Examples of spray containers include trigger spray containers (direct pressure type or pressure-accumulating type) and dispenser spray containers. Examples of trigger spray containers include those described in Japanese Patent Publication No. 9-268473, Japanese Patent Publication No. 9-256272, and Japanese Patent Publication No. 10-76196. Examples of dispenser spray containers include those described in Japanese Patent Publication No. 9-256272. Furthermore, the liquid composition for fiber processing of the present invention can be stored in a plastic container. Examples of plastic containers include bottles and refillable standing pouches. Examples of standing pouches include those described in Japanese Patent Application Publication No. 2000-72181, but in terms of material, a two-layer structure with 100-250 μm linear low-density polyethylene as the inner layer and 15-30 μm stretched nylon as the outer layer, or a three-layer structure with 15 μm stretched nylon as the intermediate layer and 15 μm stretched nylon as the outer layer is preferred in terms of storage stability. The textile products to which the liquid composition for fiber treatment of the present invention is used are not particularly limited, but include, for example, dress shirts, T-shirts, polo shirts, blouses, underwear, functional innerwear, chinos, suits, slacks, skirts, stockings, tights, jackets, coats, knitwear, jeans, pajamas, cushions, seat cushions, sofas, pillowcases, sheets, bed pads, pillows, futons, bed covers, blankets, mattresses, cloth masks, shoes, etc. The materials of the target textile products are also not particularly limited, but include, for example, 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 various fibers. [Examples]

[0028] The present invention will be described in more detail below with reference to examples, but the scope of the present invention is not limited thereto. In the examples, all component amounts are expressed in mass % (on a pure content basis unless otherwise specified).

[0029] [(A) component] The following A-1 was used. A-1: Glycerin (manufactured by Sakamoto Pharmaceutical Co., Ltd.)

[0030] [(B) Component] The following B-1 to B-3 were used. • B-1: Polyether-modified silicone (DOWSIL SH3771M Fluid, manufactured by Dow-Toray, HLB13) • B-2: Polyether-modified silicone (DOWSIL SH3775M Fluid, manufactured by Dow-Toray, HLB5) • B-3 (Comparative Example): Dimethicone (KF-96A, manufactured by Shin-Etsu Silicone Co., Ltd.)

[0031] [(C) component] The following C-1 to C-3 were used. • C-1: Polyethylene glycol (PEG600, manufactured by Sanyo Chemical Industries, Ltd.) • C-2: Propylene glycol (reagent, Wako Pure Chemical Industries) • C-3: Ethanol (reagent, Wako Pure Chemical Industries)

[0032] [Common ingredients] • Polyoxyethylene hydrogenated castor oil (EO40) 1.0%: NIKKOL HCO40 (manufactured by Nikko Chemical Co., Ltd.) • Fragrance composition 0.1%: See Table 1 below. • Phenoxyethanol 1.0%: Newpol EFP (manufactured by Sanyo Chemical Industries, Ltd.) ·Water remainder

[0033] [Table 1]

[0034] [Method for preparing a liquid composition for fiber processing] A liquid composition for fiber treatment was prepared by mixing components (B) and (C), stirring well, then mixing in component (A) and other common components and stirring further (Examples 1-14 and Comparative Examples 1-4).

[0035] [Evaluation method for liquid compositions for fiber processing] <Permeability> 40g of the composition prepared according to the "Method for Preparing Liquid Composition for Fiber Treatment" described above was filled into a PS6 bottle, and wool serge cut into 2cm squares was gently placed on the liquid surface using tweezers. After placement, the time until the wool serge completely settled was measured and evaluated according to the following criteria. The results are shown in the "Permeability" column in Table 2 below. (Evaluation Criteria) ○○: Settles in less than 3 minutes ○: Settlement occurs between 3 and 10 minutes. ×: No sinking after 10 minutes.

[0036] <Fuzziness> The composition prepared according to the "Method for Preparing Liquid Compositions for Fiber Treatment" described above was applied to cotton knit fabric cut into 5cm squares to achieve a 20% owf (owf) concentration. The surface after application was repeatedly adhered to and peeled off with masking tape to create a fluffy texture. The appearance of the evaluation fabric after fluffing was evaluated by five evaluators according to the evaluation criteria below. The results are shown in the "Fluffiness" column of Table 2 below. (Evaluation Criteria) ○○: 5 out of 5 judged that the treated fabric produced less fluff than the untreated fabric. ○: 3 out of 5 judged that the fabric produced less fluff than the untreated fabric. ×: 2 out of 5 judged that the fabric produced less fluff than the untreated fabric. (Untreated fabric is fabric that has not been coated with the composition prepared according to the "Method for Preparing Liquid Compositions for Fiber Treatment" described above.)

[0037] <Spray properties> The composition prepared according to the "Method for Preparing Liquid Compositions for Fiber Treatment" described above was placed in a dispenser spray (Styleguard Portable, manufactured by Lion Corporation), placed on a flat surface, and the liquid composition was sprayed. The distance reached by the droplets was measured and the composition was visually evaluated according to the following criteria. The results are shown in the "Spray Characteristics" section of Table 2 below. (Evaluation Criteria) 〇○: Droplets are located more than 120cm away. ○: Droplets are present at a distance of 100cm or more. ×: No droplets visible at a distance of 100cm or more.
