Abstract

The invention provides a leveling agent and a preparation method thereof. The preparation method comprises the following steps: (1) mixing hydromica, halloysite, talcum powder, sodium bentonite and isopropanol, and grinding the mixture; (2) washing the ground mixture with water, filtering and then drying; (3) screening the product with a 200-mesh sieve for removing large particles; (4) mixing thescreened product with sodium fluosilicate, sodium caseinate, sodium selenate, sodium ferulate, xylitol and deionized water, heating and stirring for carrying out a reaction; (5) putting the reaction products into a centrifugal machine for carrying out centrifugal separation, and removing supernatant; (6) adding spherical nano titanium dioxide, sodium lauryl sulfate, polyvinyl alcohol, N-methyl pyrrolidone, sodium stearoyl lactylate, diacetyl tartaric acid monoglyceride, fatty alcohol polyoxyethylene ether, ylang ylang oil and the remaining deionized water, and stirring at the high speed to obtain the leveling agent. The leveling agent provided by the invention is uniform in dyeing to fabric, good in level dyeing effect, and high in level of dry and wet rubbing fastness; furthermore, afterbeing washed with water, the leveling agent enables the color not to be changed basically, does not stain, and has very high fastness to washing.

Description

technical field [0001] The invention relates to the field of textile materials, in particular to a leveling agent and a preparation method thereof. Background technique [0002] Textile auxiliaries are very important to increase the added value of textiles. They can not only make textiles functional, but also make them upscale and more contemporary. However, the prerequisite for these advantages is that the dyeing of the fabric must be even and transparent. Leveling agent to achieve. 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, but the affinity for fibers is greater than that of dyes for fibers. Therefore, during the dyeing process, this type of leveling agent will first combine with fibers to reduce the dyeing rate of dyes. This type of leveling age...
