Description

Class Capture Artifacts, and Class Capture Methods

The present invention relates to a mite trapping product and a mite trapping method for trapping mites hidden in a house.

In recent years, the airtightness of the living environment has increased, and it has become a problem that mites are easy to reproduce. Since mites are the main cause of atopic dermatitis, asthma, allergic diseases, etc., general residents are looking for means and methods that can reliably and safely exterminate mites.

There is a method of using chemicals such as insecticides and repellents for extermination of mites. However, this method does not actively reduce the number of mites, so there is a problem of remaining dead bodies of mites. Also, people who are sensitive to chemicals are worried about the influence of chemicals, so they are looking for means and methods that can easily repel mites without using chemicals as much as possible.

Therefore, for repelling mites, there is a product (mite sheet) of the type that attracts and captures mites instead of killing insects or repelling mites (for example, refer to Patent Document 1). The mite sheet of Patent Document 1 is an attractant disposed on an adhesive, and these are held by air-permeable layers from top to bottom. According to Patent Document 1, mites are attracted to the attractant inside the two air-permeable layers, and then, are fixed on the adhesive to become trapped in the mite sheet.

[Patent Document 1] Japanese Patent Laid-Open No. 2009-89610

[Problem to be solved by the invention]

In a product of the type that attracts and captures the above-mentioned mites, it is extremely important to have an excellent attracting effect on the mites. If the attracting effect of mites is not sufficient, even if the capture product is close to the mites, the mites cannot be captured until the mites are surely induced to the adhesive. On the other hand, when the attractant effect on mites depends only on the attractant, if the effectiveness of the attractant is weakened by long-term use, the mite attractant effect will be greatly reduced.

In this regard, in the mite sheet of Patent Document 1, it is necessary for the mite to pass through the air-permeable layer in order to trap the mite with the adhesive. Thus, depending on the material or characteristics of the air-permeable layer, there is a possibility that the effect of attracting mites due to the attractant may be weakened. Also, since the mite sheet of Patent Document 1 requires an attractant, if the effect of the attractant disappears, there is a possibility that the mite may not even be attracted to the vicinity of the mite sheet.

In this way, it cannot be said that the mites-attracting effect of the mite sheet of Patent Document 1 is sufficient for attracting and capturing conventional mites, and there is still room for improvement.

The present invention has been made in view of the above-mentioned problems, and aims to provide a mite trapping product that is excellent in attracting mites and can capture and repel the lured mites reliably and safely, and a method for trapping mites . [Means to solve the problem]

In addition, in each figure, each constituent element of the mite trap product does not exactly reproduce the actual shape, size, positional relationship, size relationship of the thickness of each layer, scale, etc., but is exaggerated or simplified for the sake of ease of explanation. change. In addition, the present invention is not intended to be limited to the embodiments described below or the configurations described in the drawings.

＜First Embodiment＞ [Mite capture 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 the fiber structure 10 and the adhesive body 20 . In FIG. 1 , although two fibrous structures 10 are laminated on both sides of the adhesive body 20 as an example, the mite trap product 100 may be one in which only one fiber structure 10 is laminated on the adhesive body 20. The construction of the face on one side. Also, in FIG. 1 , although only one layer of the fiber structure 10 is laminated on one side of the sticker 20 as an example, the mite trapping product 100 may be laminated with two layers on one side of the sticker 20. The structure of the above-mentioned multi-layer fiber structure 10 .

The mite trapping product 100 is a product used for attracting and trapping the mites by being installed at or near a place where mites inhabit. In the mite trap product 100, the fibrous structure 10 itself attracts the mites and stays in the interior to fix the mites. The mite trapping product 100 can be captured by further laminating the fibrous structure 10 on the sticker 20 , and by contacting the attracted mite with the sticker 20 through the fibrous structure 10 , it can be captured. The mite trapping product 100 is preferably in the form of a sheet because it is spread under futons, tatami mats, rugs, carpets, etc. where mites inhabit, or inserted into the gap between the seat surface and the backrest of a sofa or the like. Although the plan view shape of the mite trapping product 100 is not particularly limited, it may be square, polygonal, circular, elliptical, etc. Such shapes are preferable because they are easy to handle.

In this way, the mite trapping product 100 can attract mites by the fibrous structure 10, so it can be configured as one that does not contain insecticides and/or repellents. Therefore, basically, the attracting effect of mites will not be greatly weakened. Also, since no pesticides and/or repellents are included, even those who are sensitive to chemicals can use it with peace of mind.

The fiber structure 10 is a raised fabric or knitted fabric. The weave of the fabric and knitted fabric is not particularly limited, but is preferably a plain weave. The mite trapping product 100 utilizes the phenomenon that mites are specifically attracted to the fiber structure 10 having fluff, effectively attracts the mites to the fiber structure 10, and keeps the attracted mites in the fiber structure 10 , or those who wander back into the fiber structure 10.

The elongation of the yarn constituting the fiber structure 10 is preferably 10% or less, more preferably 1 to 5%, and still more preferably 1 to 3%. The elongation rate is measured according to the JIS method of "JIS L 1095 General Spinning Test Method". Specifically, using a tensile testing machine, a load is applied to the yarn used as a sample, and the elongation (cm) when the sample is cut Divided by the original length of the sample (cm), and expressed as a percentage (%). If the elongation rate of the yarn constituting the fiber structure 10 is 10% or less, more mites are attracted to the fiber structure 10 and a mite trapping product with better trapping performance can be provided. Still, the detailed mechanism by which the fiber structure 10 made of yarn with an elongation rate of 10% or less is excellent in attracting and fixing the mites is not clear, but it is expected that the yarn constituting the fiber structure 10 Elongation is related to the mite's predilection.

The fiber material constituting the yarn of the fiber structure 10 is preferably a vegetable natural fiber, and more preferably includes bast fiber and/or seed hair fiber. Examples of the bast fiber include jute, linen, ramie, hemp, and kenaf. The yarn made of bast fibers has fluff, so it is suitable for use due to its high attractivity to mites. Among them, the attractivity of mites is extremely high, so it is better to use jute and ramie, and even more preferably to use jute. numb. Cotton, kapok, etc. are mentioned as a seed wool fiber. When using the yarn which consists of seed wool fiber, since it produces moderate fluff to the fiber structure 10, it is preferable to use a card yarn. The elongation of the yarn composed of such bast fiber and seed wool fiber is 10% or less.

FIG. 2 is an enlarged image of the fiber structure 10 . Although the fiber structure 10 is a yarn constituting the fiber structure 10, it is preferably woven so as to have a space that can pass between mites. In addition, the fiber structure 10 is preferably a fabric or a knitted fabric, and its yarn density is preferably 10-100 yarns/10cm, more preferably 15-60 yarns/10cm, and even more preferably 30-50 yarns/10cm. The so-called "yarn density" here refers to the number of warp or weft yarns contained in a fabric with a width of 10 cm when the fiber structure 10 is a fabric, and the number of transverse loops contained in a fabric with a width of 10 cm when the fiber structure 10 is a knitted fabric. or the number of longitudinal coils. If the yarn density of the fiber structure 10 is in the above-mentioned range, as shown in the image of FIG. 2 , fluff 12 is moderately present between the yarns 11 constituting the fiber structure 10, and more mites can be attracted. Also, if the distance between the yarns constituting the fiber structure 10 is air permeable and allows the passage of mites, it is preferably 0.05 to 15 mm, more preferably 0.3 to 10 mm, and even more preferably 0.5 to 5 mm. If the distance between the yarns constituting the fiber structure 10 is within the above-mentioned range, there will be moderate fluff between the yarns constituting the fiber structure 10 , and more mites can be attracted.

The thickness of the fiber structure 10 is preferably from 0.2 to 5 mm, more preferably from 0.4 to 3 mm, and still more preferably from 0.5 to 1.5 mm. If the thickness of the fibrous structure 10 is within the above-mentioned range, the attracted mites are likely to stay in the fibrous structure 10, and the trapping performance is more excellent. Still, the thickness of the so-called fiber structure 10 means the thickness of the fiber structure 10 itself, but when the fiber structure 10 is a single-layer fabric or knitted fabric, the thickness of the yarn constituting the fiber structure 10 can be regarded as The thickness of the fiber structure 10.

The weight per unit area of the fiber structure 10 is preferably 10-1500 g/m ² , more preferably 20-1000 g/m ² , still more preferably 100-700 g/m ² , most preferably 200-600 g/m ² . If the weight per unit area of the fiber structure 10 is within the above-mentioned range, the attracted mites are likely to stay in the fiber structure 10, and it becomes more excellent in trapping performance.

Next, the present inventors found that the performance of attracting and trapping mites can be evaluated by using novel specific parameters obtained from the thickness and weight per unit area of the fibrous structure 10 . Specifically, when the thickness of the fiber structure 10 is defined as a (mm), and the weight per unit area of the fiber structure 10 is defined as b (g/m ² ), it is preferable to satisfy the following formula (1): 0.1 ≦(a ² /b)×100≦1.0 •••(1) It is more preferable to satisfy 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 moderately dense fibers, more mites are attracted to the fiber structure, and the fiber structure has better trapping performance.

Furthermore, in the fiber structure 10, as long as the function of attracting mites is not affected, in order to adjust the texture, softening processing, etc. can be implemented, or the color that is easy to attract mites or the color that is inconspicuous when installed in the room can be processed. coloring.

The adhesive body 20 forms an adhesive layer 22 on a sheet-shaped base material 21, and contacts the adhesive layer 22 to fix the mites. Although the adhesive layer 22 is preferably formed on both surfaces of the substrate 21, it may be formed on only one surface. When the adhesive layer 22 is formed on both sides of the base material 21, the chances of the mites contacting the adhesive layer 22 increase, and the trapping performance can be improved. When the adhesive layer 22 is formed on only one side of the base material 21, the operability of the mite trapping product 100 can be improved.

The base material 21 is preferably a mite trap product 100 that is easy to insert with only a slight gap, and has both moderate rigidity and flexibility. For example, paper such as thick paper, corrugated paper, PE, PP, PET, PVC, etc. can be used. Resin sheets and metal plates, etc. The thickness of the base material 21 is preferably 0.02-3 mm. If the thickness of the base material 21 is within the above-mentioned range, it will have both moderate rigidity and flexibility that are easy to insert with only a slight gap.

The adhesive layer 22 is formed by attaching a double-sided adhesive tape to the base material 21 , or coating an adhesive on the base material 21 . As the adhesive, for example, general-purpose ones such as rubber-based adhesives, acrylic adhesives, hot-melt adhesives, and silicone-based adhesives can be used. Examples of rubber-based adhesives include natural rubber-based adhesives, styrene-butadiene rubber-based adhesives, recycled rubber-based adhesives, polyisobutylene-butene rubber-based adhesives, polybutylene-based adhesives, and embedding adhesives. Segment copolymer adhesives, etc. These adhesives can be used alone or in combination.

[attraction capture performance] The mite trapping product 100 is preferably used to lure and trap mites that have invaded within a radius of 1 m. The so-called "attraction and capture" here is not only the state of fixing the attracted mites on the surface of the adhesive body 20, but also includes keeping the lured mites inside the mite capture product 100, especially the fibrous structure. Status in 10. By attracting and capturing the mites that have invaded the area within a radius of 1 m, the mites approaching the mite trapping product 100 can be surely captured and repelled.

Although the mite trapping product 100 also varies depending on the breeding status of the mites or the place where it is installed, it can lure and capture the mites that are close to the mite trapping product 100 within 24 hours. If 24 hours is the time for trapping mites, if it is very short, the mite trapping product 100 is practical.

The mite trapping product 100 can pass through at least 20 days or more than 90 days, and can also attract and capture mites. Although 20 days is practical as the period of continuous capture of mites, mites can be captured and expelled over a longer period of time. For example, the mite trapping product 100 can also be designed to trap mites for 90 days by selecting the type of attractant or adhesive.

In the mite trapping product 100 constituted as above, by including: the fiber structure 10 having fluff and the adhesive body 20 for fixing the mites, first, by attracting the mites to the fiber structure having fluff 10. After the lured mites stay in the fiber structure 10, or wander back into the fiber structure 10, the mites are fixed on the adhesive body 20 and become excellent in capturing performance. Moreover, the mites captured by the mite trapping product 100 can be repelled only by directly discarding the mite trapping product 100 . Furthermore, since the mite trapping product 100 does not use pesticides or repellents, even people who are sensitive to chemicals can use it with peace of mind.

<Second Embodiment> [Mite capture products] Fig. 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 is provided with the attractant 30 between the fiber structure 10 and the adhesive body 20, and has the same configuration as the mite trapping product 100 described in the first embodiment. The mite trapping product 200 is provided with an attractant 30 and has a synergistic effect between the fibrous structure 10 having an effect of attracting mites and the attractant 30 , so that the trapping performance is more excellent.

The attractant 30 can be any one that has the effect of attracting mites, for example, it can use pulverized powder or extract containing animal, vegetable, yeast and other food ingredients, or a fragrance ingredient that has the effect of attracting mites. The attractant 30 may be powdery or granular food grinds or solidified ones, food grinds stored in air-permeable non-woven bags, extracts adsorbed on various holders, and the like. For example, in FIG. 3 , although the attractant 30 of a solid lozenge disposed between the fiber structure 10 and the adherend 20 is illustrated, the attractant 30 can be formed by applying a liquid extract to the adherend 20. Spraying treatment, dripping treatment, or treatment of kneading, adsorption, impregnation, etc. on the fibrous structure 10 is added. In addition, when the adhesive 30 is coated on the base material 21 by the adhesive body 20 to form the adhesive layer 22, it may be directly coated on the base material 21 together with the adhesive.

<Third Embodiment> [Mite capture products] Fig. 4 is a schematic sectional view of a mite trapping product 300 according to a third embodiment of the present invention. The mite trapping product 300 is one in which the fiber structure 10 is covered with the air-permeable sheet 40, and has the same configuration as the mite trapping product 200 described in the second embodiment.

The air-permeable sheet 40 is a sheet having pores of a size through which mites can pass. The air-permeable sheet 40 preferably has no fluff. Although the detailed mechanism is unclear, when at least a part of the fiber structure 10 with fluff is covered with the air-permeable sheet 40 without fluff, the attractivity to mites is further increased, and mites become more likely to invade the interior of the product. , so the mite trapping product 300 has better trapping performance. The material of the air-permeable sheet 40 is not particularly limited if it does not repel mites. For example, resin nets or non-woven fabrics such as polyethylene, polyester, and nylon, and fabrics or braids made of chemical fibers can be used, and Fabrics or braids made of natural fibers. Examples of natural fibers used in the air-permeable sheet 40 include wool, silk, and other animal fibers and seed wool fibers. When using the seed hair fiber for the air-permeable sheet 40, it is preferable to use a combed yarn in order to suppress fuzzing. Among these, as the air-permeable sheet 40, resin nets or non-woven fabrics such as polyethylene, polyester, and nylon are preferable, and fabrics or braids woven by chemical fibers are preferably polyethylene, polyester, and nylon. Resin nets or non-woven fabrics such as polyethylene, polyester and nylon are the best.

The air-permeable sheet 40 is configured to cover at least a part of the fiber structure 10 , for example, as a bag enclosing the fiber structure 10 and the adhesive 20 . The mite trapping article 300 further enhances the attractivity of the mite by providing the air-permeable sheet 40 . Also, since the fluff of the fiber structure 10 will not be exposed to the outer surface of the product, the mite trapping product 300 can be easily inserted into only a slight gap (such as under a blanket that cannot be turned up at all, between bedding stored in a closet) space, the gap between the backrest of the sofa and the seat surface, etc.), and furthermore, during installation or disposal after use, the irritation to the user's fingers is reduced, and it is excellent in usability.

＜How to capture mites＞ The mite trapping method of the present invention is to lure those who trap mites by arranging the above-mentioned mite trapping products 100-300 at or near places where mites inhabit.

The fabric used for the fiber structure is a plain weave fabric made of wool yarn at a yarn density of 19 to 22 yarns/10cm, with a thickness of 0.67mm and a weight per unit area of 189g/m ² . The mite capture product of Comparative Example 7 consisting of five layers was obtained by enclosing the laminate in a bag made of a polyethylene net (air-permeable sheet). In polyethylene netting, the interval between grids is 1mm, the thickness is 0.03mm, and the weight per unit area is 67g/ ^m2 . The polyethylene mesh does not have fluff, and when a 10 cm line segment is set on the polyethylene mesh, the number of fibers intersecting the line segment is 95 to 110.

(1) Mite capture test Regarding the mite trapping products of Examples 1 to 16, and the mite trapping products of Comparative Examples 1 to 7, those cut out to a size of 3 cm × 3 cm were used as test pieces, and placed in a glass tray (height 1.5 cm) with a diameter of 4.5 cm. cm). In the center of a glass shallow dish with a diameter of 9 cm (height 2 cm), set the previous shallow dish with a diameter of 4.5 cm, and put about 10,000 dust mites inside the glass shallow dish with a diameter of 9 cm, at room temperature 25 ° C , Stand in a dark place with a humidity of 80%. After 24 hours, count the number of mites fixed on the adhesive body on the test piece as the number of captures. The test was repeated three times for the mite trapping products of Examples 1 to 16 and the mite trapping products of Comparative Examples 1 to 7, and the average value of the number of traps was calculated. As a comparison, the sticky body used only in the manufacture of the mite trapping product of Example 1 was cut out to a size of 3 cm × 3 cm, and placed in the center of a glass tray with a diameter of 4.5 cm. The same test was carried out on the captured product, and the number of captured mites fixed on the adhesive body was counted. The number of captures by the mite trapping products of Examples 1 to 16 and the mite trapping products of Comparative Examples 1 to 7 was calculated by dividing the value divided by the comparative capture number as the capture ratio.

(2) Elongation Regarding the mite trapping products of Examples 1 to 16, and the mite trapping products of Comparative Examples 1 to 4, and 7, the yarn was collected from the fabric constituting the fiber structure according to "JIS L 1095 General Spinning Test Method" JIS method, measuring elongation (%).

Table 1 shows the details, test results, and measurement results of the mite trapping products of Examples 1-16 and Comparative Examples 1-7.

The results of the mite trapping test, comparing the mite trapping products of Examples 1 to 16 in which the fabric with fluff was used for the fiber structure, and the mite trapping products of Comparative Examples 1 to 7 in which the fabric without fluff was used for the fiber structure , it is confirmed that the capture is relatively large, and it has an excellent attracting and fixing effect on mites. Among them, as the fiber material of the fiber structure, among bast fibers, especially the mite trapping products of Examples 1 to 7 and 10 using jute or ramie, and Examples 15 and 10 using cotton or kapok of seed hair fibers. 16 compares, whichever becomes the larger capture compare. The mite trapping product of Example 8, which uses jute with low yarn density and low unit area weight, also has a better capture ratio than Example 16, which uses kapok. Therefore, it is considered that by using jute or ramie as the fiber material of the fiber structure, a more excellent attracting and fixing effect on mites is obtained.

The parameters obtained by using (a ² /b)×100 of the thickness a and the weight per unit area b of the fibrous structure of the mite trapping products of Examples 1 to 16 are 0.13 to 0.78. Therefore, it is considered that when the fiber structure uses a fabric with fluff, the above-mentioned parameter is approximately in the range of 0.1 to 1.0, so that the effect of attracting and fixing mites becomes excellent.

In the mite trapping products of Examples 1 to 5, 7, and 8 using jute as the fiber material of the fiber structure, the larger the weight per unit area, the larger the trapping ratio. However, although jute is used as the fiber material of the fiber structure, the mite trapping product of Example 6 whose fiber structure has a weight per unit area of 946 g/m ² has a weight per unit area of the fiber structure of 600g/m ² The mite capture product of embodiment 2 becomes the one with the smaller capture ratio. Therefore, when jute is used as the fiber material of the fiber structure, the weight per unit area of the fiber structure is greater in the range of 72 to 600 g/m ² . The effect becomes the superior one.

The mite trapping products of Examples 13 and 14 are those in which the mite trapping products of Examples 3 and 4 are respectively enclosed in bags made of polyethylene mesh (breathable sheet), and the mite traps of Examples 13 and 14 The trapping product is a polyethylene net made of air-permeable sheets, and the mite trapping product in Comparative Example 6 is used alone as a fiber structure. In this case, it was confirmed that the capture ratios of the mite trapping products of Examples 13 and 14 were 162.2 and 160.6, respectively, compared with the capture ratio of 138.4 of the mite trapping product of Example 3 and the mites of Comparative Example 6. The total capture ratio of 4.8 of the capture product is 143.2, or the capture ratio of the mite capture product of Example 4 is 121, and the total capture ratio of 4.8 of the mite capture product of Comparative Example 6 is 125.8, which improves the capture performance. On the other hand, in Comparative Example 7 in which the mite trapping product of Comparative Example 1 in which the fiber material was wool was enclosed in a bag made of polyethylene mesh (air-permeable sheet), no effect of improving the trapping performance was confirmed. From these results, it is considered that by covering the fiber structure with fluff with an air-permeable sheet without fluff, not only the individual attraction and fixation effect of the fiber structure and the air-permeable sheet can be obtained, but also the detailed mechanism Although it is not clear, some kind of synergistic effect is also obtained, and the attracting and fixing effect on mites is improved.

A mite trapping product (Example 17) having the characteristic constitution of the present invention and a product (Comparative Example 8) in which an adhesive body is sealed in a bag were prepared, and the trapping distance test was carried out.

[Example 17] A rubber-based hot-melt adhesive was applied to both sides of thick paper with a thickness of 2 mm and a size of 90 mm×105 mm to prepare an adhesive body. Arrange kneaded and solidified lozenges (diameter 15mm×thickness 3mm) containing animal and vegetable food ingredients on one side of the sticker, and then laminate fabrics with a size of 100mm×115mm on both sides of the sticker to form a fiber structure body to obtain a laminated body consisting of three layers. The fabric used for the fiber structure is made of jute yarn at a yarn density of 43 to 47 yarns/10cm to form a plain weave fabric with a thickness of 0.86mm and a weight per unit area of 255g/m ² . The mite capture product of Example 17 which consists of 5 layers was obtained by enclosing the laminated body in the bag body which consists of the polyethylene mesh of size 120mm*150mm. For polyethylene netting, the mesh interval is 1mm, the thickness is 0.03mm, and the weight per unit area is 67g/ ^m2 . The polyethylene mesh does not have fluff, and when a 10 cm line segment is set on the polyethylene mesh, the number of fibers intersecting the line segment is 95 to 110.

[Comparative Example 8] The adhesive used in Example 17 was enclosed in a bag made of the polyethylene mesh used in Example 17 to obtain the product of Comparative Example 8. That is, the product of Comparative Example 8 is the one that does not use the kneaded solidified lozenge and fiber structure containing animal and plant food ingredients with respect to the mite trap product of Example 17.

(3) Capture distance test Fig. 5 is a diagram illustrating the test method of the capture distance test. An unused polyester sheet X of 50 cm x 100 cm, which is 1/4 of the general mattress size (100 x 200 cm), was laid on a wooden board and fixed. The part W corresponding to the outer periphery of the sheet X is a groove dug in a wooden board, and water is poured in order to prevent mites from escaping or mixing with other mites. Here, as shown in FIG. 5 , the corner A, the corner B, and the short-side central part C are set for the sheet X. As shown in FIG. The distance D1 from the corner B to the corner A is about 110 cm, and the distance D2 from the corner B to the center C of the short side is about 25 cm. On the corner A of the sheet X and the center C of the short side of the sheet X, the mite trapping product Y of Example 17 was placed, and on the corner B of the sheet X, about 1,000 dust mites were placed together with the culture medium. Three of these boards were prepared and set in a dark place at 25° C. and 75% RH, and after 24 hours and 20 days, the mites fixed to the adherends of the mite-trapping product Y were counted. For the product of Comparative Example 8, the same capture distance test was also carried out.

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 part C of the short side after 24 hours was 252 to 334. On the other hand, the number of mites captured by the product of Comparative Example 8 under the same conditions was zero. Moreover, the number of mites captured by the mite trapping product Y of Example 17 installed at the corner A after 20 days was 37 to 76. On the other hand, the number of mites captured by the product of Comparative Example 8 under the same conditions was zero. From these results, it was confirmed that the mite trapping product Y of Example 17 can attract and trap mites that have invaded an area within at least 1 m. Since the distance D1 is approximately equivalent to the distance from the corners of the four sides of a general mattress to the central part where the diagonal lines intersect, it is considered that the mite trapping product Y of Example 17 is actually used by being installed on the mattress Near the center, it can effectively attract and trap the mites inhabiting the mattress and repel them. Also, since the distance D2 is approximately equivalent to the distance from the end of a general mattress to the end of a pillow, it is considered that by placing the mite trapping product Y of Example 17 on the side of the pillow, it is possible to inhabit the mite between the pillows. Mites are attracted and captured within 24 hours and can be repelled. Furthermore, although it is a matter of course, it is considered that even if the mite trapping product Y is placed on the shoulder or the foot, the mites can be sufficiently and effectively attracted and captured and repelled.
