Description
Technical Field
The invention relates to a preparation method of a high-temperature leveling agent, belonging to the technical field of textiles.
Background
the polyester fiber is the synthetic fiber with the widest application field and the largest output at present. Because the polyester macromolecular structure of the polyester fiber is compact and the hydrophobicity is strong, the polyester fiber can not be dyed at normal pressure like other fibers, and the polyester fiber is dyed by adopting disperse dye in a high-temperature mode. In addition, in order to save resources and further improve labor productivity, a rapid dyeing method of terylene is mostly adopted, but rapid dyeing is not easy to level, and a leveling agent with excellent dispersibility is required to be added so as to prevent dye from coagulating and have excellent dye transfer performance. The different physical forms of the dyes have great influence on the solubility and the high-temperature dispersion stability of the dyes in water, and directly influence the dyeing properties such as leveling property, dye uptake, lifting property and the like, especially on the terylene superfine fibers.
At present, most high-temperature leveling agents are compounded by anions and nonionic compounds, and the leveling effect is achieved by utilizing the functions of slow dyeing and dye transfer of the nonionic and the dispersing function of the anions. Most of high-temperature leveling agents in the market are aromatic compounds and compounds thereof, can achieve a certain leveling effect, but the leveling effect is not ideal. Therefore, it is necessary to research a high-efficiency high-temperature leveling agent. Patent publication No. 103741519A discloses a high-temperature leveling agent, which is composed of fatty alcohol polyoxyethylene ether, hydroxypropyl methyl cellulose, ethylene glycol fatty acid ester, fatty amine polyoxyethylene ether, isomeric alcohol polyoxyethylene ether, glycerol trioleate and tartaric acid in different proportions. But the level dyeing effect is not good, and the slow dyeing, the transfer dyeing and the dispersion effect are poor.
In addition, a plurality of high-temperature leveling agents such as glyceryl ether oleate is compounded with styryl phenol polyoxyethylene ether sulfate to form GS; a high-temperature leveling agent FZ compounded by fatty alcohol-polyoxyethylene ether and sodium alkyl benzene sulfonate, and the like. The high-temperature leveling agents are all relatively excellent and commonly used products in the market, and have various advantages in effect performance-price ratio. For example, the GS type is one of the types which are widely used in the current market, and the dyeing requirement can be met when the general usage amount is about 0.5 percent. However, although the high-temperature leveling agents have certain effects, and the GS and FZ types have good effects, the high-temperature leveling agents contain styrol and phenol substances, and the styrol and phenol components are difficult to degrade and are not environment-friendly, and belong to international banned products.
