Abstract
The invention relates to a novel method used to increase the solubility of mordant black P2B dye, wherein during mixing mordant black P2B dye, composition is calculated according to the following percentage by mass: 100 portions of mordant black P2B, 25 to 45 portions of polyhydroxy aliphatic aldehyde and 0.5 to 2 portions of non-ionic surface active agent. Because dyeing auxiliary agent, anhydrous sodium sulphate is changed to polyhydroxy fatty aldehyde during mixing commercialized mordant black P2B, the solubility of dye is increased from 20g/l to more than 30g/l at 90 DEG C. The novel method increases dye uptake, reduces dye consumption, and has better economic benefits.
Description
Technical field
The present invention relates to a kind of commercial dye constituent, relate to the Mordant Black dyestuff specifically.
Background technology
Medium black P 2 B is a kind of dyeing behavior excellent dye kind, be mainly used in the dyeing of fibers such as wool, silk, polyamide fibre, dye level is good, level-dyeing property is good except that having, the dye uptake advantages of higher, the characteristics that its dyeing waste water colourity is low more are subjected to the current favor of paying attention to the environmentalist both at home and abroad.
In recent years, the producer of domestic production medium black P 2 B is less, and demestic user such as Erdos etc. are all by from the import of external producer such as Japanese hillside plot, and the product of domestic only manufacturer has a long way to go on the printing and dyeing application performance.Especially continue to use materials such as traditional dyeing auxiliaries Sodium sulfate anhydrous.min(99) substantially on dyestuff piece together to mix, thereby the dyestuff solvability is relatively poor, is generally 20g/L (90 ℃ time), influence Color, dyestuff consumes height, influences economic benefit.
Summary of the invention
According to the existing low defective of medium black P 2 B solubleness, the invention provides a kind of easy to use, method that can improve solubility of medium black P 2 B dyestuff.
The concrete technical measures that solve the problems of the technologies described above are:
Medium black P 2 B (C.I.Mordant Black 7)
CAS：3618-60-8
Structural formula:
Molecular formula: C
16H
10ClN
2NaO
6S
Relative molecular weight: 416.77 (by international relative atomic mass in 1997)
Usually medium black P 2 B carries out commercialization and pieces together to mix and be: medium black P 2 B and Sodium sulfate anhydrous.min(99) mixing and stirring be the commodity medium black P 2 B dyestuff, but its solubleness of this commercial dye only can reach 20g/L (90 ℃ time).
The present invention changes additive into polyhydroxy fatty aldehyde by Sodium sulfate anhydrous.min(99) in commercialization of dyes, add nonionogenic tenside simultaneously, and dyestuff is pieced together mixing method and pieced together mixing method with conventional dyestuff.
Used polyhydroxy fatty aldehyde general formula is C
nH
2n-m+1(OH)
mCHO, wherein n 4～12, m 2～10.
According to raw material sources and price, suitable polyhydroxy fatty aldehyde is: 1,2, and 3-trihydroxy-butyraldehyde, 1,2,3,4-tetrahydroxy valeral, 2,3,4,6,7-penta hydroxy group capraldehyde, 3,4,5,6,7,8-hexahydroxy-lauric aldehyde, 1,2,3,4,5,6-hexahydroxy-octanal, 1,2,3,4-tetrahydroxy hexanal, 1,2,3,4,5-penta hydroxy group hexanal, 2,4,6,8-tetrahydroxy capraldehyde, 1,3,5,7,9-penta hydroxy group aldehyde C-9,1,2,3,4-tetrahydroxy enanthaldehyde, 1,2,3,4,5,6-hexahydroxy-enanthaldehyde, 2,3,4,5, the 6-penta hydroxy group undecyl aldehyde etc.
Polyhydroxy fatty aldehyde consumption, in mass parts (down together), 100 parts of medium black P 2 Bs add 25～45 parts of polyhydroxy fatty aldehyde.
Nonionogenic tenside is the commercial goods tensio-active agent, main component is: branched secondary alcohol Soxylat A 25-7 or direct-connected secondary alcohol Soxylat A 25-7 etc., the nonionogenic tenside that is suitable for has TMN-3, TMN-6, TMN-10, NK-500,15-S-9,15-S-5,15-S-40, dispersion agent JH-ND2100.
The nonionogenic tenside consumption is 0.5～2 part.
What traditional method added in the assembly of dyestuff mixes is Sodium sulfate anhydrous.min(99), belongs to inorganic salt, because inorganic salt have salting out, adding organism does not then have salting out, and can gain in strength, and hydroxyl what do not have influence to colorant dissolubility.Polyhydroxy fatty aldehyde consumption is to select according to the intensity of former dyestuff, and intensity heals high consumption more greatly, and solubleness is bigger, and maxima solubility reaches 35g/L (at 90 ℃).Add the dispersion level-dyeing property that nonionogenic tenside can improve dyestuff.
The invention has the beneficial effects as follows: owing to when piece together mixing the commercialization medium black P 2 B, change the dyeing auxiliary Sodium sulfate anhydrous.min(99) into polyhydroxy fatty aldehyde, the solubleness that makes dyestuff is brought up to more than the 30g/L (90 ℃ time) by 20g/L.Improve dye uptake, save dyestuff consumption, favorable economic benefit is arranged.
