Abstract
Description
本発明は、土木用途、ＦＲＰ用途に応用可能な補強不織布に閧するものである。また、土木用途、ＦＲＰ用途以外にも、自動車用途、建材用途、衣料用途、家電用途などの補強を必要とする用途に使用することが可能である。 The present invention relates to a reinforced nonwoven fabric applicable to civil engineering applications and FRP applications. In addition to civil engineering applications and FRP applications, the present invention can be used for applications that require reinforcement, such as automotive applications, building material applications, clothing applications, and home appliance applications.
不織布を補強する方法としては、不織布にネット等を張り合わせる方法や、不織布自体に糸等を編み込む方法が、知られている。また、不織布間に補強糸を挿入してニードルパンチで複合する方法も知られている。
しかしながら、従来技術には次のような問題点があった。
（１）不織布表面に、ネットや補強糸を複合した場合、ネットや補強糸の剥離が発生しやすい。
（２）二種類以上のシートを張り合わせるため、最低でも二工程以上を有し、また二種類以上の材料が要求されるため、生産費用が高くなるとの問題があった。However, the prior art has the following problems.
(1) When a net or reinforcing yarn is combined on the nonwoven fabric surface, the net or reinforcing yarn is easily peeled off.
(2) Since two or more types of sheets are bonded together, there is a problem that at least two steps or more are required, and two or more types of materials are required, resulting in high production costs.
第１のカードから得られるウエブと第２のカードから得られるウエブの層間に連続する補強糸を挿入して一体化する製造方法で、補強糸の強力を損なうことなく、補強不織布を得ることができる。 In a manufacturing method in which a continuous reinforcing yarn is inserted between the web obtained from the first card and the web obtained from the second card and integrated, a reinforcing nonwoven fabric can be obtained without impairing the strength of the reinforcing yarn. it can.
不織布製造工程に一貫化されることにより、生産性の向上、工程の簡略化、コストの低減が得られる。 By being integrated into the nonwoven fabric manufacturing process, productivity can be improved, the process can be simplified, and costs can be reduced.
本願発明の補強不織布の製造方法は前記の通り、２台のカードから得られる各々のウエブの層間に補強糸を挿入して一体化させたことで、巻き取り方向の強力を向上させた、補強不織布である。 As described above, the method for producing a reinforced nonwoven fabric of the present invention is a reinforcement in which the strength in the winding direction is improved by inserting and integrating the reinforcing yarns between the layers of the webs obtained from the two cards. It is a nonwoven fabric.
前記、補強糸の形状は紡績糸、マルチフィラメント、モノフィラメント等の連続した繊維状であれば良く、目的に応じて選択することが出来る。また、補強糸の材質は、ポリエステル、ポリカーボネート、ポリエチレン、ポリプロピレン、ナイロン、ビニロン、レーヨンなどの合成繊維や、綿、麻、絹などの天然繊維や、これらの複数の材質を複合した繊維を使用することができる。 The shape of the reinforcing yarn may be a continuous fiber such as spun yarn, multifilament, monofilament, and can be selected according to the purpose. In addition, the material of the reinforcing yarn uses synthetic fibers such as polyester, polycarbonate, polyethylene, polypropylene, nylon, vinylon, rayon, natural fibers such as cotton, hemp, silk, and fibers that are a combination of these materials. be able to.
また、前記２台のカードから得られる各々のウエブに特に制限はなく、既知の不織布製造工程で得られるウエブであり、また、２台のカードから得られる各々のウエブの、繊維構成、重量、厚み、形状は同一でなくても良い。 Moreover, there is no restriction | limiting in particular in each web obtained from the said 2 card | curd, It is a web obtained by the known nonwoven fabric manufacturing process, Moreover, the fiber structure of each web obtained from 2 card | curds, weight, The thickness and shape may not be the same.
不織布自体と補強糸を接着する方法として、ケミカルボンド法や、サーマルボンド法が望ましい。ニードルパンチ法では、補強糸を傷つけるため、補強糸の強力低下や糸切れが発生することが考えられ、適切ではない。 As a method for bonding the nonwoven fabric itself and the reinforcing yarn, a chemical bond method or a thermal bond method is desirable. The needle punch method is not appropriate because the reinforcing yarn is damaged, and the strength of the reinforcing yarn may be reduced or the yarn may be broken.
ケミカルボンド法は、アクリル系、エポキシ系、合成ゴム系などの接着剤溶液をスプレー加工、含浸加工、コーティング加工などの工程によりシートを接着する方法が取られる。 The chemical bond method is a method in which an adhesive solution such as an acrylic type, an epoxy type, or a synthetic rubber type is adhered to the sheet by a process such as spray processing, impregnation processing, or coating processing.
サーマルボンド法では、ウエブや補強糸に熱融着する繊維を混入させて、熱風や加熱ロールなどで熱融着成分を融解させてウエブや補強糸を接着させる方法が取られる。 In the thermal bond method, a method is adopted in which fibers to be thermally fused are mixed into the web or the reinforcing yarn, and the thermal fusion component is melted with hot air or a heating roll to adhere the web or the reinforcing yarn.
本発明を図及び実施例により説明する。図１は、発明に基づく実施例に用いたケミカルボンド不織布の製造工程の概略図である。図２は、発明に基づく実施例に用いたサーマルボンド不織布の製造工程の概略図である。 The present invention will be described with reference to the drawings and examples. FIG. 1 is a schematic view of a production process of a chemically bonded nonwoven fabric used in an example based on the invention. FIG. 2 is a schematic diagram of the manufacturing process of the thermal bond nonwoven fabric used in the examples based on the invention.
次の繊維構成でケミカルボンド法の補強不織布を作成した。

この不織布の強力をＪＩＳ Ｌ １０９６（補強糸２本を含む試料 ５０ｍｍ巾 チャク間 １００ｍｍ 引張スピード ３００ｍｍ／分）で測定したところ、２５３Ｎであった。A reinforced nonwoven fabric of chemical bond method was prepared with the following fiber configuration.
Polyester fibers (fineness = 6.6 decitex) are spun from the first card at a parallel web of 100% by weight and a weight of 30 g / m 2 . Polyester multifilament (1100 dtex 192 filament) provided by creel on the web spun from the first card is inserted as a reinforcing yarn at 25 mm intervals in the width direction, and the same as the first card from the second card Polyester fiber (fineness = 6.6 dtex) 100% by weight Weight 30 g / m 2 A parallel web is spun, and the web spun from the first card is laid on the reinforcing yarn. This is conveyed by a conveyor, impregnated in a binder (acrylic emulsion concentration 30%) in an impregnation tank, squeezed with a squeeze roll so that the solid content is 20 g / m 2 , and then dried in a dryer. And take up with a take-up device. The obtained nonwoven fabric obtained a chemical bond nonwoven fabric in which reinforcing yarns were combined at 25 mm intervals with a weight of 83 g / m 2 and a thickness of 0.5 mm.
The strength of this non-woven fabric was measured by JIS L 1096 (sample including two reinforcing yarns, 50 mm wide, between chucks, 100 mm, tensile speed 300 mm / min) and found to be 253N.
（比較例１）
補強糸を挿入しないこと以外は実施例１と全く同様に加工して、ケミカルボンド不織布を得た。この不織布の強力を測定したところ、１３５Ｎであった。(Comparative Example 1)
A chemically bonded nonwoven fabric was obtained in the same manner as in Example 1 except that no reinforcing yarn was inserted. The strength of this nonwoven fabric was measured and found to be 135N.
第一のカードよりレギュラーポリエステル繊維（繊度＝６．６デシテックス）５０重量％、芯鞘型のポリエステル熱融着繊維（鞘部＝融点１１０℃、繊度＝６．６デシッテクス）５０質量％の重量 ５０ｇ／ｍ２のパラレルウエブを紡出する。第一のカードから紡出したウエブ上にクリールより提供されるポリエステル マルチフィラメント（１１００デシテックス １９２フィラメント）１０本を合糸して補強糸として幅方向 ５０ｍｍ間隔に挿入する。第二のカードからはポリエステル繊維（繊度＝１７デシテックス）３０重量％ 熱融着繊維（鞘部＝融点１１０℃、繊度＝２２デシッテクス）４０重量％ ４０ｇ／ｍ２のパラレルウエブを紡出して、第一のカードから紡出したウエブと補強糸の上に重ねる。これを、コンベアでドライヤーに搬送して１５０℃の熱風でポリエステル熱融着の融着部分を溶融させて、繊維と補強糸を一体化させたサーマルボンド不織布を得た。
この不織布の強力をＪＩＳ Ｌ １０９６（補強糸１本を含む試料 ５０ｍｍ巾 チャク間 １００ｍｍ 引張スピード ３００ｍｍ／分）で測定したところ、４５３Ｎであった。50% by weight of regular polyester fiber (fineness = 6.6 dtex) from the first card, 50% by weight of 50% by weight of core-sheath type polyester heat-sealing fiber (sheath part = melting point 110 ° C., fineness = 6.6 dtex) / m to spinning a parallel web 2. Ten polyester multifilaments (1100 dtex 192 filaments) provided by the creel are combined on the web spun from the first card and inserted as reinforcing yarns at intervals of 50 mm in the width direction. From the second card, a polyester fiber (fineness = 17 dtex) is 30% by weight, a heat-sealing fiber (sheath portion = melting point 110 ° C., fineness = 22 dtex) is 40% by weight, and a parallel web of 40 g / m 2 is spun. It is layered on the web spun from one card and the reinforcing yarn. This was conveyed to a dryer by a conveyer, and the fused portion of the polyester heat fusion was melted with hot air at 150 ° C. to obtain a thermal bond nonwoven fabric in which the fibers and the reinforcing yarn were integrated.
It was 453N when the strength of this nonwoven fabric was measured by JIS L 1096 (sample including one reinforcing yarn 50 mm wide, between chucks 100 mm, tensile speed 300 mm / min).
（比較例２）
補強糸を挿入しないこと以外は実施例２と全く同様に加工して、サーマルボンド不織布を得た。この不織布の強力を測定したところ、１３５Ｎであった。(Comparative Example 2)
A thermal bond nonwoven fabric was obtained in the same manner as in Example 2 except that the reinforcing yarn was not inserted. The strength of this nonwoven fabric was measured and found to be 135N.
本発明は、木用途、ＦＲＰ用等の補強不織布に用いられ、強力が向上されるように加工されたものであるが、その製造方法が不織布生産に連結一貫し、且つ、工程が簡略化される点において産業上の利用の可能性を有する。 The present invention is used for reinforcing non-woven fabrics for wood use, FRP, etc., and has been processed to improve strength, but its manufacturing method is consistently linked to non-woven fabric production, and the process is simplified.
