Abstract

The invention discloses a textile deepening agent and a preparation method thereof. The textile deepening agent comprises the following steps of: 1) mixing nano silica, a silicane coupler and alcohol, and reacting for 16-30 hours at a temperature of 10 DEG C to 35 DEG C to obtain silicane coupler modified nano silica solution; 2) using methyl methacrylate to displace alcohol, adding butyl acrylate, hexadecane and water, after uniformly mixing, mixing with dodecy sodium sulfate water solution, and obtaining emulsion after the mixture is dispersed; and 3) under the protection of protective gas, increasing a temperature of the emulsion to 50 DEG C to 90 DEG C, adding potassium peroxydisulfate water solution, initiating a polymerization reaction, and obtaining the textile deepening agent after reacting for 2-4 hours at the temperature of 50 DEGC to 90 DEG C. The preparation method is simple, is easy to implement, and is easy to be applied in the industrialized large-scale production. The invention further discloses a textile deepening agent, a silica particle is connected with a polymer through the surface silicane coupler, so that the coloring efficiency of a dye is increased, a color of dyeing textile is deepened, and the textile is provided with a remarkable washing resistant property.

Description

technical field [0001] The invention relates to the field of textile auxiliaries and its preparation, in particular to a fabric darkening agent and its preparation method. Background technique [0002] When natural fibers (such as silk) are dyed into dark colors, reactive dyes are often used to improve color fastness. In order to increase the color depth, it is generally achieved by increasing the concentration of the dye. However, the deepness of reactive dyeing is poor, and even when the amount of dye is as high as 6% (based on cloth weight), the color depth of the fabric still cannot meet the requirements, and thus the color fastness of dark fabrics is not up to standard, and the amount of dye is too large. Waste and increased burden on sewage treatment and many other issues. [0003] Fabric darkening refers to a finishing method that realizes the darkening of fabrics without adding dyes. It not only saves dyes and reduces production costs, but also reduces the content ...
