Abstract

The invention discloses an acid dye. In the invention, the dye and salt thereof are highly compatible with the known acid dyes. The dye disclosed by the invention is also suitable for being used together with other dyes of the chromophore, and the ratio of the dye existing in the combined tone dyeing or printing composition depends on the tone to be obtained. By adopting the technical scheme disclosed by the invention, because natural additives are added, the wet processing fastness of the compounded acid dye is improved, the fiber hand feeling can not be changed, and the suction ratio of the dye is also greatly improved.

Description

A kind of matching stain

Technical field

The present invention relates to the new dye technical field, relate in particular to the method for preparing ingredients thereof of acid dye mixture.

Background technology

Traditional matching stain is meant the water-soluble dye that contains acidic-group, and the contained acidic-group overwhelming majority is present on the dye molecule with the sulfonate sodium form, and it is to exist with the carboxylic acid sodium salt form that indivedual kinds are only arranged.Early stage this type dyestuff all is dyeing under acidic conditions, so the common name matching stain.The uniform dyeing property of matching stain on wool, silk, polyamide fibre is relatively good, but wet colour fastness is not a unanimity.Generally, the level-dyeing property that dyes polyamide fibre is poor, and wet colour fastness is then better; The level-dyeing property that dyes silk is relatively good, but wet colour fastness is inferior to woolen dyed fastness.Aborning; Strongly-acid is bathed painted matching stain and mainly is used for dyeing wool; And the matching stain of slightly acidic bath and neutral-bath dyeing; Except dyeing wool, also can be used for the dyeing of silk and polyamide fibre because matching stain is very low to the substantivity of cellulosic fibre, so generally dye cellulosic fibre without matching stain.It is complete that matching stain has chromatogram; Characteristics bright in colour; Be mainly used in the dyeing and the stamp of protein fibres such as wool, real silk and tynex, also can be used for the painted of leather, paper, makeup and ink, minority also is used to make food dye and pigment lake.

Summary of the invention

The technical problem that the present invention will solve is to matching stain more existing problems in dyeing in the prior art, and a kind of novel acid dye mixture is provided, and it can solve defective of the prior art to a certain extent.

For solving the problems of the technologies described above; The invention provides following technical scheme: a kind of matching stain; Comprise matching stain; It is characterized in that: also comprise auxiliary agent and stablizer, said auxiliary agent is one or more the mixture in anionic starch, amphoteric starch, Sumstar 190, denaturated starch by acid, white dextrin, maltodextrin or cyclodextrine, modified inulin, polysaccharide mixture, the enzymatic hydrolysis starch.

As a kind of optimal way of dyestuff according to the invention, wherein 10: 5 of the weight percent of matching stain, auxiliary agent, stablizer～10: 1～3.

As a kind of optimal way of dyestuff according to the invention, wherein 10: 10: 1 of the weight percent of matching stain, auxiliary agent, stablizer.

As a kind of optimal way of dyestuff according to the invention, said matching stain is C.I. turmeric yellow 40, C.I. turmeric yellow 44, C.I. turmeric yellow 48, C.I. turmeric yellow 49, C.I. turmeric yellow 54, C.I. turmeric yellow 60, C.I. turmeric yellow 66, C.I. turmeric yellow 74, C.I. turmeric yellow 86, C.I. turmeric yellow 92, C.I. turmeric yellow 98, C.I. turmeric yellow 102, C.I. turmeric yellow 154, C.I. turmeric yellow 202; C.I.
