Description

Reactive Brilliant Blue KN-R SR dye composite and preparation method thereof for printed fabrics

Technical field

The present invention relates to active dye technical field, particularly be Reactive Brilliant Blue KN-R SR dye composite that a kind of Salt And Alkali Tolerance good stability, enhancing are good and preparation method thereof.

Background technology

Blue active dye is in the market a lot, but with the gorgeous indigo plant of KN-R with the feature such as its bright-coloured coloured light, sun-proof weather (look) fastness is good by the very widely used a kind of anthraquinone type reactive dyestuffs of dyeing, but it is due to the feature of self molecular structure, intermolecular easy association, especially when adding alkali fixation, sulfuric ester ethene sulfuryl becomes ethene sulfuryl, and more easily hydrolysis is separated out, and is easy to cause look pattern point on fabric, reduce its dye uptake, and produced more dyeing waste-water.Along with China's rapid economic development, due to domestic energy shortage, environmental pollution is serious, more and more higher to the requirement of product transformation upgrading, to energy-saving, environment-friendly active dye demand is increasing.We are exactly on the basis of Reactive Brilliant Blue KN-R, utilize the technology of dyestuff compound synergic, add appropriate auxiliary agent, improved salt tolerant alkalescence and the enhancing of the gorgeous indigo plant of KN-R under normal dyeing, Reactive Brilliant Blue KN-R SR of the present invention has fabulous level-dyeing property and pile-on properties, can be both for level dyeing performance is had higher requirements as: cheese dyeing, garment dyeing, can be used for again the energy saving and environment friendly dyeing of relatively praising highly now: cold-rolling heap staining.The present invention has more amazing improving performance than colleague's product SUMITOMO CHEMICAL SumifixBrillian t BlueR Specal.

Summary of the invention

The object of the invention is to overcome the deficiency of coventional type Reactive Brilliant Blue KN-R, a kind of have splendid salt tolerant alkalescence and the reactive dye compositions of enhancing are provided.

Reactive Brilliant Blue KN-R SR of the present invention is comprised of following component by weight percentage:

Adopt general method evenly to mix after above-mentioned each component, or in process of production according to the ratio of each component and solid content, carry out after solution wet mixing is spelled evenly that spraying is dry just can obtain these reactive dyestuffs.

In Reactive Brilliant Blue KN-R SR of the present invention, the structural formula of each component is as follows:

Described additive is one or more the mixture in sodium sulphite, thiourea peroxide, vat powder, S-WAT, sodium lignosulfonate, dispersing agent NNO, dispersing agent MF, urea.

Described emulsifying agent is one or more the mixture in emulsifier os-15, emulsifying agent A-20, emulsifying agent C-125, trolamine.

The chemical structural formula of preferred additive compound is as follows:

The blue structural similitude of above-mentioned additive and C.I Reactive Blue 19 100 and para-isomeride thereof, composite by a certain percentage with homemade alkyl naphthalene sulfonic acid formaldehyde condensation products after, have Salt And Alkali Tolerance stabilization and the castering action of obvious enhancing dyestuff.

Reactive blue KN-RSR of the present invention is a kind of uniform mixture based under compound synergic principle, utilize supermolecular theory, improved the salt tolerant alkalescence poor defect of Reactive Brilliant Blue KN-R under normal dyeing condition, strengthened the improving performance of dyestuff simultaneously, there is fabulous level-dyeing property and pile-on properties, can be both for level dyeing performance is had higher requirements as: cheese dyeing, garment dyeing, can be used for again the energy saving and environment friendly dyeing of relatively praising highly now: cold-rolling heap staining.

Embodiment

Embodiment 1:

Take 100g Reactive Brilliant Blue KN-R (intensity 125%), 10g contraposition blue (intensity 120%),

Naphthalene sulfonic acidformaldehyde condensation product (self-control) 30g, 1-2 component 1g in addition of C 1--C12, Sodium hexametaphosphate 99 0.5g, emulsifying agent 1g, dust-proofing agent 0.5g, makes dye composite of the present invention after sufficiently mixing: Reactive Brilliant Blue KN-R SR100%.

Embodiment 2:

Take 100g Reactive Brilliant Blue KN-R (intensity 125%), 8g contraposition blue (intensity 120%),

Naphthalene sulfonic acidformaldehyde condensation product (self-control) 20g, 1-2 component 1g in addition of C 1--C12, Sodium hexametaphosphate 99 0.5g, emulsifying agent 1g, dust-proofing agent 0.5g, makes dye composite of the present invention after sufficiently mixing: Reactive Brilliant Blue KN-R SR120%.

Reactive Brilliant Blue KN-R SR of the present invention and conventional Reactive Brilliant Blue KN-R, SUMITOMO CHEMICAL Sumifix B rilliant BlueR Specal are carried out to the test of salt tolerant alkalescence relatively.

Concrete Salt And Alkali Tolerance stability test method is as follows:

1. cold rolling heap salt tolerant alkalescence method of testing (C method)

In 100mL deionized water, add 10g commercialization dyestuff, be warming up to (60 ± 2) ℃, insulation 10min makes it to dissolve.Be cooled to (25 ± 2) ℃, sampling.With spotting method, on Xinhua's 4 filter paper, confirm its complete molten after.Under stirring, add 3g Sodium sulfate anhydrous.min(99), add 3mL massfraction 3O NaOH solution.Maintain stirring, every 5min sampling, with spotting method, observe it and separate out situation.Till having on filter paper to sample and obviously separating out, calculate the alkaline-resisting time.

2. conventional salt tolerant alkalescence testing method (W method)

In 100mI deionized water, add 2g commercialization dyestuff, at 6O ℃, be incubated 20min and make it abundant dissolving.Be cooled to (25 ± 2) ℃, under stirring, add 100mL saline solution (containing 20g/LNa2C03 and 50g/L Na2S04 in saline solution).At 25 ℃, every 5min sampling, with spotting method, observe its dissolving situation.Till having obvious haloing to sample on filter paper, calculate the alkaline-resisting time.

Reactive Brilliant Blue KN-R SR of the present invention and common Reactive Brilliant Blue KN-R, and SUMITOMO CHEMICAL Sumifix Br illiant BlueR Specal(is called for short: the salt tolerant alkalescence test result blue RSP in Sumitomo) is as following table 1:

Sequence number	Dyestuff title	The C method Salt And Alkali Tolerance time	The W method Salt And Alkali Tolerance time
				1	KN-RSR100% of the present invention	180 minutes	>=30 minutes
2	KN-RSR120% of the present invention	150 minutes	>=25 minutes
				3	Conventional KN-R100%	1 minute	≤ 5 minutes
4	The blue RSP100% of SUMITOMO CHEMICAL	180 minutes	>=55 minutes

Reactive Brilliant Blue KN-R SR of the present invention and common Reactive Brilliant Blue KN-R, and SUMITOMO CHEMICAL Sumifix Br illiant BlueR Specal(is called for short: the enhancing test result blue RSP in Sumitomo) is as following table 2:

From the test result of table 1, table 2, can find out:

1. conventional Reactive Brilliant Blue KN-R, does not add any auxiliary agent.Its Salt And Alkali Tolerance Sodium sulfate anhydrous.min(99) stable testing time is less than 1 minute, adds alkali and separates out immediately, and enhancing is extreme difference also, and red soup phenomenon appears in dye liquor.

2. external colleague's product SUMITOMO CHEMICAL Sumifix Brilliant Blue R Specal Salt And Alkali Tolerance stability is fine, but its depth is not ideal enough, promotes rate variance.

3. the existing good Salt And Alkali Tolerance stability of Reactive Brilliant Blue KN-R SR of the present invention has again good improving performance simultaneously, can guarantee that dyestuff can not condense separate out and complete smoothly various dyeing courses.
