Problems solved by technology
[0005] The purpose of the present invention is to solve the disadvantages of the prior art that the molecular attraction between the cationic dye and the fiber is small, the dye uptake of the cationic dye is obviously decreased, and the washing fastness is low, and a kind of high dye uptake, high light fastness and washing fastness is provided. Composite cationic dye composition with high fastness. The composite cationic dye composition has reasonable compatibility, strong molecular attraction with fibers, and high dye uptake rate. The cationic dye is not easy to detach from the fiber after washing the fabric after dyeing.

The invention relates to a compound cationic dye composition and particularly relates to a compound cationic dye composition with high dye-uptake rate, high light fastness and high washing fastness. The compound cationic dye composition aims at solving the defects of small molecular attraction between cationic dye and fiber, obvious reduction of dye-uptake rate of the cationic dye and low washing fastness in the prior art. The compound cationic dye composition comprises the following components in percent by weight: 10-40% of cationic blue X-GRRL shown in a formula (1), 5-30% of cationic red shown in a formula (2), 10-20% of cationic yellow shown in a formula (3), 1-10% of cationic red shown in a formula (4) and the balance of aids. The compound cationic dye composition disclosed has the advantages that the compatibility is reasonable, the molecular attraction with the fiber is large, the dye-uptake rate is high, the dyed cloth is washed and the cationic dye is not easily separated from the fiber.
Description
technical field [0001] The invention relates to a composite cationic dye composition, in particular to a composite cationic dye composition with high dye uptake, high light fastness and washing fastness. Background technique [0002] Cationic dyes are a kind of textile dyes, also known as basic dyes and salt-based dyes, which are in a cationic state when dissolved in water. They are mainly used for dyeing acrylic fibers, and can also be combined with protein molecules with salt and alkali. Cationic dyes It is soluble in water and ionized in aqueous solution to generate positively charged colored ions. The cation of the dye can combine with the acidic group of the third monomer in the fabric to dye the fiber. It is a special dye for acrylic fiber dyeing. It has It has the advantages of high strength, bright color and good light fastness. [0003] With the recent rapid development of polyester fibers, superfine fibers and superfine denier fibers have appeared. Due to their ex...
