Abstract
The invention relates to a brightening dispersion auxiliary agent used for color masterbatches and color powder. The brightening dispersion auxiliary agent comprises the following components, and the weight percentage of each component is 70%-80% of stearic acid, 20%-25% of ethanediamine; 1% of an anti-oxidant, 2%-3% of a grafted polymer and 0.1% of an initiator. The auxiliary agent is used in the color masterbatches such as PP (polypropylene fiber), PA (polyamide fiber) and PET (polyester fiber). For processing properties, the auxiliary agent can reduce current and torque when materials are made, and improves melt index of the materials. The auxiliary agent can disperse organic pigments effectively at relatively low addition, improves glossiness of the color masterbatches, decreases a DF value (filtering experiment value) of the color masterbatches, and can prolong screen-changing time in a downstream spinning process.
