Description
本発明は連続的に製造する裏面補強した不織布製品に関する。 The present invention relates to a continuously reinforced non-woven fabric product.
従来の不織布の製造は、多層に重ねた、多数のパイル繊維を所定幅にニ−ドルで打ち込んで互いに繊維を絡み合わせて、布状に形成されていた。（参考文献 特願２００５−７１８６７ 明細書［背景技術］［０００３］［０００４］［０００５］並びに［図５］）しかして、そのニ−ドルを最終の製品化に必要な形状形成に作動さして、製品化に不必要な部分には、作動させないことによって、製品化効率を向上させた。 In the production of a conventional nonwoven fabric, a plurality of pile fibers stacked in multiple layers are driven into a predetermined width with a needle, and the fibers are entangled with each other to form a cloth. (Reference Japanese Patent Application No. 2005-71867 [Background Art] [0003] [0004] [0005] and [FIG. 5]) However, the needle is operated to form a shape necessary for final productization, Product efficiency is improved by not operating parts that are not necessary for commercialization.
しかして、製品化のためには、立体成形や製品としての必要な剛性を付与するために不織布裏面にパイル繊維と熱溶着するバッキング材或いは溶着シ−トを熱溶着させる必要がある。そのために、不織布繊維を熱可塑牲樹脂とし、それを熱溶着する同質材の溶融状態の粉状或いは粒状体を裏面に吹き付けるか、溶融シ−トを不織布裏面に貼る作業が必要である。 Therefore, for commercialization, it is necessary to thermally weld a backing material or a welding sheet that is thermally welded to the pile fiber on the back surface of the nonwoven fabric in order to provide three-dimensional molding or necessary rigidity as a product. For this purpose, it is necessary to use a nonwoven fabric fiber as a thermoplastic resin and to spray a molten powdery or granular material of a homogeneous material on which it is thermally welded onto the back surface, or to apply a molten sheet to the back surface of the nonwoven fabric.
それには、その裏面補強作業が必要であるが、従来は、一製品ごとに、その作業をしていたので、非効率な作業であった。 In order to do so, it is necessary to reinforce the back surface. Conventionally, the work has been performed for each product, which is an inefficient operation.
不織布による立体的な加熱成形製品化のため或いは平面的不織布製品に剛性を付与するための裏面補強材の貼布が必要である。 It is necessary to apply a back surface reinforcing material to make a three-dimensional thermoformed product using a nonwoven fabric or to give rigidity to a planar nonwoven fabric product.
その複数の製品化に必要とする部分の裏面補強作業を連続的に実施することが生産技術的には必要である。 In terms of production technology, it is necessary to continuously perform the back surface reinforcement work for the parts required for the commercialization of the products.
製品化形状のみにニ−ドルを打ち込むように、ＮＣ装置等を駆動させると共に、製品化部分を連結状に繋ぐ形状部分にもＮＣ装置を駆動させるようにセッティングする。その連結形状は、製品化部分の繊維重量を連続的に移動させるに足りる大きさと強さが必要である。 The NC device or the like is driven so that the needle is driven only into the productized shape, and the NC device is also driven so as to drive the shape portion that connects the productized portions in a connected manner. The connecting shape needs to have a size and strength sufficient to continuously move the fiber weight of the commercialized part.
連結部の不織布形成後、裏面の補強工程に連続して導入するのがベタ−であるが、それが出来ないときは、不織布を巻き物状にして裏面補強工程に送付することもある。
その場合、製品部を続けて巻き取れる大きさと重量の連結部が必要である。After forming the non-woven fabric of the connecting portion, it is solid to continuously introduce it into the back surface reinforcing step, but when it is not possible, the non-woven fabric may be wound up and sent to the back surface reinforcing step.
In that case, a connecting portion having a size and a weight that can continuously wind up the product portion is required.
裏面補強工程では、熱可塑性樹脂製の不織布繊維と互いに熱溶着する溶融状態のパウダ−や粒子或いはシ−トで不織布繊維の裏面の製品化に必要な部分に溶着させて不織布を補強する。又それが加熱立体成形にも必要となる。 In the back surface reinforcing step, the nonwoven fabric is reinforced by welding it to a portion necessary for commercialization of the back surface of the nonwoven fabric fiber with a melted powder, particles or sheet that are thermally welded to the nonwoven fabric fiber made of thermoplastic resin. It is also necessary for three-dimensional heating.
次工程で必要形状に裁断したり、プレス成形型などで立体成形して必要形状に裁断し、取り付け部品等を取り付ける。 In the next process, it is cut into the required shape, or three-dimensionally molded with a press mold or the like, and cut into the required shape, and attached parts and the like are attached.
裁断後の不要端材は、リサイクル工程に回送する。 Unused scrap after cutting is sent to the recycling process.
不織布をその製品化に必要とする部分にのみにその繊維を使用するから、従来の一定の幅で不織布形成する場合と比較して遥かに繊維の節減とその作業時間を軽減する。 Since the fibers are used only in the portions where the nonwoven fabric is required for commercialization, the fiber saving and the working time are greatly reduced as compared with the case of forming the nonwoven fabric with a constant width.
不織布の裏面補強工程における、製品毎の裏面補強作業が無くなり、自動的連続作業が可能となり、生産技術的効率向上となる。 In the non-woven fabric back surface reinforcing process, the back surface reinforcing work for each product is eliminated, and automatic continuous work becomes possible, improving production technical efficiency.
不織布の裏面補強工程が不織布製造工程と連続していない場合に、不織布を巻き物状態にして送付なり、一時保管することが出来る。 When the back surface reinforcing process of the nonwoven fabric is not continuous with the nonwoven fabric manufacturing process, the nonwoven fabric can be sent in a wound state and temporarily stored.
自動車、車両、船舶、飛行機、建造物等の内装部品の材料費や製造費を安くする事が出来る。 Material costs and manufacturing costs for interior parts such as automobiles, vehicles, ships, airplanes and buildings can be reduced.
廃棄する材料を減らすことが出来、産業廃棄物を無くすことが出来る。 Material to be discarded can be reduced, and industrial waste can be eliminated.
図１のごとく、不織布製品１を互いに熱融着する裏面補強シ−ト３により連続して加熱接着して行くため、不織布製品１を不織布製造連結部分２を形成して繋いで製造する。
裏面を補強するシ−ト材質は、不織布繊維材料と熱溶着する、同質の例えばポリプロピレンやポリエチレン、軟質塩化ビニ−ル材等熱可塑性樹脂を利用する。As shown in FIG. 1, since the nonwoven fabric products 1 are continuously heat-bonded by the back surface reinforcing sheet 3 that is heat-sealed to each other, the nonwoven fabric products 1 are formed by connecting the nonwoven fabric production connecting portions 2.
As the sheet material that reinforces the back surface, a thermoplastic resin such as polypropylene, polyethylene, or a soft vinyl chloride material, which is heat-welded with the nonwoven fabric fiber material, is used.
不織布の製品化部分とその連結部分は、その部分のみにニ−ドルが差し込むようにＮＣ装置等自動化装置をプログラムしておく。 An automatic device such as an NC device is programmed so that the needle is inserted into only the non-woven fabric product portion and its connection portion.
実施例はシ−ト形状の裏面補強であるが、不織布材質と同材質の粒状や粉末状樹脂材を加熱軟化させて、不織布裏面に吹き付けても良い。 Although the embodiment is a sheet-shaped back surface reinforcement, a granular or powdered resin material of the same material as the nonwoven material may be heated and softened and sprayed onto the back surface of the nonwoven fabric.
製品は、平面的な形状のみでなく、図２のごとく裏面補強した不織布を裏面加熱軟化して硬質樹脂製等による型によるプレス成形などの方法で立体形状とすることも出来る。 The product is not limited to a planar shape, but can be made into a three-dimensional shape by a method such as press molding with a mold made of a hard resin by softening the back surface of the nonwoven fabric reinforced as shown in FIG.
製品化した後の連結部分や裏面補強の製品化以外部分は切断除去して、再生利用工程に送る。 After the product has been commercialized, the parts other than the commercialization of the backside reinforcement are cut off and sent to the recycling process.
尚裏面を補強する製造工程が連続していない場合に、不織布を巻き物形状にする。 In addition, when the manufacturing process which reinforces a back surface is not continuous, a nonwoven fabric is made into a roll shape.
