Embodiment 1

[0018] A disperse leveling agent for polyester fibers, comprising the following raw materials in parts by weight: 500 parts of water, 100 parts of styrene phenol polyoxyethylene ether, 100 parts of ammonium lauryl polyoxyethylene ether sulfate and N-alkyl o 350 parts of phthalimide.

[0019] The preparation method of a disperse leveling agent for polyester fibers, adding styrene phenol polyoxyethylene ether, lauryl polyoxyethylene ether ammonium sulfate and N-alkyl phthalimide in sequence to react In the kettle, heat to 80°C, stir well, add water, stir evenly, and cool to room temperature to obtain the finished product.

[0020] A method of using the disperse leveling agent for polyester fibers: add 1-3g / L to the dyeing working solution.

[0021] Water can be used as a solvent to disperse the other raw materials, which can make the disperse leveling agent have better stability under normal conditions, and can be added to the dyeing working solution relatively easily.

Abstract

The invention discloses a dispersing leveling agent for polyester fibers. The dispersing leveling agent comprises following raw materials: an aqueous solvent, a nonionic surfactant, an anionic surfactant, and a plasticizer, which is an organic substance. The preparation method of the dispersing leveling agent is simple. The obtained dispersing leveling agent is applied to a disperse dye, can welldisperse the disperse dye, accelerates the coloring speed of the disperse dye at the same time, and solves the problems that the dyeing on polyester fibers is usually uniform, color spots usually appear on the dyed polyester fibers; and the color difference between different staining jars is relieved.

Description

technical field [0001] The invention relates to a disperse leveling agent for polyester fibers and a preparation method thereof, belonging to the technical field of fabric printing and dyeing. Background technique [0002] Disperse leveling agent is widely used because it can improve the dyeing unevenness and dye coagulation that are easy to occur in the high temperature and high pressure dyeing process of polyester. During the dyeing process, the leveling agent undergoes processes such as the dissolution of the dye, the diffusion of the dye particles in the dye solution, the adsorption on the fabric fiber, the diffusion in the fiber, and the bonding of the dye to the fiber. Polyester microfiber dyeing is prone to the problems of uneven dyeing color such as color flower and color point, and the problem of poor dyeing tank. Choosing the right leveling agent is crucial. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention...
