(57) [Summary] [Purpose] To provide a sandbag that has excellent durability and does not run out of sediment. [Constitution] A sandbag is made using a long-fiber non-woven fabric.
Description
【０００１】[0001]
本考案は、耐久性に優れ目開きによる破損の少ない長繊維不織布に関する。 The present invention relates to a long-fiber non-woven fabric having excellent durability and less damage due to opening.
【０００２】[0002]
従来、災害時に主として使用される土のう袋は、ポリプロピレン製又はポリエ チレン製のスリットヤーン（細幅テープ）で織成された織物で製造されていた。 例えば、図４は現在用いられているスリットヤーン製の織物からなる土のう袋 を示す。この土のう袋は、底が８の所で、側部が７の所で縫着されており、上部 ９がひも６でしぼってとじられるようになっている。 Conventionally, sandbags, which are mainly used in the event of a disaster, have been manufactured with a woven fabric made of polypropylene or polyethylene slit yarn (thin tape). For example, FIG. 4 shows a sandbag made of slit yarn, which is currently used. This sandbag is sewn at the bottom at 8 and at the side at 7, and the upper part 9 is squeezed and bound by the string 6.
【０００３】 しかしながら、この土のう袋は、織物製であるため、目開きし、内部の土砂な ど充填物が流出し、耐久性に乏しく、また流出物によって公害問題が発生する欠 点を有していた。[0003] However, since this sandbag is made of a woven fabric, it has openings, and fillers such as earth and sand inside flow out, resulting in poor durability, and there is a point that pollution problems occur due to the outflow. Was there.
【０００４】[0004]
このように、現在のポリエチレン製又はポリプロピレン製織物の土のう袋では 、災害対策工事中の積上げ作業中、作業後に目開きによる破損、内部の土砂の流 出が多く、地域住民からの苦情の源となるものであつた。 本考案は、従来の土のう袋の欠点を解消し、叙上の問題のない土砂流出なく、 破損の少ない耐久性のある土のう袋を提供することを課題とする。 As described above, the current polyethylene sandbags made of polyethylene or polypropylene have many damages due to openings during the stacking work during the disaster prevention work, and the outflow of the internal sand and sand, which is a source of complaints from local residents. It was. It is an object of the present invention to solve the drawbacks of the conventional sandbags and to provide a durable sandbag that is free from the problem of sediment and has no damage.
【０００５】[0005]
本考案は、かかる課題を解決するために、次の手段をとるものである。すなわ ち、本考案は、長繊維不織布からなる土のう袋であり、また、目付３０〜１５０ ｇ／ｍ2 のスパンボンド不織布からなる土のう袋であり、さらにまた、ポリエス テル繊維のスパンボンド不織布の土のう袋である。The present invention takes the following means in order to solve such a problem. That is, the present invention is a sandbag bag made of long-fiber nonwoven fabric, and a sandbag bag made of spunbonded nonwoven fabric having a basis weight of 30 to 150 g / m 2 , and also a spunbonded nonwoven fabric made of polyester fiber. It is a sandbag.
【０００６】 以下に本考案を図をまじえながら詳細に説明する。なお、図は、あくまでも説 明のためのものであって、本考案の趣旨に沿う限り変更は許容される。The present invention will be described in detail below with reference to the drawings. It should be noted that the drawings are for the purpose of explanation only, and modifications are permissible as long as the spirit of the present invention is met.
【０００７】 本考案の土のう袋は長繊維不織布からなる。長繊維不織布は、強度的に方向性 が少ないこと且つ目開きがないこと、さらに嵩ばらないことから採用されるもの である。長繊維不織布としてはスパンボンド不織布が好ましい。The sandbag of the present invention is made of long-fiber non-woven fabric. The long-fiber nonwoven fabric is adopted because it has little directionality in strength, has no openings, and is not bulky. A spunbonded nonwoven fabric is preferable as the long fiber nonwoven fabric.
【０００８】 該長繊維不織布は、長繊維を重ねて接着されてなるものであるが、この接着方 法としては、ニードルパンチによる交絡法、水流交絡法、融着繊維を混入したサ ーマルボンド法、樹脂を含浸させるレジンボンド法、ロールによる熱圧着法が挙 げられる。そのうちでも、コスト及び保管時に嵩ばらない点からエンボスロール による熱圧着法が好ましい。図１は、エンボスロールによって熱圧着したスパン ボンド不織布１の例を示す。The long-fiber non-woven fabric is formed by laminating long fibers and adhering them. As the adhering method, there are a entanglement method using a needle punch, a hydroentanglement method, a thermal bond method in which fusible fibers are mixed, The resin bond method in which a resin is impregnated and the thermocompression method using a roll are listed. Of these, the thermocompression bonding method using an embossing roll is preferable from the viewpoint of cost and not being bulky during storage. FIG. 1 shows an example of a spunbonded nonwoven fabric 1 thermocompression bonded by an embossing roll.
【０００９】 前記長繊維不織布の素材としては、ポリプロピレン、ポリエチレン、ポリエチ レンテレフタレート、ポリブチレンテレフタレート、ポリアミドなどの各種繊維 があげられる。このうちでもポリエチレンテレフタレート、ポリブチレンテレフ タレートなどのポリエステルが土のう袋の強さを高める上で好ましい。太さは、 ２〜１５ｄが好ましい。Examples of the material of the long fiber non-woven fabric include various fibers such as polypropylene, polyethylene, polyethylene terephthalate, polybutylene terephthalate and polyamide. Of these, polyesters such as polyethylene terephthalate and polybutylene terephthalate are preferred for increasing the strength of the sandbag. The thickness is preferably 2 to 15d.
【００１０】 長繊維不織布の目付は３０ｇ／ｍ2〜１５０ｇ／ｍ2 が好ましい。３０ｇ／ｍ2 未満になると、薄くなりすぎて強度的に問題が起こりやすく、他方１５０ｇ／ｍ 2 をこえると嵩ばりやすく好ましくない。かかる観点から４０〜１２０ｇ／ｍ2 がさらに好ましい。The basis weight of the long fiber non-woven fabric is 30 g / m2~ 150g / m2 Is preferred. 30 g / m2 If it is less than 100 g, it becomes too thin and a problem in strength tends to occur. 2 If it exceeds, it tends to be bulky, which is not preferable. From this viewpoint, 40 to 120 g / m2 Is more preferable.
【００１１】 図２は、長繊維不織布からなる土のう袋を示す。土のう袋の上部には、土砂の 流出を防ぎ、運搬に便利な様にひも４を通す場所４′が設けられている。側部３ 、下部２は接合されており、接合の手段としては、ミシン縫製、超音波ウェルダ ー、高周波ウェルダー、シーラーなどがあげられる。図３は、接合の一例を示す もので、端部５′、５″を重ねて縫製部５で叙上の接合手段で縫製されたもので ある。このように端部５′、５″を重ねて内側に折り返し、接合したものは、接 合端部の強度が向上し、この部位からの土砂流出防止に効果的である。FIG. 2 shows a sandbag made of long-fiber nonwoven fabric. At the upper part of the sandbag, there is provided a place 4'for preventing the outflow of soil and passing the cord 4 for convenient transportation. The side portion 3 and the lower portion 2 are joined together, and means for joining are sewing machine sewing, ultrasonic welder, high-frequency welder, sealer and the like. FIG. 3 shows an example of joining, in which the end portions 5 ′ and 5 ″ are overlapped and sewn by the above-mentioned joining means at the sewing portion 5. Thus, the end portions 5 ′ and 5 ″ are joined. The one that is overlapped and folded inward and joined has the strength of the joint end improved and is effective in preventing the outflow of sediment from this part.

実施例 １ ポリエチレンテレフタレート３ｄの表１に示すような物性を有するスパンボン ド不織布をエンボスローラ（図１に示す模様）によってエンボス加工した熱圧着 品（目付７０ｇ／ｍ2 ）を図２に示すように折り曲げ、側部３、下部２をミシン で縫製して側部の長さ６０ｍ×下部の長さ４８ｍの大きさの土のう袋を作り、比 較のための同じ大きさの現行品（ポリプロピレン製織物、ポリエチレン製織物） とともに落下テストによる強度試験を行ない、表２にその結果を示した。Example 1 As shown in FIG. 2, a thermocompression-bonded product (weight per unit area: 70 g / m 2 ) obtained by embossing a spunbonded nonwoven fabric having the physical properties shown in Table 1 of polyethylene terephthalate 3d with an embossing roller (pattern shown in FIG. 1) is shown. Bending and sewn the side part 3 and the lower part 2 with a sewing machine to make a sandbag measuring 60 m on the side and 48 m on the lower part. , A polyethylene woven fabric) were subjected to a strength test by a drop test, and the results are shown in Table 2.

【表１】 [Table 1]
【００１４】[0014]
【表２】 [Table 2]
【００１５】 表１から、本考案の土のう袋は、現行品に比して粒調砕石、砂のいずれの場合 にあっても耐久性がすぐれていることがわかった。また、現行品は、縫製部分か ら簡単に破損し、また、目付が大きく重量の点で運搬作業上不利であった。From Table 1, it was found that the sandbags of the present invention have superior durability compared with the current products in both cases of crushed stone and sand. In addition, the current product was easily damaged from the sewn part and had a large basis weight, which was disadvantageous in terms of transportation work due to its weight.
【００１６】[0016]
本考案の土のう袋は、保管時にも嵩ばらず、作業中の衝撃および長時間の放置 にも耐え、土砂流出、破損の少ない、耐久性のあるものである。 The sandbag of the present invention is not bulky during storage, can withstand shock during work and is left for a long time, has little sediment outflow and damage, and is durable.
