Fabric leveling agent for acid dye

Abstract

The invention discloses a fabric leveling agent for an acid dye. The fabric leveling agent is prepared from the following materials by mass percent: 6 to 12 percent of styryl phenol polyoxyethylene ether ammonium sulfate, 3 to 8 percent of octadecylamine polyoxyethylene ether sodium laureth sulfate, 6 to 10 percent of peregal O, 2 to 6 percent of polyoxyethylene ether glycerol oleate, 5 to 10 percent of polyoxyethylene hydrogenated lanolin and the balance of deionized water. The fabric leveling agent is suitable for leveling acid and neutral dyes, good in leveling performance and stability, easy to dissolve at the normal temperature and convenient to use; and a leveling agent system is good in hard water resistant stability, good in affinity to dyes and wool fibers, favorable for dispersing and retarding the dye and capable of improving the utilization rate of the dye.

Description

technical field [0001] The invention relates to the field of auxiliary agents for textile processing, in particular to a fabric leveling agent for acid dyes. Background technique [0002] When various dyes are used for fiber dyeing, uneven dyeing often occurs, resulting in colored flowers. The most commonly used method to solve uneven dyeing is to add leveling agent during dyeing process. Leveling agent is a textile auxiliary that can slow down the dyeing speed or enhance dyeing migration in the dyeing process to obtain a uniform dyeing effect. Different dyes and dyeing processes require different leveling agents in the fiber dyeing process. [0003] Acid dye molecules contain acid groups such as sulfonic acid groups and carboxyl groups in the form of organic acid salts. Because of their high affinity to fibers, it is difficult to dye evenly, so they need to be treated with leveling agents. When acid dyes are used to dye wool fibers, due to the existence of the hydrophobic...

Problems solved by technology

When acid dyes are used to dye wool fibers, due to the existence of the hydrophobic outer skin layer and dense scale layer of the fibers, as well as the differences in the wool fibers themselves, there are differences in the affinity of the fibers to the dyes, which may easily cause uneven dyeing and color differences at the root and tip of the hair. Problem; when dyeing nylon with acid dyes, because the dye mole
