Description

[Technical field]

[0001] The present invention relates to a mite trapping product for trapping mites lurking indoors, and a method for trapping mites. [Background technology]

[0002] In recent years, airtight living environments have made it easier for mites to breed, which has become a problem. Since mites are considered to be the main cause of atopic dermatitis, asthma, allergies, etc., the general public is hoping for a means and method to eradicate mites reliably and safely.

[0003] There are methods to exterminate mites using chemicals such as insecticides and repellents. However, these methods do not actively reduce the number of mites, and have the problem of leaving behind dead mite bodies. In addition, people who are sensitive to chemicals are concerned about the effects of chemicals, so there is a demand for means and methods to easily exterminate mites without using chemicals as much as possible.

[0004] Therefore, to exterminate mites, a type of product (mite sheet) that attracts and captures mites rather than killing or repelling them has been developed (see, for example, Patent Document 1). The mite sheet of Patent Document 1 has an attractant placed on an adhesive, which is sandwiched between breathable layers from above and below. According to Patent Document 1, mites are attracted to the attractant on the inside of the two breathable layers, and then are fixed to the adhesive, thereby being captured by the mite sheet. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2009-89610 A Summary of the Invention [Problem to be solved by the invention]

[0006] For the above-mentioned products that attract and capture mites, it is extremely important that they have a good effect of attracting mites. If the product is not effective in attracting mites, it will not be able to reliably guide the mites to the adhesive and capture them even if they approach the product. On the other hand, if the product relies solely on the attractant to attract mites, the product will be significantly less effective when the attractant loses its effectiveness due to long-term use.

[0007] In this regard, in the mite sheet of Patent Document 1, in order to capture mites with the adhesive, the mites must pass through the breathable layer. Then, depending on the material and characteristics of the breathable layer, there is a risk that the attractant's effect of attracting mites may be weakened. In addition, since the mite sheet of Patent Document 1 requires an attractant, if the attractant's effect is lost, there is a possibility that the mite sheet will not even be able to attract mites to the vicinity of the mite sheet.

[0008] As such, it cannot be said that conventional products that attract and capture mites, including the mite sheet of Patent Document 1, were necessarily effective in attracting mites, and there was still room for improvement.

[0009] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a mite capturing product and a mite capturing method that have excellent effect in attracting mites and can reliably and safely capture and exterminate the attracted mites. [Means for solving the problem]

[0010] The characteristic configuration of the mite trapping product according to the present invention for solving the above problems is as follows: A fiber structure having fluff; The adhesive that fixes mites and The reason is that it is equipped with the following features.

[0011] Mites often hide in textile products such as clothing, tatami mats, and carpets, but the present inventors have found that mites are specifically attracted to textile structures with fluff, and have succeeded in developing a new mite capture product that utilizes this specific phenomenon. That is, according to the mite capture product of this configuration, first, mites are attracted to a textile structure with fluff, and the attracted mites are made to stay in the textile structure, or the mites are made to wander around the textile structure, and then the mites are fixed to the adhesive body, so that a mite capture product with excellent capture performance can be provided. Then, the mites captured by the mite capture product can be exterminated by simply disposing of the mite capture product as it is. In addition, since the mite capture product of this configuration does not use chemicals such as insecticides or repellents, even people who are sensitive to chemicals can use it with peace of mind.

[0012] In the mite trapping product according to the present invention, The fibers constituting the fiber structure preferably have an elongation of 10% or less.

[0013] According to the mite capture product of this configuration, since the elongation of the fibers constituting the fiber structure is 10% or less, more mites are attracted to the fiber structure, thereby providing a mite capture product with superior capture performance.

[0014] In the mite trapping product according to the present invention, The fiber structure is preferably a woven or knitted fabric having a thread density of 10 to 100 threads / 10 cm.

[0015] According to the mite capture product of this configuration, by using a woven or knitted fabric with a thread density of 10 to 100 threads / 10 cm as the fiber structure, more mites are attracted to the fiber structure, and a mite capture product with superior capture performance can be provided.

[0016] In the mite trapping product according to the present invention, The fiber structure preferably contains at least bast fibers and / or seed hair fibers.

[0017] According to the mite capture product of this configuration, since the fiber structure contains at least bast fibers and / or seed hair fibers, more mites are attracted to the fiber structure, thereby providing a mite capture product with superior capture performance.

[0018] In the mite trapping product according to the present invention, It is preferable that an attractant is provided between the fiber structure and the adhesive body.

[0019] According to the mite capture product of this configuration, by providing an attractant between the fiber structure and the adhesive body, a synergistic effect between the fiber structure, which has an attractive effect on mites, and the attractant can be achieved, providing a mite capture product with even better capture performance.

[0020] In the mite trapping product according to the present invention, It is preferable that at least a part of the fiber structure is covered with a fluff-free breathable sheet.

[0021] According to the mite trapping product of this configuration, at least a part of the fiber structure is covered with a breathable sheet having no fluff, which makes it easy for mites to penetrate into the product. In addition, since the fluff of the fiber structure is not exposed on the outer surface of the product, it is easy to insert into small gaps and is easy to dispose of after use, making it a user-friendly mite trapping product.

[0022] In the mite trapping product according to the present invention, The thickness of the fiber structure is a (mm), and the basis weight of the fiber structure is b (g / m 2 ), the following equation (1): 0.1 ≦ (a 2 / b) × 100 ≦ 1.0 (1) It is preferable that the following conditions are satisfied.

[0023] According to the mite-trapping product of this configuration, by satisfying the above formula (1), a larger number of mites are attracted to the fiber structure, and a mite-trapping product with superior trapping performance can be provided.

[0024] In the mite trapping product according to the present invention, It is preferred that it is free of insecticides and / or repellents.

[0025] Since the mite capture product of this configuration does not contain any insecticides and / or repellents, the mite attracting effect is not significantly weakened, and even people who are sensitive to chemicals can use it safely.

[0026] The characteristic configuration of the mite trapping product according to the present invention for solving the above problems is as follows: The purpose is to attract and capture mites that have invaded an area within a radius of 1m.

[0027] According to the mite trapping product of the present configuration, it is possible to provide an excellent mite trapping product that can reliably trap mites that approach the product.

[0028] In the mite trapping product according to the present invention, It is preferable to attract and capture the mites within 24 hours.

[0029] According to the mite trapping product of this configuration, it is possible to provide an excellent mite trapping product that can trap mites approaching the product in a short period of time.

[0030] The characteristic configuration of the method for capturing mites according to the present invention for solving the above problems is as follows: Any one of the above-mentioned mite trapping products is placed in or near a place where mites live to attract and trap the mites.

[0031] According to the mite capturing method of this configuration, because the mite capturing product of the present invention is used, it is possible to provide a mite capturing method that has excellent effect in attracting mites and can reliably and safely capture and exterminate the attracted mites.

[0033] Hereinafter, the embodiment of the mite trapping product and the mite trapping method of the present invention will be described in detail with reference to the drawings. Note that in each drawing, the components of the mite trapping product are not strictly reproduced in terms of their actual shape, size, positional relationship, thickness of each layer, scale, etc., but are appropriately exaggerated or simplified for ease of explanation. Furthermore, the present invention is not intended to be limited to the embodiments described below or the configurations shown in the drawings.

[0034] First Embodiment [Tick-trapping products] Fig. 1 is a schematic cross-sectional view of a mite-trapping product 100 according to a first embodiment of the present invention. The mite-trapping product 100 is formed by laminating a fiber structure 10 and an adhesive body 20. Fig. 1 illustrates an example in which two fiber structures 10 are laminated on both sides of the adhesive body 20, but the mite-trapping product 100 may have a structure in which one fiber structure 10 is laminated only on one side of the adhesive body 20. Fig. 1 illustrates an example in which only one layer of the fiber structure 10 is laminated on one side of the adhesive body 20, but the mite-trapping product 100 may have a structure in which two or more layers of the fiber structure 10 are laminated on one side of the adhesive body 20.

[0035] The mite trapping product 100 is a product used to attract and trap mites by installing it in or near a place where mites live. In the mite trapping product 100, the fiber structure 10 attracts mites by itself and retains them inside, thereby fixing the mites. The mite trapping product 100 further includes the fiber structure 10 laminated on the adhesive body 20, so that the mites attracted to the fiber structure 10 can be brought into contact with the adhesive body 20 and fixed to its surface to be trapped. The mite trapping product 100 is preferably in a sheet form so that it can be used by laying it under a futon, tatami mat, rug, carpet, etc., where mites live, or by inserting it into the gap between the seat and backrest of a sofa, etc. The shape of the mite trapping product 100 in a plan view is not particularly limited, but it can be a square, polygonal, circular, elliptical, etc., and these shapes are preferable because they are easy to handle.

[0036] In this way, the mite capture product 100 can be configured to be free of insecticides and / or repellents because it can attract mites with the fiber structure 10. Therefore, the effect of attracting mites is not significantly weakened. Also, because it does not contain insecticides and / or repellents, it can be used safely even by people who are sensitive to chemicals.

[0037] The textile structure 10 is a woven or knitted fabric having fluff. The weave of the woven or knitted fabric is not particularly limited, but is preferably a plain weave. The mite trapping product 100 effectively attracts mites to the textile structure 10 by utilizing the phenomenon that mites are specifically attracted to the textile structure 10 having fluff, and causes the attracted mites to remain within the textile structure 10 or to wander within the textile structure 10.

[0038] The yarn constituting the fiber structure 10 preferably has an elongation of 10% or less, more preferably 1 to 5%, and even more preferably 1 to 3%. The elongation is measured in accordance with the JIS method of "JIS L 1095 General Spun Yarn Testing Method", specifically, a load is applied to a sample yarn using a tensile tester, and the elongation (cm) at the time the sample breaks is divided by the original length (cm) of the sample and expressed as a percentage (%). If the elongation of the yarn constituting the fiber structure 10 is 10% or less, more mites are attracted to the fiber structure 10, and a mite capture product with better capture performance can be provided. Note that the detailed mechanism by which the fiber structure 10 made of yarn with an elongation of 10% or less has an excellent effect of attracting and fixing mites is unknown, but it is expected that the elongation of the yarn constituting the fiber structure 10 is involved in the preference of mites.

[0039] The fiber material of the yarn constituting the fiber structure 10 is preferably a natural fiber of plant origin, and more preferably contains bast fiber and / or seed hair fiber. Examples of bast fiber include jute, linen, ramie, hemp, and kenaf. Yarns made of bast fiber have fluff and are highly attractive to mites, and can be used suitably. Among them, it is more preferable to use jute and ramie, which have extremely high attracting properties to mites, and it is even more preferable to use jute. Examples of seed hair fibers include cotton and kapok. When using yarns made of seed hair fibers, it is preferable to use carded yarns in order to generate appropriate fluff in the fiber structure 10. The elongation of yarns made of these bast fibers and seed hair fibers is 10% or less.

[0040] FIG. 2 is an enlarged image of the fiber structure 10. The fiber structure 10 is preferably knitted so that the yarns constituting the fiber structure 10 have a gap that allows mites to pass through. The fiber structure 10 is preferably a woven or knitted fabric, and the yarn density is preferably 10 to 100 yarns / 10 cm, more preferably 15 to 60 yarns / 10 cm, and even more preferably 30 to 50 yarns / 10 cm. Here, the "yarn density" refers to the number of warp or weft yarns contained in a 10 cm wide woven fabric when the fiber structure 10 is a woven fabric, and the number of courses or wells contained in a 10 cm wide knit fabric when the fiber structure 10 is a knitted fabric. If the yarn density of the fiber structure 10 is within the above range, as shown in the image of FIG. 2, the fluff 12 is appropriately present between the yarns 11 constituting the fiber structure 10, and more mites can be attracted. The intervals between the threads constituting the textile structure 10 need only be sufficient to provide breathability and allow mites to pass through, and are preferably 0.05 to 15 mm, more preferably 0.3 to 10 mm, and even more preferably 0.5 to 5 mm. If the intervals between the threads constituting the textile structure 10 are within the above range, then a suitable amount of fluff will be present between the threads constituting the textile structure 10, and a larger number of mites can be attracted.

[0041] The thickness of the fiber structure 10 is preferably 0.2 to 5 mm, more preferably 0.4 to 3 mm, and further preferably 0.5 to 1.5 mm. When the thickness of the fiber structure 10 is within the above range, the attracted mites tend to remain in the fiber structure 10, and the trapping performance becomes more excellent. Note that the thickness of the fiber structure 10 means the thickness of the fiber structure 10 itself, but when the fiber structure 10 is a single-layer woven or knitted fabric, the thickness of the yarn constituting the fiber structure 10 can be regarded as the thickness of the fiber structure 10.

[0042] The fiber structure 10 has a basis weight of 10 to 1500 g / m 2 It is preferable that the thickness is 20 to 1000 g / m 2 More preferably, it is 100 to 700 g / m 2 More preferably, the thickness is 200 to 600 g / m 2When the basis weight of the fiber structure 10 is within the above range, the attracted mites tend to remain within the fiber structure 10, and the trapping performance becomes more excellent.

[0043] Next, the inventors discovered that the attracting and capturing performance of the fiber structure 10 against mites can be evaluated by a new specific parameter determined from the thickness and basis weight of the fiber structure 10. Specifically, the thickness of the fiber structure 10 is a (mm), and the basis weight of the fiber structure 10 is b (g / m 2 ), the following equation (1): 0.1 ≦ (a 2 / b) × 100 ≦ 1.0 (1) It is preferable that the following formula (2): 0.2 ≦ (a 2 / b) × 100 ≦ 0.7 (2) When the fiber structure 10 satisfies the above formula, the fiber structure 10 has a moderate density of fibers, so that more mites are attracted to the fiber structure, and the trapping performance is improved.

[0044] In addition, the fiber structure 10 may be subjected to softening processing or the like to adjust the texture, or may be colored in a color that attracts mites or in a color that is difficult to notice when placed in a room, as long as this does not affect the function of attracting mites.

[0045] The adhesive body 20 is formed by forming an adhesive layer 22 on a sheet-like substrate 21, and mites that come into contact with the adhesive layer 22 are fixed. The adhesive layer 22 is preferably formed on both sides of the substrate 21, but may be formed on only one side. When the adhesive layer 22 is formed on both sides of the substrate 21, the opportunity for mites to come into contact with the adhesive layer 22 is increased, improving the capture performance. When the adhesive layer 22 is formed on only one side of the substrate 21, the handleability of the mite capture product 100 can be improved.

[0046] The substrate 21 preferably has both appropriate stiffness and flexibility so that the mite capturing product 100 can be easily inserted into even a small gap, and may be, for example, paper such as cardboard or corrugated cardboard, resin sheets such as PE, PP, PET, or PVC, or metal plates. The thickness of the substrate 21 is preferably 0.02 to 3 mm. If the thickness of the substrate 21 is within the above range, the substrate 21 has both appropriate stiffness and flexibility so that the substrate 21 can be easily inserted into even a small gap.

[0047] The adhesive layer 22 is formed by adhering a double-sided tape to the substrate 21 or by applying an adhesive to the substrate 21. As the adhesive, for example, a general-purpose adhesive such as a rubber-based adhesive, an acrylic-based adhesive, a hot melt-based adhesive, or a silicone-based adhesive can be used. Examples of the rubber-based adhesive include a natural rubber-based adhesive, a styrene-butadiene rubber-based adhesive, a recycled rubber-based adhesive, a polyisobutylene-butylene rubber-based adhesive, a polybutene-based adhesive, and a block copolymer-based adhesive. These adhesives can be used alone or in combination.

[0048] [Attraction and capture performance] It is preferable that the mite trapping product 100 attracts and captures mites that have invaded an area within a radius of 1 m. Here, "attracting and capturing" includes not only the state in which the attracted mites are fixed to the surface of the adhesive body 20, but also the state in which the attracted mites are retained inside the mite trapping product 100, particularly in the fiber structure 10. By attracting and capturing mites that have invaded an area within a radius of 1 m, mites approaching the mite trapping product 100 can be reliably captured and exterminated.

[0049] Although it depends on the breeding conditions of mites and the installation location, the mite trapping product 100 is capable of attracting and trapping mites that approach the mite trapping product 100 within 24 hours. 24 hours is a sufficiently short time for trapping mites, making the mite trapping product 100 practical to use.

[0050] The mite trapping product 100 is capable of attracting and trapping mites for at least 20 days, and up to 90 days. Although 20 days is a practical period for trapping mites, it is possible to trap and exterminate mites for a longer period. For example, the mite trapping product 100 can be designed to trap mites for 90 days by selecting the type of attractant and adhesive.

[0051] The mite trapping product 100 constructed as above includes the fiber structure 10 having fluff and the adhesive body 20 to which the mites are attached, and therefore has excellent trapping performance by first attracting the mites to the fiber structure 10 having fluff, and then allowing the attracted mites to remain in the fiber structure 10, or allowing the mites to wander around in the fiber structure 10 and then adhering to the adhesive body 20. Then, the mites captured by the mite trapping product 100 can be exterminated simply by disposing of the mite trapping product 100 as it is. The mite trapping product 100 does not use any chemicals such as insecticides or repellents, and can be used safely even by people who are sensitive to chemicals.

[0052] Second Embodiment [Tick trapping products] 3 is a schematic cross-sectional view of a mite-trapping product 200 according to a second embodiment of the present invention. The mite-trapping product 200 has an attractant 30 provided between the fiber structure 10 and the adhesive body 20, and otherwise has the same configuration as the mite-trapping product 100 described in the first embodiment. By providing the attractant 30, the mite-trapping product 200 has even better trapping performance due to a synergistic effect between the fiber structure 10, which has an attractive effect on mites, and the attractant 30.

[0053] The attractant 30 may be any one that has the effect of attracting mites, and may be, for example, a crushed powder or extract of food ingredients such as animal, plant, or yeast, or one that contains a fragrance ingredient that attracts mites. The attractant 30 may be a powder or granular food crushed product or a solidified product thereof, a food crushed product stored in a bag such as a breathable nonwoven fabric, or an extract adsorbed to various supports. For example, FIG. 3 illustrates an attractant 30 that is a solid tablet disposed between the fiber structure 10 and the adhesive body 20, but the attractant 30 may be a liquid extract that is sprayed or dropped onto the adhesive body 20, or that is added by kneading, adsorbing, impregnating, or the like into the fiber structure 10. In addition, when the adhesive layer 22 is formed by applying an adhesive to the substrate 21 in the adhesive body 20, the attractant 30 may be directly applied to the substrate 21 together with the adhesive.

[0054] <Third embodiment> [Tick-trapping products] 4 is a schematic cross-sectional view of a mite-trapping product 300 according to a third embodiment of the present invention. The mite-trapping product 300 has a fiber structure 10 covered with a breathable sheet 40, and otherwise has the same configuration as the mite-trapping product 200 described in the second embodiment.

[0055] The breathable sheet 40 is a sheet having holes of a size that allows mites to pass through. The breathable sheet 40 preferably does not have fluff. Although the detailed mechanism is unknown, when at least a part of the fiber structure 10 having fluff is covered with the breathable sheet 40 having no fluff, the attraction to mites is further improved, and the mites can easily enter the inside of the product, so that the mite capture product 300 has even better capture performance. The material of the breathable sheet 40 is not particularly limited as long as it does not repel mites, and for example, resin nets and nonwoven fabrics such as polyethylene, polyester, and nylon, woven or knitted fabrics made of chemical fibers, and woven or knitted fabrics made of natural fibers can be used. Examples of natural fibers used in the breathable sheet 40 include animal fibers such as wool and silk thread, and seed hair fibers. When seed hair fibers are used in the breathable sheet 40, it is preferable to use combed yarn to suppress fluff. Of these, as the breathable sheet 40, preferred are resin nets and nonwoven fabrics such as polyethylene, polyester, nylon, etc., and woven or knitted fabrics made of chemical fibers, more preferred are resin nets and nonwoven fabrics such as polyethylene, polyester, nylon, etc., and most preferred are resin nets such as polyethylene, polyester, nylon, etc.

[0056] The breathable sheet 40 is configured to cover at least a part of the fiber structure 10, and is configured, for example, as a bag in which the fiber structure 10 and the adhesive body 20 are enclosed. The provision of the breathable sheet 40 further improves the attracting ability of the mite-trapping product 300 to mites. In addition, since the fluff of the fiber structure 10 is not exposed on the outer surface of the product, the mite-trapping product 300 can be easily inserted into small gaps (for example, under a carpet that cannot be completely turned up, between futons stored in a closet, between the backrest and seat of a sofa, etc.), and further, irritation to the user's fingers during installation and disposal after use is reduced, making the product easy to use.

[0057] <How to capture mites> The mite capturing method of the present invention is to attract and capture mites by placing the above-mentioned mite capturing products 100 to 300 in or near the place where mites live. Since the mite capturing method of the present invention uses the mite capturing products 100 to 300 of the present invention, it is possible to provide a mite capturing method that is excellent in the effect of attracting mites and can reliably and safely capture and exterminate the attracted mites.

[0081] Comparative Example 7 A rubber-based hot melt adhesive was applied to both sides of a PET resin sheet with a thickness of 0.05 mm to prepare an adhesive body. Woven fabrics were laminated on both sides of the adhesive body to form a fiber structure, and a three-layer laminate was obtained. The fabric used for the fiber structure was a plain woven fabric made of wool yarn with a yarn density of 19 to 22 threads / 10 cm, with a thickness of 0.67 mm and a basis weight of 189 g / m. 2 The laminate was enclosed in a bag made of a polyethylene net (breathable sheet) to obtain a five-layered mite capture product of Comparative Example 7.

[0082] (1) Tick capture test The mite trapping products of Examples 1 to 16 and Comparative Examples 1 to 7 were cut into pieces of 3 cm x 3 cm to be used as test pieces, which were placed in the center of a 4.5 cm diameter glass petri dish (1.5 cm high). The 4.5 cm diameter petri dish was placed in the center of a 9 cm diameter (2 cm high) glass petri dish, and about 10,000 Dermatophagoides pteronyssinus were released into the 9 cm diameter glass petri dish, which was then left to stand in a dark place at room temperature of 25°C and humidity of 80%. After 24 hours, the number of mites attached to the adhesive body of the test piece was counted to determine the number of captures. The test was repeated three times for each of the mite trapping products of Examples 1 to 16 and Comparative Examples 1 to 7, and the average number of captures was calculated. As a control, only the adhesive used to prepare the mite trapping product of Example 1 was cut into a size of 3 cm x 3 cm and placed in the center of a glass petri dish with a diameter of 4.5 cm, and the same test as for the mite trapping products of Examples and Comparative Examples was performed, and the number of captured mites fixed to the adhesive was counted. The number of captured mites by the mite trapping products of Examples 1 to 16 and Comparative Examples 1 to 7 was divided by the number captured by the control to calculate the capture ratio.

[0083] (2) Growth rate For the mite-trapping products of Examples 1 to 16 and Comparative Examples 1 to 4 and 7, yarns were taken from the woven fabrics constituting the fiber structures, and the elongation (%) was measured in accordance with the JIS method of "JIS L 1095 General spun yarn testing method."

[0084] The details, test results, and measurement results of the mite-trapping products of Examples 1 to 16 and Comparative Examples 1 to 7 are shown in Table 1.

[0085] [Table 1]

[0086] As a result of the mite capture test, it was confirmed that the mite capture products of Examples 1 to 16, which use a woven fabric having fluff in the fiber structure, have a higher capture ratio and have an excellent attracting and fixing effect on mites compared to the mite capture products of Comparative Examples 1 to 7, which use a material without fluff in the fiber structure. In particular, the mite capture products of Examples 1 to 7 and 10, which use bast fibers, particularly jute or ramie, as the fiber material of the fiber structure, have a higher capture ratio than Examples 15 and 16, which use seed hair fibers such as cotton or kapok. The mite capture product of Example 8, which uses jute with low thread density and basis weight, also has a better capture ratio than Example 16, which uses kapok. Therefore, it is considered that a better attracting and fixing effect on mites can be obtained by using jute or ramie as the fiber material of the fiber structure.

[0087] The mite capturing products of Examples 1 to 16 used a fiber structure having a thickness a and a basis weight b (a 2 The parameter calculated by the formula (x,y)×100 was 0.13 to 0.78. Therefore, when a woven fabric having fluff is used for the fiber structure, it is considered that the above parameter in the range of about 0.1 to 1.0 will provide an excellent effect of attracting and fixing mites.

[0088] In the mite capture products of Examples 1 to 5, 7, and 8, in which jute was used as the fiber material of the fiber structure, the larger the basis weight, the higher the capture ratio. However, in the case of using jute as the fiber material of the fiber structure, the basis weight of the fiber structure is 946 g / m 2 The mite trapping product of Example 6 has a fiber structure with a basis weight of 600 g / m 2 Therefore, when jute is used as the fiber material of the fiber structure, the fiber structure has a basis weight of 72 to 600 g / m 2 Within this range, it is believed that the greater the basis weight of the fiber structure, the more excellent the effect of attracting and fixing mites.

[0089] The mite trapping products of Examples 13 and 14 are the mite trapping products of Examples 3 and 4 enclosed in a bag made of a polyethylene net (breathable sheet), respectively, and the polyethylene net used for the breathable sheet in the mite trapping products of Examples 13 and 14 is used alone as a fiber structure in the mite trapping product of Comparative Example 6. In this case, the capture ratios of the mite trapping products of Examples 13 and 14 are 162.2 and 160.6, respectively, which are greater than the total of the capture ratio of 138.4 in the mite trapping product of Example 3 and the capture ratio of 4.8 in the mite trapping product of Comparative Example 6 (143.2) and the total of the capture ratio of 121 in the mite trapping product of Example 4 and the capture ratio of 4.8 in the mite trapping product of Comparative Example 6 (125.8), and it was confirmed that the capture performance was improved. On the other hand, in the case of Comparative Example 7, in which the mite trapping product of Comparative Example 1, whose fiber material is wool, was enclosed in a bag made of a polyethylene net (breathable sheet), no effect of improving the capture performance was observed. From these results, it is believed that by covering a fiber structure having fluff with a breathable sheet without fluff, not only is the attracting and fixing effect of the fiber structure and the breathable sheet respectively achieved, but some kind of synergistic effect is also obtained, although the detailed mechanism is unknown, thereby improving the attracting and fixing effect against mites.

[0090] A mite capturing product having the characteristic configuration of the present invention (Example 17) and a product in which the adhesive body is enclosed in a bag (Comparative Example 8) were prepared, and a capturing distance test was carried out.

[0091] Example 17 A rubber-based hot melt adhesive was applied to both sides of a cardboard measuring 90 mm x 105 mm and a thickness of 2 mm to prepare an adhesive body. A kneaded solidified tablet (diameter 15 mm x thickness 3 mm) containing animal and vegetable food ingredients was placed on one side of the adhesive body, and a woven fabric measuring 100 mm x 115 mm was laminated on both sides of the adhesive body to prepare a fiber structure, thus obtaining a three-layer laminate. The fabric used for the fiber structure was a plain woven fabric made of jute yarn with a thread density of 43 to 47 threads / 10 cm, with a thickness of 0.86 mm and a basis weight of 255 g / m 2The laminate was enclosed in a bag made of polyethylene netting measuring 120 mm x 150 mm to obtain a five-layered mite trapping product of Example 17. The polyethylene netting had mesh spacing of 1 mm, a thickness of 0.03 mm, and a basis weight of 67 g / m 2 The polyethylene net had no fluff, and when a 10 cm line was placed on the polyethylene net, the number of fibers intersecting the line was 95 to 110.

[0092] Comparative Example 8 The adhesive used in Example 17 was enclosed in a bag made of the polyethylene net used in Example 17 to obtain the product of Comparative Example 8. That is, the product of Comparative Example 8 is a product that does not use the kneaded solidified tablet containing animal and vegetable food ingredients and the fiber structure, unlike the mite capture product of Example 17.

[0093] (3) Capture distance test FIG. 5 is a diagram for explaining the test method of the capture distance test. An unused polyester sheet X of 50 cm x 100 cm, which is 1 / 4 the size of a general futon mattress (100 x 200 cm), was laid and fixed on a wooden board. A groove was dug in the wooden board at the portion W corresponding to the outer periphery of the sheet X, and water was poured in to prevent mites from escaping and other mites from being mixed in. Here, as shown in FIG. 5, a corner A, a corner B, and a short side center C were set on the sheet X. The distance D1 from the corner B to the corner A was about 110 cm, and the distance D2 from the corner B to the short side center C was about 25 cm. The mite capture product Y of Example 17 was placed at the corner A of the sheet X and the short side center C of the sheet X, and about 1,000 Dermatophagoides pteronyssinus were released together with a medium at the corner B of the sheet X. Three such wooden boards were prepared and placed in a dark place at 25°C and 75% RH, and the number of mites attached to the adhesive of the mite-trapping product Y was counted after 24 hours and after 20 days. A similar trapping distance test was also conducted for the product of Comparative Example 8.

[0094] As a result of the capture distance test, the number of mites captured by the mite capture product Y of Example 17 installed at the center C of the short side after 24 hours was 252 to 334. In contrast, the number of mites captured by the product of Comparative Example 8 under the same conditions was 0. In addition, the number of mites captured by the mite capture product Y of Example 17 installed at the corner A after 20 days was 37 to 76. In contrast, the number of mites captured by the product of Comparative Example 8 under the same conditions was 0. From these results, it was confirmed that the mite capture product Y of Example 17 can attract and capture mites that have invaded an area of ​​at least 1 m. Since the distance D1 is approximately equivalent to the distance from the four corners of a general futon to the center where the diagonal lines intersect, it is considered that the mite capture product Y of Example 17 can effectively attract, capture, and exterminate mites living in the futon by installing it under the center of the futon in actual use. In addition, since the distance D2 is roughly equivalent to the distance from the edge of a typical mattress to the edge of the pillow, it is believed that placing the mite trapping product Y of Example 17 at the side of the pillow will attract, trap and exterminate mites living on the pillow within 24 hours. Furthermore, it is naturally believed that placing the mite trapping product Y at the shoulder or feet will also be sufficient to effectively attract, trap and exterminate mites. [Industrial Applicability]

[0095] The mite-trapping product and mite-trapping method of the present invention can be used for the purpose of exterminating mites lurking indoors. [Explanation of symbols]
