Abstract

The invention discloses a leveling agent. The leveling agent comprises the following raw materials in percentages by mass: 7%-10% of dodecyl alcohol polyoxyethylene ether, 5%-9% of 2-naphthalene sulfonic acid formaldehyde polymer sodium salt, 1%-3% of isopropanol, 0.5%-1% of chondroitin sulfate, 2%-6% of sodium dihydrogen phosphate and the balance of water, and the sum of the contents of the foregoing raw materials should be 100%. The invention also discloses application of the leveling agent in polyester dyeing. The leveling agent has the beneficial effects that a leveling agent method is used for pure cotton dyeing, the dyeing time can be shortened, and the leveling effect is excellent; and chondroitin is used in the technical field of printing and dyeing, and the application market value of the chondroitin is widened.

Description

technical field [0001] The invention belongs to the technical field of dyeing auxiliaries, in particular to a leveling agent, and also relates to the application of the above-mentioned leveling agent in polyester dyeing. Background technique [0002] According to the different affinity between the leveling agent and the dye and fiber, the leveling agent is mainly divided into the following two categories: (1) Fibrophilic leveling agent, which has almost no effect on the aggregation degree of the dye, and has a greater affinity to the fiber than the dye Therefore, in the dyeing process, this kind of leveling agent will first combine with the fiber to reduce the dyeing rate of the dye, but as the dyeing conditions change, the dye will gradually replace the leveling agent and fix on the fiber. (2) Dye-friendly leveling agent can significantly increase the degree of dye aggregation, and its affinity for dyes is greater than that of dyes for fibers. Before dyeing, the leveling ag...
