Description

A kind of NEW TYPE OF COMPOSITE reactive black dye and application
Technical field
The present invention relates to composite dye, and in particular to a kind of NEW TYPE OF COMPOSITE reactive black dye and application.
Background technology
In the market the reactive black dye by obtained by dark blue component, orange component and red component are compound is primarily present solid Color rate is low, and color fastness is not excellent enough, and dyeing course dyestuff facile hydrolysiss, utilization rate are low, while the problems such as dyestuff pitch black degree is inadequate, gives Printing and dyeing enterprise brings stern challenge.
Chinese invention patent ZL98106332.2 discloses a kind of dyestuff of reactive black WNN series, and the popularization time is longer, occupies The suitable market share.Orange component and chinlon have stronger affinity in dyestuff, when bright and beautiful cotton blend is dyeed, on the chinlon on Color rate is higher, reduces the dye exhausting rate of cotton component, shows particularly evident in bright and beautiful cotton one-bath dyeing so that dyestuff is utilized Rate declines.
Reactive dye are hydrolyzed rapidly under alkaline hot conditionss, and hydrolised dye has at high temperature good upper during nylon dyeing Color rate, but cannot anchor on chinlon, by painting on fabric again in post processing major part hydrolised dye elution process, such as This is repeated staining, causes staining and causes dyeing product unqualified to the alternate striped that is left white of bright and beautiful cotton, although part printing and dyeing mill By using releasing soaping agent eluting part hydrolised dye, this measure can undoubtedly increase production cost, it is impossible to fundamentally solve this Class problem.
With the increasingly raising of living standard, requirement of the people to textile product also more and more higher, so as to textile dyeing Constantly lifting is both needed on properties, makes great efforts to improve the degree of fixation of reactive dye and the dyefastness of textile, be finally reached Dyeing waste-water is reduced, consumer demand is met.
The content of the invention
Present invention aims to the deficiencies in the prior art, there is provided a kind of NEW TYPE OF COMPOSITE reactive black dye and application, The degree of fixation of reactive dye and the dyefastness of textile are not only increased, and has efficiently controlled dyeing production cost.
Technical scheme provided by the present invention is：
A kind of NEW TYPE OF COMPOSITE reactive black dye, component B of component A containing such as formula I, such as formula II and such as formula (III), component C of formula IV or formula (V)；
Wherein, Y is CH=CH2、CH2CH2OH、C2H4OSO3H、C2H4OSO3Na or C2H4Cl；R1~R3And R1'~R3' mutually Independently it is expressed as hydrogen, hydroxyl, methoxyl group or methyl.
In above-mentioned technical proposal, cellulose fibre active group-C is introduced in component A (orange component)2H4OSO3Na、- C2H4OSO3H or-CH=CH2, the increase of active group in dye structure makes dyestuff be combined with cellulose fibre more firmly, dyestuff Degree of fixation and the color fastness of dyed fabric be obviously improved, dyestuff staining on bright and beautiful cotton is remarkably decreased.Secondly, by from excellent Different commercialization auxiliary agent, improves the alkali resistance in dyeing course, reduces dyestuff hydrolysis, effective control dyeing production cost；Choosing With with component B good component C of (dark blue component) compatibility (red component), it is compound after reactive black dye have it is excellent pitch-black Degree.
Preferably, being made up of following component in terms of weight fraction：10~35% as formula I component A, 45~80% such as Component B of formula II, component C of 5~25% such as formula III, formula IV or formula (V), balance of auxiliary agent and/or filler.
Preferably, Y is C in the formula I2H4OSO3H, structural formula is as follows：
Preferably, R in the formula II1-R3And R1′-R3' hydrogen or methoxyl group are expressed as independently of each other.
Preferably, component B is selected from following structural formula：
Or
Preferably, the dispersant is in Dispersant MF, dispersing agent NNO, dispersing agent CNF and dispersant Reax85A One or more.More preferably Dispersant MF.Wherein dispersant is primarily to raising dyestuff is resistance in dyeing course Alkalescence, slows down the hydrolysis rate of dyestuff, improves dye utilization rate.
Preferably, the filler is Matrii Sulfas Exsiccatus.
The present invention also provide a kind of dyeing of NEW TYPE OF COMPOSITE reactive black dye described above on cotton, fiber crops, viscose fiber or Application in stamp.
Compared with the existing technology, beneficial effects of the present invention are embodied in：
(1) active group-CH is introduced in component A (orange component)2CH2OSO3H, because of the increase of dye activity group, makes dye Dye uptake of the material on fabric is improved, while also improving the degree of fixation of dyestuff.
(2) using the dyed fabric of the composite active black dye in the present invention, its color fastness is also obviously improved, especially exists Chinlon staining in washing fastness is remarkably decreased, and application performance is significantly improved.The improvement of orange component structure causes dyestuff Utilization rate is greatly increased, and effectively reduces high chroma, the discharge of high COD dyeing waste-waters.
(3) by from excellent commercialization auxiliary agent and filler, improving the alkali resistance of the dyestuff in dyeing course, reduce Dyestuff is hydrolyzed, and improves dye utilization rate, effective control printing and dyeing cost；
(4) increase-CH in orange component A2CH2OSO3H groups so that colorant dissolubility improves to some extent, component A And reaction similar temperament direct with component C and dark blue component B, the K/S of the product dyed fabric after compounding is of a relatively high, so as to crow Blackness is significantly improved, and can more meet the special pitch black demand of client's dye.
