Abstract

The invention provides an organic silicon deep dyeing promoter and a preparation method thereof. The organic silicon deep dyeing promoter is prepared by the following steps: firstly mixing hexadecyl trimethyl ammonium bromide, dodecyl ammonium chloride, methyl glucose sesquistearate and oleic acid polyoxyethylene ester with deionized water, and mixing for 30-50 minutes; adding nanosilicon dioxide, sodium silicate and octamethylcyclotetrasiloxane, and stirring for 10-30 minutes at high speed; adding vinyl triethoxysilane and vinyl trimethoxy silane, continuously stirring for 10-20 mintues at high speed, homogenizing for 10-30 minutes, and heating to 80-85 DEG C; adding tetramethylammonium hydroxide, stirring for 5-10 minutes, preserving the temperature for 3-4 hours, and cooling down; adding potassium sorbate and phytic acid, and stirring for 10-20 minutes; and finally adding glacial acetic acid to neutralize to be neutral, thereby obtaining the organic silicon deep dyeing promoter. The prepared organic silicon deep dyeing promoter has relatively lower brightness value, excellent deep dyeing promotion effect, and also has excellent wash resistance.

Description

technical field [0001] The invention relates to the field of textile materials, in particular to a silicone darkening agent and a preparation method thereof. Background technique [0002] Polyester fiber fabric is a synthetic fiber obtained by spinning polyester, which is formed by polycondensation of organic dibasic acid and dibasic alcohol. Compared with other textile fabrics, it has many advantages, such as low price, high strength, and strong heat resistance. , high dimensional stability, strong wrinkle resistance and good color fastness and other excellent characteristics, it is currently the most widely used synthetic fiber in the textile industry. But a big disadvantage of polyester fiber is that it is poor in dyeing dark color, especially black and other dark fabrics. Boundless visual effects. Especially in recent years, the production of fine and superfine polyester fibers and the appearance of polyester fiber imitation silk products have been welcomed and sought ...
