Problems solved by technology

Therefore, when a large amount of petroleum-based surfactants are used as leveling agents when dyeing various dyes, while obtaining the leveling effect, a large amount of surfactants with poor biodegradability remain in the printing and dyeing wastewater, giving The treatment of printing and dyeing wastewater brings difficulties, which in turn will cause environmental impact
In addition, leveling agents such as leveling agent OP and other alkylphenol polyoxyethylene ethers are considered to be environmental hormones, and there is a risk of harm to humans.
[0005] Moreover, in the traditional leveling agent formula, there are still problems such as high cost, complicated process, and poor leveling effect.

Abstract

The invention relates to the technical field of textile printing and dyeing materials and particularly discloses an acidic leveling agent and a preparation method thereof. The acidic leveling agent is prepared from the following components by weight percent: 10.0%-20.0% of an emulsifying agent, 20.0%-45.0% of fatty amine, 8.0%-10.0% of sulfamic acid, 5.0%-8.0% of fatty alcohol, 3.0%-5.0% of urea and the balance of water. The preparation method comprises the following steps: adding the raw materials except water into a reaction kettle in sequence according to the formula and stirring; when adding each type of raw material, stirring for 20-25 minutes; weighing the water amount needed in the formula and adding into the reaction kettle; stirring and reacting for 1 hour; and after finishing, standing and filtering and discharging materials. The acidic leveling agent disclosed by the invention has extremely good diffusivity and mobility, so that dye molecules are uniformly combined with fiber molecules in a dyeing process; the acidic leveling agent is wide in applicability, good in effect and environmentally friendly; and compared with a traditional formula, the agent has the advantages that 10%-15% of the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing materials, in particular to an acidic leveling agent and a preparation method thereof. Background technique [0002] In the dyeing process of fiber yarn, thread or fabric, it is often necessary to add a leveling agent in order to promote uniform dyeing and avoid defects such as color stripes and stains. [0003] The main purpose of level dyeing is: to make the dye molecules evenly distributed on the surface of the fiber; to make the dye distributed on the surface of the fiber diffuse to the inside of the fiber. The above goals can be achieved by controlling the dyeing speed, controlling the uniform concentration and temperature of the dye bath, using dyes with good dye transfer properties, using dye transfer agents and carriers, and dyeing at high temperature for a long time. [0004] The leveling mechanism of the leveling agent has two aspects: one is to reduce the diffusion ...
