[0020] The liquid-repellent compound of the present disclosure is a compound obtained by reacting compound (a) with compound (b), and has a portion derived from compound (a) and a portion derived from compound (b).

[0021] Specifically, the reactive group of compound (a) reacts with the reactive group of compound (b) to form the liquid-repellent compound of the present disclosure having a portion derived from compound (a) and a portion derived from compound (b).

[0022] Between the portion derived from compound (a) and the portion derived from compound (b), an organic group is formed by the reaction between the reactive group of compound (a) and the reactive group of compound (b). Such an organic group may be at least one selected from the group consisting of an amide group, a urea group, an ester group, and a urethane group.

When the liquid-repellent compound has an HD contact angle equal to or greater than the above lower limit, it can impart good liquid repellency (especially oil repellency) to the substrate. The HD contact angle is the static contact angle of the liquid-repellent compound with a spin-coated film, and is obtained by dropping 2 μL of HD onto the spin-coated film at room temperature (25° C.) and measuring the contact angle 1 second after the drop has landed.

[0031] The water contact angle of the liquid-repellent compound may be 35° or more, 40° or more, 45° or more, 50° or more, 55° or more, 65° or more, 75° or more, 85° or more, 90° or more, or 100° or more, and may be 160° or less, 140° or less, 130° or less, 120° or less, 110° or less, 100° or less, or 90° or less. When the liquid-repellent compound has a water contact angle equal to or greater than the above lower limit, it can impart good liquid repellency (particularly water repellency) to the substrate. The water contact angle is the static contact angle of the liquid-repellent compound with respect to a spin-coated film, and is obtained by dropping 2 μL of water onto the spin-coated film at room temperature (25° C.) and measuring the contact angle one second after the drop has landed.

[0032] The liquid-repellent compound is preferably a biobased compound containing carbon of biobased origin. The biobased content is measured in accordance with ASTM D6866.

A high biobased content means that the amount of fossil resource-based materials, such as petroleum, used is small. From this perspective, the higher the biobased content of the liquid-repellent compound, the better.

[0033] The biodegradability of the liquid-repellent compound after 180 days is preferably 5% or more. Since this reduces the environmental impact, a higher biodegradability is preferable. The biodegradability of the liquid-repellent compound after 180 days may be, for example, 10% or more, 20% or more, 30% or more, 50% or more, 60% or more, 70% or more, 80% or more, or 90% or more, preferably 30% or more, more preferably 50% or more, even more preferably 70% or more, and most preferably 80% or more. The biodegradability of the liquid-repellent compound after 60 days is preferably 5% or more. Since this reduces the environmental impact, a higher biodegradability is preferable. The biodegradability of the liquid-repellent compound after 60 days may be, for example, 10% or more, 15% or more, 20% or more, 25% or more, 30% or more, 35% or more, 40% or more, or 45% or more, preferably 10% or more, and more preferably 30% or more. Such biodegradability may be biodegradability as defined in JIS K 6953-1 or ASTM D6400.

[0034] The liquid repellent compound may be a low molecular weight (for example, a weight average molecular weight of less than 1500, less than 1000, or 500 or less) and / or a high molecular weight. The weight average molecular weight of the liquid repellent compound may be 100 or more, 200 or more, 300 or more, 400 or more, 500 or more, 1000 or more, 3000 or more, 5000 or more, 10,000 or more, 30,000 or more, 100,000 or more, 300,000 or more, or 500,000 or more, or may be 1,000,000 or less, 750,000 or less, 500,000 or less, 300,000 or less, 100,000 or less, 75,000 or less, 50,000 or less, 30,000 or less, 10,000 or less, 9,000 or less, 8,000 or less, 7,000 or less, 6,000 or less, 5,000 or less, 3,000 or less, 2,000 or less, 1,000 or less, or 500 or less.

The content of the preservative is preferably 0.0001 to 1 wt % relative to the total weight of the repellent. When the content of the preservative is equal to or greater than the lower limit of the above range, the effect of adding the preservative is sufficiently obtained, and when it is equal to or less than the upper limit, the storage stability of the repellent is good.

[0256] (anti-slip agent) These components have the effect of preventing slippage of fibers and sewn parts during sewing and wearing. Examples of anti-slip agents include polysiloxane compounds, colloidal silicas, silicone resin derivatives, colloidal organic silicones, and amino-modified silicones.

[0260] <Manufacturing method of treated products> The method of making a treated product of the present disclosure includes treating a substrate with a repellent agent.

[0261] [Processed products] Substrates that can be treated with the repellent of the present disclosure include textiles, stone, filters (e.g., electrostatic filters), dust masks, fuel cell components (e.g., gas diffusion electrodes and gas diffusion supports), glass, paper, wood, leather, fur, asbestos, brick, cement, metals and oxides, ceramic products, plastics, painted surfaces, and plaster. Various examples of textiles can be cited. Examples include natural fibers of animal and plant origin, such as cotton, linen, wool, and silk; synthetic fibers, such as polyamide, polyester, polyvinyl alcohol, polyacrylonitrile, polyvinyl chloride, and polypropylene; semi-synthetic fibers, such as rayon and acetate; inorganic fibers, such as glass fiber, carbon fiber, and asbestos fiber; and mixtures of these fibers. As an example of a substrate that can be treated with the repellent, a woven or knitted fabric will be described in detail.

[0262] (woven and knitted fabrics) ·Method of manufacturing knitted fabrics Woven and knitted fabrics can be obtained by weaving and knitting long and short fiber yarns made of the above-mentioned fibers to obtain a greige fabric, which is then post-processed and subjected to a water-repellent treatment. The weaving and knitting can be carried out using known looms and knitting machines, and known equipment can also be used for the preparation process prior to the weaving and knitting.

[0263] The woven or knitted fabric can be post-processed using known scouring and dyeing methods and equipment suitable for the fiber material of the woven or knitted fabric.

[0264] 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 agent (which may be the repellent agent of the present disclosure) is prepared. Next, the aqueous solution is applied to the woven or knitted fabric after the post-processing using a padding method, a spray method, a kiss roll coater method, a slit coater method, or the like, and then dried and subjected to a dry heat treatment. The aqueous solution may also contain a crosslinking agent, a softener, an antistatic agent, or the like, as necessary. After the water-repellent treatment, the woven or knitted fabric may be calendered.

[0265] The woven and knitted fabrics are suitable for use in clothing applications where water repellency is required, particularly in sportswear applications for outdoor activities, skiing, snowboarding, golf, etc., and uniform applications.

[0266] Laminated fabric The woven / knitted fabric of the present disclosure may be provided as a laminated fabric having a moisture-permeable waterproof layer on one side thereof. The moisture-permeable waterproof layer may be laminated directly onto the woven / knitted fabric, or may be laminated onto the woven / knitted fabric via an adhesive layer. When the laminated fabric of the present disclosure is used for clothing or the like, the woven / knitted fabric side is arranged to repel rainwater and the like.

[0267] Breathable waterproof layer The moisture-permeable waterproof layer is a layer that covers one side of a woven or knitted fabric, and is a layer formed of a waterproof and moisture-permeable resin or structural film.

[0268] The moisture-permeable waterproof layer may be formed by applying a resin (the resin that constitutes the moisture-permeable waterproof layer) directly to the woven or knitted fabric, or may be laminated to one side of the woven or knitted fabric via an adhesive layer described below.

[0269] The resin that constitutes the moisture-permeable waterproof layer is not particularly limited, but non-porous and porous resins are used. For non-porous ones, polyurethane resins and polyester elastomer resins that contain hydrophilic components are used to provide moisture permeability. For porous ones, polyurethane resins that form wet-process porous membranes and polyurethane resins that are made porous by electrospinning are used, as well as porous PTFE membranes and porous membranes made of PE or PP.

[0270] As the polyurethane resin, a conventionally known resin obtained by reacting a polyisocyanate component with a polyol component can be used.

[0271] The moisture-permeable waterproof membrane with a microporous structure can be obtained by wet coagulation of a DMF solution of polyurethane resin containing inorganic fine powder. 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 content of the inorganic fine powder is preferably 3 to 50 wt %, and more preferably 5 to 50 wt %, of the total amount of the moisture-permeable waterproof layer.

[0272] The thickness of the moisture-permeable waterproof layer is preferably 5 μm or more, and more preferably 10 to 30 μm. A thickness within the above range provides an excellent balance between waterproofness and moisture permeability, and is also advantageous in terms of texture.

[0273] ·Adhesive layer The laminated fabric preferably includes an adhesive layer. That is, the woven or knitted fabric and the moisture-permeable waterproof layer are preferably laminated via an adhesive layer. In addition, it is preferable that the adhesive layer is a discontinuous layer such as a dot or grid pattern in terms of moisture permeability.

[0274] The type of adhesive that constitutes the adhesive layer is not particularly limited, but it is preferable that it has excellent adhesion to the moisture-permeable waterproof layer. For example, if a resin containing polyurethane resin as the main component is selected as the resin that constitutes the moisture-permeable waterproof layer, it is preferable to use an adhesive layer made of a polyurethane-based adhesive. The polyurethane-based adhesive may be of any structure, such as an ether-based, ester-based, or polycarbonate-based adhesive.

[0275] The adhesive layer may be formed over the entire surface of one side of the woven or knitted fabric, or may be formed in a pattern from the viewpoint of moisture permeability, texture, etc. The pattern shape is not particularly limited, but examples include dots, lines, a grid, a checkerboard pattern, a tortoiseshell pattern, etc., and it is preferable that any of these patterns be uniformly arranged over the entire surface.

[0276] The thickness of the adhesive layer is preferably about 10 to 100 μm, and more preferably 20 to 80 μm.

[0277] Lining fabric In the laminated fabric of the present disclosure, a lining fiber fabric may be laminated on the moisture-permeable waterproof layer (on the side of the moisture-permeable waterproof layer opposite to the side on which the woven or knitted fabric of the present disclosure is laminated). The lining fiber fabric can protect the moisture-permeable waterproof layer and can provide even better waterproofness (water pressure resistance) and strength.

[0278] Examples of the fiber fabric for the lining include various woven fabrics, knitted fabrics, etc. Among them, knitted fabrics are preferred because, compared with woven fabrics, the constituent yarns are more likely to protrude from the surface, resulting in an uneven surface, and the knitted fabric exhibits a stronger anchoring effect, making it less likely to peel off from the moisture-permeable waterproof layer.

[0279] Furthermore, tricot knitted fabrics are also preferred in that they can be produced as long grey fabrics during knitting, have few seams, and can be evenly layered on the moisture-permeable waterproof layer.

[0280] The material of the fibers constituting the lining fiber fabric is not particularly limited and can be selected as appropriate, but nylon fiber is preferred. This is because acid dyes are generally used in nylon fibers, which makes it less likely for the disperse dye to migrate and sublimate into the moisture-permeable waterproof layer, a problem that occurs with polyester fibers, etc., which use disperse dyes. The form (long fiber, short fiber, or spun yarn) or fineness of the fibers constituting the lining fiber fabric are not particularly limited and can be selected as appropriate as long as the effects of the present disclosure are not impaired.

[0281] · Properties of laminated fabric The laminated fabric has excellent waterproofness. A suitable example of the waterproofness of the laminated fabric of the present disclosure is a water level measured according to the water resistance test specified in JIS L 1092:2009 Method A (low water pressure method) of 10,000 mm or more, preferably 15,000 mm or more, more preferably 16,000 mm or more, and particularly preferably 20,000 mm or more.

[0282] The laminated fabric has excellent moisture permeability. A suitable example of the moisture permeability of the laminated fabric of the present disclosure is a fabric having a moisture permeability of, for example, 10,000 g / m 2 as measured according to JIS L 1099:2021 B-1 method (potassium acetate method). 224 hours or more, preferably 15,000 g / m 2 24 hours or more, more preferably 20,000 g / m 2 The upper limit of the moisture permeability is not particularly limited, but is, for example, 40,000 g / m 2 24h or 35,000g / m 2 24h mm. In addition, the moisture permeability measured in accordance with JIS L 1099:2021 A-1 method (calcium chloride method) is, for example, 4000 g / m 2 24 hours or more, preferably 8000g / m 2 24 hours or more, more preferably 10,000 g / m 2 The upper limit of the moisture permeability is 13,000 to 15,000 g / m², which is the limit of the measurement method. 2 Approximately 24 hours.

[0283] In the laminated fabric of the present disclosure, the peel strength between the woven or knitted fabric and the breathable waterproof layer, measured according to the method of JIS K 6404-2, is preferably 2.55 N / 2.54 cm or more for clothing applications, and may be preferably 5 N / 2.54 cm or more for use in applications.

[0284] ·Laminated fabric manufacturing method The method for producing the laminated fabric is not particularly limited, but examples thereof include the first and second production methods described below. First manufacturing method: The first manufacturing method includes a step of forming the moisture-permeable waterproof layer by applying a resin that constitutes the moisture-permeable waterproof layer to the surface of a woven or knitted fabric. Second manufacturing method: This method includes the steps of forming an adhesive layer on the woven or knitted fabric or the moisture-permeable waterproof layer, and bonding the woven or knitted fabric and the moisture-permeable waterproof layer together via the adhesive layer.

[0285] In the first manufacturing method, the resin that constitutes the moisture-permeable waterproof layer can be applied to the surface of the woven or knitted fabric by, for example, a coating method. A knife coater or a comma coater can be used in the coating method. From the viewpoint of providing excellent moisture permeability, it is preferable to obtain the moisture-permeable waterproof layer by a wet method.

[0286] In the second manufacturing method, an example of a method for forming an adhesive layer on a woven or knitted fabric or a moisture-permeable waterproof layer is a lamination method. In the lamination method, a method using a resin solution or a hot melt method can be used to form the adhesive layer. First, a moisture-permeable waterproof layer-forming resin composition (e.g., a resin composition containing a resin and an organic solvent) is applied to the surface of a release material (such as release paper, release cloth, or release film) with a clearance, and a moisture-permeable waterproof layer is formed while adjusting the thickness, followed by drying and heat treatment to obtain a film. The release material can be removed as appropriate after lamination or after aging. Furthermore, when laminating using a hot melt method, the release material can be peeled off and the film alone can be laminated. In addition, the breathable waterproof membrane can be bonded to membranes produced using solvent-free extrusion methods such as the T-die method and inflation, porous membranes produced using the electrospinning method, and porous membranes made of PTFE, PE, PP, etc.

[0287] An adhesive layer is then formed on the woven or knitted fabric or the moisture-permeable waterproof layer. For example, if a resin solution is used, a two-component curing polyurethane resin solution with a viscosity in the range of 500 to 5,000 mPa·s may be applied to the entire surface or in a pattern. The resulting solution is then dried to form an adhesive layer. The woven or knitted fabric and the moisture-permeable waterproof layer are then bonded together via the adhesive layer, and the two are then pressure-bonded or thermocompression-bonded to complete the second manufacturing method.

[0288] On the other hand, in the case of hot melt, it is preferable to use a moisture-curing resin that reacts with moisture in the air, and in practical use, it is more preferable to use one that melts in a temperature range of about 80 to 150°C. In this case, the hot melt resin is first melted while taking into consideration the melting point of the resin and its viscosity when melted. The molten resin is then applied to the woven or knitted fabric or the moisture-permeable waterproof layer to form an adhesive layer, and the woven or knitted fabric and the moisture-permeable waterproof layer are bonded together and pressed together, thereby completing the second manufacturing method. Alternatively, if texture is important, the resin can be applied in a pattern to the moisture-permeable waterproof membrane and then bonded to the woven or knitted fabric.

[0289] Thereafter, a lining fiber fabric can be laminated on the moisture-permeable waterproof layer using any known appropriate method.

[0290] ·Applications of laminated fabric The laminated fabric has excellent water repellency and breathable waterproof properties, and the breathable waterproof layer does not peel off even in harsh environments, making it suitable for use in fields such as uniforms, sportswear, and outdoor products used outdoors.

[0291] [Processing method] The repellent agent of the present disclosure can be applied to a substrate as a treatment agent (particularly a surface treatment agent) by conventionally known methods. The repellent agent of the present disclosure may be dispersed and diluted in an organic solvent or water, if necessary, and then applied to the surface of the substrate by known methods such as dip coating, spray coating, or foam coating, followed by drying. After drying, a textile product is obtained with the solid components of the repellent adhered thereto. If necessary, the repellent agent may be applied together with an appropriate crosslinking agent and cured. Furthermore, the repellent agent of the present disclosure may be used in combination with various additives such as water and / or oil repellents, antislip agents, antistatic agents, texture modifiers, softeners, antibacterial agents, flame retardants, paint fixatives, wrinkle inhibitors, drying speed modifiers, crosslinking agents, film-forming aids, compatibilizers, antifreeze agents, viscosity modifiers, UV absorbers, antioxidants, pH adjusters, insect repellents, and antifoaming agents. Examples of various additives may be the same as those described above under "Other Components" for the repellent agent. The concentration of the hydrocarbon-based water-repellent resin in the treatment agent to be brought into contact with the substrate may be changed appropriately depending on the application, but may be 0.01 to 10% by weight, for example 0.05 to 5% by weight.

[0292] [Textile products] There are various examples of textile products that can be used as the substrate, such as cloth products and paper products.

[0294] Examples of paper products include paper made from bleached or unbleached chemical pulp such as kraft pulp or sulfite pulp, bleached or unbleached high-yield pulp such as groundwood pulp, mechanical pulp or thermomechanical pulp, recycled paper pulp such as recycled newspaper, recycled magazine paper, recycled corrugated cardboard or deinked recycled paper, paper containers, paper molded articles, etc. Specific examples of paper products include food packaging paper, gypsum board base paper, coated base paper, medium-quality paper, general liners and corrugating mediums, neutral white roll paper, neutral liners, rust-proof liners and metal interleaving paper, kraft paper, neutral printing and writing paper, neutral coated base paper, neutral PPC paper, neutral thermal paper, neutral pressure-sensitive base paper, neutral inkjet paper and neutral information paper, molded paper (molded containers), etc.

[0295] The repellent can be applied to the textile by any of the known methods for treating textiles (e.g., fabric) with a liquid. The textile may be immersed in the repellent, or the solution may be applied or sprayed onto the textile. The treated textile is preferably dried and cured by heating to develop water and oil repellency. The heating temperature may be, for example, 100°C to 200°C, 100°C to 170°C, or 100°C to 120°C. In the present disclosure, good performance can be obtained even with low-temperature heating (e.g., 100°C to 140°C). In the present disclosure, the heating time may be 5 seconds to 60 minutes, for example, 30 seconds to 3 minutes.

[0296] Alternatively, the polymer may be applied to the textile by a cleaning process, such as in a laundry application or a dry cleaning process.

The repellents of the present disclosure are particularly effective in making textiles (e.g., synthetic fibers) water repellent.

[0298] 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 types.

Examples of semi-synthetic fibers include acetate and triacetate. Examples of regenerated fibers include rayon, cupro, polynosic rayon, lyocell, and Tencel. Examples of inorganic fibers include glass fiber and carbon fiber.

[0301] Alternatively, the textile may be leather, and the manufacturing polymer may be applied to the leather from an aqueous solution or emulsion at various stages of leather processing, for example, during wet processing of the leather or during finishing of the leather, to render the leather hydrophobic and oleophobic. Alternatively, the textile product may be paper. The manufacturing polymer may be applied to preformed paper or may be applied at various stages of papermaking, for example, during the drying period of the paper.

[0302] "Treatment" means applying the repellent to a substrate by dipping, spraying, painting, etc. By the treatment, the polymer, which is the active ingredient of the repellent, penetrates into the interior of the substrate and / or adheres to the surface of the substrate.

[0303] [Pretreatment of textile products] The textile may be pretreated before being treated with the repellent of the present disclosure. Pretreatment of the textile may impart excellent durability to the textile after treatment with the repellent.

The pretreatment liquid may be dispersed and diluted in an organic solvent or water as necessary, and applied to the surface of the textile product by known methods such as dip coating, spray coating, foam coating, etc., followed by drying. The pH and temperature of the pretreatment liquid may be adjusted depending on the desired degree of treatment. As an example of a method for pretreating textile products, a method for pretreating textile products with a hydrocarbon-based water repellent will be described in detail below.

The attachment of the compound may be in a state where a part of the compound is chemically bonded to a part of the fiber, to the extent that a sufficient amount of the specific functional group remains. (ii) A fiber is prepared in which the specific functional group is directly introduced into the material that constitutes the fiber.

[0309] In the case of (i), for example, functional group-containing fibers can be obtained by a functional group introduction step in which a fiber material is treated with a pretreatment liquid containing one or more compounds having the above-mentioned specific functional groups.

[0330] Methods for treating textile materials with the pretreatment solution include, for example, padding, immersion, spraying, and coating. Examples of padding include methods using padding devices, such as those described on pages 396-397 of "Textile Dyeing and Processing Dictionary" (published by Nikkan Kogyo Shimbun, 1963) and pages 256-260 of "Color Dyeing Chemistry III" (published by Jikkyo Publishing Co., Ltd., 1975). Examples of coating include methods using coating machines, such as those described on pages 473-477 of "Dyeing and Finishing Equipment Directory" (published by Sen-sha, 1981). Examples of immersion include methods using batch dyeing machines, such as those described on pages 196-247 of "Dyeing and Finishing Equipment Directory" (published by Sen-sha, 1981). These machines include jet dyeing machines, air jet dyeing machines, drum dyeing machines, winch dyeing machines, washer dyeing machines, and cheese dyeing machines. Examples of spray treatments include air spraying, which sprays the treatment liquid in a mist form using compressed air, and methods using hydraulic atomization air spraying. The treatment conditions, such as the concentration of the treatment liquid and the heat treatment after application, can be appropriately adjusted taking into account various conditions, such as the purpose and performance. Furthermore, if the pretreatment liquid contains water, it is preferable to dry the pretreatment liquid after application to the fiber material to remove the water. The drying method is not particularly limited, and can be either a dry heat method or a wet heat method. The drying temperature is also not particularly limited, and can be, for example, drying at room temperature to 200°C for 10 seconds to several days. If necessary, heat treatment at a temperature of 100 to 180°C for 10 seconds to 5 minutes may be performed after drying.

[0331] When the textile material is to be dyed, the treatment with the pretreatment liquid may be carried out before dyeing or in the same bath as the dyeing. However, when reduction soaping is carried out, there is a risk that the compound having the above-mentioned specific functional group (e.g., a phenolic polymer compound) adsorbed during the process may fall off, so it is preferable to carry out the treatment after reduction soaping after dyeing.

[0332] The treatment temperature in the immersion treatment can be set to 60 to 130° C. The treatment time can be set to 5 to 60 minutes.

[0333] In the functional group introduction step using a pretreatment liquid, the amount of the compound having the specific functional group attached is preferably 1.0 to 7.0 parts by weight per 100 parts by weight of the textile material. Within this range, durable water repellency and texture can both be achieved at high levels.

[0334] The pH of the pretreatment liquid is preferably adjusted to 3 to 5. The pH can be adjusted using a pH adjuster such as acetic acid or malic acid.

[0335] The pretreatment solution may contain a salt in order to effectively adsorb the compound having the specific functional group onto the fiber material by the salting-out effect. Examples of salts that can be used include sodium chloride. Examples of suitable ammonium carbonate include sodium carbonate, sodium carbonate, ammonium sulfate, and sodium sulfate.

[0336] In the functional group introduction step using a pretreatment liquid, it is preferable to remove the compound having the specific functional group that has been treated in excess. An example of a removal method is washing with water. By performing sufficient removal, it is possible to prevent the development of water repellency in the subsequent water repellent treatment from being hindered, and in addition, the feel of the resulting textile product is improved. Furthermore, it is preferable to thoroughly dry the resulting functional group-containing fiber before contacting it with a hydrocarbon-based water repellent.

[0337] (ii) An example of a fiber in which the specific functional group is directly introduced into the material that constitutes the fiber is cationic dyeable polyester (CD-PET).

[0338] From the viewpoint of improving the water repellency of the resulting textile product, the functional group-containing fiber preferably has a surface zeta potential of −100 to −0.1 mV, more preferably −50 to −1 mV. The zeta potential of the fiber surface can be measured, for example, using a zeta potential / particle size measurement system ELSZ-1000ZS (manufactured by Otsuka Electronics Co., Ltd.). [Example]
