In R 51 and R 53 In this context, alkyl groups with 1 to 40 carbon atoms and aryl groups with 6 to 40 carbon atoms can be unsubstituted or substituted.
[0149] R 51 and R 53 Specific examples include: methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, dodecyl, tetradecyl, hexadecyl, octadecyl; cyclopentyl, cyclohexyl, cycloheptyl; phenyl, tolyl, naphthyl, or groups in which some or all of the hydrogen atoms bonded to these groups are replaced by halogen atoms, amino groups, cyano groups, etc. R 51 and R 53 Methyl or ethyl is preferred.
[0150] In R 51 and R 53 In alkoxy groups, those with 1 to 40 carbon atoms can be either straight-chain or branched. Examples of alkoxy groups with 1 to 40 carbon atoms include methoxy, ethoxy, propoxy, and butoxy.
[0151] Organosilicon can have at least one long-chain hydrocarbon group. For example, R in formula (S1) can be... 51 At least one of them, R 53 At least one of them, or R 51 and R 53Each of them has at least one long-chain hydrocarbon group, or R 51 At least one (e.g., one) is a long-chain hydrocarbon group.

[0153] a is an integer greater than or equal to 0. From the viewpoint of being easy to manufacture and obtain industrially, a can be less than 40, less than 30, less than 20, and preferably less than 30.
[0154] The sum of a and b is 5 to 200. From the viewpoint of being easy to manufacture, obtain, and operate industrially, the sum of a and b is preferably 10 to 100, more preferably 40 to 60. a can be 0 to 150, for example 1 to 100. The lower limit of b can be 1, 2, or 3, and the upper limit of b can be 150, 10, or 5.
[0155] When a or b is 2 or more, there are multiple Rs. 51 and R 52 They can be the same or different.
[0156] Preferred R 51 With R 53 The basis (e.g., R is represented by the following formula (S2)) 51 R 52 base and R 53 More than 50 mol% of the total (including bases) are methyl.
[0157] The order of repeating units enclosed in a or b is not limited to the order represented in the chemical formula and is arbitrary. That is, organosilicon can be a random polymer or a block polymer.
[0158] For example, organosilicon can be a polymer as shown in the following formula: (R)53 )3Si-O-[-Si(R 51 )2-O-】 a -[-Si(R 51 (R) 52 )-O-】 b -Si(R) 53 3 (S2).
[0159] [In the formula, R] 51 Each of the following can independently represent a hydrogen atom, an alkyl group with 1 to 40 carbon atoms, an aryl group with 6 to 40 carbon atoms, an alkoxy group with 1 to 40 carbon atoms, or a long-chain hydrocarbon group.

[0160] Examples of organosilicon are as follows. [In the formula, a represents an integer from 0 to 150,] b represents an integer from 1 to 150. (a+b) ranges from 5 to 200. n is an integer from 1 to 36 (preferably n is a long-chain hydrocarbon group). Organosilicones can be synthesized using existing, well-known methods. For example, organosilicones can be obtained by hydrosilylation of an organosilicon with a SiH group to an α-olefin.
[0161] Examples of organosilicones with SiH groups include methyl hydrogen-containing organosilicones with a degree of polymerization of 10 to 200, or copolymers of dimethylsiloxane and methyl hydrogen-containing siloxane. Among these, methyl hydrogen-containing organosilicones are preferred from the viewpoint of being easily manufactured and readily available industrially. Hydrogen-containing organosilicones (e.g., methyl hydrogen-containing organosilicones) refer to compounds in which a portion of the side chain of a polydiorganosiloxane is replaced by hydrogen, and the hydrogen atom is directly bonded to the silicon atom. When using hydrogen-containing organosilicones, a catalyst can be used to improve reactivity. For example, zinc, tin, manganese, cobalt, iron, and amine catalysts can be used. As these catalysts, organic acid metal salts are preferred, and as organic acids, fatty acids are preferred. From the viewpoint of excellent operability, zinc stearate, etc., can be used. From the perspective of easily achieving the desired effect, it is preferable to use 10 to 40% of the catalyst relative to the methyl hydrogen-containing organosilicon. Two or more types of amino-modified, epoxy-modified, carboxyl-modified, and methyl hydrogen-containing organosilicones can be mixed. Organosilicones that are all reactive and have film-forming properties are preferred. The term "film-forming property" refers to the fact that after the organosilicon is applied to the fiber surface in an emulsion state, it does not form an oily or gel-like substance, but rather a solid film.

[0168] (Reactive organosilicon) Organosilicones can include reactive organosilicones. Examples of reactive organosilicones include polysiloxanes with reactive groups on side chains, at single ends, at both ends, or on both sides. However, from the viewpoint of excellent slip resistance and water repellency, it can be a polysiloxane with reactive groups on side chains and / or at both ends. There are no particular limitations on reactive organosilicones as long as they contain reactive groups within the molecule; examples include amino-modified organosilicones, epoxy-modified organosilicones, carboxyl-modified organosilicones, and hydrogen-modified organosilicones. Reactive organosilicones can also be substances in which one or more substituents in formula (S1) or formula (S2) above are replaced by reactive groups.
[0169] Examples of amino-modified organosilicones include substances having an amino group bonded to an organic group directly bonded to a silicon atom. The organic group can be any of an alkylene group or a divalent aromatic group. As an alkylene group, it is preferred that it has 2 or more carbon atoms. As a divalent aromatic group, it is preferred that it has 6 or more carbon atoms. The amino group can be any of a primary amino group, a secondary amino group, or a tertiary amino group.

These functional groups can be present on the side chains of polysiloxanes or at the ends.
[0170] Examples of epoxy-modified organosilicones include substances having an epoxy group bonded to an organic group directly bonded to a silicon atom. The organic group can be any of an alkylene group or a divalent aromatic group. In this form, it is typically bonded to the aforementioned organic group in the form of a glycidyl ether. Examples of such functional groups include 3-epoxypropoxypropyl and 2-epoxypropoxyethyl. These functional groups can be present on the side chain of the polysiloxane or at the end.
[0171] Examples of carboxyl-modified organosilicones include substances having a structure in which a carboxyl group is bonded to an organic group directly bonded to a silicon atom.

Silicone resins composed only of M units and silicone resins composed only of Q units are excluded. From the viewpoint of maximizing the effects of the present invention, silicone resin (B) is preferably free of R₂SiO₂. 2/2 Unit (D unit).
[0173] The silicone resin is preferably in a sol state. Examples of R include methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, hexyl, octyl, 2-ethylhexyl, decyl, cetyl, stearyl, etc., but considering the stability of silicone resin (B) in the sol state, the availability and price of raw materials, R is preferably methyl, and particularly preferably more than 90% of all R is methyl. However, R can also contain different types of groups.
[0174] In organosilicon resin containing R2SiO 2/2 When D-units are used, the low slippage property of the water-repellent composition may be compromised. Additionally, silicone resins composed solely of Q-units may hinder the water-repellent properties of the composition.
[0175] The structure of the silicone resin can be exemplified as (i) composed of M units and Q units, (ii) composed of M units, T units and Q units, (iii) composed of M units and T units, (iv) composed of T units and Q units, and (v) composed only of T units.

[0178] A detailed description is provided of a method for manufacturing silane compounds by hydrolyzing them in water.

From the perspectives of operability, ease of distillation removal of byproducts, and ease of obtaining raw materials, methoxysilanes or ethoxysilanes are preferred. Mixtures of one or more of these silane compounds can also be used.
[0179] As a method for hydrolyzing silane compounds in water, conventional methods that are generally known can be used. That is, the method of hydrolyzing the silane compound dropwise into the water while carrying out the hydrolysis reaction, or the method of mixing the water and the silane compound together before carrying out the hydrolysis reaction.
[0180] A hydrolysis catalyst can be used when carrying out the hydrolysis reaction. Existing known catalysts can be used, and both acidic and basic catalysts can be employed. In the case of an acidic catalyst, 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 a basic catalyst, alkali metal salts such as sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, and sodium bicarbonate, alkali metal silanodes such as sodium siloxide and potassium silanodes, amines such as triethylamine, diethylamine, and aniline, and ammonia can be used. The amount of catalyst added is preferably adjusted to adjust the pH of the aqueous solution to 2-7 or 7-12. Furthermore, after the reaction is complete, a neutralizing agent can be added as needed to neutralize the acidic or basic catalyst.
[0181] A surfactant can be added to the aqueous solution to disperse the silane compound and the hydrolysis products in the water. There are no particular limitations on the surfactant; anionic surfactants such as alkyl sulfates, alkylbenzene sulfonates, and alkyl phosphates; nonionic surfactants such as polyoxyethylene alkyl ethers, polyoxyethylene propylene 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 alkyl imidazolines can be used alone or in combination of two or more. Additionally, substances exhibiting acidity or alkalinity can also serve as hydrolysis catalysts. There are no particular limitations on the amount of surfactant added, but 1 to 50 parts by weight relative to 100 parts by weight of the silane compound is preferred. Less than 1 part by weight will not provide sufficient surfactant effect, while more than 50 parts by weight may impair the water-repellent properties of the agent.
[0182] Hydrolysis catalysts and surfactants can be added to a mixture of water and silane compounds as needed, and the hydrolysis reaction can be carried out at 0–90°C for 10 minutes to 24 hours. Afterwards, a neutralization reaction is performed as needed, thereby obtaining an organosilicon resin. Furthermore, alcohols and neutralizing salts generated as byproducts of the hydrolysis reaction can be removed by vacuum distillation or filtration. Various additives can be incorporated into this organosilicon resin. For example, preservatives and thickeners can be added depending on the intended use.

The average primary particle size can be determined using a microscope (scanning electron microscope or transmission electron microscope). Specifically, the raw material is observed from above at any magnification using a microscope. Then, when the particle shape is spherical, its diameter is considered the particle size; when it is non-spherical, the average of its longest and shortest diameters is considered the particle size.

The liquid media listed above can be used as the organic solvent. The organic solvent can be a water-soluble glycol-based solvent, such as ethylene glycol or propylene glycol.
[0275] In emulsion polymerization, the organic acids listed above may also be added. For example, the organic acid may be a carboxylic acid such as acetic acid. Relative to 100 parts by weight of the total monomer, the organic acid may be, for example, more than 0.01 parts by weight, more than 0.1 parts by weight, and less than 1 part by weight, less than 0.5 parts by weight.
[0276] Next, an emulsifier can be added to the mixture.
[0277] As emulsifiers, well-known emulsifiers can be listed, such as cationic emulsifiers and anionic emulsifiers.
[0278] In addition, the surfactants mentioned above can also be used as emulsifiers.
[0279] Furthermore, the emulsifier may contain a reactive emulsifier. In the case where the emulsifier contains a reactive emulsifier, the non-fluorinated copolymer (A) (the polymer of the aforementioned monomers) becomes a polymer containing structural units derived from the reactive emulsifier.
[0280] When the non-fluorinated copolymer (A) is a polymer containing structural units derived from reactive emulsifiers, the water repellency is not reduced, and the stability of the product of the aqueous dispersion (repellent composition) is improved.
[0281] Reactive emulsifiers are emulsifying and dispersing agents with free radical reactivity, that is, emulsifiers with one or more polymerizable unsaturated groups in their molecules, and are emulsifiers that can copolymerize with the aforementioned monomers.
[0282] Examples of reactive emulsifiers include those disclosed in Japanese Patent Application Publication No. 2017-25440, with the reactive emulsifier shown in the following formula being a preferred example. In the above formula, R 10 It refers to an organic residue with an olefinic unsaturated double bond having 12 to 20 carbon atoms.
[0283] R 11 It indicates an oxoalkylene group with 2 to 10 carbon atoms, preferably an oxoethylene group.
[0284] When the reactive emulsifier is the reactive emulsifier shown in the above formula, the water-repellent property is not reduced, and the stability of the product of the aqueous dispersion (repellent composition) is improved.
[0285] Examples of reactive emulsifiers as shown in the above formula include polyoxyethylene alkylphenol and the like.
[0286] Emulsifiers can be used alone or in combination of two or more.
[0287] The proportion of emulsifier relative to the total amount of monomers (100 parts by weight) can be, for example, 5 parts by weight or more, and for example, 18 parts by weight or less.
[0288] Furthermore, relative to the total amount of isocyanate derivative (B) and nonfluorinated copolymer (A) of 100 parts by weight, the proportion of emulsifier can be, for example, 8 parts by weight or more, and for example, 20 parts by weight or less.
[0289] In addition, the proportion of emulsifier relative to the water-repellent composition can be, for example, 0.5% by weight or more, and for example, 5% by weight or less.
[0290] Next, the above components are mixed, the mixture is stirred, and ultrasound is applied to the mixture to emulsify it.
[0291] As a mixing method, a homogenizer, an ultrasonic homogenizer, a pressure homogenizer, a mixer, a porous membrane pressurization disperser, or other dispersers can be used, with a homogenizer being preferred.
[0292] The stirring conditions can be appropriately set. When using a homogenizer, the speed should be set to, for example, 500 rpm or more and 10,000 rpm or less. The stirring time should be, for example, 0.5 minutes or more and 10 minutes or less, preferably 5 minutes or less. The stirring temperature should be, for example, 50°C or more and 90°C or less.
[0293] Next, if a portion of the monomer was incorporated during the preparation of the above mixture, the remaining portion of the monomer is incorporated into the mixture.
[0294] Next, a polymerization initiator is added to the mixture.
[0295] Examples of polymerization initiators include: azo compounds, such as azobisisobutylamidine dihydrochloride and azobisisobutyronitrile; water-soluble polymerization initiators, such as potassium persulfate, ammonium persulfate, and other persulfate compounds; and oil-soluble polymerization initiators, such as benzoyl peroxide, di-tert-butyl peroxide, lauroyl peroxide, cumene hydroperoxide, tert-butyl perpentanoate, and diisopropyl percarbonate, etc. Azo compounds are preferred, and azobisisobutyronitrile is more preferred.
[0296] The proportion of polymerization initiator relative to 100 parts by weight of monomer can be, for example, more than 0.01 parts by weight, and can be, for example, less than 10 parts by weight.
[0297] Chain transfer agents can also be added to the mixture as needed.
[0298] Examples of chain transfer agents include mercapto-containing compounds such as lauryl thiols, thioglycols, and thioglycerols (especially alkyl thiols with 1 to 30 carbon atoms); inorganic salts such as sodium hypophosphite and sodium bisulfite; lauryl thiols are preferred.
[0299] The proportion of chain transfer agent relative to 100 parts by weight of monomer can be, for example, more than 0.01 parts by weight, and can be, for example, less than 10 parts by weight.
[0300] The mixture is then heated to polymerize the monomers.
[0301] As for heating conditions, the heating temperature can be, for example, above 40°C or below 80°C; in addition, the heating time can be, for example, above 1 hour or below 6 hours.
[0302] This yields an emulsion of non-fluorinated copolymer (A), resulting in a water-repellent composition containing isocyanate derivative (B) and non-fluorinated copolymer (A) (emulsion).
[0303] In the first method, the monomer constituting the above-mentioned non-fluorinated copolymer (A) is polymerized in the presence of the isocyanate derivative (B), but the isocyanate derivative (B) can also be added after the monomer is polymerized (the second method). Alternatively, the monomer can be polymerized in the presence of a surfactant and a liquid medium, followed by the addition of the isocyanate derivative (B) (the third method).
[0304] The third method is identical to the manufacturing method described above, except that the monomers constituting the non-fluorinated copolymer (A) are polymerized in the absence of the isocyanate derivative (B). Combining the non-fluorinated copolymer (A) obtained using the third method with the isocyanate derivative (B) yields the water-repellent composition of the present invention.
[0305] Alternatively, after preparing a non-fluorinated copolymer (A) by polymerizing the monomer, the obtained non-fluorinated copolymer (A) can be combined with an isocyanate derivative (B) (fourth method). Furthermore, after preparing a non-fluorinated copolymer (A) by polymerizing the monomer, the obtained non-fluorinated copolymer (A), an isocyanate derivative (B), a surfactant, and a liquid medium can be combined (fifth method).
[0306] In the fourth and fifth methods, examples of polymerization methods include solution polymerization, suspension polymerization, and emulsion polymerization.
[0307] In the case of solution polymerization, the monomer is dissolved in an organic solvent in the presence of the above-mentioned polymerization initiator, and then heated while stirring after nitrogen purging.
[0308] The above-mentioned polymerization initiator can be used as a polymerization initiator. The proportion of the polymerization initiator relative to 100 parts by weight of the monomer can be, for example, 0.01 parts by weight or more, and can be, for example, 20 parts by weight or less, preferably 10 parts by weight or less.
[0309] Organic solvents can be those listed above for liquid media. Examples of organic solvents include glycols (e.g., glycols with 2 to 40 carbon atoms, specifically ethylene glycol, propylene glycol, etc.), esters (e.g., esters with 2 to 40 carbon atoms, specifically ethyl acetate, butyl acetate), ketones (e.g., ketones with 2 to 40 carbon atoms, specifically methyl ethyl ketone, diisobutyl ketone, methyl isobutyl ketone), and alcohols (e.g., alcohols with 1 to 40 carbon atoms, specifically ethanol, butanol, isopropanol). Water-soluble glycol-based solvents (e.g., ethylene glycol, propylene glycol, etc.) are preferred as organic solvents.
[0310] The proportion of organic solvent relative to 100 parts by weight of monomer can be, for example, 10 parts by weight or more, preferably 50 parts by weight or more, and can be, for example, 2000 parts by weight or less, preferably 1000 parts by weight or less.
[0311] As heating conditions, the heating temperature can be, for example, above 30°C or below 120°C; the heating time can be, for example, above 1 hour or below 10 hours.
[0312] As described above, a non-fluorinated copolymer (A) can be obtained.
[0313] Then, after generating a non-fluorinated copolymer (A) through solution polymerization, the organic solvent is removed, and the non-fluorinated copolymer (A) is co-integrated with the isocyanate derivative (B) into a surfactant and a liquid medium, thereby preparing an emulsion of the non-fluorinated copolymer (A).
[0314] <Uses of the water-repellent composition> Examples of uses of the water-repellent composition of the present invention include external treatment agents (surface treatment agents) or internal treatment agents, repellents (water-repellent agents, oil-repellent agents or water-repellent and oil-repellent agents, etc., especially water-repellent agents), antifouling agents, stain removers, release agents, mold release agents (external mold release agents or internal mold release agents), etc.
[0315] <Method for manufacturing processed products> The method for manufacturing the treated article of the present invention includes the step of applying the water-repellent composition of the present invention to a substrate (particularly a fiber substrate).
[0316] [Processed Products] Examples of substrates treated with the water-repellent composition of the present invention include fiber products, 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, kiln products, plastics, coatings, and plaster. Various examples of fiber products can be listed. Examples include: natural plant and animal fibers 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 cellulose acetate; inorganic fibers such as glass fiber, carbon fiber, and asbestos fiber; or blends thereof. As an example of a substrate treated with the water-repellent composition, a woven fabric will be described in detail.
[0317] (woven fabric) • Manufacturing method of woven fabrics The woven fabric can be obtained by weaving the above-mentioned blended yarns to obtain the base fabric, followed by post-processing and water-repellent finishing. Weaving can be done using known looms or knitting machines, and the preparatory processes before weaving can also use known equipment.
[0318] In addition, the base fabric is first scouring and relaxing in the post-processing stage. Scouring and relaxing can be carried out continuously or in batches at a temperature of 80–130°C. It is generally preferred to carry out the process in batches at a temperature below 100°C, and it is particularly preferred to use a high-pressure liquid flow dyeing machine equipped with nozzles.
[0319] After scouring and relaxation, the knitted fabric is pre-set. Pre-setting is typically done using a needle tenter frame, with a dry heat treatment at 170–200°C for 30–120 seconds. After pre-setting, dyeing is carried out according to standard methods, followed by final setting as needed.
[0320] After post-processing, the woven fabric can be subjected to a water-repellent treatment. In this treatment, an aqueous solution containing a water-repellent agent (which can be the water-repellent agent composition of this invention) is first prepared. Then, based on methods such as padding, spraying, contact roller coating, or slot coating, the post-processed woven fabric is coated with the aqueous solution and subjected to a dry heat treatment at 105–190°C for 30–150 seconds. Depending on the requirements, the aqueous solution may also contain a crosslinking agent, softener, antistatic agent, etc. After the water-repellent treatment, the woven fabric can be further calendered to improve its water-repellent properties.
[0321] Woven fabrics can be used for clothing, especially for uniforms, women's wear, and sportswear.
[0322] •Layered fabric The fabric can also be provided as a laminated fabric in which a moisture-permeable and waterproof layer is provided on one side of the woven fabric of the present invention. The moisture-permeable and waterproof layer can be directly laminated onto the woven fabric, or it can be laminated onto the woven fabric using an adhesive layer. In the case where the laminated fabric of the present invention is used for clothing or the like, it is configured such that the woven side is exposed to rainwater or the like.
[0323] • Breathable waterproof layer A breathable and waterproof layer is a layer that covers one side of a woven fabric and is formed of a resin that is both waterproof and breathable.
[0324] The breathable and waterproof layer can be formed by directly coating the woven fabric with resin (the resin constituting the breathable and waterproof layer), or by laminating it onto one side of the woven fabric using an adhesive layer described later. In this invention, the woven fabric uses a blended interwoven yarn with fine protrusions formed by winding or loosening. Therefore, these protrusions are firmly wrapped around the adhesive layer or the breathable and waterproof layer, thus exhibiting an anchoring effect, making it less likely for the woven fabric and the breathable and waterproof layer to peel off. When using a conventional woven fabric (one whose surface does not adequately maintain the aforementioned protrusions), the anchoring effect may not be sufficiently achieved, and in this case, there is a tendency for the woven fabric and the breathable and waterproof layer to peel off easily.
[0325] The resin constituting the breathable and waterproof layer is not particularly limited, but it is preferably composed of polyurethane resin as the main component, for example, it preferably contains polyurethane resin in a proportion of 80% by weight or more. Polyurethane resin is generally suitable for forming a resin layer with both breathability and waterproofness. Among these, microporous types are preferred when considering breathability; however, in cases where prolonged exposure to rain or repeated washing is anticipated, non-porous types of breathable polyurethane can also be used instead of microporous types.
[0326] As a polyurethane resin, existing known materials can be used, which are obtained by reacting a polyisocyanate component with a polyol component.
[0327] The breathable and waterproof layer can have a microporous structure or a non-porous structure. Furthermore, in the case of a microporous structure, to ensure the desired breathability, the breathable and waterproof layer can contain inorganic micro-powders.
[0328] Examples of inorganic micropowders include those composed of silicon dioxide, aluminum oxide, or titanium dioxide. Furthermore, the average primary particle size of the inorganic micropowder is preferably around 7 to 40 nm. The content of the inorganic micropowder relative to the total amount of the breathable and waterproof layer is preferably 3 to 50% by weight, more preferably 5 to 50% by weight.
[0329] The thickness of the breathable waterproof layer is preferably 5 μm or more, more preferably 10 to 30 μm. When the thickness is within the above range, the balance between waterproofness and breathability is excellent, and it also has advantages in terms of texture or tear strength.
[0330] • Adhesive layer The laminated fabric preferably includes an adhesive layer. That is, the woven fabric and the breathable waterproof layer are preferably laminated using an adhesive layer. The reason for this is as follows. In this invention, as described above, the woven fabric is a fabric with fine protrusions on its surface formed by winding or loosening. Therefore, the protrusions are firmly wrapped with the adhesive layer, thereby exhibiting an anchoring effect, and thus the woven fabric and the breathable waterproof layer are less likely to peel off.
[0331] Furthermore, when the breathable waterproof layer is directly laminated onto the woven fabric using methods such as coating, protrusions on the surface of the woven fabric penetrate the breathable waterproof layer, sometimes resulting in pinholes and decreased water resistance and strength. Additionally, uneven coating can lead to uneven thickness of the breathable waterproof layer. To prevent this, if the surface of the woven fabric is smoothed using processes such as calendering, the number of protrusions or air-retaining layers decreases, which can sometimes reduce water repellency. Therefore, in this invention, it is preferable to laminate the woven fabric and the breathable waterproof layer using an adhesive.
[0332] There are no particular limitations on the type of adhesive used to form the adhesive layer, but an adhesive with excellent compatibility with the breathable and waterproof layer is preferred. For example, if a resin with polyurethane resin as the main component is selected as the resin for forming the breathable and waterproof layer, an adhesive layer composed of a polyurethane-based adhesive is preferred. Polyurethane-based adhesives can be any type of adhesive, such as ether-based, ester-based, or polycarbonate-based adhesives, but from the viewpoint of providing excellent breathability, ether-based adhesives are preferred.
[0333] The adhesive layer can be formed on the entire surface of one side of the woven fabric, or it can be patterned from the viewpoint of moisture permeability or texture. There are no particular limitations on the form of the pattern, and examples include dotted, linear, grid, checkered, and tortoise shell patterns, etc., all of which are preferably evenly distributed throughout.
[0334] The thickness of the adhesive layer is preferably around 10 to 100 μm, more preferably 20 to 80 μm. When the thickness is less than 10 μm, it is difficult to obtain a durable laminated fabric even if the area occupied by the adhesive is increased; when it exceeds 100 μm, there is a tendency for increased manufacturing costs without obtaining better adhesion, so neither is preferred.
[0335] Lining made of fiber fabric In the laminated fabric of the present invention, a lining fiber fabric may also be laminated on the surface of the breathable waterproof layer (the surface of the breathable waterproof layer opposite to the surface of the woven fabric of the present invention). Using the lining fiber fabric protects the breathable waterproof layer, resulting in superior water resistance (water pressure resistance) and strength. Furthermore, by laminating the lining fiber fabric, the overall stretching of the laminated fabric can be suppressed. Therefore, as a result of the stretching of the protrusions of the blended composite yarns caused by post-lamination processing or tension during wear, the reduction of these protrusions can be suppressed, maintaining better water repellency. Moreover, when a lining fiber fabric is laminated, water repellency can be further improved.
[0336] Various woven fabrics and knitted fabrics can be used as lining materials. Among these, knitted fabrics, compared to woven fabrics, tend to have more prominent lines on the surface, resulting in a less flat surface. From the viewpoint of further enhancing the anchoring effect and preventing peeling from the breathable and waterproof layer, knitted fabrics are preferred. In particular, warp-knitted fabrics are preferred because, compared to knitted structures with other structures, their elasticity is suppressed, thus preventing excessively large stitch gaps and enabling more efficient water repellency. Furthermore, warp-knitted fabrics can produce a long base fabric with fewer seams during weaving, allowing for even layering onto the breathable and waterproof layer, which is also a plus.
[0337] The material of the fibers constituting the lining fabric is not particularly limited and can be appropriately selected, but nylon fibers are preferred. This is because nylon fibers typically use acid dyes, making it less prone to the sublimation of disperse dyes into the breathable and waterproof layer, a problem that can occur with disperse dye-based fibers such as polyester. The morphology (long fibers, short fibers, or yarns) or fineness of the constituent fibers of the lining fabric is not particularly limited and can be appropriately selected without compromising the effectiveness of the invention.
[0338] • Characteristics of laminated fabric The laminated fabric exhibits excellent water resistance. As a preferred example of the water resistance of the laminated fabric of the present invention, examples include water levels measured according to the water resistance test specified in JIS L 1092:2009A (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. The upper limit of this water level is not particularly limited, and examples include 50,000 mm or 25,000 mm.
[0339] The laminated fabric exhibits excellent moisture permeability. A preferred example of the moisture permeability of the laminated fabric of this invention is a moisture permeability of 10000 g / m², measured according to the JIS L 1099:2012 B-1 method (potassium acetate method). 2• 24 hours or more, preferably 15000g / m 2 • 24 hours or more, preferably 20000g / m 2 • More than 24 hours. There is no specific upper limit for this moisture permeability; examples include 40,000 g / m². 2 • 24h or 35000g / m 2 •24h•mm.
[0340] The laminated fabric can suppress interlayer delamination between the woven fabric and the breathable waterproof layer. In the laminated fabric of the present invention, preferred examples of peel strength between the woven fabric and the breathable waterproof layer include peel strengths measured according to JIS L 1089 of 5 N / 2.54 cm or more, preferably 5 to 50 N / 2.54 cm, more preferably 6 to 30 N / 2.54 cm, and particularly preferably 9 to 25 N / 2.54 cm. To achieve peel strength within the above range, for example, a woven fabric that has not undergone calendering can be used, or an adhesive layer can be provided.
[0341] • Manufacturing method of laminated fabric There is no particular limitation on the manufacturing method of the laminated fabric. Examples of manufacturing methods include the first and second manufacturing methods shown below.
[0342] First manufacturing method: includes the process of forming the above-mentioned breathable and waterproof layer by coating the surface of the woven fabric with a resin that constitutes the above-mentioned breathable and waterproof layer.
[0343] The second manufacturing method includes a process of forming an adhesive layer on a woven fabric or a breathable waterproof layer, and a process of bonding the woven fabric to the breathable waterproof layer using the adhesive layer.
[0344] The woven fabric used in the laminated fabric (i.e., the woven fabric of the present invention described above) preferably maintains as many protrusions as possible on the surface of the fabric. For example, when the woven fabric is calendered to facilitate coating processes, the fine protrusions of the blended yarns are flattened into a flat surface, sometimes making it impossible to achieve a specific water droplet rolling angle. Moreover, during calendering, the aforementioned air-retaining layer cannot be adequately maintained, sometimes failing to achieve the desired water repellency. Therefore, it is preferable to thoroughly study the calendering conditions. For example, when calendering the woven fabric, conventional conditions that do not cause the protrusions of the blended yarns to become too low (e.g., temperature above 130°C, linear pressure 200 to 20000 N / cm) can be used. Furthermore, calendering can also be performed without heating.
[0345] In the first manufacturing method, a method for coating the surface of the woven fabric with a resin that forms a breathable and waterproof layer can be exemplified by, for example, a coating method. In the coating method, a doctor blade coater or a comma coater can be used. Furthermore, from the viewpoint of possessing excellent breathability, a wet method is preferred for obtaining the breathable and waterproof layer.
[0346] In the second manufacturing method, a lamination method can be cited as an example of a method for forming an adhesive layer on a woven fabric or a breathable waterproof layer. In the lamination method, the adhesive layer can be formed using a resin solution or by heat melting. First, gaps are provided on the surface of a release material (release paper, release cloth, or release film, etc.), and while adjusting the thickness, a breathable waterproof layer is formed and heat-treated, thereby forming a film by completely reacting a resin composition (e.g., a resin composition containing resin and organic solvent). The release material can be appropriately removed after lamination or curing.
[0347] Then, an adhesive layer is formed on the woven fabric or the breathable waterproof layer. For example, in the method using a resin solution, a two-component curing polyurethane resin solution with a viscosity adjusted to the range of 500 to 5000 mPa·s can be applied to the entire surface or in a pattern. After drying, the adhesive layer is formed, and the woven fabric and the breathable waterproof layer are bonded together using the adhesive layer. The two are then pressed together or heat-pressed together, thereby performing the second manufacturing method.
[0348] On the other hand, in the case of hot melting, a moisture-curing resin that reacts with moisture in the air is preferred, and in practical terms, a resin that melts in a temperature range of approximately 80–150°C is more preferable. In this case, firstly, the hot-melt resin is melted, depending on factors such as the resin's melting point and viscosity at melt. Then, while coating the molten resin onto the woven fabric or the breathable waterproof layer and cooling it at room temperature, it is allowed to cure, forming an adhesive layer. Subsequently, the woven fabric and the breathable waterproof layer are bonded and pressed together using the adhesive layer, thereby performing the second manufacturing method.
[0349] In the manufacturing process, the second manufacturing method is preferred. This is because when using a coating method to laminate a breathable waterproof layer, there is a risk that the breathable waterproof layer may have pinholes due to tiny protrusions on the surface of the woven fabric, which may reduce its water pressure resistance. In addition, when calendering is performed on the woven fabric to form a uniform breathable waterproof layer, the protrusions or air retention layer may be reduced, which may result in the failure to achieve the expected water repellency. This requires a detailed examination of the calendering conditions, and therefore the process itself may sometimes become cumbersome.
[0350] Then, using appropriate methods known to the public, a lining of fibrous fabric is layered on top of the breathable and waterproof layer.
[0351] • Applications of laminated fabric The laminated fabric has excellent water repellency and breathability, and the breathable and waterproof layer will not peel off even in harsh environments. Therefore, it is preferred for use in uniforms, sportswear, outdoor products and other fields used outdoors.
[0352] [Handling Method] The water-repellent composition of the present invention can be applied to a substrate as a treatment agent (especially a surface treatment agent) using existing known methods. This can be achieved by dispersing the water-repellent composition of the present invention in an organic solvent or water for dilution, applying it to the surface of the substrate using known methods such as dip coating, spray coating, or foam coating, and then drying it. After drying, a fibrous article with the solid components of the water-repellent composition adhering to it can be obtained. Alternatively, if desired, it can be applied and cured together with a suitable crosslinking agent. Furthermore, the water-repellent composition of the present invention can be used in combination with various additives such as water-repellent and / or oil-repellent agents, antislip agents, antistatic agents, texture modifiers, softeners, antibacterial agents, flame retardants, paint fixatives, antiwrinkle agents, drying speed modifiers, crosslinking agents, film-forming aids, solubilizers, antifreeze agents, viscosity modifiers, ultraviolet absorbers, antioxidants, pH adjusters, insect repellents, and defoamers. Examples of various additives are the same as those described in the "Other Components" section of the above-described water-repellent composition. The concentration of the non-fluorinated copolymer (A) in the treatment agent that comes into contact with the substrate can be varied as appropriate for the application, and can be 0.01 to 10% by weight, for example 0.05 to 5% by weight.
[0353] [Fiber Products] Various examples can be listed for fiber products used as a base material, such as cloth or paper products. Fiber products used as a base material are also called fiber-based materials.
[0354] Examples of textile products include natural plant and animal fibers 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 cellulose acetate; inorganic fibers such as glass fiber, carbon fiber, and asbestos fiber; and blends thereof.

[0356] The water-repellent composition can be applied to fibrous articles (e.g., fabrics) by any known method for treating fibrous articles with liquids. The fibrous article can be impregnated with the water-repellent composition, or the solution can be adhered to or sprayed onto the fibrous article. To exhibit water repellency, the treated fibrous article is preferably dried and cured by heating. The heating temperature can be, for example, 100°C–200°C, 100°C–170°C, or 100°C–120°C. In this invention, good performance can be obtained even with low-temperature heating (e.g., 100°C–140°C). In this invention, the heating time can be from 5 seconds to 60 minutes, for example, from 30 seconds to 3 minutes.
[0357] Alternatively, the water-repellent composition can also be applied to fiber products by washing, for example, by washing or by dry cleaning.
[0358] The treated fiber products can be fabrics, including woven fabrics (woven cloth), knitted fabrics (woven fabrics), and nonwoven fabrics, clothing-like fabrics, and carpets, but can also be fiber, yarn, or intermediate fiber products (e.g., slivers or rovings). The water-repellent composition of the present invention is particularly effective in making fiber products (e.g., synthetic fibers) water-repellent.
[0359] The fibers that make up fiber products can be natural fibers, synthetic fibers, semi-synthetic fibers, regenerated fibers, or inorganic fibers. One type of fiber can be used alone, or two or more types can be used together.
[0360] 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), press-groundwood pulp (PGW), and thermomechanical pulp (TMP); chemical pulps such as high-content unbleached coniferous kraft pulp (HNKP, N material), bleached coniferous kraft pulp (NBKP, N material, NB material), unbleached hardwood kraft pulp (LUKP, L material), and bleached hardwood kraft pulp (LBKP, L material); waste paper pulps such as deinked pulp (DIP); and semi-chemical pulps such as waste paper pulp (WP) or semi-chemical pulp (CP).

In other words, through treatment, a substrate (e.g., a fiber product) can be obtained with the non-fluorinated copolymer (A) and isocyanate derivative (B) of the water-repellent composition of this invention adhered to it.
[0366] [Pretreatment of fiber products] The fiber products can be pretreated before being treated with the water-repellent composition of the present invention. By pretreating the fiber products, the water-repellent composition can impart excellent durability to the treated fiber products.

[0368] There are no limitations on the method for pretreating fiber products; any existing known method can be used. Alternatively, the pretreatment solution can be dispersed and diluted in an organic solvent or water as needed, and then applied to the surface of the fiber product using known methods such as dip coating, spray coating, or foam coating, followed by drying. The pH and temperature of the pretreatment solution can be adjusted according to the desired level of treatment. As an example of a method for pretreating fiber products, a method using a hydrocarbon-based water-repellent agent will be described in detail.

In X 1 or X 2 When the alkyl group is alkyl, it is preferred to be an alkyl group with 1 to 22 carbon atoms, and more preferably an alkyl group with 4 to 12 carbon atoms.
[0371] Fibers containing the aforementioned specific functional groups (hereinafter sometimes referred to as "fibers containing functional groups") can be prepared by, for example, the following methods.
[0372] (i) To attach a compound having the specific functional group described above to a fibrous material. The attachment of the compound may be a state in which a portion of the compound and a portion of the fiber are chemically bonded within a range where the specific functional group remains in sufficient quantity.
[0373] (ii) A fiber in which the aforementioned specific functional groups are directly introduced into the material constituting the fiber.
[0374] In case (i), for example, a functional group-containing fiber can be obtained by treating the fiber material with a pretreatment liquid containing one or more compounds having the aforementioned specific functional groups in a functional group introduction process.
[0375] As raw materials for fiber materials, there are no particular limitations. Examples include natural fibers such as cotton, linen, silk, and wool; semi-synthetic fibers such as rayon and cellulose acetate; synthetic fibers such as polyamide (nylon, etc.), polyester, polyurethane, and polypropylene, as well as their composite fibers and blended fibers. Fiber materials can take any form, such as fibers (tows, slivers, etc.), silk, woven fabrics (including cross-knitting), woven fabrics (including interwoven fabrics), non-woven fabrics, and paper.
[0376] In this embodiment, from the viewpoint of obtaining a fiber product with good water repellency, it is preferable to use fiber materials containing polyamide and polyester as raw materials, and particularly preferable to use nylon 6, nylon 6,6 and other nylons, polyethylene terephthalate (PET), polyterephthalate trimethyl terephthalate, polylactic acid and other polyesters, as well as blended fibers containing them.

Examples of such phenolic polymers include materials containing at least one compound represented by the following general formula. [In formula (2), X] 2 Indicates - SO3M 3 (where M) 3 [This refers to a monovalent cation or a group represented by the following general formula, where n is an integer from 20 to 3000.] [In the formula, M] 4 This indicates a monovalent cation. As for the above M 3 Examples include H, K, Na, or ammonium ions that may have substituents.
[0378] As for the above M 4 Examples include H, K, Na, or ammonium ions that may have substituents.

[0380] As mentioned above, it has -COOM 2 Compounds that can be listed include polycarboxylic acid polymers.
[0381] As polycarboxylic acid polymers, polymers synthesized by conventional free radical polymerization methods using monomers such as acrylic acid, methacrylic acid, and maleic acid, or commercially available polymers can be used.
[0382] As a method for manufacturing polycarboxylate polymers, examples include adding a free radical polymerization initiator to an aqueous solution of the aforementioned monomers and / or their salts, and reacting at 30–150°C for 2–5 hours. Alternatively, alcohols such as methanol, ethanol, and isopropanol, or aqueous solvents such as acetone, can be added to the aqueous solution of the aforementioned monomers and / or their salts. Examples of free radical polymerization initiators include persulfates such as potassium persulfate, sodium persulfate, and ammonium persulfate; redox polymerization initiators combining persulfates and sodium bisulfite; hydrogen peroxide; and water-soluble azo polymerization initiators. These free radical polymerization initiators can be used alone or in combination of two or more. Furthermore, during free radical polymerization, chain transfer agents (e.g., octyl mercaptoacetate) can be added to adjust the degree of polymerization.
[0383] In free radical polymerization, in addition to the monomers mentioned above, copolymerizable monomers can also be used. Examples of copolymerizable monomers include vinyl monomers such as ethylene, vinyl chloride, and vinyl acetate; acrylamide; acrylates; and methacrylates. Acrylates and methacrylates preferably have 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 can be used alone or in combination of two or more.
[0384] In polycarboxylate polymers, the carboxyl groups can be free or neutralized by alkali metals or amine compounds. Examples of alkali metals include sodium, potassium, and lithium; examples of amine compounds include ammonia, monoethanolamine, diethanolamine, and triethanolamine.
[0385] From the viewpoint that the resulting fiber product has good water repellency, the weight-average molecular weight of the polycarboxylate polymer is preferably 1,000 to 20,000, more preferably 3,000 to 15,000.
[0386] Polycarboxylate polymers can be commercially available products such as "NEOCRYSTAL 770" (manufactured by Nichika Chemical Co., Ltd., trade name) and "SELOPOL PC-300" (manufactured by Sanyo Chemical Co., Ltd., trade name).
[0387] As mentioned above, it has -O-P(O)(OX) 1 (OX) 2 Compounds of which can be listed, for example, phosphate ester compounds represented by the following general formula. [In the formula, X] 1 or X2 The meaning is the same as above, X 3 [Represents alkyl groups with 1 to 22 carbon atoms.] As the aforementioned phosphate ester compounds, phosphate monoesters, diesters, and triesters, as well as mixtures thereof, can be used, wherein the alkyl ester portion is an alkyl group having 1 to 22 carbon atoms.
[0388] From the viewpoint that the resulting fiber products have good water repellency, lauryl phosphate and decyl phosphate are preferred.
[0389] Phosphate compounds can be commercially available products such as "PHOSPHANOL ML-200" (manufactured by Toho Chemical Industry Co., Ltd., trade name).
[0390] A pretreatment solution containing one or more of the compounds having the specific functional groups described above can be prepared as an aqueous solution of, for example, the aforementioned compounds. Additionally, the pretreatment solution may also contain acids, bases, surfactants, chelating agents, etc.
[0391] Methods for treating fibrous materials using the aforementioned pretreatment solution include, for example, padding, impregnation, spraying, and coating. For padding, methods using padding apparatuses described on pages 396-397 of the *Dictionary of Fiber Dyeing Processing* (Published by Nikkan Kogyo Shimbun, 1949) or pages 256-260 of *Color Dyeing Chemistry III* (Published by Jitsukyo Publishing Co., Ltd., 1975) can be cited. For coating, methods using coating machines described on pages 473-477 of the *Overview of Dyeing and Finishing Equipment* (Published by Kogyo Publishing Co., Ltd., 1956) can be cited. For impregnation, batch dyeing machines described on pages 196-247 of the *Overview of Dyeing and Finishing Equipment* (Published by Kogyo Publishing Co., Ltd., 1956) can be cited, including liquid dyeing machines, airflow dyeing machines, roller dyeing machines, skein dyeing machines, washing dyeing machines, and package dyeing machines. Examples of spray treatment methods include gas spraying, which uses compressed air to atomize the treatment liquid and then blows it out, and gas spraying using hydraulic atomization. The concentration of the treatment liquid and subsequent heat treatment conditions can be appropriately adjusted considering the purpose and performance. Furthermore, if the pretreatment liquid contains water, it is preferable to dry it after attaching it to the fibrous material to remove the water. There are no particular limitations on the drying method; either dry heat or wet heat methods are acceptable. There are also no particular limitations on the drying temperature; for example, drying can be performed at room temperature to 200°C for 10 seconds to several days. If necessary, a heat treatment at 100 to 180°C for approximately 10 seconds to 5 minutes can be performed after drying.
[0392] In addition, when the fiber material is a dyed product, the pretreatment with the pretreatment solution can be carried out before dyeing or in the same bath as dyeing. However, when performing reduction soaping, there is a risk that the adsorbed compounds with the above-mentioned specific functional groups (such as phenolic polymers) may be shed during the process. Therefore, it is preferable to perform the treatment after reduction soaping after dyeing.
[0393] The treatment temperature for immersion can be set to 60–130℃. The treatment time can be set to 5–60 minutes.
[0394] In the functional group introduction process using a pretreatment solution, it is preferable to treat the material with an amount of the compound having the aforementioned specific functional groups in a quantity of 1.0 to 7.0 parts by mass relative to 100 parts by mass of the fiber material. Within this range, a high level of both durable water repellency and texture can be achieved.
[0395] It is preferable to adjust the pH of the pretreatment solution to 3-5. pH adjustment can be achieved using pH adjusters such as acetic acid or malic acid.
[0396] In the pretreatment solution, salts can also be used to more effectively adsorb compounds with the aforementioned specific functional groups onto the fiber material through the salting-out effect. Examples of usable salts include sodium chloride, sodium carbonate, ammonium sulfate, and sodium sulfate.
[0397] In the functional group introduction process using a pretreatment solution, it is preferable to remove the over-treated compound containing the aforementioned specific functional groups. Washing with water is an example of such a removal method. By ensuring thorough removal, the obstruction of water repellency can be suppressed during subsequent water-repellent processing, and the texture of the resulting fiber product is improved. Furthermore, it is preferable that the obtained functional group-containing fiber is thoroughly dried before contacting the hydrocarbon-based water-repellent agent.
[0398] (ii) Examples of fibers in which the aforementioned specific functional groups are directly introduced into the materials constituting the fiber include, for example, cationic dyeable polyester (CD-PET).
[0399] From the viewpoint of improving the water repellency of the resulting fiber product, the surface zeta potential of functional group-containing fibers is preferably -100 to -0.1 mV, more preferably -50 to -1 mV. The surface zeta potential of the fiber can be measured, for example, using a zeta potential-particle size measurement system ELSZ-1000ZS (manufactured by Otsuka Electronics Co., Ltd.).
