Abstract

The invention discloses a printing black dye. The printing black dye comprises, by weight, 40 to 60 parts of a C. I. disperse blue 79 dye, 30 to 50 parts of a C. I. disperse orange 44 dye, 5 to 20 parts of a C. I. disperse purple 93 dye, 10 to 27 parts of sodium lignin sulfonate, 5.25 to 28 parts of lignin and 60 to 75 parts of water. The C. I. disperse blue 79 dye has a structural formula shown in the description. The C. I. disperse orange 44 dye has a structural formula shown in the description. The C. I. disperse purple 93 dye has a structural formula shown in the description. Lignin contains an active group, has a long chain structure on the side chain and has a structure similar to that of sodium lignin sulfonate. Based on the principle of dissolution in the similar material structures, sodium lignin sulfonate connection is formed and full contact and binding of sodium lignin sulfonate and lignin to the mixed dye is realized through electron donating and electron withdrawing groups. Through a large amount of hydroxyl groups, the mixed dye bonded to the sodium lignin sulfonate and lignin can be firmly bonded to fabric fibers so that the dye is firmly fixes to the fabric fibers and the fabric has excellent color fastness.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing dyes, more specifically, it relates to a printing black dye and a blending process thereof. 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, 2...
