Examples of the alkoxy group having 1 to 40 carbon atoms include a methoxy group, an ethoxy group, a propoxy group, and a butoxy group.
[0125] The silicone may have at least one long chain hydrocarbon group. For example, R 51 At least one of R 53 At least one of or R 51 and R 53 may be a long chain hydrocarbon group, and R 51At least one of (for example, one of) may be a long-chain hydrocarbon group. Here, the long-chain hydrocarbon group may be a saturated hydrocarbon group having 6 or more, 10 or more, 15 or more, or 20 or more, preferably 10 or more or 23 or more.

[0126] The long-chain hydrocarbon group R 51 and R 53 Other than R 51 and R 53 is preferably a hydrogen atom or a methyl group, and more preferably a methyl group.
[0127] a is an integer of equal to or greater than 0. In terms of ease of industrial production and availability, a may be equal to or less than 40, equal to or less than 30, or equal to or less than 20, and is preferably equal to or less than 30.
[0128] The sum of a and b is 5 to 200. From the viewpoints of ease of industrial production, availability, and handling, the sum of a and b is preferably 10 to 100, and more preferably 40 to 60. a may be 0 to 150, for example, 1 to 100. The lower limit of b may be 1, 2, or 3, and the upper limit of b may be 150, 10, or 5.
[0129] When a or b is 2 or more, R exists in plural. 51 and R 52 Each of may be the same or different.
[0130] R51 and R 53 Group (for example, R 51 and R 52 Groups and R 53 It is preferable that 50 mol % or more of the total of the alkyl groups) are methyl groups.
[0131] The order of the repeating units bounded by a or b is not limited to the order shown in the chemical formula, but may be any order, i.e., the silicone may be a random polymer or a block polymer.
[0132] For example, silicones may have the formula: (R 53 )3Si-O-[-Si(R 51 )2-O-] a -[-Si(R 51 )(R 52 )-O-] b -Si(R 53 )3(S2) [In the formula, R 51 each independently represents a hydrogen atom, an alkyl group having 1 to 40 carbon atoms, an aryl group having 6 to 40 carbon atoms, an alkoxy group having 1 to 40 carbon atoms, or a long-chain hydrocarbon group; R 52 each independently represents a long chain hydrocarbon group; R 53 each independently represents a hydrogen atom, an alkyl group having 1 to 40 carbon atoms, an aryl group having 6 to 40 carbon atoms, an alkoxy group having 1 to 40 carbon atoms, or a long-chain hydrocarbon group; a represents an integer of 0 or more, b represents an integer of 1 or more, and (a+b) is 5 to 200.

[0133] Examples of silicones are: [ka] [In the formula, a represents an integer of 0 to 150, b represents an integer from 1 to 150; (a+b) is 5 to 200; and n is an integer from 1 to 36 (preferably, n is a long-chain hydrocarbon group).
[0134] Silicone can be synthesized by a conventional method, for example, by subjecting silicone having a SiH group to a hydrosilylation reaction with an α-olefin.
[0135] Examples of silicones having a SiH group include methylhydrogensilicones having a degree of polymerization of 10 to 200, or copolymers of dimethylsiloxane and methylhydrogensiloxane. Among these, methylhydrogensilicones are preferred because they are easy to produce industrially and obtain. Hydrogensilicones (e.g., methylhydrogensilicones) are polydiorganosiloxanes in which a portion of the side chain is replaced with hydrogen, and the hydrogen atom is directly bonded to a silicon atom. When using hydrogensilicones, a catalyst may be used to improve reactivity. For example, zinc, tin, manganese, cobalt, iron, and amine-based catalysts can be used. As these catalysts, organic acid metal salts are preferred, and as organic acids, fatty acids are preferred. From the viewpoint of excellent handling, zinc stearate or the like can be used. It is preferable to use 10 to 40% of the catalyst relative to the methylhydrogensilicone, since the catalyst is more likely to exert its effect. Two or more of amino-modified, epoxy-modified, carboxy-modified, and methylhydrogensilicones may be mixed. All of them are silicones having reactive groups, and it is preferable that they are silicones having film-forming properties. The term "film-forming ability" refers to the ability of the silicone to form a solid film, rather than an oil or gel film, after it is attached to the fiber surface in an emulsion state.
[0136] α-Olefins are compounds from which long-chain hydrocarbon groups in silicones are derived. Specific examples of α-olefins are 1-tricosene, 1-tetracosene, 1-hexacosene, 1-octacosene, 1-triacontene, and 1-dotriacontene. The hydrosilylation reaction may be carried out by reacting the above-mentioned silicone having a SiH group with an α-olefin in a stepwise manner or all at once, if necessary in the presence of a catalyst.
[0137] The amounts of the SiH group-containing silicone and the α-olefin used in the hydrosilylation reaction can be appropriately selected depending on the SiH group equivalent or number average molecular weight of the SiH group-containing silicone, respectively.
[0138] Examples of catalysts used in the hydrosilylation reaction include platinum and palladium compounds, and among these, platinum compounds are preferred, such as platinum(IV) chloride.
[0139] The reaction conditions for the hydrosilylation reaction are not particularly limited and can be appropriately adjusted. The reaction temperature is, for example, 10 to 200° C., and preferably 50 to 150° C. The reaction time can be, for example, 3 to 12 hours when the reaction temperature is 50 to 150° C. The hydrosilylation reaction is preferably carried out under an inert gas atmosphere. Examples of the inert gas include nitrogen and argon. The reaction proceeds without a solvent, but a solvent may be used. Examples of the solvent include dioxane, methyl isobutyl ketone, toluene, xylene, and butyl acetate.
[0140] (Reactive Silicone) The silicone may include reactive silicone. Examples of reactive silicone include polysiloxanes having reactive groups at the side chain, one end, both ends, or at the side chain and both ends. From the viewpoint of excellent slip resistance and excellent water repellency at the same time, polysiloxanes having reactive groups at the side chain and / or both ends may be used. The reactive silicone is not particularly limited as long as it has a reactive group in the molecule, and examples thereof include amino-modified silicone, epoxy-modified silicone, carboxy-modified silicone, and hydrogen-modified silicone. The reactive silicone may be one in which one or more substituents in the above formula (S1) or formula (S2) are replaced with reactive groups.

[0150] The production method of hydrolyzing a silane compound in water will be described in detail. As a raw material for production, any silane compound can be used as long as the type of hydrolyzable group is chloro or alkoxy, the compound contains one, three or four hydrolyzable groups, and the compound has an alkyl group that satisfies the above conditions.Specifically, tetrachlorosilane, tetramethoxysilane, tetraethoxysilane, tetrabutoxysilane, methyltrichlorosilane, methyltrimethoxysilane, methyltriethoxysilane, methyltriisopropoxysilane, methyltributoxysilane, ethyltrichlorosilane, ethyltrimethoxysilane, ethyltriethoxysilane, propyltrichlorosilane, propyltrimethoxysilane, propyltriethoxysilane, isopropyltrichlorosilane, isopropyltrimethoxysilane, isopropyltriethoxysilane, butyltrichlorosilane, Trichlorosilane, butyltrimethoxysilane, butyltriethoxysilane, isobutyltrichlorosilane, isobutyltrimethoxysilane, isobutyltriethoxysilane, hexyltrichlorosilane, hexyltrimethoxysilane, hexyltriethoxysilane, 2-ethylhexyltrichlorosilane, 2-ethylhexyltrimethoxysilane, 2-ethylhexyltriethoxysilane, decyltrichlorosilane, decyltrimethoxysilane, decyltriethoxysilane, cetyltrichlorosilane, cetyltrimethoxysilane, cetyltriethoxy Silane, stearyl trichlorosilane, stearyl trimethoxysilane, stearyl triethoxysilane, trimethyl chlorosilane, trimethyl methoxysilane, trimethyl ethoxysilane, trimethyl isopropoxysilane, dimethyl ethyl chlorosilane, dimethyl ethyl methoxysilane, dimethyl ethyl ethoxysilane, dimethyl propyl chlorosilane, dimethyl propyl methoxysilane, dimethyl propyl ethoxysilane, dimethyl isopropyl chlorosilane, dimethyl isopropyl methoxysilane, dimethyl isopropyl ethoxysilane, di Usable silane compounds include, but are not limited to, methylhexyl chlorosilane, dimethylhexyl methoxysilane, dimethylhexyl ethoxysilane, dimethyldecyl chlorosilane, dimethyldecyl methoxysilane, dimethyldecyl ethoxysilane, dimethylcetyl chlorosilane, dimethylcetyl methoxysilane, dimethylcetyl ethoxysilane, dimethylstearyl chlorosilane, dimethylstearyl methoxysilane, dimethylstearyl ethoxysilane, and partial hydrolysates thereof.From the viewpoints of operability, ease of distilling off by-products, and ease of obtaining raw materials, it is more preferable to use methoxysilane or ethoxysilane. One or a mixture of two or more of these silane compounds may be used.
[0151] As a method for hydrolyzing a silane compound in water, a commonly known method can be used, such as a method in which the hydrolysis reaction is carried out while dropping the silane compound into water, or a method in which water and the silane compound are mixed together and then the hydrolysis reaction is carried out. A hydrolysis catalyst may be used when carrying out the hydrolysis reaction. As the hydrolysis catalyst, a conventionally known catalyst may be used, and it is preferable to use an acidic or alkaline one. In the case of an acidic catalyst, a solid acid such as hydrogen halide, carboxylic acid, sulfonic acid, acidic or weakly acidic inorganic salt, or ion exchange resin is preferable.

The amount of the catalyst to be added is preferably adjusted so that the pH of the aqueous solution is 2 to 7 or 7 to 12. After the reaction is completed, a neutralizing agent for neutralizing the acidic or alkaline catalyst may be added as necessary.
[0152] A surfactant may be added to the aqueous solution in order to disperse the silane compound and the hydrolysis reaction product in water. There is no particular limitation on the surfactant, but for example, anionic surfactants such as alkyl sulfates, alkylbenzene sulfonates, and alkyl phosphates, nonionic surfactants such as polyoxyethylene alkyl ethers, polyoxyethylene oxypropylene alkyl ethers, polyoxyethylene alkyl phenyl ethers, and polyoxyethylene fatty acid esters, cationic surfactants such as quaternary ammonium salts and alkylamine acetates, and amphoteric surfactants such as alkyl betaines and alkyl imidazolines can be used alone or in combination of two or more.

There is no particular limitation on the amount of surfactant added, but it is preferably 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 is not sufficiently obtained, and if the amount is more than 50 parts by weight, the water repellency of the water repellent agent may be impaired.
[0153] A hydrolysis catalyst and a surfactant may be added to the mixture of water and the silane compound as necessary, and the hydrolysis reaction may be carried out at 0 to 90°C for 10 minutes to 24 hours. Silicone resin can be obtained by subsequently carrying out a neutralization reaction as necessary. In addition, alcohols and neutralized salts produced as by-products in the hydrolysis reaction can be removed by vacuum distillation, filtration, or the like. Various additives can be added to this silicone resin. For example, preservatives, thickeners, and the like can be added depending on the purpose.

[0233] The reactive emulsifier is an emulsifying dispersant having radical reactivity, that is, an emulsifier having one or more polymerizable unsaturated groups in the molecule, and is copolymerizable with the above-mentioned monomer. Examples of the reactive emulsifier include the reactive emulsifiers described in JP 2017-25440 A, and preferably the reactive emulsifier represented by the following formula: [ka]
[0234] In the above formula, R 10 represents an organic residue having an ethylenically unsaturated double bond group having 12 to 20 carbon atoms.
[0235] R 11 represents an oxyalkylene group having 2 to 10 carbon atoms, and preferably represents an oxyethylene group.
[0236] When the reactive emulsifier is a reactive emulsifier represented by the above formula, the product stability of the aqueous dispersion (repellent composition) is improved without decreasing the water repellency. As the reactive emulsifier represented by the above formula, preferably, polyoxyethylene alkylphenol and the like are used.
[0237] The emulsifiers can be used alone or in combination of two or more kinds.
[0238] The mixing ratio of the emulsifier may be, for example, 5 parts by weight or more and, for example, 18 parts by weight or less, relative to 100 parts by weight of the total amount of the monomers.
[0239] The mixing ratio of the emulsifier may be, for example, 8 parts by weight or more and, for example, 20 parts by weight or less, relative to 100 parts by weight in total of the isocyanate derivative (B) and the non-fluorinated copolymer (A).
[0240] The blending ratio of the emulsifier may be, for example, 0.5% by weight or more and, for example, 5% by weight or less, relative to the water repellent composition.
[0241] After the above-mentioned components are mixed, the mixture is stirred and ultrasonic waves are applied to the mixture to emulsify it.
[0242] As a method for stirring, for example, a dispersing machine such as a homomixer, an ultrasonic homogenizer, a pressure homogenizer, a milder, or a porous membrane press-in dispersing machine is used, and preferably a homomixer is used.
[0243] The stirring conditions are appropriately set, and when a homomixer is used, the rotation speed is set to, for example, 500 rpm or more and, for example, 10,000 rpm or less. The stirring time is, for example, 0.5 minutes or more and, for example, 10 minutes or less, preferably 5 minutes or less. The stirring temperature is, for example, 50°C or more and, for example, 90°C or less.
[0244] Next, in the case where a portion of the monomers was blended when the above-mentioned mixed liquid was prepared, the remainder of the above-mentioned monomers is blended into this mixed liquid.
[0245] Next, a polymerization initiator is added to this mixture.
[0246] Examples of the polymerization initiator include azo compounds such as azobisisobutylamidine dihydrochloride and azobisisobutyronitrile; water-soluble polymerization initiators such as persulfates such as potassium persulfate and ammonium persulfate; and oil-soluble polymerization initiators such as organic peroxides such as benzoyl peroxide, di-t-butyl peroxide, lauryl peroxide, cumene hydroperoxide, t-butyl peroxypivalate and diisopropyl peroxydicarbonate. Preferably, the azo compounds are used. More preferably, the azobisisobutyronitrile is used.
[0247] The mixing ratio of the polymerization initiator may be, for example, 0.01 parts by weight or more, and for example, 10 parts by weight or less, relative to 100 parts by weight of the monomer.
[0248] If necessary, a chain transfer agent can be added to this mixture.
[0249] Examples of the chain transfer agent include mercaptan group-containing compounds such as lauryl mercaptan, thioglycol, and thioglycerol (particularly alkyl mercaptans (e.g., having 1 to 30 carbon atoms)), inorganic salts such as sodium hypophosphite and sodium hydrogen sulfite, and preferably lauryl mercaptan.
[0250] The mixing ratio of the chain transfer agent may be, for example, 0.01 parts by weight or more and, for example, 10 parts by weight or less, relative to 100 parts by weight of the monomer.
[0251] Then, this mixture is heated to polymerize the monomers.
[0252] The heating conditions are such that the heating temperature is, for example, 40° C. or higher and, for example, 80° C. or lower, and the heating time is, for example, 1 hour or higher and, for example, 6 hours or lower. As a result, an emulsion of the non-fluorinated copolymer (A) is obtained, and a water repellent composition containing the isocyanate derivative (B) and the non-fluorinated copolymer (A) (emulsion) is obtained.
[0253] In the first method, the monomers constituting the non-fluorinated copolymer (A) are polymerized in the presence of the isocyanate derivative (B), but the isocyanate derivative (B) can also be blended after the monomers have been polymerized (second method). Also, the isocyanate derivative (B) can be blended after the monomers have been polymerized in the presence of a surfactant and a liquid medium (third method).
[0254] The third method is the same as the above-mentioned production method, except that the monomers constituting the above-mentioned non-fluorinated copolymer (A) are polymerized in the absence of the isocyanate derivative (B). The non-fluorinated copolymer (A) obtained by the third method can be combined with the isocyanate derivative (B) to obtain the water-repellent composition of the present disclosure.
[0255] Alternatively, a monomer may be polymerized to prepare a non-fluorinated copolymer (A), and then the obtained non-fluorinated copolymer (A) may be blended with an isocyanate derivative (B) (fourth method). Alternatively, a monomer may be polymerized to prepare a non-fluorinated copolymer (A), and then the obtained non-fluorinated copolymer (A) may be blended with an isocyanate derivative (B), a surfactant and a liquid medium (fifth method).
[0256] In the fourth and fifth methods, examples of the polymerization method include solution polymerization, suspension polymerization, and emulsion polymerization.
[0257] When solution polymerization is employed, the monomers are dissolved in an organic solvent in the presence of the above-mentioned polymerization initiator, and the resulting solution is heated with stirring after replacing the atmosphere with nitrogen.
[0258] The polymerization initiator may be any of the above-mentioned polymerization initiators. The mixing ratio of the polymerization initiator may be, for example, 0.01 parts by weight or more and, for example, 20 parts by weight or less, preferably 10 parts by weight or less, based on 100 parts by weight of the monomer.
[0259] Examples of the organic solvent include the solvents listed in the liquid medium described above. The organic solvent may be, for example, glycol (e.g., glycol having 2 to 40 carbon atoms, specifically, ethylene glycol, propylene glycol, etc.), ester (e.g., ester having 2 to 40 carbon atoms, specifically, ethyl acetate, butyl acetate), ketone (e.g., ketone having 2 to 40 carbon atoms, specifically, methyl ethyl ketone, diisobutyl ketone, methyl isobutyl ketone), alcohol (e.g., alcohol having 1 to 40 carbon atoms, specifically, ethanol, butanol, isopropyl alcohol). As the organic solvent, a water-soluble glycol-based solvent (e.g., ethylene glycol, propylene glycol, etc.) may be preferably used.
[0260] The mixing ratio of the organic solvent may be, for example, 10 parts by weight or more, preferably 50 parts by weight or more, and for example, 2000 parts by weight or less, preferably 1000 parts by weight or less, relative to 100 parts by weight of the monomer.
[0261] Regarding the heating conditions, the heating temperature may be, for example, 30° C. or higher and, for example, 120° C. or lower, and the heating time may be, for example, 1 hour or higher and, for example, 10 hours or lower.
[0262] In this manner, the fluorine-free copolymer (A) is obtained.
[0263] After producing the non-fluorinated copolymer (A) by solution polymerization, the organic solvent is removed, and the non-fluorinated copolymer (A) is blended together with the isocyanate derivative (B) with a surfactant and a liquid medium to prepare an emulsion of the non-fluorinated copolymer (A).
[0264] <Uses of the water repellent composition> Examples of applications of the water repellent composition in the present disclosure include an external treatment agent (surface treatment agent) or an internal treatment agent, a repellent (a water repellent, an oil repellent, or a water and oil repellent, particularly a water repellent), an antifouling agent, a soil release agent, a stripping agent, a release agent (an external release agent or an internal release agent), and the like.
[0265] <Manufacturing method of treated products> A method of making a treatment product according to the present disclosure includes applying a water repellent composition according to the present disclosure to a substrate, particularly a fibrous substrate.
[0266] [Processing products] Examples of substrates treated with the water repellent composition of the present disclosure include textile products, 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, bricks, cement, metals and oxides, ceramic products, plastics, painted surfaces, and plasters. Examples of textile products include various types of natural fibers from animals and plants, 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 mixed fibers thereof. As an example of a substrate to be treated with the water repellent composition, an example of a woven or knitted fabric will be described in detail.
[0267] (Woven and knitted fabrics) ·Method of manufacturing knitted fabrics The woven or knitted fabric can be obtained by weaving or knitting the mixed and intertwined yarn to obtain a green fabric, and then post-processing and water-repellent processing the same. The weaving or knitting can be performed using a known weaving machine or knitting machine, and the preparation process prior to the weaving or knitting can also be performed using known equipment.
[0268] In the post-processing, the grey fabric is first scoured and relaxed. Scouring and relaxation can be carried out at a temperature of 80 to 130°C by a continuous or batch method. Usually, it is preferable to carry out the scour and relaxation by a batch method at 100°C or less, and it is particularly preferable to carry out the scour and relaxation using a high-pressure liquid jet dyeing machine equipped with a jet nozzle.
[0269] After scouring and relaxing, the woven or knitted fabric is preset. Presetting is usually done by dry heat treatment at 170-200℃ for 30-120 seconds using a pin tenter. After presetting, the fabric is dyed according to the usual method, and then a final setting is performed if necessary.
[0270] After the post-processing, the woven or knitted fabric may be subjected to a water-repellent treatment. In the water-repellent treatment, first, an aqueous solution containing a water repellent (which may be the water repellent composition of the present disclosure) is prepared. Next, the aqueous solution is applied to the woven or knitted fabric after the post-processing based on a padding method, a spray method, a kiss roll coater method, a slit coater method, or the like, and then a dry heat treatment is performed at 105 to 190°C for 30 to 150 seconds. The aqueous solution may also contain a crosslinking agent, a softener, an antistatic agent, or the like as necessary. After the water-repellent treatment, the woven or knitted fabric may be calendered to further improve the water-repellent performance.
[0271] The woven and knitted fabrics are suitably used for clothing applications, particularly for uniform wear, ladies' wear, and sportswear.
[0272] Laminated fabric The woven or knitted fabric of the present disclosure may be provided as a laminated fabric having a moisture-permeable waterproof layer on one side thereof. The moisture-permeable waterproof layer may be laminated directly onto the woven or knitted fabric, or may be laminated onto the woven or knitted fabric via an adhesive layer. When the laminated fabric of the present disclosure is used for clothing or the like, it is arranged so that the woven or knitted fabric side is exposed to rainwater or the like.
[0273] Breathable waterproof layer The moisture-permeable waterproof layer is a layer that covers one side of the woven or knitted fabric and is made of a resin that has waterproof and moisture-permeable properties.
[0274] The moisture-permeable waterproof layer may be formed by applying a resin (resin constituting the moisture-permeable waterproof layer) directly to the woven or knitted fabric, or may be laminated on one side of the woven or knitted fabric via an adhesive layer described later. In the present disclosure, a mixed fiber intertwined yarn having fine protrusions due to loops or slack is used in the woven or knitted fabric. Therefore, the protrusions are firmly entangled with the adhesive layer or the moisture-permeable waterproof layer, and an anchor effect is exerted, making it even more difficult for the woven or knitted fabric and the moisture-permeable waterproof layer to peel off. When a normal woven or knitted fabric (a woven or knitted fabric in which the above-mentioned protrusions are not sufficiently maintained on the surface) is used, the anchor effect may not be exerted sufficiently, and in such a case, the woven or knitted fabric and the moisture-permeable waterproof layer tend to peel off easily.
[0275] The resin constituting the moisture-permeable waterproof layer is not particularly limited, but is preferably composed of polyurethane resin as the main component, and for example, it is preferable that the polyurethane resin is contained in a proportion of 80% by weight or more. Polyurethane resin is generally suitable for forming a resin layer having moisture permeability and waterproofness. Among them, a microporous type is preferable in consideration of moisture permeability, but in cases where it is expected that the layer will be exposed to rain for a long period of time or will be used repeatedly by washing, etc., a non-porous type moisture-permeable urethane may be used instead of a microporous type.
[0276] As the polyurethane resin, a conventionally known resin obtained by reacting a polyisocyanate component with a polyol component can be used.
[0277] The moisture-permeable waterproof layer may have a microporous structure or a non-porous structure. When the moisture-permeable waterproof layer has a microporous structure, the moisture-permeable waterproof layer may contain inorganic fine powder in order to ensure the desired moisture permeability.
[0278] Examples of inorganic fine powders include fine powders made of silicon dioxide, aluminum dioxide, titanium dioxide, etc. The average primary particle size of the inorganic fine powder is preferably about 7 to 40 nm. The amount of the inorganic fine powder is preferably 3 to 50% by weight, more preferably 5 to 50% by weight, based on the total weight of the moisture-permeable waterproof layer.
[0279] The moisture-permeable waterproof layer has a thickness of preferably 5 μm or more, more preferably 10 to 30 μm. When the thickness is within the above range, the waterproof property and moisture permeability are well balanced, and further, there are advantages in terms of texture and tear strength.
[0280] ·Adhesive layer The laminated fabric preferably includes an adhesive layer. In other words, the woven / knitted fabric and the moisture-permeable waterproof layer are preferably laminated via an adhesive layer. The reason for this is described below. In the present disclosure, as described above, the woven / knitted fabric has fine protrusions on the surface due to loops or slack. Therefore, the protrusions are firmly entangled with the adhesive layer, and an anchor effect is exerted, making it even more difficult for the woven / knitted fabric and the moisture-permeable waterproof layer to peel off from each other.
[0281] In addition, when a moisture-permeable waterproof layer is directly laminated to the above-mentioned woven or knitted fabric, for example, by a coating method, the protrusions on the surface of the woven or knitted fabric may penetrate the moisture-permeable waterproof layer, resulting in pinholes and poor water resistance and strength. There is also a concern that the coating may not be uniform, resulting in uneven thickness of the moisture-permeable waterproof layer. In order to prevent this, for example, if the surface of the woven or knitted fabric is smoothed by calendaring, the protrusions or air retaining layer may be reduced, resulting in a decrease in water repellency. Therefore, in the present disclosure, it is preferable that the woven or knitted fabric and the moisture-permeable waterproof layer are laminated via an adhesive layer.
[0282] The type of adhesive constituting the adhesive layer is not particularly limited, but it is preferable that it has excellent compatibility with the moisture-permeable waterproof layer. For example, when a resin mainly composed of polyurethane resin is selected as the resin constituting the moisture-permeable waterproof layer, it is preferable to adopt an adhesive layer made of a polyurethane-based adhesive. The polyurethane-based adhesive may be of any structure such as ether-based, ester-based, or polycarbonate-based, but from the viewpoint of imparting excellent moisture permeability, an ether-based adhesive is preferable.
[0283] The adhesive layer may be formed over the entire surface of one side of the woven or knitted fabric, or may be formed in a pattern from the viewpoint of moisture permeability, texture, etc. The shape of the pattern is not particularly limited, but examples include dots, lines, a lattice, a checkered pattern, a tortoiseshell pattern, etc., and it is preferable that any of these patterns are uniformly arranged over the entire surface.
[0284] The thickness of the adhesive layer is preferably about 10 to 100 μm, more preferably 20 to 80 μm. If 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, and if it exceeds 100 μm, the manufacturing cost increases and further adhesiveness cannot be expected, so neither is preferable.
[0285] · Lining fabric In the laminated fabric of the present disclosure, a fiber fabric for lining may be laminated on the moisture-permeable waterproof layer (the surface of the moisture-permeable waterproof layer opposite to the surface on which the woven / knitted fabric of the present disclosure is laminated). The fiber fabric for lining can protect the moisture-permeable waterproof layer, and can provide even better waterproofness (water pressure resistance) and strength. In addition, laminating the fiber fabric for lining can suppress the elongation of the laminated fabric as a whole, and therefore it is possible to suppress the reduction of the protruding parts of the mixed fiber composite yarn as a result of the protruding parts being pulled by the elongation of the woven / knitted fabric due to the finishing process after lamination or tension during wearing, etc., and the above-mentioned water repellency can be maintained at a higher level. Furthermore, laminating the fiber fabric for lining can further improve the water repellency.
[0286] Examples of fiber fabrics for lining include various woven fabrics and knitted fabrics. Among them, knitted fabrics are preferred because, compared with woven fabrics, the constituent yarns are more likely to protrude from the surface and the surface is not flat, and the anchor effect is more pronounced, making it less likely to peel off from the moisture-permeable waterproof layer. In particular, tricot knitted fabrics are preferred because they have less stretchability than knitted fabrics with other structures, so the stitch gaps do not become too large and water repellency can be more effectively expressed. In addition, tricot knitted fabrics are also preferred because they can obtain a long grey fabric during knitting, have few seams, and can be evenly layered on the moisture-permeable waterproof layer.
[0287] The material of the fiber constituting the lining fiber fabric is not particularly limited and can be selected as appropriate, but nylon fiber is preferable. This is because acid dyes are generally used in nylon fibers, and migration and sublimation of disperse dyes to the moisture-permeable waterproof layer, which is a problem in polyester fibers and the like that use disperse dyes, is unlikely to occur. The form (long fiber, short fiber, or spun yarn) or fineness of the fiber constituting the lining fiber fabric is not particularly limited and can be selected as appropriate within a range that does not impair the effects of the present disclosure.
[0288] Laminated fabric properties The laminated fabric has excellent waterproofness. A suitable example of the waterproofness of the laminated fabric of the present disclosure is, for example, a water level measured according to the water resistance test specified in JIS L 1092:2009 A method (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 the water level is not particularly limited, and may be, for example, 50,000 mm or 25,000 mm.
[0289] The laminated fabric has excellent moisture permeability. A suitable example of the moisture permeability of the laminated fabric of the present disclosure is a moisture permeability of, for example, 10,000 g / m2 as measured according to JIS L 1099:2012 B-1 method (potassium acetate method). 2 24h or more, preferably 15000g / m 2 24h or more, more preferably 20,000g / m 2 The upper limit of the moisture permeability is not particularly limited, but is, for example, 40,000 g / m 2 24h or 35,000g / m 2 ·24h·mm are examples.
[0290] In the laminated fabric, interlayer peeling between the woven or knitted fabric and the moisture-permeable waterproof layer is suppressed. In the laminated fabric of the present disclosure, a suitable example of the peel strength between the woven or knitted fabric and the moisture-permeable waterproof layer is, for example, 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, as measured according to the method of JIS L 1089. In order to set the peel strength within the above range, for example, a woven or knitted fabric that has not been subjected to calendaring may be used, or an adhesive layer may be provided.
[0291] ·Laminated fabric manufacturing method The method for producing the laminated fabric is not particularly limited, and examples thereof include the first and second production methods described below. First manufacturing method: The first manufacturing method includes a step of forming the moisture-permeable waterproof layer by applying a resin that constitutes the moisture-permeable waterproof layer to the surface of a woven or knitted fabric. Second manufacturing method: The second manufacturing method includes a step of forming an adhesive layer on the woven or knitted fabric or the moisture-permeable waterproof layer, and a step of bonding the woven or knitted fabric and the moisture-permeable waterproof layer via the adhesive layer.
[0292] It is preferable that the woven or knitted fabric used in the laminated fabric (i.e., the woven or knitted fabric of the present disclosure described above) maintains the protrusions on the fabric surface as much as possible. For example, when the woven or knitted fabric is subjected to a calendar process to facilitate coating processing or the like, the fine protrusions of the mixed fiber intertwined yarn are crushed to form a flat surface, and a specific water drop rolling angle may not be achieved. Furthermore, when the calendar process is performed, the above air retention layer may not be sufficiently maintained, and the desired water repellency may not be achieved. Therefore, it is preferable to thoroughly consider the conditions of the calendar process. For example, when the woven or knitted fabric is subjected to a calendar process, normal conditions (for example, a temperature of 130° C. or higher and a linear pressure of 200 to 20,000 N / cm) that do not reduce the protrusions of the mixed fiber intertwined yarn too much may be adopted. The calendar process may be performed without heating.
[0293] In the first manufacturing method, the resin constituting the moisture-permeable waterproof layer can be applied to the surface of the woven or knitted fabric by, for example, a coating method. In the coating method, a knife coater or a comma coater can be used. From the viewpoint of providing excellent moisture permeability, it is preferable to obtain the moisture-permeable waterproof layer by a wet method.
[0294] In the second manufacturing method, the adhesive layer can be formed on the woven or knitted fabric or the moisture-permeable waterproof layer by, for example, lamination. In the lamination method, the adhesive layer can be formed by a method using a resin solution or a hot melt method. First, a moisture-permeable waterproof layer-forming resin composition (e.g., a resin composition containing a resin and an organic solvent) is applied to the surface of a release material (such as release paper, release cloth, or release film) with a clearance, and a moisture-permeable waterproof layer is formed while adjusting the thickness, and then heat-treated to completely react to obtain a film. The release material can be appropriately removed after lamination or aging.
[0295] Then, an adhesive layer is formed on the woven or knitted fabric or the moisture-permeable waterproof layer. For example, in the case of a method using a resin solution, a two-component curing polyurethane resin solution adjusted to a viscosity in the range of 500 to 5000 mPa·s may be applied over the entire surface or in a pattern. The adhesive layer is then dried to form an adhesive layer, and the woven or knitted fabric and the moisture-permeable waterproof layer are bonded together via the adhesive layer, and the two are pressure-bonded or thermo-press-bonded to each other, thereby completing the second manufacturing method.
[0296] 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 it is more preferable for practical use to use one that melts at a temperature range of about 80 to 150 ° C. In this case, first, the hot melt resin is melted while taking into consideration the melting point of the resin and the viscosity when melted. Then, the molten resin is applied onto the woven or knitted fabric or the moisture-permeable waterproof layer, and is matured while cooling at room temperature to form an adhesive layer. Then, the woven or knitted fabric and the moisture-permeable waterproof layer are bonded together via the adhesive layer and pressed together to carry out the second manufacturing method.
[0297] In the manufacturing method, it is preferable to adopt the second manufacturing method. When the moisture-permeable waterproof layer is laminated using a coating method, there is a concern that pinholes will occur in the moisture-permeable waterproof layer due to fine protrusions on the surface of the woven or knitted fabric, and the water pressure resistance will tend to decrease. In addition, when the woven or knitted fabric is subjected to a calendaring process in an attempt to form a uniform moisture-permeable waterproof layer, there is a concern that the protrusions or air retaining layer will be reduced and the desired water repellency will not be achieved, and since a separate examination of the calendaring conditions is required, the process itself may become complicated.
[0298] Thereafter, a fiber fabric for the lining can be laminated onto the moisture-permeable waterproof layer using any suitable known method.
[0299] ·Applications of laminated fabric The laminated fabric has excellent water repellency and moisture-permeable waterproof properties, and the moisture-permeable waterproof layer does not peel off even in harsh environments, so it is suitable for use in fields such as uniform clothing, sports clothing, and outdoor products used outdoors.
[0300] [Processing method] The water repellent composition of the present disclosure can be applied to a substrate as a treatment agent (particularly a surface treatment agent) by a conventionally known method. The water repellent composition of the present disclosure may be dispersed and diluted in an organic solvent or water as necessary, and attached to the surface of a substrate by a known method such as dip coating, spray coating, foam coating, etc., and then dried. After drying, a textile product to which the solid components of the water repellent composition are attached is obtained. If necessary, it may be applied together with a suitable crosslinking agent and cured. Furthermore, it is also possible to use the water repellent composition of the present disclosure in combination with various additives such as water and / or oil repellents, antislip agents, antistatic agents, texture adjusters, softeners, antibacterial agents, flame retardants, paint fixing agents, anti-wrinkle agents, drying speed adjusters, crosslinking agents, film-forming assistants, compatibilizers, antifreeze agents, viscosity adjusters, ultraviolet absorbers, antioxidants, pH adjusters, insect repellents, and defoamers. Examples of various additives may be the same as those described in the "other components" of the water repellent composition described above. The concentration of the non-fluorinated copolymer (A) in the treating agent to be contacted with the substrate may be appropriately changed depending on the application, but may be 0.01 to 10% by weight, for example 0.05 to 5% by weight.
[0301] [Textile products] There are various examples of textile products that serve as substrates, such as cloth products and paper products. Textile products that serve as substrates are also called fiber substrates.
[0302] Examples of textile products include natural fibers of animal and vegetable origin such as cotton, hemp, wool, silk, etc., synthetic fibers such as polyamide, polyester, polyvinyl alcohol, polyacrylonitrile, polyvinyl chloride, polypropylene, etc., semi-synthetic fibers such as rayon, acetate, etc., inorganic fibers such as glass fiber, carbon fiber, asbestos fiber, etc., or mixtures of these fibers.

[0303] Examples of paper products include paper made of bleached or unbleached chemical pulp such as kraft pulp or sulfite pulp, bleached or unbleached high-yield pulp such as groundwood pulp, mechanical pulp or thermomechanical pulp, waste paper pulp such as recycled newsprint, recycled magazine paper, recycled corrugated cardboard or deinked recycled paper, paper containers, paper molded articles, etc. Specific examples of paper products include food packaging paper, gypsum board base paper, coated base paper, medium quality paper, general liners and cores, neutral pure white roll paper, neutral liners, rust-proof liners and metal interleaving paper, kraft paper, neutral printing and writing paper, neutral coated base paper, neutral PPC paper, neutral thermal paper, neutral pressure-sensitive base paper, neutral inkjet paper and neutral information paper, molded paper (molded containers), etc.
[0304] The water repellent composition can be applied to the textile by any of the methods known for treating textiles (e.g., fabrics) with liquids. The textile may be immersed in the water repellent composition, or the solution may be applied or sprayed onto the textile. The treated textile is preferably dried and cured by heating to develop water repellency. The heating temperature may be, for example, 100°C to 200°C, 100°C to 170°C, or 100°C to 120°C. In the present disclosure, good performance can be obtained even with low-temperature heating (e.g., 100°C to 140°C). In the present disclosure, the heating time may be 5 seconds to 60 minutes, for example, 30 seconds to 3 minutes.
[0305] Alternatively, the water repellent composition may be applied to the textile by a cleaning method, such as by laundering or by a dry cleaning method.
[0306] The textile products to be treated may be fabrics, including woven, knitted and nonwoven fabrics, apparel fabrics and carpets, but may also be fibers or yarns or intermediate textile products (e.g., slivers or rovings, etc.). The water repellent compositions of the present disclosure are particularly effective in rendering textile products (e.g., synthetic fibers) water repellent.
[0307] The fibers constituting the textile product may be natural fibers, synthetic fibers, semi-synthetic fibers, regenerated fibers or inorganic fibers. The fibers may be used alone or in combination of two or more kinds.
[0308] Examples of natural fibers include cotton, flax, cellulosic fibers such as pulp, chitin, chitosan, wool, and silk. Specific examples of wood pulp include mechanical pulps such as ground wood pulp (GP), pressure-risen ground wood 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), waste paper pulps such as deinking pulp (DIP) and waste pulp (WP), and semi-chemical pulps (CP).

[0335] As the phosphate ester compound, phosphate monoesters, diesters and triesters, in which the alkyl ester moiety is an alkyl group having 1 to 22 carbon atoms, and mixtures thereof can be used.
[0336] From the viewpoint of improving the water repellency of the resulting textile product, it is preferable to use lauryl phosphate and decyl phosphate.
[0337] As the phosphate ester compound, for example, a commercially available product such as "Phosphanol ML-200" (product name, manufactured by Toho Chemical Industry Co., Ltd.) can be used.
[0338] The pretreatment liquid containing one or more compounds having the specific functional group may be, for example, an aqueous solution of the above-mentioned compounds. The pretreatment liquid may also contain an acid, an alkali, a surfactant, a chelating agent, etc.
[0339] Examples of the method for treating the textile material with the pretreatment liquid include padding, immersion, spraying, and coating. Examples of padding include a method using a padding device described on pages 396-397 of Textile Dyeing and Processing Dictionary (published by Nikkan Kogyo Shimbun, 1963) and pages 256-260 of Color Dyeing Chemistry III (published by Jikkyo Publishing Co., Ltd., 1975).

Examples of the spray treatment include an air spray in which the treatment liquid is sprayed in the form of a mist using compressed air, and a method using an air spray of a liquid pressure atomization type. The treatment conditions, such as the concentration of the treatment liquid and the heat treatment after application, can be appropriately adjusted in consideration of various conditions such as the purpose and performance. In addition, when the pretreatment liquid contains water, it is preferable to dry the pretreatment liquid after it is applied to the fiber material in order to remove the water. There is no particular limit to the drying method, and either a dry heat method or a wet heat method may be used. There is also no particular limit to the drying temperature, and for example, drying may be performed at room temperature to 200°C for 10 seconds to several days. If necessary, heat treatment may be performed at a temperature of 100 to 180°C for about 10 seconds to 5 minutes after drying.
[0340] When the textile material is to be dyed, the treatment with the pretreatment liquid may be carried out before dyeing or in the same bath as the dyeing. However, when reduction soaping is carried out, there is a risk that the compound having the specific functional group (e.g., a phenolic polymer compound, etc.) adsorbed during the process may fall off, so it is preferable to carry out the treatment after reduction soaping after dyeing.
[0341] The treatment temperature in the immersion treatment can be 60 to 130° C. The treatment time can be 5 to 60 minutes.
[0342] In the functional group introduction step using a pretreatment liquid, the amount of the compound having the specific functional group attached is preferably 1.0 to 7.0 parts by weight per 100 parts by weight of the textile material.

[0344] In the pretreatment solution, a salt may be used in combination in order to effectively adsorb the compound having the specific functional group to the fiber material by the salting-out effect. Examples of the salt that can be used include sodium chloride. Examples of suitable salts include sodium carbonate, ammonium sulfate, and sodium sulfate.
[0345] In the functional group introduction step using the pretreatment liquid, it is preferable to remove the compound having the specific functional group that has been treated in excess. An example of a removal method is washing with water. By removing the compound sufficiently, it is possible to prevent the development of water repellency in the subsequent water repellent treatment from being hindered, and in addition, the feel of the resulting textile product is improved. In addition, it is preferable to thoroughly dry the resulting functional group-containing fiber before contacting it with a hydrocarbon-based water repellent.
[0346] (ii) An example of a fiber in which the specific functional group is directly introduced into the material constituting the fiber is cationic dyeable polyester (CD-PET).
[0347] From the viewpoint of improving the water repellency of the resulting textile product, the functional group-containing fiber preferably has a surface zeta potential of −100 to −0.1 mV, more preferably −50 to −1 mV. The zeta potential of the fiber surface can be measured, for example, by a zeta potential / particle size measuring system ELSZ-1000ZS (manufactured by Otsuka Electronics Co., Ltd.).
