The water and oil repellent can be applied to the substrate by any known method of treating the substrate with a liquid. The substrate can be immersed in the water and oil repellent, or the solution can be attached or sprayed onto the substrate. To exhibit liquid repellency, it is preferable to heat and dry and harden the treated substrate. The heating temperature can be, for example, 100°C to 200°C, 100°C to 170°C, or 100°C to 120°C. Even low-temperature heating (e.g., 100°C to 140°C) can obtain good performance in the present disclosure. In the present disclosure, the heating time can be 5 seconds to 60 minutes, for example, it can be 30 seconds to 3 minutes. When the substrate is paper, it can be coated on the paper, or the solution can be attached or sprayed onto the paper, or before papermaking, it can be mixed and treated with the pulp slurry. The treatment can be an external treatment or an internal treatment. Alternatively, the water and oil repellent can be applied to the fiber product by a cleaning method, for example, it can be applied in a washing or dry cleaning method or the like to the fiber product. 〔Treatment of paper products〕 Examples of the paper substrate include: paper, paper containers, paper molded articles (such as pulp molds), etc. The fluorine-containing compound of the present disclosure can adhere well to the paper substrate. Paper can be manufactured by traditional known papermaking methods. An internal treatment method of adding a water and oil repellent to the pulp slurry before papermaking or an external treatment method of applying a water and oil repellent to the paper after papermaking can be used. The sizing machines for the external treatment method can be classified into the following types according to the coating method. One coating method is to supply the coating liquid (sizing liquid) to the nip part formed between two rubber rollers through which the paper passes, form a coating liquid pool called a pond, and pass the paper through this coating liquid pool to coat the sizing liquid on both sides of the paper, that is, the so-called pond-type two-roll sizing machine. Another coating method is the gate roll type and the rod-type metering sizing machine that transfer the sizing liquid by surface transfer. In the pond-type two-roll sizing machine, the sizing liquid easily penetrates into the interior of the paper, while in the surface transfer type, the sizing liquid easily stays on the surface of the paper. Compared with the pond-type two-roll sizing machine, the coating layer in the surface transfer type easily stays on the surface of the paper, and the coating layer formed on the surface is more than that of the pond-type two-roll sizing machine. In the present disclosure, even if the former pond-type two-roll sizing machine is used, performance can be imparted to the paper. The paper treated in this way can be arbitrarily heat-treated at up to 300°C, for example, 200°C, especially in the temperature range of 80°C to 180°C, after simple drying at room temperature or high temperature, and can exhibit excellent oil resistance and water resistance, etc. The internal addition treatment method refers to a treatment method in which a water and oil repellent is added to the pulp slurry before papermaking. The internal addition treatment method may include: a step of adding a water and oil repellent to the pulp slurry and then stirring and mixing, a step of dewatering the pulp composition prepared in this step by suction through a mesh with a predetermined shape to form a pulp mold intermediate, and a step of forming and drying the pulp mold intermediate with a heated forming mold to obtain paper, a paper container, or a paper formed article, but is not limited thereto. After the treated paper is simply dried at room temperature or high temperature, heat treatment can be arbitrarily performed according to the properties of the paper. The temperature of the heat treatment can be 150 °C or higher, 180 °C or higher, or 210 °C or higher. In addition, it can be 300 °C or lower, 250 °C or lower, or 200 °C or lower, particularly 80 °C to 180 °C. By performing heat treatment in this temperature range, excellent oil resistance and water resistance can be exhibited, etc. This disclosure can be used in base paper for gypsum board, coated base paper, medium paper, ordinary base paper and core materials, neutral pure white roll paper, neutral base paper, rust-proof base paper and metal laminated paper, kraft paper, etc. In addition, it can also be used in neutral printing and writing paper, neutral coated base paper, neutral PPC paper, neutral thermal paper, neutral pressure-sensitive base paper, neutral inkjet paper, and neutral information paper, etc. As the pulp raw material, any one of bleached or unbleached chemical pulps such as kraft pulp or sulfite pulp, waste paper pulps such as groundwood pulp, mechanical pulp or thermomechanical pulp, waste paper pulps such as old newspapers, old magazine papers, old cardboard waste papers or deinked waste papers can be used. In addition, a mixture of the above pulp raw materials and synthetic fibers such as asbestos, polyamide, polyimide, polyester, polyolefin, and polyvinyl alcohol can also be used. In addition to the sizing agent, the water resistance of the paper can also be improved. Examples of the sizing agent are: cationic sizing agent, anionic sizing agent, rosin sizing agent (for example, acidic rosin sizing agent, neutral rosin sizing agent). The amount of the sizing agent relative to the pulp can be 0.01 to 5% by weight. As papermaking chemicals for the general usage degree required for paper, sizing agents, flocculants, fixatives, yield improvers, dyes, fluorescent dyes, slime control agents, defoamers, etc. used in the manufacture of paper, such as starch, modified starch, carboxymethyl cellulose, polyamide polyamine-epichlorohydrin resin, etc., can be used. It is preferably to use starch and / or modified starch. When needed, starch, polyvinyl alcohol, dyes, coating coloring, anti-slip agents, etc. can be used, and the water and oil repellent is coated on the paper with a size press, a gate roll coater, a blade coater, a calender, etc. In external addition, the amount of the fluorine compound contained in the coating layer is 0.01 to 2.0 g / m 2 is preferred, and 0.1 to 1.0 g / m 2is particularly preferred. The coating layer is preferably formed from a water and oil repellent, starch, and / or modified starch. The solid content of the water and oil repellent for paper in the coating layer is 2 g / m 2 is preferred as follows. In internal addition, preferably, relative to 100 parts by weight of the pulp forming the paper, the amount of the water and oil repellent is made 0.01 to 50 parts by weight or 0.01 to 30 parts by weight, for example, 0.01 to 10 parts by weight, particularly 0.2 to 5.0 parts by weight, and the water and oil repellent and the pulp are mixed. In external addition, the treatment liquid is stored between the rollers. Even if the base paper is passed through the treatment liquid between the rollers at an arbitrary roller speed and nip pressure, that is, the so-called pond-type two-roll sizing machine treatment, oil resistance can be imparted to the paper. In external addition treatment, the paper substrate may contain additives such as a sizing agent, a paper strength enhancer, a coagulant, a retention aid, or a flocculant. The additives can be nonionic, cationic, anionic, or amphoteric. The ionic charge density of the additives can be -10,000 to 10,000 μeq / g, preferably -4,000 to 8,000 μeq / g, more preferably -1,000 to 7,000 μeq / g. Usually, additives (for example, a sizing agent, a paper strength enhancer, a coagulant, a retention aid, or a flocculant. For example, the solid content or the active ingredient) in an amount of 0.1 to 10% by weight (for example, 0.2 to 5.0% by weight) can be used relative to the pulp.
