Embodiment 1

[0035] Prepare the following raw materials in parts by weight: 10 parts of fatty alcohol polyoxyethylene ether, 30 parts of fatty amine polyoxyethylene ether, 5 parts of toluene, 3 parts of sodium benzoate, 3 parts of ethoxylated lanolin, 3 parts of sodium sulfate, sodium acetate 0.5 parts, 5 parts of N-methylpyrrolidone and 100 parts of water.

[0036] Under normal temperature conditions, add each raw material into water, stir at high speed to obtain an emulsion, control the speed of high-speed stirring at 1000r / min; heat the emulsion to 60°C under stirring, then quickly cool down to -2°C in 50s, and then slowly heat up to room temperature That's it.

Embodiment 2

[0038] Prepare the following raw materials in parts by weight: 30 parts of fatty alcohol polyoxyethylene ether, 10 parts of fatty amine polyoxyethylene ether, 10 parts of toluene, 1 part of sodium benzoate, 5 parts of ethoxylated lanolin, 0.5 part of sodium sulfate, sodium acetate 2 parts, 1 part of N-methylpyrrolidone, 5 parts of chitosan, 1 part of tiger piranha powder and 250 parts of water. The chitosan has a weight-average molecular weight of 2kDa, a deacetylation degree of 95%, and a particle size of 200nm; the tiger Pilan powder has a particle size of 500nm.

[0039] Under normal temperature conditions, add each raw material into water, stir at high speed to obtain an emulsion, control the speed of high-speed stirring at 1500r / min; heat the emulsion to 50°C under stirring, then quickly cool down to 0°C in 30s, and then slowly heat up to room temperature. Can.

Embodiment 3

Abstract

The invention provides a levelling agent and a preparation method and application thereof. The levelling agent comprises, by weight, 10-30 parts of fatty alcohol polyoxyethylene ether, 5-10 parts of toluene, 1-3 parts of sodium benzoate, 3-5 parts of ethoxylated lanolin, 0.5-3 parts of sodium sulfate, 0.5-2 parts of sodium acetate, 1-5 parts of N-methyl pyrrolidone and 100-250 parts of water. Thepreparation method includes: adding various raw materials into water at normal temperature, and stirring at high speed to obtain an emulsion; heating the emulsion to 50-60 DEG C while stirring, fast cooling to -2-0 DEG C, and slowing heating to normal temperature. The levelling agent is used for fabric dyeing. The levelling agent does not aggregate with dye and is good in levelling effect. The preparation method is simple to operate, and the prepared levelling agent is good in stability and wide in application range.

Description

technical field [0001] The invention relates to the field of printing and dyeing, in particular to a leveling agent and its preparation method and application. Background technique [0002] Leveling agent is one of the most commonly used surfactants in the textile industry. Its main function is to ensure that the color depth, shade and brightness of the entire surface of the fabric are consistent during the dyeing process, and to avoid defects such as color stripes and stains. [0003] There are many kinds of leveling agents in the prior art, which are mainly divided into two types: pro-fiber and pro-dye, such as leveling agents containing ethoxy structures, leveling agents containing styrylphenol polyoxyethylene ethers, and aliphatic compounds Leveling agent, etc. [0004] When the existing leveling agent is used, it is easy to aggregate with the dye, which not only reduces the permeability, but also affects the diffusion speed of the dye, resulting in the insignificant im...
