Abstract

The invention discloses modified dye. The modified dye is characterized by comprising the following components in parts by weight: 100 parts of organic dye material, 5-6 parts of dipropylene glycol, 1-2 parts of glycollic acid, 1-2 parts of ethylene diamine tetraacetic acid, 2-3 parts of green vitriol, 2-3 parts of olive oil, 1-2 parts of EDTA (Ethylene Diamine Tetraacetic Acid) disodium, 2-3 parts of alum, 1-2 parts of hydroxyquinoline, 1-2 parts of peregal, 4-5 parts of additive and 150 parts of water. The modified dye disclosed by the invention has the advantages that the formula is reasonable, the improved production process is simple and easy in implementation, the operability is high, the solubility of the dye is good, the levelling property is good, the salt used amount is less, the environment-friendly effect is achieved, the high-temperature stability is excellent, the effect for dyeing of pure cotton, blended fabrics and polyester-cotton fabrics is good and the quality of the fabric can be obviously improved.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a modified dye and a preparation method thereof. Background technique [0002] Dye is a substance that can make a certain color adhere to the fiber, and it is not easy to fall off and change color. Dyes are usually soluble in water, and some dyes require a mordant to make the dye stick to the fiber. The color of the dye and its affinity with the tissue are determined by the molecular structure of the dye itself. The chromophore that produces the color and the auxochrome that produces the affinity with the tissue together determine the dyeing properties of the dye. As a dye substance, in addition to a chromophoric group, an auxochromic group that ionizes the compound is also required. For example, in dye compounds, chromophoric groups are often formed by nitro (-NO2), azo (-N=N-), vinyl, etc., and acidic groups such as -OH, -SO3H, -COOH and - Basic groups such as NH2, -NHCH3, -N...
