Description
本発明は、病原性のウイルス、細菌、菌類が発生した又は発生した可能性があるとき、その地域からの他の地域への拡散を防止するため、自動車、原動機付自転車、軽車両などの車両に装着されるタイヤの接地面を消毒及び殺菌するために使用する消毒マットに関する。 The present invention is directed to vehicles such as automobiles, motorbikes, and light vehicles in order to prevent the spread of pathogenic viruses, bacteria, and fungi from the area to other areas when the pathogenic virus, bacteria, or fungus has occurred. The present invention relates to a disinfecting mat used for disinfecting and disinfecting a ground contact surface of a tire mounted on a tire.
ヒトや動物に病気を引き起こす原因となる口蹄疫ウイルス、インフルエンザウイルス、鳥インフルエンザウイルス、Ｏ−１５７ウイルス、ノロウイルス、ロタウイルスなどのウイルス、黄色ブドウ球菌、緑膿菌、病原性大腸菌などの細菌、カビ毒を発生する菌類などは、空気中に飛散しているのみならず地面にも堆積する。ひとたび、それら病原性のウイルス、細菌、菌類の発生又はその可能性があると、自動車、原動機付自転車、軽車両などの車両が、その発生した又は発生した可能性がある地域を通行する際に、それら車両に装着されるタイヤの接地面に付着し、他の地域まで拡散又は蔓延し、ヒトや動物に感染し発病するリスクが大きくなる。 Viruses such as foot-and-mouth disease virus, influenza virus, avian influenza virus, O-157 virus, norovirus, rotavirus, and other bacteria that cause disease in humans and animals, bacteria such as Staphylococcus aureus, Pseudomonas aeruginosa and pathogenic Escherichia coli, mold toxin Fungi and the like that generate are deposited not only in the air but also on the ground. Once these pathogenic viruses, bacteria, fungi have occurred or are likely to occur, vehicles such as automobiles, motorbikes, and light vehicles pass through the area where they have occurred or may have occurred. They attach to the ground contact surfaces of tires mounted on these vehicles, spread or spread to other areas, and increase the risk of infecting humans and animals.
このため、それらが発生した又はその可能性がある地域では、自治体等が、車両ドライバーに対して、管内の消毒ポイントでの消毒を徹底するように呼びかけている。その消毒ポイントでは、車両全体に消毒剤を噴霧する方法、道路を掘削して窪地をつくりその中に消毒剤を満たして車両を通行させて車両のタイヤを消毒する方法、絨毯などに消毒剤を塗布しその上に車両を通行させ車両のタイヤの道路との接地面を消毒する方法などが採られている。 For this reason, in areas where they have occurred or are likely to occur, local governments or the like call on vehicle drivers to thoroughly disinfect the disinfection points in the pipes. At the disinfection point, a method of spraying a disinfectant on the entire vehicle, a method of excavating a road to create a depression, filling the disinfectant into the vehicle and passing the vehicle to disinfect the tires of the vehicle, disinfecting a carpet, etc. A method of disinfecting a ground contact surface with a road of a vehicle tire by applying the vehicle and passing the vehicle on the vehicle is used.
このような車両消毒装置として、特許文献１では、消毒液供給装置から供給される消毒剤が流れる配管とその配管に消毒剤を車両全体に対して噴射等させる噴射ノズルなどを有する車両消毒装置が公開されている。
As such a vehicle disinfection device, in
また、特許文献２では、不織布などのマット本体にアルカリ性化合物の水溶液を供給した後に乾燥させるアルカリ性化合物含浸工程を経て製造される足踏み用の殺菌マットが公開されている。
Further,
また、特許文献３では、マット本体とマット本体を収納した台座からなり、マット本体がスポンジ構造体で構成されており、マット本体に消毒液、洗浄液、アルカリ液、酸性液、消臭液、防カビ液などの薬液を含浸した足踏み用の薬液マットが公開されている。
Moreover, in
上述の特許文献１に記載の発明では、通行する車両の全体に消毒剤を塗布することができるが、自治体等が行っている消毒ポイントでの消毒が法律上規定されている義務ではないために、消毒剤による車体表面の腐食や劣化又は塗料の退色などの悪影響を恐れて、その消毒ポイントで消毒を受けないドライバーがおり、病原性のウイルス、細菌、菌類の拡散又は蔓延を防止する実行性について問題があった。また、それらの病原性のウイルス、細菌、菌類の発生は、事前に予期することが難しく、発覚したときにはどれくらいの範囲、地域で拡がっているか分からないことがあるため、消毒する装置又は器具を複数台保有しておく必要がある。しかし、特許文献１に記載の発明を複数台保有するにはその大きさのため保管する場所が制限され十分な台数を常時備蓄しておけない問題もあった。
In the invention described in the above-mentioned
また、車体への種々の悪影響を防ぐために、道路を掘削し窪地をつくりその中に消毒剤を満たして車両を通行させて車両のタイヤを消毒する方法も採られているが、病原性のウイルス、細菌、菌類の発生のたびに道路工事が必要であり、迅速な対応が求められるそれらの拡散又は蔓延対策としては時間が掛かり過ぎ、また工事費用が嵩むという問題があった。また、同じ車両でも軽自動車と大型トラックでは、車体の大きさに差があり、ともに不都合なく消毒することが難しい問題があった。すなわち、一方で車体の大きい大型トラックのタイヤの接地面を消毒するために道路の窪地に十分な消毒剤を満たすと、消毒液が車体の小さい軽自動車の車体又はディスクブレーキに付着し腐食又は劣化等の悪影響を及ぼす恐れがある。他方で車体の小さい軽自動車の車体等に腐食等の悪影響を及ぼさない程度に道路の窪地に消毒液を蓄えると、大型トラックのタイヤの接地面１周すべてを十分に消毒できない恐れや、消毒液が揮発又は消費により不足しがちになり頻繁に消毒剤を補充する必要性があることから作業者の労力負担が増え作業者の薬傷の危険性が増える等の問題があった。 In addition, in order to prevent various adverse effects on the car body, a method of excavating roads, creating depressions, filling them with disinfectant and passing the vehicle through to disinfect the tires of the vehicle has been adopted. In addition, road construction is required every time the bacteria and fungi are generated, and there is a problem that it takes too much time as a countermeasure for spreading or spreading that requires a quick response and the construction cost increases. Moreover, even in the same vehicle, there is a difference in the size of the vehicle body between a light vehicle and a large truck, and there is a problem that it is difficult to disinfect without inconvenience. That is, on the other hand, if the road depression is filled with a sufficient disinfectant to disinfect the ground contact surface of a large truck tire with a large vehicle body, the disinfectant will adhere to the vehicle body or disc brake of a light vehicle with a small vehicle body and corrode or deteriorate. There is a risk of adverse effects such as. On the other hand, if the disinfectant solution is stored in the depressions of the road to such an extent that it does not adversely affect the car body of a light vehicle with a small body, the entire ground contact surface of the tire of a large truck may not be disinfected sufficiently. However, there is a problem that the labor burden of the worker increases and the risk of chemical burns of the worker increases because the disinfectant tends to be insufficient due to volatilization or consumption.
また、絨毯などに薬剤を塗布しその上に車両を通行させ車両のタイヤの道路との接地面を消毒する方法では、消毒剤が絨毯の内部に十分に浸透しないために消毒剤の消費が早く、またその絨毯などの表面に液溜まりが生じやすく車両の通行速度が速いと車両がスリップする恐れがあり、そのような理由から多くの消毒剤を撒くことができずに乾燥しやすくなり、車両のタイヤの接地面を十分に消毒することができないという問題があった。また、一方車両の通行速度を制限し、車両のスリップを防ぐために消毒液を大量に撒いたとしても、絨毯等では十分に浸透しないためにその表面から流れ落ち周囲への環境汚染の可能性もありやはり使用するときにおいて問題があった。 In addition, in the method of applying a chemical to a carpet and passing the vehicle over the carpet to disinfect the contact surface of the vehicle tire with the road, the disinfectant consumes quickly because the disinfectant does not sufficiently penetrate into the interior of the carpet. In addition, the surface of the carpet or the like is liable to cause liquid pooling, and if the vehicle travels at a high speed, the vehicle may slip. For this reason, a lot of disinfectant can not be sowed and it is easy to dry. There was a problem that the contact surface of the tire could not be disinfected sufficiently. In addition, even if a large amount of disinfectant is sprayed to limit the vehicle speed and prevent the vehicle from slipping, it does not penetrate sufficiently with carpets, etc., so there is a possibility of environmental pollution to the surroundings. There was also a problem when using it.

以下、本発明に係る車両消毒用マットに関する実施形態について詳しく説明する。 Hereinafter, an embodiment relating to a vehicle disinfection mat according to the present invention will be described in detail.
本発明の三次元網目構造のシートは、好ましくは不織布、布、繊維スポンジ、合成樹脂スポンジ、編み物、織物など内部に空隙を有するシートであり、より好ましくは不織布である。 The sheet having a three-dimensional network structure of the present invention is preferably a non-woven fabric, a cloth, a fiber sponge, a synthetic resin sponge, a knitted fabric, a woven fabric or the like having a void inside, and more preferably a non-woven fabric.
また、前記三次元網目構造のシートの目付は、好ましくは２５００〜３４００ｇ／ｍ２、さらに好ましくは２８００〜３２００ｇ／ｍ２である。複数の車両の通行にも破損、摩耗することなく一定期間継続的に使用するため、また適度に柔軟性を保ち凹凸のある路面にフィットするため、保管時にはロール状に巻いたり折り曲げたりできるためには、この範囲の目付の三次元網目構造のシートが好ましい。目付が小さ過ぎると、重量の重い車両が通行すると破損、摩耗などにより耐久性に劣り、目付が大き過ぎると消毒剤を吸収、保持する能力が低い。なお、目付とは、織物や編み物、不織布の単位面積当たりの重さであり、ここでは１ｍ２当たりの重さをｇ（グラム）で示している。
The basis weight of the sheet having the three-dimensional network structure is preferably 2500 to 3400 g / m 2 , more preferably 2800 to 3200 g / m 2 . Because it can be used continuously for a certain period of time without being damaged or worn even in the passage of multiple vehicles, and it can be rolled or folded in a roll during storage in order to fit moderately flexible and uneven road surfaces A sheet having a three-dimensional network structure with a basis weight in this range is preferable. If the basis weight is too small, if a heavy vehicle passes, it will be inferior in durability due to damage, wear, etc. If the basis weight is too large, the ability to absorb and retain the disinfectant will be low. The basis weight is the weight per unit area of the woven fabric, the knitted fabric, or the nonwoven fabric , and here, the weight per 1 m 2 is indicated by g (gram).
また、前記三次元網目構造のシートの飽和含水量は、好ましくは８〜１２Ｌ／ｍ２であり、さらに好ましくは９〜１１Ｌ／ｍ２である。飽和含水量が小さ過ぎると、含有できる消毒液が少ないので頻繁に消毒液を補給する機会が増えるため作業が煩雑になり作業者の薬傷の危険性が高くなり、一方飽和含水量が大き過ぎると、三次元網目構造のシートの内部の空間が大きくなるため強度が弱くなり頻繁に往来する車両の重さに耐えられることができず破損、摩耗など耐久性に乏しくなる。 The saturated water content of the sheet having the three-dimensional network structure is preferably 8 to 12 L / m 2 , and more preferably 9 to 11 L / m 2 . If the saturated water content is too small, the amount of disinfecting liquid that can be contained is small, so the opportunity to replenish the disinfecting liquid frequently increases and the work becomes complicated and the risk of burn injury for workers increases, while the saturated water content is too large. In this case, the space inside the sheet having the three-dimensional network structure is increased, so that the strength is weakened and the weight of the vehicle that frequently travels cannot be withstood, resulting in poor durability such as breakage and wear.
また、本発明の車両消毒用マットは、使用した後に焼却廃棄する際の利便性から、可燃性素材の前記三次元網目構造のシートが用いられる。素材としては、前記焼却廃棄時にダイオキシンなどの人体又は環境に有毒な物質を発生させないために好ましくはアラミド繊維、セルロース繊維、ナイロン繊維、ビニロン繊維、ポリエステル繊維、ポリオレフィン繊維、レーヨン繊維などの合成繊維などが用いられる。また、耐擦傷性、耐候性、耐光性、耐薬品性などの諸物性及び経済性の観点から、さらに好ましくは、ポリプロピレン樹脂、ポリエチレン樹脂である。 The vehicle disinfection mat of the present invention uses the three-dimensional mesh structure sheet of combustible material for the convenience of incineration and disposal after use. The material is preferably synthetic fiber such as aramid fiber, cellulose fiber, nylon fiber, vinylon fiber, polyester fiber, polyolefin fiber, rayon fiber, etc. in order not to generate toxic substances such as dioxins at the time of incineration and disposal. Is used. Further, from the viewpoints of various physical properties such as scratch resistance, weather resistance, light resistance, chemical resistance, and economical efficiency, polypropylene resin and polyethylene resin are more preferable.
また、前記三次元網目構造のシートとして好ましい不織布の製造方法として、一般にサーマルボンド法、ケミカルボンド法、ニードルパンチ法、スパンレース法、ステッチボンド法、スチームジェット法などが知られているが、厚さの設計が容易であるサーマルボンド法、ニードルパンチ法が好ましい。 Further, as a preferable method for producing a nonwoven fabric as the sheet having the three-dimensional network structure, a thermal bond method, a chemical bond method, a needle punch method, a spun lace method, a stitch bond method, a steam jet method, etc. are generally known. A thermal bond method and a needle punch method, which are easy to design, are preferable.
また、前記前記三次元網目構造のシートの縦幅と横幅の寸法は、必要に応じて任意の寸法とすることができるが、縦幅が好ましくは３．２〜７．０ｍ、さらに好ましくは３．５〜６．０ｍであり、また横幅が好ましく０．５〜１．５ｍ、さらに好ましくは０．８〜１．３ｍである。縦幅が短いと大型車のタイヤの接地面を一様に消毒することができない。例えば、大型貨物自動車のタイヤ外径は、おおよそ１ｍあり、タイヤの接地面１周すべてを消毒するためには円周である少なくとも３．２ｍ以上必要である。また、縦幅が長いと消毒効果が出ているにもかかわらずさらにタイヤの接地面を消毒液に接触させることになり消毒液の無駄となり、また未使用時の保管スペースを徒に必要とするので、消毒を確実に行うためにタイヤの接地面を２周消毒液に接触する長さが好ましい。さらに、横幅が狭いとタイヤの接地面を一様に消毒することは困難であり、車輪の片方に２個のタイヤを装着することもある大型車が通行することもあるため０．５ｍ以上が好ましく、一方幅が広すぎるとほとんど通過しない中央部に含浸させた消毒剤が無駄になることもあり、また自転車専用に使用する場合にも同様に消毒剤が無駄となり、さらに不必要に重くなることから使用時の運搬に支障を来すことになるので、一般国道の横幅がおおよそ２．７〜３．３ｍであることから当該消毒マットを二枚並べてもこの範囲に収まるような横幅とすることが好ましい。 In addition, the vertical and horizontal dimensions of the sheet having the three-dimensional network structure can be arbitrarily set as required, but the vertical width is preferably 3.2 to 7.0 m, and more preferably 3 The width is preferably 0.5 to 1.5 m, more preferably 0.8 to 1.3 m. If the vertical width is short, the ground contact surface of the tire of a large vehicle cannot be disinfected uniformly. For example, the outer diameter of a tire of a large lorry is approximately 1 m, and at least 3.2 m, which is a circumference, is necessary to disinfect the entire contact surface of the tire. In addition, if the vertical width is long, the disinfecting effect is exerted, and further, the ground contact surface of the tire is brought into contact with the disinfecting solution, so that the disinfecting solution is wasted and the storage space when not in use is required. Therefore, in order to surely perform sterilization, the length in which the tire contact surface is in contact with the two-round disinfectant is preferable. Furthermore, if the width is narrow, it is difficult to disinfect the ground contact surface of the tire uniformly, and a large vehicle that sometimes has two tires on one side of the wheel may pass through, so that 0.5 m or more On the other hand, if the width is too wide, the disinfectant impregnated in the central portion that hardly passes through may be wasted, and the disinfectant is also wasted when used exclusively for bicycles, and becomes unnecessarily heavy. Therefore, the width of the general national highway is approximately 2.7 to 3.3m, so the width should be within this range even if two disinfecting mats are arranged side by side. It is preferable.
また、前記三次元網目構造のシートの厚みは、好ましくは６〜２０ｍｍ、さらに好ましくは１０〜１５ｍｍである。前記三次元網目構造のシートの厚みが薄すぎると消毒液を十分に含浸することができない。一方で、前記三次元網目構造のシートが厚過ぎると製造時間が長くなり生産性に劣る。 The thickness of the sheet having the three-dimensional network structure is preferably 6 to 20 mm, and more preferably 10 to 15 mm. If the sheet having the three-dimensional network structure is too thin, the disinfectant cannot be sufficiently impregnated. On the other hand, if the sheet having the three-dimensional network structure is too thick, the production time becomes long and the productivity is poor.
また、本発明の車両消毒用マットの使用時に当該マットの識別性を高めるため、又は汚れを目立たなくするために、前記三次元網目構造のシートの製造時に顔料を添加したり着色された繊維を用いたりするなどして、任意の色彩に着色することや模様を付することができる。 Further, in order to enhance the discriminability of the mat when the vehicle disinfection mat of the present invention is used, or to make the stain inconspicuous, pigments added or colored fibers are used during the production of the sheet having the three-dimensional network structure. For example, it can be used to add any color or pattern.
また、本発明の車両消毒用マットは必要に応じて２枚以上重ねて使用することもできる。車両消毒用マットに消毒液を追加する頻度を少なくしたい等の諸事情に対応することができる。 In addition, two or more of the vehicle disinfection mats of the present invention can be used as necessary. It is possible to cope with various situations such as reducing the frequency of adding the disinfectant to the vehicle disinfection mat.
本発明に使用される疎水性フィルムは、車両消毒用マットに消毒液を供給して使用する際に、前記三次元網目構造のシートの少なくとも一面を覆い消毒液の漏れを防ぐために使用される水分を透過しにくいフィルムである。このように前記疎水性フィルムを用いることにより、本発明の車両消毒用マット使用時に車両のタイヤの接地面に接する面と反対側の面及び側面に消毒液が押し出されにくくなり、消毒液の追加頻度を低減することができる。 The hydrophobic film used in the present invention is a moisture film used for covering at least one surface of the sheet having the three-dimensional network structure and preventing leakage of the disinfectant when the disinfectant is supplied to the vehicle disinfecting mat. It is a film that is difficult to transmit. By using the hydrophobic film as described above, when the vehicle disinfection mat of the present invention is used, it becomes difficult for the disinfectant to be pushed out to the surface and the side opposite to the surface in contact with the ground contact surface of the vehicle tire. The frequency can be reduced.
疎水性フィルムに用いられる素材は、ＰＥＴ樹脂、ポリプロピレン樹脂、ポリエチレン樹脂などの合成樹脂が用いられる。車両用足踏み消毒マットの保存管理又は運搬を簡便にするために、前記疎水性フィルムの厚さは、５０〜３００μｍが好ましい。 The material used for the hydrophobic film is a synthetic resin such as PET resin, polypropylene resin, or polyethylene resin. In order to simplify the storage management or transportation of the vehicle foot disinfection mat, the thickness of the hydrophobic film is preferably 50 to 300 μm.
疎水性フィルムは、前記三次元網目構造のシートと、熱による疎水性フィルムの融着により、接着剤により、少なくとも底面と側面を覆うように固定することにより又はゴムを当該フィルムの淵に任意の方法で固定することにより、一体となる構造として使用することが好ましい。 The hydrophobic film is formed by fixing the sheet of the three-dimensional network structure and the hydrophobic film by heat, fixing it with an adhesive so as to cover at least the bottom surface and the side surface, or attaching rubber to the edge of the film. It is preferable to use as a unitary structure by fixing by a method.
また、前記三次元網目構造のシートに含浸させた消毒液を外部に漏洩させないようするために、車両のタイヤの接地面と接触する面以外の面、すなわち側面と底面の表面を、加熱して溶融することにより網目構造を封じ消毒剤を透過させなくする加工、ポリエチレン、ポリウレタン、シリコン、ゴム、テフロン（登録商標）などの高分子材料を塗布又は吹き付けることにより網目構造を封じ消毒剤を透過させなくする加工を行うことも好ましい。 Further, in order to prevent the disinfectant impregnated in the sheet having the three-dimensional network structure from leaking to the outside, the surface other than the surface that contacts the ground contact surface of the vehicle tire, that is, the surface of the side surface and the bottom surface is heated. Processing that seals the network structure by melting and prevents the disinfectant from permeating, and coating or spraying polymer materials such as polyethylene, polyurethane, silicone, rubber, Teflon (registered trademark) to allow the disinfectant to permeate the network structure It is also preferable to perform the process of eliminating.
車両のタイヤの接地面を消毒するために本発明の車両用消毒用マットに含浸させる消毒剤は、塩基性又は酸性などの消毒性に優れる水溶液のいずれのものでもよく、塩基性水溶液であればｐＨが９〜１２が好ましく、酸性水溶液であればｐＨが１〜３が好ましい。 The disinfectant impregnated in the vehicle disinfection mat of the present invention in order to disinfect the contact surface of the vehicle tire may be any of basic or acidic aqueous solutions excellent in disinfection, and any basic aqueous solution may be used. The pH is preferably 9 to 12, and the pH is preferably 1 to 3 if it is an acidic aqueous solution.

Hydrogen carbonate such as potassium hydrogen can be used alone or in combination by diluting with water. Moreover, those aqueous solutions marketed or those aqueous solutions can be diluted and used.
また、酸性水溶液を作成するための酸性化合物としては、塩酸、硫酸、硝酸などの強酸、酢酸、ギ酸、クエン酸などの弱酸などが単体又はそれらを組み合わせて、液状物は原液又は水で希釈して、気体又は固形物は水に溶解させて使用することにより使用することができる。また、市販されているそれらの水溶液又はその水溶液を希釈して使用することができる。 As acidic compounds for preparing acidic aqueous solutions, strong acids such as hydrochloric acid, sulfuric acid, and nitric acid, weak acids such as acetic acid, formic acid, and citric acid are used alone or in combination, and the liquid is diluted with the stock solution or water.

上記の目付３０００ｇ／ｍ２の不織布を、１００ｍｍ角の正方形に裁断して、乾燥重量（ｇ）を測定し、約２００ｍｌの蒸留水を入れた直径１５ｃｍの大型シャーレの中に、約５分間浸漬させ蒸留水を十分吸収させた。その後、含水した不織布を取り出し、その重量（ｇ）を測定した。そして、上記の裁断された不織布の含水重量（ｇ）から乾燥重量（ｇ）を差し引き、１ｍ２当たりの重量に換算した値を飽和含水量（Ｌ／ｍ２）とした。その結果を表１に示す。このことから、消毒液の補充頻度が少なくて済むことがわかる。
<Saturated water content test>
The nonwoven fabric with a basis weight of 3000 g / m 2 is cut into a square of 100 mm square, the dry weight (g) is measured, and immersed in a large petri dish with a diameter of 15 cm containing about 200 ml of distilled water for about 5 minutes. The distilled water was sufficiently absorbed. Then, the nonwoven fabric containing water was taken out and the weight (g) was measured. And the dry weight (g) was subtracted from the moisture content (g) of the above-mentioned cut nonwoven fabric, and the value converted into the weight per 1 m 2 was defined as the saturated moisture content (L / m 2 ). The results are shown in Table 1. From this, it can be seen that the replenishment frequency of the disinfectant solution can be reduced.
＜耐薬品性試験＞
耐薬品性試験を、ＪＩＳ Ｌ１０３０「繊維製品の混用率試験方法」を準用して行った。すわなち、各薬液を５０~１００ｍｌに調整して、ガラス製又は耐薬品性容器に入れ、これに目付３０００ｇ／ｍ２の不織布の小片を浸した。その後、十分に薬液と接触させた後、前記小片の溶解の有無を目視にて確認した。なお、用いた薬液としては、強酸として濃硫酸、濃硝酸、３５％塩酸を、強塩基として５％水酸化ナトリウム水溶液（煮沸条件下で浸漬）を、弱酸として５％クエン酸水溶液（煮沸条件下で浸漬）を、弱塩基として８％炭酸ナトリウム水溶液（煮沸条件下で浸漬）を、アルコールとしてエタノール（煮沸条件下で浸漬）を用いた。その結果、いずれの薬液にも溶解せず、消毒マットとして使用しうるものである。
<Chemical resistance test>
The chemical resistance test was carried out by applying JIS L1030 “Test method for mixed ratio of textile products”. That is, each chemical solution was adjusted to 50 to 100 ml and placed in a glass or chemical resistant container, and a piece of non-woven fabric having a basis weight of 3000 g / m 2 was immersed therein. Then, after making it fully contact with a chemical | medical solution, the presence or absence of melt | dissolution of the said small piece was confirmed visually. The chemicals used were concentrated sulfuric acid, concentrated nitric acid, 35% hydrochloric acid as strong acid, 5% sodium hydroxide aqueous solution (immersion under boiling conditions) as strong base, and 5% citric acid aqueous solution (in boiling conditions) as weak acid. 8% sodium carbonate aqueous solution (immersion under boiling conditions) was used as the weak base, and ethanol (immersion under boiling conditions) was used as the alcohol. As a result, it does not dissolve in any chemical solution and can be used as a disinfecting mat.
＜表面強度試験＞
表面強度試験を、ＪＩＳ Ｌ１９１３「一般短繊維不織布試験方法」摩耗強さ（テーバ形法）の外観変化の判定に準じて行った。すわなち、不織布用の摩耗輪ＣＳ−１７を用い、１７５０ｋｇｆの荷重を掛け、回転回数１０００回転処理、２０００回転処理及び４０００回転処理後の目付３０００／ｍ２の不織布の表面の変化を観察した。その結果を表２に示す。このことから、処理回数を増やしても４級と高い級数で維持されており、外観上の変化が特になく、実使用上十分な耐久性を有することがわかる。
