Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber rug for pets, such as dogs and cats, which is suitably used for indoor use, for example, and more particularly, it has both an excellent deodorizing function and an excellent insect repellent function, and its effect. The present invention relates to a fiber rug for pets having excellent durability and a method for producing the same.

[0002]

2. Description of the Related Art When breeding pets indoors, especially indoors, the pets emit unpleasant odors, and the pets are infested with pests such as fleas, mites, mosquitoes and flies. The problem is that people's living and living environment deteriorates.

[0003] As a solution to the problem of bad odor caused by the breeding of pets, Japanese Patent Application Laid-Open No. 8-70724 adopts a structure in which roasted coffee extract residue is contained as a deodorant in animal sheets. In addition, Japanese Patent Application Laid-Open No. 62-74230 discloses a pet deodorant sheet comprising a deodorant fiber carrying metal porphyrin or a substituted derivative of metal porphyrin.

On the other hand, Japanese Patent Application Laid-Open No. H08-2980 discloses a solution to the problem of parasitism of pests such as fleas, mites, mosquitoes and flies.
Japanese Patent Application Publication No. 98889 discloses an animal excrement disposal material having an insect repellent function and comprising a granulated material containing a transpirable pyrethroid-based insect repellent such as empensulin. In addition, as a transpirant insecticide used for such a purpose, isobonyl thiocyanoacetic acid and the like are known.

[0005]

By the way, the former example is for solving the problem of bad smell caused by breeding pets, and does not basically have an insect repellent function.
On the other hand, the latter example is for solving the problem of parasitism of pests such as fleas, mites, mosquitoes and flies, and does not basically have a deodorizing function. That is, there has not been a fiber rug for pets having both the deodorizing function and the insect repelling function. As described above, there was no thing having both functions sufficiently, such as a coffee liquid extraction residue, a metal porphyrin, a deodorant such as a metal porphyrin derivative, and the transpirable pyrethroid-based insect repellent, isobonyl thiocyanoacetic acid, etc. When a transpirant insect repellent is simultaneously contained in a fiber rug for pets, for example, the transpired insect repellent is easily adsorbed to the deodorant, and therefore, the amount of the insect repellent that evaporates out of the fiber rug becomes extremely small. In addition to the insecticide effect being hardly exhibited as an insect repellent, on the other hand, the deodorant absorbs the evaporated insect repellent, so that the deodorant performance is reduced,
This is because the deodorant and the insect repellent interfere with each other to inhibit their functions. For this reason, at present, pet fiber rugs having both functions are hardly practically used.

The present invention has been made in view of such a technical background, and a deodorant and an insect repellent do not interfere with each other, and have both excellent deodorant performance and excellent insect repellent performance. In addition, an object of the present invention is to provide a fiber rug for pets excellent in the persistence of the effect and a method for producing the same.

[0007]

Means for Solving the Problems In order to achieve the above object, the present inventors have conducted intensive studies and selected diethyltoluamide as an insect repellent to be applied to a fiber rug for pets, while using an amine compound as a deodorant. By choosing, the deodorant and insect repellent do not interfere with each other,
The inventors have found that excellent deodorizing performance and excellent insect repelling performance can be ensured, and have completed the present invention.

That is, the pet fiber rug having both the deodorant function and the insect repellent function according to the present invention comprises a microcapsule body containing diethyltoluamide in a shell and an average particle size of 1%.
A deodorant comprising an amine compound having a particle size of 0 μm or less is fixed to a yarn constituting a fiber rug by a binder resin having a glass transition point of −30 ° C. or less.

Using diethyltoluamide as an insect repellent,
Since the amine compound is used as the deodorant, the two agents do not interfere with each other, and the original excellent deodorant performance and excellent insect repellent performance are exhibited. Also,
Since the average particle diameter of the amine compound is 10 μm or less, the texture can be made good without being rough when touching the fiber rug. Furthermore, since the glass transition point of the binder resin is −30 ° C. or less, the curing of the fiber rug due to the fixation of the binder resin is prevented, and not only an excellent texture is secured, but also the adhesion of the fiber rug to the constituent yarns. Also, it is possible to prevent the deodorant and the insect repellent from being detached from the fiber rug, and to achieve excellent deodorant performance and sustained durability of the insect repellent performance. In addition, since the insecticide diethyltoluamide is encapsulated in the microcapsule, good sustained release performance is exhibited.

[0010] Further, another pet fiber rug having both a deodorizing function and an insect repellent function of the present invention is a microcapsule body having diethyltoluamide encapsulated in a shell and having an average particle size of 1%.
An amine compound having a particle size of 0 μm or less and a deodorant comprising an inorganic substance are fixed to a yarn constituting a fiber rug by a binder resin having a glass transition point of −30 ° C. or less. .

Using diethyltoluamide as an insect repellent,
Since the amine compound and the inorganic substance are used as the deodorant, the two agents do not interfere with each other, and the original excellent deodorant performance and excellent insect repellent performance are exhibited. In addition, since an inorganic substance is used in combination as a deodorant, the removal efficiency of amine compounds whose removal efficiency is not sufficient, for example, odors such as ammonia and acetic acid can be sufficiently removed. That is, the amine compound and the inorganic substance are in a complementary form, and it becomes possible to efficiently remove most of various kinds of odors caused by the pet. The average particle size of the amine compound is 10
Since it is not more than μm, the texture can be made good without being rough when touching the fiber rug. Further, the glass transition point of the binder resin is -30.
° C or less, the curing of the fiber rug due to the fixation of the binder resin is prevented, and not only the excellent texture is secured, but also the deodorant has excellent fixability with the constituent yarns of the fiber rug,
Separation of the insect repellent from the fiber rug is prevented, and the deodorant performance and the insect repellent performance can be excellent in durability and durability. In addition, since the insecticide diethyltoluamide is encapsulated in the microcapsule, good sustained release performance is exhibited.

[0012] In any of the above inventions, the microcapsule may include, in its shell, one or more carriers selected from the group consisting of a plasticizer, a terpenoid, and a terpenoid derivative, in addition to the diethyltoluamide. It is preferable to include an agent. By the coexistence of such a carrier agent, the translocation of diethyltoluamide as an insect repellent is promoted, and a high insect repellent effect is exerted on the fiber rug. In addition, since the residual diethyltoluamide concentration in the microcapsule can be transferred to the induction transpiration until the residual diethyltoluamide concentration in the microcapsule becomes considerably low due to the coexistence of the carrier agent, its excellent insect repellent effect is maintained for a long time, Stable sustained release over a long period is ensured.

The mixing ratio of diethyltoluamide / carrier agent in the microcapsule is 5/1 to 5 / by weight.
It is preferably in the range of 5. If it is set in such a range, a more excellent insect repelling effect can be obtained at low cost.

It is preferable that the amine compound is one or more compounds selected from the group consisting of hydrazine derivatives having a solubility in water of 5 g / L or less at 25 ° C. By using a hydrazine derivative as the amine compound, the deodorizing performance is further improved. Further, since the solubility in water is 5 g / L or less at 25 ° C., even when the hydrazine derivative comes into contact with water due to washing such as washing, it is effective that the hydrazine derivative is dissolved in the water and flows out. Is prevented.

The content of diethyltoluamide is preferably 5 to 50 parts by weight, and the content of the deodorant is preferably 20 to 500 parts by weight based on 100 parts by weight of the binder resin. When it is set in such a range, it is possible to obtain more excellent deodorizing performance and more excellent insect repelling performance at low cost without lowering the function as a binder resin.

The amount of diethyltoluamide is 0.1 to 15 g / m
² and the deodorant is preferably applied at a rate of 5 to 30 g / m ² , in which case sufficient deodorant performance and sufficient insect repellent performance can be obtained without increasing cost. Secured.

It is preferable that a synergist is further contained as a component of the composition contained in the microcapsule body, whereby the transfer of diethyltoluamide to transpiration is further promoted.

As the above-mentioned synergist, it is preferable to use piperonyl butoxide since it is particularly excellent in the effect of promoting the transmigration of diethyltoluamide.

Further, according to the present invention, there is provided a method for producing a pet fiber rug having both a deodorizing function and an insect repellent function, comprising: a microcapsule body containing diethyltoluamide in a shell; an amine having an average particle size of 10 μm or less. A fiber rug is treated with a treating agent containing a functional composition comprising a deodorant composed of a compound and a binder resin having a glass transition point of -30 ° C or lower, and the functional composition is treated with a fiber rug. Characterized by being fixed to the yarn constituting

Since the treating agent contains a specific deodorant having a specific particle size, a specific insect repellent and a specific binder resin, it has excellent deodorizing performance and excellent insect repelling performance, and its effect. The fiber rug which is excellent in the persistence and the texture is provided. And this manufacturing method,
A rug already configured in the form of a fiber rug is subjected to a deodorizing process and an insect repellent process as a post-process, so that it can be applied to any type of fiber rug and is extremely excellent in versatility. Further, since the deodorizing process and the insect repelling process are not performed in separate steps but are performed simultaneously (processing with one liquid), the productivity is excellent. Such simultaneous processing is possible because the deodorant and the insect repellent do not interfere with each other as described above, and it is possible to simultaneously include both agents in one liquid. Furthermore, such a processing can be performed by simply applying a single treatment to the raw fiber rug by a spraying method, a dipping method, or the like. There is also an advantage that deodorization and insect repellent processing can be performed at a low cost.

The treatment of the fiber rug with the treating agent is preferably carried out by a spray method, whereby the productivity can be further improved.

[0022]

FIG. 1 is a schematic sectional view showing an embodiment of a pet fiber rug (1) having both a deodorizing function and an insect repelling function according to the present invention. The fiber rug according to this embodiment is a carpet, in which a backing layer (4) is laminated and integrated on the back surface of a carpet substrate (3) having a pile layer (2) on the surface, and a pile layer (2) And a deodorant and an insect repellent.

First, the fiber rug for pets of the present invention (1)
The deodorant adhered to the yarn constituting the following will be described. An amine compound is used as this deodorant. The amine compound is not particularly limited, but a hydrazine derivative is preferably used. Such an amine compound exhibits excellent deodorizing performance against odors emitted from pets. It is desirable that the solubility of such an amine compound in water is 5 g / L or less at 25 ° C. As long as the solubility in water is within this range, the amine compound is prevented from dissolving and flowing out of the water even if it is brought into contact with water by washing such as washing. . Therefore, the deodorizing performance can be maintained for a long time.

As the hydrazine derivative, for example,
Examples thereof include a reaction product of a hydrazine compound and a long-chain aliphatic compound, and a reaction product of a hydrazine compound and an aromatic compound.

Among them, one or two compounds selected from the group consisting of hydrazine and semicarbazide, and the compounds consisting of monocarboxylic acids, dicarboxylic acids, aromatic monocarboxylic acids and aromatic dicarboxylic acids having 8 to 16 carbon atoms. A reaction product with one or more selected compounds, one or two compounds selected from the group consisting of hydrazine and semicarbazide, and a group consisting of monoglycidyl derivatives and diglycidyl derivatives having 8 to 16 carbon atoms A reaction product with one or more compounds selected from the above is preferred. Use of such a hydrazine derivative can ensure more excellent deodorizing performance. Specific examples of the reaction product include sebacic acid dihydrazide, dodecane diacid dihydrazide, isophthalic acid dihydrazide, and the like, but are not particularly limited to these exemplified compounds.

In the present invention, an inorganic substance is preferably used in combination as the deodorant. By using this inorganic substance in combination, it is possible to exhibit the deodorizing performance against various kinds of odors caused by pets in combination with the action of the amine compound. As the inorganic substance,
For example, metal oxides having a surface activity such as activated alumina, titanium oxide, zinc oxide, and iron oxide may be mentioned, but are not particularly limited to these examples. Among them, it is preferable to use activated alumina and zinc oxide in combination as the inorganic substance, and in this case, it is preferable that the combination ratio of both is in the range of activated alumina / zinc oxide = 1/4 to 4/1. And particularly preferably, the range of activated alumina / zinc oxide = 1/3 to 3/1.

In the present invention, the average particle size of the amine compound and the inorganic substance used as the deodorant must be 10 μm or less. If it exceeds 10 μm, fiber rug (1)
Not only does the touch feel rough when touched, but also the texture of the rug decreases. Above all, the average particle size is 5μ
m, particularly preferably 3 μm or less.

Next, the fiber rug for pets of the present invention (1)
The insect repellent fixed to the yarn constituting the following will be described. Diethyltoluamide is used as this insect repellent. This diethyltoluamide, when used in combination with the above-mentioned specific deodorant, can secure the original excellent deodorant performance and excellent insect repellent performance because the two agents do not interfere with each other. is there.

In the present invention, the above-mentioned diethyltoluamide is encapsulated in the shell of the microcapsule. Since the insect repellent is thus encapsulated in the microcapsule, it is possible to exhibit good sustained release performance. The action of this diethyltoluamide is basically an insect repellent action and exerts an effect of keeping insects such as mites, mosquitoes, fleas, flies and the like, and therefore, unlike the action of so-called insecticides, Since it does not basically kill insects, it is possible to prevent carcasses of insects such as mites from remaining on the fiber rug. Accordingly, there is also an advantage that occurrence of allergic symptoms in humans due to dead bodies such as mites, which has been taken up as a major problem in recent years, can be effectively prevented. Of course, it is needless to say that a good living environment can be provided for pets.

Further, in addition to the above-mentioned diethyltoluamide, one or more carrier agents selected from the group consisting of plasticizers, terpenoids and terpenoid derivatives are encapsulated in the shell of the microcapsule body. Is preferred. By the coexistence of such a carrier agent, the translocation of diethyltoluamide, which is an insect repellent, can be promoted, and a high insect repellent effect can be exerted on the fiber rug. Therefore, even if the amount of encapsulated diethyltoluamide is small, a sufficient insect repellent effect can be obtained, so that the cost can be reduced.

The mechanism by which the co-presence of the above-mentioned carrier agent can promote the transfer of diethyltoluamide to transpiration is not clear. However, when these carrier agents become vapors and move out of the microcapsule body, In addition, it is presumed that diethyltoluamide in the microcapsule body is also actively induced to transmigrate to the outside.

Further, when adopting a configuration in which the above-mentioned carrier agent coexists in the microcapsule, there is an advantage that the excellent insect repellent effect is maintained for a long period of time, and a stable sustained release property can be secured for a long period of time. In the first place, diethyltoluamide is encapsulated in the microcapsule,
Although a good sustained-release property is exhibited, the concentration of the remaining diethyltoluamide in the microcapsule is lower in the system in which the carrier agent is present in addition to diethyltoluamide as compared with the system in which the carrier agent is not present. This is thought to be due to the fact that it becomes possible to transfer diethyltoluamide to the induction transpiration to a considerably low level. In other words, in a system in which a carrier agent is not coexisted, the transpilation transition is slow in a state where the concentration of residual diethyltoluamide in the microcapsule is relatively high, and the effect is difficult to be exhibited, whereas a system in which a carrier agent is coexisted. It is presumed that this is because diethyltoluamide can be transferred by induction until the residual diethyltoluamide concentration in the microcapsule becomes a considerably low value. Therefore, with a less insect repellent content than before, a high insect repellent effect is exhibited in the fiber rug, and the excellent insect repellent effect is maintained for a long period of time. in this way,
It can be a drug with a high drug efficacy (the ratio of the total amount of the added insect repellent that could be involved in drug efficacy by evaporation), and thus can exert the above-mentioned excellent effects at low cost. A fiber rug for pets can be provided.

As the plasticizer, known plasticizers used as plasticizers for synthetic resins can be used. For example, di-n-butyl adipate, di-n-dodecyl adipate, acetobutyl citrate, dodecane-2-acid Dimethyl, di-2-ethylhexyl maleate, dibutyl sebacate and the like. Of these, di-n-butyl adipate, di-n-dodecyl adipate, acetobutyl citrate, and dimethyl dodecane-2-ate are preferably used because the transfer of diethyltoluamide to transpiration can be further promoted.

The terpenoids and terpenoid derivatives are not particularly restricted but include, for example, limonene, benzyl benzoate, benzyl alcohol, cinnamate alcohol, benzyl salicylate and the like. Among them,
It is preferable to use limonene, benzyl benzoate, benzyl alcohol, or benzyl salicylate, since the transfer of diethyltoluamide to transpiration can be further promoted.

In the case where the above-mentioned carrier agent is included in the shell of the microcapsule in addition to diethyltoluamide, the mixing ratio in the microcapsule is as follows: diethyltoluamide / carrier agent = 5 / It is preferred to be in the range of 1-5 / 5 (weight ratio). If the mixing ratio of the carrier agent is smaller than the lower limit of the above range, the effect of promoting the transfer of diethyltoluamide by evaporation cannot be obtained so much, which is not preferable. On the other hand, if the mixing ratio of diethyltoluamide is smaller than the lower limit of the above range, the amount other than the medicinal component is increased more than necessary, which undesirably increases the cost. Above all, it is more preferable that diethyltoluamide / carrier agent = 5/2 to 5/3 (weight ratio).

Further, it is preferable that a synergist is contained in the shell of the microcapsule in addition to diethyltoluamide and a carrier. Here, the synergist is
It is a chemical substance which itself is not effective, but is known to increase its insect repellent performance by coexisting with an insect repellent, and by allowing such a synergist to coexist with the carrier agent. There is an advantage that the evaporation transfer of diethyltoluamide can be further promoted. The synergist is not particularly limited, and examples thereof include piperonyl butoxide, isobonyl thiocyanoacetate, and the like. Among them, piperonyl butoxide is particularly preferred. The mixing ratio of the synergist is preferably in the range of 100 to 300 parts by weight with respect to 100 parts by weight of the carrier agent.

A composition obtained by dissolving or dispersing the above-mentioned compound (diethyltoluamide, if necessary, a carrier agent, a synergist, etc.) in water is defined as an inclusion in a microcapsule. The composition may contain a surfactant such as a nonionic surfactant and various additives such as a thickener.

The microcapsule is obtained by encapsulating the above-mentioned composition in a shell. The material of the shell is not particularly limited, but a polymer material such as a synthetic resin is usually used. Examples of the synthetic resin constituting the shell include urethane resin, melamine resin, polyamide resin, urea resin and the like. Among them, urethane resins are preferred.

The microcapsule body can be manufactured, for example, as follows. That is, for example, a composition obtained by sufficiently mixing the composition (alkali-resistant insect repellent, carrier agent, synergist, surfactant if necessary) and a divalent or higher aliphatic isocyanate, It is added to the thickener solution, emulsified using a homogenizer, and after cooling this emulsion, an aqueous solution of a compound having two or more hydroxyl groups is added dropwise to the emulsion, followed by heating and stirring. can do. As a specific example, 25 parts by weight of an alkali-resistant insect repellent, 5 parts by weight of a carrier agent, 8 parts by weight of a synergist, 3 parts by weight of a nonionic surfactant, and 7 parts by weight of hexamethylene diisocyanate are sufficiently mixed. Was added to 30 parts by weight of a 4% thickener (carboxymethylcellulose) solution, and emulsified using a homogenizer. The emulsion was cooled to 25 to 30 ° C., and ethylene glycol was added to the emulsion. 22 parts by weight of a 2% aqueous solution was dropped and stirred for 1 hour, and then stirred at 60 ° C. for 3 hours to form a microcapsule in which an alkali-resistant insect repellent, a carrier agent, and a synergist were encapsulated in a urethane resin shell. Can be produced.

The particle size of the microcapsule is 1 to 1
It is preferable that the thickness be in the range of 00 μm. If it is less than 1 μm, it is not preferable because the insect repellent amount becomes small and a sufficient insect repellent effect is hardly obtained, and if it exceeds 100 μm, the dispersion of the insect repellent in the insect repellent composition tends to be non-uniform, so that it is preferable. Absent. Among them, the particle diameter of the microcapsule is more preferably in the range of 2 to 10 μm. The shell preferably has a thickness of 0.05 to 0.5 times the particle diameter of the microcapsule.

On the other hand, as the binder resin, it is necessary to use a resin having a glass transition point (Tg) of -30 ° C. or lower. If the temperature is higher than -30 ° C, the texture of the resulting fiber rug significantly decreases. Among them, it is preferable to use a resin having a glass transition point (Tg) of −35 ° C. or less.

As the binder resin, any resin can be used as long as its glass transition point (Tg) is -30 ° C. or lower. For example, self-crosslinking acrylic resin, methacrylic resin, urethane resin, silicone resin , Glyoxal resin, vinyl acetate resin, vinylidene chloride resin,
Butadiene resin, melamine resin, epoxy resin, acrylic-silicon copolymer resin, ethylene-vinyl acetate copolymer resin, isobutylene maleic anhydride copolymer resin,
Ethylene-styrene-acrylate-methacrylate copolymer resin and the like can be mentioned. Two or more of these resins may be mixed to form a binder resin.

In the present invention, the weight ratio of diethyltoluamide, the deodorant, and the binder resin to be fixed to the yarn constituting the fiber rug for pets is 100 parts by weight of the binder resin.
The content of diethyltoluamide is 5 to 50 parts by weight.
It is preferable to set the content of the deodorant to 20 to 500 parts by weight based on 100 parts by weight of the binder resin. When the content of diethyltoluamide is larger than the above range, the sticking property to the rug constituting yarn is reduced, and the diethyltoluamide and the deodorant are easily detached from the fiber rug. In addition to lowering the
It is not preferable because of high cost. The same applies when the content of the deodorant is larger than the above range. On the other hand, if the content of diethyltoluamide is smaller than the above range, the insect repellent performance tends to decrease, which is not preferable. On the other hand, if the content of the deodorant is smaller than the above range, the deodorant performance tends to decrease, which is not preferable. Above all, the content of diethyltoluamide is set to 10 to 25 parts by weight with respect to 100 parts by weight of the binder resin, and
More preferably, the content of the deodorant is set to 150 to 350 parts by weight with respect to parts by weight.

In the fiber rug for pets of the present invention, the amount of the deodorant applied is preferably 5 to 30 g / m ² (dry weight). If it is less than 5 g / m ^2, it is not preferable because sufficient deodorizing performance cannot be obtained. On the other hand, if it exceeds 30 g / m ² , no further improvement in deodorizing performance can be expected, and the cost is undesirably increased.

The amount of diethyltoluamide applied is as follows:
It is preferably 0.1 to 15 g / m ² (dry weight). If the amount is less than 0.1 g / m ^2, it is not preferable because sufficient insect repelling performance cannot be obtained. On the other hand, if the amount exceeds 15 g / m ² , further improvement in insect repelling performance cannot be expected, and the cost is undesirably increased.

On the other hand, in the carpet according to the above-described embodiment, the carpet substrate (3) is not particularly limited, and any material can be used. For example,
Needles of various fibers and yarns in addition to synthetic fibers such as polyester fibers, nylon fibers, polypropylene fibers, and acrylic fibers, or yarns made of fibers such as natural fibers such as hemp, cotton, and wool. Or a non-woven fabric bonded chemically with an adhesive or the like.

The pile material of the pile layer (2) is not particularly limited, and those made of fibers such as polyester fiber, nylon fiber, polypropylene fiber, acrylic fiber and rayon fiber can be suitably used. Those made of natural fibers such as hemp, cotton, wool and the like can be used. Further, the means for forming the pile layer is not particularly limited.For example, a means for forming a pile layer by weaving such as a warp pile weave or a weft pile weave, such as a moquette, or a method of planting pile yarn with a tufting machine or the like. Means for forming a pile layer, means for forming a pile layer by a knitting machine, means for forming a pile layer by bonding pile yarns using an adhesive, and the like can be exemplified. The pile form is not particularly limited, and may be any form such as a cut pile and a loop pile.

The material of the backing layer (4) is not particularly limited, and examples thereof include a resin composition, a rubber composition, a jute, a woven polypropylene fabric, and a needle punch base fabric. And rubber compositions are used. As a resin component of this resin composition, acrylic,
Resins such as urethane, polyvinyl chloride, polyethylene, polypropylene, and ethylene-vinyl acetate copolymer (EVA) can be given. Further, as rubber components of the rubber composition, SBR (styrene-butadiene rubber), M
BR (methyl methacrylate-butadiene rubber), NB
R (acrylonitrile-butadiene rubber) or natural rubber.

In the present invention, the type of the fiber rug (1) is not particularly limited, and may be constituted as a mat or a tile carpet, for example, in addition to the above-mentioned ordinary carpet and the like. For example, it can be configured as a moquette or the like for upholstering. The material of the yarn constituting the fiber rug for pets (1) is not particularly limited as described above, and examples thereof include polyester fiber, nylon fiber, polypropylene fiber, acrylic fiber, rayon fiber and the like. And natural fibers such as cotton and wool.

Fiber rug for pet according to the present invention (1)
Can be manufactured, for example, as follows.

First, a treatment agent comprising an aqueous dispersion in which a functional composition comprising the deodorant, the microcapsules, and the binder resin is dispersed in water is prepared. At this time, it is preferable that the deodorant and the microcapsule are dispersed as uniformly as possible, and it is more preferable that the binder resin is formed into an emulsion state with water. In addition, as a dispersion medium, alcohol and the like can be used in addition to water, but water is preferable.

In the preparation, the deodorant is first dispersed in water, and then the microcapsules and the binder resin are further dispersed therein.
It is preferable from the viewpoint of more uniformly dispersing the three components of the microcapsule body and the binder resin.

The processing agent may contain various additives such as a dispersant and a thickener for improving the properties of the processing agent. Further, for the purpose of improving various properties of the fiber rug, additives such as an antibacterial agent, a hydrophilizing agent, and a flame retardant can be appropriately compounded as long as the effects of the present invention are not impaired.

The fiber rug is treated with the treating agent thus obtained, and the functional composition is applied to the yarns constituting the fiber rug and fixed. The application means is not particularly limited, and examples thereof include a spray method, a foaming method, an immersion method, a coating method, and a padding method. Among them, the spray method is preferable from the viewpoint of workability at the time of application, production efficiency, processing cost, and the like.

After the functional composition is applied in this manner, the fiber rug is dried. The drying means is not particularly limited. The drying may be performed by air drying or heat treatment. In consideration of the efficiency of the treatment, it is desirable to dry by a heat treatment.

Further, the temperature of the heat treatment is 100 to 1
Preferably, the temperature is 80 ° C. By the heat treatment at this temperature, the sticking property of the functional composition to the fiber rug can be further increased, and the sustained durability of the deodorant performance and the insect repellent performance can be further improved.

According to the manufacturing method as described above, deodorization and insect repellent processing are performed as a post-process on a rug already configured in the form of a fiber rug, so that the invention can be applied to fiber rugs of any form. It is very versatile.
Further, since the deodorizing process and the insect repelling process are not performed in separate steps but are performed simultaneously (processing with one liquid), the productivity is excellent. Such simultaneous processing is possible because, as described above, the deodorant and the insect repellent used in the present invention do not interfere with each other, and therefore these two agents can be simultaneously contained in one liquid. Because it became. Furthermore, such a processing can be performed by simply applying a single treatment to the raw fiber rug by a spray method, a dipping method, or the like, so that productivity can be further improved and low cost can be achieved. There is also an advantage that deodorization and insect repellent processing can be performed.

Of course, for example, the fiber rug is treated with a treating agent in which the deodorant and the binder resin are dispersed in water, and then the fiber is treated with a treating agent in which the microcapsule body and the binder resin are dispersed in water. Although a two-step manufacturing method in which rugs are treated may be used, it is not preferable because productivity is significantly reduced.

The fiber rug for pets (1) according to the present invention is not particularly limited to those manufactured by the above-mentioned manufacturing method. A fiber rug may be constituted by using an original yarn fixed on the surface with a binder resin having a glass transition point of −30 ° C. or lower as a constituent yarn of the fiber rug.

Further, the site where the functional composition is applied to the pet fiber rug is not particularly limited, and a configuration in which the functional composition is applied to all portions of the fiber rug may be employed. It is also possible to adopt a configuration of giving to a part.
Further, a configuration provided on the front side of the fiber rug may be employed, or a configuration provided on the back side of the fiber rug may be employed. However, it is desirable to adopt a configuration in which the fiber rug is provided on the surface side (for example, a pile layer) from the viewpoint of exhibiting the deodorizing and insect repelling effects more greatly.

[Table 6]

As is clear from the table, the fiber rugs for pets of Examples 1 to 9 of the present invention can not only obtain a high insect repellent rate, but also have excellent durability against the insect repellent effect.
The deodorant performance was excellent, and the deodorant performance had sufficient sustained durability. In addition, these pet fiber rugs had an excellent texture.

On the other hand, in Comparative Examples 1 and 2, the insect repellency was low and the durability was poor, and the deodorizing performance and the durability were not sufficient.

[0096]

As described above, the pet fiber rug having both the deodorant function and the insect repellent function of the present invention uses diethyltoluamide as an insect repellent, and uses an amine compound or an amine compound and an inorganic substance as a deodorant. Because we use both,
The deodorant and the insect repellent do not interfere with each other, and can exhibit their original excellent deodorant performance and insect repellent performance. In addition, since the particle diameter of the amine compound is 10 μm or less, the feeling is not rough and the texture is good. Further, the glass transition point of the binder resin is -3.
Since the temperature is 0 ° C. or less, an excellent texture can be secured. In addition, since the glass transition point of the resin is -30 ° C or lower, the deodorant and the insect repellent can be effectively prevented from detaching from the fiber rug, since the adhesiveness to the fiber rug constituting yarn is excellent, and the deodorant performance and It also has excellent durability against insect repellency.

When an inorganic substance is used in combination as a deodorant, it is possible to sufficiently deodorize, for example, odors such as ammonia which do not have sufficient removal efficiency with amine compounds.
That is, the amine compound and the inorganic substance are complementary to each other, so that most kinds of odors caused by the pet can be efficiently deodorized.

In the case where the microcapsule contains one or more kinds of carrier agents selected from the group consisting of plasticizers, terpenoids and terpenoid derivatives in addition to diethyltoluamide in the shell, Can promote the transpilation of diethyltoluamide, which is an insect repellent, due to the coexistence of a carrier agent, and thus can exert a higher insect repellent effect on fiber rugs. Moreover, the excellent insect repellent effect can be exhibited for a longer period of time.

The mixing ratio of diethyltoluamide / carrier agent in the microcapsule was 5/1 to 5 /
When it is in the range of 5, more excellent insect repellent effect can be obtained at low cost.

The amine compound has a solubility in water of 25.
In the case of one or two or more compounds selected from the group consisting of hydrazine derivatives at 5 ° C. or less at 5 ° C., not only can a more excellent deodorant performance be ensured,
Sufficient water resistance to water for washing or the like can be imparted, and excellent deodorizing performance can be ensured for a longer period.

When the content of diethyltoluamide is 5 to 50 parts by weight and the content of the deodorant is 20 to 500 parts by weight with respect to 100 parts by weight of the binder resin, the function as the binder resin is obtained. It is possible to obtain more excellent deodorizing performance and more excellent insect repellent performance while sufficiently securing (fixation property and the like).

0.1 to 15 g / m of diethyltoluamide
² and the deodorant is 5 to 30 g / m
^{When applied at} a ratio of ² , excellent deodorant performance and excellent insect repellent performance can be secured without increasing costs.

When a synergist is contained as a component of the composition contained in the microcapsule, the transfer of diethyltoluamide to transpiration can be further promoted, so that a more excellent insect repellent effect can be obtained. .

When the synergist is piperonyl butoxide, the transfer of diethyltoluamide to transpiration can be further promoted.

Further, according to the method for producing a pet fiber rug of the present invention, a specific deodorant having a specific particle size is contained in the treating agent.
Since it contains a specific insect repellent and a specific binder resin, it is possible to provide a fiber rug excellent in texture, excellent in deodorant performance and insect repellency, and excellent in durability for the effect. Moreover, since the rug is already formed and subjected to deodorization and insect repellent processing as a post-process, it is extremely versatile. Furthermore, since the deodorizing process and the insect repelling process can be performed simultaneously with one liquid, there is an advantage that the productivity is excellent and the cost can be reduced.

When an inorganic substance is used together with an amine compound as a deodorant, a fiber rug capable of efficiently deodorizing most of various kinds of odors caused by pets can be provided.

When the treatment of the fiber rug with the treating agent is performed by the spray method, the productivity can be further improved.
