[0017] The hydrophobic monomer (a1) may have at least one hydrocarbon group having 2 to 40 carbon atoms. The hydrocarbon group is preferably an aliphatic hydrocarbon group, particularly a saturated aliphatic hydrocarbon group, and especially an alkyl group. The hydrocarbon group may be linear or branched, and is preferably linear.

[0019] R 11 The hydrocarbon group is preferably a branched or linear (preferably a long-chain linear) hydrocarbon group. The hydrocarbon group is preferably an aliphatic hydrocarbon group, especially a saturated aliphatic hydrocarbon group, and especially an alkyl group.

X' is -(CH2) m -(m is an integer from 1 to 5), a linear hydrocarbon group having an unsaturated bond with 1 to 5 carbon atoms, a branched hydrocarbon group having 1 to 5 carbon atoms, or -(CH2) l -C6H4-(CH2) l -(l is an independent integer between 0 and 5, and -C6H4- is a phenylene group).

[0122] 〔silicone〕 The water-repellent composition in this disclosure preferably contains silicone in addition to the hydrophobic monomer (a1). By including silicone, it is possible to achieve a good combination of water repellency and slip resistance.
[0123] Silicone is, formula: (R 53 )3Si-O-[-Si(R 51 )2-O-] a -[-Si(R 51 )2-O-] b -Si(R 53 )3(S1) [In the formula, R 51 Each of these independently represents a hydrogen atom, an alkyl group having 1 to 40 carbon atoms, an aryl group having 6 to 40 carbon atoms, or an alkoxy group having 1 to 40 carbon atoms.

It may be a polymer shown in [the formula].
[0124] R 51 and R 53 In this, the alkyl group having 1 to 40 carbon atoms and the aryl group having 6 to 40 carbon atoms may be unsubstituted or substituted. R 51 and R 53 Specific examples include methyl group, ethyl group, propyl group, butyl group, pentyl group, hexyl group, heptyl group, octyl group, nonyl group, decyl group, dodecyl group, tetradecyl group, hexadecyl group, octadecyl group; cyclopentyl group, cyclohexyl group, cycloheptyl group; phenyl group, tolyl group, naphthyl group, or groups in which some or all of the hydrogen atoms bonded to these groups are substituted with halogen atoms, amino groups, cyano groups, etc. 51 and R 53 It is preferable that the group is a methyl group or an ethyl group. R 51 and R 53 In this context, the alkoxy group having 1 to 40 carbon atoms may be linear or branched. Examples of alkoxy groups having 1 to 40 carbon atoms include the methoxy group, ethoxy group, propoxy group, and butoxy group.
[0125] Silicones may have at least one long-chain hydrocarbon group. For example, R in formula (S1) 51 At least one of R 53 At least one of the following, or R 51 and R 53 At least one of each of them may be a long-chain hydrocarbon group, 51At least one of the groups (for example, one) may be a long-chain hydrocarbon group. Here, the long-chain hydrocarbon group may be a saturated hydrocarbon group with 6 or more, 10 or more, 15 or more, or 20 or more atoms, preferably 10 or more or 23 or more atoms. Here, the hydrocarbon group may be linear or branched, and is preferably an alkyl group. Specific examples of hydrocarbon groups are hexyl group (6 carbon atoms), octyl group (8 carbon atoms), lauryl group (12 carbon atoms), myristyl group (14 carbon atoms), stearyl group (18 carbon atoms), behenyl group (22 carbon atoms), tricosyl group (23 carbon atoms), lignoceryl group (tetracosyl group, 24 carbon atoms), cellotyl group (hexacosyl group, 26 carbon atoms), montyl group (octacosyl group, 28 carbon atoms), merisyl group (triacontane group, 30 carbon atoms), and dotriacontane group (32 carbon atoms).
[0126] In terms of being easy to manufacture industrially and readily available, the long-chain hydrocarbon group R 51 and R 53 Other than R 51 and R 53 It is preferably a hydrogen atom or a methyl group, and more preferably a methyl group.
[0127] a is a non-negative integer. In terms of ease of industrial manufacture and availability, a may be 40 or less, 30 or less, or 20 or less, and preferably 30 or less.
[0128] The sum of a and b is between 5 and 200. Preferably, the sum of a and b is between 10 and 100, and more preferably between 40 and 60, in terms of ease of industrial manufacture, availability, and handling. a may be between 0 and 150, for example, 1 and 100. The lower limit of b may be 1, 2, or 3, and the upper limit of b may be 150, 10, or 5.
[0129] If a or b is 2 or more, there are multiple R 51 and R 52 Each of these may be the same or different.
[0130] R51 and R 53 Base (for example, when expressed by the following formula (S2) R 51 and R 52 Base and R 53 It is preferable that 50 mol% or more of the total number of groups are methyl groups.
[0131] The order of existence of the repeating units enclosed by a or b is not limited to the order shown in the chemical formula, but is arbitrary. That is, the silicone may be a random polymer or a block polymer.
[0132] For example, silicone is given by formula: (R 53 )3Si-O-[-Si(R 51 )2-O-] a -[-Si(R 51 )(R 52 )-O-] b -Si(R 53 )3(S2) [In the formula, R 51 Each of these independently represents a hydrogen atom, an alkyl group having 1 to 40 carbon atoms, an aryl group having 6 to 40 carbon atoms, an alkoxy group having 1 to 40 carbon atoms, or a long-chain hydrocarbon group. R 52 Each of these independently represents a long-chain hydrocarbon group. R 53 Each of these independently represents a hydrogen atom, an alkyl group having 1 to 40 carbon atoms, an aryl group having 6 to 40 carbon atoms, an alkoxy group having 1 to 40 carbon atoms, or a long-chain hydrocarbon group. a represents an integer greater than or equal to 0, b represents an integer greater than or equal to 1, and (a+b) is between 5 and 200. It may be a polymer shown in [the formula]. In equation (S2), R 51 and R 53 It may have an alkyl group having 3 to 40 carbon atoms or an unsaturated hydrocarbon group having 6 to 40 carbon atoms (for example, a hydrocarbon group having an aromatic ring), but it is preferable that it does not have these groups.
[0133] Examples of silicones are as follows: [ka] [In the formula, a represents an integer between 0 and 150, b represents an integer between 1 and 150. (a+b) is between 5 and 200. n is an integer between 1 and 36 (preferably n is a long-chain hydrocarbon group).
[0134] Silicones can be synthesized by conventionally known methods. For example, a silicone can be obtained by hydrosilylation of an α-olefin with a silicone having an SiH group.
[0135] Examples of silicones having SiH groups include methyl hydrogen silicone with a degree of polymerization of 10 to 200, or copolymers of dimethylsiloxane and methyl hydrogen siloxane. Among these, methyl hydrogen silicone is preferred because it is easy to manufacture industrially and readily available. Hydrogen silicone (e.g., methyl hydrogen silicone) is a polydiorganosiloxane in which part of the side chain is replaced with hydrogen, and the hydrogen atoms are directly bonded to silicon atoms. When using hydrogen silicone, a catalyst may be used to improve reactivity. For example, zinc, tin, manganese, cobalt, iron, and amine-based catalysts can be used. Organic acid metal salts are preferred as catalysts, and fatty acids are preferred as organic acids. Zinc stearate can be used from the viewpoint of ease of handling. It is preferable to use the catalyst at a concentration of 10 to 40% relative to the methyl hydrogen silicone, as this makes it easier to exhibit its effect. Two or more types of amino-modified, epoxy-modified, carboxy-modified, and methyl hydrogen silicones may be mixed. All of them are silicones having reactive groups and preferably have film-forming properties. Film-forming properties refer to the ability of a silicone to form a solid film, rather than an oily or gel-like film, after being applied to the fiber surface in an emulsion state.
[0136] Alpha-olefins are compounds from which long-chain hydrocarbon groups are derived in silicones. Specific examples of alpha-olefins include 1-tricosene, 1-tetracosene, 1-hexacosene, 1-octacosene, 1-triaconthene, and 1-dotriaconthene. The hydrosilylation reaction may be carried out by reacting the α-olefin with the SiH group-containing silicone in a stepwise or one-time manner, if necessary, in the presence of a catalyst.
[0137] The amounts of SiH-containing silicone and α-olefin used in the hydrosilylation reaction can be appropriately selected depending on the SiH group equivalent or number-average molecular weight of the SiH-containing silicone.
[0138] Examples of catalysts used in hydrosilylation reactions include compounds such as platinum and palladium, with platinum compounds being preferred. Examples of platinum compounds include platinum(IV) chloride.
[0139] The reaction conditions for the hydrosilylation reaction are not particularly limited and can be adjusted as appropriate. The reaction temperature is, for example, 10 to 200°C, preferably 50 to 150°C. The reaction time can be, for example, 3 to 12 hours when the reaction temperature is 50 to 150°C. Hydrosilylation reactions are preferably carried out under an inert gas atmosphere. Examples of inert gases include nitrogen and argon. The reaction will proceed even without a solvent, but a solvent may be used. Examples of solvents include dioxane, methyl isobutyl ketone, toluene, xylene, and butyl acetate.
[0140] (Reactive silicone) The silicone may include a reactive silicone. Examples of reactive silicones include polysiloxanes having reactive groups in the side chain, one end, both ends, or both ends. However, from the viewpoint of having excellent slip resistance and water repellency, a polysiloxane having reactive groups in the side chain and / or both ends may also be used. The reactive silicone is not particularly limited as long as it has reactive groups in the molecule, but examples include amino-modified silicones, epoxy-modified silicones, carboxy-modified silicones, and hydrogen-modified silicones. The reactive silicone may be one in which one or more substituents in the above formula (S1) or formula (S2) are substituted with reactive groups.
[0141] Examples of amino-modified silicones include those having a structure in which an amino group is bonded to an organic group directly attached to a silicon atom. The organic group may be either an alkylene group or a divalent aromatic group. Alkylene groups with 2 or more carbon atoms are preferred. Divalent aromatic groups with 6 or more carbon atoms are preferred. The amino group may be a primary, secondary, or tertiary amino group. Examples of organic groups to which an amino group is bonded include: 2-aminoethyl group, N-methyl-2-aminoethyl group, N,N-dimethyl-2-aminoethyl group, N-ethyl-2-aminoethyl group, N,N-diethyl-2-aminoethyl group, N,N-methylethyl-2-aminoethyl group, 3-aminopropyl group, N-methyl-3-aminopropyl group, N,N-dimethyl-3-aminopropyl group, N-ethyl-3-anopropyl group, N,N-diethyl-3-aminopropyl group, and N,N-methylethyl-3-aminopropyl group. These functional groups may be located on the side chains or at the terminal ends of the polysiloxane.
[0142] Examples of epoxy-modified silicones include those having a structure in which an epoxy group is bonded to an organic group directly attached to a silicon atom. The organic group may be either an alkylene group or a divalent aromatic group. Typically, the bond with the organic group is in the form of a glycidyl ether. Examples of such functional groups include 3-glycidoxypropyl and 2-glycidoxyethyl groups. These functional groups may be located on the side chains or at the terminals of the polysiloxane.
[0143] Examples of carboxylated silicones include those having a structure in which a carboxyl group is bonded to an organic group directly connected to a silicon atom. The organic group may be either an alkylene group or a divalent aromatic group. Alkylene groups with two or more carbon atoms are preferred. Divalent aromatic groups with six or more carbon atoms are preferred. Examples of such functional groups include 3-carboxypropyl and 2-carboxyethyl groups. These functional groups may be located on the side chains or at the terminals of the polysiloxane.
[0144] (Silicone resin) Silicone may contain silicone resin. Silicone resin is R3SiO 1 / 2 Units (M units), RSiO 3 / 2 Units (T units) and SiO 4 / 2 A silicone resin consisting of at least one selected from units (Q units), where R is a linear or branched monovalent alkyl group having 1 to 18 carbon atoms, excluding silicone resins consisting only of M units or only of Q units). Silicone resin (B) is R2SiO 2 / 2 It is preferable to omit the units (D units) from the viewpoint of achieving the effects of this invention.
[0145] The silicone resin is preferably in a sol state. Examples of R include methyl group, ethyl group, propyl group, isopropyl group, butyl group, isobutyl group, hexyl group, octyl group, 2-ethylhexyl group, decyl group, cetyl group, stearyl group, etc. However, considering the stability when the silicone resin (B) is in a sol state, the availability of raw materials, and cost, R is preferably a methyl group, and in particular, it is preferable that 90% or more of all R are methyl groups. Note that different types of groups may be used in combination for R.
[0146] R2SiO in silicone resin 2 / 2 The inclusion of units (D units) may impair the low slipperiness of the water-repellent composition. Furthermore, a silicone resin consisting solely of Q units may hinder the water-repellent performance of the water-repellent composition.
[0147] Examples of silicone resin structures include (i) M units and Q units, (ii) M units, T units and Q units, (iii) M units and T units, (iv) T units and Q units, and (v) silicone resins consisting only of T units. Preferably, (i) silicone resins consisting of M units and Q units and (v) silicone resins consisting only of T units. The molar ratio (M / Q) of M units to Q units in (i) silicone resins consisting of M units and Q units is preferably M / Q = 0.6 to 1.3, and more preferably M / Q = 0.8 to 1.1. Two or more of these silicone resins may be used in combination.
[0148] Furthermore, silicone resin (B) may contain structural units that include hydroxyl groups bonded to silicon atoms. Specifically, (HO)RSiO 2 / 2 Units, (HO)2RSiO 1 / 2 Unit: (HO)SiO 3 / 2 Unit: (HO)2SiO 2 / 2 Unit: (HO)3SiO 1 / 2 The units may be listed, and some of the hydroxyl groups may be alkoxy groups represented by RO groups.
[0149] A sol containing silicone resin can be obtained by a manufacturing method described in Patent No. 3852921, which involves uniformly dispersing and polymerizing organodisiloxane, tetraalkoxysilane and their partially hydrolyzed condensates in water containing a surfactant, or by a manufacturing method which involves hydrolyzing the silane compounds shown below in water.
[0150] This paper details a manufacturing method for hydrolyzing silane compounds in water. Any silane compound can be used as a raw material for this manufacturing method, as long as it contains one, three, or four hydrolyzable groups, and has an alkyl group that satisfies the above conditions, and the hydrolyzable group is either chlor or alkoxy.Specifically, tetrachlorosilane, tetramethoxysilane, tetraethoxysilane, tetrabutoxysilane, methyltrichlorosilane, methyltrimethoxysilane, methyltriethoxysilane, methyltriisopropoxysilane, methyltributoxysilane, ethyltrichlorosilane, ethyltrimethoxysilane, ethyltriethoxysilane, propyltrichlorosilane, propyltrimethoxysilane, propyltriethoxysilane, isopropyltrichlorosilane, isopropyltrimethoxysilane, isopropyltriethoxysilane, butyl Lichlorosilane, butyltrimethoxysilane, butyltriethoxysilane, isobutyltrichlorosilane, isobutyltrimethoxysilane, isobutyltriethoxysilane, hexyltrichlorosilane, hexyltrimethoxysilane, hexyltriethoxysilane, 2-ethylhexyltrichlorosilane, 2-ethylhexyltrimethoxysilane, 2-ethylhexyltriethoxysilane, decyltrichlorosilane, decyltrimethoxysilane, decyltriethoxysilane, cetyltrichlorosilane, cetyltrimethoxysilane, cetyltriethoxy Silane, stearyltrichlorosilane, stearyltrimethoxysilane, stearyltriethoxysilane, trimethylchlorosilane, trimethylmethoxysilane, trimethylethoxysilane, trimethylisopropoxysilane, dimethylethylchlorosilane, dimethylethylmethoxysilane, dimethylethylethoxysilane, dimethylpropylchlorosilane, dimethylpropylmethoxysilane, dimethylpropylethoxysilane, dimethylisopropylchlorosilane, dimethylisopropylmethoxysilane, dimethylisopropylethoxysilane, dimethylisopropylethoxysilane, dimethylisopropyl methoxysilane, dimethylisopropylethoxysilane, dimethyl Methylhexylchlorsilane, dimethylhexylmethoxysilane, dimethylhexylethoxysilane, dimethyldecylchlorsilane, dimethyldecylmethoxysilane, dimethyldecylethoxysilane, dimethylcetylchlorsilane, dimethylcetylmethoxysilane, dimethylcetylethoxysilane, dimethylstearylchlorsilane, dimethylstearylmethoxysilane, dimethylstearylethoxysilane, and their partial hydrolysates are examples of usable silane compounds, but the usable silane compounds are not limited to these.Due to ease of handling, ease of removing by-products, and availability of raw materials, it is more preferable to use methoxysilane or ethoxysilane. One or more of these silane compounds may be used.
[0151] Common methods that are generally known can be used to hydrolyze silane compounds in water. These include methods such as adding the silane compound dropwise to water while carrying out the hydrolysis reaction, or mixing the water and silane compound together and then carrying out the hydrolysis reaction. A hydrolysis catalyst may be used when carrying out the hydrolysis reaction. Conventional known catalysts can be used as hydrolysis catalysts, and it is preferable to use acidic or alkaline catalysts. In the case of acidic catalysts, solid acids such as hydrogen halides, carboxylic acids, sulfonic acids, acidic or weakly acidic inorganic salts, and ion exchange resins are preferred. In the case of alkaline catalysts, alkali metal salts such as sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, and sodium bicarbonate, alkali metal silanolates such as sodium silanolate and potassium silanolate, amines such as triethylamine, diethylamine, and aniline, and aqueous ammonia can be used. It is preferable to adjust the amount of catalyst added so that the pH of the aqueous solution is 2 to 7 and 7 to 12. After the reaction is complete, a neutralizing agent to neutralize the acidic or alkaline catalyst may be added as needed.
[0152] A surfactant may be added to the aqueous solution to disperse the silane compound and the hydrolysis reaction product in water. There are no particular restrictions on the surfactant, but for example, anionic surfactants such as alkyl sulfates, alkylbenzene sulfons, and alkyl phosphates; nonionic surfactants such as polyoxyethylene alkyl ethers, polyoxyethylene oxypropylene alkyl ethers, polyoxyethylene alkylphenyl ethers, and polyoxyethylene fatty acid esters; cationic surfactants such as quaternary ammonium salts and alkylamine acetates; and amphoteric surfactants such as alkyl betaines and alkylimidazolines can be used, either alone or in combination of two or more. Furthermore, surfactants that exhibit acidity or alkalinity can also be used as hydrolysis catalysts. There are no particular restrictions on the amount of surfactant to be added, but it is preferable to add 1 to 50 parts by weight per 100 parts by weight of the silane compound. If the amount is less than 1 part by weight, the effect of adding the surfactant will not be sufficiently obtained, and if it is more than 50 parts by weight, the water repellency of the water repellent may be impaired.
[0153] A mixture of water and a silane compound may be mixed with a hydrolysis catalyst and surfactant as needed, and the hydrolysis reaction may be carried out at 0-90°C for 10 minutes to 24 hours. Afterward, a neutralization reaction may be carried out as needed to obtain silicone resin. Alcohols and neutralization salts produced as by-products of the hydrolysis reaction can be removed by vacuum distillation or filtration. Various additives can be incorporated into this silicone resin. For example, preservatives and thickeners can be added depending on the purpose.

Being within the above range allows for a good combination of water repellency and slip resistance. The average primary particle diameter can be measured with a microscope (scanning electron microscope or transmission electron microscope). Specifically, an arbitrary position on the fabric is observed from above at an arbitrary magnification using a microscope. Next, if the particle shape is spherical, its diameter is considered as the particle diameter (particle size); if it is non-spherical, the average of the longest and shortest diameters is considered as the particle diameter (particle size). The particle size of all particles present within the field of view is measured, and this process is repeated by moving the field of view and measuring the particle size again. By doing so, the particle size is measured at 10 or more points, and the average value is taken as the average primary particle diameter.

By this method, the water-repellent composition of the present disclosure can be obtained.
[0223] Polymerization methods include, for example, suspension polymerization and emulsion polymerization, and emulsion polymerization is preferred from the viewpoint of obtaining an emulsion of non-fluorine copolymer (A).

[0225] The proportion of the surfactant may be, for example, 1 part by weight or more, preferably 3 parts by weight or more, and for example, 10 parts by weight or less, preferably 5 parts by weight or less, based on 100 parts by weight of the total amount of monomers (specifically, a hydrophobic monomer having a hydrocarbon group having 2 to 40 carbon atoms (a1), at least one chloride monomer selected from the group consisting of vinyl chloride and vinylidene chloride (a2), a cyclic hydrocarbon group-containing monomer added as needed (a3), a crosslinkable monomer added as needed (a4), and other monomers added as needed (a5), and so on).

The amount of organic acid may be, for example, 0.01 parts by weight or more, 0.1 parts by weight or more, 1 part by weight or less, or 0.5 parts by weight or less, per 100 parts by weight of the total amount of monomers.
[0228] Next, an emulsifier may be added to this mixture.

[0230] Furthermore, the above-mentioned surfactants can also be used as emulsifiers.
[0231] Furthermore, the emulsifier may also contain a reactive emulsifier. When the emulsifier contains a reactive emulsifier, the non-fluorinated copolymer (A) (polymer of the above monomers) becomes a polymer that contains constituent units derived from the reactive emulsifier.
[0232] If the non-fluorinated copolymer (A) is a polymer containing structural units derived from a reactive emulsifier, the product stability of the aqueous dispersion (water-repellent composition) is improved without reducing its water repellency.
[0233] A reactive emulsifier is an emulsifying dispersant having radical reactivity, that is, an emulsifier having one or more polymerizable unsaturated groups in its molecule, and is an emulsifier copolymerizable with the monomers described above. Examples of reactive emulsifiers include the reactive emulsifier described in Japanese Patent Publication No. 2017-25440, and preferably, a reactive emulsifier represented by the following formula. [ka]
[0234] In the above formula, R 10 This represents an organic residue having an ethylenically unsaturated double bond group with 12 to 20 carbon atoms.
[0235] R 11 This represents an oxyalkylene group having 2 to 10 carbon atoms, preferably an oxyethylene group.
[0236] If the reactive emulsifier is the reactive emulsifier shown in the above formula, the product stability of the aqueous dispersion (water-repellent composition) is improved without reducing water repellency. Examples of the reactive emulsifier represented by the above formula include polyoxyethylene alkylphenols.
[0237] Emulsifiers can be used alone or in combination of two or more types.
[0238] The proportion of the emulsifier may be, for example, 5 parts by weight or more, and for example, 18 parts by weight or less, per 100 parts by weight of the total amount of monomers.
[0239] Furthermore, the proportion of the emulsifier may be, for example, 8 parts by weight or more, or 20 parts by weight or less, based on 100 parts by weight of the total amount of the isocyanate derivative (B) and the non-fluorine copolymer (A).
[0240] Furthermore, the proportion of the emulsifier may be, for example, 0.5% by weight or more, or for example, 5% by weight or less, relative to the water-repellent composition.
[0241] Then, after mixing the above-mentioned components, the mixture is stirred and subjected to ultrasound to emulsify it.
[0242] As a method of stirring, dispersers such as homomixers, ultrasonic homogenizers, pressurized homogenizers, milders, and porous membrane injection dispersers can be used, and preferably, a homomixer is used.
[0243] The stirring conditions are set as appropriate. When using a homomixer, the rotation speed is set to, for example, 500 rpm or more, and for example, 10,000 rpm or less. The stirring time is, for example, 0.5 minutes or more, and for example, 10 minutes or less, preferably 5 minutes or less. The stirring temperature is, for example, 50°C or more, and for example, 90°C or less.
[0244] Next, if a portion of the monomer was added when preparing the above-mentioned mixture, the remainder of the monomer is added to this mixture.
[0245] Next, a polymerization initiator is added to this mixture.
[0246] Examples of polymerization initiators 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, azo compounds are used, and more preferably, azobisisobutyronitrile is used.
[0247] The proportion of polymerization initiator may be, for example, 0.01 parts by weight or more, and for example, 10 parts by weight or less, per 100 parts by weight of monomer.
[0248] Furthermore, a chain transfer agent may be added to this mixture as needed.
[0249] Examples of chain transfer agents include mercaptan group-containing compounds such as lauryl mercaptan, thioglycol, and thioglycerol (especially alkyl mercaptans (e.g., having 1 to 30 carbon atoms)), inorganic salts such as sodium hypophosphite and sodium bisulfite, and lauryl mercaptan is preferred.
[0250] The proportion 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, per 100 parts by weight of monomer.
[0251] Then, this mixture is heated to polymerize the monomers.
[0252] The heating conditions include a heating temperature of, for example, 40°C or higher, and for example, 80°C or lower, and a heating time of, for example, 1 hour or more, and for example, 6 hours or less. This yields an emulsion of the non-fluorine copolymer (A), and a water-repellent composition containing the isocyanate derivative (B) and the non-fluorine copolymer (A) (emulsion).
[0253] In the first method, the monomers constituting the non-fluorine copolymer (A) described above are polymerized in the presence of the isocyanate derivative (B). However, the isocyanate derivative (B) can also be added after the monomers have been polymerized (second method). Alternatively, the isocyanate derivative (B) can also be added 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-described production method, except that the monomers constituting the 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 this disclosure.
[0255] Alternatively, the monomer can be polymerized to prepare a non-fluorinated copolymer (A), and then the obtained non-fluorinated copolymer (A) can be blended with an isocyanate derivative (B) (Method 4). Alternatively, the monomer can be polymerized first to prepare a non-fluorinated copolymer (A), and then the obtained non-fluorinated copolymer (A) can be blended with an isocyanate derivative (B), a surfactant, and a liquid medium (Method 5).
[0256] In the fourth and fifth methods, examples of polymerization methods include solution polymerization, suspension polymerization, and emulsion polymerization.
[0257] When solution polymerization is employed, the monomer is dissolved in an organic solvent in the presence of the polymerization initiator described above, followed by nitrogen purging and heating while stirring.
[0258] The polymerization initiator described above may be used as the polymerization initiator. The blending 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, per 100 parts by weight of monomer.
[0259] Examples of organic solvents include the solvents listed above in the section on liquid media. The organic solvent may be, for example, 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), or alcohols (e.g., alcohols with 1 to 40 carbon atoms, specifically ethanol, butanol, isopropyl alcohol). Preferably, a water-soluble glycol-based solvent (e.g., ethylene glycol, propylene glycol, etc.) may be used as the organic solvent.
[0260] The proportion of the organic solvent may be, for example, 10 parts by weight or more, preferably 50 parts by weight or more, or, for example, 2000 parts by weight or less, preferably 1000 parts by weight or less, per 100 parts by weight of the monomer.
[0261] As for the heating conditions, the heating temperature may be, for example, 30°C or higher, or 120°C or lower, and the heating time may be, for example, 1 hour or more, or 10 hours or less.
[0262] As a result, a non-fluorine copolymer (A) is obtained.
[0263] Then, after generating a non-fluorinated copolymer (A) by solution polymerization, the organic solvent is removed, and the non-fluorinated copolymer (A) is combined with an isocyanate derivative (B) in a surfactant and a liquid medium to prepare an emulsion of the non-fluorinated copolymer (A).
[0264] <Uses of water-repellent compositions> Examples of applications for the water-repellent compositions in this disclosure include external treatment agents (surface treatment agents) or internal treatment agents, water repellents (water repellents, oil repellents or water- and oil-repellent agents, etc., especially water repellents), antifouling agents, dirt removal agents, release agents, mold release agents (external mold release agents or internal mold release agents), and the like.
[0265] <Manufacturing method for processed products> The method for manufacturing the processed product in this disclosure includes the step of applying the water-repellent composition of this disclosure to a substrate (particularly a fibrous substrate).
[0266] [Processed Products] Examples of substrates treated with the water-repellent composition of this 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, brick, cement, metals and oxides, ceramic products, plastics, painted surfaces, and plaster. Various examples of textile products can be given. For example, natural animal and plant 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 acetate; inorganic fibers such as glass fibers, carbon fibers, and asbestos fibers; or blends thereof. An example of a substrate treated with the water-repellent composition will be described in detail regarding woven and knitted fabrics.
[0267] (Woven or knitted fabrics) • Manufacturing methods for knitted fabrics Woven or knitted fabrics can be obtained by weaving or knitting the above-mentioned blended entangled yarn to obtain raw fabric, and then by post-processing and water-repellent treatment. Weaving and knitting can be carried out using known looms and knitting machines, and the preparatory processes preceding weaving and knitting can also be carried out using known equipment.
[0268] Furthermore, in post-processing, the raw fabric is first scouring and relaxed. Scouring and relaxation can be carried out in a continuous or batch manner at a temperature of 80 to 130°C. Usually, it is preferable to carry it out in a batch manner at a temperature of 100°C or lower, and it is particularly preferable to carry it out using a high-pressure liquid-jet dyeing machine equipped with a jet nozzle.
[0269] After scouring and relaxing, the woven or knitted fabrics are pre-set. Pre-setting is typically done using a pin tenter, dry heat treatment at 170-200°C for 30-120 seconds. After pre-setting, the fabrics are dyed according to conventional methods, followed by final setting as needed.
[0270] After post-processing, the woven or knitted fabric may be treated to be water-repellent. For water-repellent treatment, first, an aqueous solution containing a water-repellent agent (which may be a water-repellent agent composition as described herein) is prepared. Next, the aqueous solution is applied to the woven or knitted fabric after the post-processing using a padding method, spray method, slit coater method, etc., and then dry-heat treated at 105 to 190°C for 30 to 150 seconds. The aqueous solution may also contain a crosslinking agent, softener, antistatic agent, etc., as needed. After water-repellent treatment, the woven or knitted fabric may be calendered to further improve its water-repellent performance.
[0271] Woven and knitted fabrics are suitable for clothing applications, particularly for uniforms, women's wear, and sportswear.
[0272] • Laminated fabric The present disclosure may also be provided as a laminated fabric having a breathable waterproof layer on one side of the woven or knitted fabric. The breathable waterproof layer may be directly laminated to the woven or knitted fabric, or it may be laminated to the woven or knitted fabric via an adhesive layer. When the laminated fabric of the present disclosure is used for clothing or the like, it should be positioned so that the woven or knitted fabric side is exposed to rainwater, etc.
[0273] • Breathable waterproof layer A breathable waterproof layer is a layer that covers one side of a woven or knitted fabric, and is formed from a resin that has waterproof and breathable properties.
[0274] The breathable waterproof layer may be formed by directly applying resin (the resin constituting the breathable waterproof layer) to the woven or knitted fabric, or it may be laminated to one side of the woven or knitted fabric via an adhesive layer described later. In this disclosure, a blended entangled yarn having fine protrusions due to loops or slack is used in the woven or knitted fabric. As a result, the protrusions become firmly entangled with the adhesive layer or the breathable waterproof layer, creating an anchoring effect that makes it even more difficult for the woven or knitted fabric and the breathable waterproof layer to separate. 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 anchoring effect may not be sufficiently realized, and in such cases, the woven or knitted fabric and the breathable waterproof layer tend to separate easily.
[0275] The resin constituting the breathable waterproof layer is not particularly limited, but it is preferably composed of polyurethane resin as the main component, for example, it is preferable that polyurethane resin is contained in a proportion of 80% by weight or more. Polyurethane resin is generally suitable for forming a resin layer that has breathability and waterproofing properties. Among these, a microporous type is preferred when considering breathability, but if there is a possibility of being exposed to rain for a long time or repeated use such as washing is expected, a non-porous type of breathable polyurethane may be used instead of a microporous type.
[0276] As the polyurethane resin, conventionally known resins obtained by reacting a polyisocyanate component with a polyol component can be used.
[0277] The breathable waterproof layer may have a microporous structure or a non-porous structure. Furthermore, if it has a microporous structure, inorganic fine powder may be incorporated into the breathable waterproof layer to ensure the desired breathability.
[0278] Examples of inorganic fine powders include fine powders made from silicon dioxide, aluminum dioxide, or titanium dioxide. The average primary particle size of the inorganic fine powder is preferably about 7 to 40 nm. The amount of inorganic fine powder is preferably 3 to 50% by weight, and more preferably 5 to 50% by weight, relative to the total amount of the moisture-permeable waterproof layer.
[0279] The thickness of the breathable waterproof layer is preferably 5 μm or more, and more preferably 10 to 30 μm. A thickness within this range provides an excellent balance of waterproofing and breathability, and also offers advantages in terms of texture and tear strength.
[0280] ·Adhesive layer The laminated fabric preferably includes an adhesive layer. In other words, it is preferable that the woven or knitted fabric and the breathable waterproof layer are laminated via an adhesive layer. The reason for this is explained below. In this disclosure, as the woven or knitted fabric, as described above, a fabric having fine protrusions on its surface due to loops or slack is used. Therefore, the protrusions become firmly intertwined with the adhesive layer, creating an anchoring effect, which makes it even more difficult for the woven or knitted fabric and the breathable waterproof layer to separate.
[0281] Furthermore, when a breathable waterproof layer is directly laminated onto the woven or knitted fabric, for example by a coating method, protrusions on the surface of the woven or knitted fabric may penetrate the breathable waterproof layer, resulting in the formation of pinholes and inferior water resistance and strength. There is also a concern that the coating may not be uniform, leading to uneven thickness in the breathable waterproof layer. To prevent this, if the surface of the woven or knitted fabric is smoothed by calendering, for example, the protrusions or air-retaining layer may be reduced, which may decrease water repellency. Therefore, in this disclosure, it is preferable that the woven or knitted fabric and the breathable waterproof layer are laminated with an adhesive layer in between.
[0282] The type of adhesive that constitutes the adhesive layer is not particularly limited, but it is preferable that it has excellent compatibility with the breathable waterproof layer. For example, if a resin mainly composed of polyurethane resin is selected as the resin that constitutes the breathable waterproof layer, it is preferable to use an adhesive layer made of polyurethane adhesive. The polyurethane adhesive may be of any structure, such as ether-based, ester-based, or polycarbonate-based, but from the viewpoint of providing excellent breathability, ether-based adhesives are preferred.
[0283] The adhesive layer may be formed over the entire surface of one side of the woven or knitted fabric, or it may be formed in a pattern from the viewpoint of breathability or texture. The pattern is not particularly limited, but examples include dots, lines, grids, checkerboard patterns, tortoiseshell patterns, etc., and it is preferable that they are uniformly arranged throughout.
[0284] The adhesive layer thickness is preferably around 10 to 100 μm, and 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 adhesive occupies a large area, and if it exceeds 100 μm, the manufacturing cost increases and further adhesion cannot be expected, so neither is desirable.
[0285] • Lining fabric In the laminated fabric of this disclosure, a lining fiber fabric may be laminated on the breathable waterproof layer (on the side of the breathable waterproof layer opposite to the side on which the woven or knitted fabric of this disclosure is laminated). The lining fiber fabric can protect the breathable waterproof layer, making it possible to further improve the waterproofness (water pressure resistance) and strength. In addition, by laminating the lining fiber fabric, the elongation of the entire laminated fabric can be suppressed, so that the protrusions of the blended composite yarn are not reduced as a result of being pulled by the elongation of the woven or knitted fabric due to the finishing process after lamination or tension during wear, and the above water repellency can be maintained at a higher level. Furthermore, when a lining fiber fabric is laminated, the water repellency can be further improved.
[0286] Examples of lining fabrics include various woven and knitted fabrics. Among these, knitted fabrics are preferable because, compared to woven fabrics, the constituent threads tend to protrude more easily from the surface, resulting in a less flat surface, which allows for a better anchoring effect and makes it less likely to peel off from the breathable waterproof layer. In particular, tricot knitted fabric is preferable because, compared to knitted fabrics with other structures, its elasticity is suppressed, so the gaps between the stitches do not become too large, and water repellency is more effectively expressed. Furthermore, tricot knitted fabric is also preferable because it can be made into a long piece of fabric during the knitting process, resulting in fewer seams, and can be uniformly laminated on the breathable waterproof layer.
[0287] The material of the fibers constituting the lining fabric is not particularly limited and can be selected as appropriate, but nylon fibers are preferred. This is because, since acid dyes are generally used for nylon fibers, the migration and sublimation of disperse dyes to the breathable waterproof layer, which is a problem with polyester fibers and the like that use disperse dyes, is less likely to occur. The form (long fibers, short fibers, or spun yarn) or fineness of the constituent fibers of the lining fabric is not particularly limited and can be selected as appropriate within a range that does not impair the effects of this disclosure.
[0288] • Characteristics of laminated fabric The laminated fabric has excellent waterproofing properties. A preferred example of the waterproofing properties of the laminated fabric of this disclosure is a water level measured according to the water resistance test specified in JIS L 1092:2009 Method A (low water pressure method), which is, for example, 10,000 mm or more, preferably 15,000 mm or more, more preferably 16,000 mm or more, and particularly preferably 20,000 mm or more. There is no particular limit to the upper limit of the water level, but examples include 50,000 mm or 25,000 mm.
[0289] Laminated fabrics have excellent moisture permeability. A preferred example of the moisture permeability of the laminated fabrics of this disclosure is a moisture permeability of, for example, 10,000 g / m² as measured according to the JIS L 1099:2012 B-1 method (potassium acetate method). 2 24 hours or more, preferably 15,000 g / m² 2 24 hours or more, more preferably 20,000 g / m² 2 • 24 hours or more is a possible example. There are no particular restrictions on the upper limit of this moisture permeability, but for example, 40,000 g / m 2 24h or 35,000g / m² 2 • 24h • mm is one example.
[0290] In the laminated fabric, delamination between the woven / knitted fabric and the breathable waterproof layer is suppressed. In the laminated fabric of this disclosure, a suitable example of the peel strength between the woven / knitted fabric and the breathable 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. To achieve the peel strength within the above range, for example, a woven / knitted fabric that has not been calendered can be used, or an adhesive layer can be provided.
[0291] • Manufacturing method of laminated fabric The method for manufacturing the laminated fabric is not particularly limited, but examples include the first and second manufacturing methods shown below. First manufacturing method: Includes the step of forming the moisture-permeable waterproof layer by applying the resin constituting the moisture-permeable waterproof layer to the surface of a woven or knitted fabric. A second manufacturing method includes the steps of forming an adhesive layer on a woven or knitted fabric or a breathable waterproof layer, and bonding the woven or knitted fabric and the breathable waterproof layer via the adhesive layer.
[0292] It is preferable to maintain as many protrusions as possible on the surface of the woven or knitted fabric used in the laminated fabric (i.e., the woven or knitted fabric of the present disclosure described above). For example, if calendering is applied to the woven or knitted fabric to facilitate coating or other processes, the fine protrusions of the blended entangled yarns may be flattened, resulting in a flat surface, and it may not be possible to achieve a specific water droplet rolling angle. Furthermore, if calendering is applied, it may not be possible to sufficiently maintain the above-mentioned air-retaining layer, and the desired water repellency may not be achieved. Therefore, it is preferable to carefully consider the conditions for calendering. For example, when calendering a woven or knitted fabric, it is advisable to use normal conditions (e.g., a temperature of 130°C or higher and a linear pressure of 200 to 20000 N / cm) that do not reduce the protrusions of the blended entangled yarns too much. Note that calendering may also be performed without heating.
[0293] In the first manufacturing method, a coating method can be used to apply the resin constituting the moisture-permeable waterproof layer to the surface of the woven or knitted fabric. In the coating method, a knife coater or a comma coater can be used. Furthermore, from the viewpoint of providing excellent moisture permeability, it is preferable to obtain the moisture-permeable waterproof layer by a wet method.
[0294] In the second manufacturing method, a lamination method is used as a method for forming an adhesive layer on a woven or knitted fabric or a breathable waterproof layer. In the lamination method, a resin solution or a hot melt method can be used to form the adhesive layer. First, a resin composition for forming a breathable waterproof layer (for example, a resin composition containing a resin and an organic solvent) is applied to the surface of a release agent (release paper, release cloth, or release film, etc.) with a clearance, and the breathable waterproof layer is formed while adjusting the thickness. The mixture is then heat-treated to allow it to react completely and obtain a film. The release agent can be removed as appropriate after lamination or curing.
[0295] Then, an adhesive layer is formed on the woven or knitted fabric or the breathable waterproof layer. For example, if using a resin solution, a two-component curing polyurethane resin solution, adjusted to a viscosity in the range of 500 to 5000 mPa·s, may be applied to the entire surface or in a pattern. After drying, an adhesive layer is formed, and the woven or knitted fabric and the breathable waterproof layer are bonded together via the adhesive layer, and the second manufacturing method can be carried out by pressing or heat-pressing the two together.
[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 in practical terms, it is more preferable to use one that melts in a temperature range of about 80 to 150°C. In this case, first, the hot melt resin is melted while considering the melting point of the resin and the viscosity when melted. Then, the molten resin is applied onto the woven or knitted fabric or the moisture-permeable waterproof layer and allowed to mature while cooling at room temperature to form an adhesive layer. After that, 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 a breathable waterproof layer is laminated using a coating method, there is a concern that pinholes may occur in the breathable waterproof layer due to fine protrusions on the surface of the woven or knitted fabric, which tends to reduce water pressure resistance. Furthermore, when calendering is applied to the woven or knitted fabric in an attempt to form a uniform breathable waterproof layer, there is a concern that the protrusions or air-retaining layer will be reduced, making it impossible to achieve the desired water repellency, and further scrutiny of the calendering conditions will be necessary, which may make the process itself complicated.
[0298] Subsequently, a lining fabric can be laminated onto the breathable waterproof layer using a known and appropriate method.
[0299] • Uses of laminated fabrics Laminated fabrics offer excellent water repellency and breathable waterproofing, and the breathable waterproof layer does not peel off even in harsh environments, making them suitable for use in fields such as uniforms, sportswear, and outdoor products used outdoors.
[0300] [Processing method] The water-repellent composition of this disclosure can be applied to a substrate by conventionally known methods as a treatment agent (particularly a surface treatment agent). The water-repellent composition of this disclosure may be diluted by dispersing it in an organic solvent or water as needed, and then applied to the surface of the substrate by known methods such as immersion coating, spray coating, foam coating, etc., and dried. After drying, a textile product with the solid components of the water-repellent composition attached is obtained. If necessary, it may also be applied together with a suitable crosslinking agent and cured. Furthermore, the water-repellent composition of this disclosure can be used in combination with various additives such as water-repellent and / or oil-repellent agents, anti-slip agents, antistatic agents, texture modifiers, softeners, antibacterial agents, flame retardants, paint fixatives, wrinkle-preventing agents, drying speed modifiers, crosslinking agents, film-forming aids, compatibilizers, antifreeze agents, viscosity modifiers, ultraviolet absorbers, antioxidants, pH adjusters, insecticides, and defoaming agents. Examples of various additives may be the same as those described in "other components" in the water-repellent composition described above. The concentration of the non-fluorine copolymer (A) in the treatment agent that comes into contact with the substrate may be changed as appropriate depending on the application, but may be 0.01 to 10% by weight, for example, 0.05 to 5% by weight.
[0301] [Textile products] Various examples of textile products can be given as base materials, such as cloth products and paper products. Textile products that serve as base materials are also called textile base materials.
[0302] Examples of textile products include natural animal and plant 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 acetate; inorganic fibers such as glass fibers, carbon fibers, and asbestos fibers; or blends thereof.

However, treatment may also be applied to fibers, yarns, and intermediate fiber products (e.g., slivers or rovings) before they are made into fabric.
[0303] Examples of paper products include paper made from bleached or unbleached chemical pulps such as kraft pulp or sulfite pulp, bleached or unbleached high-yield pulps such as crushed wood pulp, mechanical pulp or thermomechanical pulp, recycled paper pulp such as recycled newspaper, recycled magazine, recycled corrugated cardboard or deinked paper, paper containers, and molded products made from paper.

[0304] The water-repellent composition can be applied to textile products (e.g., cloth) by any known method for treating textile products with a liquid. The textile product may be immersed in the water-repellent composition, or the solution may be applied to or sprayed onto the textile product. The treated textile product is preferably dried and cured by heating to exhibit 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. Good performance can also be obtained with low-temperature heating (e.g., 100°C to 140°C) in this disclosure. The heating time may be 5 seconds to 60 minutes in this disclosure, for example, 30 seconds to 3 minutes.
[0305] Alternatively, the water-repellent composition may be applied to textile products by cleaning methods, for example, by washing or dry cleaning.
[0306] The textile products to be treated may be cloths, including woven fabrics, knitted fabrics and nonwoven fabrics, cloths in the form of clothing and carpets, but may also be fibers or yarns or intermediate textile products (e.g., slivers or rovings). The water-repellent compositions of this disclosure are particularly effective in making textile products (e.g., synthetic fibers) water-repellent.
[0307] The fibers that make up the textile product may be natural fibers, synthetic fibers, semi-synthetic fibers, regenerated fibers, or inorganic fibers. Fibers may be used individually or in combination of two or more types.
[0308] Examples of natural fibers include cellulose fibers such as cotton, flax, and pulp, as well as chitin, chitosan, wool, and silk. Specific examples of wood pulp include mechanical pulps such as groundwood pulp (GP), pressured groundwood pulp (PGW), and thermomechanical pulp (TMP); chemical pulps such as high-yield unbleached softwood kraft pulp (HNKP; N material), bleached softwood kraft pulp (NBKP; N material, NB material), unbleached hardwood kraft pulp (LUKP; L material), and bleached hardwood kraft pulp (LBKP, L material); recycled paper pulp such as deinking pulp (DIP) and waste pulp (WP), and semi-chemical pulp (CP).

[0310] Alternatively, the textile product may be leather. The manufacturing polymer may be applied to the leather in the form of an aqueous solution or aqueous emulsion at various stages of leather processing, for example, during the wetting process or during the finishing process, in order to make the leather hydrophobic and oleophobic. Alternatively, the textile product may be paper. The manufacturing polymer may be applied to pre-formed paper, or it may be applied at various stages of papermaking, for example, during the drying period of the paper.
[0311] "Treatment" means applying the water-repellent composition to a substrate by immersion, spraying, coating, etc. Through treatment, the non-fluorine copolymer (A) and isocyanate derivative (B), which are the active ingredients of the water-repellent composition, penetrate into the interior of the substrate and / or adhere to the surface of the substrate. In other words, through treatment, a substrate (e.g., a textile product) to which the non-fluorine copolymer (A) and isocyanate derivative (B) of the water-repellent composition of this disclosure are attached is obtained.
[0312] [Pretreatment of textile products] Textile products may be pre-treated before being treated with the water-repellent composition of this disclosure. Pre-treating the textile products can impart excellent fastness to the textile products after treatment with the water-repellent composition.
[0313] Examples of pretreatments for textile products include cationization by reaction with reactive quaternary ammonium salts, anionization by sulfonation, carboxylation, phosphorylation, etc., acetylation, benzoylation, carboxymethylation, grafting, tannic acid treatment, and polymer coating after anionization.
[0314] The method for pre-treating textile products is not limited, but conventionally known methods can be used. This may involve dispersing and diluting the pre-treatment solution in an organic solvent or water as needed, applying it to the surface of the textile product by known methods such as immersion coating, spray coating, or foam coating, and then drying it. The pH and temperature of the pre-treatment solution may be adjusted according to the desired degree of treatment. As an example of a method for pre-treating textile products, a method of pre-treating textile products with a hydrocarbon-based water repellent will be described in detail.

[0317] Fibers containing the above-mentioned specific functional groups (hereinafter sometimes referred to as "functional group-containing fibers") can be prepared, for example, by the following method. (i) A compound having the above-mentioned specific functional group is attached to the fiber material. The attachment of the compound may be such that a portion of the compound and a portion of the fiber are chemically bonded, to the extent that a sufficient amount of the above-mentioned specific functional group remains. (ii) Prepare a fiber in which the above-mentioned specific functional group is directly introduced into the material constituting the fiber.
[0318] (i) For example, a functional group-containing fiber can be obtained by a functional group introduction step in which the fiber material is treated with a pretreatment solution containing one or more compounds having the above-mentioned specific functional group.
[0319] There are no particular restrictions on the material of the fiber material, and examples include natural fibers such as cotton, linen, silk, and wool; semi-synthetic fibers such as rayon and acetate; synthetic fibers such as polyamide (nylon, etc.), polyester, polyurethane, and polypropylene; and composite fibers and blended fibers thereof. The fiber material may take any form, such as fibers (tow, sliver, etc.), yarn, knitted fabrics (including interwoven fabrics), woven fabrics (including interwoven fabrics), nonwoven fabrics, and paper.
[0320] In this embodiment, from the viewpoint of obtaining good water repellency in the resulting textile product, it is preferable to use a fiber material containing polyamide and polyester as a base material. In particular, it is preferable to use nylon such as nylon 6 and nylon 6,6, polyester such as polyethylene terephthalate (PET), polytrimethyl terephthalate, and polylactic acid, and mixed fibers containing these.
[0321] The above -SO3M 1 As a compound having this property, phenolic polymers can be used. Examples of such phenolic polymers include those containing at least one compound represented by the following general formula.

[0327] The above-COOM 2 Examples of compounds having this property include polycarboxylic acid polymers.
[0328] As polycarboxylic acid polymers, for example, polymers synthesized by conventionally known radical polymerization methods using acrylic acid, methacrylic acid, maleic acid, etc. as monomers, or commercially available polymers can be used.
[0329] One method for producing polycarboxylic acid polymers is to add a radical polymerization initiator to an aqueous solution of the monomer and / or its salt, and heat the reaction at 30 to 150°C for 2 to 5 hours. At this time, alcohols such as methanol, ethanol, isopropyl alcohol, or aqueous solvents such as acetone may be added to the aqueous solution of the monomer and / or its salt. Examples of radical polymerization initiators include persulfates such as potassium persulfate, sodium persulfate, and ammonium persulfate, redox polymerization initiators using combinations of persulfates and sodium bisulfite, hydrogen peroxide, and water-soluble azo polymerization initiators. These radical polymerization initiators may be used alone or in combination of two or more. Furthermore, during radical polymerization, a chain transfer agent (e.g., octyl thioglycolate) may be added to adjust the degree of polymerization.
[0330] In radical polymerization, copolymerizable monomers can be used in addition to the monomers mentioned above. Examples of copolymerizable monomers include vinyl monomers such as ethylene, vinyl chloride, and vinyl acetate, as well as acrylamide, acrylates, and methacrylates. Acrylates and methacrylates are preferably those having a hydrocarbon group with 1 to 3 carbon atoms, which may have substituents such as hydroxyl groups. Examples of such acrylates or methacrylates include methyl acrylate, methyl methacrylate, ethyl acrylate, ethyl methacrylate, 2-hydroxyethyl acrylate, 2-hydroxyethyl methacrylate, propyl acrylate, and propyl methacrylate. These copolymerizable monomers may be used individually or in combination of two or more.
[0331] The carboxyl groups in the polycarboxylic acid polymer may be free or neutralized by alkali metals or amine compounds. Examples of alkali metals include sodium, potassium, and lithium, while examples of amine compounds include ammonia, monoethanolamine, diethanolamine, and triethanolamine.
[0332] The weight-average molecular weight of the polycarboxylic acid polymer is preferably 1,000 to 20,000, and more preferably 3,000 to 15,000, from the viewpoint of obtaining good water repellency in the resulting textile product.
[0333] For polycarboxylic acid polymers, commercially available products such as "NeoCrystal 770" (manufactured by Nikka Chemical Co., Ltd., product name) and "Cellopol PC-300" (manufactured by Sanyo Chemical Industries, Ltd., product name) can be used.
[0334] The above - OP(O)(OX 1 )(OX 2 Examples of compounds having the following general formula include phosphate ester compounds. [ka] [where, X 1 or X 2 This is synonymous with the above, X 3 This represents an alkyl group with 1 to 22 carbon atoms.
[0335] As the phosphate ester compounds mentioned above, phosphate monoesters, diesters, and triesters in which the alkyl ester portion has an alkyl group having 1 to 22 carbon atoms, as well as mixtures thereof, can be used.
[0336] From the viewpoint of obtaining good water repellency in the resulting textile product, it is preferable to use lauryl phosphate esters and decyl phosphate esters.
[0337] For the phosphate ester compound, commercially available products such as "Phosphanol ML-200" (manufactured by Toho Chemical Industry Co., Ltd., trade name) can be used.
[0338] The pretreatment solution containing one or more compounds having the above-mentioned specific functional groups can, for example, be an aqueous solution of the compounds described above. The pretreatment solution may also contain acids, alkalis, surfactants, chelating agents, etc.
[0339] Methods for treating fibrous materials with the above-mentioned pretreatment solution include, for example, padding, immersion, spraying, and coating. For padding, for example, methods using padding equipment described on pages 396-397 of the Dictionary of Textile Dyeing and Processing (published in 1963 by Nikkan Kogyo Shimbun) and pages 256-260 of Color Dyeing Chemistry III (published in 1975 by Jikkyo Shuppan Co., Ltd.) can be used. For coating, for example, methods using coating machines described on pages 473-477 of the General Catalog of Dyeing and Finishing Equipment (published in 1981 by Senryo-sha) can be used. For immersion, for example, methods using batch-type dyeing machines described on pages 196-247 of the General Catalog of Dyeing and Finishing Equipment (published in 1981 by Senryo-sha) can be used, and liquid flow dyeing machines, air flow dyeing machines, drum dyeing machines, winch dyeing machines, washer dyeing machines, cheese dyeing machines, etc. can be used. Examples of spray treatments include air sprays that atomize the treatment solution using compressed air, and air sprays that use a hydraulic atomization system. The concentration of the treatment solution and the treatment conditions such as heat treatment after application can be adjusted as appropriate, taking into account the purpose, performance, and other conditions. If the pretreatment solution contains water, it is preferable to dry it to remove the water after it has been applied to the fiber material. There are no particular restrictions on the drying method, and either a dry heat method or a wet heat method may be used. There are no particular restrictions on the drying temperature, but for example, drying at room temperature to 200°C for 10 seconds to several days is sufficient. If necessary, after drying, heat treatment may be performed at a temperature of 100 to 180°C for about 10 seconds to 5 minutes.
[0340] Furthermore, if the fiber material is to be dyed, the pretreatment with the pretreatment solution may be performed before dyeing or in the same bath as the dyeing. However, if reducing soaping is performed, there is a risk that the compounds having the specific functional groups (e.g., phenolic polymer compounds, etc.) that have been adsorbed during the process may be removed. Therefore, it is preferable to perform the pretreatment after reducing soaping following dyeing.
[0341] The treatment temperature during the immersion process can be 60 to 130°C. The treatment time can be 5 to 60 minutes.
[0342] In the functional group introduction step using the pretreatment solution, it is preferable to treat the material in such an amount that the amount of compound having the specified functional group attached is 1.0 to 7.0 parts by weight per 100 parts by weight of the fiber material. Within this range, a high level of both durable water repellency and texture can be achieved.
[0343] The pretreatment solution is preferably adjusted to a pH of 3-5. pH adjustment can be done using pH adjusting agents such as acetic acid or malic acid.
[0344] The pretreatment solution may also contain salt to effectively adsorb the compound having the above-mentioned specific functional group onto the fiber material through a salting-out effect. Examples of salts that can be used include sodium chloride. Examples include sodium carbonate, ammonium sulfate, and sodium sulfate.
[0345] In the functional group introduction step using a pretreatment solution, it is preferable to remove any compounds having the specified functional groups that have been excessively treated. One method of removal is washing with water. By ensuring sufficient removal, it is possible to suppress the inhibition of water repellency development in the subsequent water-repellent treatment, and in addition, the texture of the resulting textile product will be improved. Furthermore, it is preferable to thoroughly dry the resulting functional group-containing fibers before contacting them with a hydrocarbon-based water repellent.
[0346] (ii) Examples of fibers in which the above-mentioned specific functional groups are directly introduced into the material constituting the fiber include cationic dyeable polyester (CD-PET).
[0347] From the viewpoint of obtaining good water repellency in the resulting textile product, the functional group-containing fibers preferably have a surface zeta potential of -100 to -0.1 mV, and more preferably -50 to -1 mV. The surface zeta potential of the fibers can be measured, for example, using the zeta potential / particle size measurement system ELSZ-1000ZS (manufactured by Otsuka Electronics Co., Ltd.).
