[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mite-proof carpet.

[0002]

[Prior art]

 Currently, Western-style carpets are widely used regardless of Japanese-style rooms. Dust, dust, food, etc. tend to adhere to the inside of the carpet surface, and because proper temperature and humidity are maintained, there is a risk that pests such as mites often propagate. Ticks puncture the human body and cause itching and rash, and especially in the case of allergic people, the damage is a serious social problem.

For this reason, a method has been proposed in which a mite-proofing agent is kneaded into the pile yarn or attached to the surface as a mite-proofing carpet. Insecticide was added to the carpet.

[0004]

[Problems to be solved by the present application]

 However, in the method described above, the mites repellency was improved because the drug that affects the organism was in a position where it was easy to directly touch the skin, but there was concern about the safety. On the other hand, when insecticides were sprayed on pests such as mites, the pests died, but the carcasses remained behind the carpet pile, which could not be easily removed by cleaning, etc., and the carcasses of these insects caused allergies. For this reason, there was a demand for carpets that would prevent insects from dying rather than dying.

[0005]

[Means for Solving the Problems]

 The present application solves the above problems and has completed a mite-repellent carpet that is safe for pedestrians with a high mite-repellent rate.

According to the present invention, in a carpet having a pile cloth tufted with tufts on the primary backing and a backing, a resin layer containing dialkyl phthalate as a tick repellent is provided between the primary backing and the backing. The gist is a mite-repellent carpet characterized by being formed.

The invention will be described in detail below. FIG. 1 is a sectional view of a carpet of the present invention, 1 is a primary base cloth, 2 is a pile tufted on the primary base cloth, and 3 is a tufted fabric surface fiber layer. A lining material 4 is formed immediately below the primary base cloth of the surface fiber layer. As the backing material, a fiber secondary base cloth of an ordinary rolled carpet is suitable. In the present invention, a resin layer 5 is interposed between the primary base cloth 1 and the backing layer 4.

Conventional backing agents can be used in a wide range for the resin layer into which the pest repellent is mixed, and examples thereof include styrene-butadiene copolymer, urethane resin, vinyl chloride resin, vinyl acetate-ethylene copolymer. It is possible to exemplify those containing a latex system as an adhesive. When the repellent substance is mixed in the resin layer, the repellent substance may be mixed in an amount of about 0.5 to 15% by weight of the resin layer.

The mite repellent used in the present invention is phthalic acid diester disclosed as dimethyl phthalate or diethyl phthalate. Good results are also obtained by mixing dimethyl phthalate and diethyl phthalate. Thus, the mite-repellent carpet 6 of the present invention is obtained.

The obtained carpet is, for example, in the form of a roll, a mat, a rug, or a mat.

[0011]

[Function of the invention]

 Since the drug does not directly adhere to the pile, the drug does not come into contact with the skin and is safe, and the mite repellent is gradually released from between the piles, leaving no carcass of mites, resulting in no source of allergies and long-lasting effects.

[0012]

[Effect of device]

 Since there is a layer containing a pest repellent on the back of the primary backing of the pile surface agent, the action of the repellent reaches directly to the carpet surface side through the primary backing, and the dani most inhabits. It was possible to surely perform the control of the mites on the surface, which is a problem. In other words, even if dust, dust, plants, etc. adhered to the carpet, the mites hardly approached, the pests could be effectively extinguished, and there was very little opportunity for the mites to die and leave the carcass.

Further, according to the present invention, it becomes possible to prepare a mite-proof carpet regardless of the material of the carpet, and the contact of the mite with the carpet is significantly reduced.

The phthalic acid diester itself, which is a tick repellent of the present application, is safe and has little effect on the human body, and since the drug does not directly touch the skin, the drug has less effect on the human body and the double-bed Safety measures were obtained. In addition, the durability of the chemicals could be extended by mixing the mite repellant in the resin layer, as compared with the carpet in which pile yarns were treated with chemicals.

【Example】

Example 1 An acrylic spun yarn was tufted as a pile yarn on the primary backing fabric, and a raw machine of the standard shown in Table 1 was used, and SBR latex was used as a resin layer. 10 g of diethyl phthalate was added to 1000 g of latex, 1000 g was applied per 1 m ^{2 of the} primary base cloth, and a fiber backing material was attached and dried to obtain a tick-repellent carpet. A mite repellency test was carried out using this carpet sample, and the mite repellency rate after 7 days was measured.

[0016]

Example 2 A mite-repellent carpet similar to that of the example was obtained except that 20 g of diethyl phthalate was added to 1000 g of the latex.

[0017]

Example 3 A mite-repellent carpet similar to that in Example 1 was obtained except that the primary fabric was tufted with nylon BCF as a pile yarn and the tuft of the standard shown in Table 1 was used.

[0018]

Example 4 The same mites-repellent carpet as in Example 3 was obtained except that 20 g of diethyl phthalate was added to 1000 g / m ^{2 of} latex.

[0019]

Example 5 The same mites-repellent carpet as in Example 1 was obtained except that 30 g of dibutyl phthalate was added to 100 g / m ^{2 of} latex.

[0020]

Example 6 The same tick-repellent carpet as in Example 1 was obtained except that 10 g of diethyl phthalate and 20 g of dibutyl phthalate were added to 1000 g / m ^{2 of} latex.

[0021]

Comparative Examples 1 to 4 Same as Examples except that the repellent of Examples 1 to 4 was changed to a mixture of a known repellent isothiazolinone compound and a bamethsulin derivative (Sanitize RT-87-12, manufactured by Nippon Sands Co., Ltd.). Then, a repellent carpet was created.

The obtained Examples 1 to 4 and Comparative Examples 1 to 4 were tested by the following tick repellent test. Table 1 shows the results.

[0023]

[Tick repellent test] As shown in Fig. 1, seven glass petri dishes having an inner diameter of 3 cm were placed in a plastic container (with a capacity of 1.5 l) so as to be in contact with each other. The medium in which the mosquitoes were infested was put in one petri dish at the center. The survival number in the mite medium was 5000 individuals. A treated section and a control section were placed on each of the six glass petri dishes in contact with the surroundings. 0.01 g of a feed for attracting mites was added to the center of these samples. Adhesive sheets were laid around these petri dishes to prevent mites from mixing in with other petri dishes. In addition, in order to keep the humidity at 75% RH in the plastic container, place a container containing saturated saline, measure the repellent rate of the "number" of mites after 7 days by keeping it in the dark at 25 ° C. did.

[0024]

[Table 1]

[0025]

[Equation 1]

As shown in the above results, in the present application, the maximum repellent rate of about 98% was obtained in the examples, and most of the mites did not approach the carpet.

In Example 5, the mite repellency was 95%, and in Example 6, the mite repellency was 96%, both of which were high.

On the other hand, even with the conventional repellents, it was about 21% or less, many of the comparative examples were 0%, and the effect of repelling mites was low.
