[0004] Patent Document 1 discloses that good chalk mark resistance can be imparted by treating a textile or other object with a composition prepared by dissolving in a solvent a silicone-containing copolymer containing structural units derived from a (meth)acrylic acid alkyl ester monomer.

[0008] <Terminology> As used herein, an "n-valent group" refers to a group having n bonds, i.e., a group that forms n bonds. An "n-valent organic group" refers to an n-valent group containing carbon, and an "organic group" refers to a group containing carbon. Such organic groups are not particularly limited, but may be hydrocarbon groups or derivatives thereof. A hydrocarbon group derivative refers to a group having one or more N, O, S, Si, amide, sulfonyl, siloxane, carbonyl, carbonyloxy, halogen, etc. at the end or molecular chain of the hydrocarbon group.
[0009] As used herein, the term "hydrocarbon group" refers to a group containing carbon and hydrogen, resulting from the elimination of a hydrogen atom from a hydrocarbon. Such hydrocarbon groups are not particularly limited, but may be C1-20 hydrocarbon groups, such as aliphatic hydrocarbon groups and aromatic hydrocarbon groups. The "aliphatic hydrocarbon group" may be linear, branched, or cyclic, and may be saturated or unsaturated. The hydrocarbon group may contain one or more ring structures. The hydrocarbon group may be substituted with one or more substituents.
[0010] In this specification, when a term (symbol) that may appear multiple times in a chemical structure is defined, that definition applies independently at 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.
[0011] The chemical structures described herein should be understood not to encompass chemical structures that would be recognized by those skilled in the art as chemically impossible or extremely unstable.
[0012] <Polymer> The polymer of the present disclosure contains a repeating unit derived from a monomer (1) represented by the following formula (1-1) or formula (1-2), and has a tackiness of 800 gf or less. R a -X-CY 3-α Z α (1-1) R a -X-NY 2-β Z β (1-2) [In each formula: R a is a polymerizable organic group, X is a single bond or a divalent group; Y's each independently represent a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms; α is an integer from 1 to 3, β is an integer of 1 or 2, Each Z is independently -Z 1 -SiZ 2 3-m Z 3 m and Z 1 is a single bond or a divalent group Z 2 are each independently a hydrocarbon group having 1 to 10 carbon atoms, m is an integer from 1 to 3, Z 3 are each independently -(O-SiZ 31 2) p -(CH2) q -Z 32 -SiZ 33 3, Z 31 are each independently a hydrocarbon group having 1 to 10 carbon atoms or -OSiZ 311 3, Z 311are each independently a hydrocarbon group having 1 to 10 carbon atoms or -OSiZ 3111 3, Z 3111 are each independently a hydrocarbon group having 1 to 10 carbon atoms, Z 32 is O or CH2, Z 33 are each independently a hydrocarbon group having 1 to 10 carbon atoms or -OSiZ 331 3, Z 331 are each independently a hydrocarbon group having 1 to 10 carbon atoms, p is an integer from 0 to 196, and q is an integer from 0 to 10.
[0013] The polymer of the present disclosure, by virtue of having the above characteristics, can impart liquid repellency (water repellency, oil repellency, oil resistance, and / or water resistance) to a substrate (e.g., a fiber substrate, a paper substrate). The polymer of the present disclosure can function as at least one selected from the group consisting of a water repellent, an oil repellent, an oil-resistant agent, and a water-resistant agent. The repellent agent of the present disclosure can effectively impart oil resistance (oil repellency) and / or water resistance (water repellency) to a substrate, and can, for example, effectively impart both oil resistance and water resistance.
[0014] The polymer of the present disclosure has the above characteristics and can impart excellent water and oil repellency to a substrate (for example, a fiber substrate or a paper substrate). The polymer of the present disclosure has the above characteristics, which may result in a low tackiness. The composition and water repellent containing the polymer of the present disclosure may also have a low tackiness. Therefore, contamination of equipment may be reduced.
[0015] [Tackiness] Tackiness is an index showing the strength of adhesive force. The larger the tackiness value, the stronger the adhesive force. The smaller the tackiness value, the weaker the adhesive force. From the viewpoint of reducing facility contamination, a smaller tackiness is preferable.
[0016] The tackiness of the polymer of the present disclosure is 800 gf or less. From the viewpoint of reducing facility contamination, the tackiness of the polymer of the present disclosure may be 700 gf or less, 600 gf or less, 500 gf or less, 450 gf or less, 400 gf or less, 350 gf or less, 300 gf or less, 250 gf or less, or 200 gf or less, preferably 600 gf or less, more preferably 300 gf or less.
[0017] The tackiness can be measured by the following method. A water repellent composition (for example, a solution or dispersion containing a polymer) was dried at 50-60°C for 2 hours, or a water repellent composition (for example, a solution or dispersion containing a polymer) was extracted with alcohol and placed on an 80mm diameter metal sample stage and heated at 40°C for 3 minutes, after which it was evaluated using a 50mm diameter probe. The tackiness was measured as the average of three measurements, or if there was variation in the measured value, five measurements were taken, the upper and lower limits were discarded, and the remaining values were averaged. The machine name and test conditions may be as follows: Machine name: RHESCA Tack Tester TAC-II type Test conditions: Constant Load (1) Immersion Speed 120 mm / min. (2) Test Speed: 600 mm / min. (3) Preload 500gf (4) Press Time 10 seconds (5) Distance 5mm The larger the measurement result, the greater the adhesiveness.
[0018] The tackiness of the polymer of the present disclosure can be controlled by adjusting the molecular structure of the polymer, the molecular weight of the polymer, and the molecular weight distribution of the polymer. The higher the molecular weight of the polymer, the easier it is to reduce the tackiness. The lower the proportion of low molecular weight polymers in the molecular weight distribution of the polymer, the easier it is to reduce the tackiness. The molecular weight and molecular weight distribution of the polymer can be controlled by known methods. For example, the molecular weight and molecular weight distribution of the polymer can be controlled by adjusting the type and amount of the initiator, using a chain transfer agent, polymerization temperature, monomer concentration, etc.
[0019] [Weight average molecular weight] The weight average molecular weight of the polymer may be 100,000 or more, 120,000 or more, 130,000 or more, 140,000 or more, 150,000 or more, or 200,000 or more. The weight average molecular weight of the polymer may be 1,000,000 or less, 750,000 or less, 500,000 or less, 400,000 or less, or 300,000 or less. [Number average molecular weight] The number average molecular weight of the polymer may be 30,000 or more, 40,000 or more, 50,000 or more, or 60,000 or more. The number average molecular weight of the polymer may be 100,000 or less, 75,000 or less, 50,000 or less, 40,000 or less, or 30,000 or less. The average molecular weight (weight average molecular weight Mw and / or number average molecular weight Mn) of the polymer of the present disclosure can be obtained by the following measurement method. Average molecular weight: The average molecular weight of the copolymer was determined by GPC (gel permeation chromatography) (in terms of polystyrene). For gel permeation chromatography, an HLC-8420GPC EcoSEC Elite-WS (manufactured by Tosoh) was used. Two TSKgel SuperMultiporeHZ-M columns were connected together. An RI detector was used. Standard polystyrene (SRM706a NIST) was used as the standard material. The analytical sample was prepared by dissolving the copolymer in tetrahydrofuran to prepare a 0.1 wt% solution and passing it through a 0.5 μm filter. When measuring the average molecular weight, the column was maintained at 40°C, tetrahydrofuran was used as the eluent, and 10 μL of the analytical sample was injected at a flow rate of 0.35 mL / min.

Therefore, the compound may be a branched hydrocarbon group (for example, a branched alkyl group), particularly a t-butyl group or an isopropyl group, a group with a multi-branched structure, or a long-chain hydrocarbon group (or a long-chain linear hydrocarbon group), such as an alkyl group.

[0237] <Method of producing polymer> The polymers of the present disclosure can be produced by any conventional polymerization method, and the polymerization reaction conditions can be selected arbitrarily. Such polymerization methods include solution polymerization, suspension polymerization, and emulsion polymerization.
[0238] In solution polymerization, a method is employed in which a monomer is dissolved in an organic solvent in the presence of a polymerization initiator, and after nitrogen substitution, the mixture is heated and stirred at a temperature in the range of 30 to 120°C for 30 minutes to 48 hours, for example, 3 to 24 hours. Examples of polymerization initiators include azobisisobutyronitrile, benzoyl peroxide, di-t-butyl peroxide, lauryl peroxide, cumene hydroperoxide, t-butyl peroxypivalate, and diisopropyl peroxydicarbonate. The polymerization initiator is used in an amount of 0.01 to 20 parts by weight, for example, 0.01 to 10 parts by weight, per 100 parts by weight of the monomer.
[0239] The organic solvent is inert to the monomers and dissolves them, and may be, for example, an ester (e.g., an ester having 2 to 30 carbon atoms, specifically, ethyl acetate, butyl acetate), a ketone (e.g., a ketone having 2 to 30 carbon atoms, specifically, methyl ethyl ketone, diisobutyl ketone), or an alcohol (e.g., an alcohol having 1 to 30 carbon atoms, specifically, isopropyl alcohol). Specific examples of the organic solvent include acetone, chloroform, HCHC225, isopropyl alcohol, pentane, hexane, heptane, octane, cyclohexane, benzene, toluene, xylene, petroleum ether, tetrahydrofuran, 1,4-dioxane, methyl ethyl ketone, methyl isobutyl ketone, diisobutyl ketone, ethyl acetate, butyl acetate, 1,1,2,2-tetrachloroethane, 1,1,1-trichloroethane, trichloroethylene, perchloroethylene, tetrachlorodifluoroethane, and trichlorotrifluoroethane. The organic solvent is used in an amount of 10 to 2000 parts by weight, for example, 50 to 1000 parts by weight, relative to 100 parts by weight of the total of the monomers.
[0240] Emulsion polymerization involves emulsifying monomers in water in the presence of a polymerization initiator and an emulsifier, purging with nitrogen, and then stirring at 50 to 80°C for 30 minutes to 48 hours, e.g., 3 to 24 hours, to polymerize. Polymerization initiators include water-soluble initiators such as benzoyl peroxide, lauroyl peroxide, t-butyl perbenzoate, 1-hydroxycyclohexyl hydroperoxide, 3-carboxypropionyl peroxide, acetyl peroxide, azobisisobutylamidine dihydrochloride, azobisisobutyronitrile, sodium peroxide, potassium persulfate, and ammonium persulfate, as well as oil-soluble initiators such as azobisisobutyronitrile, benzoyl peroxide, di-t-butyl peroxide, lauryl peroxide, cumene hydroperoxide, t-butyl peroxypivalate, and diisopropyl peroxydicarbonate. The polymerization initiator is used in an amount of 0.01 to 10 parts by weight per 100 parts by weight of monomer.
[0241] To obtain a polymer aqueous dispersion with excellent shelf stability, it is desirable to polymerize the monomer by microparticulating it in water using an emulsifying device capable of applying powerful crushing energy, such as a high-pressure homogenizer or ultrasonic homogenizer. Furthermore, various anionic, cationic, or nonionic emulsifiers can be used as emulsifiers, and are used in a range of 0.5 to 20 parts by weight per 100 parts by weight of the monomer. It is preferable to use anionic and / or nonionic and / or cationic emulsifiers. If the monomers are not completely compatible, it is preferable to add a compatibilizer, such as a water-soluble organic solvent or a low-molecular-weight monomer, that will fully compatibilize these monomers. Addition of a compatibilizer can improve emulsifiability and copolymerizability.
[0242] Examples of water-soluble organic solvents include acetone, methyl ethyl ketone, ethyl acetate, propylene glycol, dipropylene glycol monomethyl ether, dipropylene glycol, tripropylene glycol, and ethanol, which may be used in an amount of 1 to 50 parts by weight, for example, 10 to 40 parts by weight, per 100 parts by weight of water. Examples of low-molecular-weight monomers include methyl methacrylate, glycidyl methacrylate, and 2,2,2-trifluoroethyl methacrylate, which may be used in an amount of 1 to 50 parts by weight, for example, 10 to 40 parts by weight, per 100 parts by weight of the total amount of monomers.
[0243] A chain transfer agent may be used in the polymerization. The molecular weight of the polymer can be changed depending on the amount of chain transfer agent used. Examples of chain transfer agents include mercaptan group-containing compounds such as lauryl mercaptan, thioglycol, and thioglycerol (particularly alkyl mercaptans (e.g., having 1 to 30 carbon atoms)), and inorganic salts such as sodium hypophosphite and sodium hydrogen sulfite. The amount of chain transfer agent used may be in the range of 0.01 to 10 parts by weight, for example, 0.1 to 5 parts by weight, per 100 parts by weight of the total amount of monomers.
[0244] The polymer is preferably produced by emulsion polymerization or solution polymerization. After producing the polymer by polymerization, it is preferable to add water (or an aqueous medium) to disperse the polymer in water. Water (or an aqueous medium) may be added after producing the polymer by polymerization. For example, after producing a polymer by polymerizing monomers in the presence of an organic solvent, water may be added to the polymer mixture, the organic solvent may be distilled off, and the polymer may be dispersed in water. The organic solvent does not have to be distilled off. A surfactant may be added before or after polymerization, or it may not be added. A good aqueous dispersion can be obtained even when a surfactant is not added.
[0245] <Composition> The composition of the present disclosure includes the polymer of the present disclosure. The composition of the present disclosure can be obtained by combining the polymer of the present disclosure with additional components (e.g., an emulsifier, a liquid medium, a wax, etc.). The composition of the present disclosure can be obtained by polymerizing monomer (1), or monomer (1) and a hydrophobic monomer (2), in the presence of the additional components of the present disclosure (e.g., a surfactant, a liquid medium, a wax, etc.).
[0246] The composition can be an emulsion composition by including the polymer of the present disclosure, an emulsifier, and water.
[0247] [Surfactants] The composition of the present disclosure may include a surfactant as an additional component. In the composition, the surfactant may include a nonionic surfactant. Furthermore, the surfactant may include one or more surfactants selected from cationic surfactants, anionic surfactants, and amphoteric surfactants. It is preferable to use a combination of a nonionic surfactant and a cationic surfactant.

[0254] The nonionic surfactant is preferably a nonionic surfactant having an oxyalkylene group (preferably a polyoxyethylene group). The number of carbon atoms in the alkylene group in the oxyalkylene group is preferably 2 to 10. The number of oxyalkylene groups in the molecule of the nonionic surfactant is generally preferably 2 to 100. The nonionic surfactant is selected from the group consisting of ethers, esters, ester ethers, alkanolamides, polyhydric alcohols and amine oxides, and is preferably a nonionic surfactant having an oxyalkylene group.

Furthermore, the nonionic surfactant preferably has a structure that does not contain an aromatic group in view of environmental issues (biodegradability, environmental hormones, etc.).
[0256] The nonionic surfactants are those having the formula: R 1 O-(CH2CH2O) p -(R 2 O) q -R 3 [In the formula, R 1 is an alkyl group having 1 to 22 carbon atoms, or an alkenyl group or acyl group having 2 to 22 carbon atoms, R 2 are independently the same or different and are alkylene groups having 3 or more carbon atoms (e.g., 3 to 10), R 3 is a hydrogen atom, an alkyl group having 1 to 22 carbon atoms, or an alkenyl group having 2 to 22 carbon atoms, p is a number greater than or equal to 2, q is a number of 0 or 1 or more.

Examples of the alkoxy group having 1 to 40 carbon atoms include a methoxy group, an ethoxy group, a propoxy group, and a butoxy group.
[0280] The silicone may have at least one long chain hydrocarbon group. For example, R 51 At least one of R 53 At least one of or R 51 and R 53 may be a long chain hydrocarbon group, and 51At least one (for example, one) of the above may be a long-chain hydrocarbon group. Here, the long-chain hydrocarbon group may be a saturated hydrocarbon group having 6 or more, 10 or more, 15 or more, or 20 or more carbon atoms, preferably 10 or more or 23 or more carbon atoms.

[0281] The long-chain hydrocarbon group R is preferred because it is easy to produce industrially and is readily available. 51 and R 53 Other than R 51 and R 53 is preferably a hydrogen atom or a methyl group, and more preferably a methyl group.
[0282] a is an integer of equal to or greater than 0. In terms of ease of industrial production and availability, a may be equal to or less than 40, equal to or less than 30, or equal to or less than 20, and is preferably equal to or less than 30.

From the viewpoints of ease of industrial production, availability, and handling, the sum of a and b is preferably 10 to 100, and more preferably 40 to 60. a may be 0 to 150, for example, 1 to 100. The lower limit of b may be 1, 2, or 3, and the upper limit of b may be 150, 10, or 5.
[0284] When a or b is 2 or more, multiple R 51 and R 52 may be the same or different.
[0285] R51 and R 53 group (for example, when represented by the following formula (S2), R 51 and R 52 Group and R 53 It is preferred that 50 mol % or more of the total of the alkyl groups) are methyl groups.
[0286] The order of the repeating units bound by a or b is not limited to the order shown in the chemical formula, and can be any order. That is, the silicone may be a random polymer or a block polymer.
[0287] For example, silicones may have the formula: (R 53 )3Si-O-[-Si(R 51 )2-O-] a -[-Si(R 51 )(R 52 )-O-] b -Si(R 53 )3(S2) [In the formula, R 51 each independently represents a hydrogen atom, an alkyl group having 1 to 40 carbon atoms, an aryl group having 6 to 40 carbon atoms, an alkoxy group having 1 to 40 carbon atoms, or a long-chain hydrocarbon group; R 52 each independently represents a long chain hydrocarbon group; R 53 each independently represents a hydrogen atom, an alkyl group having 1 to 40 carbon atoms, an aryl group having 6 to 40 carbon atoms, an alkoxy group having 1 to 40 carbon atoms, or a long-chain hydrocarbon group; a represents an integer of 0 or more, b represents an integer of 1 or more, and (a+b) is 5 to 200.

[0288] Examples of silicones are: [ka] [In the formula, a represents an integer of 0 to 150, b represents an integer from 1 to 150; (a+b) is 5 to 200, and n is an integer of 1 to 36 (preferably n is a long-chain hydrocarbon group).
[0289] Silicone can be synthesized by a conventionally known method, for example, by subjecting silicone having a SiH group to a hydrosilylation reaction with an α-olefin.
[0290] Examples of silicones having SiH groups include methylhydrogensilicones with a degree of polymerization of 10 to 200, or copolymers of dimethylsiloxane and methylhydrogensiloxane. Among these, methylhydrogensilicones are preferred due to their ease of industrial production and availability. Hydrogensilicones (e.g., methylhydrogensilicones) are polydiorganosiloxanes in which a portion of the side chain is substituted with hydrogen, and the hydrogen atoms are directly bonded to silicon atoms. When using hydrogensilicones, a catalyst may be used to improve reactivity. For example, zinc, tin, manganese, cobalt, iron, and amine-based catalysts can be used. Metal salts of organic acids are preferred as these catalysts, and fatty acids are preferred as organic acids. From the viewpoint of easy handling, zinc stearate or the like can be used. The catalyst is preferably used in an amount of 10 to 40% relative to the methylhydrogensilicone, as this facilitates its effectiveness. Two or more of amino-modified, epoxy-modified, carboxy-modified, and methylhydrogensilicones may be mixed. All of these silicones have reactive groups, and it is preferable that they have film-forming properties. The term "film-forming ability" refers to the ability of the silicone to form a solid film, rather than an oil or gel film, after being attached to the surface of a fiber in an emulsion state.
[0291] α-olefins are compounds from which long-chain hydrocarbon groups in silicones are derived. Specific examples of α-olefins include 1-tricosene, 1-tetracosene, 1-hexacosene, 1-octacosene, 1-triacontene, and 1-dotriacontene. The hydrosilylation reaction may be carried out by reacting the above-mentioned silicone having an SiH group with an α-olefin in stages or all at once, if necessary in the presence of a catalyst.
[0292] The amounts of the SiH group-containing silicone and the α-olefin used in the hydrosilylation reaction can be appropriately selected depending on the SiH group equivalent weight or number average molecular weight of the SiH group-containing silicone.
[0293] Examples of catalysts used in the hydrosilylation reaction include platinum and palladium compounds, with platinum compounds being preferred, such as platinum(IV) chloride.
[0294] The reaction conditions for the hydrosilylation reaction are not particularly limited and can be adjusted appropriately. The reaction temperature is, for example, 10 to 200° C., preferably 50 to 150° C. The reaction time can be, for example, 3 to 12 hours when the reaction temperature is 50 to 150° C. The hydrosilylation reaction is preferably carried out under an inert gas atmosphere. Examples of inert gases include nitrogen and argon. The reaction proceeds without a solvent, but a solvent may also be used. Examples of solvents include dioxane, methyl isobutyl ketone, toluene, xylene, and butyl acetate.
[0295] (reactive silicone) The silicone may include a reactive silicone. Examples of reactive silicones include polysiloxanes having reactive groups in the side chain, one end, both ends, or the side chain and both ends. However, from the viewpoint of achieving excellent slip resistance and water repellency at the same time, polysiloxanes having reactive groups in the side chain and / or both ends may also be used. The reactive silicone is not particularly limited as long as it has a reactive group in the molecule, and examples include amino-modified silicone, epoxy-modified silicone, carboxy-modified silicone, and hydrogen-modified silicone. The reactive silicone may be one in which one or more substituents in the above formula (S1) or formula (S2) have been replaced with a reactive group.
[0296] Examples of amino-modified silicones include those having a structure in which an amino group is bonded to an organic group directly bonded to a silicon atom.

These functional groups may be located on the side chains of the polysiloxane or at the terminals.
[0297] Epoxy-modified silicones include those having a structure in which an epoxy group is bonded to an organic group directly bonded to a silicon atom. The organic group may be either an alkylene group or a divalent aromatic group. Typically, the bond between the organic group and the epoxy group is in the form of a glycidyl ether. Examples of such functional groups include 3-glycidoxypropyl and 2-glycidoxyethyl groups. These functional groups may be present on the side chain or at the terminal of the polysiloxane.
[0298] Examples of carboxy-modified silicones include those having a structure in which a carboxy group is bonded to an organic group directly bonded to a silicon atom.

The divalent aromatic group preferably has six or more carbon atoms. Examples of such functional groups include a 3-carboxypropyl group and a 2-carboxyethyl group. These functional groups may be present on the side chain of the polysiloxane or at the terminal.
[0299] (Silicone resin) The silicone may include a silicone resin. The silicone resin may be RSiO 1 / 2 Unit (M unit), RSiO 3 / 2 Units (T units) and SiO 4 / 2 The silicone resin (3) is a silicone resin consisting of at least one selected from R2SiO 2 / 2 It is preferable that the unit (D unit) is not contained in order to exert the effect of the present invention.
[0300] The silicone resin is preferably in a sol state. Examples of R include methyl, ethyl, propyl, isopropyl, butyl, isobutyl, hexyl, octyl, 2-ethylhexyl, decyl, cetyl, and stearyl groups. However, in terms of stability when the silicone resin (3) is in a sol state, ease of raw material availability, and cost, R is preferably a methyl group, and it is particularly preferred that 90% or more of all R are methyl groups. Note that different types of groups may be used in combination as R.
[0301] Silicone resin with R2SiO 2 / 2 If the silicone resin contains D units, the low slip properties of the composition may be impaired. Also, if the silicone resin contains only Q units, the water repellency of the composition may be impaired.
[0302] Examples of the silicone resin structure include (i) silicone resins consisting of M units and Q units, (ii) M units, T units and Q units, (iii) M units and T units, (iv) T units and Q units, and (v) silicone resins consisting only of T units.

[0304] As described in Patent No. 3852921, sols containing silicone resins can be obtained by a manufacturing method in which organodisiloxane, tetraalkoxysilane, and their partial hydrolysis condensates are uniformly dispersed and polymerized in water containing a surfactant, or by a manufacturing method in which the following silane compounds are hydrolyzed in water.
[0305] The production method of hydrolyzing a silane compound in water will now be described in detail. Any silane compound can be used as a raw material for production, as long as the hydrolyzable group is chloro or alkoxy, the compound contains one, three, or four hydrolyzable groups, and the compound has an alkyl group that satisfies the above conditions.Specifically, tetrachlorosilane, tetramethoxysilane, tetraethoxysilane, tetrabutoxysilane, methyltrichlorosilane, methyltrimethoxysilane, methyltriethoxysilane, methyltriisopropoxysilane, methyltributoxysilane, ethyltrichlorosilane, ethyltrimethoxysilane, ethyltriethoxysilane, propyltrichlorosilane, propyltrimethoxysilane, propyltriethoxysilane, isopropyltrichlorosilane, isopropyltrimethoxysilane, isopropyltriethoxysilane, butyltrichlorosilane, Trichlorosilane, butyltrimethoxysilane, butyltriethoxysilane, isobutyltrichlorosilane, isobutyltrimethoxysilane, isobutyltriethoxysilane, hexyltrichlorosilane, hexyltrimethoxysilane, hexyltriethoxysilane, 2-ethylhexyltrichlorosilane, 2-ethylhexyltrimethoxysilane, 2-ethylhexyltriethoxysilane, decyltrichlorosilane, decyltrimethoxysilane, decyltriethoxysilane, cetyltrichlorosilane, cetyltrimethoxysilane, cetyltriethoxy Silane, stearyl trichlorosilane, stearyl trimethoxysilane, stearyl triethoxysilane, trimethyl chlorosilane, trimethyl methoxysilane, trimethyl ethoxysilane, trimethyl isopropoxysilane, dimethyl ethyl chlorosilane, dimethyl ethyl methoxysilane, dimethyl ethyl ethoxysilane, dimethyl propyl chlorosilane, dimethyl propyl methoxysilane, dimethyl propyl ethoxysilane, dimethyl isopropyl chlorosilane, dimethyl isopropyl methoxysilane, dimethyl isopropyl ethoxysilane, di Usable silane compounds include, but are not limited to, methylhexyl chlorosilane, dimethylhexyl methoxysilane, dimethylhexyl ethoxysilane, dimethyldecyl chlorosilane, dimethyldecyl methoxysilane, dimethyldecyl ethoxysilane, dimethyl cetyl chlorosilane, dimethyl cetyl methoxysilane, dimethyl cetyl ethoxysilane, dimethylstearyl chlorosilane, dimethylstearyl methoxysilane, dimethylstearyl ethoxysilane, and partial hydrolysates thereof.From the viewpoints of operability, ease of distilling off by-products, and ease of obtaining raw materials, it is more preferable to use methoxysilane or ethoxysilane. One or a mixture of two or more of these silane compounds may be used.
[0306] As a method for hydrolyzing a silane compound in water, a commonly known common method can be used, such as a method in which the hydrolysis reaction is carried out while the silane compound is dropped into water, or a method in which water and the silane compound are mixed together and then the hydrolysis reaction is carried out. A hydrolysis catalyst may be used when carrying out the hydrolysis reaction. Conventional catalysts can be used as the hydrolysis catalyst, and it is preferable to use an acidic or alkaline catalyst. In the case of an acidic catalyst, hydrogen halide, carboxylic acid, sulfonic acid, acidic or weakly acidic inorganic salt, solid acid such as ion exchange resin is preferred. In the case of an alkaline catalyst, alkali metal salts such as sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, and sodium bicarbonate, alkali metal silanolates such as sodium silanolate and potassium silanolate, amines such as triethylamine, diethylamine, and aniline, and aqueous ammonia can be used. The amount of catalyst added is preferably adjusted so that the pH of the aqueous solution is 2 to 7 or 7 to 12. Furthermore, after completion of the reaction, a neutralizing agent to neutralize the acidic or alkaline catalyst may be added as needed.
[0307] A surfactant may be added to the aqueous solution to disperse the silane compound and the hydrolysis reaction product in water. The surfactant is not particularly limited, but examples include anionic surfactants such as alkyl sulfates, alkylbenzene sulfonates, and alkyl phosphates; nonionic surfactants such as polyoxyethylene alkyl ethers, polyoxyethylene oxypropylene alkyl ethers, polyoxyethylene alkyl phenyl ethers, and polyoxyethylene fatty acid esters; cationic surfactants such as quaternary ammonium salts and alkylamine acetates; and amphoteric surfactants such as alkyl betaines and alkyl imidazolines. These surfactants can be used alone or in combination. Surfactants that exhibit acidic or alkaline properties can also be used as hydrolysis catalysts. The amount of surfactant added is not particularly limited, but is preferably 1 to 50 parts by weight per 100 parts by weight of the silane compound. Less than 1 part by weight of the surfactant will not be effective, while more than 50 parts by weight may impair the water repellency of the water repellent agent.
[0308] A hydrolysis catalyst and surfactant may be added to a mixture of water and silane compound, if necessary, and the hydrolysis reaction may be carried out at 0 to 90°C for 10 minutes to 24 hours. A neutralization reaction may then be carried out as necessary to obtain a silicone resin. Furthermore, by-products such as alcohols and neutralized salts produced by the hydrolysis reaction may be removed by vacuum distillation or filtration. Various additives may be added to this silicone resin. For example, preservatives, thickeners, etc. may be added depending on the purpose.

[0329] [Hydrophilic particles] The composition of the present disclosure may contain hydrophilic particles as an additional component. Here, hydrophilicity refers to the property of particles easily dispersing in an aqueous solvent without agglomeration. For example, when 1.0 wt % of particle powder and an optional dispersant are added to an aqueous solvent, the mixture is stirred at 700 rpm for 10 minutes using a homomixer, and then allowed to stand for 1 hour, and no precipitation or aggregation of the particles is visually observed, the composition is considered to have hydrophilicity. Furthermore, the particles contained in commercially available aqueous particle dispersions in which particles are dispersed in an aqueous solvent are also considered to have hydrophilicity.
[0330] The hydrophilic particles may have hydrophilic groups on their surfaces. Examples of the hydrophilic groups include cationic groups, anionic groups, amino groups, and hydroxyl groups. The surfaces of the hydrophilic particles may be subjected to a hydrophilization treatment, but are generally not subjected to a hydrophobic treatment.
[0331] The hydrophilic particles are not particularly limited as long as they are hydrophilic. Examples include inorganic particles (e.g., inorganic oxide particles) such as alumina, silica, and titania, and organic particles such as latex, acrylic, and nylon. Among these, inorganic particles are preferred due to their ease of handling, and at least one selected from the group consisting of silica and alumina is particularly preferred. Examples of commercially available products include silicon oxide particles such as "Snowtex ST-OYL," "Snowtex ST-AK-L," and "Snowtex ST-AK-YL" (all manufactured by Nissan Chemical Industries Co., Ltd.), titanium oxide particles such as "TA300" and "TA300D" (both manufactured by Fuji Titanium Industry Co., Ltd.), and aluminum oxide particles such as "TM-5D" (manufactured by Taimei Chemical Industry Co., Ltd.).

A diameter within the above range ensures good water repellency. The average primary particle diameter can be measured using a microscope (scanning electron microscope or transmission electron microscope). Specifically, an arbitrary position on the fabric is observed from above using a microscope at an arbitrary magnification. Next, if the particle shape is spherical, the diameter is considered to be the particle diameter (particle size). If the particle shape is non-spherical, the average of the longest and shortest diameters is considered to be the particle size (particle size). The particle size of all particles present in the field of view is measured, and then the field of view is moved and the particle size is measured again. This process is repeated until particle sizes are measured at 10 or more points, and the average value is taken as the average primary particle size.

By being in the above range, water repellency, slip resistance, and storage stability can be excellently combined. The turbidity can be calculated based on a calibration curve (0 to 1000 ppm range) prepared using an integrating sphere turbidimeter PT200 manufactured by Nitto Seiko Analytech Co., Ltd., based on JIS K0101, Drinking Water Testing Method, using the turbidity of a standard sample, kaolin (pigment), based on the calibration curve.

The polymerization initiator is used in an amount of 0.01-10 parts by weight per 100 parts by weight of monomer.
[0353] To obtain a polymer aqueous dispersion with excellent shelf stability, it is desirable to polymerize the monomer by microparticulating it in water using an emulsifying device capable of applying powerful crushing energy, such as a high-pressure homogenizer or ultrasonic homogenizer. Furthermore, various anionic, cationic, or nonionic emulsifiers can be used as emulsifiers, and are used in an amount ranging from 0.5 to 20 parts by weight per 100 parts by weight of the monomer. It is preferable to use anionic and / or nonionic and / or cationic emulsifiers. If the monomers are not completely compatible, it is preferable to add a compatibilizer, such as a water-soluble organic solvent or a low-molecular-weight monomer, that will fully compatibilize these monomers.

The water repellent agent according to the present disclosure can impart liquid repellency to a substrate even without containing these fluorine compounds.
[0359] <Applications of water repellent agents> Examples of uses of the water repellent agent in the present disclosure include an external treatment agent (surface treatment agent) or an internal treatment agent, a repellent (a water repellent, an oil repellent, or a water and oil repellent, etc., particularly a water repellent), an antifouling agent, a stain release agent, a stripping agent, a release agent (an external release agent or an internal release agent), and the like.
[0360] <Manufacturing method of treated products> A method of making a treatment product of the present disclosure includes applying a water repellent agent of the present disclosure to a substrate.
[0361] [Processed products] Substrates that can be treated with the water repellent of the present disclosure include textile substrates, stone, filters (e.g., electrostatic filters), dust masks, fuel cell components (e.g., gas diffusion electrodes and gas diffusion supports), glass, paper, wood, leather, fur, asbestos, brick, cement, metals and oxides, ceramic products, plastics, painted surfaces, and plaster. Various examples of textile products can be mentioned. Examples include natural fibers of animal and plant origin, such as cotton, linen, wool, and silk; synthetic fibers, such as polyamide, polyester, polyvinyl alcohol, polyacrylonitrile, polyvinyl chloride, and polypropylene; semi-synthetic fibers, such as rayon and acetate; inorganic fibers, such as glass fiber, carbon fiber, and asbestos fiber; and mixtures of these fibers. As an example of a substrate that can be treated with the water repellent, woven and knitted fabrics will be described in detail below.
[0362] (woven and knitted fabrics) ·Method of manufacturing knitted fabrics Woven and knitted fabrics can be obtained by weaving and knitting long and short fiber yarns made of the above-mentioned fibers to obtain a greige fabric, which is then post-processed and subjected to a water-repellent treatment. The weaving and knitting can be carried out using known looms and knitting machines, and known equipment can also be used for the preparation process prior to the weaving and knitting.
[0363] The woven or knitted fabric can be post-processed using known scouring and dyeing methods and equipment suitable for the fiber material of the woven or knitted fabric.
[0364] After the post-processing, the woven or knitted fabric may be subjected to a water-repellent treatment. In the water-repellent treatment, first, an aqueous solution containing a water repellent (which may be the water repellent or composition of the present disclosure) is prepared. Next, the aqueous solution is applied to the woven or knitted fabric after the post-processing using a padding method, a spray method, a kiss roll coater method, a slit coater method, or the like, and then dried and subjected to a dry heat treatment. The aqueous solution may also contain a crosslinking agent, a softener, an antistatic agent, or the like, as necessary. After the water-repellent treatment, the woven or knitted fabric may be calendered to further improve the water-repellent performance.
[0365] The woven and knitted fabrics are suitable for use in clothing applications requiring water repellency, particularly sportswear applications for outdoor activities, skiing, snowboarding, golf, etc., and uniform applications.
[0366] Laminated fabric The woven / knitted fabric of the present disclosure may be provided as a laminated fabric having a moisture-permeable waterproof layer on one side thereof. The moisture-permeable waterproof layer may be laminated directly onto the woven / knitted fabric, or may be laminated onto the woven / knitted fabric via an adhesive layer. When the laminated fabric of the present disclosure is used for clothing or the like, the woven / knitted fabric side is arranged to repel rainwater and the like.
[0367] Breathable waterproof layer The moisture-permeable waterproof layer is a layer that covers one side of a woven or knitted fabric, and is a layer formed of a waterproof and moisture-permeable resin or structural film.
[0368] The moisture-permeable waterproof layer may be formed by applying a resin (the resin that constitutes the moisture-permeable waterproof layer) directly to the woven or knitted fabric, or may be laminated to one side of the woven or knitted fabric via an adhesive layer described below.
[0369] The resin constituting the moisture-permeable waterproof layer is not particularly limited, but may be: Both non-porous and porous resins are used. For non-porous materials, polyurethane resins and polyester elastomer resins containing hydrophilic components are used to provide moisture permeability. For porous materials, polyurethane resins that form wet-process porous membranes and polyurethane resins that are made porous by electrospinning are used, as well as porous PTFE membranes and porous membranes made of PE or PP.
[0370] As the polyurethane resin, a conventionally known resin obtained by reacting a polyisocyanate component with a polyol component can be used.
[0371] A moisture-permeable waterproof membrane having a microporous structure can be obtained by wet coagulation of a DMF solution of a polyurethane resin containing inorganic fine powder. Examples of inorganic fine powder include fine powders made of silicon dioxide, aluminum dioxide, or titanium dioxide. The average primary particle size of the inorganic fine powder is preferably about 7 to 40 nm. The amount of inorganic fine powder is preferably 3 to 50 wt %, and more preferably 5 to 50 wt %, of the total weight of the moisture-permeable waterproof layer.
[0372] The thickness of the moisture-permeable waterproof layer is preferably 5 μm or more, and more preferably 10 to 30 μm. A thickness within this range provides an excellent balance between waterproofness and moisture permeability, and is also advantageous in terms of texture.
[0373] ·Adhesive layer The laminated fabric preferably includes an adhesive layer. That is, the woven or knitted fabric and the moisture-permeable waterproof layer are preferably laminated via an adhesive layer. In addition, it is preferable that the adhesive layer is a discontinuous layer such as a dot or grid pattern in terms of moisture permeability.
[0374] The type of adhesive that constitutes the adhesive layer is not particularly limited, but it is preferable that it has excellent compatibility with the moisture-permeable waterproof layer. For example, if a resin containing polyurethane resin as the main component is selected as the resin that constitutes the moisture-permeable waterproof layer, it is preferable to use an adhesive layer made of a polyurethane-based adhesive. The polyurethane-based adhesive may be any of ether-based, ester-based, polycarbonate-based, etc.
[0375] The adhesive layer may be formed over the entire surface of one side of the woven or knitted fabric, or may be formed in a pattern from the viewpoint of moisture permeability, texture, etc. The pattern shape is not particularly limited, but examples include dots, lines, a grid, a checkerboard pattern, a tortoiseshell pattern, etc., and it is preferable that any of these patterns be uniformly arranged over the entire surface.
[0376] The thickness of the adhesive layer is preferably about 10 to 100 μm, and more preferably 20 to 80 μm.
[0377] Lining fabric In the laminated fabric of the present disclosure, a lining fiber fabric may be laminated on the moisture-permeable waterproof layer (on the side of the moisture-permeable waterproof layer opposite to the side on which the woven or knitted fabric of the present disclosure is laminated). The lining fiber fabric can protect the moisture-permeable waterproof layer and can provide even better waterproofness (water pressure resistance) and strength.
[0378] Examples of lining fiber fabrics include various woven and knitted fabrics. Among them, knitted fabrics are preferred because, compared with woven fabrics, the constituent yarns tend to protrude from the surface, resulting in an uneven surface, and the knitted fabric exhibits a stronger anchoring effect, making it less likely to peel from the moisture-permeable waterproof layer. Tricot knitted fabrics are also preferred because they can be knitted into long gray fabrics with few seams, allowing them to be evenly layered on the moisture-permeable waterproof layer.
[0379] The material of the fibers constituting the lining fiber fabric is not particularly limited and can be selected as appropriate, but nylon fiber is preferred. This is because acid dyes are generally used in nylon fibers, which makes it less likely for the disperse dye to migrate and sublimate into the moisture-permeable waterproof layer, a problem that occurs with polyester fibers, etc., which use disperse dyes. The form (long fiber, short fiber, or spun yarn) or fineness of the fibers constituting the lining fiber fabric are not particularly limited and can be selected as appropriate as long as the effects of the present disclosure are not impaired.
[0380] · Properties of laminated fabric The laminated fabric has excellent waterproofness. A suitable example of the waterproofness of the laminated fabric of the present disclosure is a water level measured according to the water resistance test specified in JIS L 1092:2009 Method A (low water pressure method) of 10,000 mm or more, preferably 15,000 mm or more, more preferably 16,000 mm or more, and particularly preferably 20,000 mm or more.
[0381] The laminated fabric has excellent moisture permeability. A suitable example of the moisture permeability of the laminated fabric of the present disclosure is a fabric having a moisture permeability of, for example, 10,000 g / m 2 as measured according to JIS L 1099:2021 B-1 method (potassium acetate method). 224 hours or more, preferably 15,000 g / m 2 24 hours or more, more preferably 20,000 g / m 2 The upper limit of the moisture permeability is not particularly limited, but for example, 40,000 g / m 2 24h or 35,000g / m 2 24h mm. In addition, the moisture permeability measured in accordance with JIS L 1099:2021 A-1 method (calcium chloride method) is, for example, 4000 g / m 2 24 hours or more, preferably 8000g / m 2 24 hours or more, more preferably 10,000 g / m 2 The upper limit of the moisture permeability is 13,000 to 15,000 g / m², which is the limit of the measurement method. 2 Approximately 24 hours.
[0382] In the laminated fabric of the present disclosure, the peel strength between the woven or knitted fabric and the breathable waterproof layer, as measured according to the method of JIS K 6404-2, is preferably, for example, 2.55 N / 2.54 cm or more for clothing applications, and may be preferably 5 N / 2.54 cm or more for use in applications.
[0383] ·Laminated fabric manufacturing method The method for producing the laminated fabric is not particularly limited, but examples thereof include the first and second production methods described below. First manufacturing method: The first manufacturing method includes a step of forming the moisture-permeable waterproof layer by applying a resin that constitutes the moisture-permeable waterproof layer to the surface of a woven or knitted fabric. Second manufacturing method: This method includes the steps of forming an adhesive layer on the woven or knitted fabric or the moisture-permeable waterproof layer, and bonding the woven or knitted fabric and the moisture-permeable waterproof layer together via the adhesive layer.
[0384] In the first manufacturing method, the resin that constitutes the moisture-permeable waterproof layer can be applied to the surface of the woven or knitted fabric by, for example, a coating method. A knife coater or a comma coater can be used in the coating method. From the viewpoint of providing excellent moisture permeability, it is preferable to obtain the moisture-permeable waterproof layer by a wet method.
[0385] In the second manufacturing method, examples of the method for forming an adhesive layer on a woven or knitted fabric or a moisture-permeable waterproof layer include a lamination method. In the lamination method, a resin solution or a hot melt method can be used to form the adhesive layer. First, a moisture-permeable waterproof layer-forming resin composition (e.g., a resin composition containing a resin and an organic solvent) is applied to the surface of a release material (such as release paper, release cloth, or release film) with a clearance, and a moisture-permeable waterproof layer is formed while adjusting the thickness. The layer is then dried and heat-treated to allow the reaction to complete, yielding a film. The release material can be removed as appropriate after lamination or aging. Furthermore, when laminating using a hot melt method, the release material can be peeled off and the film can be laminated alone. In addition, the breathable waterproof membrane can be bonded to membranes produced using solvent-free extrusion methods such as the T-die method and inflation, porous membranes produced using the electrospinning method, and porous membranes made of PTFE, PE, PP, etc.
[0386] An adhesive layer is then formed on the woven or knitted fabric or the moisture-permeable waterproof layer. For example, if a resin solution is used, a two-component curing polyurethane resin solution with a viscosity in the range of 500 to 5,000 mPa·s may be applied to the entire surface or in a pattern. The resulting solution is then dried to form an adhesive layer. The woven or knitted fabric and the moisture-permeable waterproof layer are then bonded together via the adhesive layer, and the two are then pressure-bonded or thermocompression-bonded to complete the second manufacturing method.
[0387] On the other hand, in the case of hot melt, it is preferable to use a moisture-curing resin that reacts with moisture in the air, and in practical use, it is more preferable to use one that melts in a temperature range of about 80 to 150°C. In this case, the hot melt resin is first melted while taking into consideration the melting point of the resin and its viscosity when melted. The molten resin is then applied to the woven or knitted fabric or the moisture-permeable waterproof layer and allowed to mature while cooling at room temperature to form an adhesive layer. The woven or knitted fabric and the moisture-permeable waterproof layer are then bonded together via the adhesive layer, thereby completing the second manufacturing method. Alternatively, if texture is important, the resin can be applied in a pattern to the moisture-permeable waterproof membrane and then bonded to the woven or knitted fabric.
[0388] Thereafter, a lining fiber fabric can be laminated on the moisture-permeable waterproof layer using any known appropriate method.
[0389] ·Applications of laminated fabric The laminated fabric has excellent water repellency and breathable waterproof properties, and the breathable waterproof layer does not peel off even in harsh environments, making it suitable for use in fields such as uniforms, sportswear, and outdoor products used outdoors.
[0390] [Processing method] The water repellent agent of the present disclosure can be applied to a substrate (particularly a fiber substrate) as a treatment agent (particularly a surface treatment agent) by conventionally known methods. The water repellent agent of the present disclosure may be dispersed and diluted in an organic solvent or water, if necessary, and applied to the surface of the substrate by known methods such as dip coating, spray coating, or foam coating, followed by drying. After drying, a fiber product is obtained with the solid components of the water repellent attached. If necessary, the water repellent agent may be applied together with an appropriate crosslinking agent and cured. Furthermore, the water repellent agent of the present disclosure can also be used in combination with various additives such as water and / or oil repellents, antislip agents, antistatic agents, texture modifiers, softeners, antibacterial agents, flame retardants, paint fixatives, wrinkle inhibitors, drying speed modifiers, crosslinking agents, film-forming aids, compatibilizers, antifreeze agents, viscosity modifiers, UV absorbers, antioxidants, pH adjusters, insect repellents, and antifoaming agents. Examples of various additives may be the same as those described in the "Other Components" section of the composition above. The concentration of the polymer in the treatment agent to be brought into contact with the substrate may be changed appropriately depending on the application, but may be 0.01 to 10% by weight, for example, 0.05 to 5% by weight.
[0391] [Textile products] Various examples of the fiber substrate as the substrate include cloth products and paper products. The fiber product as the substrate is also called a fiber substrate.
[0392] Examples of textile products include natural fibers of animal or plant origin such as cotton, linen, wool, and silk, synthetic fibers such as polyamide, polyester, polyvinyl alcohol, polyacrylonitrile, polyvinyl chloride, and polypropylene, semi-synthetic fibers such as rayon and acetate, inorganic fibers such as glass fiber, carbon fiber, and asbestos fiber, or mixtures of these fibers. Textile products include woven fabrics, knitted fabrics, and nonwoven fabrics, clothing fabrics, and carpets, but the treatment may also be applied to fibers, yarns, and intermediate textile products (for example, slivers or rovings) in a state before they are made into textiles.
[0393] Examples of paper products include paper made from bleached or unbleached chemical pulp such as kraft pulp or sulfite pulp, bleached or unbleached high-yield pulp such as groundwood pulp, mechanical pulp or thermomechanical pulp, recycled paper pulp such as recycled newspaper, recycled magazine paper, recycled corrugated cardboard or deinked recycled paper, paper containers, paper molded articles, etc. Specific examples of paper products include food packaging paper, gypsum board base paper, coated base paper, medium-quality paper, general liners and corrugating mediums, neutral white roll paper, neutral liners, rust-proof liners and metal interleaving paper, kraft paper, 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, molded paper (molded containers), etc.
[0394] The water repellent can be applied to a textile substrate (e.g., fabric) by any of the known methods for treating the substrate with a liquid. The textile substrate may be immersed in the water repellent, or the solution may be applied or sprayed onto the textile substrate. The treated textile substrate is preferably dried and cured by heating to develop water repellency. The heating temperature may be, for example, 80°C to 250°C, 100°C to 170°C, or 100°C to 120°C. The heating temperature may preferably be 100°C to 170°C. In the present disclosure, good performance can be obtained even with low-temperature heating (e.g., 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.
[0395] Alternatively, the water repellent may be applied to the textile substrate by a cleaning method, such as in a laundry application or a dry cleaning method.
[0396] The treated fibrous substrate may be a fabric, including woven fabrics, knitted fabrics, and nonwoven fabrics, clothing fabrics, carpets, etc., but may also be a fiber or yarn or intermediate fiber product (e.g., sliver or roving, etc.) The water repellent agents of the present disclosure are particularly effective in making textile products (e.g., synthetic fibers) water repellent.
[0397] The fibers constituting the fibrous substrate may be natural fibers, synthetic fibers, semi-synthetic fibers, regenerated fibers, or inorganic fibers. The fibers may be used alone or in combination of two or more types.
[0398] Examples of natural fibers include cotton, flax, cellulose fibers such as pulp, chitin, chitosan, wool, and silk. Specific examples of wood pulp include mechanical pulps such as ground wood pulp (GP), pressure-raised ground wood pulp (PGW), and thermomechanical pulp (TMP), chemical pulps such as high-yield unbleached softwood kraft pulp (HNKP; N wood), bleached softwood kraft pulp (NBKP; N wood, NB wood), unbleached hardwood kraft pulp (LUKP; L wood), and bleached hardwood kraft pulp (LBKP; L wood), recycled paper pulps such as deinking pulp (DIP) and waste pulp (WP), and semi-chemical pulp (CP).
[0399] Examples of synthetic fibers include polyesters such as polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, and copolymer polyester; polyolefins such as linear low-density polyethylene, low-density polyethylene, high-density polyethylene, and polypropylene; polyamides such as nylon 6, nylon 66, nylon 610, and nylon 46; acrylic fibers such as polyacrylonitrile; polyvinyl alcohol, polyurethane, and polyvinyl chloride. Examples of semi-synthetic fibers include acetate and triacetate. Examples of regenerated fibers include rayon, cupro, polynosic rayon, lyocell, and Tencel. Examples of inorganic fibers include glass fiber and carbon fiber.
[0400] Alternatively, the fibrous substrate may be leather. The manufacturing polymer may be applied to the leather from an aqueous solution or emulsion at various stages of leather processing, for example, during wet processing of the leather or during finishing of the leather, to render the leather hydrophobic and oleophobic. Alternatively, the fibrous substrate may be paper. The manufacturing polymer may be applied to preformed paper or may be applied at various stages of papermaking, for example, during the drying period of the paper.
[0401] "Treatment" means applying the water repellent to a substrate by immersion, spraying, coating, or the like. The treatment allows the polymer, which is the active ingredient of the water repellent, to penetrate into the substrate and / or adhere to the surface of the substrate. In other words, the treatment results in a substrate (e.g., a textile) to which the polymer in the water repellent of the present disclosure is adhered. Such a substrate is a textile having water repellency, i.e., a water-repellent textile.
[0402] [Pretreatment of fiber substrates] The fibrous substrate may be pretreated before being treated with the water repellent of the present disclosure. Pretreatment of the fibrous substrate can impart excellent durability to the fibrous substrate after treatment with the water repellent.
[0403] Examples of pretreatments of fiber substrates include cationization treatment by reaction with a reactive quaternary ammonium salt, anionization treatment such as sulfonation, carboxylation, and phosphate, acetylation treatment after anionization treatment, benzoylation treatment, carboxymethylation treatment, grafting treatment, tannic acid treatment, and polymer coating treatment.
[0404] The method for pretreating the fibrous substrate is not limited, and the fibrous substrate 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 surface of the fibrous substrate by a known method such as dip coating, spray coating, foam coating, etc., followed by drying. 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 fibrous substrate, a method for pretreating a fibrous substrate with a hydrocarbon-based water repellent will be described in detail.
[0405] The pretreatment method for the fiber substrate is to add -SO3M to the fiber. 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 2and each independently represent a hydrogen atom or an alkyl group having 1 to 22 carbon atoms) (hereinafter, also referred to as a "specific functional group").
[0406] M 1 Examples of M include H, K, Na, and ammonium ions which may have a substituent. 2 Examples of X include H, K, Na, and an 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.
[0407] 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 that constitutes the fiber.
[0408] In the case of (i), for example, functional group-containing fibers 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 above-mentioned specific functional groups.
[0409] The material of the fiber material is not particularly limited, and examples thereof include natural fibers such as cotton, linen, silk, and wool, semi-synthetic fibers such as rayon and acetate, synthetic fibers such as polyamide (nylon, etc.), polyester, polyurethane, and polypropylene, and composite fibers and blended fibers thereof. 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, paper, etc.
[0410] In this embodiment, from the viewpoint of improving the water repellency of the resulting textile product, it is preferable to use textile materials containing polyamide and polyester as raw materials, and it is particularly 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.
[0411] Above -SO3M 1 A phenolic polymer can be used as the compound having the formula:
[0033] Such a phenolic polymer can be, for example, one containing at least one compound represented by the following general formula:

[0417] Above - COOM 2 Examples of compounds having the formula include polycarboxylic acid polymers.
[0418] 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.
[0419] Examples of methods for producing polycarboxylic acid polymers include adding a radical polymerization initiator to an aqueous solution of the above-mentioned monomer and / or its salt and reacting the mixture at 30 to 150°C for 2 to 5 hours. At this time, an alcohol such as methanol, ethanol, or 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 radical polymerization initiators 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. Furthermore, during radical polymerization, a chain transfer agent (e.g., octyl thioglycolate) may be added to adjust the degree of polymerization.
[0420] In addition to the above-mentioned monomers, copolymerizable monomers can be used in radical polymerization. Examples of copolymerizable monomers include vinyl monomers such as ethylene, vinyl chloride, and vinyl acetate, acrylamide, acrylates, and methacrylates. Preferred acrylates and methacrylates have 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.
[0421] 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.
[0422] The weight average molecular weight of the polycarboxylic acid polymer is preferably from 1,000 to 20,000, more preferably from 3,000 to 15,000, from the viewpoint of improving the water repellency of the resulting textile product.
[0423] As the polycarboxylic acid polymer, commercially available products such as "Neocrystal 770" (trade name, manufactured by Nicca Chemical Co., Ltd.) and "Ceropol PC-300" (trade name, manufactured by Sanyo Chemical Industries, Ltd.) can be used.
[0424] Above -OP(O)(OX 1 )(OX 2 ) includes, for example, phosphate ester compounds represented by the following general formula: [ka] [where, X 1 or X 2 is the same as above, and X 3 represents an alkyl group having 1 to 22 carbon atoms.]
[0425] 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.
[0426] From the viewpoint of improving the water repellency of the resulting textile product, it is preferable to use lauryl phosphate and decyl phosphate.
[0427] As the phosphate ester compound, for example, commercially available products such as "Phosphanol ML-200" (trade name, manufactured by Toho Chemical Industry Co., Ltd.) can be used.
[0428] The pretreatment liquid containing one or more compounds having the specific functional group may be, for example, an aqueous solution of the compounds described above. The pretreatment liquid may also contain an acid, an alkali, a surfactant, a chelating agent, etc.
[0429] Methods for treating textile materials with the pretreatment solution include, for example, padding, immersion, spraying, and coating. Examples of padding include methods using padding devices, such as those 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 methods using coating machines, such as those described on pages 473-477 of "Dyeing and Finishing Equipment Directory" (published by Sen-sha, 1981). Examples of immersion include methods using batch dyeing machines, such as those described on pages 196-247 of "Dyeing and Finishing Equipment Directory" (published by Sen-sha, 1981). These machines include jet dyeing machines, air jet dyeing machines, drum dyeing machines, winch dyeing machines, washer dyeing machines, and cheese dyeing machines. Examples of spray treatments include air spraying, which sprays the treatment liquid in a mist form using compressed air, and methods using hydraulic atomization air spraying. The treatment conditions, such as the concentration of the treatment liquid and the heat treatment after application, can be appropriately adjusted taking into account various conditions, such as the purpose and performance. Furthermore, if the pretreatment liquid contains water, it is preferable to dry the pretreatment liquid after application to the fiber material to remove the water. The drying method is not particularly limited, and can be either a dry heat method or a wet heat method. The drying temperature is also not particularly limited, and can be, for example, drying at room temperature to 200°C for 10 seconds to several days. If necessary, heat treatment at a temperature of 100 to 180°C for 10 seconds to 5 minutes may be performed after drying.
[0430] 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 above-mentioned specific functional group (e.g., a phenolic polymer compound) adsorbed during the process may fall off, so it is preferable to carry out the treatment after reduction soaping after dyeing.
[0431] The treatment temperature in the immersion treatment can be set to 60 to 130° C. The treatment time can be set to 5 to 60 minutes.
[0432] 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 both be achieved at high levels.
[0433] The pH of the pretreatment liquid is preferably adjusted to 3 to 5. The pH can be adjusted using a pH adjuster such as acetic acid or malic acid.
[0434] The pretreatment solution may contain a salt in order to effectively adsorb the compound having the specific functional group onto the fiber material by the salting-out effect. Examples of salts that can be used include sodium chloride. Examples of suitable ammonium carbonate include sodium carbonate, sodium carbonate, ammonium sulfate, and sodium sulfate.
[0435] In the functional group introduction step using a 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 performing sufficient removal, 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. Furthermore, it is preferable to thoroughly dry the resulting functional group-containing fiber before contacting it with a hydrocarbon-based water repellent.
[0436] (ii) An example of a fiber in which the specific functional group is directly introduced into the material that constitutes the fiber is cationic dyeable polyester (CD-PET).
[0437] 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, using a zeta potential / particle size measurement system ELSZ-1000ZS (manufactured by Otsuka Electronics Co., Ltd.).
[0438] The pulp base material can be treated by an internal treatment method in which a repellent is added to pulp (e.g., pulp slurry) before papermaking, or an external treatment method in which a repellent is applied to pulp (e.g., pulp product) after papermaking. Examples of internal treatment methods include mixing and immersion, and may include a step of adding a repellent to pulp slurry and stirring and mixing. Examples of external treatment methods include spraying and application, and specific examples include pond-type two-roll size presses, gate-roll type, and rod-metering size presses. The treatment may be an external treatment or an internal treatment. For example, when the pulp base material is paper, the repellent may be coated on the paper, or the solution may be attached or sprayed on the paper, or the repellent may be mixed with the pulp slurry before papermaking.
[0439] Although the embodiments have been described above, it will be understood that various changes in form and details can be made without departing from the spirit and scope of the claims. [Example]
[0440] Examples of the present disclosure will be specifically described below, but the present disclosure is not limited to these examples.
[0441] <Test Method> The test procedure is as follows. [Molecular weight distribution] Average molecular weight: The average molecular weight of the copolymer was determined by GPC (gel permeation chromatography) (in terms of polystyrene). For gel permeation chromatography, an HLC-8420GPC EcoSEC Elite-WS (manufactured by Tosoh) was used. Two TSKgel SuperMultiporeHZ-M columns were connected together. An RI detector was used. Standard polystyrene (SRM706a NIST) was used as the standard material. The analytical sample was prepared by dissolving the copolymer in tetrahydrofuran to prepare a 0.1 wt% solution and passing it through a 0.5 μm filter. When measuring the average molecular weight, the column was maintained at 40°C, tetrahydrofuran was used as the eluent, and 10 μL of the analytical sample was injected at a flow rate of 0.35 mL / min.
[0442] [Tackiness] A solution containing the polymer was dried at 50-60°C for 2 hours, or a solution containing the polymer was extracted with alcohol, and placed on an 80mm diameter metal sample stage and heated at 40°C for 3 minutes, after which it was evaluated using a 50mm diameter probe. The tackiness was measured as the average of three measurements, or if there was variation in the measured values, five measurements were taken, the upper and lower limits were discarded, and the remaining values were averaged. Machine name: RHESCA Tack Tester TAC-II type Test conditions: Constant Load (1) Immersion Speed 120 mm / min. (2) Test Speed: 600 mm / min. (3) Preload 500gf (4) Press Time 10 seconds (5) Distance 5mm The larger the measurement result, the greater the adhesiveness.
[0443] [Water repellency] The water repellency of the treated test fabric was evaluated according to the spray method of JIS-L-1092 (AATCC-22). Water repellency was evaluated according to the following criteria. The higher the score, the better the water repellency. Depending on the condition, intermediate scores (95, 85, 75, 65, 55) were assigned. 100 No wetting or water droplets were observed on the surface. 90 The surface did not wet, but small water droplets were observed to adhere. Wetting was observed on small individual water droplets on the surface. 70 Half of the surface showed wetting, with small individual wettings observed penetrating the fabric. 50 Wetting was observed over the entire surface. 0 Wetting was observed on the entire front and back surfaces.
[0444] [Light oil repellency] The test cloth was treated with an oil blend of oleic acid and PEG at a ratio of 1:9, and the oil repellency was evaluated using the following four-point scale. Depending on the condition, an intermediate value (B+, B-, C+, C-) was assigned. A: The droplets are clear (not wet) and round. B: The edges and bottom of the droplets are slightly dark and rounded. C: Some droplets have soaked into the fabric. D: The droplet is completely saturated.
[0445] [Chalk mark resistance] Each test cloth was placed on a flat surface, and the surface of the test cloth was lightly scratched with a fingernail, and the chalk-like scratch marks left by the fingernail were visually evaluated. ◎○: The trajectory is almost invisible ○: The trajectory is barely visible ○△: The trail appears faint △: The trajectory is visible △×: The trail appears slightly dark

[0447] Si-based monomer (B) [Preparation of Monomer] (Synthesis of Intermediate 1) A four-neck flask was equipped with a thermometer, a dropping funnel, and a nitrogen line, and the flask was immersed in an ice bath. Next, 14.74 g of 1,1,1,3,3-pentamethyldisiloxane (as a siloxane compound), 0.04 g of tris(pentafluorophenyl)borane, and 30 mL of toluene were added to the flask and stirred. After creating a nitrogen atmosphere in the flask, 5.1 mL of (3-chloropropyl)diethoxy(methyl)silane (as a silane compound) and 10 mL of toluene were added to the dropping funnel, and this solution was slowly added to the flask. After the addition was complete, the ice bath was removed and stirring was continued at room temperature for 6 hours. After confirming the Si-OEt conversion by 1H-NMR, neutral alumina was added to the flask and stirred for 30 minutes. After stirring, the alumina mixture was filtered through a 0.45 μm filter to obtain a solution. The resulting solution was evaporated to dryness using a rotary evaporator, yielding Intermediate 1 as a transparent liquid. Intermediate 1 was characterized by 1H-NMR and GC. (Synthesis of Si-based monomer (B)) A four-neck flask was equipped with a thermometer, a dropping funnel, and a nitrogen line, and immersed in an ice bath. 0.01 g of butylated hydroxytoluene, 0.36 g of potassium iodide, 0.98 g of sodium acrylate, 40 mL of dimethylformamide, and 5 g of intermediate 1 were then added to the flask to obtain a mixture. After creating a nitrogen atmosphere, the flask was heated to 120 °C and the mixture was stirred for 5 hours. The flask was then cooled to 50 °C, and the mixture was washed with water using a separatory funnel to obtain a yellow liquid. This was dried over sodium sulfate, and the resulting mixture was filtered to obtain the Si-based monomer (B) as a clear liquid. The Si-based monomer (B) was characterized by 1H-NMR and GC.
