NOVELTY - Preparing anti-fouling and oil-resistant textile fabrics comprises uniformly mixing basic fiber and anti-fouling filler fiber in a weight ratio of 1:0.7-2.8 and weaving to make it. The preparation method of the basic fiber comprises (1) preparing polyurethane emulsion with solid content of 12-17%, adding polyester fiber to it, ultrasonically processing it at 30-50 KHz for 5-15 minutes, allowing it stand for 20-27 minutes, filtering out the fiber, and taking it out, and drying at the temperature of 60-65 times, and (2) preparing sodium hydroxide solution in a mass concentration of 3-8.5%, adding cetyltrimethylammonium chloride to it, where the concentration of cetyltrimethylammonium chloride is 2-2.5 g/l, stirring, mixing and dispersing, adjusting the temperature to 60-80 degrees C, adding the polyester fiber treated in the step (1) to it, dipping it for 10-18 minutes, and washing the fibers with deionized water and hot ethanol for 1-5 times after filtering. USE - The method is useful for preparing anti-fouling and oil-resistant textile fabrics. ADVANTAGE - The method does not obviously affects the ventilation property and flexibility of the active carbon fiber. DETAILED DESCRIPTION - Preparing anti-fouling and oil-resistant textile fabrics comprises uniformly mixing basic fiber and anti-fouling filler fiber in a weight ratio of 1:0.7-2.8 and weaving to make it. The preparation method of the basic fiber comprises (1) preparing polyurethane emulsion with solid content of 12-17%, adding polyester fiber to it, ultrasonically processing it at 30-50 KHz for 5-15 minutes, allowing it stand for 20-27 minutes, filtering out the fiber, and taking it out, and drying at the temperature of 60-65 times, (2) preparing sodium hydroxide solution in a mass concentration of 3-8.5%, adding cetyltrimethylammonium chloride to it, where the concentration of cetyltrimethylammonium chloride is 2-2.5 g/l, stirring, mixing and dispersing, adjusting the temperature to 60-80 degrees C, adding the polyester fiber treated in the step (1) to it, dipping it for 10-18 minutes, washing the fibers with deionized water and hot ethanol for 1-5 times after filtering, and drying at a temperature of 50-65 degrees C to obtain surface-treated polyester fibers, where the temperature of the hot ethanol is 55-65 degrees C, (3) adding maleic anhydride to NN dimethylformamide, mixing and stirring to dissolve, adding the surface-treated polyester fiber treated in the step (2) to it, ultrasonically processing it at frequency of 20-30 KHz for 7-10 minutes, raising the reaction temperature to 90-100 degrees C, reacting for 2-4 hours, taking out the surface-treated fiber by solid-liquid separation, washing with propanol and drying to obtain grafted modified polyester fiber, (4) uniformly mixing absolute ethanol and deionized water in a volume ratio of 1:0.9-0.99, adding fluorosilane coupling agent to it, mixing and uniformly dispersing, prehydrolyzing at 30-35 degrees C for 20-30 minutes, adding nano-silicon dioxide to it, and treating it for 15-25 minutes under the conditions of temperature of 30-35 degrees C, and performing ultrasonic frequency of 60-160 KHz to obtain treatment solution, and (5) adding the graft-modified polyester fiber prepared in the step (3) to the treatment solution obtained in the step (4), ultrasonically treating at ultrasonic frequency of 20-35 KHz for 20-30 minutes at temperature of 75-90 degrees C, keeping the temperature and allowing to stand for 30-50 minutes, washing with deionized water after solid-liquid separation, and drying at 60-75 degrees C to obtain basic fiber. An INDEPENDENT CLAIM is also included for anti-fouling and oil-resistant textile fabric processed and prepared by the above preparation method.
