Abstract

The invention relates to a multi-functional dye leveler for one bath degreasing dyeing of polyester fiber and a preparation method thereof. The dye leveler comprises PEG 300 lauric acid ester, sodium lignin sulfonate, soil temperature 60, polyaspartate, calcined soda and water, has the functions such as migration, scattering, chelating, degreasing, purging and the like, can be used for dying polyester fiber, simplifies the traditional technology and is conducive to energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a reagent for the textile dyeing and finishing industry and a preparation method thereof, in particular to a multifunctional leveling agent used for one-bath deoiling and dyeing of polyester fibers and a preparation method thereof. Background technique [0002] The printing and dyeing industry is an important component of the textile industry, and it is also an industry with high energy consumption and large sewage discharge. In advanced countries, the water consumption per ton of fiber printing and dyeing is about 100 tons, while in my country it is generally 300-400 tons. Therefore, it is imperative to implement energy conservation and emission reduction in the printing and dyeing industry. [0003] In the printing and dyeing industry to carry out energy saving and emission reduction work, in addition to research and development of high-efficiency, water-saving, and energy-saving equipment, and the development and promotion o...
