Abstract

The invention discloses a composition for a leveling agent, the leveling agent and a preparation method thereof. The composition for the leveling agent comprises the following raw materials in parts by weight: 15 to 20 parts of polyethylene glycol stearate, 3 to 6 parts of fatty amine polyoxyethylene ether, 6 to 8 parts of polysorbate, 2 to 4 parts of sodium dodecyl benzene sulfonate, and 35 to 40 parts of deionized water. The invention also provides a method for preparing the leveling agent by using the composition. The method for preparing the leveling agent by using the composition comprises the following steps of adding the polyethylene glycol stearate, the fatty amine polyoxyethylene ether, the polysorbate and the dodecyl benzene sulfonate into a reaction kettle with an agitator in sequence, mixing and agitating an obtained mixture, and adding the deionized water into the obtained mixture while agitating the obtained mixture. The invention also provides the leveling agent, which is prepared according to the method. Matching raw materials of the composition for the leveling agent are a few, and are simple and easy to obtain; the preparation cost is low; the prepared leveling agent is good in retarding, migration and dispersion effects; further, the reparation method is simple.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a composition for a leveling agent, a leveling agent and a preparation method thereof. Background technique [0002] During the dyeing process of fiber yarn, thread or fabric, a substance added to promote uniform dyeing and avoid color stripes, stains and other defects is a leveling agent. Most leveling agents are water-soluble surfactants. According to the influence of leveling agents on dye diffusion and aggregation, they are mainly divided into two types: pro-fibril leveling agents and dye-friendly leveling agents. For the leveling agent used in polyester high-temperature and high-pressure dyeing, there are generally disadvantages of relatively complicated formula and high production cost. Contents of the invention [0003] A brief overview of the invention is given below in order to provide a basic understanding of some aspects of the invention. It should be understood that this summa...
