Summary of the Invention

Problems to be Solved by the Invention

[0004] The market for fiber treatment agents has been expanding year by year. In recent years, in addition to the basic function of imparting texture (softness) to fiber products, fiber treatment agents (fragranced fiber treatment agents) having a function of imparting various scents to fiber products have been sold. However, the present inventor has found that when a fiber product treated with a conventional fragranced fiber treatment agent is dried in a dryer, the scent flies away during the drying process, and the scent of the fiber product after drying is weak (the residual fragrance property is low). Furthermore, the inventors have found that when textile products treated with a conventional fragrance-imbuing fiber treatment agent are dried in a dryer, uneven fragrance (unevenness) and stains caused by the treatment agent occur on the textile products. [Means for solving the problem]

[0005] As a result of diligent investigation into the aforementioned problems, the inventors have found that the aforementioned problems can be solved by treating textile products with a textile treatment agent comprising (A) a cationic surfactant and / or a silicone compound, (B) a nonionic surfactant (excluding the silicone compound), and (C) a fragrance, in predetermined amounts.

[0061] [Method of using the fiber treatment agent composition] The textile treatment agent composition is used to treat textile products that are subjected to drying using a dryer. The processing method is not particularly limited as long as it allows the fiber treatment agent composition to be applied to the textile product. Examples of processing methods include a method of applying a fiber treatment agent composition to a textile product by spraying it, a method of applying a fiber treatment agent composition stored in a container or tank equipped with a discharge port to a textile product in a shower-like manner, and a method of immersing a textile product in a fiber treatment agent composition accumulated in a container or tank. In particular, from the viewpoint of uniformly treating textile products, a method of storing the textile treatment agent composition in a spray container or tank and spraying it onto the textile products manually or electrically is preferred. The fiber treatment is carried out such that the ratio of the volume (mL) of the fiber treatment agent composition to the mass (g) of the fiber product (fiber treatment agent composition (mL) / fiber product (g)) is 0.01 to 0.5, preferably 0.02 to 0.3, and more preferably 0.02 to 0.1. When the aforementioned ratio is 0.01 or greater, the desired effect can be obtained for the textile product as a whole. If the aforementioned ratio is 0.5 or less, it is possible to prevent problems such as poor drying caused by textile products becoming too wet.

[0062] Specific examples of the treatment method by spraying include the following (1) to (3). (1) The textile product that has been washed and dewatered is sprayed with the textile treatment agent composition. Then the treated textile product is dried in a dryer. When using a washing machine with a drying function (such as a drum-type washer-dryer), it is preferable to spray the textile product with the textile treatment agent composition after removing it from the washing machine and return it to the washing machine for drying. (2) Spray the textile product that has not been washed or dewatered (including the textile product before being subjected to washing and dewatering) with a textile treatment agent. Then dry the treated textile product in a dryer. (3) The textile product is sprayed with the textile treatment agent composition while it is being dried in the dryer.

[0063] Textile products treated with the textile treatment agent composition are subjected to drying in a dryer. There are no restrictions on the type of dryer. Examples of dryers include washer-dryers with drying functions, standalone clothes dryers, bathroom dryers, and closet-type clothes dryers. An example of a washer-dryer is a drum-type washer-dryer. The average temperature of the drying process is not particularly limited, but is preferably 30°C or higher, more preferably 35-65°C. When the average temperature of the drying process is within this range, sufficient drying effect can be obtained while minimizing damage to the textile product.

[0064] [Textile products] The material of the fibers to which the fiber treatment agent composition is applied is not particularly limited. Examples of fiber materials include natural fibers such as cotton, wool, and linen; synthetic fibers such as polyester, nylon, and acrylic; semi-synthetic fibers such as acetate; regenerated fibers such as rayon, Tencel, and polynosic; and blends, woven, and knitted products of these materials.

The composition of each fiber treatment agent composition is shown in Table 1 below. The content values ​​in Table 1 represent the content (mass%) relative to the total mass of the fiber treatment agent composition.

[0072] [Evaluation of fiber treatment agent compositions] Following the procedure described below, textile products were treated with a textile treatment agent composition, dried in a dryer, and then their properties (residual fragrance, uneven fragrance, staining, texture (non-stickiness), and texture (non-stickiness)) were evaluated.

[0073] [Processing of textile products] A textile product (cotton undershirt) was subjected to washing and spin-drying processes (according to the standard cycle of the washing machine) in a drum-type washer-dryer (NAVX7600L, manufactured by Panasonic). For washing, a commercially available detergent, "Top Platinum Clear" (manufactured by Lion Corporation, standard usage amount), was used. After removing the textile products from the washing and drying machine and loosening them, each textile treatment agent composition was uniformly sprayed onto the products. A trigger spray container (Styleguard, manufactured by Lion Corporation) was used for spraying. Table 1 shows the mass (g) of the textile products subjected to fiber treatment (textile products before washing and dewatering), the volume (mL) of the fiber treatment agent composition used for fiber treatment, and the ratio of the volume of the fiber treatment agent composition to the mass of the textile products (textile treatment agent composition (mL) / textile products (g)). The processed textile products were returned to the aforementioned washer-dryer and subjected to drying (according to the washer-dryer's automatic cycle). The average drying temperature was 40.2°C.

[0074] [Fragrance lingering] The fragrance of textile products after drying was evaluated according to the following evaluation criteria. The evaluation was conducted by five expert panelists. The average score of the five panelists (calculated to one decimal place) was applied to the following judgment criteria to evaluate the "fragrance of textile products after drying (lingering fragrance)". The results are shown in the "Lingering Fragrance" column of Table 1. ○ and ○○ were considered passing grades. <Evaluation Criteria> 5: The fiber treatment agent composition has a very strong scent. 4: The fiber treatment agent composition has a strong fragrance. 3: The fiber treatment agent composition has a pleasant fragrance. 2: The fragrance of the fiber treatment agent composition is noticeable. 1: The fiber treatment agent composition has a slight fragrance. 0: The fiber treatment agent composition has no scent. <Judgment criteria> ○: The average score of the 5 evaluators is 4.5 or higher. 〇〇: The average score of the 5 evaluators is between 3.0 and 4.5 points. ○: The average score of the 5 evaluators is between 2.0 and 3.0. ×: The average score of the 5 evaluators is less than 2.0. For textile treatment agent compositions with an average score of 4.5 or higher, some panelists evaluated them as having "a good scent that remains sufficiently," while others evaluated them as having "a scent that is too strong." Therefore, they were given a lower rating of "○" than "○○."

[0075] [Scent may vary] The fragrance of the textile product was evaluated at eight locations (four on the front and four on the back) after drying. The fragrance evaluation was carried out according to the same evaluation criteria as for [fragrance retention evaluation]. The evaluation results were applied to the following criteria to evaluate the "fragrance unevenness of the textile product after drying". The results are shown in the "fragrance unevenness" column of Table 1. ○ and ○○ were considered passing grades. <Judgment criteria> 〇〇: Six or more out of eight areas of the textile product received the same evaluation score. ○: 3 to 5 out of 8 textile products received the same evaluation score. ×: Two or fewer of the eight areas in the textile product category have the same rating.

[0076] [Stains on textile products] Stains (caused by the fiber treatment agent composition) on textile products after drying were visually evaluated according to the following criteria. The results are shown in the "Stains" column of Table 1. ○ indicates a pass. <Judgment criteria> ○: No stains remain ×: Stain remains

[0077] [Texture (stickiness)] The texture of textile products after drying, in terms of "stickiness," was evaluated according to the following criteria. Stickiness was evaluated by placing a hand on the surface of the textile product and sliding the hand horizontally. Textile products subjected to drying after being treated with deionized water instead of a textile treatment agent composition were used as a control group. The results are shown in the "Texture (non-stickiness)" column of Table 1. ○ and ○○ were considered acceptable. <Judgment criteria> 〇〇: Compared to water treatment, the level of stickiness is equal to or better. ○: Slightly stickier compared to water treatment. ×: Clearly sticky compared to water treatment.

[0078] [Texture (softness / smoothness)] The texture of the textile products after drying was evaluated in terms of "softness and smoothness" according to the following criteria. Softness was evaluated by placing a hand on the surface of the textile product and pressing it vertically. Smoothness was evaluated by placing a hand on the surface of the textile product and sliding the hand horizontally across it. Textile products subjected to drying after being treated with deionized water instead of a textile treatment agent composition were used as a control group. The results are shown in the "Texture (Softness / Smoothness)" column of Table 1. ○ and ○○ were considered acceptable. <Judgment criteria> 〇〇: Softer and smoother compared to water treatment. ○: Softer or smoother compared to water treatment. ×: Softness and smoothness are equivalent to or less than that achieved with water treatment.
