Abstract

The invention discloses a red active dye composition, which consists of active red dyes A, B and C and an assistant. In the invention, through the selection and reasonable mixing and combination of the three conventional red active dyes, an exceptional technical effect is achieved; and with the synergetic effect of the three dyes, the red active dye composition has higher lifting performance and wet fastness and more outstanding wash fastness, sun fastness, wear fastness, sweat fastness and chlorine water fastness.

Description

A kind of red reactive dye composition

Technical field

The present invention relates to the textile printing and dyeing field, particularly relate to a kind of red reactive dye composition.

Background technology

One of reactive dyestuffs ecological dyeing free-revving engine is for energy-saving and emission-reduction and improves security of products.Along with some traditional dyestuffs, for example directly, reduction and thioxine dyes use rapidly and reduce, reactive dyestuffs are used rapidly and are enlarged, and the kind of many dark colors and strong color also extensively adopts reactive dyeing.Because reactive dye color fixing mechanism and characteristics, use reactive dyeing and stamp commonly used in the past, when particularly printing and dyeing dark heavy colour kind, painted degree of fixation, enhancing and colour fastness are not high, not only bring dyeing efficient and cost problem, more outstanding is to produce serious ecological problem.For addressing the above problem, the dyestuff industry has been released a series of dyestuffs, and what have is the compound of one-component, and is more then be the composite of multi-component dyes.

C.I. reactive red 223# and similar structures dyestuff thereof, this class dyestuff is the reactive dyestuffs of well-known amide-containing, its formula is:

It is red that this class dyestuff color and luster is gold-tinted, has the water-fast preferably colour fastness of washing, colour fastness to rubbing and sun-resistant fastness.But its enhancing rate, degree of fixation and colour fastness to perspiration and the photochromic fastness of sweat proof etc. remain further to be improved.

The JP4033965 of SUMITOMO CHEMICAL house journal introduced C.I. reactive red 223# and C.I. REACTIVE Red 195 # piece together by a certain percentage mixed, so as to improving dyeing behavior and the fastness of C.I. reactive red 223#.But for the stamp of medium-to-high grade fabric, particularly need the imitative wax seal flower of rich and gaudy color and luster, still there are the nonconforming problems of wet colour fastness such as relatively poor, washable, the anti-chlorine of lifting force, rub resistance and perspiration resistance in above-mentioned prior art.

Summary of the invention

At the deficiencies in the prior art, one of purpose of the present invention is to provide a kind of red reactive dye composition, and this dyestuff has high wet colour fastnesses such as washable, anti-chlorine, rub resistance and perspiration resistance, to solve the problem that prior art exists.

For achieving the above object, the technical solution adopted in the present invention is:

A kind of red reactive dye composition, it is to form to have the dyestuff A of structural formula (I), to add the dyestuff B of (II) that has structural formula and any one or multiple dyestuff C and the auxiliary agent with general formula (III);

Structural formula (I)

Structural formula (II)

General formula (III)

In the general formula (III), Y is vinyl or formula C ₂H ₄Group shown in the Q, L by or not by 1 or 2 non-conterminous Sauerstoffatoms or 1 or 2 imino-C at interval ₂-C ₆-alkylidene group, perhaps L is a cyclohexylidene, Hal is a fluorine or chlorine, R ¹Be hydrogen or hydroxyl alkylsulfonyl methyl, R ³Be carboxyl or hydroxyl alkylsulfonyl;

Wherein by weight percentage, A is 50-56%, and B is 22-26%, and C is 12-14%, and auxiliary agent is 4-16%; Described each component sum is 100%; Described auxiliary agent is one of following or wherein two or more mixture: Dispersant MF, dispersing agent NNO, sulfonated lignin, pH buffer reagent, dust-proofing agent, thickening material, stablizer, mould inhibitor.

Red reactive dye composition of the present invention can prepare by conventional methods.

Dye composition of the present invention is applicable to the printing and dyeing of the printing and dyeing, particularly cotton fabric of fabrics such as cotton, fiber crops, silk, leather, wool.When adopting the above-mentioned filamentary material of active dye printing of the present invention, can abide by the known reactive dyes dyeing process and carry out, as reactive dyestuffs in exhaustion staining, pad dyeing staining and printing method commonly used.

Beneficial effect of the present invention is mainly reflected in:

By selection and rational proportion combination to existing three kinds of red reactive dyes, obtained unexpected technique effect, the collaborative mutually of three kinds of dyestuffs makes compared to existing homochromy dyestuff, red reactive dye composition of the present invention demonstrates excellent enhancing and moisture resistance properties, and washable, sun-resistant, rub resistance, perspiration resistance and the colour fastness of anti-the chlorine water are outstanding.

Embodiment

Among the following embodiment, for sake of convenience, the middle substituting group of general formula (III) that only provides dyestuff C is: Y is a vinyl, and L is a cyclohexylidene, and Hal is a fluorine, R ¹Hydroxyl alkylsulfonyl methyl, R ³Be a kind of situation of carboxyl, but those skilled in the art should be clear and definite, this does not represent and limits the scope of the invention.

The composition of the red reactive dye composition of embodiment 1-7 is as shown in table 1.
