Problems solved by technology

Although the above studies have certain effects in solving the same color of brocade, there are still problems that cannot be solved in the selection of dyes, such as: 1. In the dyeing of wool brocade blends, if dyeing with acid dyes is easy to occur the problem of poor fastness
2. Dyeing with neutral dyes can effectively improve the fastness of dyed fabrics, but there are corresponding shortcomings of poor level dyeing and insufficient vividness

Abstract

The invention relates to the field of dyestuff and particularly relates to a red complex dye used for wool / chinlon blend dyeing. The red complex dye comprises the following components in parts by weight: 50 to 90 parts of a compound A, 3 to 30 parts of a compound B and 0.1 to 20 parts of a compound C, wherein the molecular structural formula of the compound A is shown in the formula (I), the molecular structural formula of the compound B is shown in the formula (II), and the molecular structural formula of the compound C is shown in the formula (III). The red complex dye provided by the invention adopts a bath method for dyeing to a piece of wool / chinlon blend fabric, and the obtained wool / chinlon blend fabric is excellent in color yield consistency, has fresh and lovely luster and is excellent in color fastness. The wool / chinlon blend fabric obtained by adopting the red complex dye provided by the invention for dyeing can meet market requirements on color brightness, fastness, dyeing synchronism, compatibility and the like, has excellent properties, and has a wide application scope.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a red composite dye used for wool brocade blended dyeing. Background technique [0002] Wool / nylon blended fabric combines the advantages of wool and nylon fiber, and has good wearing performance and unique style. In addition to being widely used as woven carpet materials, it can also be used as high-end clothing fabrics such as fashion and dresses, and has a broad market prospect. The one-step dyeing process of wool / brocade blended fabrics is simple, saves energy and reduces consumption, and has little damage to wool and other fibers, which can greatly improve production efficiency and reduce costs. [0003] Due to the different physical and chemical properties of wool and brocade fibers, the dyeing properties of dyes on fibers are different. At present, in wool brocade blended dyeing applications, more related auxiliaries are used to adjust the color yield of dyes on different fibers. Fo...
