Antibacterial waterproof functional polyester fabric and preparation method thereof

The antibacterial waterproof functional polyester fabric is prepared from the following components in parts by weight: 25 to 35 parts of polyester fibers, 15 to 22 parts of polyamide fibers, 18 to 26 parts of cotton fibers, 5 to 11 parts of sisal fibers, 12 to 22 parts of triacetate fibers, 1 to 5 parts of a waterproof agent, 2 to 6 parts of nano bamboo charcoal fibers and 3 to 5 parts of nano titanium dioxide powder, according to the antibacterial and waterproof functional polyester fabric, a waterproof agent and nano bamboo charcoal fibers are added in the dyeing process of the prepared polyester fabric, finally after-treatment is conducted, nano titanium dioxide powder is applied to the fabric, and the polyester fabric is endowed with the excellent performance of water repellency, antibacterial performance and solarization resistance. According to the device, impurities attached to the surface of the polyester fabric can be effectively scraped and cleaned, so that the situation that the quality of the fabr
