Active orange dye composition

Abstract

The invention provides an active orange dye composition which mainly comprises one or a plurality of components A the structures of which are shown as a formula (I) and one or a plurality of components B the structures of which are shown as a formula (II). Based on the components A and the components B, the mass percent of the components A is 1 to 99 percent, and the mass percent of the components B is 1 to 99 percent; the active orange dye composition has high colour yield, high fixation rate and high enhancement property; and moreover, when the active orange dye composition is applied to cellulose fibre or a material containing the cellulose fibre for dyeing and printing, the active orange dye composition has good dyeing stability and bright colour, and various kinds of fastness, such as water washing resistance, friction resistance, perspiration resistance and colour fastness of chlorine water resistance, are excellent.

Description

(1) Technical field [0001] The invention relates to a reactive orange dye composition, in particular to a reactive orange dye composition suitable for dyeing and printing cellulose fibers or materials containing cellulose fibers. (2) Background technology [0002] The improvement of the color fixation rate and wet rubbing fastness of fabrics dyed with reactive dyes has always been the focus and difficulty in printing and dyeing production. Soaping removes, but there is intermolecular force between unfixed dyes and cotton fibers, and some remain on the fabric after soaping. At the same time, the covalent bonds between some reactive dyes and cotton fibers are affected by external conditions and are easy to Bond breaking hydrolysis occurs, which causes the color fastness of dyed fabrics to deteriorate, especially the color fastness to washing, friction, perspiration and chlorine water cannot meet the production requirements. Such as published patents CN1274734A and KR200200715...
