Abstract

The invention relates to complex active brown SCN pigment, prepared with pigment of active navy blue, active yellow and active red. The weight proportion of said three pigments is10- 30: 55- 70: 15- 30. The printing can be other colors such as coffee or brown by moderating the pigment adding amount, the dissolving degree is 160g/l. The lifting power is apparently increased, and the level-dyeing property and color stability are good. The fastness to light is grade 4, color fastness to soaping is grage 4, rub proofness is grade 4, and color fastness to perspiration is 4 for 20 g/l pad dyeing cloth.

Description

A kind of built reactive palm SCN dyestuff and manufacture method thereof

Technical field

The invention belongs to technical field of dye, refer in particular to a kind of built reactive palm SCN dyestuff, the manufacture method of this built reactive palm SCN dyestuff is provided simultaneously.

Background technology

The active reddish brown K-B of tradition ₃The production process of R is: alkaline coupling is carried out in the diazonium salt and the J acid constituents of anthranilic acid and hydrochloric acid and Sodium Nitrite reaction, coupling finishes to get the formulated chromaking agent of filter cake and chromium sulphate, Whitfield's ointment, NaOH and ammoniacal liquor of saltouing and carries out the reaction of high temperature chromaking, and chromaking is reacted end and cyanuric chloride and the condenses of (beta-sulfuric ester ethyl sulfonyl) aniline is carried out the secondary condensation reaction and forms.The shortcoming of this technology is: complex process, the solubleness of dyestuff has only 30 grams per liters, produces large amount of sewage.Dyestuff shows as in application process that lifting force is not enough, and level-dyeing property is bad, can not dye dark color.The pad dyeing cloth of its 10g/l, 4 grades of light fastness, soaping fastness 3-4 level, dry fastness 3-4 level, 4 grades of fastness to perspirations.

Chinese patent CN200510041206.X discloses a kind of composite brown active dye, by reactive black, reactive red, reactive yellow is composite constitutes, wherein reactive yellow is that sulfonation is carried out acid coupling to (beta-sulfuric ester ethyl sulfonyl) aniline and hydrochloric acid, Sodium Nitrite at diazonium salt and the 2.4-diamino benzene sulfonic acid sodium that 0-10 ℃ of reaction generates, product behind the acid coupling carries out alkaline coupling with the diazonium salt that (beta-sulfuric ester ethyl sulfonyl) aniline and hydrochloric acid, Sodium Nitrite reaction are generated at 5-10 ℃ again, the pH value of alkaline coupling is controlled to be 5-7, and coupling finishes directly dried the forming of spray.This product can improve the staining fastness of dyeing cloth, but its cost is higher in the brown product of activity uses.

Summary of the invention

Built reactive palm SCN be at present dyeing to high strength, the high-dissolvability of reactive dyestuffs, can dye dark color and cleaner production and the composite kind of three colors researched and developed, have lovely luster, solubleness height, advantages such as substantivity is low, compatibleness good, favorable reproducibility, good level-dyeing property, enhancing rate height, degree of fixation height, easily washing property is good, colour fastness is good, especially it is good to account for colour fastness, meeting under the situation of printing quality, greatly reduce cost.This patent adopts the cleaner production patent, and the needs that the combination dye compounded technology successfully solves product dye dark color, and lifting force is good, the characteristics that less energy-consumption and fastness are good.

A kind of built reactive palm SCN dyestuff carries out multiple assembly by reactive navy blue, reactive yellow and three kinds of dyestuffs of reactive red and forms, and the weight proportion that it is characterized in that three kinds of materials is 10-30: 55-70: 15-30, wherein:

The reactive navy blue structural formula is as follows:

The reactive red structural formula is as follows:

Reactive yellow is: (beta-sulfuric ester ethyl sulfonyl) aniline and hydrochloric acid, Sodium Nitrite are reacted the diazonium salt and 2 that generates, 4-diamino benzene sulfonic acid sodium carries out behind the acid coupling and the diazonium salt of (beta-sulfuric ester ethyl sulfonyl) aniline and hydrochloric acid and Sodium Nitrite is carried out alkaline coupling under 5-10 ℃, PH=6-8, directly sprays dried forming.

The manufacture method of built reactive palm SCN dyestuff is characterized in that reactive navy blue, reactive yellow and reactive red solution are mixed by proportioning, and spray is done again.Production technique adopts the technology that cleans, and production process does not have sewage and produces, and has only equipment washing to produce a little sewage, and contamination level reduces more than 99%;

The built reactive palm SCN dyestuff multiple coloured light such as coffee-like, brown of can the adjustment by consumption printing and dyeing, solubleness reaches 160 grams per liters, lifting force obviously improves, good level-dyeing property, and it is fine to account for colour fastness, can dye dark color, the pad dyeing cloth of its 20g/l, 4 grades of light fastness, 4 grades of soaping fastnesses, 4 grades of dry fastnesses, 4～5 grades of fastness to perspirations.Show the superiority of the reddish brown better printing quality of specific activity.The temperature printing and dyeing had alleviated the energy consumption of dyeing and the utilization ratio of dyestuff during this product application showed as, and the purity height of dyestuff has reduced the water consumption of printing and dyeing enterprise simultaneously.

Embodiment

Embodiment 1, and a kind of built reactive palm SCN dyestuff carries out multiple assembly by 10 parts of reactive navy blues, 70 parts of reactive yellows and 20 parts of reactive reds by weight and mixes, and sprays dried forming again, wherein:
