However, as textile products are repeatedly worn and washed, it can become difficult to impart the desired fragrance to them. This is thought to be because, for example, repeated use of textile products can lead to the presence of malodorous odors from bacteria that may be present on the textile products, making it impossible to impart the intended fragrance to the textile products. In other words, the quality of the fragrance (derived from the fragrance components) imparted to textile products treated with a textile product treatment agent containing fragrance components deteriorates. The present invention aims to provide a textile product treatment composition that can effectively reduce unpleasant odors (e.g., odors originating from bacteria) generated from textile products and improve the quality of the fragrance (derived from fragrance components) imparted to the textile products. [Means for solving the problem] 【0007】 In one embodiment, the present invention provides a textile product treatment composition containing (A) particles having an average particle diameter of 1 nm to 10 μm, which contain the following component (a) and component (b) [hereinafter referred to as component (A)], (B) microcapsules containing a fragrance component [hereinafter referred to as component (B)], and water. (a) Components: One or more organic compounds selected from (a-1) to (a-6) below. (a-1) Aliphatic alcohols with 10 to 24 carbon atoms (a-2) Fatty acids with 10 to 24 carbon atoms (a-3) Aliphatic glyceryl ether having an aliphatic hydrocarbon group with 10 to 24 carbon atoms (a-4) Esters of fatty acids with 10 to 24 carbon atoms and polyhydric alcohols (a-5) A quaternary ammonium salt in which one to three groups bonded to the nitrogen atom are hydrocarbon groups having 10 to 24 carbon atoms, and the remaining groups are alkyl groups having 1 to 3 carbon atoms or hydroxyalkyl groups having 1 to 3 carbon atoms. (a-6) Polyoxyalkylene alkyl or alkenyl ether having an alkyl or alkenyl group with 10 to 24 carbon atoms. (b) Ingredients: Water-insoluble inorganic antibacterial agent 【0008】 In another embodiment, the present invention provides a method for treating textile products, comprising bringing a textile product into contact with a treatment liquid containing (A) particles having an average particle diameter of 1 nm to 10 μm containing (A) and (B) components [hereinafter referred to as (A) components], (B) microcapsules containing fragrance components [hereinafter referred to as (B) components], and water. [Effects of the Invention] 【0009】 The textile product treatment composition of the present invention, and the method for treating textile products using the same, can effectively reduce unpleasant odors (e.g., odors originating from bacteria) generated from textile products and improve the quality of the fragrance (derived from fragrance components) imparted to the textile products. [Modes for carrying out the invention] 【0010】 The reason why the textile product treatment composition of the present invention was able to effectively reduce unpleasant odors (e.g., odors originating from bacteria, etc.) generated from textile products and improve the quality of the fragrance (derived from fragrance components) imparted to the textile products is not entirely clear, but it is presumed to be as follows. 【0011】 Generally, water-insoluble inorganic antibacterial agents, which are component (b), have poor dispersibility in water. Therefore, even if an aqueous liquid containing component (b) is brought into contact with a textile product, the dispersion state of the aqueous liquid is undesirable, and it is predicted that the textile product will have difficulty obtaining the effects expected from component (b). The present invention is thought to enable the efficient attachment of component (b) to the textile product and the effective imparting of the functions of component (b) to the textile product by bringing specific particles (A) containing component (b) into contact with the textile product, which contain a specific organic compound, which is component (a). 【0012】 Furthermore, for example, when a textile product treatment composition containing a cationic compound is used to treat textile products that have anionic surfactants present, such as detergent residue, during the washing process, the effects of the cationic compound (e.g., antibacterial effect, effect of suppressing the generation of bacteria-derived odors, etc.) may not be fully exhibited. In such cases, unpleasant odors generated from the textile product (e.g., odors derived from bacteria) may be dispersed along with the fragrance, causing further unpleasant odors in the textile product, and the full potential of the fragrance may not be realized. 【0013】 The textile product treatment composition of the present invention is believed to be able to treat textile products that contain anionic surfactants, such as rinse residue, without being affected by the anionic surfactants, and, due to component (b), suppress the generation of odors, for example, caused by bacteria, allowing the full potential of the fragrance to be realized, that is, it can improve the quality of the fragrance (derived from fragrance components) imparted to the textile product. However, the present invention is not limited to the above-described mechanism of action. 【0014】 [Textile product treatment agent composition] The textile product treatment agent composition of the present invention may, in one embodiment, contain component (A), component (B), and water. 【0015】 <(A) component> The organic compound of component (a) that constitutes component (A) may be one or more types selected from (a-1) to (a-6) below as one form. 【0016】 (a-1) Aliphatic alcohols with 10 to 24 carbon atoms (a-2) Fatty acids with 10 to 24 carbon atoms (a-3) Aliphatic glyceryl ether having an aliphatic hydrocarbon group with 10 to 24 carbon atoms (a-4) Esters of fatty acids with 10 to 24 carbon atoms and polyhydric alcohols (a-5) A quaternary ammonium salt in which one to three groups bonded to the nitrogen atom are hydrocarbon groups having 10 to 24 carbon atoms, and the remaining groups are alkyl groups having 1 to 3 carbon atoms or hydroxyalkyl groups having 1 to 3 carbon atoms.

The fragrance (B1) may preferably be a composition containing a plurality of fragrance compounds including fragrance compound (b1). 【0060】 In this invention, the LogP value is a coefficient that indicates the affinity of an organic compound for water and 1-octanol. The 1-octanol / water partition coefficient P is the ratio of the equilibrium concentrations of the compound in each solvent at the partition equilibrium when a trace amount of the compound is dissolved as a solute in a two-phase solvent of 1-octanol and water, and is generally expressed in the form of its logarithm LogP with respect to base 10. LogP values ​​for many compounds have been reported, and many values ​​are listed in databases available from Daylight Chemical Information Systems, Inc. (Daylight CIS), etc., so they can be referred to. If there is no measured LogP value, it can be calculated using a program such as "CLOGP" available from Daylight CIS. If a measured LogP value is available, this program outputs the "calculated LogP (CLogP)" value calculated by Hansch, Leo's fragment approach along with the measured LogP value. When multiple fragrances are included, the CLogP value of the fragrance mixture can be obtained by multiplying the CLogP value of each fragrance by its volume ratio in the fragrance mixture and summing them up. 【0061】 The fragment approach is based on the chemical structure of the compound, taking into account the number of atoms and the type of chemical bonds (cf. A. Leo, Comprehensive Medicinal Chemistry, Vol.4, C. Hansch, PG Sammens, JB Taylor and CA Ramsden, Eds., p.295, Pergamon Press, 1990). This CLogP value can be used in place of the measured LogP value when selecting a compound. In this invention, if a measured LogP value is available, that is used; otherwise, the CLogP value calculated by the program CLOGP v4.01 is used. 【0062】 Furthermore, component (B1) may, in another form, be one or more selected from the fragrance compounds described later, or it may be a fragrance composition containing two or more.

[(D) component] Inorganic salts: Calcium chloride [(E) component] (E1-1): Quaternary ammonium compound synthesized by the following synthesis method: Surfactant described in Japanese Patent Publication No. 2018-44256 【0148】 <Synthesis Example 1: Synthesis of Component (E1-1)> A condensate mainly composed of N,N-dialkanoyloxyethyl-N-hydroxyethylamine was obtained by dehydration esterification reaction of a fatty acid with an acid value of 206.9 mgKOH / g derived from palm oil with triethanolamine at a reaction molar ratio of 1.65 / 1 (fatty acid / triethanolamine). Next, the amine value of this condensate was measured, and quaternization was performed using 0.95 equivalents of dimethyl sulfuric acid on the condensate according to a standard method to obtain a quaternary ammonium salt mixture (E-1) mainly composed of N,N-dialkanoyloxyethyl-N-hydroxyethyl-N-methylammonium methyl sulfate and containing 10% by mass of ethanol. However, the term "alkanoyl" here includes not only saturated fatty acids but also residues derived from unsaturated fatty acids, such as alkenoyl, because alkanoyl is a fatty acid residue from the palm oil raw material. The manufacturing procedure and reaction conditions described above were carried out in accordance with Synthesis Example 2 of Japanese Patent Publication No. 2010-209493. 【0149】 (E1-2): Benzalkonium chloride (alkyl(C12-16) benzyldimethylammonium chloride, Sanizol B-50), manufactured by Kao Corporation. 【0150】 <Other ingredients> • Fragrance: Non-encapsulated fragrance as listed in Table 3 below • Preservative: 1,2-Benzisothiazolin-3-one (Proxel BDN®, manufactured by Arch Chemical Japan Co., Ltd.) Antifoaming agent: DOW CORNING TORAY 1315 ANTIFOAM CONCENTRATE (trademark), manufactured by Toray Dow Corning Corporation. Chelating agent: Trisodium methylglycine diacetate (Trilon M Liquid®), BASF Japan Ltd. (The amount of trisodium methylglycine diacetate used was adjusted to match the value in Table 2.) 【0151】 [Method for producing a textile product treatment agent composition] (1) Manufacturing of component (A) Each component listed in Table 1 was mixed in the amounts listed in Table 1 while being heated to 60°C. Water heated to 60°C was then added to prepare a suspension. The suspension was put into a high-pressure emulsifier (product name "Econizer LABO02", manufactured by Sanmaru Machinery Industry Co., Ltd.) and homogenized, then cooled to 40°C to produce aqueous dispersions 1 to 3 containing the particles (A1) to (A3), which are component (A). Each of the obtained aqueous dispersions containing the particles of component (A) was adjusted with ion-exchanged water to a solid content of 0.03% by mass, and the average primary particle diameter (number-average particle diameter) was calculated by measuring with a ZETASIZER (Nano-ZS) (manufactured by Malvern). The results are shown in Table 1. 【0152】 [Table 1] 【0153】 (2) Method for producing textile product treatment agent composition Each textile product treatment agent composition was prepared by mixing the components listed in Table 2 in the amounts specified in Table 2. In the table, the composition of each component is expressed as the mass % of the pure content of each component. The content of component (A) is the total content (pure content) of components (a), (b), and (c) in Table 1. The content of component (B) is the total amount (pure content) of the fragrance compounds encapsulated in the fragrance-encapsulated microcapsules in the fragrance-encapsulated microcapsule slurry. The pH (25°C) and viscosity of Examples 1 to 3 were confirmed to be within the ranges described above. The measurement methods used were those described in the main text. 【0154】 [Evaluation of textile product treatment agent compositions] (1) Preparation of test fabrics 1 and 2 Deionized water, sterilized by boiling at 100°C for 120 minutes, was mixed with calcium chloride dihydrate and magnesium chloride hexahydrate to achieve a hardness of 5 DH° (Ca / Mg = 7 / 3, mass ratio). Sodium bicarbonate was then added to achieve an alkalinity of 80 mg / L, and the pH was further adjusted to 7 with hydrochloric acid. 600 g of the prepared water and 3 g of a 1% by mass aqueous solution of an anionic surfactant (linear alkylbenzene sulfonate with 10-14 carbon atoms) were placed in a stirring-type cleaning power tester (turgotometer, MS-8212, manufactured by Ueshima Seisakusho). 15 g each of a used towel, cut into 6 cm x 6 cm pieces, and 15 g each of a 6 cm x 6 cm piece of cotton knit fabric (cotton fabric 2003 purchased from Tanigashira Shoten) (total 30 g) were added, and the mixture was stirred for 12 minutes. After stirring, the fabric was dewatered for 2 minutes in a twin-tub washing machine (HITACHI P-H35L). The pre-washed test fabric was again placed in an agitator-type washing machine, and 600g of the prepared water and 0.14g of the textile product treatment agent composition described in Table 2 were added. The fabric was agitated at 85rpm for 5 minutes. After agitation, the fabric was dewatered again for 2 minutes in a twin-tub washing machine and dried flat in a constant temperature room (30°C, 70%) for 12 hours. The textile product treatment agent composition described in Table 2 was added immediately after agitation. The treated used towel was used as test fabric 1, and the treated cotton knit fabric was used as test fabric 2 for the evaluation described below. 【0155】 [(2) Evaluation Method] A piece of used towel fabric (Test Fabric 1) processed using the method described above was evaluated by five experienced evaluators using the following two evaluation scales and criteria. The values ​​determined by consensus among the five experts are shown in the table. Test Fabric 2, processed using the method described above, was used as the reference fabric for the evaluation. 【0156】 <Fragrance Evaluation> 5: The same scent as test cloth 2 is strongly present, and overall, it smells very nice. 4: The same scent as test cloth 2 was detected, and overall it smelled pleasant. 3: The same scent as test cloth 2 is present, but a foul odor (likely from bacteria) is also present, making the overall smell somewhat unpleasant. 2: A slight scent similar to that of test cloth 2 was detected, and a foul odor (likely from bacteria) was also present, resulting in an overall unpleasant smell. 1: The same scent as test cloth 2 was not detected, and it was strongly perceived as a foul odor. 【0157】 [Table 2] 【0158】 In the fragrance evaluation, the textile product treatment compositions of Examples 1-3 in Table 2 showed a reduction in malodor, along with a pure fragrance derived from the fragrance components. On the other hand, while the textile product treatment compositions of Comparative Examples 1-5 did emit fragrance, the presence of malodor resulted in a perceived difference in fragrance profile. 【0159】 [Table 3] 【0160】 Table 4 shows example formulations of suspensions of aqueous dispersions 4-6 containing each particle (A4)-(A6), which are component (A), and can be manufactured by the same method as the suspension manufactured in Table 1. Similar effects can be obtained by replacing aqueous dispersions 1-3 of the textile product treatment agent composition in Table 2 with aqueous dispersions 4-6. 【0161】 [Table 4]
