Description
本発明は、繊維強化分野における、特に炭素繊維を巻縫いした炭素繊維糸およびその織物に関するものである。 The present invention relates to a carbon fiber yarn in which carbon fibers are wound and particularly a woven fabric thereof in the field of fiber reinforcement.
本出願人は、自動車やモーターボートのボディ等を補強するのに、規格外で廃棄処分される光ファイバーを織物として製織し、有効にリサイクルすることを提案している。 The present applicant has proposed that an optical fiber discarded outside the standard is woven as a woven fabric and effectively recycled to reinforce the body of an automobile or a motor boat.
規格外の廃棄処分される光ファイバーを利用すると、費用は格安となって好ましいが、光ファイバーは滑りやすいので天然や合成の繊維糸と絡ませて織物糸としており、また光ファイバーなので折曲したりすると、途中で切断することがあり、その用途は限定される。 Using non-standard discarded optical fiber is preferable because the cost is cheap, but the optical fiber is slippery, so it is entangled with natural or synthetic fiber yarn, and it is woven yarn. May be cut at a limited time.
また、使用する光ファイバーは、極細状で軽量であるが、多数本を組み合わせると軽量ではなくなってくる。 Moreover, although the optical fiber to be used is very thin and lightweight, when many fibers are combined, it becomes lighter.
一方、軽量で強度が高いことから、炭素繊維の利用が航空機や自動車、ボート、スポーツ分野で行なわれている。たとえば、特開２００３−２０５４２号公報や特開１０−１０２７９２号公報などのように炭素繊維糸を織物や布帛として航空機や構造物の補強用に利用することが提案されている。
しかし、炭素繊維は、単繊維糸径が４〜２０μｍといった極細の繊維長３０〜５００ｍｍといった短繊維と長繊維のものを数十本〜数千本サイジング剤等で付着して炭素繊維糸としているもので、織物とするときに単繊維糸がばらけたり、毛羽だったり、剥がれたりしやすく、また炭素繊維糸を織物としてもその厚さが薄いので何枚も重ね合わせなければならざず、その重ね合わせるのにプリプレグ工程等が必要となったりして相当の手間がかかるものであった。 However, carbon fibers are made of carbon fiber yarns by attaching tens of to thousands of sizing agents or the like with short fibers and long fibers such as ultrafine fibers having a single fiber yarn diameter of 4 to 20 μm and lengths of 30 to 500 mm. In the case of woven fabrics, single fiber yarns are scattered, fluffy, and easy to peel off, and carbon fiber yarns are also thin as woven fabrics, so many sheets must be stacked, In order to superimpose it, a prepreg process or the like is required, which requires considerable labor.
そのため、炭素繊維糸にカバリング精紡機でカバリングすることも提案されているが、一本一本の炭素繊維糸にカバリングするもので、装置も大掛かりとなり、手間もかかり、またそのカバリングが伸縮しやすいもので品質が安定しにくいものであった。 For this reason, it is also proposed to cover carbon fiber yarns with a spinning spinning machine, but it is also possible to cover each carbon fiber yarn, which requires a large amount of equipment and labor, and the covering is easy to expand and contract. The quality was difficult to stabilize.
本発明は、上記のような点に鑑みたもので、上記の課題を解決するために、マルチフィラメントを束ねた炭素繊維束の１束ないし複数束に合成繊維糸の掛合糸を巻縫い掛合して炭素繊維束糸を形成したことを特徴とする巻縫いした炭素繊維糸を提供するにある。 The present invention has been made in view of the above points, and in order to solve the above-mentioned problems, a synthetic fiber yarn is wound on one or more bundles of carbon fiber bundles in which multifilaments are bundled. It is another object of the present invention to provide a wound carbon fiber yarn characterized by forming a carbon fiber bundle yarn.
また、マルチフィラメントを束ねた炭素繊維束の複数束を断面が３芯状や７芯状の多芯ロープ状に束ねた状態として、ポリエチレンやアラミド等の合成繊維糸の掛合糸を巻縫い掛合して、多芯ロープ状の炭素繊維束糸を形成したことを特徴とする巻縫いした炭素繊維糸を提供するにある。 In addition, a plurality of bundles of carbon fiber bundles in which multifilaments are bundled are bundled into a multi-core rope shape having a three-core or seven-core cross section, and a synthetic fiber yarn such as polyethylene or aramid is sewed and wound. Another object of the present invention is to provide a wound carbon fiber yarn characterized by forming a multifilament rope-like carbon fiber bundle yarn.
さらに、マルチフィラメントを束ねた炭素繊維束の１束ないし複数束にロックミシンのメローミシンで２〜５ｍｍのピッチで合成繊維糸の掛合糸を巻縫い掛合して炭素繊維束糸を形成したものである巻縫いした炭素繊維糸を提供するにある。 Further, a carbon fiber bundle yarn is formed by winding a synthetic fiber yarn with a mellow sewing machine of a lock sewing machine at a pitch of 2 to 5 mm and winding it on one or a plurality of bundles of carbon fiber bundles in which multifilaments are bundled. It is in providing a carbon fiber thread that has been wound and sewn.
さらにまた、巻縫いした炭素繊維束糸を経糸および／または緯糸として所定の大きさの織物に形成したことを特徴とする巻縫いした炭素繊維糸による織物を提供するにある。 Furthermore, another object of the present invention is to provide a woven fabric of carbon fiber yarns that are wound and sewn, wherein the carbon fiber bundle yarns that are sewn are formed into a woven fabric of a predetermined size as warps and / or wefts.
またさらに、巻縫いした炭素繊維糸による織物を複数層重ね合わせて補強用材として使用する巻縫いした炭素繊維糸による織物を提供するにある。 Still another object of the present invention is to provide a woven fabric made of wound carbon fiber yarn that is used as a reinforcing material by superposing a plurality of layers of woven fabric made of wound carbon fiber yarn.
本発明の巻縫いした炭素繊維糸およびその織物は、マルチフィラメントを束ねた炭素繊維束の１束ないし複数束に合成繊維糸の掛合糸を巻縫い掛合して炭素繊維束糸を形成することによって、マルチフィラメントを束ねた炭素繊維束の１束ないし複数束を掛合糸で巻縫いでき、単繊維がばらけたり、毛羽立って、剥がれたりせず、かつ炭素繊維束に弾力性を付与できて織物に製織することができるとともに、マルチフィラメントを束ねた炭素繊維束の１束ないし複数束であっても、撚りがかからずに簡単に巻縫いできて分厚く製織することができる。そのため、被補強物に補強する場合に従来に比して少ない積層で補強でき、補強の手間を低減できて補強できる。 The wound carbon fiber yarn of the present invention and the woven fabric thereof are formed by winding a synthetic fiber yarn on one or more bundles of carbon fiber bundles in which multifilaments are bundled to form a carbon fiber bundle yarn. , One or more bundles of carbon fiber bundles bundled with multifilaments can be wound with hooking yarn, single fibers can not be scattered, fluffed, peeled off, and the carbon fiber bundles can be made elastic and woven In addition, even a single bundle or a plurality of bundles of carbon fiber bundles in which multifilaments are bundled can be easily wound without being twisted, and can be woven thickly. Therefore, when it reinforces to-be-reinforced object, it can reinforce with few lamination | stacking compared with the past, can reduce the effort of reinforcement, and can reinforce.
また、マルチフィラメントを束ねた炭素繊維束の複数束を断面が３芯状や７芯状の多芯ロープ状に束ねた状態として、ポリエチレンやアラミド等の合成繊維糸の掛合糸を巻縫い掛合して、多芯ロープ状の炭素繊維束糸を形成することによって、マルチフィラメントを束ねた炭素繊維束を多芯ロープ状として掛合糸で巻縫い掛合でき、上記したように単繊維がばらけたり、毛羽立って剥がれたりせず、かつ炭素繊維束に弾力性を付与できて織物に製織することができる。 In addition, a plurality of bundles of carbon fiber bundles in which multifilaments are bundled are bundled into a multi-core rope shape having a three-core or seven-core cross section, and a synthetic fiber yarn such as polyethylene or aramid is sewed and wound. Then, by forming a carbon fiber bundle yarn in the form of a multi-core rope, the carbon fiber bundle in which multifilaments are bundled can be wound with a hook thread as a multi-core rope, and the single fiber is scattered as described above. The carbon fiber bundle can be woven into a woven fabric without fluffing and peeling off.
また、マルチフィラメントを束ねた炭素繊維束の１束ないし複数束にロックミシンのメローミシンで２〜５ｍｍのピッチで合成繊維糸の掛合糸を巻縫い掛合して炭素繊維束糸を形成することによって、マルチフィラメントを束ねた炭素繊維束の１束ないし複数束をメローミシンで容易にかつ迅速に合成繊維糸の掛合糸を巻縫い掛合して炭素繊維束糸を製造できる。 In addition, by forming a carbon fiber bundle yarn by winding and staking a synthetic fiber yarn hook thread at a pitch of 2 to 5 mm with a lock sewing machine mellow sewing machine to one or a plurality of bundles of carbon fiber bundles in which multifilaments are bundled, A carbon fiber bundle yarn can be produced by easily and rapidly winding one or a plurality of carbon fiber bundles in which multifilaments are bundled with a mellow sewing machine.
さらに、巻縫いした炭素繊維束糸を経糸および／または緯糸として所定の大きさの織物に形成することによって、マルチフィラメントを束ねた炭素繊維束に合成繊維糸の掛合糸を巻縫い掛合して炭素繊維束糸に弾力性を付与でき、また経糸切れ、緯糸切れなく、製織性を向上できて製織できて、上記したように手間を低減できて補強することができる。 Further, by forming the carbon fiber bundle yarns wound and sewn into warps and / or wefts into a woven fabric of a predetermined size, the carbon fiber bundles bundled with multifilaments are wound with synthetic fiber yarns and wound together. Elasticity can be imparted to the fiber bundle yarn, and weaving can be improved with no weft breakage or weft breakage, and weaving can be performed, and as described above, labor can be reduced and reinforcement can be achieved.
さらにまた、巻縫いした炭素繊維糸による織物を複数層重ね合わせて補強用材として使用することによって、できるだけ少ない積層とできて、被補強物を補強するようにできる。 Furthermore, by stacking a plurality of layers of woven fabrics of carbon fiber yarns used as a reinforcing material, the number of layers can be reduced as much as possible, and the object to be reinforced can be reinforced.
本発明の巻縫いした炭素繊維糸およびその織物は、マルチフィラメントを束ねた炭素繊維束の１束ないし複数束に合成繊維糸の掛合糸を巻縫い掛合して炭素繊維束糸を形成し、織物としたことを特徴としている。 The wound carbon fiber yarn of the present invention and the woven fabric thereof are produced by winding a synthetic fiber yarn on one or more bundles of carbon fiber bundles in which multifilaments are bundled to form a carbon fiber bundle yarn. It is characterized by that.
巻縫いした炭素繊維糸１は、図１のようにオーバーロックやロックミシンのメローミシン２を利用してマルチフィラメントを束ねた炭素繊維束３の１束ないし複数束をメローミシン２に供給し、この炭素繊維束３に合成繊維糸の掛合糸４を巻縫い掛合して炭素繊維束糸として形成するようにしている。 As shown in FIG. 1, the wound carbon fiber yarn 1 supplies one or more bundles of carbon fiber bundles 3 in which multifilaments are bundled using an overlock or lock sewing machine mellow sewing machine 2 as shown in FIG. A synthetic fiber yarn hook yarn 4 is wound around the fiber bundle 3 to form a carbon fiber bundle yarn.
マルチフィラメントを束ねた炭素繊維束３は、ポリアクリロニトリルのＰＡＮ系の炭素繊維や石油ピッチのピッチ系の炭素繊維などのものが利用でき、ＰＡＮ系は樹脂をマトリックスとする複合材料として優れた特性を有するので、特に軽量構造用に適する。 The carbon fiber bundle 3 in which multifilaments are bundled can use PAN-based carbon fibers of polyacrylonitrile or pitch-based carbon fibers of petroleum pitch, and the PAN system has excellent characteristics as a composite material using a resin as a matrix. It is particularly suitable for lightweight structures.
炭素繊維束３のフィラメントは、直径が約７〜１０μｍといった極細であり、これらのフィラメントを上記したように１０００〜１２０００本を束ねて０．数ｍｍ〜１ｍｍ位の太さとし、その際毛羽の発生を防止するのに少量の樹脂をコーティングするサイジング処理をしている。 The filaments of the carbon fiber bundle 3 are extremely thin with a diameter of about 7 to 10 μm, and these filaments are bundled in a range of 1000 to 12000 as described above. The thickness is about several mm to 1 mm, and a sizing process is performed to coat a small amount of resin in order to prevent the occurrence of fluff.
炭素繊維束３は、１束毎に掛合糸４を巻縫い掛合できるが、３〜５束の複数束、好ましくは５〜２０束毎に掛合糸４を巻縫い掛合するのが、炭素繊維糸１を太状ないし嵩高にできるものである。炭素繊維束３は、図２（ａ）のように１束であれば太状のものを、複数束の場合は図２（ｂ）、（ｃ）のように３束の３芯状や７束の７芯状、さらにこれらの外周部に軸対称に二重、三重状に配設してさらに太状ないし嵩高にすることもできる。 The carbon fiber bundle 3 can be wound with the hook yarn 4 for each bundle, but the carbon fiber yarn is formed by winding the hook yarn 4 every 3 to 5 bundles, preferably every 5 to 20 bundles. 1 can be thick or bulky. The carbon fiber bundle 3 is thick if it is one bundle as shown in FIG. 2 (a), and in the case of a plurality of bundles, it is a three-core or 7-core shape as shown in FIGS. 2 (b) and (c). It can be made thicker or more bulky by arranging it in the form of a seven-core bundle, and in the outer periphery of these bundles in an axisymmetric double or triple shape.
また、図３（ａ）、（ｂ）のように炭素繊維束３の空隙に小径の炭素繊維束３を介添して軸対称状に型崩れしないように安定した密な状態にすることもできる。 Further, as shown in FIGS. 3A and 3B, a small diameter carbon fiber bundle 3 is interposed in the gap of the carbon fiber bundle 3 so as to be in a stable and dense state so as not to lose its shape in an axial symmetry. .
掛合糸４は、ポリエチレンやポリプロピレン、アラミド等の丈夫な合成繊維糸が使用でき、０．１〜１０デニールの極細のものが炭素繊維束３に嵩高とならずに掛合できて蜜な炭素繊維糸１の織物に形成できて好ましいが、上記した太状や嵩高状の炭素繊維束３のものでは必要により１００〜２４０デニールの適宜の太さの糸を使用することができる。また、掛合糸４は、メローミシン２に供給して２〜５ｍｍピッチで炭素繊維束３に係合していくのが好ましく、かつ炭素繊維束３がばらけたり、毛羽だったり、剥がれたりするのを有効に防止できて好ましい。 As the hook yarn 4, a strong synthetic fiber yarn such as polyethylene, polypropylene, aramid, etc. can be used, and a fine fiber of 0.1 to 10 denier can be hooked on the carbon fiber bundle 3 without being bulky, and it is a nectar carbon fiber yarn. However, in the case of the above-mentioned thick or bulky carbon fiber bundle 3, a yarn having an appropriate thickness of 100 to 240 denier can be used as necessary. Further, the hook yarn 4 is preferably supplied to the mellow sewing machine 2 and engaged with the carbon fiber bundle 3 at a pitch of 2 to 5 mm, and the carbon fiber bundle 3 is scattered, fluffy or peeled off. Can be effectively prevented.
このように形成した巻縫いした炭素繊維糸１は、図４のように織物５とするのに経糸６および／または緯糸７に使用して平織、綾織等の所定の大きさの織物５を製織し、ばらけたり、毛羽だったり、剥がれたりするのを防止でき、かつほとんど伸縮性のない炭素繊維束に弾力性を付与でき、また経糸切れ、緯糸切れなくて製織性を向上できる。 The wound and sewn carbon fiber yarn 1 formed in this way is used as a warp 6 and / or weft 7 to form a fabric 5 as shown in FIG. In addition, the carbon fiber bundle can be prevented from being loosened, fluffed or peeled off, and elasticity can be imparted to the carbon fiber bundle having almost no elasticity, and the weaving property can be improved without breaking warp and weft.
この炭素繊維束３は、１束以上でよいが、上記したように複数束とすることにより、所定の嵩高のものが迅速かつ容易にできて強度を高められて好ましい。特に、図３（ａ）、（ｂ）のように炭素繊維束３の空隙に小径の炭素繊維束３を介添して密な状態のものが強度を高められて好ましい。なお、本発明の趣旨の範囲で適宜の太さのもので適宜の束数とすることができる。 The carbon fiber bundle 3 may be one or more bundles, but a plurality of bundles as described above are preferable because a predetermined bulky one can be quickly and easily increased in strength. In particular, as shown in FIGS. 3A and 3B, a dense state in which the carbon fiber bundle 3 with a small diameter is interposed in the gap of the carbon fiber bundle 3 is preferable because the strength is increased. It should be noted that, within the scope of the present invention, an appropriate thickness can be obtained with an appropriate thickness.
上記した掛合糸４は、図１のようにロックミシンのメローミシン２に上記した炭素繊維束４を同時に供給して、搖動昇降するミシン針８の針糸９に掛合糸４と同一の糸の上糸１０、下糸１１をかがり縫いして巻縫いすることによって容易かつ迅速に得ることができる。 As shown in FIG. 1, the above-described hooking yarn 4 supplies the above-mentioned carbon fiber bundle 4 to the lock sewing machine mellow sewing machine 2 at the same time, and the needle yarn 9 of the sewing needle 8 that moves up and down is placed on the same yarn as the hooking yarn 4. The thread 10 and the lower thread 11 can be obtained easily and quickly by over-stitching and winding.
このようにして平織り等の所定の大きさの織物５を製織していくことができる。織物５は、用途によってその幅を適宜に決定できて装着して、従来のＦＲＰやＣＦＲＰと同様に航空機や自動車、ボート、スポーツ分野や、土木、建築分野、通信装置、携帯電話、ＴＶ、医療機器、レーザー装置、その他の用途に対応して機械、装置、物品、構造物等の軽量、補強、電磁雑音防止などに有効に対処することができる。 In this way, the woven fabric 5 having a predetermined size such as a plain weave can be woven. The width of the woven fabric 5 can be appropriately determined depending on the application, and is installed, as with conventional FRP and CFRP, such as aircraft, automobile, boat, sports field, civil engineering, building field, communication device, mobile phone, TV, medical It is possible to effectively cope with lightness, reinforcement, electromagnetic noise prevention, etc. of machines, devices, articles, structures, etc. corresponding to equipment, laser devices, and other applications.
図１以下は、本発明の実施例を示すもので、図１のようにマルチフィラメントを束ねた０．５ｍｍ径位の炭素繊維束３を図２（ａ）や（ｂ）、（ｃ）のように一束ないし複数束をメローミシン２に供給し、メローミシンを駆動してミシン針８を搖動、昇降して１４０デニールのポリプロピレンの熱可塑性繊維糸の合成糸の針糸９を上糸１０、下糸１１を介して同様の合成糸の掛合糸４に３ｍｍピッチで掛合して炭素繊維束３に撚りがかからずに、したがって単炭素繊維糸が折れなくて炭素繊維糸１を形成し、図４のように製織機に経糸６および緯糸７として供給し、たとえば平編みとして所定の大きさに製織していくものである。 FIG. 1 and the following figures show an embodiment of the present invention. As shown in FIG. 1, a 0.5 mm diameter carbon fiber bundle 3 in which multifilaments are bundled is shown in FIGS. 2 (a), 2 (b) and 2 (c). In this way, one or a plurality of bundles are supplied to the mellow sewing machine 2, and the mellow sewing machine is driven to swing the sewing needle 8, and the needle thread 9 of the 140 denier polypropylene thermoplastic fiber yarn is moved up and down to the upper thread 10, A similar synthetic yarn hook yarn 4 is hooked at a pitch of 3 mm via the yarn 11 so that the carbon fiber bundle 3 is not twisted. Therefore, the single carbon fiber yarn does not break and the carbon fiber yarn 1 is formed. 4 is supplied to the weaving machine as warp yarns 6 and weft yarns 7, and is woven to a predetermined size, for example, as flat knitting.
炭素繊維束３は、１ないし所定の複数を供給することによって、図２（ａ）〜（ｃ）のように１束ないし複数の軸対称状の束となった所要の太さの炭素繊維束糸として、図４のように製織機に経糸６および緯糸７として供給して平織等の織物５を形成し、プリプレグ処理等を行なってできるだけ少なく所要数を積層して手間を少なく補強用に形成できるものである。 The carbon fiber bundle 3 is a bundle of carbon fibers having a required thickness which is formed into one bundle or a plurality of axisymmetric bundles as shown in FIGS. 2 (a) to 2 (c) by supplying one or a predetermined plurality. As a yarn, as shown in FIG. 4, it is supplied to a weaving machine as warp yarn 6 and weft yarn 7 to form a plain weave fabric 5 and the like, and a prepreg treatment or the like is performed to laminate as few as possible to reduce labor and form for reinforcement. It can be done.
図５のように掛合糸４は、炭素繊維束３のばらけ防止と、毛羽立ち、剥がれを防ぐだけでなく、ほとんど伸縮性のない炭素繊維糸にループ状となった掛合糸４で弾力性を付与することができる。その結果、経糸切れ、緯糸切れを起こすことなく非常に製織性が向上できる。また、掛合糸４を巻縫い掛合するとき、炭素繊維束３に撚りがかからずに巻縫いをすることができるため、非常に細く折れやすい単炭素繊維糸を切断することなく巻縫いできて、炭素繊維糸１の強度を低下させることを防止できるものである。 As shown in FIG. 5, the hook yarn 4 not only prevents the carbon fiber bundle 3 from flaking and prevents fluffing and peeling, but also provides elasticity with the loop yarn of the carbon fiber yarn having almost no elasticity. Can be granted. As a result, weaving properties can be greatly improved without causing warp breakage and weft breakage. In addition, when winding the hook yarn 4, the carbon fiber bundle 3 can be wound without being twisted, so that the single carbon fiber yarn that is very thin and easy to break can be wound without being cut. It is possible to prevent the strength of the carbon fiber yarn 1 from being lowered.
また、掛合糸４に熱可塑性繊維糸を使用することで、作製した炭素繊維糸１の織物５を加熱して容易に樹脂を溶融させた炭素繊維強化複合材料（ＣＦＲＰ）を成形することができ、成形工程の省力化ができる。 Further, by using a thermoplastic fiber yarn as the hook yarn 4, a carbon fiber reinforced composite material (CFRP) in which the fabric 5 of the produced carbon fiber yarn 1 is heated and the resin is easily melted can be formed. , Labor can be saved in the molding process.
なお、このようなＣＦＲＰの織物は、上記したように航空機や自動車、ボート、スポーツ分野や、土木、建築分野、通信装置、携帯電話、ＴＶ、医療機器、レーザー装置、その他の用途に対応してこれらの機械、装置、物品、構造物等に内装、外装して軽量、補強、電磁雑音防止などに有効に対処することができる。特に、炭素繊維糸の織物を上記した器具や装置に装着することによって補強の他に電磁雑音防止をはかることができて好ましい。 Such CFRP fabrics correspond to aircraft, automobiles, boats, sports fields, civil engineering, architectural fields, communication devices, mobile phones, TVs, medical equipment, laser devices, and other applications as described above. These machines, devices, articles, structures, etc. can be internally and externally mounted to effectively deal with light weight, reinforcement, electromagnetic noise prevention, and the like. In particular, it is preferable to attach a carbon fiber yarn woven fabric to the above-described appliance or apparatus, in addition to reinforcing electromagnetic noise prevention.
またさらに、積層する炭素繊維糸１を製織した織物５の炭素繊維糸１の方向が、図６のように交互に４５度等毎に対応するように積層して、積層する織物５の強度を所要の均一状に形成して利用することができるものである。 Furthermore, the strength of the woven fabric 5 to be laminated is increased by laminating so that the directions of the carbon fiber yarns 1 of the woven fabric 5 obtained by weaving the carbon fiber yarn 1 to be laminated alternately correspond to every 45 degrees as shown in FIG. It can be formed and used in the required uniform form.
なお、図３（ａ）、（ｂ）のように太径の炭素繊維束３の間に小径の炭素繊維束３を介添して型崩れしないように安定した密な状態にすることができるものである。 As shown in FIGS. 3 (a) and 3 (b), a small-diameter carbon fiber bundle 3 is interposed between the large-diameter carbon fiber bundles 3 so that the mold can be kept in a stable and dense state so as not to lose its shape. It is.
