Description

technical field [0001] The invention relates to the technical field of surfactants, in particular to pentadecyl (enyl) meta-diphenol (cardol) polyoxyethylene ether ammonium sulfate and a preparation method and application thereof. Background technique [0002] Most leveling agents are water-soluble surfactants. According to the influence of leveling agents on dye diffusion and aggregation, they are mainly divided into two types: one is fibrophilic leveling agent, which has almost no effect on the aggregation of dyes. No effect. However, the affinity for fibers is greater than that of dyes for fibers. Therefore, during the dyeing process, such leveling agents will first combine with fibers to reduce the dyeing rate of dyes. However, with the change of dyeing conditions, dyes will Gradually replace the leveling agent and fix it on the fiber. This type of leveling agent only has the effect of retarding the dyeing; the second is the dye-friendly leveling agent. It can significan...
