Description
Technical field
The present invention relates to a kind of technical field of dye, and in particular to a kind of disperse dyes.
Background technology
Into after 21 century, the competition in world textile market is more and more fierce, and the economy in Southeast Asia has turned into low cost, height
The synonym of growth, and the textile industry business in Europe, U.S. etc. also accelerates to be shifted to Asia.Swash to adapt to piece market
The situation of strong competition, the production cost for making textile is constantly reduced, product quality is improved constantly, carrying capacity of environment constantly mitigates,
As the common target of textile enterprise.
With the development of synthetic fibers, polyamide fibre, terylene occur in succession, especially terylene, due to high, the fiber with permutation degree
Space is few, the characteristic such as hydrophobicity is strong, to make swelling of fiber in the case where having carrier or high temperature, thermosol, dyestuff could enter fiber and on
Dye.Disperse dyes are the water-soluble relatively low nonionic dyes of a class, and solubility is very low in water, and particle is very thin, in dye liquor
In dispersion, the dyeing of acetate fiber, referred to as cellulose acetate dye, its dyeing for being mainly used in terylene to be used for earliest.
With the fast-developing and raising of the people to textile demand of polyester Fresh fats in recent years, correspondingly, to dyestuff sheet
Dyeability that body has, environmental-protecting performance it is also proposed requirement higher, it is desirable to which dyestuff has lifting force high and every dyeing jail
Degree.But most study is the good disperse dyes of alkali resistance at this stage, but these dyestuffs are difficult to be provided simultaneously with excellent dye
Color performance and fastness ability.
The content of the invention
The invention provides a kind of disperse dyes, the disperse dyes have preferable dyefastness.
The technical scheme is that：A kind of disperse dyes, shown in the component A, structural formula (II) as shown in structural formula (I)
Component B, component C, the component D shown in structural formula (IV) shown in structural formula (III) and auxiliary agent composition：
As mass fraction, the mass fraction of the component A is 2~15%, the mass fraction of the component B for 10~
The mass fraction of 35%, the component C is 5~10%, and the mass fraction of the component D is 8~25%, and remaining is auxiliary agent；
The R is-NHCOCH3Or-OCH3。
Each component in the present invention can use existing commercial goods, also can be according to side well-known to those skilled in the art
Method synthesizes.
The present invention is by rational allocation so that every dyefastness and dye uptake of disperse dyes are higher, show each group
The certain synergy an of/presence.
Preferably, as mass fraction, the mass fraction of the component A is 4~15%, and the mass fraction of component B is
The mass fraction of 15~30%, component C is 5~10%, and the mass fraction of component D is 12~20%, and remaining is auxiliary agent.
Preferably, as mass fraction, the mass fraction of the component A is 4~12%, and the mass fraction of component B is
The mass fraction of 15~25%, component C is 5~8%, and the mass fraction of component D is 14~20%, and remaining is auxiliary agent.
Preferably, as mass fraction, the mass fraction of the component A is 8%, the mass fraction of component B is 25%,
The mass fraction of component C is 8%, and the mass fraction of component D is 18%, and remaining is auxiliary agent.
Preferably, the component A as shown in formula (I -1) and formula (I -2) compound with mass ratio be 1:3 mix.
Auxiliary agent in the present invention can select auxiliary agent conventional in the art (including dispersant, wetting agent, etc.), used as excellent
Choosing, the auxiliary agent be naphthalene sulfonic acid-formaldehyde condensation product, lignosulfonates and benzyl sulfonate and formaldehyde condensation product in one kind or
It is two or more.
Preferably, the auxiliary agent is the mixture of lignosulfonates and benzyl sulfonate and formaldehyde condensation product, the wood
Mahogany sulfonate is 1~3 with the mass ratio of benzyl sulfonate and formaldehyde condensation product:2~5.
Preferably, the mass fraction of the auxiliary agent is no more than 55%.
Disperse dyes of the invention can be obtained by preparation method conventional in the industry, such as by component A~D by pre-
If proportioning mixing after, carried out with reducing mechanisms such as sand mill or grinders in the presence of auxiliary agent, water or other wetting agents micro-
Particlized, that is, obtain the disperse dyes；Can also be first by component A~D respectively in the presence of auxiliary agent, water or other wetting agents
Corpusculed is carried out with reducing mechanisms such as sand mill or grinders, is then mixed according to default proportioning, that is, obtain described
Disperse dyes.
Compared with prior art, beneficial effects of the present invention are：
Component C of the invention introduces methyl on the ortho position of coupling component amino, and methyl is electron-donating group, and this is allowed for
Component C has certain hyperchromic effect, and component C is a kind of disperse dyes, although component C has certain hyperchromic effect, but
The present invention is by rational allocation so that every dyefastness and dye uptake of disperse dyes are higher, show to be deposited between each component
In certain synergy.
Specific embodiment
The present invention is described in further detail with reference to specific embodiment.
