Abstract

The invention discloses an active red dye composition which comprises a component A and a component B. The component A is selected from at least one of compounds shown in a formula (I), and the component B is selected from at least one of compounds shown in a formula (II). The dye composition is bright in color, high in solubility, good in alkali resistance, excellent in washing resistance and color fastness to light, and suitable for printing and dyeing cellulosic fibers or cellulosic fiber-containing materials, especially for one-bath dyeing of blended fabrics such as brocade / cotton, viscose / cotton and the like.

Description

[0001] (1) Technical field [0002] The invention relates to a reactive red dye composition and a dye product, in particular to a reactive red dye composition and a dye product suitable for one-bath dyeing of nylon cotton. [0003] (2) Background technology [0004] Nylon belongs to polyamide fiber, which has high resilience, fatigue resistance, and good moisture absorption performance; while cotton belongs to cellulose fiber, which has the advantages of soft hand feeling, good air permeability and moisture absorption, and comfortable wearing, but it is easy to wrinkle. After weaving brocade and cotton, the fabric can not only have the advantages of brocade and cotton fibers, but also overcome their respective shortcomings, showing a strong body and smooth feel. Affected by the structure of polyamide and cellulose itself and the performance and process of the dyes used in the dyeing process, the traditional nylon / cotton fabric dyeing method uses two-bath dyeing methods such as ...
