Description

  The present invention relates to a method for suppressing the adhesion of pollen to a textile product.

  Japanese cedar and cypress pollen are allergens that cause allergic symptoms, and the specific symptoms are called hay fever. Since pollen is floating in the air, it cannot be removed by methods such as cleaning, and care should be taken not to be sucked into the body with a mask, etc., or these substances will not enter the living environment such as indoors. It has been done to defend by such means as to be careful. However, pollen often adheres to textile products such as clothing and is brought into the room, and methods such as wiping it off before entering the room are performed, but satisfactory effects cannot be obtained.

On the other hand, in Patent Document 1 and Patent Document 2, house dust is sprayed into a space by spraying a solution or dispersion containing a house dust treating agent that inactivates and / or removes allergens in house dust containing pollen. A spray-type house dust treating agent for removing water is described. Previously, the present applicant can remove pollen from clothing by performing an operation of removing the produced solid in Patent Document 3 after bringing an aqueous solution containing a compound that solidifies by volatilization into contact with a fiber product and drying it. Proposed method.

  However, the said patent document does not show about the agent and method which can suppress adhesion of pollen by processing to textiles beforehand.

  In view of such a situation, an object of the present invention is to provide an agent and a method for preventing pollen from adhering to a textile product.

  Surprisingly, the present inventors have found that the composition originally intended for removing pollen reduces the adhesion rate of pollen that adheres when going out by bringing the composition into contact with clothing beforehand. Invented the invention.

That is, the present invention suppresses pollen adhesion to a textile product by contacting the textile product with a pollen adhesion inhibitor for textile products containing the following components (a), (b) and (c) and drying the textile product. It provides a way to
Component (a): an organic compound that forms an azeotrope with water, and the azeotropic temperature with water at 101.25 hPa is less than 100 ° C. Component (b): Water (c) Component: Component (a) and (b Solid source material that dissolves in at least one of the components and produces a solid by evaporation of the liquid component in the solution

  The effect of this invention exists in suppressing the adhesion of the pollen to a textile product.

<(A) component>
Component (a) according to the present invention is an organic compound that forms an azeotrope with water and has an azeotropic temperature of less than 100 ° C. with water at 101.25 hPa (760 mmHg).

Compounds having an azeotropic temperature of less than 100 ° C., preferably 60-90 ° C., can be used from the compounds described in Tables 8 and 43 that form an azeotropic mixture with water. By using the component (a) in combination, drying of the fiber product treated with the inhibitor of the present invention is promoted, and generation of a solid derived from the component (c) is promoted. Preferred examples of the component (a) include ethanol, cyclohexane, 2-butanol, cyclohexanol, cyclohexanone, cyclohexane, toluene, 1-butanol, 2-butanol, 1-propanol, 2-propanol, 1-hexanol, hexane, 1 -Heptanol, 1-pentanol, 2-pentanol can be mentioned, and a C2-C7 alcohol compound is preferable.

  The surfactant of component (c1-2) is a solid state at 25 ° C., preferably 35 ° C., in a state where the moisture content [moisture in component (c1-2)] is 5% by mass or less. However, when the water content exceeds 5% by mass, ethanol or isopropanol is added, and azeotropic dehydration is performed under reduced pressure by an evaporator to reduce the water content to 5% by mass or less.

The moisture can be determined by the Karl Fischer method (JIS K 33625).

  The component (c2) is a combination of an inorganic cation and an inorganic anion, and an inorganic compound obtained by drying an aqueous solution containing these ions does not exhibit deliquescence and an inorganic anion. It is a combination. In the component (c2), the solid that precipitates upon drying the inhibitor of the present invention is produced using these inorganic cations and inorganic anions as the substance source, and may be precipitated as a hydrate. In addition, when various kinds of inorganic ions are mixed, the generated solid is not certain. However, in the present invention, any combination of inorganic ions for depositing solids may be used. The reason why the component (c2) is defined in this way is that the feature of the present invention is that a solid is formed after drying. For example, when there are a plurality of compounded compounds, an alkali as pH adjustment is further provided. This is because, when an agent / acid agent is added, or when an ion dissociative surfactant or organic acid salt is used in combination, the substance precipitated as a solid may be different from the substance originally mixed. However, the present invention does not deny that the inorganic solid of the electrolyte having no deliquescence [(c2 ′) component] is directly blended. In the present invention, “no deliquescence” refers to low hygroscopicity described later. In the component (c2), the inorganic cation is an alkali metal ion or an alkaline earth metal ion, and the inorganic anion is sulfate ion, carbonate ion (including hydrogen carbonate ion), phosphate ion (monohydrogen phosphate) 1 or more selected from fluorine ion, chlorine ion and bromine ion, and in particular, component (c2) is selected from potassium ion, sodium ion and magnesium ion. A combination of a cation (c2-c) and an anion (c2-a) selected from sulfate ion, carbonate ion (particularly hydrogen carbonate ion), fluorine ion and chlorine ion is preferred. However, a combination of only ions considered that the obtained solid becomes deliquescent is not preferable. Therefore, in the present invention, an electrolyte having no deliquescence [in the present invention, it is dissolved in water to generate an inorganic cation and an inorganic anion. ] Of the inorganic solid [(c2 ′) component]. Specifically, it is preferable to blend one or more inorganic salts selected from sodium sulfate, potassium sulfate, magnesium sulfate, sodium hydrogen carbonate, sodium fluoride, sodium chloride, and potassium chloride.

  More specifically preferable inorganic salts [(c2 ′) component] include sodium sulfate, magnesium sulfate, sodium carbonate, sodium hydrogen carbonate, sodium fluoride, sodium chloride, and potassium chloride, and particularly sodium sulfate, One or more selected from sodium hydrogen carbonate, sodium fluoride, and sodium chloride are preferred.

  The component (c) according to the present invention may be a mixture of the component (c1) and the component (c2). When the component (c1-2) is an ionic surfactant, the component (c1-3) is organic. In the case of an acid salt, the counter ion may be considered as (c2). Basically, any combination may be used as long as a solid precipitates from the inhibitor of the present invention containing the component (c).

  Of the components (c) according to the present invention, more preferred are the component (c1-1) and / or the component (c2), and most preferred are the components (c2-c) and (c2-a). ) A combination of ingredients. However, since the organic compound represented by (c1), particularly a surfactant such as (c1-2) is concerned that it remains on the target surface, the blending amount is preferably conservative.

  The component (c) of the present invention is different from the previously applied removal method, and it is desirable not to perform the removal step after spraying or coating the fiber product. Therefore, the solid source of the component (c) is desired to be a compound with little whitening.

  In addition, as described above, the action mechanism of the present invention suppresses electrostatic adhesion by solidly adhering to the pollen physically or changing the surface of the fiber product in a chargeable manner. It seems that this is the case, but the size of such an action mechanism is considered to vary depending on the type of component (c).

  (C1-1) component mix | blended with the pollen adhesion inhibitor of this invention is thought to exhibit an effect mainly by physical adhesion suppression. When the (a) component and (b) component are volatilized, the precipitate can take various forms such as a granular shape, a plate shape, and a needle shape. The component (c1-1) in the present invention is preferably granular and needle-shaped, particularly preferably needle-shaped, for the purpose of suppressing physical adhesion.

  Moreover, when a nonionic surfactant is used as the component (c1-2), in addition to physical adhesion inhibition, an electrostatic adhesion inhibition effect associated with holding moisture can be expected. When an ionic surfactant is used as the component (c1-2), in addition to these, an electrostatic adhesion suppression effect due to ionicity is also expected. Therefore, particularly when the component (c1-2) is used. Ionic surfactants are preferred.

  In the case of the component (c2), in the same way as the component (c1-2), in addition to the physical adhesion suppression, the retention of moisture and the electrostatic adhesion suppression effect due to ionicity can be expected.

  The retention of moisture is preferable from the viewpoint of an electrostatic adhesion suppressing effect, but a moisture amount that is high enough to bring about adhesion and adhesion is not preferable from the viewpoint of adhesion suppression.

<(D) component>
The inhibitor of the present invention can contain an organic compound other than the components (a) and (c) [hereinafter referred to as component (d)]. Examples of the component (d) include organic compounds other than the component (c1-1) (excluding the surfactant) and surfactants other than the component (c1-2). For example, fragrance ingredients, fluorescent brighteners, antibacterial / antifungal agents, bactericides, surfactants that are liquid at temperatures below 25 ° C., organic compounds that are liquid at 25 ° C. such as glycol solvents, and liquids at 25 ° C. Silicone oil and the like are also included. Since the blending of component (d) can affect the precipitation of solids from the inhibitor of the present invention, caution is required for its type and blending amount.

<Composition of pollen adhesion inhibitor>
In the pollen adhesion inhibitor of the present invention, the content of the component (a) promotes the purpose of uniformly dissolving the component (c) and optionally the component (d) in the pollen adhesion inhibitor and drying after spraying or application.

On the other hand, an excessive amount may cause whitening, change in the feel of the object, and stability of the pollen adhesion inhibitor, preferably 5% by mass or less, more preferably 3% by mass or less, and most preferably 0.01-2. % By mass.

  In particular, the component (a), the component (b) and the component (c) are in total in the pollen adhesion inhibitor, preferably 95 to 100% by mass, more preferably 97 to 100% by mass, and most preferably 98 to 98%. It is desirable to contain it so that it may become 100 mass%.

Also, care must be taken when setting the pH. In particular, since the equilibrium state of salts changes depending on the pH, the salt is a solid, but if it is a substance having a low solidification property with an acid or alkali, the solid may be difficult to precipitate depending on the pH. Therefore, in this invention, it is suitable to adjust pH at 20 degreeC of a pollen adhesion inhibitor to 3-12, Preferably it is 4-9. The pH adjuster preferably constitutes the component (c).

Specifically, when the solution-like pollen adhesion inhibitor containing the components (a) to (c) is brought into contact with a fiber product by spraying, dipping or the like, and the treated part is dried by evaporation of the liquid component The solid of component (c) is deposited on the fiber product surface. By leaving the deposited solid as it is, the effect of suppressing pollen adhesion is exhibited.

In addition, as textile products targeted by the present invention, clothes such as coats and jackets, laundry such as towels, bedding such as futons and sheets, bed pads, carpets, rugs, mats, rugs, curtains, cloth sofas, etc. Interior products.

In order to suppress pollen adhesion, a solution-form pollen adhesion inhibitor comprising the following ingredients was prepared with the composition shown in Table 1. The prepared pollen adhesion inhibitor was sprayed uniformly 4 times on a black polyester jersey cloth cut to 10 cm × 10 cm. The spray amount was 0.2 g / 100 cm ² . This was dried at 23 ° C. and 60% RH for 1 hour to obtain a test cloth. Next, four pieces of 2 cm × 2 cm test cloth pieces were cut out from the test cloth.

  1 mg of cedar pollen was accurately weighed into a 134 cc wide-mouth glass bottle (Daiichi Glass Co., Ltd., PS-11K), and 4 pieces of test cloth were placed here and shaken vigorously for 2 minutes.

After shaking, the test cloth pieces were gently taken out, and the center of one side of each test cloth piece was observed with a microscope at 5 mm × 5 mm, and the number of adhering cedar pollen was counted. The counts obtained from the four test cloth pieces were summed to obtain the pollen adhesion number (pieces / cm ² ). The experiment was performed three times for each pollen adhesion inhibitor, and the average value of the number of pollen adhesion was determined.

  The average value of pollen adhesion when spraying water instead of pollen adhesion inhibitor was 480, and the average value of pollen adhesion was 510 when similar operation was performed without spraying anything. Therefore, the following criteria were used for evaluation with reference to these values.

* Evaluation criteria The average number of pollen adherence is 0 to 149: The average number of adherent pollen is 150 to 299: The average number of good pollen is 300 to 449: The average number of adherent pollen is 450 More than: No effect
