CN1927948A - Sublimation fastness improved dispersion red dyes mixture - Google Patents

Abstract

The disperse red dye mixture with raised sublimation fastness consists of dye in the chemical general expression as shown in 5-95 wt%, and C.I. disperse red 343, C.I. disperse red 92 or C.I. disperse red 146 in 5-95 wt%. The disperse red dye mixture has sublimation fastness raised to Level 3, and may be compounded with disperse blue 2BLN and disperse yellow in the same sublimation fastness to form various kinds of marketable dyes with balanced sublimation fastness. It may be also used directly in dyeing.

Description

A kind of sublimation fastness raising type disperse red dye mixture

Technical field

The present invention relates to a kind of dispersed dye that are applicable to polyster fibre or dyeing fabric, particularly a kind of sublimation fastness raising type disperse red dye mixture.This dispersive red dye can be used as one of basic three-primary colours, DISPERSE YELLOW identical with other sublimation fastness and EX-SF DISPERSE BLUE EX-SF 300 constitute one group of three-primary colours dyestuff and are used for colorant match, when middle light polyster fibre and dyeing fabric, solved because of the inconsistent problem that causes serious changes of shade of each dyestuff composition distillation.In addition, this dispersive red dye also can be directly used in dyeing.

Background technology

Dispersed dye are to be dispersion state the starting stage in dyeing course to carry out a painted class nonionic dye, wherein, sublimation fastness is one of important indicator of disperse dyeing quality, and it is meant the degree of the distillation phenomenon that DYED FABRICS takes place in heat setting type.Sublimation fastness is scalded variable color after handling, is faded and calico staining degree through xeothermic pressure with grey classification scale evaluation fabric, is divided into 5 grades, and 1 grade the poorest, and 5 grades best.Normal generally speaking coloration of textile materials sublimation fastness requires to reach 3～4 grades and just can meet and wear requirement.The inventor is in the practice of secular fabric printing, and employed three-primary colours dye sublimation fastness is obviously inconsistent when noticing in the past polyster fibre and dyeing fabric.For example (DISPERSE BLUE 2BLN is a trade(brand)name with DISPERSE BLUE 2BLN, international Colour Index code name is the C.I. Disperse Blue-56), DISPERSE YELLOW E-RG, Disperse Red 3B be one group of three-primary colours dyestuff, with the visible DISPERSE BLUE 2BLN of GB 180 degree test in 30 seconds sublimation fastness is 3 grades, and DISPERSE YELLOW E-RG is 2 grades, and Disperse Red 3B is 2.5 grades.So when the arrangement typing of middle light color processing dyeing back,, cause dyeing quality to descend, directly influence quality product because of the dye sublimation performance difference causes serious changes of shade.

Summary of the invention

The invention provides a kind of sublimation fastness raising type disperse red dye mixture, its objective is will solution and after DISPERSE YELLOW and EX-SF DISPERSE BLUE EX-SF 300 constitute one group of three-primary colours dyestuff colorant match, when being used for polyster fibre and dyeing fabric, because of the inconsistent problem that causes serious changes of shade of each dyestuff composition distillation.

For achieving the above object, the technical solution used in the present invention is: a kind of sublimation fastness raising type disperse red dye mixture, and this dye mixture contains the dyestuff of following two kinds of structures:

One is for meeting the dyestuff of chemical general formula (I), and content is calculated as 5～95% of Disperse Red with dyestuff dry product weight:

R in the formula ¹Be hydrogen, alkyl, alkoxyl group, hydroxyl or halogen, or sulfoamido unsubstituted or that replace;

It two is C.I. Disperse Red 343 or C.I. Disperse Red 92 or C.I. Red-1 200 46, and content is calculated as 5～95% of Disperse Red with dyestuff dry product weight.

Related content in the technique scheme is explained as follows:

1, in the above-mentioned chemical general formula (IV), described R ^IFor unsubstituted sulfoamido specifically is SO ₂NH ₂The sulfoamido that replaces specifically is the SO that is connecting substituted radical ₂NH-or SO ₂N＜.

The present invention is according to the needs of dyeing and finishing technology arrangement workshop section, studied a kind of sublimation fastness and be 3 grades disperse red dye mixture, this dyestuff is a benchmark with the sublimation fastness of DISPERSE BLUE 2BLN, be used for colorant match and dyeing as one of three-primary colours dyestuff, when middle light polyster fibre and dyeing fabric, solved because of the inconsistent problem that causes serious changes of shade of each dyestuff composition distillation.Adopt the Disperse Red of the present invention and the DISPERSE YELLOW of DISPERSE BLUE 2BLN and identical sublimation fastness to form basic three-primary colours dyestuff and mix the dyestuff of risking various tones commonly used on the market, has the sublimation fastness balance too, with DISPERSE BLUE 2BLN, DISPERSE YELLOW E-RG, Disperse Red 3B were that one group of three-primary colours dyestuff is compared in the past, the look that can obviously improve the typing front and back becomes, and improves yield rate.

Embodiment
