Abstract

The invention discloses a preparation method of a dispersing red dye. The preparation method comprises S1, mixing a C. I. dispersing red 167 dye and sodium poly[(naphthaleneformaldehyde)sulfonate], S2, adding sodium lignosulfonate into the mixture obtained by the step S1 and carrying out mixing, S3, adding sodium carboxymethylcellulose and polysorbate 80 into the mixture obtained by the step S2 and carrying out mixing, S4, adding a cationic surfactant into the mixture obtained by the step S3 and carrying out mixing, and S5, adding water into the mixture obtained by the step S4 and carrying out uniform sand grinding mixing. The dispersing red dye comprises 40-60 parts by weight of the C. I. dispersing red 167 dye and a weight part ratio of the C. I. dispersing red 167 dye to the sodium poly[(naphthaleneformaldehyde)sulfonate] is 1: 0.4-0.6. The C. I. dispersing red 167 dye has a molecular structure formula shown in the description. A mixed network structure of active ingredients is combined with the C. I. dispersing red 167 dye and the composition is firmly bonded to fabric fibers so that color fastness is improved.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing dyes, more specifically, it relates to a preparation process of disperse red dyes. Background technique [0002] With the continuous improvement of living standards, consumers have higher and higher requirements for textiles, including the dyeing effect of textiles. Azo pigments are organic pigments containing azo groups (-N=N-), among which environmentally friendly insoluble azo pigments are a type of azo pigments and are widely used in inks, paints, rubbers, and printing paints. . As a product that is closely related to people's lives, environmentally friendly insoluble azo pigments should provide consumers with products that are safe and beneficial to ecological and environmental protection, and pay attention to the trend of green consumption. [0003] The Chinese patent with application publication number CN105585874A and application publication date of May 18, 2016 discl...
