromo triazine, the alpha-naphthylamine that adds again 1.25kg, temperature rises to 15 ℃, react 3 hours, add 10 premium on currency, be cooled to-5 ℃, crystallization, obtain 2-p-sulfonic acid sodium anilino--4-bromo-6-α-naphthylamino triazine, its structural formula
.
2-p-sulfonic acid sodium anilino-of the present invention-4-bromo-6-α-naphthylamino triazine and cation dyes adapted, dyeing quality detects as follows:
Cation dyes (Basic Orange 0.0084 gram, grand red S-GLH 0.0066 gram of card magnetic, grand red BLH 0.0219 gram of card magnetic, three kinds of dyestuffs mix), the consumption of 2-p-sulfonic acid sodium anilino--4-bromo-6-α-naphthylamino triazine is 0.042 gram, be made into dye liquor with the 130ml demineralized water, pH=5～6, wool knitting yarn 3 grams; Adopt 2-p-sulfonic acid sodium anilino--4-fluoro-6-β-naphthylamino triazine to do contrast test, its consumption is 0.09 gram, and other is identical with 2-p-sulfonic acid sodium anilino--4-bromo-6-α-naphthylamino triazine test, and result of the test is as follows:
。
Claims (2)
1. a printing and dyeing used additives, is characterized in that, the chemical structural formula of described auxiliary agent is as follows:
2. the application of the described auxiliary agent of claim 1 is characterized in that: during dyeing and finishing, 1.1～1.2 times by described auxiliary agent by dyestuff weight add in dye liquor.
