An RI detector was used. Standard polystyrene (SRM706a NIST) was used as the standard material. For the analysis sample, polymer components were recovered by reprecipitation using IPA as a poor solvent, dissolved in tetrahydrofuran to make a 0.1% by weight solution, and passed 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, and 100 μL of the analysis sample was injected at a flow rate of 0.35 mL / min.

In other words, the polymer (A) of this disclosure may be a copolymer.

[0082] [Polymerization method] Polymer (A) can be produced by known polymerization methods, and the conditions for the polymerization reaction can be arbitrarily selected. 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 monomers from monomers (a) to (h) exemplified by compound (C), which will be described in detail below, with a silicon-containing monomer.
[0084] In solution polymerization, a silicon-containing monomer is dissolved in an organic solvent in the presence of a polymerization initiator, and after nitrogen purging, the mixture is heated and stirred at a temperature 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 monomer.
[0085] Organic solvents are inert to silicon-containing monomers and dissolve them. Examples include esters (e.g., esters with 2 to 40 carbon atoms, specifically ethyl acetate and butyl acetate), ketones (e.g., ketones with 2 to 40 carbon atoms, specifically methyl ethyl ketone, diisobutyl ketone, and methyl isobutyl ketone), and alcohols (e.g., alcohols with 1 to 40 carbon atoms, specifically ethanol, butanol, and 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 3000 parts by weight, for example, 50 to 2000 parts by weight, per 100 parts by weight of the total silicon-containing monomers.
[0086] In emulsion polymerization, a method is employed in which silicon-containing monomers are emulsified in water in the presence of a polymerization initiator and an emulsifier, followed by nitrogen purging, heating to a predetermined temperature, and stirring to induce polymerization.
[0087] The proportion of emulsifier added 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, per 100 parts by weight of the total amount of monomer, or 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 proportion of water used in the mixture 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, per 100 parts by weight of the total amount of monomer, or it 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.
[0089] Polymerization initiators include water-soluble ones 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 ones such as azobisisobutyronitrile, benzoyl peroxide, di-t-butyl peroxide, lauryl peroxide, cumene hydroperoxide, t-butyl peroxypivalate, and diisopropyl peroxydicarbonate.
[0090] The proportion of polymerization initiator may be, for example, 0.01 parts by weight or more, and for example, 10 parts by weight or less, per 100 parts by weight of monomer.
[0091] Various emulsifiers, including anionic, cationic, and nonionic types, 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 monomer. It is preferable to use anionic and / or nonionic and / or cationic emulsifiers. Known emulsifiers can be used as emulsifiers, and dispersants exemplified by dispersant (B) described below can also be used. Emulsifiers can be used alone or in combination of two or more types.
[0092] As a method of stirring, dispersants such as homomixers, ultrasonic homogenizers, pressurized homogenizers, milders, and porous membrane injection dispersers can be used, and preferably a homomixer is used. Stirring makes it easier to obtain an aqueous polymer dispersion with excellent standing stability.
[0093] The stirring conditions are set as appropriate. When using a homomixer, 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 miscible, it is preferable to add a compatibilizer that makes them sufficiently miscible, such as a water-soluble organic solvent or a low molecular weight monomer. Adding a compatibilizer can improve emulsifying and copolymerizing properties.
[0095] As the water-soluble organic solvent, the organic solvents mentioned above may be used. For example, acetone, methyl ethyl ketone, ethyl acetate, propylene glycol, dipropylene glycol monomethyl ether, dipropylene glycol, tripropylene glycol, ethanol, etc., may be used in a range of 1 to 50 parts by weight, for example, 10 to 40 parts by weight, per 100 parts by weight of water. In addition, as low molecular weight monomers, methyl methacrylate, glycidyl methacrylate, 2,2,2-trifluoroethyl methacrylate, etc., may be used in a range 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] In polymerization, a chain transfer agent may be used. 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 (especially alkyl mercaptans (e.g., with 1 to 40 carbon atoms)), and inorganic salts such as sodium hypophosphite and sodium bisulfite. 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 monomer.
[0097] In polymerization, an organic acid may be added. For example, the organic acid may be an organic acid of this disclosure, or a carboxylic acid such as acetic acid. The amount of 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, or 0.5 parts by weight or less, per 100 parts by weight of the total amount of monomers.
[0098] Polymerization conditions may include a heating temperature of, for example, 40°C or higher, or 80°C or lower, and a heating time of, for example, 1 hour or more, or 6 hours or less.
[0099] By following the process described above, polymer (A) can be obtained. In the case of emulsion polymerization, an emulsion containing polymer (A) and dispersant (B) can be obtained.

[0242] [Polymerization method] Vinyl polymers can be produced by known polymerization methods, and the conditions for the polymerization reaction can be arbitrarily selected. Examples of such polymerization methods include solution polymerization, suspension polymerization, emulsion polymerization, and condensation polymerization.
[0243] In solution polymerization, monomers are dissolved in an organic solvent in the presence of a polymerization initiator, followed by nitrogen purging and heating and stirring at a temperature 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 monomer.
[0244] Organic solvents are inert to monomers and dissolve them, and may include esters (e.g., esters with 2 to 40 carbon atoms, specifically ethyl acetate and butyl acetate), ketones (e.g., ketones with 2 to 40 carbon atoms, specifically methyl ethyl ketone, diisobutyl ketone, and methyl isobutyl ketone), and alcohols (e.g., alcohols with 1 to 40 carbon atoms, specifically ethanol, butanol, and 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 3000 parts by weight, for example, 50 to 2000 parts by weight, per 100 parts by weight of the total monomers.
[0245] In emulsion polymerization, a method is employed in which monomers are emulsified in water in the presence of a polymerization initiator and an emulsifier, and then polymerized by stirring at a temperature of 50-80°C for 1-20 hours after nitrogen purging. Polymerization initiators include water-soluble ones 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 ones 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 0.01-10 parts by weight per 100 parts by weight of monomer.
[0246] To obtain a polymer aqueous dispersion with excellent stability during storage, it is desirable to polymerize the monomers by micronizing them in water using an emulsifying device that can impart strong crushing energy, such as a high-pressure homogenizer or an ultrasonic homogenizer. Various emulsifiers, including anionic, cationic, and nonionic types, can be used as emulsifiers, typically in an amount ranging from 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 miscible, it is preferable to add a compatibilizer that allows them to be sufficiently miscible, such as a water-soluble organic solvent or a low molecular weight monomer. Adding a compatibilizer can improve emulsifying and copolymerizing properties.
[0247] As the water-soluble organic solvent, the organic solvents mentioned above may be used. For example, acetone, methyl ethyl ketone, ethyl acetate, propylene glycol, dipropylene glycol monomethyl ether, dipropylene glycol, tripropylene glycol, ethanol, etc., may be used in a range of 1 to 50 parts by weight, for example, 10 to 40 parts by weight, per 100 parts by weight of water. In addition, as low molecular weight monomers, methyl methacrylate, glycidyl methacrylate, 2,2,2-trifluoroethyl methacrylate, etc., may be used in a range 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] In polymerization, a chain transfer agent may be used. 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 (especially alkyl mercaptans (e.g., with 1 to 40 carbon atoms)), and inorganic salts such as sodium hypophosphite and sodium bisulfite. 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 monomer.
[0249] [Isocyanate derivatives] The water-repellent compositions of this disclosure may contain isocyanate derivatives, and preferably may contain isocyanate derivatives obtained by the reaction of an active hydrogen compound and a raw material isocyanate as described below.
[0250] Isocyanate derivatives are compounds obtained by the reaction of an active hydrogen compound with a starting isocyanate, and have a portion derived from the active hydrogen-containing compound and a portion derived from the starting isocyanate. Unlike isocyanate-based curing agents, isocyanate derivatives do not usually have an isocyanate group.
[0251] Isocyanate derivatives have an -NHCO- group formed by the reaction of an active hydrogen compound with a starting isocyanate (where -NHCO- may be part of a urethane group or a urea group). The -NHCO- group is formed by the reaction of an active hydrogen-containing group (typically a hydroxyl group) of compound (a) with an active hydrogen-reactive group (typically an isocyanate group) of compound (b). Isocyanate derivatives are typically urethanes (especially polyurethanes).
[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 an aliphatic hydrocarbon group, particularly a saturated aliphatic hydrocarbon group (alkyl group), is preferred. The hydrocarbon group may be branched, cyclic, or linear, and 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, and 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 linear, and particularly linear. The alkyl group of the isocyanate derivative may have 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 of the isocyanate derivative may have 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 3000 or more, 5000 or more, 10000 or more, 30000 or more, 100000 or more, 300000 or more, or 500000 or more. The weight-average molecular weight of the isocyanate derivative may be 1,000000 or less, 750000 or less, 500000 or less, 300000 or less, 100000 or less, 75000 or less, 50000 or less, 30000 or less, 10000 or less, or 5000 or less.
[0255] The water contact angle of the isocyanate derivative may be 50° or higher, 55° or higher, 65° or higher, 75° or higher, 85° or higher, 90° or higher, 100° or higher, or 105° or higher, 110° or higher, or 115° or higher. The water contact angle of the isocyanate derivative may be 160° or lower, 140° or lower, 130° or lower, 120° or lower, 110° or lower, 100° or lower, or 90° or lower. By having a water contact angle of the isocyanate derivative above the lower limit, good water repellency can be imparted to the substrate. The water contact angle is the static contact angle of the isocyanate derivative with respect to the spin-coated film, and is obtained by dropping 2 μL of water onto the spin-coated film and measuring the contact angle 1 second after the drop.

[0325] In terms of being easy to manufacture industrially and readily available, the long-chain hydrocarbon group R51 and R 53 Other than R 51 and R 53 It is preferably a hydrogen atom or a methyl group, and more preferably a methyl group.
[0326] a is a non-negative integer. In terms of ease of industrial manufacture and availability, a may be 40 or less, 30 or less, or 20 or less, and preferably 30 or less.
[0327] The sum of a and b is between 5 and 200. Preferably, the sum of a and b is between 10 and 100, and more preferably between 40 and 60, in terms of ease of industrial manufacture, availability, and handling. a may be between 0 and 150, for example, 1 and 100. The lower limit of b may be 1, 2, or 3, and the upper limit of b may be 150, 10, or 5.
[0328] If a or b is 2 or more, there are multiple R 51 and R 52 Each of these may be the same or different.
[0329] R 51 and R 53 Base (for example, when expressed by the following formula (S2) R 51 and R 52 Base and R 53 It is preferable that 50 mol% or more of the total number of groups are methyl groups.
[0330] The order of existence of the repeating units enclosed by a or b is not limited to the order shown in the chemical formula, but is arbitrary. That is, the silicone may be a random polymer or a block polymer.
[0331] For example, silicone is given by 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 of these 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 of these independently represents a long-chain hydrocarbon group. R 53 Each of these 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 greater than or equal to 0, b represents an integer greater than or equal to 1, and (a+b) is between 5 and 200.

In equation (S2), R 51 and R 53 It may have an alkyl group having 3 to 40 carbon atoms or an unsaturated hydrocarbon group having 6 to 40 carbon atoms (for example, a hydrocarbon group having an aromatic ring), but it is preferable that it does not have these groups.
[0332] Examples of silicones are as follows: [ka] [In the formula, a represents an integer between 0 and 150, b represents an integer between 1 and 150. (a+b) is between 5 and 200. n is an integer between 1 and 36 (preferably n is the number of carbon atoms in the long-chain hydrocarbon group).
[0333] Silicones can be synthesized by conventionally known methods. For example, a silicone can be obtained by hydrosilylation of an α-olefin with a silicone having an SiH group.
[0334] Examples of silicones having SiH groups include methyl hydrogen silicone with a degree of polymerization of 10 to 200, or copolymers of dimethylsiloxane and methyl hydrogen siloxane. Among these, methyl hydrogen silicone is preferred because it is easy to manufacture industrially and readily available. Hydrogen silicone (e.g., methyl hydrogen silicone) is a type of polydiorganosiloxane in which part of the side chain is replaced with hydrogen, and the hydrogen atoms are directly bonded to silicon atoms. When using hydrogen silicone, a catalyst may be used to improve reactivity. For example, zinc, tin, manganese, cobalt, iron, and amine-based catalysts can be used. Organic acid metal salts are preferred as catalysts, and fatty acids are preferred as organic acids. Zinc stearate can be used, for example. It is preferable to use the catalyst at a concentration of 10 to 40% relative to the methyl hydrogen silicone, as this makes it easier to exhibit its effect. Two or more types of amino-modified silicones, epoxy-modified silicones, carboxy-modified silicones, and methyl hydrogen silicones may be mixed. All of them are silicones having reactive groups and preferably have film-forming properties. Film-forming properties refer to the ability of a silicone to form a solid film, rather than an oily or gel-like film, after being applied to the fiber surface in an emulsion state.
[0335] Alpha-olefins are compounds from which long-chain hydrocarbon groups are derived in silicones. Specific examples of alpha-olefins include 1-tricosene, 1-tetracosene, 1-hexacosene, 1-octacosene, 1-triaconthene, and 1-dotriaconthene. The hydrosilylation reaction may be carried out by reacting the α-olefin with the SiH group-containing silicone in a stepwise or one-time manner, if necessary, in the presence of a catalyst.
[0336] The amounts of SiH-containing silicone and α-olefin used in the hydrosilylation reaction can be appropriately selected depending on the SiH group equivalent or number-average molecular weight of the SiH-containing silicone.
[0337] Examples of catalysts used in hydrosilylation reactions include compounds such as platinum and palladium, with platinum compounds being preferred. Examples of platinum compounds include platinum(IV) chloride.
[0338] The reaction conditions for the hydrosilylation reaction are not particularly limited and can be adjusted as appropriate. 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. Hydrosilylation reactions are preferably carried out under an inert gas atmosphere. Examples of inert gases include nitrogen and argon. The reaction will proceed even without a solvent, but a solvent may be used. Examples of solvents include dioxane, methyl isobutyl ketone, toluene, xylene, and butyl acetate.
[0339] (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 both ends. However, from the viewpoint of having excellent slip resistance and water repellency, a polysiloxane 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 reactive groups in the molecule, but examples include amino-modified silicones, epoxy-modified silicones, carboxy-modified silicones, and hydrogen-modified silicones. The reactive silicone may be one in which one or more substituents in the above formula (S1) or formula (S2) are substituted with reactive groups.
[0340] Examples of amino-modified silicones include those having a structure in which an amino group is bonded to an organic group directly attached to a silicon atom. The organic group may be either an alkylene group or a divalent aromatic group. Alkylene groups with 2 or more carbon atoms are preferred. Divalent aromatic groups with 6 or more carbon atoms are preferred. The amino group may be a primary, secondary, or tertiary amino group. Examples of organic groups to which an amino group is bonded include: 2-aminoethyl group, N-methyl-2-aminoethyl group, N,N-dimethyl-2-aminoethyl group, N-ethyl-2-aminoethyl group, N,N-diethyl-2-aminoethyl group, N,N-methylethyl-2-aminoethyl group, 3-aminopropyl group, N-methyl-3-aminopropyl group, N,N-dimethyl-3-aminopropyl group, N-ethyl-3-aminopropyl group, N,N-diethyl-3-aminopropyl group, and N,N-methylethyl-3-aminopropyl group. These functional groups may be located on the side chains or at the terminal ends of the polysiloxane.
[0341] Examples of epoxy-modified silicones include those having a structure in which an epoxy group is bonded to an organic group directly attached to a silicon atom. The organic group may be either an alkylene group or a divalent aromatic group. Typically, the bond with the organic 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 located on the side chains or at the terminals of the polysiloxane.
[0342] Examples of carboxylated silicones include those having a structure in which a carboxyl group is bonded to an organic group directly connected to a silicon atom. The organic group may be either an alkylene group or a divalent aromatic group. Alkylene groups with two or more carbon atoms are preferred. Divalent aromatic groups with six or more carbon atoms are preferred. Examples of such functional groups include 3-carboxypropyl and 2-carboxyethyl groups. These functional groups may be located on the side chains or at the terminals of the polysiloxane.
[0343] (Silicone resin) Silicone may contain silicone resin. Silicone resin is R3SiO 1 / 2 Units (M units), RSiO 3 / 2 Units (T units) and SiO 4 / 2 A silicone resin consisting of at least one selected from units (Q units), where R is a linear or branched monovalent alkyl group having 1 to 18 carbon atoms, excluding silicone resins consisting only of M units or only of Q units). Silicone resin (3) is R2SiO 2 / 2 It is preferable to omit the units (D units) from the viewpoint of achieving the effects of this invention.
[0344] The silicone resin is preferably in a sol state. Examples of R include methyl group, ethyl group, propyl group, isopropyl group, butyl group, isobutyl group, hexyl group, octyl group, 2-ethylhexyl group, decyl group, cetyl group, stearyl group, etc. However, considering the stability, availability of raw materials, and cost when the silicone resin (3) is in a sol state, R is preferably a methyl group, and in particular, it is preferable that 90% or more of all R are methyl groups.

[0345] R2SiO in silicone resin 2 / 2 The inclusion of units (D units) may impair the low slipperiness of the water-repellent composition. Furthermore, a silicone resin consisting solely of Q units may hinder the water-repellent performance of the water-repellent composition.
[0346] Examples of silicone resin structures include (i) 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. Preferably, (i) silicone resins consisting of M units and Q units and (v) silicone resins consisting only of T units. The molar ratio (M / Q) of M units to Q units in (i) silicone resins consisting of M units and Q units is preferably M / Q = 0.6 to 1.3, and more preferably M / Q = 0.8 to 1.1. Two or more of these silicone resins may be used in combination.
[0347] Furthermore, the silicone resin (3) may contain structural units that include hydroxyl groups bonded to silicon atoms. Specifically, (HO)RSiO 2 / 2 Units, (HO)2RSiO 1 / 2 Unit: (HO)SiO 3 / 2 Unit: (HO)2SiO 2 / 2 Unit: (HO)3SiO 1 / 2 The units may be listed, and some of the hydroxyl groups may be alkoxy groups represented by RO groups.
[0348] A sol containing silicone resin can be obtained by a manufacturing method described in Patent No. 3852921, which involves uniformly dispersing and polymerizing organodisiloxane, tetraalkoxysilane and their partially hydrolyzed condensates in water containing a surfactant, or by a manufacturing method which involves hydrolyzing the silane compounds shown below in water.
[0349] This paper details a method for producing silane compounds by hydrolyzing them in water. Any silane compound can be used as a raw material for production, as long as it has one, three, or four hydrolyzable groups, and contains an alkyl group that satisfies the above conditions, and the hydrolyzable group is either chlor or alkoxy.Specifically, tetrachlorosilane, tetramethoxysilane, tetraethoxysilane, tetrabutoxysilane, methyltrichlorosilane, methyltrimethoxysilane, methyltriethoxysilane, methyltriisopropoxysilane, methyltributoxysilane, ethyltrichlorosilane, ethyltrimethoxysilane, ethyltriethoxysilane, propyltrichlorosilane, propyltrimethoxysilane, propyltriethoxysilane, isopropyltrichlorosilane, isopropyltrimethoxysilane, isopropyltriethoxysilane, butyl Lichlorosilane, butyltrimethoxysilane, butyltriethoxysilane, isobutyltrichlorosilane, isobutyltrimethoxysilane, isobutyltriethoxysilane, hexyltrichlorosilane, hexyltrimethoxysilane, hexyltriethoxysilane, 2-ethylhexyltrichlorosilane, 2-ethylhexyltrimethoxysilane, 2-ethylhexyltriethoxysilane, decyltrichlorosilane, decyltrimethoxysilane, decyltriethoxysilane, cetyltrichlorosilane, cetyltrimethoxysilane, cetyltriethoxy Silane, stearyltrichlorosilane, stearyltrimethoxysilane, stearyltriethoxysilane, trimethylchlorosilane, trimethylmethoxysilane, trimethylethoxysilane, trimethylisopropoxysilane, dimethylethylchlorosilane, dimethylethylmethoxysilane, dimethylethylethoxysilane, dimethylpropylchlorosilane, dimethylpropylmethoxysilane, dimethylpropylethoxysilane, dimethylisopropylchlorosilane, dimethylisopropylmethoxysilane, dimethylisopropylethoxysilane, dimethylisopropylethoxysilane, dimethylisopropyl methoxysilane, dimethylisopropylethoxysilane, dimethyl Methylhexylchlorsilane, dimethylhexylmethoxysilane, dimethylhexylethoxysilane, dimethyldecylchlorsilane, dimethyldecylmethoxysilane, dimethyldecylethoxysilane, dimethylcetylchlorsilane, dimethylcetylmethoxysilane, dimethylcetylethoxysilane, dimethylstearylchlorsilane, dimethylstearylmethoxysilane, dimethylstearylethoxysilane, and their partial hydrolysates are examples of usable silane compounds, but the usable silane compounds are not limited to these.Due to their ease of handling, ease of removing by-products, and availability of raw materials, methoxysilane or ethoxysilane is more preferable. One or more of these silane compounds may be used.
[0350] Common methods that are normally known can be used to hydrolyze silane compounds in water. These include methods such as adding the silane compound dropwise to water while carrying out the hydrolysis reaction, or mixing the water and silane compound together and then carrying out the hydrolysis reaction. A hydrolysis catalyst may be used when carrying out the hydrolysis reaction. Conventional known catalysts can be used as hydrolysis catalysts, and it is preferable to use acidic or alkaline catalysts. In the case of acidic catalysts, solid acids such as hydrogen halides, carboxylic acids, sulfonic acids, acidic or weakly acidic inorganic salts, and ion exchange resins are preferred. In the case of alkaline catalysts, 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. It is preferable to adjust the amount of catalyst added so that the pH of the aqueous solution is 2 to 7 and 7 to 12. After the reaction is complete, a neutralizing agent to neutralize the acidic or alkaline catalyst may be added as needed.
[0351] A surfactant may be added to the aqueous solution to disperse the silane compound and the hydrolysis reaction product in water. There are no particular restrictions on the surfactant, but for example, anionic surfactants such as alkyl sulfates, alkylbenzene sulfons, and alkyl phosphates; nonionic surfactants such as polyoxyethylene alkyl ethers, polyoxyethylene oxypropylene alkyl ethers, polyoxyethylene alkylphenyl ethers, and polyoxyethylene fatty acid esters; cationic surfactants such as quaternary ammonium salts and alkylamine acetates; and amphoteric surfactants such as alkyl betaines and alkylimidazolines can be used, either alone or in combination of two or more. Furthermore, surfactants that exhibit acidity or alkalinity can also be used as hydrolysis catalysts. There are no particular restrictions on the amount of surfactant to be added, but it is preferable to add 1 to 50 parts by weight per 100 parts by weight of the silane compound. If the amount is less than 1 part by weight, the effect of adding the surfactant will not be sufficiently obtained, and if it is more than 50 parts by weight, the water repellency of the water repellent may be impaired.
[0352] A mixture of water and a silane compound may be mixed with a hydrolysis catalyst and surfactant as needed, and the hydrolysis reaction may be carried out at 0-90°C for 10 minutes to 24 hours. Afterward, a neutralization reaction may be carried out as needed to obtain silicone resin. Alcohols and neutralization salts produced as by-products of the hydrolysis reaction can be removed by vacuum distillation or filtration. Various additives can be incorporated into this silicone resin. For example, preservatives and thickeners can be added depending on the purpose.

The emulsion containing polymer (A) and dispersant (B) may be used as is as a water-repellent composition. Alternatively, the emulsion containing polymer (A) and dispersant (B) may be diluted with a liquid medium such as water and used as a water-repellent composition.
[0392] If the polymer (A) is in the form of a dry body (e.g., a powder), the water-repellent composition of this disclosure can be obtained by dispersing the dry polymer (A) together with a dispersant (B) in a liquid medium.
[0393] In one embodiment, the method for producing a water-repellent composition is: A step of obtaining at least one compound (C) selected from the group consisting of vinyl polymers, isocyanate derivatives, waxes, and silicones, and The process may further include a step of combining a polymer (A), a dispersant (B), and a compound (C).
[0394] The vinyl polymer, isocyanate derivative, wax, and silicone may be commercially available or obtained by the polymerization method described in compound (C) above.
[0395] Compound (C) obtained in the process of obtaining compound (C) may be in the form of a dry substance (e.g., a powder) or a dispersion in a liquid medium. If compound (C) is dispersed in a dispersion, such dispersion may contain a dispersant (B).
[0396] The process of combining polymer (A), dispersant (B), and compound (C) is not particularly limited, but may involve combining a dispersion containing polymer (A) and dispersant (B-1) with a dispersion containing compound (C) and dispersant (B-2). Here, dispersant (B-1) and dispersant (B-2) are each independently selected from the above dispersant (B).
[0397] A dispersion containing polymer (A) and dispersant (B-1) can be obtained by emulsion polymerization using dispersant (B-1) to obtain polymer (A) or by dispersing polymer (A) in a liquid medium using dispersant (B-1). A dispersion containing compound (C) and dispersant (B-2) can be obtained by emulsion polymerization using dispersant (B-2) to obtain vinyl polymer, silicone, etc. or by dispersing vinyl polymer, isocyanate derivative, wax, or silicone in a liquid medium using dispersant (B-2).
[0398] <Uses of water-repellent compositions> Examples of applications for the water-repellent compositions in this disclosure include external treatment agents (surface treatment agents) or internal treatment agents, water-repellent compositions (water repellents, oil repellents or water- and oil-repellent agents, etc., especially water repellents), antifouling agents, dirt removal agents, release agents, mold release agents (external mold release agents or internal mold release agents), and the like.
[0399] <Manufacturing method for processed products> The method for manufacturing the processed product in this disclosure includes a step of treating a substrate with a water-repellent composition.
[0400] [Processed Products] Substrates that can be treated with the water-repellent composition of this disclosure include fibrous substrates, stone materials, 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 given. For example, natural animal and plant fibers such as cotton, hemp, 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 fibers, carbon fibers, and asbestos fibers; or blends thereof. An example of a substrate treated with the water-repellent composition will be described in detail regarding woven and knitted fabrics.
[0401] (Woven or knitted fabrics) • Manufacturing methods for woven and knitted fabrics Woven and knitted fabrics can be obtained by weaving and knitting long and short fibers made from the above-mentioned fibers to obtain raw fabric, and then by post-processing and water-repellent treatment. Weaving and knitting can be carried out using known looms and knitting machines, and the preparation process preceding weaving and knitting can also be carried out using known equipment.
[0402] Woven or knitted fabrics can be post-processed using known scouring and dyeing methods and equipment suitable for the fiber material of the woven or knitted fabric.
[0403] After post-processing, the woven or knitted fabric may be treated to be water-repellent. For water-repellent treatment, first, an aqueous solution containing a water-repellent agent (which may be a water-repellent agent composition as described in this disclosure) is prepared. Next, the aqueous solution is applied to the woven or knitted fabric after the post-processing using a padding method, spray method, slit coater method, etc., and after drying, it is subjected to dry heat treatment. The aqueous solution may also contain a crosslinking agent, softener, antistatic agent, etc., as needed. After water-repellent treatment, the woven or knitted fabric may be calendered.
[0404] Woven and knitted fabrics are ideally suited for clothing applications where water repellency is required, particularly for sportswear such as outdoor wear, skiing, snowboarding, and golf, as well as uniform wear.
[0405] • Laminated fabric The present disclosure may also be provided as a laminated fabric having a breathable waterproof layer on one side of the woven or knitted fabric. The breathable waterproof layer may be directly laminated to the woven or knitted fabric, or it may be laminated to the woven or knitted fabric via an adhesive layer. When the laminated fabric of the present disclosure is used for clothing or the like, the woven or knitted fabric side is positioned to repel rainwater, etc.
[0406] • Breathable waterproof layer A breathable waterproof layer is a layer that covers one side of a woven or knitted fabric, and is formed from a resin or structured film that has waterproof and breathable properties.
[0407] The breathable waterproof layer may be formed by directly applying resin (the resin constituting the breathable waterproof layer) to the woven or knitted fabric, or it may be laminated to one side of the woven or knitted fabric via an adhesive layer as described later.
[0408] The resins used to make up the breathable waterproof layer are not particularly limited, but non-porous and porous resins are used. Non-porous resins include polyurethane resins and polyester elastomer resins that have hydrophilic components to provide breathability. Porous resins include polyurethane resins that form wet porous membranes and polyurethane resins that are made porous by electrospinning, as well as porous membranes made of PTFE, PE, and PP.
[0409] As the polyurethane resin, conventionally known resins obtained by reacting a polyisocyanate component with a polyol component can be used.
[0410] A breathable waterproof membrane having a microporous structure can be obtained by a wet solidification method using a DMF solution of polyurethane resin containing inorganic fine powder. Examples of inorganic fine powders include fine powders made from 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 inorganic fine powder content is preferably 3 to 50% by weight, and more preferably 5 to 50% by weight, relative to the total amount of the moisture-permeable waterproof layer.
[0411] The thickness of the breathable waterproof layer is preferably 5 μm or more, and more preferably 10 to 30 μm. A thickness within this range provides an excellent balance of waterproofing and breathability, and also offers advantages in terms of texture.
[0412] ·Adhesive layer The laminated fabric preferably includes an adhesive layer. In other words, it is preferable that the woven or knitted fabric and the breathable waterproof layer are laminated with an adhesive layer in between. Furthermore, it is preferable for the adhesive layer to be a discontinuous layer, such as a dot or grid pattern, from the standpoint of breathability.
[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 breathable waterproof layer. For example, if a resin mainly composed of polyurethane resin is selected as the resin that constitutes the breathable waterproof layer, it is preferable to use an adhesive layer made of polyurethane adhesive. The polyurethane adhesive may be of any structure, such as ether-based, ester-based, or polycarbonate-based.
[0414] The adhesive layer may be formed over the entire surface of one side of the woven or knitted fabric, or it may be formed in a pattern from the viewpoint of breathability or texture. The pattern is not particularly limited, but examples include dots, lines, grids, checkerboard patterns, tortoiseshell patterns, etc., and it is preferable that they are uniformly arranged throughout.
[0415] The thickness of the adhesive layer is preferably about 10 to 100 μm, and more preferably 20 to 80 μm.
[0416] • Lining fabric In the laminated fabric of this disclosure, a lining fabric may be laminated on the breathable waterproof layer (on the side of the breathable waterproof layer opposite to the side on which the woven or knitted fabric of this disclosure is laminated). The lining fabric can protect the breathable waterproof layer, and the waterproofness (water pressure resistance) and strength can be further improved.
[0417] Examples of lining fabrics include various woven and knitted fabrics. Among these, knitted fabrics are preferable because, compared to woven fabrics, the constituent threads tend to protrude more easily from the surface, resulting in a less flat surface. This allows for a greater anchoring effect, making it less likely to separate from the breathable waterproof layer.
[0418] Furthermore, tricot knit fabric is preferable because it allows for the production of long lengths of raw material during the knitting process, resulting in fewer seams and enabling uniform lamination on a breathable waterproof layer.
[0419] The material of the fibers constituting the lining fabric is not particularly limited and can be selected as appropriate, but nylon fibers are preferred. This is because, since acid dyes are generally used for nylon fibers, the migration and sublimation of disperse dyes to the breathable waterproof layer, which is a problem with polyester fibers and the like that use disperse dyes, is less likely to occur. The form of the constituent fibers of the lining fabric (long fibers, short fibers, or spun yarn) or the fineness is not particularly limited and can be selected as appropriate within a range that does not impair the effects of this disclosure.
[0420] • Characteristics of laminated fabric Laminated fabrics have excellent waterproofing properties. A good example of the waterproofing properties of the laminated fabrics of this disclosure is a water level measured according to the water resistance test specified in JIS L 1092:2009 Method A (low water pressure method), which is, for example, 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] Laminated fabrics have excellent moisture permeability. A preferred example of the moisture permeability of the laminated fabrics of this disclosure is a moisture permeability of, for example, 10,000 g / m² as measured according to the JIS L 1099:2021 B-1 method (potassium acetate method). 224 hours or more, preferably 15,000 g / m² 2 24 hours or more, more preferably 20,000 g / m² 2 • 24 hours or more is a possible example. There are no particular restrictions on the upper limit of this moisture permeability, but for example, 40,000 g / m 2 24h or 35,000g / m² 2 One example is 24h·mm. Additionally, the moisture permeability measured according to JIS L 1099:2021 A-1 method (calcium chloride method) is, for example, 4000g / m³. 2 24 hours or more, preferably 8000 g / m² 2 24 hours or more, more preferably 10,000 g / m² 2 • 24 hours or more is mentioned. Regarding the upper limit of this moisture permeability, as a limitation of the measurement method, it is 13,000 to 15,000 g / m². 2 It will be approximately 24 hours.
[0422] In the laminated fabric of this disclosure, the peel strength between the woven or knitted fabric and the breathable waterproof layer, measured according to 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 other applications.
[0423] • Manufacturing method of laminated fabric The method for manufacturing the laminated fabric is not particularly limited, but examples include the first and second manufacturing methods shown below. First manufacturing method: Includes the step of forming the moisture-permeable waterproof layer by applying the resin constituting the moisture-permeable waterproof layer to the surface of a woven or knitted fabric. A second manufacturing method includes the steps of forming an adhesive layer on a woven or knitted fabric or a breathable waterproof layer, and bonding the woven or knitted fabric and the breathable waterproof layer via the adhesive layer.
[0424] In the first manufacturing method, a coating method can be used to apply the resin constituting the moisture-permeable waterproof layer to the surface of the woven or knitted fabric. In the coating method, a knife coater or a comma coater can be used. Furthermore, 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, a lamination method is used as a method for forming an adhesive layer on a woven or knitted fabric or a breathable waterproof layer. In the lamination method, a resin solution or a hot melt method can be used to form the adhesive layer. First, a resin composition for forming a breathable waterproof layer (for example, a resin composition containing resin and an organic solvent) is applied to the surface of a release agent (release paper, release cloth, or release film, etc.) with a clearance, and the breathable waterproof layer is formed while adjusting the thickness, and then dried and heat-treated to obtain a film. The release agent can be removed as appropriate after lamination or curing. In addition, when laminating by the hot melt method, the release agent can be peeled off and the film can be laminated on its own. Furthermore, the breathable waterproof membrane can be laminated with membranes manufactured using solvent-free extrusion methods such as the T-die method and inflation, porous membranes manufactured by electrospinning, and porous membranes made of PTFE, PE, PP, etc.
[0426] Then, an adhesive layer is formed on the woven or knitted fabric or the breathable waterproof layer. For example, if using a resin solution, a two-component curing polyurethane resin solution, adjusted to a viscosity in the range of 500 to 5000 mPa·s, may be applied to the entire surface or in a pattern. After drying, an adhesive layer is formed, and the woven or knitted fabric and the breathable waterproof layer are bonded together via the adhesive layer, and the second manufacturing method can be carried out by pressing or heat-pressing the two together.
[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 terms, it is more preferable to use one that melts in a temperature range of about 80 to 150°C. In this case, first, the hot melt resin is melted while considering the melting point of the resin and the viscosity when melted. Then, the melted resin is applied to the woven or knitted fabric or the breathable waterproof layer to form an adhesive layer, and the woven or knitted fabric and the breathable waterproof layer are bonded together and pressed to carry out the second manufacturing method. Alternatively, if texture is important, the resin can be applied to the breathable waterproof membrane in a pattern and bonded to the woven or knitted fabric.
[0428] Subsequently, a lining fabric can be laminated onto the breathable waterproof layer using a known and appropriate method.
[0429] • Uses of laminated fabrics Laminated fabrics offer excellent water repellency and breathable waterproofing, 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] [Processing method] The water-repellent composition of this disclosure can be applied to a substrate (particularly a fibrous substrate) by conventionally known methods as a treatment agent (particularly a surface treatment agent). The water-repellent composition of this disclosure may be diluted by dispersing it in an organic solvent or water as needed, and then applied to the surface of the substrate by known methods such as immersion coating, spray coating, foam coating, etc., and then dried. After drying, a fibrous product with the solid components of the water-repellent composition attached is obtained. If necessary, it may also be applied together with a suitable crosslinking agent and cured. Furthermore, the water-repellent composition of this disclosure can be used in combination with various additives such as water-repellent and / or oil-repellent agents, anti-slip agents, antistatic agents, texture modifiers, softeners, antibacterial agents, flame retardants, paint fixatives, wrinkle-preventing agents, drying rate modifiers, crosslinking agents, film-forming aids, compatibilizers, antifreeze agents, viscosity modifiers, ultraviolet absorbers, antioxidants, pH adjusters, insecticides, and defoaming agents. Examples of various additives may be the same as those described in "other components" in the water-repellent composition described above. The concentration of the hydrocarbon-based water-repellent resin in the treatment agent that comes into contact with the substrate may be appropriately changed depending on the application, but it may be 0.01 to 10% by weight, for example, 0.05 to 5% by weight.
[0431] [Textile products] Various examples can be given of the fibrous base material, such as cloth products and paper products.
[0432] Examples of textile products include natural animal and plant fibers such as cotton, linen, wool, and silk; synthetic fibers such as polyamide, polyester (polyethylene terephthalate is particularly preferred), polyvinyl alcohol, polyacrylonitrile, polyvinyl chloride, and polypropylene; semi-synthetic fibers such as rayon and acetate; inorganic fibers such as glass fibers, carbon fibers, and asbestos fibers; or blends thereof. Textile products include woven fabrics, knitted fabrics, and nonwoven fabrics, as well as fabrics and carpets. However, treatment may also be applied to fibers, yarns, and intermediate textile products (e.g., slivers or rovings) before they are made into fabric.
[0433] Examples of paper products include paper made from bleached or unbleached chemical pulps such as kraft pulp or sulfite pulp, bleached or unbleached high-yield pulps such as crushed wood pulp, mechanical pulp or thermomechanical pulp, recycled paper pulp such as recycled newspaper, recycled magazine, recycled corrugated cardboard or deinked paper, paper containers, and molded products made from paper. Specific examples of paper products include food packaging paper, gypsum board base paper, coated base paper, medium-grade paper, general liners and cores, neutral pure white roll paper, neutral liners, rust-preventive 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., cloth) by any known method 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 to or sprayed onto the textile substrate. The treated textile product textile substrate is preferably dried and cured by heating to exhibit water-repellent and oil-repellent properties. The heating temperature may be, for example, 100°C to 200°C, 100°C to 170°C, or 100°C to 120°C. Good performance can also be obtained with low-temperature heating (e.g., 100°C to 140°C) in this disclosure. The heating time may be 5 seconds to 60 minutes in this disclosure, for example, 30 seconds to 3 minutes.
[0435] Alternatively, the polymer may be applied to the fibrous substrate by a cleaning method, for example, by washing or dry cleaning.
[0436] The fibrous substrate to be treated may be a cloth, which includes woven fabrics, knitted fabrics and nonwoven fabrics, cloth in the form of clothing and carpets, etc., but may also be a fiber or yarn or intermediate fibrous product (e.g., sliver or roving yarn, etc.). The water-repellent compositions of this disclosure are particularly effective in making fibrous products (e.g., synthetic fibers) water-repellent.
[0437] The fibers constituting the fibrous base material may be natural fibers, synthetic fibers, semi-synthetic fibers, regenerated fibers, or inorganic fibers. The fibers may be used individually or in combination of two or more types.
[0438] Examples of natural fibers include cellulose fibers such as cotton, flax, and pulp, as well as chitin, chitosan, wool, and silk. Specific examples of wood pulp include mechanical pulps such as groundwood pulp (GP), pressured groundwood pulp (PGW), and thermomechanical pulp (TMP); chemical pulps such as high-yield unbleached softwood kraft pulp (HNKP; N material), bleached softwood kraft pulp (NBKP; N material, NB material), unbleached hardwood kraft pulp (LUKP; L material), and bleached hardwood kraft pulp (LBKP, L material); recycled paper pulp such as deinking pulp (DIP) and waste pulp (WP), and semi-chemical pulp (CP).

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.
[0440] Alternatively, the fibrous base material may be leather. The manufactured polymer may be applied to the leather in the form of an aqueous solution or aqueous emulsion at various stages of leather processing, for example, during the wetting process or during the finishing process, in order to make the leather hydrophobic and oleophobic. Alternatively, the fibrous substrate may be paper. The manufactured polymer may be applied to pre-formed paper, or it may be applied at various stages of papermaking, for example, during the drying period of the paper.
[0441] "Treatment" means applying the water-repellent composition to a substrate by immersion, spraying, coating, etc. Through treatment, the polymer (A), which is the active ingredient of the water-repellent composition, penetrates into the interior of the substrate and / or adheres to the surface of the substrate. In other words, through treatment, a substrate (e.g., a textile product) to which the polymer (A) of the water-repellent composition of this disclosure is attached is obtained.
[0442] [Pretreatment of textile substrates] The fibrous substrate may be pre-treated before being treated with the water-repellent composition of this disclosure. Pre-treating the fibrous substrate can impart excellent fastness to the fibrous substrate after treatment with the water-repellent composition.
[0443] Examples of pretreatments for fiber substrates include cationization by reaction with reactive quaternary ammonium salts, anionization by sulfonation, carboxylation, phosphorylation, etc., acetylation, benzoylation, carboxymethylation, grafting, tannic acid treatment, and polymer coating after anionization.
[0444] The method for pre-treating the fiber substrate is not limited, but it can be pre-treated by conventionally known methods. The pre-treatment solution may be diluted by dispersing it in an organic solvent or water as needed, and then applied to the surface of the fiber substrate by known methods such as immersion coating, spray coating, or foam coating, followed by drying. The pH and temperature of the pre-treatment solution may be adjusted according to the desired degree of treatment. As an example of a method for pre-treating a fiber substrate, a method of pre-treating the fiber substrate with a hydrocarbon-based water repellent will be described in detail.
[0445] The pretreatment method for the fiber substrate involves applying -SO3M to the fibers. 1 (In the formula, M 1 (represents a monovalent cation) a monovalent group represented by -COOM 2 (In the formula, M 2 A monovalent group represented by (where is a monovalent cation), and -OP(O)(OX 1 )(OX 2 )(wherein, X 1 and X 2The process may include a step of conferring at least one functional group (hereinafter sometimes referred to as a "specific functional group") selected from the group consisting of monovalent groups (each representing a hydrogen atom or an alkyl group having 1 to 22 carbon atoms).
[0446] M 1 Examples include H, K, Na, or ammonium ions which may have substituents. 2 Examples include H, K, Na, or ammonium ions which may have substituents. 1 or X 2 If it 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 above-mentioned 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 above-mentioned specific functional group is attached to the fiber material. The attachment of the compound may be such that a portion of the compound and a portion of the fiber are chemically bonded, as long as a sufficient amount of the above-mentioned specific functional group remains. (ii) Prepare a fiber in which the above-mentioned specific functional group is directly introduced into the material constituting the fiber.
[0448] (i) For example, a functional group-containing fiber can be obtained by a functional group introduction step in which the fiber material is treated with a pretreatment solution containing one or more compounds having the above-mentioned specific functional group.
[0449] There are no particular restrictions on the material of the fiber material, and examples 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 fiber material may take any form, such as fibers (tow, sliver, etc.), yarn, knitted fabrics (including interwoven fabrics), woven fabrics (including interwoven fabrics), nonwoven fabrics, and paper.
[0450] In this embodiment, from the viewpoint of obtaining good water repellency in the resulting textile product, it is preferable to use a fiber material containing polyamide and polyester as a base material. In particular, it is preferable to use nylon such as nylon 6 and nylon 6,6, polyester such as polyethylene terephthalate (PET), polytrimethyl terephthalate, and polylactic acid, and mixed fibers containing these.
[0451] The above -SO3M 1 As a compound having this property, phenolic polymers can be used. Examples of such phenolic polymers include those containing at least one compound represented by the following general formula.
[0452] JPEG0007846437000010.jpg4770 [where, X 2 ha-SO3M 3 (In the formula, M 3 (where n represents a monovalent cation) or a group represented by the following general formula, where n is an integer between 20 and 3000.

[0457] The above-COOM 2 Examples of compounds having this property include polycarboxylic acid polymers.
[0458] As polycarboxylic acid polymers, for example, polymers synthesized by conventionally known radical polymerization methods using acrylic acid, methacrylic acid, maleic acid, etc. as monomers, or commercially available polymers can be used.
[0459] One method for producing polycarboxylic acid polymers is to add a radical polymerization initiator to an aqueous solution of the monomer and / or its salt, and heat the reaction at 30 to 150°C for 2 to 5 hours. At this time, alcohols such as methanol, ethanol, isopropyl alcohol, or aqueous solvents such as acetone may be added to the aqueous solution of the monomer and / or its salt. Examples of radical polymerization initiators include persulfates such as potassium persulfate, sodium persulfate, and ammonium persulfate, redox polymerization initiators using combinations of persulfates and sodium bisulfite, hydrogen peroxide, and water-soluble azo polymerization initiators. These radical polymerization initiators may be used alone or in combination of two or more. Furthermore, during radical polymerization, a chain transfer agent (e.g., octyl thioglycolate) may be added to adjust the degree of polymerization.
[0460] In radical polymerization, copolymerizable monomers can be used in addition to the monomers mentioned above. Examples of copolymerizable monomers include vinyl monomers such as ethylene, vinyl chloride, and vinyl acetate, as well as acrylamide, acrylates, and methacrylates. Acrylates and methacrylates are preferably those having a hydrocarbon group with 1 to 3 carbon atoms, which may have substituents such as hydroxyl groups. 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 individually or in combination of two or more.
[0461] The carboxyl groups in the polycarboxylic acid polymer may be free or neutralized by alkali metals or amine compounds. Examples of alkali metals include sodium, potassium, and lithium, while examples of amine compounds include ammonia, monoethanolamine, diethanolamine, and triethanolamine.
[0462] The weight-average molecular weight of the polycarboxylic acid polymer is preferably 1,000 to 20,000, and more preferably 3,000 to 15,000, from the viewpoint of obtaining good water repellency in the resulting textile product.
[0463] For polycarboxylic acid polymers, commercially available products such as "NeoCrystal 770" (manufactured by Nikka Chemical Co., Ltd., product name) and "Cellopol PC-300" (manufactured by Sanyo Chemical Industries, Ltd., product name) can be used.
[0464] The above - OP(O)(OX 1 )(OX 2 Examples of compounds having the following general formula include phosphate ester compounds. JPEG0007846437000012.jpg3336[where, X 1 or X 2 This is synonymous with the above, X 3 This represents an alkyl group with 1 to 22 carbon atoms.
[0465] As the phosphate ester compound mentioned above, phosphate monoesters, diesters, and triesters in which the alkyl ester portion has an alkyl group having 1 to 22 carbon atoms, as well as mixtures thereof, can be used.
[0466] From the viewpoint of obtaining good water repellency in the resulting textile product, it is preferable to use lauryl phosphate esters and decyl phosphate esters.
[0467] For the phosphate ester compound, commercially available products such as "Phosphanol ML-200" (manufactured by Toho Chemical Industry Co., Ltd., trade name) can be used.
[0468] The pretreatment solution containing one or more compounds having the above-mentioned specific functional groups can, for example, be an aqueous solution of the compounds described above. The pretreatment solution may also contain acids, alkalis, surfactants, chelating agents, etc.
[0469] Methods for treating fibrous materials with the above-mentioned pretreatment solution include, for example, padding, immersion, spraying, and coating. For padding, for example, methods using padding equipment described on pages 396-397 of the Dictionary of Textile Dyeing and Processing (published in 1963 by Nikkan Kogyo Shimbun) and pages 256-260 of Color Dyeing Chemistry III (published in 1975 by Jikkyo Shuppan Co., Ltd.) can be used. For coating, for example, methods using coating machines described on pages 473-477 of the General Catalog of Dyeing and Finishing Equipment (published in 1981 by Senryo-sha) can be used. For immersion, for example, methods using batch-type dyeing machines described on pages 196-247 of the General Catalog of Dyeing and Finishing Equipment (published in 1981 by Senryo-sha) can be used, and liquid flow dyeing machines, air flow dyeing machines, drum dyeing machines, winch dyeing machines, washer dyeing machines, cheese dyeing machines, etc. can be used. Examples of spray treatments include air sprays that atomize the treatment solution using compressed air, and air sprays that use a hydraulic atomization system. The concentration of the treatment solution and the treatment conditions such as heat treatment after application can be adjusted as appropriate, taking into account the purpose, performance, and other conditions. If the pretreatment solution contains water, it is preferable to dry it to remove the water after it has been applied to the fiber material. There are no particular restrictions on the drying method, and either a dry heat method or a wet heat method may be used. There are no particular restrictions on the drying temperature, but for example, drying at room temperature to 200°C for 10 seconds to several days is sufficient. If necessary, after drying, heat treatment may be performed at a temperature of 100 to 180°C for about 10 seconds to 5 minutes.
[0470] Furthermore, if the fiber material is to be dyed, the pretreatment with the pretreatment solution may be performed before dyeing or in the same bath as the dyeing. However, if reducing soaping is performed, there is a risk that the compounds having the specific functional groups (e.g., phenolic polymer compounds, etc.) that have been adsorbed during the process may be removed. Therefore, it is preferable to perform the pretreatment after reducing soaping following dyeing.
[0471] The treatment temperature during the immersion process can be 60 to 130°C. The treatment time can be 5 to 60 minutes.
[0472] In the functional group introduction step using the pretreatment solution, it is preferable to treat the material in such an amount that the amount of compound having the specified functional group attached is 1.0 to 7.0 parts by weight per 100 parts by weight of the fiber material. Within this range, a high level of both durable water repellency and texture can be achieved.
[0473] The pretreatment solution is preferably adjusted to a pH of 3-5. pH adjustment can be done using pH adjusting agents such as acetic acid or malic acid.
[0474] The pretreatment solution may also contain salt to effectively adsorb the compound having the above-mentioned specific functional group onto the fiber material through a salting-out effect. Examples of salts that can be used include sodium chloride. Examples include sodium carbonate, ammonium sulfate, and sodium sulfate.
[0475] In the functional group introduction step using the pretreatment solution, it is preferable to remove any compounds having the specified functional groups that have been excessively treated. One method of removal is washing with water. By performing sufficient removal, it is possible to suppress the inhibition of the development of water repellency in the subsequent water-repellent treatment, and in addition, the texture of the resulting textile product will be good. Furthermore, it is preferable to thoroughly dry the resulting functional group-containing fibers before contacting them with a hydrocarbon-based water repellent.
[0476] (ii) Examples of fibers in which the above-mentioned specific functional groups are directly introduced into the material constituting the fiber include cationic dyeable polyester (CD-PET).
[0477] From the viewpoint of obtaining good water repellency in the resulting textile product, the functional group-containing fibers preferably have a surface zeta potential of -100 to -0.1 mV, and more preferably -50 to -1 mV. The surface zeta potential of the fibers can be measured, for example, using the 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] <Testing Method> The examination procedure is as follows:
[0480] The following equipment was used for molecular weight analysis. Measurement by gel permeation chromatography (GPC) (hereinafter referred to as "GPC measurement"). Equipment: HLC-8420GPC EcoSEC Elite-WS (manufactured by Tosoh) Column: TSKgel SuperMultiporeHZ-M (manufactured by Tosoh) Column temperature: 40℃ Solvent: tetrahydrofuran Flow rate: 0.35mL / min Detector: Differential refractive index detector
[0481] [Water repellency test] The water repellency of the test fabric was evaluated according to the spray method of JIS-L-1092 (AATCC-22). Water repellency was evaluated according to the following criteria. A higher score indicates better water repellency, and intermediate values (95, 85, 75) were assigned depending on the condition.
[0482] 100 No wetting or water droplet adhesion was observed on the surface. 90 The surface did not become wet, but the adhesion of small water droplets was observed. 80 Wetting was observed on the surface in the form of small, individual water droplets. 70. Wetness was observed on half of the surface, and small, individual wet spots were seen penetrating the fabric. 50 Wetting was observed across the entire surface. 0. Wetting was observed throughout both the front and back surfaces.
[0483] [Light oil repellency test] 0.05 mL of the test solution was dropped onto the test cloth from a height of 0.6 cm. The above procedure was repeated, dropping 5 drops onto the cloth at 4.0 cm intervals. The absorption and shape of the oil droplets were observed after 30 ± 2 seconds to evaluate the mild oleophobicity. The test solution was prepared by mixing PEG-600 and oleic acid in a mass ratio of 9:1. The surface tension of this test solution was measured using an automatic surface tensimeter DY-300 (Kyowa Interface Science Co., Ltd.) and was found to be 35.7 mN / m. The oil repellency was evaluated according to the following criteria. A indicates the best oil repellency, and D indicates significantly low oil repellency. The evaluation value was taken from the results shown by 3 or more out of 5 drops. Intermediate values (A-, B-, C+) were assigned depending on the condition.
[0484] A [Wet / Spread] Transparent (Not wet) [Shape of oil droplet] Rounded B [Wet / Stained] The edges and bottom are slightly discolored. [Shape of oil droplet] Rounded C [Wetness / Staining] Some staining is visible. [Shape of oil droplets] Contact angle is 35° or less D [Wet / Spread] Completely soaked [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 160N, and the seam slippage (mm) was measured. A smaller seam slippage value indicates better slip resistance, and it is most preferable that it is equivalent to untreated fabric, i.e., 2.0 mm or less.
