< ingredient (A) >

(A) The component (c) is at least 1 selected from an anionic surfactant (hereinafter also referred to as "component (A1)") and a nonionic surfactant (hereinafter also referred to as "component (A2)").

(A) The component (B) can impart permeability and detergency to a fiber product to the composition. The component (A) facilitates penetration of the component (B) described later into the fibers, and improves the deodorizing effect. Further, since the component (a) has detergency, even if the fiber product is merely immersed in the treatment liquid, the fiber product can be cleaned, and odor generation from the fiber product can be suppressed.

Examples of the component (A1) include sulfonic acid types such as linear alkylbenzene sulfonic acid or a salt thereof, α -olefin sulfonate (α -olefin sulfonate), internal olefin sulfonate (internal olefin sulfonate), and (alk) alkane sulfonate having an alkyl group; linear or branched alkyl sulfate ester salts, alkyl ether sulfate ester salts (hereinafter also referred to as "AES"), or (alk) alkenyl ether sulfate ester salts; a carboxylic acid type such as a higher fatty acid having 8 to 22 carbon atoms or a salt thereof, an alkyl ether carboxylate, a polyoxyalkylene ether carboxylate, an alkyl (or (alk) enyl) amide ether carboxylate, an acylamino carboxylate, etc.; phosphoric acid ester types such as alkyl phosphate ester salts, polyoxyalkylene alkyl phenyl phosphate ester salts, and glycerin fatty acid ester monophosphoric acid ester salts. Examples of the salt in these anionic surfactants include alkali metal salts such as sodium salt and potassium salt; alkaline earth metal salts such as magnesium salts, and alkanolamine salts such as monoethanolamine salt and diethanolamine salt.

(method of treating textile product)

In the method for treating a textile product of the present invention, first, the textile product is immersed in the treatment liquid obtained by diluting the present composition with water, and then dehydrated.

Examples of the textile products include clothing, rags, sheets, curtains, pillow cases, and the like.

The material of the fiber product is not particularly limited, and examples thereof include natural fibers such as cotton, silk and wool, and chemical fibers such as polyester and polyamide.

The treatment liquid can be prepared by adding the present composition to water.

The amount of the present composition to be mixed with water is preferably 10 to 50mL per 30L of water, for example.

The proportion of the present composition to the total mass of the treatment liquid is preferably 0.01 to 0.3 mass%, more preferably 0.02 to 0.2 mass%.

If necessary, a known bleaching agent or softening agent may be added to the treatment liquid.

The content of the bleaching agent in the treatment liquid is not particularly limited. The bleaching agent is preferably added in an amount of, for example, 10 to 50mL per 30L of water. The proportion of the bleaching agent to the total mass of the treatment liquid is preferably 0.01 to 0.3 mass%, and more preferably 0.02 to 0.2 mass%. The content of the softening agent in the treatment liquid is not particularly limited. The ratio of the softening agent to the total mass of the treatment liquid is preferably 0.01 to 0.3 mass%, more preferably 0.02 to 0.3 mass%.

The fiber product can be treated with a known bleaching agent or softening agent before being treated with the treatment liquid (immersed and dehydrated in the treatment liquid). As a treatment method using a known bleaching agent or softening agent, there may be mentioned a method in which a bleaching agent or softening agent is dissolved in water in advance, a fiber product is immersed in the solution, and the fiber product taken out is washed in a washing machine or the like; a method of applying a bleaching agent or a softening agent to a textile, leaving the textile in place, and then washing the textile, and the like.

When the fiber product is immersed in the treatment liquid, the bath ratio of the mass of the treatment liquid to the mass of the fiber product (mass of the treatment liquid/mass of the fiber product) is preferably 5 to 50 times, and more preferably 15 to 25 times. If the bath ratio is within the above-mentioned preferable range, the deodorizing effect can be easily and stably imparted.

After the fiber product is impregnated in the treatment liquid, the treatment liquid may be left as it is or may be stirred. The composition can be used to replace detergent for washing fiber products in a washing machine. When the washing machine is used, the washing machine may be in a normal washing mode or in a mode in which the stirring force is weak, such as a soft washing mode. The present composition can be coated on a fibrous article and placed in place and then washed in a washing machine.

When the washing machine is used, dehydration can be continuously performed after washing.

The fiber product immersed in the treatment liquid may be dewatered and then rinsed with rinsing water, but from the viewpoint of the deodorizing effect, it is preferable to dry the fiber product without rinsing. When a washing machine is used, it is also preferable not to perform washing or rinsing after dehydration. By drying without rinsing, the component (B) is likely to remain in the textile product, and a more excellent deodorizing effect can be obtained.

The drying method may be a general drying method for a fiber product, and examples thereof include air drying, drying using a dryer (a clothes dryer, a bathroom dryer, etc.), and the like.

[ PREPARATION OF FIBER-PRODUCT TREATING AGENT COMPOSITION ]

Fiber product treating agent compositions of examples 1 to 15 and comparative examples 1 to 3 were prepared by adjusting the mixing amounts of the respective components as shown in tables 1 to 4 in the following manner.

The fiber product treating agent composition is obtained by mixing the component (A) and water uniformly, adding the component (B), stirring uniformly, adding an optional component, and stirring sufficiently.

In tables 1 to 4, the total amount of each component (mass%) is a ratio to the total mass of the fiber product treating agent composition, and indicates a value in terms of the pure component content unless otherwise specified. The "appropriate amount" means that the pH adjusting agent was mixed so that the pH of the fiber product treating agent composition at 25 ℃ became the values shown in tables 1 to 4. "balance" means that water is mixed so that the total mixing amount (mass%) of all the mixed components contained in the fiber product treating agent composition of each example is 100 mass%. That is, the amount of water is the remainder obtained by subtracting the total amount (in terms of purity) of the components to be mixed other than water from the total mass of the fiber product treating agent composition.

[ PREPARATION OF TEST CLOTH ]

Test cloths for odor evaluation were produced in the following order.

First, the test cloth was cleaned in the following procedure.

In a full-automatic electric washing machine (product name "JW-K33F" manufactured by hel corporation), about 30g of cotton knitted fabric (product name "CK43202" manufactured by riqing textile co., ltd., purchased from koku shop) and about 500g of cotton shirt (manufactured by b.v. d) were put, and the total mass of all the cloths to be washed was adjusted so as to be about 500g (bath ratio (washing water/total mass of cloths to be washed) in total).

Next, 10mL of a liquid detergent was added, and the washing operation of washing, rinsing, and dewatering was performed in this order according to the standard procedure. The washing time, rinsing, dewatering, and water volume (set to a low level, water volume of about 15L) were not adjusted at all, and were set using the standard program of the washing machine. This washing operation was repeated 5 times.

After the completion of the washing, the cotton knitted fabric taken out was dried in a constant temperature and humidity chamber having a humidity of 65% RH at 25 ℃. After drying, the test cloth was cut into a 5X 5cm square.

[ treatment based on fiber product treatment agent composition ]

The fiber product treatment agent composition was stirred at a ratio of 25mL to 30L of water for 30 seconds to prepare a treatment solution.

Next, a Terg-O-meter (manufactured by UNITED STATES TESTING) was prepared as a cleaning tester. The 5 test cloths and cotton shirts (manufactured by b.v.d) were put into a washing tester together with 900mL of the treatment liquid, and stirred at 120rpm and 15 ℃ for 10 minutes at a bath ratio of 20 times. Then, the test cloth and the cotton shirt were taken out, transferred to a dehydration tank of a two-tub washing machine (manufactured by TOSHIBA Co., ltd., product number: VH-30S (H)), dehydrated for 1 minute, and air-dried.

[ evaluation of deodorant Effect of body odor ]

On a test cloth treated with the fiber product treating agent composition, 200. Mu.L of a nonanoic acid solution diluted with 95 ℃ ethanol to 1000ppm was dropped as a body odor model. After 30 minutes, the odor intensity of the test cloths was evaluated organoleptically by a 6-person panel according to the 6-scale criteria described below. The lower the score of odor intensity, the weaker the odor, and the higher the odor-preventing effect (effect of suppressing body odor generation) indicating body odor.

Evaluation criteria for sensory evaluation "

And 5, dividing: the smell is strong.

And 4, dividing: the smell is strong.

And 3, dividing: can smell the smell easily.

And 2, dividing: weak odor if not present.

1 minute: the smell can be smelled only by exerting force.

0 minute: has no odor.

The average value of scores of odor intensity of 6 panelists was calculated (rounded to the second decimal place), and the odor-preventing effect was judged according to the following criteria. The evaluation was judged as good or good. The results are shown in tables 1 to 3.

Determination standard of deodorization effect "

Very good: the average odor intensity score was less than 2.5 points.

Good: the average value of the odor intensity score is more than 2.5 points and less than 3.0 points.

And (delta): the average value of the odor intensity score is 3.0 or more.

[ TABLE 1 ]

[ TABLE 2 ]

[ TABLE 3 ]

[ TABLE 4 ]

In examples 1 to 15, the excellent deodorizing effect can be imparted to the test cloth by a simple operation.

On the other hand, the deodorizing effect of comparative example 1 was poor. Since the component (a) is not contained, it is considered that the component (B) hardly permeates into the test cloth, and the component (B) hardly remains in the test cloth after the treatment.

In comparative example 2, since the component (B) was not contained, the deodorizing effect was poor.

The deodorizing effect of comparative example 3 was poor. It is considered that since the content of the component (a) is more than 10% by mass, the component (a) is selectively adsorbed on the test cloth, and the component (B) hardly remains on the test cloth after the treatment.
