An RI detector was used as the detector. Standard polystyrene (SRM706a NIST) was used as the standard substance. The analytical sample was prepared by recovering the polymer component by reprecipitation using IPA as a poor solvent, dissolving it in tetrahydrofuran to prepare a 0.1 wt% solution, and passing it through a 0.5 μm membrane filter. When measuring the number average molecular weight, the column was maintained at 40°C, tetrahydrofuran was used as the eluent, the flow rate was 0.35 mL / min, and 100 μL of the analytical sample was injected.
[0075] The number average molecular weight of the polymer (A) of the present disclosure can be controlled by a known method. For example, the number average molecular weight of the polymer (A) of the present disclosure can be controlled by adjusting the polymerization conditions when producing the polymer (A). Examples of the polymerization conditions include, but are not limited to, temperature, the type of initiator, the amount of initiator, the amount of monomer, and / or the presence or absence of a chain transfer agent.

Note that when the amount of repeating units derived from silicon-containing monomers is 100% by weight based on polymer (A), this means that polymer (A) is a homopolymer of the silicon-containing monomer (in other words, a homopolymer of the silicon-containing monomer).
[0077] The polymer (A) of the present disclosure may contain a monomer other than the repeating unit derived from the silicon-containing monomer. In other words, the polymer (A) of the present disclosure may be a copolymer. Such other monomer may be at least one monomer selected from the group consisting of the monomers (a) to (g) that may be contained in the vinyl polymer in the description of the compound (C) below. Detailed aspects of each of the monomers (a) to (g) are the same as those of the monomers (a) to (g) described in the description of the compound (C) below.
[0078] In one embodiment, the polymer (A) of the present disclosure may contain a repeating unit derived from a silicon-containing monomer and a repeating unit derived from a hydrocarbon group-containing monomer (a).

[0082] [Polymerization Method] The polymer (A) can be produced by a known polymerization method, and the polymerization reaction conditions can be selected arbitrarily. Examples of such polymerization methods include solution polymerization, suspension polymerization, and emulsion polymerization.
[0083] In one embodiment, polymer (A) may be obtained by copolymerizing one or more of the monomers (a) to (h) exemplified as compound (C) described in detail below with a silicon-containing monomer.
[0084] Solution polymerization involves dissolving a silicon-containing monomer in an organic solvent in the presence of a polymerization initiator, purging the atmosphere with nitrogen, and then heating and stirring for 1 to 10 hours at a temperature ranging from 30 to 120°C. 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 ranging from 0.01 to 20 parts by weight, for example, from 0.01 to 10 parts by weight, per 100 parts by weight of the monomer.
[0085] The organic solvent is inert to the silicon-containing monomer and dissolves it, and may be, for example, an ester (e.g., an ester having 2 to 40 carbon atoms, specifically, ethyl acetate or butyl acetate), a ketone (e.g., a ketone having 2 to 40 carbon atoms, specifically, methyl ethyl ketone, diisobutyl ketone, or methyl isobutyl ketone), or an alcohol (e.g., an alcohol having 1 to 40 carbon atoms, specifically, ethanol, butanol, or isopropyl alcohol). Specific examples of organic solvents include acetone, chloroform, HCFC225, isopropyl alcohol, 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 3,000 parts by weight, for example, 50 to 2,000 parts by weight, per 100 parts by weight of the total silicon-containing monomer.
[0086] In emulsion polymerization, a silicon-containing monomer is emulsified in water in the presence of a polymerization initiator and an emulsifier, and after nitrogen substitution, the mixture is heated to a predetermined temperature and stirred to polymerize.
[0087] The blending ratio of the emulsifier may be, for example, 1 part by weight or more, 3 parts by weight or more, 5 parts by weight or more, 10 parts by weight or more, 15 parts by weight or more, 20 parts by weight or more, 25 parts by weight or more, or 30 parts by weight or more, relative to 100 parts by weight of the total amount of the monomers, and may be 40 parts by weight or less, 30 parts by weight or less, 25 parts by weight or less, 20 parts by weight or less, 15 parts by weight or less, 10 parts by weight or less, or 5 parts by weight or less.
[0088] The blending ratio of water may be, for example, 50 parts by weight or more, 100 parts by weight or more, 150 parts by weight or more, or 200 parts by weight or more, and may be 400 parts by weight or less, 300 parts by weight or less, 250 parts by weight or less, or 200 parts by weight or less, relative to 100 parts by weight of the total amount of monomers.
[0089] The polymerization initiator may be a water-soluble one such as benzoyl peroxide, lauroyl peroxide, t-butyl perbenzoate, 1-hydroxycyclohexyl hydroperoxide, 3-carboxypropionyl peroxide, acetyl peroxide, azobisisobutylamidine dihydrochloride, sodium peroxide, potassium persulfate, or ammonium persulfate; or an oil-soluble one such as azobisisobutyronitrile, benzoyl peroxide, di-t-butyl peroxide, lauryl peroxide, cumene hydroperoxide, t-butyl peroxypivalate, or diisopropyl peroxydicarbonate.
[0090] The mixing ratio of the polymerization initiator may be, for example, 0.01 parts by weight or more, and 10 parts by weight or less, relative to 100 parts by weight of the monomer.
[0091] As the emulsifier, various anionic, cationic, or nonionic emulsifiers can be used, and are used in the range of 0.5 to 20 parts by weight per 100 parts by weight of the monomer. It is preferable to use an anionic and / or nonionic and / or cationic emulsifier. As the emulsifier, known emulsifiers can be used, and the dispersants exemplified as dispersants (B) described below can also be used. The emulsifiers can be used alone or in combination of two or more types.
[0092] As a method for stirring, for example, a dispersing machine such as a homomixer, an ultrasonic homogenizer, a pressure homogenizer, a milder, or a porous membrane injection dispersing machine is used, and a homomixer is preferably used. Stirring makes it easier to obtain an aqueous polymer dispersion having excellent storage stability.
[0093] Stirring conditions are appropriately set. When a homomixer is used, the rotation speed is set to, for example, 500 rpm or more and, for example, 10,000 rpm or less. The stirring time is, for example, 0.5 minutes or more and, for example, 10 minutes or less, preferably 5 minutes or less. The stirring temperature is, for example, 50°C or more and, for example, 90°C or less.
[0094] 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, to make the monomers sufficiently compatible. The addition of a compatibilizer can improve emulsifiability and copolymerizability.
[0095] The water-soluble organic solvent may be any of the organic solvents described above. Examples include acetone, methyl ethyl ketone, ethyl acetate, propylene glycol, dipropylene glycol monomethyl ether, dipropylene glycol, tripropylene glycol, and ethanol. These 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. These 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.
[0096] 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 40 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.
[0097] In the polymerization, an organic acid may be added. For example, the organic acid may be the organic acid of the present disclosure or a carboxylic acid such as acetic acid. The organic acid may be, for example, 0.01 parts by weight or more, 0.1 parts by weight or more, or 1 part by weight or less, 0.5 parts by weight or less, relative to 100 parts by weight of the total amount of the monomers.
[0098] The polymerization conditions may be such that the heating temperature is, for example, 40° C. or higher and, for example, 80° C. or lower, and the heating time is, for example, 1 hour or higher and, for example, 6 hours or lower.
[0099] The polymer (A) can be obtained through the steps including the above. In the case of emulsion polymerization, an emulsion containing the polymer (A) and the dispersant (B) can be obtained.

By containing the dispersant (B), water repellency, slip resistance, and storage stability can be favorably achieved.
[0101] The dispersant (B) may be either an organic dispersant or an inorganic dispersant, or may be a combination of an organic dispersant and an inorganic dispersant.

[0241] When the monomer (g) is used instead of the monomer (a), "100 parts by weight of the amount of repeating units derived from the monomer (a)" in the above description of the amount of each monomer may be read as "100 parts by weight of the amount of repeating units derived from the monomer (g)."
[0242] [Polymerization Method] Vinyl polymers can be produced by known polymerization methods, and the polymerization reaction conditions can be selected arbitrarily. Examples of such polymerization methods include solution polymerization, suspension polymerization, emulsion polymerization, and condensation polymerization.
[0243] In solution polymerization, a method is employed in which monomers are dissolved in an organic solvent in the presence of a polymerization initiator, and after purging with nitrogen, the mixture is heated and stirred at a temperature in the range of 30 to 120°C for 1 to 10 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 monomers.
[0244] 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 40 carbon atoms, specifically, ethyl acetate or butyl acetate), a ketone (e.g., a ketone having 2 to 40 carbon atoms, specifically, methyl ethyl ketone, diisobutyl ketone, or methyl isobutyl ketone), or an alcohol (e.g., an alcohol having 1 to 40 carbon atoms, specifically, ethanol, butanol, or isopropyl alcohol). Specific examples of the organic solvent include acetone, chloroform, HCFC225, isopropyl alcohol, 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 3,000 parts by weight, for example, 50 to 2,000 parts by weight, per 100 parts by weight of the total of the monomers.
[0245] Emulsion polymerization involves emulsifying monomers in water in the presence of a polymerization initiator and an emulsifier, purging with nitrogen, and then polymerizing the mixture at a temperature ranging from 50 to 80°C for 1 to 20 hours with stirring. Examples of polymerization initiators that can be used include water-soluble initiators such as benzoyl peroxide, lauroyl peroxide, t-butyl perbenzoate, 1-hydroxycyclohexyl hydroperoxide, 3-carboxypropionyl peroxide, acetyl peroxide, azobisisobutylamidine dihydrochloride, 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 ranging from 0.01 to 10 parts by weight per 100 parts by weight of the monomer.
[0246] 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 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 emulsification and copolymerization properties.
[0247] The water-soluble organic solvent may be any of the organic solvents described above. Examples include acetone, methyl ethyl ketone, ethyl acetate, propylene glycol, dipropylene glycol monomethyl ether, dipropylene glycol, tripropylene glycol, and ethanol. These 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. These 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.
[0248] 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 40 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.
[0249] [Isocyanate Derivative] The water repellent composition of the present disclosure may contain an isocyanate derivative, and preferably may contain an isocyanate derivative obtained by reacting an active hydrogen compound with a raw material isocyanate, which will be described below.
[0250] The isocyanate derivative is a compound obtained by reacting an active hydrogen compound with a raw material isocyanate, and has a portion derived from the active hydrogen-containing compound and a portion derived from the raw material isocyanate. Unlike isocyanate-based curing agents, the isocyanate derivative does not usually have an isocyanate group.
[0251] The isocyanate derivative has -NHCO- formed by the reaction of an active hydrogen compound with a raw material isocyanate (here, -NHCO- may be part of a urethane group or a urea group). -NHCO- is a group formed by the reaction of an active hydrogen-containing group (typically a hydroxy group) of compound (a) with an active hydrogen-reactive group (typically an isocyanate group) of compound (b). The isocyanate derivative is typically a urethane (particularly a polyurethane).
[0252] The isocyanate derivative may have a hydrocarbon group having 6 to 40 carbon atoms. The hydrocarbon group having 6 to 40 carbon atoms may be a monovalent hydrocarbon group. The hydrocarbon group may be an aromatic hydrocarbon group or an aliphatic hydrocarbon group, and is preferably an aliphatic hydrocarbon group, particularly a saturated aliphatic hydrocarbon group (alkyl group). The hydrocarbon group may be branched, cyclic, or linear, and is more preferably linear, particularly linear. The number of carbon atoms in the hydrocarbon group may be 6 or more, 8 or more, 10 or more, 12 or more, 14 or more, 16 or more, 18 or more, 20 or more, or 22 or more, preferably 10 or more, 12 or more, or 16 or more. The number of carbon atoms in the hydrocarbon group may be 40 or less, 35 or less, 30 or less, 25 or less, 20 or less, 15 or less, or 10 or less, and preferably 30 or less, 25 or less, or 20 or less.
[0253] The isocyanate derivative may have an alkyl group having 12 to 30 carbon atoms. The alkyl group having 12 to 30 carbon atoms may be branched or linear, more preferably chain-like, and particularly linear. The alkyl group contained in the isocyanate derivative may be 12 or more, 14 or more, 16 or more, 18 or more, 20 or more, or 22 or more, preferably 12 or more or 16 or more. The alkyl group contained in the isocyanate derivative may be 30 or less, 25 or less, 20 or less, 15 or less, or 10 or less, preferably 30 or less, 25 or less, or 20 or less.
[0254] The weight average molecular weight of the isocyanate derivative may be 3,000 or more, 5,000 or more, 10,000 or more, 30,000 or more, 100,000 or more, 300,000 or more, or 500,000 or more. The weight average molecular weight of the isocyanate derivative may be 1,000,000 or less, 750,000 or less, 500,000 or less, 300,000 or less, 100,000 or less, 75,000 or less, 50,000 or less, 30,000 or less, 10,000 or less, or 5,000 or less.
[0255] The water contact angle of the isocyanate derivative may be 50° or more, 55° or more, 65° or more, 75° or more, 85° or more, 90° or more, 100° or more, 105° or more, 110° or more, or 115° or more.

[0326] a is an integer of 0 or more. In terms of ease of industrial production and availability, a may be 40 or less, 30 or less, or 20 or less, and is preferably 30 or less.
[0327] The sum of a and b is 5 to 200. 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.

[0330] 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.
[0331] For example, silicones may be of the formula: (R 53 )3Si-O-[-Si(R 51 )2-O-] a -[-Si(R 51 )(R 52 )-O-] b -Si(R 53 ) 3 (S2) [wherein, 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; 52 each independently represents a long chain hydrocarbon group; 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.

[0333] 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.
[0334] Examples of silicones containing 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, with the hydrogen atoms 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 catalysts, and fatty acids are preferred as organic acids. Zinc stearate, for example, can be used. The catalyst is preferably used in an amount of 10 to 40% relative to the methylhydrogensilicone, as this enhances its effectiveness. Two or more of amino-modified silicones, epoxy-modified silicones, carboxy-modified silicones, 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.
[0335] α-olefins are compounds from which long-chain hydrocarbon groups in silicones are derived. Specific examples of α-olefins are 1-tricosene, 1-tetracosene, 1-hexacosene, 1-octacosene, 1-triacontene, and 1-dotriacontene. The hydrosilylation reaction may be carried out by reacting the α-olefin with the above-mentioned silicone having SiH groups in the presence of a catalyst, either stepwise or all at once.
[0336] The amounts of the SiH group-containing silicone and 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.
[0337] Examples of catalysts used in the hydrosilylation reaction include platinum and palladium compounds, with platinum compounds being preferred, such as platinum(IV) chloride.
[0338] 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 in an inert gas atmosphere. Examples of the inert gas include nitrogen and argon. The reaction proceeds even in the absence of a solvent, but a solvent may also be used. Examples of the solvent include dioxane, methyl isobutyl ketone, toluene, xylene, and butyl acetate.
[0339] (Reactive Silicone) The silicone may contain a reactive silicone. Examples of reactive silicones include polysiloxanes having reactive groups on the side chain, one end, both ends, or the side chain and both ends. From the viewpoint of achieving excellent slip resistance and excellent water repellency at the same time, polysiloxanes having reactive groups on 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.

These functional groups may be located on the side chains of the polysiloxane or at the terminals.
[0341] 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 a 3-glycidoxypropyl group and a 2-glycidoxyethyl group. These functional groups may be present on the side chain of the polysiloxane or at the terminal.
[0342] 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.

[0344] 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, but from the standpoint 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.

(i) The molar ratio of M units to Q units (M / Q) in a silicone resin consisting of M units and Q units is preferably M / Q = 0.6 to 1.3, more preferably M / Q = 0.8 to 1.1. Two or more of these silicone resins may be used in combination.
[0347] The silicone resin (3) may also contain a structural unit containing a hydroxyl group bonded to a silicon atom. Specifically, the structural unit may be (HO)RSiO 2/2 Units and (HO) 2 RSiO 1/2 Units: (HO)SiO 3/2 Units, (HO) 2 SiO 2/2 Units, (HO) 3 SiO 1/2 A part of the hydroxyl groups may be an alkoxy group represented by an RO group.
[0348] As described in Japanese Patent No. 3,852,921, a sol containing a silicone resin can be obtained by a production method in which an organodisiloxane, a tetraalkoxysilane, and their partial hydrolysis condensates are uniformly dispersed and polymerized in water containing a surfactant, or by a production method in which the following silane compound is hydrolyzed in water.
[0349] 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 the production, as long as the type of 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.
[0350] Conventional methods can be used to hydrolyze silane compounds in water. These methods include adding the silane compound dropwise to water while the hydrolysis reaction is carried out, or mixing water and the silane compound together and then carrying out the hydrolysis reaction. A hydrolysis catalyst may be used when carrying out the hydrolysis reaction. Conventional catalysts can be used as the hydrolysis catalyst, and acidic or alkaline catalysts are preferred. Acidic catalysts include hydrogen halides, carboxylic acids, sulfonic acids, acidic or weakly acidic inorganic salts, and solid acids such as ion exchange resins. Alkaline catalysts include 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. The amount of catalyst added is preferably adjusted so that the pH of the aqueous solution is between 2 and 7 or between 7 and 12. After the reaction is complete, a neutralizing agent may be added to neutralize the acidic or alkaline catalyst, if necessary.
[0351] 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 of two or more. Surfactants that exhibit acidic or alkaline properties can also be used as hydrolysis catalysts. The amount of surfactant added is not particularly limited, but preferably 1 to 50 parts by weight per 100 parts by weight of the silane compound. Adding less than 1 part by weight of the surfactant will not fully achieve its intended effect, while adding more than 50 parts by weight may impair the water repellency of the water repellent agent.
[0352] 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.

The emulsion containing the polymer (A) and the dispersant (B) may also be diluted with a liquid medium such as water and used as a water repellent composition.
[0392] When the polymer (A) is in a dry form (for example, powder), the water repellent composition of the present disclosure can be obtained by dispersing the dry form of the polymer (A) together with the dispersant (B) in a liquid medium.
[0393] In one embodiment, the method for producing a water repellent composition may further include a step of obtaining at least one compound (C) selected from the group consisting of a vinyl polymer, an isocyanate derivative, a wax, and a silicone, and a step of combining the polymer (A), the dispersant (B), and the compound (C).
[0394] The vinyl polymer, isocyanate derivative, wax, and silicone may be commercially available products, or may be obtained by the polymerization method described above for the compound (C).
[0395] The compound (C) in the step of obtaining the compound (C) may be in a dry form (e.g., powder) or in a state of dispersion in a liquid medium. When the compound (C) is in a state of dispersion in a dispersion, the dispersion may contain a dispersant (B).
[0396] The step of combining the polymer (A), dispersant (B), and compound (C) is not particularly limited, and may involve combining a dispersion containing the polymer (A) and dispersant (B-1) with a dispersion containing the compound (C) and dispersant (B-2). Here, the dispersants (B-1) and (B-2) are each independently dispersants selected from the dispersants (B).
[0397] A dispersion containing the polymer (A) and the dispersant (B-1) can be obtained by obtaining the polymer (A) by emulsion polymerization using the dispersant (B-1) or by dispersing the polymer (A) in a liquid medium using the dispersant (B-1). A dispersion containing the compound (C) and the dispersant (B-2) can be obtained by obtaining a vinyl polymer, silicone, or the like by emulsion polymerization using the dispersant (B-2), or by dispersing a vinyl polymer, an isocyanate derivative, a wax, or silicone in a liquid medium using the dispersant (B-2).
[0398] <Applications of Water Repellent Composition> Examples of applications of the water repellent composition according to the present disclosure include an external treatment agent (surface treatment agent) or an internal treatment agent, a water repellent composition (a water repellent, an oil repellent, or a water and oil repellent, particularly a water repellent), an antifouling agent, a soil release agent, a stripping agent, a release agent (an external release agent or an internal release agent), and the like.
[0399] <Method for Producing Treated Product> The method for producing a treated product in the present disclosure includes treating a substrate with a water repellent composition.
[0400] [Treated Products] Substrates that can be treated with the water repellent composition of the present disclosure include fibrous 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 fibrous substrates 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 thereof. Woven and knitted fabrics are described in detail below as an example of a substrate that can be treated with the water repellent composition.
[0401] (Woven and knitted fabrics) - Manufacturing method of woven and 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 performed using known looms and knitting machines, and known equipment can also be used for the preparation process prior to the weaving and knitting.
[0402] The woven or knitted fabric can be post-processed using known scouring and dyeing methods and equipment suited to the fiber material of the woven or knitted fabric.
[0403] 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 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.
[0404] The woven and knitted fabrics are suitable for use in clothing applications where water repellency is required, particularly in sportswear applications for outdoor activities, skiing, snowboarding, golf, etc., and uniform applications.
[0405] 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.
[0406] - Moisture-permeable 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.
[0407] 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.
[0408] The resin that constitutes the moisture-permeable waterproof layer is not particularly limited, but non-porous and porous resins are used. For non-porous ones, polyurethane resins and polyester elastomer resins that contain hydrophilic components are used to provide moisture permeability. For porous ones, 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.
[0409] As the polyurethane resin, a conventionally known resin obtained by reacting a polyisocyanate component with a polyol component can be used.
[0410] A moisture-permeable waterproof membrane having a microporous structure can be obtained by wet coagulation of a DMF solution of a polyurethane resin containing an 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 content of the 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.
[0411] 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.
[0412] The adhesive layer 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 terms of moisture permeability, the adhesive layer is preferably a discontinuous layer such as a dot or grid pattern.
[0413] The type of adhesive that constitutes the adhesive layer is not particularly limited, but it is preferable that it has excellent adhesion to 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.
[0414] 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.
[0415] The thickness of the adhesive layer is preferably about 10 to 100 μm, and more preferably 20 to 80 μm.
[0416] 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.
[0417] Examples of the fiber fabric for the lining include various woven fabrics, knitted fabrics, etc. Among them, knitted fabrics are preferred because, compared with woven fabrics, the constituent yarns are more likely 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 off from the moisture-permeable waterproof layer.
[0418] Furthermore, tricot knitted fabrics are also preferred in that they can be produced as long grey fabrics during knitting, have few seams, and can be evenly layered on the moisture-permeable waterproof layer.
[0419] 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.
[0420] The laminated fabric has excellent waterproof properties. A suitable example of the waterproof properties 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.
[0421] The laminated fabric has excellent moisture permeability. A preferred example of the moisture permeability of the laminated fabric of the present disclosure is a moisture permeability of, for example, 10,000 g / m2, as measured in accordance with JIS L 1099:2021 B-1 method (potassium acetate method). 2 24 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 is, 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 8000 g / m 2 24 hours or more, more preferably 10,000 g / m 224 hours or more. The upper limit of the moisture permeability is 13,000 to 15,000 g / m2, which is the limit of the measurement method. 2 ・It will take about 24 hours.
[0422] In the laminated fabric of the present disclosure, the peel strength between the woven or knitted fabric and the breathable waterproof layer, as measured in accordance with the method of JIS K 6404-2, is preferably 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.
[0423] - Manufacturing method of laminated fabric There are no particular limitations on the manufacturing method of the laminated fabric, and examples include the first manufacturing method and the second manufacturing method shown below. 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: Includes a step of forming an adhesive layer on the woven or knitted fabric or the moisture-permeable waterproof layer, and a step of bonding the woven or knitted fabric and the moisture-permeable waterproof layer via the adhesive layer.
[0424] 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.
[0425] In the second manufacturing method, examples of techniques for forming an adhesive layer on a woven or knitted fabric or a moisture-permeable waterproof layer include lamination. 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 film is then dried and heat-treated to obtain 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. Furthermore, the moisture-permeable waterproof membrane can be formed by laminating a membrane produced by a solventless extrusion method such as the T-die method or inflation method, a porous membrane produced by electrospinning, or a porous membrane made of PTFE, PE, PP, or the like.
[0426] An adhesive layer is then formed on the woven or knitted fabric or the moisture-permeable waterproof layer. For example, in the case of a method using a resin solution, a two-component curing polyurethane resin solution adjusted to 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, and the woven or knitted fabric and the moisture-permeable waterproof layer are bonded together via the adhesive layer, and the two are then pressure-bonded or thermocompression-bonded, thereby completing the second manufacturing method.
[0427] 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 second manufacturing method can then be carried out by applying the molten resin to the woven or knitted fabric or the moisture-permeable waterproof layer to form an adhesive layer, and bonding the woven or knitted fabric and the moisture-permeable waterproof layer together under pressure. 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.
[0428] Thereafter, a lining fiber fabric can be laminated on the moisture-permeable waterproof layer using any known appropriate method.
[0429] - Uses of laminated fabrics: Laminated fabrics have excellent water repellency and breathable waterproof properties, and the breathable waterproof layer does not peel off even in harsh environments, making them suitable for use in fields such as uniforms, sportswear, and outdoor products used outdoors.
[0430] [Treatment Method] The water repellent composition of the present disclosure can be applied to a substrate (particularly a fiber substrate) as a treatment agent (particularly a surface treatment agent) by a conventionally known method. The water repellent composition 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 a known method such as dip coating, spray coating, foam coating, or the like, followed by drying. After drying, a fiber product is obtained to which the solid components of the water repellent composition are attached. If necessary, the composition may be applied together with an appropriate crosslinking agent and cured. Furthermore, the water repellent composition of the present disclosure may 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 above in the "other components" section of the water repellent composition. The concentration of the hydrocarbon-based water repellent resin in the treatment agent to be brought into contact with the substrate may be varied as appropriate depending on the application, but may be 0.01 to 10% by weight, for example, 0.05 to 5% by weight.
[0431] [Textile Products] Various examples of the fiber substrate as the base material include cloth products and paper products.
[0432] Examples of textile products include natural fibers of animal or plant origin such as cotton, linen, wool, silk, etc., synthetic fibers such as polyamide, polyester (particularly polyethylene terephthalate is preferred), polyvinyl alcohol, polyacrylonitrile, polyvinyl chloride, polypropylene, etc., semi-synthetic fibers such as rayon, acetate, etc., inorganic fibers such as glass fiber, carbon fiber, asbestos fiber, etc., or mixtures of these fibers. Textile products include woven fabrics, knitted fabrics, 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 prior to being made into textiles.
[0433] 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.
[0434] The water repellent composition can be applied to a textile substrate (e.g., fabric) by any of the known methods for treating the textile substrate with a liquid. The textile substrate may be immersed in the water repellent composition, 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 and oil 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 (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.
[0435] Alternatively, the polymer may be applied to the fibrous substrate by a cleaning process, such as in a laundry application or a dry cleaning process.
[0436] The treated fiber 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 composition of the present disclosure is particularly effective in making textiles (e.g., synthetic fibers) water repellent.
[0437] 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.
[0438] Examples of natural fibers include cellulosic fibers such as cotton, flax, and 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).
[0439] 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, cupra, polynosic rayon, lyocell, and Tencel. Examples of inorganic fibers include glass fiber and carbon fiber.
[0440] 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 the wet processing of the leather or during the 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 of the paper.
[0441] The term "treatment" means applying the water repellent composition to a substrate by immersion, spraying, coating, or the like. The treatment allows the polymer (A), which is the active ingredient of the water repellent composition, 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 product) having the polymer (A) in the water repellent composition of the present disclosure adhered thereto.
[0442] [Pretreatment of Fiber Substrate] The fiber substrate may be pretreated before being treated with the water repellent composition of the present disclosure. Pretreatment of the fiber substrate can impart excellent fastness to the fiber substrate after treatment with the water repellent composition.
[0443] 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.
[0444] 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.
[0445] The pretreatment method for the fiber substrate is to add -SO 3 M 1 (In the formula, M 1represents a monovalent cation), 2 (In the formula, M 2 represents a monovalent cation), and —O—P(O)(OX 1 ) (OX 2 ) (wherein, X 1 and X 2 and 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").
[0446] 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 ammonium ions 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.
[0447] Fibers containing the specific functional groups (hereinafter sometimes referred to as "functional group-containing fibers") can be prepared, for example, by the following methods: (i) A compound having the specific functional groups is attached to a fiber material. The attachment of the compound may be in a state where a portion of the compound is chemically bonded to a portion of the fiber, to the extent that a sufficient amount of the specific functional groups remains. (ii) Fibers are prepared in which the specific functional groups are directly introduced into the material that constitutes the fiber.
[0448] 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.
[0449] The raw 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.
[0450] In this embodiment, from the viewpoint of improving the water repellency of the resulting textile product, it is preferable to use a textile material 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.

[0457] Above - COOM 2 Examples of compounds having the formula include polycarboxylic acid polymers.
[0458] 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.
[0459] 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 heating 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.
[0460] In addition to the above-mentioned monomers, copolymerizable monomers can be used for 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 of two or more.
[0461] 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.
[0462] 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.
[0463] 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.
[0464] The above -O-P(O)(OX 1 ) (OX 2 ) may be exemplified by phosphate ester compounds represented by the following general formula: [In the formula, X 1 or X 2 is as defined above, and X 3 represents an alkyl group having 1 to 22 carbon atoms.
[0465] 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.
[0466] From the viewpoint of improving the water repellency of the resulting textile product, it is preferable to use lauryl phosphate and decyl phosphate.
[0467] 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.
[0468] 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.
[0469] Methods for treating textile materials with the pretreatment liquid include, for example, padding, immersion, spraying, and coating. Examples of padding include methods using padding devices 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 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 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 treatment include air spraying, in which the treatment liquid is atomized using compressed air, and methods using a hydraulic atomization air spray. The treatment conditions, such as the concentration of the treatment liquid and the heat treatment after application, can be adjusted appropriately, taking into account various conditions, such as the purpose and performance. Furthermore, when the pretreatment liquid contains water, it is preferable to dry the pretreatment liquid after application to remove the water. The drying method is not particularly limited, and may be either a dry heat method or a wet heat method. The drying temperature is also not particularly limited, and may 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.
[0470] 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) adsorbed during the treatment may fall off, so it is preferable to carry out the treatment after reduction soaping after dyeing.
[0471] The treatment temperature in the immersion treatment can be 60 to 130° C. The treatment time can be 5 to 60 minutes.
[0472] 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.
[0473] 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.
[0474] The pretreatment solution may contain a salt to effectively adsorb the compound having the specific functional group onto the fiber material through a salting-out effect. Examples of salts that can be used include sodium chloride, sodium carbonate, ammonium sulfate, and sodium sulfate.
[0475] 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.
[0476] (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).
[0477] 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.).
[0478] The present disclosure will be described in detail below with reference to examples, but the present disclosure is not limited to these examples.
[0479] <Test Method> The test procedure is as follows.
[0480] The following instruments were used for analyzing the molecular weight: Measurement by gel permeation chromatography (GPC) (hereinafter referred to as "GPC measurement") Apparatus: HLC-8420GPC EcoSEC Elite-WS (manufactured by Tosoh Corporation) Column: TSKgel SuperMultiporeHZ-M (manufactured by Tosoh Corporation) Column temperature: 40°C Solvent: tetrahydrofuran Flow rate: 0.35 mL / min Detector: differential refractive index detector
[0481] [Water Repellency Test] The water repellency of the test cloth was evaluated according to the spray method of JIS-L-1092 (AATCC-22). The water repellency was evaluated according to the following criteria. The higher the score, the better the water repellency, and intermediate scores (95, 85, 75) were assigned depending on the condition.
[0482] 100 No wetting or water droplets were observed on the surface. 90 No wetting on the surface, but small water droplets were observed. 80 Small individual water droplets were observed on the surface. 70 Wetting was observed on half of the surface, with small individual wettings penetrating the fabric. 50 Wetting was observed on the entire surface. 0 Wetting was observed on both the front and back surfaces.
[0483] [Light Oil Repellency Test] 0.05 mL of the test liquid was dropped onto a test cloth from a height of 0.6 cm. The above procedure was repeated, with five drops dropped onto the cloth at 4.0 cm intervals. Light oil repellency was evaluated by observing the penetration and shape of the oil droplets after 30±2 seconds. The test liquid was prepared by mixing PEG-600 and oleic acid in a mass ratio of 9:1. The surface tension of this test liquid was measured using an automatic surface tensiometer DY-300 (manufactured by Kyowa Interface Science Co., Ltd.) and found to be 35.7 mN / m. Light oil repellency was evaluated according to the following criteria: A indicates the best light oil repellency, and D indicates extremely poor light oil repellency. The results of three or more of the five dropped drops were used as the evaluation value. Depending on the condition, an intermediate value (A-, B-, C+) was assigned.
[0484] A [Wetting / Penetration] Transparent (not wet) [Shape of oil droplet] Rounded B [Wetting / Penetration] Slightly darkened edges and bottom [Shape of oil droplet] Rounded C [Wetting / Penetration] Partial penetration observed [Shape of oil droplet] Contact angle 35° or less D [Wetting / Penetration] Completely penetrated [Shape of oil droplet] Flat
[0485] [Slip resistance test] The test was conducted according to ISO 13936-2 except that the load was set to 160 N, and seam slippage (mm) was measured. A smaller seam slippage value indicates better slip resistance, and a value equivalent to that of an untreated fabric, i.e., 2.0 mm or less, is most preferable.
