Bamboo charcoal powder-based false eyelashes and preparation process thereof

A false eyelash, comprising the following raw materials in percentage by mass:

• 90-96% of polyester matrix made by polyester particles, 3-8% of bamboo charcoal powder and 1-2% of adjuvant;
• wherein the adjuvant is represented by
• and the adjuvant is prepared by the following steps:
• S1, adding isocyanopropyl triethoxysilane, 3-chloro-1-propanol and N,N-dimethylamide into a flask under the protection of nitrogen at room temperature, adding triethylamine after stirring, heating to 75° C., reacting for 3 h, cooling to room temperature, and then distilling at reduced pressure to obtain intermediate 1;
• S2, adding the intermediate 1 and dimethyl sulfoxide into a flask under the protection of nitrogen at room temperature, stirring and heating to 40° C., then adding tetradecyl dimethyl tertiary amine, heating to 50° C. and reacting for 8 h, cooling to room temperature, distilling at reduced pressure, purifying via column chromatography, and then distilling at reduced pressure to obtain intermediate 2;
• and
• S3, adding the intermediate 2, triclosan and tetraisopropoxy titanium into a flask equipped with toluene, reacting for 24 h at 90° C., cooling to room temperature and then washing with tartaric acid followed by washing with sodium bicarbonate, drying, filtering, distilling at reduced pressure, purifying via column chromatography, and then distilling at reduced pressure to obtain the adjuvant
