Effect of the Invention

[0006] The oil-resistant agent of the present disclosure can impart oil resistance to a substrate (e.g., fiber, paper). DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] <Terminology> As used herein, the term "n-valent group" refers to a group having n bonds, i.e., a group that forms n bonds. The term "n-valent organic group" refers to an n-valent group containing carbon. Such an organic group is not particularly limited, but may be a hydrocarbon group or a derivative thereof. The derivative of a hydrocarbon group refers to a group having one or more N, O, S, Si, amide, sulfonyl, siloxane, carbonyl, carbonyloxy, etc. at the end of the hydrocarbon group or in the molecular chain.

[0008] As used herein, the term "hydrocarbon group" refers to a group containing carbon and hydrogen, which is a group obtained by removing a hydrogen atom from a hydrocarbon. Such a hydrocarbon group is not particularly limited, but includes, for example, C 1-20 Examples of the hydrocarbon group include an aliphatic hydrocarbon group and an aromatic hydrocarbon group. The above-mentioned "aliphatic hydrocarbon group" may be linear, branched, or cyclic, and may be saturated or unsaturated. The cyclic group may include a chain structure. The hydrocarbon group may be substituted with one or more substituents.

[0009] In this specification, when a term (symbol) that may occur multiple times in a chemical structure is defined, that definition applies independently to each occurrence, unless otherwise stated, regardless of whether "independently at each occurrence," "independently of each other," "independently of each other," or similar expressions are explicitly stated.

[0010] It should be understood that the chemical structures illustrated herein do not encompass chemical structures that would be recognized by those of ordinary skill in the art as being chemically impossible or extremely unstable.

[0011] <Oil resistant agent> The oil-proofing agent in the present disclosure provides oil resistance to a substrate (e.g., a fiber substrate, a paper substrate). The oil-proofing agent in the present disclosure may function as at least one selected from the group consisting of a repellent, a water-repellent, an oil-repellent, and a water-resistant agent, instead of or in addition to an oil-proofing agent.

[0012] Due to its structure, compound α, which is an active ingredient in the oil-resistant agent of the present disclosure, has excellent dispersibility in liquid media, and the oil-resistant agent of the present disclosure can have stable performance.

[0013] Conventional oil-proofing agents that use polymer-type compounds as active ingredients tend to have a wide molecular weight distribution and contain a relatively large amount of impurity components, whereas the active ingredient of the oil-proofing agent of the present invention is a low molecular weight agent, which can narrow (single) the molecular weight distribution and improve the performance.

[0014] The oil-resistant agent in the present disclosure includes compound α. The oil-resistant agent in the present disclosure may be compound α alone. The oil-resistant agent in the present disclosure may include other components such as a liquid medium in addition to compound α.

[0015] The oil-proofing agent in the present disclosure may not contain any selected from the group consisting of a compound having a fluoroalkyl group having 8 or more carbon atoms, a compound having a perfluoroalkyl group having 8 or more carbon atoms, a compound having a fluoroalkyl group having 4 or more carbon atoms, a compound having a perfluoroalkyl group having 4 or more carbon atoms, a compound having a perfluoroalkyl group, a compound having a fluoroalkyl group, and a compound having a fluorine atom. The oil-proofing agent in the present disclosure can impart oil resistance to a substrate even if it does not contain these fluorine compounds.

[0016] The oil-resistant agent of the present disclosure may be suitably used as a dispersion (particularly an aqueous dispersion) together with a liquid medium. The viscosity of the oil-resistant agent may be 1 cP or more, 5 cP or more, 10 cP or more, 30 cP or more, 50 cP or more, 75 cP or more, or 90 cP or more, preferably 5 cP or more, at a compound concentration of 14.8 mg / mL and 20° C. The viscosity of the oil-resistant agent may be 500 cP or less, 300 cP or less, 200 cP or less, 100 cP or less, 75 cP or less, 50 cP or less, 30 cP or less, or 20 cP or less, preferably 100 cP or less, at a compound concentration of 14.8 mg / mL and 20° C.

[0017] [Compound α] The compound α in the present disclosure is capable of adhering to a substrate and imparting liquid repellency to the substrate.

[0018] The HD (n-hexadecane) contact angle of the compound α may be 10° or more, 15° or more, 25° or more, 35° or more, 55° or more, 55° or more, or 65° or more. The HD contact angle of the compound α may be 100° or less, 90° or less, or 75° or less. When the compound α has an HD contact angle equal to or greater than the above lower limit, the substrate can be imparted with good liquid repellency (especially oil repellency). The HD contact angle is the static contact angle of the compound α with respect to the spin-coated film, and is obtained by dropping 2 μL of HD onto the spin-coated film and measuring the contact angle 1 second after the drop lands.

[0019] The water contact angle of the compound α may be 35° or more, 40° or more, 45° or more, 50° or more, 55° or more, 65° or more, 75° or more, 85° or more, 90° or more, or 100° or more. The water contact angle of the compound α may be 160° or less, 140° or less, 130° or less, 120° or less, 110° or less, 100° or less, or 90° or less. When the compound α has a water contact angle equal to or greater than the above lower limit, it can impart good liquid repellency (particularly water repellency) to the substrate. The water contact angle is the static contact angle of the compound α with respect to the spin-coated film, and is obtained by dropping 2 μL of water on the spin-coated film and measuring the contact angle 1 second after the drop lands.

[0020] The melting point of compound α may be 30° C. or higher, 40° C. or higher, 60° C. or higher, 80° C. or higher, 100° C. or higher, or 120° C. or higher, and is preferably 40° C. or higher. The melting point of compound α may be 200° C. or lower, 150° C. or lower, 100° C. or lower, or 50° C. or lower. Compound α may not have a melting point.

[0021] The molecular weight of compound α may be 200 or more, 300 or more, 500 or more, or 750 or more. The molecular weight of compound α may be 3000 or less, 2500 or less, 2000 or less, 1500 or less, 1000 or less, 750 or less, or 500 or less.

[0022] Compound α in the present disclosure may not have any group selected from the group consisting of a fluoroalkyl group having 8 or more carbon atoms, a perfluoroalkyl group having 8 or more carbon atoms, a fluoroalkyl group having 4 or more carbon atoms, a perfluoroalkyl group having 4 or more carbon atoms, a perfluoroalkyl group, a fluoroalkyl group, and a fluorine atom. Even if compound α does not contain these fluorine-containing groups, it can impart oil resistance to the substrate.

[0023] The compound α in the present disclosure may not have an active hydrogen-containing group. Examples of the active hydrogen-containing group include an amino group (an amino group not adjacent to a carbonyl group, for example, a primary amino group or a secondary amino group), a hydroxyl group, and a carboxyl group. In particular, the compound α in the present disclosure may not have a hydroxyl group from the viewpoint of oil resistance.

The treatment method may be a method in which the oil-resistant agent of the present disclosure is dispersed and diluted in an organic solvent or water as necessary, and attached to the inside and / or surface of the substrate by a known method such as dip coating, spray coating, foam coating, etc., and then dried. After drying, a textile product to which the solid components of the oil-resistant agent are attached is obtained.

[0136] The oil-resistant agent can be applied to the substrate by any of the methods known for treating substrates with liquids. The substrate may be immersed in the oil-resistant agent, or the solution may be applied or sprayed onto the substrate. The treated substrate is preferably dried and cured by heating to develop liquid repellency. The heating temperature may be, for example, 100°C to 200°C, 100°C to 170°C, or 100°C to 120°C. In the present disclosure, good performance can be obtained even with low-temperature heating (for example, 100°C to 140°C). In the present disclosure, the heating time may be 5 seconds to 60 minutes, for example, 30 seconds to 3 minutes. When the textile product is paper, the paper may be coated with the agent, or the solution may be applied or sprayed onto the paper, or the agent may be mixed with the pulp slurry before papermaking and treated. The treatment may be an external addition treatment or an internal addition treatment. Alternatively, the oil-resistant agent may be applied to the textile product by a cleaning method, for example, by washing application or dry cleaning method.

[0137] [Paper processing] Examples of the paper substrate include paper, paper containers, and paper molded articles (eg, pulp molds).

[0138] The paper can be produced by a conventional papermaking method, either an internal treatment method in which the oil-proofing agent is added to the pulp slurry before papermaking, or an external treatment method in which the oil-proofing agent is applied to the paper after papermaking.

[0139] The internal addition treatment method may mean a treatment method of adding an oil-proofing agent to a pulp slurry before papermaking. The internal addition treatment method may include, but is not limited to, one or more of the following steps: adding an oil-proofing agent to a pulp slurry and stirring and mixing it; suction-dehydrating the pulp composition prepared in the above step through a mesh body of a predetermined shape to deposit the pulp composition to form a pulp mold intermediate; and molding and drying the pulp mold intermediate with a heated mold to obtain paper, a paper container, or a paper molded article. The treated paper may be heat-treated, depending on the properties of the paper, after simple drying at room temperature or at a high temperature. The temperature of the heat treatment may be 150°C or higher, 180°C or higher, or 210°C or higher, and may be 300°C or lower, 250°C or lower, or 200°C or lower, and may be particularly 80°C to 180°C. By performing heat treatment in such a temperature range, excellent oil resistance and water resistance can be exhibited.

[0140] The size press for external additive treatment can be divided into the following types according to the coating method: One application method is a so-called pond-type two-roll size press, in which a coating liquid (size liquid) is supplied to a nip formed by passing paper between two rubber rolls, a coating liquid pool called a pond is created, and the paper is passed through this coating liquid pool to apply the size liquid to both sides of the paper. Other application methods are a gate roll type in which the size liquid is applied by a surface transfer type, and a rod metering size press. In a pond-type two-roll size press, the size liquid is likely to penetrate into the inside of the paper, and in a surface transfer type, the size liquid component is likely to remain on the surface of the paper. In the surface transfer type, the coating layer is more likely to remain on the surface of the paper than in a pond-type two-roll size press, and the coating layer formed on the surface is larger than in a pond-type two-roll size press. In the present disclosure, performance can be imparted to the paper even when the former pond-type two-roll size press is used. The paper thus treated can exhibit excellent oil resistance, water resistance, etc. by optionally accompanying a heat treatment that can take a temperature range of up to 300°C, for example up to 200°C, particularly 80°C to 180°C, depending on the properties of the paper, after simple drying at room temperature or high temperature.

Mixtures of the above pulp raw materials with synthetic fibers such as asbestos, polyamide, polyimide, polyester, polyolefin, polyvinyl alcohol, etc. may also be used.

[0143] The water resistance of paper can be improved by adding a sizing agent. Examples of the sizing agent include cationic sizing agents, anionic sizing agents, and rosin-based sizing agents (e.g., acidic rosin-based sizing agents, neutral rosin-based sizing agents). The amount of the sizing agent may be 0.01 to 5% by weight based on the pulp.

[0144] If necessary, the paper may contain additives used in the manufacture of paper, such as paper strength enhancers such as starch, modified starch, carboxymethyl cellulose, and polyamide polyamine-epichlorohydrin resin, flocculants, fixing agents, retention improvers, dyes, fluorescent dyes, slime control agents, and defoamers, to the extent that they are commonly used. It is preferable to use starch or modified starch. If necessary, oil-resistant agents may be applied to the paper using starch, polyvinyl alcohol, dyes, coating colors, anti-slip agents, etc., by a size press, gate roll coater, building blade coater, calendar, etc.

[0145] In the case of external addition, the amount of the liquid repellent compound contained in the coating layer is 0.01 to 2.0 g / m 2 , especially 0.1 to 1.0 g / m 2 The coating layer may be formed of an oil-proofing agent and starch and / or modified starch. The solid content of the oil-proofing agent for paper in the coating layer is preferably 2 g / m 2 It is preferable that: In the case of internal addition, it is preferable to mix the oil-proofing agent with the pulp so that the amount of the oil-proofing agent is 0.01 to 50 parts by weight or 0.01 to 30 parts by weight, for example 0.01 to 10 parts by weight, and particularly 0.2 to 5.0 parts by weight, per 100 parts by weight of the pulp forming the paper.

[0146] In the case of external addition, oil resistance can also be imparted to paper by using a so-called pond-type two-roll size press process in which the treatment solution is pooled between rolls and the base paper is passed through the treatment solution between the rolls at any roll speed and nip pressure.

[0147] In the external addition treatment, the paper base material may contain additives such as sizing agents, paper strength agents, flocculants, retention agents, or coagulants. The additives may be nonionic, cationic, anionic, or amphoteric. The ionic charge density of the additives may be -10000 to 10000 μeq / g, preferably -4000 to 8000 μeq / g, and more preferably -1000 to 7000 μeq / g. Additives such as sizing agents, paper strength agents, flocculants, retention agents, or coagulants (solids or active ingredients) can generally be used in an amount of 0.1 to 10% by weight (e.g., 0.2 to 5.0% by weight) based on the pulp. In the case of a paper base material containing a cationic additive (e.g., sizing agents, paper strength agents, flocculants, retention agents, or coagulants), it is preferable that the grease-resistant agent is anionic.

[0148] In the internal addition treatment, it is preferable to make a pulp slurry having a pulp concentration of 0.5 to 5.0% by weight (for example, 2.5 to 4.0% by weight).

[0149] [Pretreatment / treatment of textile products] The textile product may be pretreated before being treated with the oil-proofing agent of the present disclosure. Pretreatment of the textile product can impart excellent fastness to the textile product after treatment with the oil-proofing agent.

[0150] Examples of pretreatments of textile products include cationization treatment by reaction with a reactive quaternary ammonium salt, anionization treatment such as sulfonation, carboxylation, and phosphation, and acetylation treatment, benzoylation treatment, carboxymethylation treatment, grafting treatment, tannic acid treatment, and polymer coating treatment after anionization treatment.

[0151] The method for pretreating a textile product is not limited, and the textile product can be pretreated by a conventionally known method. The pretreatment liquid may be dispersed and diluted in an organic solvent or water as necessary, and applied to the inside and / or surface of the textile product by a known method such as dip coating, spray coating, foam coating, etc., and then dried. The pH and temperature of the pretreatment liquid may be adjusted depending on the desired degree of treatment. As an example of a method for pretreating a textile product, a method for pretreating a textile product with a hydrocarbon-based water repellent will be described in detail.

[0152] The pretreatment method for textile products is to add -SO3M to the fibers. 1 (In the formula, M 1 represents a monovalent cation), -COOM 2 (In the formula, M 2 represents a monovalent cation), and -OP(O)(OX 1 )(OX 2 )(wherein, X 1 and X 2 each independently represents a hydrogen atom or an alkyl group having 1 to 22 carbon atoms) (hereinafter, also referred to as "specific functional groups").

[0153] M 1 Examples of M include H, K, Na, and ammonium ion which may have a substituent. 2 Examples of X include H, K, Na, and ammonium ion which may have a substituent. 1 Or X 2 When is an alkyl group, it is preferably an alkyl group having 1 to 22 carbon atoms, and more preferably an alkyl group having 4 to 12 carbon atoms.

[0154] The fibers containing the specific functional groups (hereinafter, sometimes referred to as "functional group-containing fibers") can be prepared, for example, by the following method. (i) A compound having the specific functional group is attached to a fiber material. The attachment of the compound may be in a state where a part of the compound is chemically bonded to a part of the fiber to the extent that a sufficient amount of the specific functional group remains. (ii) A fiber is prepared in which the specific functional group is directly introduced into the material constituting the fiber.

[0155] In the case of (i), for example, a functional group-containing fiber can be obtained by a functional group introduction step in which a fiber material is treated with a pretreatment liquid containing one or more compounds having the specific functional group.

[0156] The oil-resistant agent can be applied to a fibrous substrate (e.g., a textile product that may have been pretreated as described above) by any of the methods known for treating textile products with liquids. When the textile product is a fabric, the fabric may be immersed in the solution or the solution may be applied or sprayed onto the fabric. The treated textile product is dried and preferably heated, for example, at 80°C to 200°C, to develop liquid repellency (water repellency and / or oil repellency). Alternatively, the oil-resistant agent may be applied to the textile product by a cleaning method, such as a washing application or a dry cleaning method.

[0157] The textile products to be treated are typically fabrics, including woven, knitted and nonwoven fabrics, clothing forms and carpets, but may also be fibers or yarns or intermediate textile products (such as slivers or rovings). The textile material may be natural fibers (such as cotton or wool), chemical fibers (such as viscose rayon or leocell), or synthetic fibers (such as polyester, polyamide or acrylic fibers), or may be a mixture of fibers (such as a mixture of natural and synthetic fibers). The method of the present disclosure also generally renders textiles hydrophobic and water repellent. Alternatively, the fibrous substrate may be leather. The manufactured polymer may be applied to the leather from an aqueous solution or emulsion at various stages of leather processing, for example during the wet processing of the leather or during the finishing of the leather, to render the leather hydrophobic and oleophobic.

[0158] "Treatment" means that the oil-resistant agent is applied to the object to be treated by immersion, spray application, etc. By the treatment, the active ingredients of the oil-resistant agent penetrate into the interior of the object to be treated and / or adhere to the surface of the object to be treated.

[0159] The material of the fiber material is not particularly limited, and examples thereof include natural fibers such as cotton, hemp, silk, wool, etc., semi-synthetic fibers such as rayon, acetate, etc., synthetic fibers such as polyamide (nylon, etc.), polyester, polyurethane, polypropylene, etc., and composite fibers, blended fibers, etc. The form of the fiber material may be any of fibers (tow, sliver, etc.), yarn, knitted fabric (including interwoven fabric), woven fabric (including interwoven fabric), nonwoven fabric, etc.

[0160] In this embodiment, from the viewpoint of improving the water repellency of the obtained textile product, it is preferable to use textile materials containing polyamide and polyester as raw materials, and in particular, it is preferable to use nylons such as nylon 6 and nylon 6,6, polyesters such as polyethylene terephthalate (PET), polytrimethyl terephthalate, and polylactic acid, and mixed fibers containing these.

[0168] As the polycarboxylic acid polymer, for example, a polymer synthesized by a conventionally known radical polymerization method using acrylic acid, methacrylic acid, maleic acid, or the like as a monomer, or a commercially available product can be used.

[0169] Examples of the method for producing a polycarboxylic acid polymer include a method in which a radical polymerization initiator is added to an aqueous solution of the above-mentioned monomer and / or its salt, and the mixture is heated and reacted at 30 to 150° C. for 2 to 5 hours. At this time, an alcohol such as methanol, ethanol, isopropyl alcohol, or an aqueous solvent such as acetone may be added to the aqueous solution of the above-mentioned monomer and / or its salt. Examples of the radical polymerization initiator include persulfates such as potassium persulfate, sodium persulfate, and ammonium persulfate, redox-based polymerization initiators such as combinations of persulfates and sodium bisulfite, hydrogen peroxide, and water-soluble azo-based polymerization initiators. These radical polymerization initiators may be used alone or in combination of two or more. Furthermore, during radical polymerization, a chain transfer agent (e.g., octyl thioglycolate) may be added for the purpose of adjusting the degree of polymerization.

[0170] In addition to the above monomers, copolymerizable monomers can be used in the radical polymerization. Examples of the copolymerizable monomers include vinyl monomers such as ethylene, vinyl chloride, and vinyl acetate, acrylamide, acrylates, and methacrylates. The acrylates and methacrylates are preferably those having a hydrocarbon group having 1 to 3 carbon atoms which may have a substituent such as a hydroxyl group. Examples of such acrylates or methacrylates include methyl acrylate, methyl methacrylate, ethyl acrylate, ethyl methacrylate, 2-hydroxyethyl acrylate, 2-hydroxyethyl methacrylate, propyl acrylate, and propyl methacrylate. These copolymerizable monomers may be used alone or in combination of two or more.

[0171] The carboxyl group in the polycarboxylic acid polymer may be free or may be neutralized with an alkali metal, an amine compound, etc. Examples of the alkali metal include sodium, potassium, and lithium, and examples of the amine compound include ammonia, monoethanolamine, diethanolamine, and triethanolamine.

[0172] The weight average molecular weight of the polycarboxylic acid polymer is preferably from 1,000 to 20,000, and more preferably from 3,000 to 15,000, from the viewpoint of improving the water repellency of the resulting textile product.

[0173] As the polycarboxylic acid polymer, commercially available products such as "Neocrystal 770" (product name, manufactured by Nicca Chemical Co., Ltd.) and "Ceropol PC-300" (product name, manufactured by Sanyo Chemical Industries, Ltd.) can be used.

[0174] Above -OP(O)(OX 1 )(OX 2 ) is exemplified by a phosphate ester compound represented by the following general formula: TIFF2025003955000015.tif3243[where, X 1 Or X 2 is the same as above, and X 3 represents an alkyl group having 1 to 22 carbon atoms.

[0175] As the phosphate ester compound, phosphate monoesters, diesters and triesters, in which the alkyl ester moiety is an alkyl group having 1 to 22 carbon atoms, and mixtures thereof can be used.

[0176] From the viewpoint of improving the water repellency of the resulting textile product, it is preferable to use lauryl phosphate and decyl phosphate.

[0177] As the phosphate ester compound, for example, a commercially available product such as "Phosphanol ML-200" (product name, manufactured by Toho Chemical Industry Co., Ltd.) can be used.

[0178] The pretreatment liquid containing one or more compounds having the specific functional group may be, for example, an aqueous solution of the above-mentioned compounds. The pretreatment liquid may also contain an acid, an alkali, a surfactant, a chelating agent, etc.

[0179] Examples of the method for treating the textile material with the pretreatment liquid include padding, immersion, spraying, and coating. Examples of padding include a method using a padding device described on pages 396-397 of Textile Dyeing and Processing Dictionary (published by Nikkan Kogyo Shimbun, 1963) and pages 256-260 of Color Dyeing Chemistry III (published by Jikkyo Publishing Co., Ltd., 1975). Examples of coating include a method using a coating machine described on pages 473-477 of Dyeing and Finishing Equipment Directory (published by Sen-sha, 1981). Examples of immersion include a method using a batch-type dyeing machine described on pages 196-247 of Dyeing and Finishing Equipment Directory (published by Sen-sha, 1981), and a liquid flow dyeing machine, air flow dyeing machine, drum dyeing machine, winch dyeing machine, washer dyeing machine, cheese dyeing machine, etc. can be used. Examples of the spray treatment include an air spray in which the treatment liquid is sprayed in the form of a mist using compressed air, and a method using an air spray of a liquid pressure atomization type. The treatment conditions, such as the concentration of the treatment liquid and the heat treatment after application, can be appropriately adjusted in consideration of various conditions such as the purpose and performance. In addition, when the pretreatment liquid contains water, it is preferable to dry the pretreatment liquid after it is applied to the fiber material in order to remove the water. There is no particular limit to the drying method, and either a dry heat method or a wet heat method may be used. There is also no particular limit to the drying temperature, and for example, drying may be performed at room temperature to 200°C for 10 seconds to several days. If necessary, heat treatment may be performed at a temperature of 100 to 180°C for about 10 seconds to 5 minutes after drying.

[0180] When the textile material is to be dyed, the treatment with the pretreatment liquid may be carried out before dyeing or in the same bath as the dyeing. However, when reduction soaping is carried out, there is a risk that the compound having the specific functional group (e.g., a phenolic polymer compound, etc.) adsorbed during the process may fall off, so it is preferable to carry out the treatment after reduction soaping after dyeing.

[0181] The treatment temperature in the immersion treatment can be 60 to 130° C. The treatment time can be 5 to 60 minutes.

[0182] In the functional group introduction step using a pretreatment liquid, the amount of the compound having the specific functional group attached is preferably 1.0 to 7.0 parts by weight per 100 parts by weight of the textile material. Within this range, durable water repellency and texture can be simultaneously achieved at high levels.

[0183] The pretreatment liquid is preferably adjusted to a pH of 3 to 5. The pH can be adjusted using a pH adjuster such as acetic acid or malic acid.

[0184] In the pretreatment solution, a salt may be used in combination in order to effectively adsorb the compound having the specific functional group to the fiber material by the salting-out effect. Examples of the salt that can be used include sodium chloride. Examples of suitable salts include sodium carbonate, ammonium sulfate, and sodium sulfate.

[0185] In the functional group introduction step using the pretreatment liquid, it is preferable to remove the compound having the specific functional group that has been treated in excess. An example of a removal method is washing with water. By removing the compound sufficiently, it is possible to prevent the development of water repellency in the subsequent water repellent treatment from being hindered, and in addition, the feel of the resulting textile product is improved. In addition, it is preferable to thoroughly dry the resulting functional group-containing fiber before contacting it with a hydrocarbon-based water repellent.

[0186] (ii) An example of a fiber in which the specific functional group is directly introduced into the material constituting the fiber is cationic dyeable polyester (CD-PET).

[0187] From the viewpoint of improving the water repellency of the resulting textile product, the functional group-containing fiber preferably has a surface zeta potential of −100 to −0.1 mV, more preferably −50 to −1 mV. The zeta potential of the fiber surface can be measured, for example, by a zeta potential / particle size measuring system ELSZ-1000ZS (manufactured by Otsuka Electronics Co., Ltd.).

[0188] Although the embodiments have been described above, it will be understood that various changes in form and details are possible without departing from the spirit and scope of the claims. EXAMPLES

[0189] The present disclosure will be described in detail below with reference to examples, but the present disclosure is not limited to these examples.

[0190] <Test Method> The test procedure is as follows.

[0191] [Preparation of treated paper] Water resistance (Cobb value) 52g / m 2 , basis weight 45g / m 2 , density 0.60g / m 3 For thin paper, 14.9mg / cm 3 The treated paper was created by applying the compound solution three times using a Baker-type applicator with a gap set to 0 mil, and then annealing at 140°C for 1 minute. Chloroform was used to adjust the coating solution. When the compound was insoluble in chloroform, organic solvents such as toluene and acetone were used.

[0192] [KIT test (oil resistance)] Measurements were made using the 3M Kit Test (TAPPI T-559cm-02). The 3M Kit Test method involves placing a test oil containing castor oil, toluene, and heptane on the surface of treated paper, wiping the test oil off after 15 seconds, and evaluating the presence or absence of oil stains on the treated paper. Tests were performed using test oils with kit numbers 1 to 6, and the highest kit number that showed no stains was used to evaluate the oil resistance.

[0193] [Corn oil resistance test (oil resistance)] Corn oil is placed on the surface of the treated paper, and after 15 seconds the test oil is wiped off. The evaluation is based on whether or not the treated paper is stained with oil. If there is no stain, mark it as a circle; if there is a stain, mark it as an X.

[0194] [HD contact angle] A solution (or dispersion) of compound α with a solid content concentration of 1.0% was spin-coated on a silicon wafer at 2500 rpm for 25 seconds to obtain a smooth spin-coated film. This was heated at 140°C for 1 minute to produce a compound-treated silicon wafer. Chloroform was used as the solvent or dispersion medium. 2 μL of HD (hexadecane) was dropped onto the compound-treated silicon wafer, and the static contact angle 1 second after the drop landed was taken as the HD contact angle of compound α.

[0195] [Water repellency test] A treatment solution containing compound α at a solid concentration of 16.8 mg / mL was prepared using chloroform as a solvent. Cloth was immersed in the treatment solution, passed through a mangle, and heat-treated to evaluate water repellency. The water repellency of the treated cloth was evaluated according to the spray method of JIS-L-1092 (AATCC-22). It is expressed by the water repellency number as shown in the table below. The higher the score, the better the water repellency. TIFF2025003955000016.tif45152

[0196] [Mold Creation] A mold was formed using an automatic molding machine. A mesh-like body was placed on a metallic pulp mold mold with many suction holes at the bottom, and a metallic tank was placed on the top, with the pulp slurry being placed in the upper metal tank. The pulp-containing aqueous composition was sucked and dehydrated through the pulp mold mold and mesh-like body at 0.1 to 1 MPa by a vacuum pump from the side opposite to the side where the mesh-like body was placed in the pulp mold mold, and the solid content (pulp, etc.) contained in the pulp-containing aqueous composition was deposited on the mesh-like body to obtain a pulp mold intermediate. Next, the obtained pulp mold intermediate was dried under a pressure of 0.1 to 1 MPa from above and below with a metallic male-female mold heated to 60 to 200°C. This produced a pulp molded product molded into the shape of a container.

[0197] [Mold test, practical oil resistance test] 100 ml of corn oil at 65°C was poured into the mold, and after leaving it at room temperature for 45 minutes, the corn oil was removed from the mold and the degree of oil staining of the mold was evaluated. The following evaluation values ​​were set according to the degree of staining. 5: No stains on the inside 4: Stain on the inside. No stain on the back. 3: Stain on the inside. Slight seepage on the back. 2: Stain on the inside. Less than 50% of the area has seeped through to the back. 1: Stain on the inside. Stain on the back is 50% or more but less than 100% of the area. 0: Seeping through to the entire back side.

[0198] [Mold test, practical water resistance test] 100 ml of water at 100°C was poured into the mold, and after leaving it at room temperature for 30 minutes, the water was removed from the mold and the degree of staining of the mold was evaluated. Depending on the degree of staining, the following evaluation values ​​were set. 5: No stains on the inside 4: Stain on the inside. No stain on the back. 3: Stain on the inside. Slight seepage on the back. 2: Stain on the inside. Less than 50% of the area has seeped through to the back. 1: Stain on the inside.
