Embodiment 1

[0032] A special cationic dye composition for modified polyester that integrates level dyeing and deepening, and its preparation method is as follows:

[0033] (1) Mix 30 parts of sodium methylene dimethyl naphthalene sulfonate, 10 parts of Pingpingjia O-25 and 10 parts of benzyltriethylammonium chloride to obtain a cationic dye leveling agent.

[0034] (2) Weigh 1 part of the leveling agent obtained in step (1) and add it to 100 parts of cationic dye red X-GRL, and mix evenly to obtain a cationic dye composition.

Embodiment 2

[0036] A special cationic dye composition for modified polyester that integrates level dyeing and deepening, and its preparation method is as follows:

[0037] (1) Mix 30 parts of sodium methylene dimethyl naphthalene sulfonate, 20 parts of Pingpingjia O-25 and 5 parts of benzyltriethylammonium chloride to obtain a cationic dye leveling agent.

[0038] (2) Weigh 2 parts of the leveling agent obtained in step (1) and add it to 100 parts of cationic dye yellow X-3RL, and mix evenly to obtain a cationic dye composition.

Embodiment 3

[0040] A special cationic dye composition for modified polyester that integrates level dyeing and deepening, and its preparation method is as follows:

Abstract

The invention relates to a level dyeing and color increasing integrated cationic dye composition special for modified polyester. The composition comprises a cationic dye and a leveling agent. The cationic dye composition special for modified polyester is simple in preparation process, is used for dyeing the modified polyester, and has excellent dispersity, retarding property, leveling property andstability, so that the dyed modified polyester is uniform in color, meanwhile, the dyeing depth can be obviously increased, and the quality of a dyed product is stable.

Description

technical field [0001] The invention belongs to the field of cationic dye compositions, in particular to a special cationic dye composition for modified polyester which integrates leveling dyeing and deepening. Background technique [0002] There are no hydrophilic groups in the polyester fiber structure, and the perspiration and air permeability are poor, which affects the wearing experience, and the surface is prone to static electricity, absorbing fine dust, causing fiber stains, and easy to fluff and pilling. In order to improve these deficiencies, researchers used molecular polymerization When adding the third or even the fourth monomer to prepare modified polyester fiber. The modified polyester has soft hand feeling and good anti-pilling performance, and can be dyed with cationic dyes, which greatly improves the application range and application performance of polyester fibers. Cationic dyes have many varieties and low prices, and dyed fabrics have excellent color fas...
