preparation example Construction

[0055] The preparation method of the yellow reactive dye composition of the present invention comprises mixing the above-mentioned dye I: dye II according to a prescribed weight ratio. Various conventional methods can be used for mixing, such as mechanical mixing methods. When mixed, dye I and dye II may be present in powder form, or in granular form, or in aqueous solution.

[0056] Dye I can be purchased from the market as a known yellow reactive dye (trade name: reactive yellow SHE, Jiangsu Shenxin Dyestuff Chemical Co., Ltd.), and can also be prepared according to known methods. For example, its preparation method has been specifically described in US 5,484,899 (1996) and CN 1569969 (2005) (incorporated herein as a reference), including:

[0057] a) Make 2-naphthylamine-di- or trisulfonic acid diazonium salt and an amino group -CONR a R b or -COR a (R a and R b The protected m-phenylenediamine or its derivatives having the above-mentioned meanings) are coupled under ...

Abstract

A yellow active dye composite containing yellow active dye Iand yellow active dyeIIin proportion of 90-10:10-90 and its use are disclosed. In the general formula, M is selected from H or alkali metal; R is selected from -CONRaRb or -CORa, Ra and Rb are selected from H or C1-4 alkyl separately; X is halogen atom; n is 2 or 3; Z is -CH2CH2OSO3M or -CH=CH2. It has bright color, permeability, fastness, compatibility and dyeing degree.

Description

technical field [0001] The invention relates to a yellow reactive dye composition and its application. Background technique [0002] Reactive dyes have the characteristics of bright color, excellent application performance, convenient use and strong applicability. In recent years, due to environmental and ecological constraints, users have higher and higher requirements for the fastness of dyed fabrics and various application properties of dyes. [0003] The development of yellow reactive dyes has always been a hot spot in the dye industry. Various yellow reactive dyes with different structures show different application properties. [0004] The representative kind of the yellow reactive dye widely used in the current market is C.I.Reactive Yellow145 (produced by Sumitomo Corporation of Japan), and the domestic brand name is reactive yellow M-3RE. Its structural formula is: [0005] [0006] There are certain defects in this dye, that is, its molar extinction coeffici...
