Description

  The present invention relates to a functional fiber treatment agent, and more particularly to a functional fiber treatment agent that can be suitably used for the treatment of automobile floor mats and the like.

  Conventionally, an antiallergen composition containing at least one of alkylpolyaminoethylglycine or a salt thereof, alkyldimethylaminoacetic acid betaine, and an imidazolium compound as an amphoteric surfactant has been proposed (see, for example, Patent Document 1). ). According to Patent Document 1, the above-mentioned anti-allergen composition can be imparted with a function of reducing allergenicity to these fibers or fiber products by processing them into fibers or fiber products. Yes. Furthermore, the usage form of the anti-allergen composition is not particularly limited. For example, the anti-allergen composition can be used in a convenient form such as an aqueous solution, spray, aerosol, paste, powder, etc., but the liquid form is particularly easy to handle. That is explained.

Various studies have been conducted on imparting pollen adhesion preventing performance to the fiber surface (see, for example, Patent Documents 2 to 4).

  On the other hand, when focusing on the floor mats of automobiles as textile products, this floor mat often carries external contaminants attached to shoes. It creates an environment where bacteria and molds can easily propagate due to getting wet with water.

  Therefore, the present invention not only makes it difficult to stain fiber products such as floor mats, but also has an antibacterial property that can inactivate allergen substances brought in from the outside and kill or suppress the growth of bacteria and mold. An object of the present invention is to provide a textile product so that the installation space of the textile product, for example, a floor mat, can be cleaned of the interior space of the vehicle.

  The functional fiber treatment agent according to the present invention includes fine particle compounds selected from organic derivatives such as modified organosilicates and inorganic compounds, astringency, tannic acid, polyphenol compounds, catechin, chitin, chitosan, zirconium oxide compounds, and Ag fine particles. 1 type or multiple types chosen from the inorganic fine particle and the allergen inactivating agent which consists of amino acid derivatives, alcohol, cationic quaternary ammonium salt, and water as a solvent. In particular, among the astringent, tannic acid, polyphenol compound, catechin, chitin, chitosan, zirconium oxide compound, inorganic fine particles made of Ag fine particles, and allergen inactivator made of amino acid derivative, only inorganic fine particles made of Ag fine particles are selected. In addition, it is possible to select only the allergen inactivating agent made of an amino acid derivative, or to select the inorganic fine particles made of Ag fine particles and the allergen inactivating agent made of an amino acid derivative.

  In this functional fiber treatment agent, it is desirable that the fine particle compound has an effective content of 1 to 10 wt%, particularly 2 to 5 wt%.

  The allergen inactivating agent preferably has an effective content of 0.05 to 1 wt%, particularly 0.1 to 0.5 wt%.

  The alcohol content is desirably 10 to 50 wt%.

  The content of the cationic quaternary ammonium salt is desirably 0.05 to 1.0 wt%.

  The fine particle compound contained in the functional fiber treatment agent not only helps to reduce the space where pollen or dry dirt adheres to or enters between fibers by adhering to the fiber surface. Even if pollen or dry dirt adheres by creating a rough surface, it is useful for point adhesion. Therefore, the inclusion of the fine particle compound makes it difficult for pollen and dry dirt to adhere to the fiber, and when attached, they are likely to fall off. When the content (addition amount) of the fine particle compound is less than 1 wt%, the antifouling effect is not achieved, and when it exceeds 10 wt%, the fiber surface is excessively attached and the fiber surface becomes whitish or the texture of the fiber becomes hard. There is a fear.

  The functional fiber treatment agent may be one or more selected from astringency, tannic acid, polyphenolic compound, catechin, chitin, chitosan, zirconium oxide compound, inorganic fine particles composed of Ag fine particles, and allergen inactivating agent composed of amino acid derivatives. Among them, it is most preferable to select inorganic fine particles or amino acid derivatives among them. The reason for this is that other things such as astringents and tannic acid are often colored, so that when fibers are treated, the fibers may become colored.

  The above-mentioned allergen inactivators such as inorganic fine particles and amino acid derivatives inactivate allergens by contact with allergens (so-called allergens) such as cedar pollen allergens and mite allergens, which cause allergic diseases that have become a problem in recent years. It has a nature to activate. It has been found that when the content (addition amount) of the allergen inactivating agent is large, the antifouling performance deteriorates. If the amount added is less than 0.05 wt%, the allergen inactivation effect may be hardly exhibited. If it exceeds 1 wt%, the inactivation effect is sufficiently obtained, but the antifouling effect is deteriorated, and on the other hand, it is liable to become dirty.

  Addition of alcohol makes it easier to wet the fiber surface (especially synthetic fibers made of polyester and polypropylene that are difficult to get into water) and spreads the entire fiber when sprayed. Helps are given. Moreover, since it has a quick-drying property rather than water, the drying time in the drying process after processing to a fiber can also be shortened. Furthermore, the bactericidal effect by alcohol can also be expected. If the alcohol content is 10 wt% or less, the fiber surface is difficult to wet and drying also slows down. If it exceeds 50 wt%, the drying property is improved, but a problem of flammability appears, which is not preferable. If the alcohol content exceeds 60%, it will be treated as a dangerous substance in the law, which is not preferable.

  Cationic quaternary ammonium salts are generally widely used as bactericides and antibacterial agents, and in the present invention, they were initially blended to give antibacterial properties to the fiber surface. However, it has been found that as the research continues, it has an allergen inactivating effect, and the effect is improved by combining with the allergen inactivating agent described above. When the content (addition amount) of the cationic quaternary ammonium salt is less than 0.05 wt%, a sufficient antibacterial effect cannot be obtained. On the other hand, if it exceeds 1.0 wt%, the antibacterial effect is sufficiently obtained, but the antifouling effect is deteriorated, and on the contrary, it is liable to become dirty. In addition, it is preferable to combine a plurality of cationic quaternary ammonium salts, rather than using one kind of cationic quaternary ammonium salt, because the effect is likely to be obtained.

  If a large amount of an allergen inactivating agent or a cationic quaternary ammonium salt is added, the antifouling property tends to be lowered. If the antifouling property is maintained, the addition amount should be reduced as much as possible. Further, when an allergen inactivating agent or a cationic quaternary ammonium salt is combined, a sufficient effect can be obtained with a small amount of addition, so that the effect of adding each component is increased as compared with the case where each is added alone.

  As the water, ion-exchanged water can be suitably used. Water is used as a solvent.

  As described above, by treating the fiber with the functional fiber treating agent of the present invention, the following three effects can be simultaneously imparted to the fiber.

(1) Reduced adherence and adherence of dry dirt such as pollen and dust can be prevented, and dirt on the fiber surface can be removed simply by striking it, which may be difficult to remove depending on the type of dirt. Even in such a case, it can be easily removed with a vacuum cleaner or the like.
(2) A function of inactivating pollen and mite allergen can be added to the fiber surface.
(3) An antibacterial effect can be imparted to the fiber surface.

  The effects of the above (1), (2) and (3) can be similarly achieved by treating the automobile floor mat with the functional fiber treatment agent of the present invention. Therefore, not only can the floor mat be made difficult to get dirty, but it also inactivates allergen substances brought in from the outside, and the antibacterial property imparted to the floor mat promotes the suppression of bacterial and mold death or breeding, thereby increasing the space inside the vehicle. Can be cleaned.

  In addition, the functional fiber treatment agent of the present invention can be uniformly applied to a fiber product such as a floor mat using hand spray, aerosol, etc., and only needs to be dried at room temperature. There is also an advantage in handling that it is not necessary to apply heat.

Antifouling Evaluation Method 10.0 g of the sample solution prepared as described above was uniformly applied to a white carpet fabric (pile fabric made of 100% polypropylene) cut to 10 × 10 cm using a hand spray. What was dried at room temperature for 24 hours after coating was used as an antifouling property evaluation sample.
15 kinds of test dusts defined in JIS Z 8901 were used as pollutants.
The antifouling property evaluation sample is placed horizontally, and 15 kinds of test dust are uniformly sprinkled with 0.5 g from a position of about 10 to 15 cm above the test piece using a sieve. After sprinkling, gently tap the back of the fabric with your hand and shake off the dirt. Carpet fabric not treated with chemicals was used as a blank, and how much antifouling property was improved compared with the blank was evaluated.
Evaluation was performed as follows. The results are shown in Table 1.
◎: Slightly stained with little dirt ○: Although some dirt remains, there is a clear difference compared to the blank.
Δ: Dirt remains in a dark state, but the dirt is lighter than the blank.
X: As dirty as blank.

Method for evaluating allergen inactivation effect 5 g of the sample solution prepared as described above was uniformly applied to a white fabric (100% polyester fabric) cut to 5 × 5 cm using a hand spray. What was dried for 24 hours at room temperature after coating was used as a sample for evaluating the allergen inactivation effect.
An evaluation sample is put into a plastic bag with a fastener, and 2 ml of a cedar pollen allergen suspension (in which 90 parts by weight of ethyl alcohol and 10 parts by weight of purified water are dispersed in 1 part by weight of cedar pollen) is dropped. The liquid extracted after 1 hour was used as the evaluation liquid. The amount of cedar pollen allergen contained in the extracted evaluation liquid was measured by ELISA method, and the same test was performed only with the cedar pollen allergen suspension without putting an evaluation cloth, and this was used as a blank. The results are shown in Table 1.

The inactivation rate was calculated by the following formula.
Inactivation rate% = [(allergen amount of only cedar pollen allergen suspension−allergen amount of evaluation sample) / allergen amount of only cedar pollen allergen suspension] × 100
◎: Inactivation rate is 80% or more ○: Inactivation rate is 50 to 79%
Δ: Inactivation rate is 10 to 49%
X: Inactivation rate is 10% or less

Antibacterial Effect Evaluation Method 5 g of the sample solution prepared as described above was uniformly applied to a white fabric (100% polyester fabric) cut into 5 × 5 cm using a hand spray. An antibacterial effect evaluation sample was obtained by drying for 24 hours at room temperature while taking care not to contaminate the bacteria. Bacteria were inoculated after drying. The cloth inoculated with the bacteria was washed out with 20 mL of washing solution, and the number of bacteria was counted.
As the bacteria used, a mixture of Staphylococcus aureus, green bacterium and Escherichia coli was used. The results are shown in Table 1.
The number of inoculum is 9.6 × 10 7 / ml
A: Growing bacteria were not measured. O: Decreased by 10 @ 4 to 10 @ 5 or more than the number of ingested bacteria.
