Dye composition used in the present invention can be easily by well known to those skilled in the art Mode synthesizes, it is possible to use commercial goods.
The disperse yellow dye composition that the present invention provides, generally with its aqueous solution after commercialization Form is applied to the printing and dyeing of textile material, is preferred for dyeing polyester fibers, such as, uses Conventional dip method, pad-dyeing method dye.
This dye composite use conventional method prepare: as with commercial dye by said ratio Each component is mixed and forms;Or will be each with pressing said ratio after the former dyestuff conversion of synthesis After component mixing, form through sand milling, spray drying.The formulation of its dyestuff can be liquid, powdery or Granular.Therefore, above-mentioned dye composite contains by weight: 20~60% synthesis former Dyestuff and 40~the diffusant of 80%.
Below in conjunction with specific embodiment, the present invention will be further described, but the guarantor of the present invention The scope of protecting is not limited to this.
Commercial dye and chemical constitution that the embodiment of the present invention one uses are as follows:
Dyestuff 1
Dyestuff 2
Dyestuff 3
According to data shown in table one, after each dye component and diffusant are mixed, both To corresponding dye composite.For contaminating dacron fabric, it is dispersion yellow.
Table one dyestuff composition table
Above-mentioned dye combinations is all applicable to HTHP and pad-dry-cure dyeing, and its dyeing is for common Colouring method, is not described at this.
Each embodiment dye composite contaminates to obtain the fastness of pure polyester textile, with C.I. disperse yellow 23 (Y23) are for doing one and compare with reference to listing table 2 in.
The main fastness of table 2 and feature of environmental protection comparison sheet
Taking yellow 23 finished product 1.0 grams respectively, embodiment 1 finished product material 0.5 gram is scattered in 500 grams In cold water, mix with 32mL water after taking 10mL after being sufficiently stirred for, adjust with acetic acid Joint pH=4.0, puts into 2 grams of polyster fibres and dyes, with the heating rate of 3 DEG C/min Rise to 130 DEG C, be cooled to 80 DEG C after insulation 30min, clean sampling, it is thus achieved that yellow dyeing and weaving Thing, without reduction cleaning, carries out coloured light with Datacolor 400 and compares, and it the results are shown in Table 3。
Table 3 coloured light comparative result
Wherein DeFor total color difference, DlFor lightness, DcFor saturated colour difference, DhFor form and aspect Difference, DaFor red green difference, DbPoor for champac.
By upper Colorimetric results, it can be seen that more yellow 23 coloured light of coloured light of example 1 dyestuff are yellow, bright; Bright in colour.
In sum, the dye composite dye polyester textile of the present invention is yellow, has excellent Dyeing washing fastness;Comparing with C.1. disperse yellow 23, washing fastness all increases significantly.
When preparing dyes polyester fiber with the disperse dye composition of the present invention, look can be obtained Light is bright-coloured, good dispersion, water-fastness, the yellow fabric of environment-friendly type.
The foregoing is only the preferred embodiment of the application, be not limited to the application, For a person skilled in the art, the application can have various modifications and variations.All Within spirit herein and principle, any modification, equivalent substitution and improvement etc. made, Within should be included in the protection domain of the application.
