Problems solved by technology

Superfine fiber is a new type of synthetic fiber, which has the advantages of soft hand feeling, breathable and moisture absorption, and comfortable to wear. Because of its fine monofilament fiber, large specific surface area of ​​fiber, fast coloring speed, it is not easy to dye evenly and deeply. In actual dyeing , and several kinds of dyes are commonly used to solve the problem, but the color coordination of monomer dyes is a difficult problem

Abstract

The invention discloses a dispersed bright-red dye composition, which mainly consists of red dye components A mixed according to structural formulas (I-a) and (I-b) and red dye components B shown by a structural formula (II). The dispersed bright-red dye composition solves the problem about coloring harmony on monomer dye during practical dyeing and has excellent color fastness and dyeing depth.

Description

a technical field [0001] The invention relates to a scarlet mixture and a preparation method thereof, in particular to a disperse scarlet dye mixture suitable for use in medium-dark dyeing of superfine fibers, and belongs to the technical field of dye preparation. Two background technology [0002] Disperse dyes are a kind of non-ionic dyes that are in a dispersed state in the initial stage of the dyeing process. The particle size is about 1um, and they are evenly dispersed in water with the help of dispersants. It is the most widely used synthetic dye in the printing and dyeing process of textiles and clothing. It has the advantages of bright color, excellent fastness, and a wide variety of colors. It is used for dyeing and printing of various natural and synthetic fibers. Superfine fiber is a new type of synthetic fiber, which has the advantages of soft hand feeling, breathable and moisture absorption, and comfortable to wear. Because of its fine monofilament fiber, large ...
